Alright gang, I'm not giving up on you yet... call me stubborn, so here's my little essay that is going to cover 2 things with respect to the reasons for this post and air-bag jackets:
1. The "why's" of my perspective and motivation (don't feel that you need to reply, this is background info for the second point)
2. Consideration of airbag jacket technology via example presentation and explanation. (For any minds not yet solidified in opposition.)
So here is my attempt to provide clarity - not argue, not rebuttal, not anger, not touch any nerves... merely explain my thinking, and my intent behind adamantly presenting this topic.
In order for the reader to understand this post further and my point of view and consider the technology based on the merits and actual comparative review of it, I'm going to drop a few things from here on out that I think have been beaten into me so that we can focus on the subject (and ultimate intent) of the thread and posts for this subject matter.
- Skill: No substitute, no argument, even on priority for budgets. I'm in complete agreement. That being said, I will not discuss it further, (aside from how I view it in a paragraph below).
- Budgets: We all do the best with what we have, and skill should be funded first.
- Gabe's (lack of) Riding Experience: As pertains to skill, consideration or justification of a product or technology.
Going forward, I would also personally appreciate me not being used as prime examples in future posts as to obvious lessons learned... there are better ways than making assumptions and doing limits the scope of your own analysis and review to looking at me and anything I say with "beginner goggles". Instead of educating me in the analysis of my own actions, you close yourself off to new considerations simply because I am a beginner and as such, almost certainly cannot fathom the logic by which items were presented above. I would instead ask that the discussion going be focused on the actual merit and validity of the technology itself, not the validity of the rider presenting it by giving a qualifying criteria "you must be this high to ride" bar or skill/experience quota. I.E. Please don't execute that skillful newbie-swerve as to avoid any serious "head-on" consideration of the tech & subject. In other words, you don't necessarily need to take me seriously, but it would be nice to take the intended subject matter seriously, or even partially, do your own research and homework and present pros and cons, reasons for/against and I daresay try on my boots for a new POV.
--- Begin Act 1 ---
That being said and over with, I'm moving on to first briefly explain why this technology has (and please forgive the pun) such a personal "impact" on me (since there is an innate desire to draw conclusions and make assessments based on typical and subsequently non-relative experience). It's important to me that you actually understand my approach and understanding beyond a drive-by glance, so that you know the history and my approach to riding safety and that my perspective and approach will be inherently different than typical new riders.
Fear was addressed, but as it pertains to skill and conquering. While fear can and should be controlled (not dominating), to respect it you have to understand it - and personal accidents, drops and like. This means that a healthy respect of fear must also be learned, controlled and respected giving the rider more awareness. A new rider will not understand the full implications of making a bad decision without better understanding the consequences and results. (I consider this safety math 101.) Example: People know about road rash, but it doesn't drive home the point because most people haven't experienced or witnessed it being new riders. The same example goes for head trauma, torso, spine and most important of these: severe impairment and death. So (in my world) you have to learn all relevant fear (to a reasonable extent) to be truly aware of the scope of what it is exactly that you have to conquer and the full scope of the consequences.
Would I advocate new riders doing this? Not to the degree I have, (most people can't handle that level of review or exposure and require therapy afterward), however I would storngly advocate research into consequences of all sorts, testimonies so that they know and have a healthy fear of how they or others could end up. Most people rely on their own (always limited) experiences or a few of what they have seen. Few people have had that exposure (usually not willingly) to the primal, gritty reality for which often make people give up an activity before even starting it. How many new riders here have actually looked long and hard at rider injuries, death and stories beyond the initial shock value? How many have looked at the Hurt report statistics and additional studies since? How many have even Googled queries as to the actual real-world effectiveness of different types of gear and aftermath testimonies? I got the dreaded "evil eye" for even bringing up the topic of "rider injury types" in my MSF class... does anyone touch on that here? Probably not often, it's a taboo and often uncomfortable subject, why dealerships and salespeople rarely discuss it. Everybody talks about conquering fear and training to conquer it, but nobody talks about really understanding it. So in my head, you can't conquer what you don't fully realize and to train to conquer is to train for something unknown.
Why would you have to learn fear? Maybe the better question is, why would you want to learn some fear? Because guarding against complacency and overconfidence is the key to protecting against the unknown, surviving the unknown, the unanticipated and the unpredictable. This is the primary reason that people in risky professions are exposed to very strong "what if's" and "examples gone to hell" - to drive home the point so that the trainee is keenly aware of what NOT doing correctly. This is why I consider PPE (Personal Protective Equipment) a component of skill. If you're not skilled in protecting yourself, or only do half-ass, then you're not very skilled in my not-so-humble opinion at protecting yourself. Do I have all the top gear? Nope, I'm still trying and looking for better stuff, but I'm always looking and reviewing periodically or actively, because somethings might just justify the costs in my assessment, trialing and further review. Make no mistake, in my world - PPE is an integral component and fundamental link in my chain or circle of skill, there are no either/or extremes (a straw-man argument). Just something to keep that in mind for the rest of this post.
Thus I can sum learned fear up as:
Learned fear is required fundamental component to understanding and realizing the scope of a risk, and as such is integral in developing an approach to learn to conquer it. (Relative to the task / training needed.)
Now I'm going to tie this concept of "learned fear" as it pertains to PPE in 3 examples as they became relevant to myself.
Example #1 - EMT's are shown photos of real actual injuries and cadavers - sometimes in person. Training in class usually goes alongside actual calls, so students are exposed to real world situations as they learn. One of my very first calls (even before my EMT class) was for an extremely tragic incident - a pedestrian hit and killed by a drunk driver on drugs, namely an poor 12 year old child drug under a vehicle for about 1/2 a mile. Rest assured, you do not want to witness first hand what extreme road rash combined with a vehicle collision can do to make a human being no longer look human. This was a hard first lesson in mortality and the reality of our job and somewhat of an exception by even EMS standards. Working in the tangled leftovers of a fragile vehicle requires sufficient gear. We stabilized vehicles with wooden chocks, airbags and other tools. Ripped, sawed, tore, cut and separated more metal than I can remember - and I remember several instances of metal portions of cars popping off unexpectedly and hitting me, glass raining down on me, and sparks flying as material was either cut with circular saws, reciprocal saws or in some few cases oxyacetylene cutting torches - thankful for my gear. (Was always a fun training exercise to cut steel barbs and even melt concrete with that tool!)
Example #2 - Firefighters are shown photos of burns to both victims and fire fighters, fatalities, accident photos and more. We were later intentionally exposed to extreme steam (and thus experienced steam burns first-hand) to show what happens when someone opens up a hose incorrectly on a fire... a prime example of a single firefighter not doing his or her job correctly and how it can affect the outcome of the situation as the entire group hugged the floor in full gear and tanks, gritting teeth at our own sweat giving us 1st degree burns. We were also taught to use newer PBI material firefighting gear as opposed to the older "Nomex" gear of years prior. Both work, but one works significantly better than the other.
Example #3 - Soldiers are schooled in basic for chemical warfare and shown examples of what happens without their suits or having them improperly sealed. I will never forget those photos in my (brief) time basic training - it's what motivated us to place such a critical emphasis and priority on learning to don our suits quickly and correctly and bolstered motivation by driving home the reality of the risk. Pictures of soldiers and victims of gas, chemical and biological agent attacks, including people who had fault gear or did not utilize it properly (read: partial gear coverage). Not all died, but most lived a painful, often short remainder of their life.
Learned fear that is understood in scope in severity combined with proper instruction and repeated attempts and exposure results in a keen awareness of the reality of life and death (one of the first things I mentioned in prior posts above but which I think may have been not fully understood). Understand - this does not present with a ginormous glob of fear and does not a handicap me as a normal person might expect, (I'm already acclimated to this - even looking to get back to volunteering again as I greatly miss the service). What it does mean is that my approach is slower, taking more thought and attempting to be more methodical, cautious and slow. It means letting the pack ride ahead while I take turns slower, it means paying attention on group ride posts to descriptions about anticipated speed, types of turns, conditions and group ride expectations - and if not seen, asking questions about them. It means learning patience and taking my time. It means a more thought based approach in what I want to do out on the road with my bike because (at least initially) I have less control about external influences than I did when fighting a fire, when working in the mangled mess of what's left of vehicles in a collision or if I was in a foreign country with my platoon. I know that avoidance is sometimes not possible, I know that I don't know everything and I know that I can't anticipate everything. But it means I will try my best to do keep learning, keep trying and always, "train, train, train some more, mix it up and train for new as well as the familiar" (as was often repeatedly done in each of those areas). But it also means that particular emphasis is placed on learning and continually improving my PPE too because it is an integral component and because I have such a stark respect and awareness (realistic) understanding of what "can" happen to me or others.
This is what I call a "healthy respect" for the cruel nature of reality, (not an all-encompassing fear). It dates back to use of my PPE, ensuring my envelope is a component of your skill and complimentary, NOT in lieu of. To me, learned fear is part of my circle of skill - such as using a proper firefighting helmet instead of an old style leather one for style, upgrading to the newer more heat and fire tolerant/resistant PBI firefighting material in gear instead of our older Nomex training gear (still accepted in standards, but less effective & tolerant), and practicing to ride my bike slow and around vehicles by riding 100 miles in my neighborhood community before event going out into my first single-lane painted roads.
So to summarize this first main point - my perspective is probably unique, and so is my approach - if non-traditional. My safety recommendations here are NOT made from a gadgety "awe" or "cool" factor, and are based in healthy respect for reality that is rooted in my understanding of the importance and relevance PPE - and the consequences without them. I'm no expert, I don't proclaim to be - but I have seen enough accidents and tragedies first hand in how fragile we are and I know high risk this sport is (especially in this region), the fatal results of overconfidence involving vehicles and the completely surprised, unaware and predictable occur to even the most skilled and planned individuals (including other firefighters). Even the crazy occurs - like when you really just can't do anything in time what that deer jumps out of the bushes next to the road (and subsequently trashes of the front-end of an ambulance... we named that guy the "deer slayer"... now imagine that consequences to a motorcyclist.)
So when I recommend airbag jackets and I take on the challenge of explaining the benefits of new equipment, you now know the context in which I present this and the priority in which I regard PPE. If there is something for which can help mitigate serious injury or even death, I will throw it out. But to discard it without thorough review is only to potentially put yourself at risk, not me. Time for a breather...

Now to focus more on the technology. I think the way I could potentially best demonstrate the applicability of airbag jacket technology is through actual illustration and/or example (If you haven't read through the above links completely and haven't watched the videos - please do so). Mentally picturing something still permits bias based on each of our unique experiences and usually handicaps our ability to objectively review new concepts and tools. Trialing something out should present a more stark, if crude and fundamentally more applicable example for consideration.
So what exactly can air-bag jackets protect against?
Let's start with a quick pre-qualifier:
Remember that vehicles collisions and safety products are tested in attempts to replicate the most common scenarios or statistically largest scenarios for an accident. The same has been done for airbag jackets. Many have undergone tests, some rated even in other countries as new standards are being developed. It's a new tech, no doubt... but much like the first airbags in cars - even if imperfect, they provide additional benefits and protection over the lack of them when these statistically most common incidents occur. This being said, nearly all testimonies for rider protection that I've found involve the rider being ejected from the vehicle (usually by hitting another, losing control of the bike for X reason, etc.), with the subsequent protection applied as they hit the ground, nearby hills, other vehicles or even barrier walls. (I will see if I can dig up the list I found sometime this weekend of the numerous testimonies). While first generation jackets don't help any more than traditional jackets upon an initial collision, newer second generation jackets utilize electronic sensors to detect and trigger on the first moment of something starting to potentially wrong.
Due to the prior posts above, I can see that there is a misconception that these jackets are easily triggered or feared to be accidentally inflated. The chances of that are minimized with the programming of the sensors, and with tethers they require about 60 pounds of force (give or take by manufacturer) to separate and trigger. (If you get off your bike attached, decent chance you can actually tip your bike over... it is hard to separate and it is meant to be so that they are not accidentally triggered. The lifespan of a jacket is presented with each manufacturer when ordered along with recommended care, service and inspection instructions. All recommend after an accident to send back to the manufacturer for review and certification before re-using. If accidentally triggered, they are all re-packable provided no damage has occurred to them.
While an air-bag cannot protect entirely against a jagged sharp object such as a side rail on the side of a road, (for which little will), that is also why the jackets are augmented with traditional (usually upgradable) armor underneath the air-bags. I've upgraded my armor that it ships with (tough foam) to the hardest the vendor sells, and it may be further upgradable by using another brand/type in the insert. Newer jackets allow you to upgrade other hardened armor points too, elbows, chest inserts, etc. - many of the same / similar hardware points that traditional jackets and outfits provide (varies by manufacturer just as traditional jackets do). If a guard rail or piece of vehicle metal is sharp enough to cut into an airbag jacket and into the armor, good chance it will do the same for leather too, in which case your odds of survival are probably about the same. (Hopefully those all-important skill lessons will have paid off and this scenario will never come about, but there is always the unknown, and nobody can protect the future.) Air-bags are not full-proof protection, (and that's no my case nor point either), instead they are a form of ejection and secondary impact protection. In some ways they may be able to also protect against initial impacts as well, as inflation times have continually become faster and faster. Manufacturer testing (some in videos) show that even partially inflated they provide additional impact absorption and dispersion.
Now for the specifics in protection:
* Head and neck crushing and compression, twisting, extreme whiplash:
Cervical vertebrae are the most high risk and still exposed component. You may know firsthand about whiplash from a rear-end car collision, but this "always unprotected" portion of a person is difficult to protect against, particularly in crashes. In EMS we stabilize the head by holding it in-line with the body or in the position discovered if a neck injury is suspected, we rarely move it. The more you stabilize the head to act in-line with the larger mass of the body (or as one), the less chance for whipping around the neck and trashing your vertebrae and spinal cord in the process. When (equipped) airbag jackets deploy, they deploy an air cushion around the neck that greatly reduces the travel space between the base of a full face helmet and the inflated collar itself, permitting little if any travel (depending partially on neck length). Even with taller necks, the range of travel is severely limited. When a riders helmet (head) is impacted on a vehicle, the first counter-action that usually happens (besides the initial jolt to the helmet) is an extreme and immediate compression of the neck in the opposite direction of motion and travel of the rider (for example purposes just imagine a rag-doll when you press it head-first at an angle up against a wall. The neck of the rag-doll bends as does a rider's upon impact with a stationary object. Now put / imagine at least 2-3 fingers around the neck of the rag-doll and repeat... and you'll see there is less flex as the head moving and neck flexing motion is greatly absorbed (almost stopped) by your fingers.
* Spinal impact, compression, damage anywhere along the spine:
This is sort of a no-brainer. While you know your spine is strong enough to lift 100, 200 pounds, sometimes more, what people forget is that it's designed only that purpose... to lift and hold us up vertically. Very little protection and strength is present from an angle, side or perpendicular impact. (Ask anyone who has been hit hard in the back or has spinal damage.) What can damage a spine? A simple fall to the floor (my father-in-law is a living example of this right now. 2 weeks ago he fainted in the kitchen and probably hit a counter or the floor hard that shoved vertebrae and created bone fragments that are both pressing on his spinal cord - giving him a current paralysis of his left side). Remember my examples above? The body is extremely fragile and your spine is really no more protected than your neck when something hits it despite having more prominent larger bones. It doesn't flex as well, but that doesn't mean protection here shouldn't be paramount as neck and spine injuries are the most common and life-threatening debilitating vehicular injury in EMS for automobile drivers, much more so for motorcyclists (aside from the head being hit directly).
* Rib cage protection - augmented by upgradable armor padding as with the spine. Rib fracture and broken ribs are some of the chief problems for internal bleeding and death as they tear through the internal organs. If you have ever had a broken rib you know all about the pain... what you probably don't know is that bone can splinter, fragment and actually almost go flying through your chest cavity and organs if hit hard enough almost like a bullet. Because your rib cage is close to the surface, there is little soft skin, muscle, fat and tissue to absorb some of the impact. As such the rib cage is so very easily collapsible. I have accidentally broken ribs on patients doing CPR as have many doctors, nurses, medics and others... it's surprisingly easy to do, so this is also a key spot where impact dispersal (not absorption) is a critical component. Even if ribs break, if the majority of that is cushioned and spread out in an air-bag, the kinetic energy absorption eventually presented to the rib-cage itself will be a magnitude less if the impact is first made to the airbag.
* Tailbone/Hip protection - For the same reason armor was recommended above... armor + airbags distribute the force and permit the airbag to compress as it changes shape. The 2-4 inches of additional air-space (tough at that... not easily compressible), permits high impact absorption and reduces the force of the impact to your rear end. These can also result in lower-spinal injuries, broken hips (dangerous as they can in turn impact major arteries and lower internal organs). Due to the way that people go flying, if you look at the above videos you will see that a person's hips and rear become more exposed mid-flight before having the secondary impact. Remember, there is no way to protect everything with any solution but the most common methods for impact can be guarded against, and airbag jackets are an augment to the traditional layer of protection, not in-lieu of.
How can I drive these fundamentals home and show you? To illustrate these chief fundamental concepts, I could potentially craft a test and demonstration here. (I would be even willing to subject my own jacket to a controlled demonstration and comparison.) Such a (crude) controlled test might involve the following. (I'll consider this if parties are interested in comparing... I have at least 2 or 3 spare gas cylinders to re-pack and demo again after use.) Note: This is not an opportunity to show me up and "educate the new kid on the block in the error in the ways of his thinking", it's only if you're serious about considering improvements in YOUR safety, not mine. Keywords: Objective review for fundamental principles only.
Materials:
- Broom or mop with long handle, baseball bat maybe (something flat or non-sharp).
- Typical armored inserts used.
- Airbag jacket with armor inserts.
Test #1 - Don typical full PPE and have someone trustworthy use the handle or bat to give a small, gentle (but very tolerable) hit on the back over the spine. (One need not go crazy here as this is a little risky so this should start ridiculously light at first and the wearer should say said impacts are hard enough, a light touch is only needed at best to avoid injury). Potentially have the rider lean/semi-fall against a wall. Maybe repeat the same to the front of the torso and side of the rib cage. The rider should make a mental note of how each impact feels and describe them and across how widespread of an area it felt. Review the range of motion of the head and neck too - pay special attention here as this range would be indicative of the head travel that would occur in any accident involving a rider's head and helmet.
Test #2 - (Same rider) Don airbag jacket (with built in armor) full PPE, etc. as done prior. Repeat the same (gentle) test, describe differences in sensations of impact and surface area. Have the swinger again gradually increase the force. As a bonus, flop around on the grass or pavement with the jacket inflated to note the additional space separation of key areas of the rider from the hard surfaces. A little comical bouncing around on the ground will show that the air-bag is not soft, but very firm - intentionally so to permit compression of high-force impacts. (Should be done quickly as the vests start to deflate in 30-60 seconds after inflation - by design). Review the range of motion of the head and neck too - this part is very important... remember my note on spinal injuries above.
The tester can lean against a guardrail, other hard or flat object... possibly partially throw themselves on the ground from a sitting position. Repeat with both tests. The airbag is a textile jacket and the internal bag is tough enough to not pop like a party-balloon rolling around on say driveway concrete.Have someone else (not present from the initial review - to avoid bias/influence) try the very same tests then. Note results separately, then compare in a group review and discussion.
A moderate experiment:
Alternatively to having someone play whack-a-dude (and want to play it safer), we can then do the math behind example force (some equipment or tool used as a gauge) and impact through both sets of materials using a controlled / repeatable impact and level of force. While these are of course controlled limited and not entirely realistic conditions, they are meant to display dispersion/displacement of kinetic force and show absorption. Recall via your physics class of how force and kinetic energy is passed through materials... often to have an impact at the other end of the chain. Leather, foam and rubber padding can only absorb so much, usually directly and do not disperse that much. Air bags on the other hand, while having a smaller target area (intentionally for key area protection and also augmented by armor inserts of various sorts for additional protection), will cushion, absorb and relocate some of that energy.
A more simple fundamental (and safer) experiment:
Remember Newton's Cradle? (Google if you are not sure) Swinging that suspending metal ball transfers the force through the other balls with the biggest resulting kinetic action being the last one exhibits a near-identical swing outward. Now more dense and thinner material transfers this energy from one component to the next. If you were to insert a small balloon in the middle of Newton's cradle in place of one of the metal balls (same width - larger length to be representative of a jacket's larger surface are for energy absorption and dispersion), you'd see a notable and significant reduction in the kinetic output at the other end when impacts occur because the balloon of air absorbs and disperses some of the energy along a larger surface area (depending on the pressure in the balloon... the stiffer it is, the more energy passed on). This is relevant in that leather and armor are dense and as such pass more kinetic energy and potential through it to your spine and internal organs when a forceful impact occurs. (Try the Newton's Cradle experiment at home and report back on the results - remember the balloon should be larger and pressure scaled down to probably what a person can blow in.)
--- End of Act 2 ---
In Summary:
All demonstrations aside, this concept is already in use in every day life with the air bags in modern cars and trucks. They also can't protect against every scenario (which is why side curtain airbags are developed now and door air-bags... some with leg and knee air-bags now too I believe). But they are relevant for the most common types, for protecting against secondary and later impacts and help with ejection in general. Once ejected, it's not clear what a person will hit. The hard torso of a tree perhaps or a bunch of boulders, and an airbag jacket should help protect and mitigate impact injuries the moment the clip disconnects, or sooner if a sensor is triggered in a second generation system.
We already use airbag technology every day. Put a driver in leathers it might help, but you don't necessarily see NHSTA recommendations for drivers to wear leather jackets in cars. My core point in this is that we not necessarily replace traditional jackets or gear here - but ADD to them. This technology is an additional layer of protection and should be seen as such, NOT in lieu of. Note that while most airbag jackets are textile for flexibility and provide room, the first leather airbag jackets are now available (with just enough room for airbag inflation). Layering is the core technological component I am advocating here - "additional" safety protection for the most dangerous types of events. As a final disclaimer and reminder - airbag jackets won't cover all circumstances as I've thrown out above, but it will cover the most common and likely impact areas to the ribs, spine, some for the pelvis/tail area and neck.
Regardless of your stance or opinion on any of the above, I hope folks will take the time to objectively review this technology on their own, consider it as an "additional" layer of protection and do a little homework on their own. It may require keeping an open mind when doing so. I will also try and post the testimonies I have found to date as well. I hope people can now understand why I prioritize PPE and why make it one of the critical components in any equation for mitigating risk, other considerations aside. It is in this concern for the safety of motorcyclists that I opted to make this post, knowing full well there would be objections and strong opinions raised, as I have often seen in other forums in my online research as well. So it's my hope that everyone will review and potentially consider this technology, if affordable and appropriate for their use in mitigating risk.
