The irony of the situation you describe, Alex, is that it still exists to some degree, and people assume the airbag will save them even when they don't buckle their seat belts. But the truth is that the seat belt saves far more lives than all of those airbags combined. If you're not locked into the proper spot in the seat, the air bag might not be able to provide the cushioning that you need in an accident. All NHTSA estimates show that seat belts save more lives than air bags.

Well, that's certainly true, though I think the impediment towards consumer deployment of a 5-point restraint is that half of all consumers wouldn't understand how to use it and the other half would refuse to. Remember in the early 1970s, when cars had those shoulder belts hanging there limp, which no one wanted to use, or even could use, cause they were an afterthought?

Alex, you're exactly right about the crumple zone. I didn't get into it here, but I asked GM why they added this technology instead of knee bags, which are growing in popularity. They said the Acadia didn't need knee bags because it has big crumple zone in front to absorb crash energy.

Beth, there's been talk of center air bags for quite a while, but they haven't been added for two reasons: They are best suited for vehicles with lots of vertical head room, and they are an additional cost. GM didn't say this, but I think it would be tough to ever get this technology to trickle down to low-end vehicles like the Chevy Cruze.

The RACING COMMENT is spot on..

Our racecars are not required to have all the FEDERALLY MANDATED SAFETY BS SOLUTIONS.

I will not own a car with airbags and will make sure that the ones that I do buy have them are disabled..

I worked for a company that was designing robots for OEA out of the Denver area. Their speciality was explosive bolts ( for the military ) and AIRBAG IGNITERS ( AKA AIRBAG DEPLOYMENT CARTRIDGES ).

The reason they wanted robotic travelling handlers became very obvious one day.

The force of ONE igniter has the power of 1/4 stick of dynamite!

When you have a tray of SIXTEEN go off:

A three foot hole in the side of the bunker they were stored in

The panelling for the roof of the building was completely blown off!!

( the main force of the charges was directed upwards )

I do NOT like driving around with the equivelent of an m-80 inches from my face...You should also thinkof the person smoking a cigarette or a pipe and of course the person chewing on a toothpick...

The first time GM looked at the " airbag solution ", the  crash test dummies kept getting decapitated and moved into the back seat.

A FIVE POINT BELT system is good enough safety for our racecar. A THREE POINT HARNESS was good enough for my XJ12s....150MPH STOCK....

 

BTW, James Bond had the ultimate airbag safety system.  It was good for some laughs the first time we saw it...

From a design perspective, the best design is the one that gets the job done with the least complexity and cost. At the next viewing of a NASCAR or Indy race, count the number of airbags deployed in the event of a crash. A simple 5-point seat belt and better designed head support in the seat might be as effective as trying to add all the extra airbags. It would also be simpler and cheaper. Just because adding one airbag in the steering wheel proved effective over not having any doesn't mean that that it is the final or preferred solution to safety.

TOO MUCH!!!!

WOW!  What's next?  I have a far better solution......  Instead of contracting w/ mechanical & pneumatic engineers to rapidly deploy air bags, they should invest in advancing the technology of the expanding insulating foam which home builders are now using in exterior walls.  Of course, they'd need to get some chemists involved to provide an almost instantaneous expansion to be truly effective.  The best part of this plan is that since the front windshield is designed to pop out, the extra pressure created by the foam would force the window out, making it much easier for the EMT personnel on scene to extract the solidified mass.  With total containment achieved, the IIHS would not have to keep statistics on neck or back injuries due to whiplash or concussions from the driver & passenger banging heads, since they'd be totally immobilized.

So glad I can still get parts for my 1938 HUPMOBILE!  It doesn't have any of these modern-day accessories.

My friend hit a deer at highway speed and the air bag popped out. The air bag truly interfered with evasive manuvers - it almost put him in the ditch.

The car makers need to be careful. After the initial collision, very often there are control inputs that can and should be make. (I know from racing.) If you can't see or the vehicle is automatically disabled or if that bloody white powder from the air bag is making you choke and cough - not good.

Full volume air-cushion expansion-?

Alex, I curl a wry smile of acknowledgment to your statement of marketing ploy vs. actual safety concerns – the world is saturated with far too many unrealistic claims designed only to get into people's wallets.  However, when it comes to airbags, I think the more bags in a cabin, the better.  Watching the video clip showing the deployment, it is evident that even larger areas within the cabin volume could be covered with airbags in future models.  Moreover, I think engineers will solve the issue of restricted inflation due to lower ceilings pretty quickly, and seat-side bags will be seen on sedans and even compacts in the near future.  Seems like the vision has evolved from a "balloon on the steering wheel" to more of injecting total volume cushion for the inside space. Trending in the right direction, I believe,,,,

T-bone cushion

Nice details, Chuck. I didn't realize the driver and passenger bump heads in side crashes. I think this is a great idea. The t-bone is a nasty collision. It looks like engineers thought this one through.
