In this case the MEMS and pirotehnic capsule and electric parts, that together control the mechanical part itself - the airbag. Or, in short an ACU = ECU + MEMS + PYRO + CIRCUIT(CAN bus, signal lines, etc).

[@ludovicbon5903]

Very well explained . I spent ten years working in the airbag gas generator industry, focusing on quality and functional testing. For driver and passenger frontal airbags, the generators contain two pyrotechnic charges of different sizes that can be triggered with a delay determined by the calculator, depending on the speed of the impact and deceleration to modulate the deployment speed of the airbag so that it is fully deployed by the time the person makes contact. A few milliseconds of advance or delay are sufficient to avoid suboptimal functioning that could lead to inadequate protection or worsened injuries. For side airbags and curtains, the generators are hybrid. They function with both a pyrotechnic charge and a neutral gas under pressure, or nitrous oxide, to provide a colder gas.

[@amogusenjoyer]

It seems like there are a lot of airbag related recalls. Is it usually due to the pyrotechnic charge, or the control system that "ignites" said charges?

[@NewMind]

Thanks for the insightful comment. The fact that I did not encounter any mention of hybrid inflation systems during my research and interviews of several industry insiders really highlights how guarded airbag related IP is.

[@ludovicbon5903]

@@NewMind Hybrid gas generators are primarily used to protect against side impacts. This allows for smaller airbag modules that can easily be mounted in seat backs and interior pillars for curtains. Production began in the late 1990s. Each company guards its trade secrets closely while scouring automotive parts dealers and junkyards to recover airbag modules from competitors to see where they stand. This is also to avoid developing products that are too similar and could infringe on competitors' intellectual property.

Since everyone is sharing a story.... When I was 15, me and mum who was driving got into a crash on an empty highway at ~110 km/h in Croatia. We were in circa 1985 Opel Corsa. According to the cops we flipped 4 to 5 times. I got 4 scratches about 1-2 mm long from all the tempered glass side windows shattering. Mum hit her head on the roof and had slight bleeding from glass getting between the roof and her head and also she broke her window with an elbow so there was some damage from that. That's it. Yep, there were no airbags, but everyone was telling a story and I don't have one with airbags :D

[@mnxs]

The rolling part is what's important here, I would guess. Counterintuitively, cars rolling - assuming the roof is sufficiently strong so as to not collapse on the passengers - is actually often helpful in preventing serious injury, as the car's velocity is bled off over a large distance, instead of a much more sudden stop. It's facetious to say, but it's not the fall that kills you, but the sudden stop at the end. Had you _not_ rolled, my guess is you'd not be alive today.

Deploy on open isn't the best idea for a few reasons, one of the biggest is sensors degrading. Cars live an awful life for a machine being exposed to frigid temps, high temps, and lots of salt. Airbag sensors can often times form corrosion on conductors over time which can break the circuit open eventually. Having an airbag deploy while driving is pretty likely to lead to an accident on its own, with the unfortunate side effect of no-longer having an airbag. I know this is an old comment, but I'm scrolling so maybe someone else will too.

1:32 that is kinda cool how the emblem pops out n away.

Without a doubt...airbags have saved countless lives...mine included

i argue that the most complex system in the car is the driver as well as the single biggest point of failure.

A look at the history of something we see as trivial nowadays like the car airbag really makes you appreciate just how much advancement it took to make it mundane.

4:00 I wonder how many people died or suffered horrific injuries in the Niissan Tsuru, look at how the passenger safety cell completely crushed

I can't believe New Mind only has 500,000 subscribers. If you enjoy and appreciate the obvious effort and dedication put into these videos, then I suggest liking and commenting on all videos you watch. This way, we can help the creator get much deserved exposure via the KZbin Algorithm.

Airbags + seatbelt saved my wife when an oncoming driver fell asleep…. It was a 55mph head-on, and aside from bruises she walked away… ❤❤

10:04 was a bad moment to take a sip of water.

[@AdityaMehendale]

"Gee" is not a force; it is an acceleration. Uppercase G is newton's gravitational constant [m3 kg−1 s−2.]. Earth's gravitational acceleration is denoted by lowercase g (preferably with a suffix of lowercase n --> g_n ) having dimensions [m s-2] In a superficial/shallow "popular science video", I wouldn't bother pointing this out; in a NewMind video, this ought to be guarded meticulously.

[@NewMind]

Haha, in an ideal world I wouldn’t dare insult my audiences’ intelligence this way, but unfortunately, there is a business aspect to this so I have to take a more cartoonish, sensationalized description of things for the first minute or so to ease in new viewers.

That was a 40 mph crash at the beginning, not 15 mph.

[@shalala4571]

I was in a head on collision a while ago, both going about 70 kmh at the time of impact. Ambulance staff said i was very lucky, and i get the same impression after this video. No injuries, just a very bruised chest and a very sore body.

The “assman” license plate 😂😂 hard agree 👌🏻👌🏻

New York Assman. Such a classy license plate.

BMW now has an airbag subscription service. Each bag has to be paid separately, and if the system is not updated via their WiFi service, the airbag won't work.

[@nickhowatson4745]

that just isnt true and wouldn't be legal for BMW to sell such a car within the USA.

Without good government regulation, there would still be tons of new cars without basic safety devices like airbags.

I was visiting relatives in China and they were drunk and arguing with me about airbags. They tried to convince me they were silly. When I refused to agree they held me down and kicked my groin. They made sounds mimicking an air bag as they kicked me.

Why is the power off on a crash test vehicles. No lights on the dash I could see. Surely all electronics should be on to check for fires etc. ?

[@syntaxerorr]

Are mems based sensors not just miniaturized versions of their larger original versions?

[@mnxs]

No, I don't think you can say that, although they perhaps are built in a way that resembles microscopic spring mechanisms. Modern accelerometers can measure positive or negative acceleration as a three-dimensional vector to multiple digits of precision, whereas the earlier mechanical sensors were more like "on" and "off" - that's the point of the whole segment where he talks about detection profiles, advanced algorithms and computing power; all stuff that is decidedly _not_ possible unless you have very accurate data on the (crashing) car's movement and acceleration/deceleration in 3d space.

Am I the only one who noticed the “ASSMAN” personalized plate at 10:07 ? It’s from a Seinfeld episode where Kramer gets the wrong plate which was supposed to go to a proctologist. Lol

Lol at the Assman license plate

[@Shlooomth]

Love the way everyone is continuously passing over the fact that car companies knew the leading cause of death in America was car accidents, and they STILL resisted the effort to make them safer. Kinda reminds me of how the tobacco industry knew cigarettes caused cancer and selling them anyway. Or video game companies deciding to hook kids on gambling mechanics because they knew they could. But of course, the common problems between these scenarios CAN NEVER BE CAPITALISM.

[@nickhowatson4745]

the single biggest improvement in car safety is self driving technology.

[@Shlooomth]

@@nickhowatson4745 I used to be really optimistic about self driving tech too but idk it’s been a year away for over a decade now I’ve kinda lost hope

Was it not Cadillac that had the first air bag? If so Modern Marvels let me down. That show said it was an 800 dollar option on a 3.7k car.

[@McReinsen]

2:08 have to disagree here. an airbag is a passive safety system, yes. but so is a seatbelt. active safety tries to help prevent crashes. passive safety is trying to mitiigate/limit the damage.

[@tnekkc]

In the early 1970s Rocket Research in Redmond got a small contract for air bags. Dealing with Detroit was not like dealing with NASA. RR lost money. Years later airbags became popular, but RR never recovered any of the development money,.
