How an Airbag Works - Takata Recall Explained
HTML-код
- Опубликовано: 15 июл 2024
- Here's an inside tear down of the internal components of an airbag, and how it works to save you in an accident.
An airbag works on the principle of a rapidly expanding gas that fills a balloon of air to cushion the impact of the occupant's head during a collision. The reactive compound in the inflator is sodium azide, which decomposes into nitrogen gas and sodium. This explosion fills the airbag within milliseconds, and the deflates allowing the driver to regain control of the vehicle.
The Takata airbag recall was issued to vehicles with defective airbag inflators that would inflate with too much force. This could cause shrapnel to explode into the occupant's face and cause injury or death.
In this video, a Honda airbag is taken apart as a demonstration to show the internal components of the airbag, including the airbag cover, the airbag balloon, the horn switch, airbag inflator and tamper proof electrical connectors.
Warning: Never take apart an airbag that has not been exploded. Any static or electrical current can set off the unstable sodium azide compound, causing it to explode.

"Death or even worse, injury" ))) man, you're awesome!
+K. M. Haha thanks!
Which you prefer?
Lol 😆 that was funny
Neither...
"Even worse, injury"
Lel
Injury is painful.
Clueless Drivers of South Carolina he has a point.
lol you mean "injury, or even worse, Death"??? you got it backwards there my dude lol
Think about it....... Using a brain.
tcpnetworks it's the same thing. Calm down.
I died once. I got an injury and I hated it. Injury hurts alot
+Tsunami Sushi but how did it feel to die by comparison?
Same.
Would have been glad if I stayed dead
Dude! Injury suppose to hurt you. What did you expect? 😂
If you died how did you comment?
@@C4PYMATIONS bro
01:42 "By carefully lifting it up"
drops it :))))
+Calin Pirlog whoops
"Death, or even worse, injury" is an accurate depiction of how a person would feel after getting shrapnel lodged into their face at airbag speeds and living afterwards.
meh, depends on wether they live in america or not. I can imagine most americans just going like "yea idk dude just wheel me out back and leave me there, or just shoot me if you can"
@@alexander-mauricemillamlae4567 And miss out on suing Takata? Get your 'merican stereotypes right.
Short and Crisp. I was always keen to know the mechanism behind these airbags, so Thanks.
And yes, I agree with you that Injury can be worse than death, sometimes !
Causes death or even worse injury lmao
+Frank Gard Which would you rather?
speedkar99 well I would like to live but if I was a vegetable after crash I'd wish for death. Either way your play on words had me laughing.
I agree with the sentiment expressed in the video
I'd assume death would be worse, but well I guess being injured is...
+13firebug13 it is indeed.
no one has survived death to tell us, so for now injury is worse than death lol
death you don't hurt. Injury hurts.
Taking shrapnel in the eyes and blinding you for the rest of your life is, in my opinion, worse than death.
Thought I was the only one who heard that lol...the guy did a pretty good job explaining things though
Just wanted to ad that there are 2 squibs(inflators) on modern air bags. You can tell just by the 2 connector's on the back of the air bag. One is for full deployment and the other is a smaller charge(60 to 40%). The smaller charge is used when the driver or in the case of front passenger is under 97lbs(each manufacture has slight differences) or in lower speed accidents.
Neat fact, those yellow wires and connectors are gold plated to have very good connections needed for hi speed signals from the SRS module in the event of a crash.
+Korrupted thanks for the clarification. I didn't want to risk opening the inflator to find that out the hard way
Quick, clear and concise. Thumbs up.
+Chosen Won Thanks short and to the point is how it should be.
My dude this video was excellent. Every word spoken was informative and the editing was clean and minimal. I'm sure if you keep making content like this you will see account growth.
Thanks. Please share my content in your network
I really like the fact that you used a 98’ old brown dirty ass toothbrush to explain the concept. It definitely made me understand it faster
Lol
awesome video brother..your topic selection is best
+Raju Yadav Thanks I'm glad you appreciate it my videos.
Nice video!
Was kind of hoping to see a demo of an airbag going off... mayve next time!
+Sulihack Thanks Sulihack,
Airbag videos are everywhere. But they throw them out when they're done and don't take it apart to explain what's inside!
man you were smooth and clear with your matter...
thanks! and I appreciate work effort
+Akshat Srivastava thanks for the appreciation
Very cool video! Straight to the points.
Thanks short and to the point is my style
Subscribed!
Nice to see those DAB assembly again, i used to work at Takata developing assembly machines for those airbags recall
Oh right, so you were the one who caused all this!!
speedkar99 hahaha you got me! That's why I'm no longer working there hehe :P
Thanks ! Very detailed and rare info till last screw in a airbag assembly
Awesome thanks
Airbag idea is awesome.
I'd like to say that I used to work on Takata Philippines. I am a formerly sewer of airbag there. this video is informative.
Excellent explanation. Thorough and succinct.
Glad you benefit from my work !
I think he said "it can cause death or even worse...injuries" i LIKE THIS GUY i HOPE THAT IF YOU EVER HAVE A CAR ACCIDENT YOU DONT GET INJURED! From the heart of my bottom!
Yep 😷
What's worse?
I like your sense of humor lol
+Living Lawhorn haha thanks
I didn't think I'm that funny
Hello
Living Lawhorn HUSH DAT LIP
Sodium Azide was not the propellant used in the Takata recalls that chemical was subject to clumping together in humidity. the propellant is a group of small cylinders that vary in size as to the amount of fill of the bag and the pressure required to escape the vinyl cover or dashboard. The azide does not have the clumping problem and thus does a controlled burn releasing the Nitrogen at a pre determined rate. The Takata propellent formulas clumping changed the controlled release to one fast instant deployment.
+ROBERT HARRIS thanks for the clarification
I love your videos - I show them to my physics students!
Nice, I guess I'm a teacher too
Excellent video fr teaching a listening skill in a Literacy session.
+raj andrew Haha true, thanks
Fantastic video thank you for sharing
Appreciate it. Thanks
awesome education. Thank you Regards.,
Best explanation. Thanks.
You are welcome!
good explanation
+Abdul Rahman thanks I'm glad you enjoyed it
Wonderful video!
+eddysun518 thanks
Nice info.
Love the way you said DEATH OR EVEN WORST "INJURY"
It's serious
@@speedkar99 agree dead is dead no more pain nor agony for loved ones the injury is opposite
Thanks man!
Excellent explanation
+Jamal Ali Thanks, I'm glad you found it informative.
Nice explanation
+Abhinav SS thanks
well done
Thanks for sharing!!!!!
+Дядя Федя glad you liked it
Love your toothbrush. LoL
Haha thanks!
U want his brussh 😊😊😊
+S Pradeep Kumar S Chandra Shekar thanks
nice to see the inside.
Thanks
I was an Electrician at a new Inflation Systems in Ga. One gram of the propellant in theirs was equal to the same amount of nitro gliserin. They had sniffers that detected the propellant on a micron level explotion proof drop doors and blow out pannels. And a rubberized plant floor because it was the same type of plant that in the 90s blew in Sarasota Fla. they now know there must of been alot of the propellant in the air A man hit a small staple or other metal object with a push broom caused a spark on the floor somehow They found cinder blocks 5 miles from the place. Yeah the start up of that place in Ga A pucker factor of 10 plus. The word for the day we all nervously said was Boom
+Steven Steele wow
nice video, thanks
Thank you
Good knowledge i also love your tooth brush
Haha
Good old pointer
You're a natural comedian
Wonderful Idea
Thanks
This was an oddly fascinating video for me
+Javian Johnson hah if you want to see more, check my other videos! Thanks
Nice information
Your welcome
Just the video I was looking for to understand where the metal fragments come from. Thank you.
Yea it's scarey thinking it could happen
Been driving my acura 2006 for ever. I just got this fixed recalled in 2020. Dude came to my house and replaced the inflator driver side and passenger side free of charge.
Your house ....nice
Hey, great video. Quick question for you. I need to take off the front plastic cover where the emblem sits on from my Toyota airbag. I don't need to remove the inflator itself right? I should be able to just remove the screws holding the cover to the horn springs and remove it? Any tips? I know a lot of mixed info out there regarding the inflator exploding but if it's off the car and there is no voltage then there shouldn't be a risk should there?
Another good video. I would emphasize that whenever you buy a car new or used, go to the manufacturer's owners page and register your car. Manufacturers use this to contact you with recalls and safety information. I bought all of my cars used and have registered them with Ford, Honda, Lexus and Mazda, and each company sent me an airbag recall notice. As a note, Ford has been the fastest on actually doing the replacement. I am still waiting on the others, but at least they notified me.
Thanks for the feedback. Yes the airbag recall is important, I decided to get mine done a few months ago. While doing some research on the recall I was surprised at how little information there is on what happens during the recall, so I made this short clip to show what's inside.
Nice vid
+Faizul Haniff thanks
Those vent holes are actually there because if you completely sealed the bag, the material itself would rip and wouldn't be there to cushion an impact.
+White03T4RV82WD true, and it allows the bag to deflate
Thanks sir
Nice video! I would point out: I believe that airbag manufacturers are moving away from sodium azide, due to its toxicity, and ammonium nitrate -- as has been used by Takata -- due to concerns of volatile shrapnel ruptures of the inflators.
I don't know about in Canada, although I am assuming it is the same everywhere: airbag manufacturers are, I believe, now switching to guanidine nitrate as the chemical used in the reaction producing the gas in the bag. Guanidine nitrate is believed to be less toxic than sodium azide and less prone to violent shrapnel rupture than ammonium nitrate. Hopefully that will remain true over time.
That said, I agree: It's best to play it safe and leave the handling of airbag inflators to folks who have been professionally-trained in proper handling of them. This is because that there is likely some inherent risk of explosion and toxicity regardless, due to the nature of the materials we need to use to get airbags to inflate in time to save our lives (until we can come up with something better, anyway).
One final remark: For anyone interested, Battelle Innovations has a slow-motion video here on RUclips of a Takata airbag inflator -- "pen-style", rather than "pancake-style", if you would -- actually exploding into shrapnel. Scary stuff imho.
+Lynda Gruen Thanks for the info.
"Can cause death and even worse, injury" ......wow!
Thanks dude
You are welcome
Another great video you should be a teacher your great
+Patty Razer thanks !
That’s very cool. Love it! Ps never touch one in person.
Scared?
airbags look so soft and squishy until you get into an accident and it feels like someone punched you square in the nose
This guy is very funny when it comes to contemplation of life's complexity...
Funny how so?
I googled "how an airbag works" and found this clip. Was impressed on the detail off rip. went to subscribe, but realized I already am! Never stop stealing your brothers toothbrush my man. 😂
They should link your video in these recalls ive been getting in the mail.
Sir i am working in air bag manufacturing company and I am told to how to use the air bags in car and thank you put for this video
Nice
Lol that toothbrush I love it, so funny, it makes me laugh so hard everytime I see it and it makes me feel really good. Thank you so much for using that toothbrush it's really great please don't ever get rid of it.
Omg I'm gonna go to the shops right now and stock up on toothbrushs and start brushing my teeth 4 times a day and also use it to demonstrate on things like he does... So funny lol. Thank you so much.
+Marwan. S haha I'm indirectly promoting good hygiene
I always like how Vice Grips can replace many special tools. 😂😂👍
do airbags only trigger from an electrical charge or are there other triggers such as heat or pressure?
That’s cool
thank u
Nitrogen Gas was the imposter. Lol
Why would the device be a time bomb if taken apart? I really want to get rid of it cos im gonna install A sport wheel and dont wanna mess with the airbag each MOT
great video!!!
i got a question, do you need to replace a airbag sensor (collision sensor) after a crash where the driver airbag deployed?
THANKS
+zonnyamor if its damaged yes
After having my face rebuild from taking a tree in the face bulldozing. Injuries consistence with folks eating steering wheels or windshields from not wearing a seat belt in a head on collision. I"ll risk the air bag and wear a seat belt. Thanks for the education on the bombs inside your car. I'm guessing a roll over would be less than interesting. Great video.
Ouch!
Seat belt and air bags, I say yes. Thank you for posting I always wear my seat belt. just like a pilot wears his.
You are welcome
You do realise the holes are to cushion the blow of impact. If the bag has already gone off, i doubt control of the vehicle is your priority lol The injury/death comment was good i give you that :P
+lordgeorgemaster yes the holes help release air during impact and shortly after explosion
Thanks
0:54 don't make fun of him, injury is much worse than death.
When you are dead you don't have to suffer from any pain or problems in life.😁
Yes
Good video...But I want to ask about one component in this system which I have heard a lot of time and that is Clock spring. Could you tell me what it is and where it is installed?
+Anurag Gupta see my clock spring video...and my steering column video
My 2005 Lexus Lx470 and Airbag was Light on in Guage Cluster
+Keralis Fnaf yes
Toyota solara!!!!!!! I love mine. 2001 toyota solara SLE v6 and I have over 305,000 miles on it. It's my daily driver and it's just a fantastic car.
+Christopher Simpson It sure is a nice car, I miss mine. I have a Camry now and it's not as good honestly.
thanks bro i checked my airbag and made sure it wasnt takata
Replace the defective inflated with another exactly the same genius
Takata makes its own timebomb airbag but without gases
That can cause death. Or even worse injury. Lmfao
Here's a game before you drive.
Everytime he says airbag, take a double shot of vodka.
Takata
Great video man, but where is the toothbrush?
Is it safe to remove the inflader/explosive off an airbag that hasn't been exploded
"even worse, injury"
oh lord!
Are the holes actually there to allow for control of the vehicle shortly after triggering the airbag?
I thought it was to vent out the air so the airbag was softer against your face.
+Durcaz It does both, vent it and deflate it. If the airbag remained inflated you wouldn't be able to exit the vehicle....it's huge.
if we close vent holes and let the gas in the bag , will it remain blown ?? nearly if i want to use the system as a landing system
+mousab almatarneh My feeling is the bag will rip
Is an injury worse than death?
Would you rather suffer?
speedkar99 nope
omg lol thats that best way to make a video interesting. your right about using your brothers toothbrush throughout your videos. amazing a big applause to you
+Aldo Boquiren thanks haha yea its an ongoing joke theme. Good fun
What about the excessive force itself, regardless of the metal pieces? The excessive force alone after time in humid, warm weather?
In Australia we have been told that the company Takata has gone into bankrupcy and that it may be some time before we will get any airbags replaced. I've been waiting a year for Jeep to call me back to get my airbags replaced.
+fourbypete and the meanwhile your driving like that? Scarey
Only when the airbags go off. Otherwise the vehicle drives normally. That is the second recall from Jeep for my car. I'm still waiting for them to replace the clockspring.
I’ve been driving a rental paid for by Lincoln Motor Company due to the airbag recall
You need a better lawyer.
So, what is happening with all of the returned inflators? Could have lots of fun with them.
+Anthony Lee I'm sure Honda is detonating them before disposing. Remember though they aren't replacing the bag, just the inflator.
speedkar99 it's not just Honda.
My concern is national security as these devices are very dangerous in the wrong hands. Not to mention the millions in automotive bone yards. These things can very easily be turned into IED's
Where I can buy gas generator inflator?
I like you man
+HASAN KSA I like me too
This inflator can be used only once ? I mean once an airbag has been inflated and for next time should we replace the inflator ???
Yes one time use. That's why it's so expensive to repair.
I have to subscribe because of the toothbrush hell yeah!
+Derrty92lude Oh there's alot more where that came from
I still want to see the inside of the inflator but don’t want to take one apart myself maybe you could do it
+Steve Leahy haha I was scared to grind open this one even though it was already blown
Sorry i have a question, can i change the plastic cover with a non crashed airbag (i mean Not used) and put the airbag in Other plastic cover (same model car), it is dangerous?? Thanks by this video 👌
Yea but you'd be drivit without air bags
