Well done - I learned a lot about airbags! thanks for posting
I am glad to know that Jared :)
Good to know Jared you survived The Snap.. 🔥 🤣
Make a video on t14 armata
Which kind of next video from your side on your channel
What a surprise.
When you realize all the things that happen when the airbag deploys, it's just insane how fast it all works.
Yes so fast
True

It's the middle of the day, there's lots of stuff I should be doing right now, plenty of hobbies n projects I'm still in the middle of, and I'm over here learning about airbags
This technology has saved my life two times. Thank you for such an informative lesson on this feat of engineering!
Guess your a bad driver😂

3:30 someone crashed into a tree nearby but these 2 guys just do their buisness, that is some dedication to the job.
He gave the other guy the key to success, no time to waste to save a life!
good one :D
🤣
All are sold out...but still that accidental car is there ....#strang 🤣🤣🤣
looks more like a demo version outside the showroom! ;)
I work in an airbag and seatbelt factory here in the philippines, the work is very meticulous, the sewing needs good quality for everyone's safety.
Thank you for saving our lives
I am working Automotives Engineer pleasure to meet you
Great
Thank you!
@@aboghally497 bro it's my dream to become automotive engineer. Can you tell me what to expect if I become automotive engineer? Thanks
mesmerizing voice.. you just nailed it.. what an eye catching illustration.. fantastic..
This invention is literally a life saver. Kudos to the people who made this.
Good video. I worked with Airbag and Seat belt and Seating systems years ago. I didn't notice anything wrong with your presentation. Additional things you could have mentioned are: seat belt pretensioners that deploy before the airbag to make sure the seat belt is correctly tensioned, and that the passenger seat sensor determines whether to deploy the passenger airbags (specifically). A good idea is to link to your seat belt video at the end because RUclips's algorithm might not.
Didn’t he talk about torsion bar ? Well that is a pretensioner phenomenon.
We are glad to kow that an expert in this field like our video. Yah, watching the seat belt video before this video will make things more clear.
I also work a lot and airbag system and I love all the details and work that was put in this video.. btw the gyroscope / yaw rate sensor I notice is actually built in a lot of airbag ecu.. I had soo many shops and customer that pop all the airbag just by touching the airbag unit with ignition on and pop all the curtain bag because they car think its about to roll over..thanks to the gyroscope sensor in them..some times they use impact gun to take the airbag unit out and pop goes the bag (cause by the vibration from the tool)..some cases they disconnect battery and went and touch airbag unit and the static from their body surge though the airbag unit and pop goes them hahaa... I seen too many cases
Could you tell me, then, how the front passenger airbag deploys?? On my car, there is no "door" or anything for it. The whole top of the dash must blow off?? With the driver airbag, the steering wheel cover just has to break free.
@@drpoundsign What vehicle and trim level do you have? If someone has access to A2MAC1 they would be able to see what the exact construction is. There probably IS a door in the plastic substrate but the outer skin of the Instrument Panel hides it. The IP substrate construction might be what we call "Foam in Place". It is an injection molding 2-shot process where the hard plastic is injected first (it has the door), then the substrate is placed in another mold which tightly seals to it everywhere but the top "A-surface". Finally, the soft "skin" (which is just a more rubbery plastic) is injected to it. So that's why you don't see it anymore. I am just guessing since I do not have the part in front of me.
I am in favor of airbags, when you have your seatbelts on. As a retired firefighter I've seen them save lives many times. However I will never forget the Thanksgiving two cars just bumped corners (not even enough to destroy the lights) and the passenger airbag deployed. There was an unrestrained 5 year old girl in the seat who had bent over to pick up a toy in the floor board. She was hit full force, inches away and died instantly. Probably the single most horrific thing I have witnessed. Airbags are great when used properly, please make sure everyone has on their seatbelts!
Why was a 5 yo even on the passenger seat
@@Juanoodi exactly my thoughts at the time!
They should tell that airbags can kill you (in the tv), instead of making the car beep for 10 minutes if you don't put on the seatbelt.
Isn't it illegal for children to be on the front seat unless you disengage the airbag exactly because they are lethal?
(I know it's illegal in Italy, just wondering if in America it isn't)
@@wisteria3032 yes, it is.
Thank you for those who studied to save lives, your work is more than getting money, your work is about SAVING LIVES, TKS A LOT FOR TO BE AN ANGEL!!!
This girl looks so calm and comfy and keeps crashing into things. I would think she enjoys it a lot if I didn't know better.
Your animation is quite good, quite easy to understand even for people from non scientific background. And for me, a science student it is absolutely enjoyable
The Earth is Flat.
@@danielmconnolly7 Trump and Modi are wives
Know about Airbags, lot a thanks
@@danielmconnolly7 🤡
One of the best videos to understand Airbags.
I really loved how we chose woman for the demonstrations. 😂
My mom had an accident a few years ago with a Hyundai (5 seats) car.
The airbag didn't open even if it was armed but compared to a normal accident she was hit in the back-side of the car by another car at around 75 km/h while she was taking a right corner (so she had relatively very slow speed herself making the impact force IMENSE.
She got a head injury but was better in a few weeks.
The reason for the airbag failure might be due to the car being hit in the back not in the front where most sensors are.
Get well soon to your mom.
And also good point.
All airbags only inflate if hit from front
Nah. Mine got hit in the front and after the vehicle "came to rest", I watched both airbags deploy: driver side blue, passenger side white. Sometimes they just don't work.

speaking of potholes, I used to be scared of airbags deploying just because of potholes. and eventually, just in 2019, I ran into a very deep pothole one night and thankfully the airbag didn't deploy. the dashcam came off from the windshield though and I bit my tongue lol. at least now I have peace of mind that airbags don't usually deploy just because of deep potholes 😄
Go to Victoria, Australia, out potholes are horrid
Visit India
Potholes are like hell.
U can also feel off roading even while you are on road
Yeah Nigga, Fosho!
@@nigmane racist pig
Really good no nonsense informative videos you present. No bogus introduction and subscribe drama at the beginning, but straight to the point. It's really impressive and important how clearly and simply you explain things, and in a progressive manner. Kudos!!
right? I saw one of their videos where they suggested becoming a patreon at the end. I got ready for the usual 10 minutes of explanation of why it is a good idea but by the time I finished rolling my eyes they were already done. As in they said "consider becoming a patreon" and that was that. Had mixed feelings about it (very happy but felt somewhat betrayed in my expectations).
@@wisteria3032 It's largely okay to have that at the end. The creator is positive that viewer will watch till end. Compare it with 2 mins of beginning drama asking to subscribe, bell icon, and then Intro sound with unwanted animations and then the presenter will still say Hey/hi I'm going to present this and that ... By that time THIS kind of awesome video is already halfway through the most interesting part. And those self advertiser would eventually present nothing concrete.
@@vvajay Yeah - I agree with you. I'm saying even when someone puts it at the end it's usually a very detailed and long request whereas this one was maybe a phrase and that was it. I was like "wait, where's the rest of it?". It was quite a pleasant surprise but it left me a bit dumbfounded.
I was in a car crash with my mom (nothing severe) and I was about 6 or so at the time but I still vividly remember the smell of the airbags. I am 21 years old now.
What did they smell like?
My respect for the engineers that come up with incredible idea that saves millions. ❤
This brought back memories of my first job in the automation industry back in the 80s. I worked at a company, Advance Automation Systems Corporation, in Simi Valley, where we made three automated production machines for AT&T, so that they could produce the magnetic ball switch for these systems.
The assembly went through a final continuity (Ohms) test for the contacts and the magnetic field (Gauss) was verified as well.
My car's takata airbag was just replaced in a recall this year. I recall a documentary where people said Takata airbags that failed QA would be put into cars. That documentary also said that the chemical was never changed - they just added something to absorb moisture, but that eventually when its absorbed as much as it can, you have unstable detonation again.
I work at an airbag factory in germany where we manufacture the generators. The quality control that every small element goes through is simply astonishing.
You mean the azide pellets?
U cleared my doubt from ages!!! Thank you very much!!!
The Great lengths people go to help humanity is simply amazing.
Awesome explaination. If teacher and professors in academic institutions explain this well to masses within a decade India will create revolutionize itself at 10x the current speed.
I love the way you teach. Thank you!
I just couldn't stop myself from watching this video to the end. 👏
വളരെ നന്നായി വിവരിച്ചു. അനിമേഷൻ അടിപൊളി.. 👌👌
I worked for and personally knew Allen K. Breed. He was a remarkable man, a literal genius.
What happened to him?
What an amazing video this is. Now I know how this system is working
Any knowledge gained is a gift
Me and my mom were in a crash on Aug. 13, 2021. We were ni a 2008 Cadillac CTS. We called it the "Black car". We were headed down street not even a quarter mile from home. A drunk driver hit us on the side at 80. The airbags were powerful enough to make me and my mom go deaf for a short time. If it was any closer to any of the doors we would have flipped over.
Thankfully I've only ever been in one crash where airbags deployed. In July 2016, I worked back to back 12h shifts at my job without sleeping a wink in-between, and I fell asleep at the wheel of my 2003 Chevy Cavalier in heavy traffic on the interstate on my way home, and just plowed into the back of the car in front of me at 25-30 mph. I was going slowly enough that I didn't even hit the airbag with my body or head, the only "injury" I sustained was scrape-like rashes on the side of both hands, where the airbag had rubbed over them as it deployed.
このチャンネル、本当に勉強になるな。
義務教育で毎週１本ずつ流してもいいくらいだ。

Great job! Best educational content ever!
This person explain it so good that he should not even get any bad comment 👍🏼
Fantastic video! Loved to know the evolution of airbags.
Once an airbag exploded in my face, i was copilot and i the crash caught me off guard, i was slightly leaning forward and the airbag slapped my face. It was like a hand slaping my face at 320km/h.
This is extremely informative. I came here to refresh my memory and learned new information. Thank you! 👍
Saved me from serious injury. Thank you smart humans 🙏
This was truly brilliantly explained ! 👍
I think the bigger question is, why is this woman repeatedly driving into boulders in the middle of the road? And why are there boulders on the road in the first place?
I loved the animations and narration in this
Engineers are a really brilliant type of people.
Thank you for the information. I didn't know that seat belt and airbag are interconnected.
Normally I release the belt just roubd the corner before coming home.on this day I didn't release the belt .luckily the airbag worked just round the corner.
You made it so clear.Thank u lesics for making such amazing video❤️
Very well explained. Thanks
This video was so concise and informative.
Thank you for a great tech history with explanation & animation.. Cheers
Last year, I met with an accident. Air bag saved me.
Thanks to sir bag
That's very interesting and informative, thank you!
A good comprehensive informatory video presentation giving clear knowledge and importance of Personal Safety Gear.
You explained everything so clearly but two things. How did that bolder get into the middle of the road and why didn't she see it? (Ok, just kidding here about the bolder and the driver's vision.)
Women drivers?
Because driver is female
It's a BMW, the expectation is that everything will move out of its way.
Fall from cliff or mountain?
@@vankuro4453 .
It’s amazing how much goes into the production of your car that people take for granted and just brush it off as being “overpriced”
Its actually crazy how your airbag purchase comes with a whole car!
And you can't buy this azide stuff online, unless you're a scientist.
Great video! Thanks for the explanaiton about airbags.
Thanks for this very wonderful & iinformative video. 🙏
Good video and informative video! 👍
Also the animations you guys do are amazingly detailing the point across.
Only 2 small nitpicks: in the beginning of the video the wheels turn left before the crash and the steering wheel hasn't turned left.
And near 5:33 the character model seems to get into a crash animation and returning to default position before the crash. And then during the actual crash the character model is static and shows no animation.
I know, I k know.. It's nitpicking and the those small things doesn't take away from the information.
You guys rock!
I'm subscribed for those amazing airbag fluttering animations.
Amazing methodology to explain this technology ☺️
Best meal for my mind, thanks for sharing
As always an awesome video Lesics. Great job.
The airbag is proof that technology can be used for something good. Thank you for a very informative video.
Finally got the answer to my question! Thanks!
Thanks for posting.
nutshell from me who experienced airbag deploy/car crash: u dont feel anything except huge BOOM, smoke, sulfur smell and weird loud noise. (i got the bad position at the front and my doors were a broken a bit so remember, if u are in a crash then get out of the car at any chance because if you won't then sometimes it can be your last car drive because something can mess up and uh, ya know, car would get on fire or someting bad so it's better to not risk. also if your doors are slammed then kick them because you can buy new car but you can't buy new life)
I like how she managed to crash into a huge rock in the middle of the road even though the road is wide open
Thanks for posting!
Great visuals!
All along I thought that compressed air was used to inflate the airbags. After all, air bags are not inflated by air! Very instructive video. One must salute the diligence and creativity of the engineers who designed the product.
this is wonderful explanation, i was always wondering how airbag work ever since i heard the word of it since like 20 years ago
I learnt a lot from your youtube videos..clear explanations and even a slow learner will able to understand
Thank you. Great job
Wow, what an internal mechanism behind this life saving air bags 👜🎒💼, truely hats off to the engineers for bringing this 💡idea
Women are best way to explain accident
- lesics
Such a huge useful information.
Your all videos are just amazing keep Posting thank you❤️
You explained very well.☺️😊
Excellently explained 👍🏻👌🏻
I really love your video. Thank you.
Thank you brother
Perfect idea
The car being used as a model is a BMW X6. Every detail is almost accurate to the real car
You mean X6
@@arturmd1642 My bad it is an x6 I looked to quick
I've been in one accident I cab remember where the airbags went off. The exhaust gas irritated my throat for days after. I didn't actually witness the airbag deploy because I blacked out before I hit the car in front of me
Thanks for your sharing I love this video ❤️
the best engineering Channel
I really thought lesics as god of engineering . Superb sir ur doing great job . Thank you
There was an incident in which a family didn't know about the seat belt's need for the activation of airbags, and sadly they died from the crash, there family registered a complaint against the car company thinking it was a manufacturing error, and they never reached anywhere as the necessity of seat belt was common for every model and is explained in the manuals.
They bought the car for the exact reason of airbags yet it never helped them in time of need, because of lack of intel and taking safety measures too lightly.
The point is, if you dont follow the guidelines for safety, non other will be responsible for your damage and you will have to suffer it painfully...
Its like owning a fire extinguisher without knowing how to use it.
they never read a user manual and yet they sue the maker... only in America
Nicely Explained..Great
Excellent explanation !
Great video but you've actually got a few things wrong in this one!
The Takata recall was due to them using Ammonium Nitrate NOT Sodium Azide as they swapped to a cheaper material while most Inflator Manufacturers were trying to distance themselves from Sodium Azide due to its toxicity. It is Ammonium Nitrate's sensitivity to temperature changes and moisture that caused Takata inflators to rupture which is also why ruptures are more common in more humid areas.
100% agree. Sodium Azide was the original chemical used in airbags. Takata then changed to Ammonium Nitrate (aka PSAN). It is the Ammonium Nitrate versions that can rupture and have had a global recall now reaching 100 million airbags.
Most airbag manufacturers now use Guanidine Nitrate in the inflator.
Other than that, great video. Just need to redo the audio with correct terms and it would be perfect.
I wish i never see this beautiful technology in reality
Thanks For Explaining the Amazing technology
Thanks for posting. Informative
Ah yes, airbag lore.
They are called SRS and this should be spelled out: Supplementary Restraint System! So it is in ADDITION to the seat belt. But some cars have belt pre-tensioners. If you have up to 9 bags popping you want to remain in the seat as tight as you can.
Very informative video
Thank you 💗
Thank you
Amazing tutorial with the animation
My biggest takeaway is that hitting an airbag without your seatbelt is more lethal than hitting your steering and dash without your seat belt.
i gotta tell you this story...
Today i was driving back to school with my friend,
i was a lil bit heavy with the pedal and after a powerfoul start my car (Lancia Y 2013) drifted, reaching around 30 km/h, until i faced a wall,
Obvsiusly i pushed as hard as possible on the brake, and i think i crashed into the wall around 20/15 km/h,
unluckly the airbags opened and we were shocked because it happened so fast and we were going so slow.
After realising what i did (and nearly soffocated by the bad smell of the airbags) i got off the car and checked the damage done... BELIEVE ME... Just a moved front bumper and a cracked light.
THE GOOD(or Worst) Part of the story is that under my leg i found a Plastic Heart (i assume was a part of a Bracelet) around 1 cm in height and width, which almost surely has to be hidden under the plastic of my steering wheel and THIS HEART LEFT ME 2 DOTS IN MY FORHEAD after the Airbag hitted my face....
Neither me and my sister (who was the previus owner of the car) know where this heart comes from.
Obviusly the most painful hit i received today... is on the WALLET
Thanks for reading.
Italian guy.
Incredible science behind this.
thank you for the information it's really helpful
