I would like to install a switch on my dashboard to disable/enable the drivers side airbag. If I cut the wire and put a switch on it, is there a risk of the airbag deploying when the power is suddenly turned on for it?

>> No.1730684

>>1730671
There is probably no power going through it until a crash anyway, so switch won’t cut/supply power. You might get an SRS light on the dash.

>> No.1730685

>>1730671
You should be alright if you disable the power to the "clock spring" disconnect the battery before you do.

>> No.1730707

>>1730671
But why?
Just don't fasten the seatbelt, airbag won't go off.

>> No.1730791

>>1730707
Airbags have blown out when people have worked on dashboards without removing the fuse first. I higly doubt that they'd have removed the dash while wearing seatbelts.

>> No.1730804

>>1730684
if the airbag ecu has power it should be performing continuity test to ensure airbag is connected/not deployed.
very common for any work on airbags not only disconnect battery but discharge/short terminals or wait for discharge a few hours.

big question is why do you want it enable/disableable?

least intrusive would be remove airbag and replace with suitable impedance to trick the ecu. depending on your location and use this could get you in a fuckload of trouble under inspection, but so does your original idea.

i have had supplemental service procedures for older cars that insists headlights and ignition must be on before reconnect battery to reduce chance of accidental airbag deploy because of power surges.

if you have a vehicle that is available in opposite hand drive you could frankenstien something with a legit passenger airbag disable switch. you need an opposite drive side ecu if the car is capable of deploying select airbags dependent on impact type, which they all do. but its still fucking sketchy.

I'm short, and from what I've read the airbags are designed with a 177cm standard height. The airbag must be good for any normal drivers, but I don't like to add risks like severed retinas and overall worse head and neck injuries than I'd have without this safety feature.
And of course, it would need to be able to be quickly turned on when switching to a taller driver.

At least with the airbags disabled, a wreck will take you out of the gene pool.

Then just crash into something slowly, so airbags deploys, and after that use electrical tape to pack it all back in. No airbag.

It can. They have bright connectors for a reason.

Jokes aside, modern airbag systems (I would say 2000+ year, but don't quote me on that) have sensors in the seat, which will weight you, and will adjust strength of explosion.

I understand where OP is coming from.

When my GF is giving me a blowjob while driving, I like to think safety first and disable the airbag to prevent her from unnecessary neck injury in case of a car crash.

Oh wait, turns out they're a hazard for tall people too: https://abcnews.go.com/Health/Healthday/story?id=4507147&page=1

>"This is the first time that there is proof to substantiate the concern about small-stature occupants, and it is the first time that there has been any implication that tall people are also at risk," said lead researcher Dr. Craig Newgard, an assistant professor of emergency medicine and public health and preventive medicine Oregon Health & Science University.

>While there have been reports that short people are at risk from air bags, that risk has never been conclusively demonstrated, Newgard said. "We found that small stature and large stature people, male and female, were at risk for injury from an air bag as opposed to having a protective benefit," he said.

>Newgard and co-author John McConnell collected data on 67,284 drivers and front-seat passengers involved in car crashes. They found that while air bags were effective for people of medium height -- from 5 feet 3 inches tall to 5 feet 11 inches tall -- they were actually harmful to people shorter than 4 feet 11 inches tall and those more than 6 feet 3 inches tall. Body weight was not a factor in injury rates.

I also like how it doesnt specify severity of anything.
Say you are short does it break your arm in a small fender bender as opposed to someone tall?
Great, it's still better than flying like a torpedo through the windshield in a big collision you dumbfuck. There is a reason you cant find anything new.

Nobody cares about data from 1997 with people wrecking cars from the 80s.

This. Cars today are so fucking safe it's incredible.
Was first helper at an accident where a Merc going 130 mph was hit from the side and was flying all over the fucking Autobahn.
Car was flipped and when I went to it I was expecting to be a goddamn mess.
Dude (who was short maybe like 5 feet 8 or so) just had like a cut on his hand.

My car's from 2005, so this is still very relevant. A new car is way beyond my price range, so making the best of this is the only option I got.

Airbags are worst invention ever made. Back in the day, drivers were calmer, because dashboards was made out of metal, and hitting those would be painful, seatbelts didn't exist, so even slightest accident will force you to replace windshield...

Depends on what car and if it only had minimum safety features.
I used to have an 05 Honda that had side and curtain airbags even though it wasn't mandated back then.

It's just mandated now in cheap new cars

just break off the wire from the back of the airbag so it looks like it was done by a shitty mechanic or just by age. Then dont worry about it with a taller driver. Just dont admit to being the one that disabled it in the event they fucking die and you wont be liable for shit.

What the fuck made you think this? Airbags happened because fuckers don't put on seatbelts. You may hav a specific vehicle in mind and are applying that to all but, it is not the case. I wish it were.

I wish they turned off if you connect seatbelt. It is redundant. I nudged the wall because someone changed lanes into me. Everything was under control before the airbag blew my hand off the wheel. Didn't even touch my face, because I had my seatbelt on.

>> No.1731497

>>1731483
Depends on manufacturer. Most European won't fire airbag if you haven't seatbelt fastened, because in this case risk of making everything worse is higher.
>>1731484
While it is true for old american luxury cars (ones that had lap seatbelt only, so real old), it is not true for modern cars.
In modern car you have SRS (supplemental restraint systems), where airbag works in pair with seatbelt pretensioner to make sure airbag won't launch you back into the seat.
This is why some cars will turn on SRS light, when you have problem with seatbelt
>>1731487

You're holding it wrong. Check owners manual.
