so my father-in-law was talking to me and my wife. long story short he said that he recently heard that all cars with airbags have the seatbelts tied into the airbag release system. with activation of the airbags a small canister of some chemical is released onto the seatbelt, effectively locking them permanently in place. in effect trapping you inside the vehicle.
my question to the sos thinktank, is this true? i’ve never heard of this. if it is true then i would be highly irritated. i feel seatbelts should be a personal choice that each of us as adults should be able to make for ourselves. but if the government is not going to give me that choice for the sake of ensuring my safety, then i can’t think of anything more dangerous than being locked inside a vehicle that has just sustained enough trauma to deploy the airbags.
Not only have I never heard of this, but it is almost certainly false. You can still remove the entire seatbelt assembly from any modern car and they are relatively the same as they have been for years. Basically they are a spring and cam system, with a weight is used to detect motion that should cause the cam to lock in place. The spring is primarily used for the belt retraction system. The only cars I have seen using a variation of this system in recent years, is the motorized seat belt system that was popular in the late 80s and early 90s… and even then the belt still worked similarly in some ways. I have not heard of something like this.
Ever hear of the systems they are working on to fill your car with foam? It’s nutty! I’d much rather have them just fill my car instantly with pudding, jello or mayonnaise.
