On my dad's car, the middle back seatbelt has a pretty odd behaviour. It doesn't stretch at all if the car is moving, but it is allowed to contract. This means:
- if the person sitting in the middle has failed to buckle up or at least stretch the belt enough before the car started moving, now they can't do it until the car stops again;
- whenever the person in that place breathes out, they're running the risk of not being able to breathe back in next.
- when the car accelerates, there is a tendency for the person to weigh back into the seat. That causes the belt to contract.
Repeat the 2 latter points enough, and it becomes practically impossible to breathe or even to undo the buckle so you get trapped quite literally dying of asphyxia and in pain from the belt pressing hard against you.
- akerl_ 3y agoMaybe I’m missing something, but seems like your dad might want to take the car in for service. Malfunctioning safety equipment is a weird thing to let persist like this.
- cassianoleal 3y agoThe bit you're missing is that it's working as designed.
- akerl_ 3y agoWhat makes you say that?
- cassianoleal 3y ago* The fact that it's been through many full reviews * The fact that other cars of the same make and model do the same * The fact that (at least) some other models of the same make do the same * The fact that apparently I was the only person surprised at it when I mentioned to a few people who have cars of other makes as well * The fact that it was like this when it was new Perhaps none of these in isolation mean it's as designed but I reckon taken together they're a very good indication that it is as designed.
