bmw seatbelts wrong way round?????
5 Answers
can anyone explain why in some models of bmw cars, the seatbelt plugs in the opposite side to most normal uk cars?
a mechanic friend suggested it is for easier quick release in an accident, but then questioned his theory by pointing out that in an accident, all emergency services immediately cut straight through a seat belt to get to the casualty as quick as possible!
thanks in advance x

Given the relative strengths of the body shell and of a seat back it has conventionally made more sense to have the upper anchoring point for a seatbelt attached to the body shell rather than to the seat itself. That means that the clip ends up being in the centre of the car but it also means that the driver and passenger end up almost holding hands as they seek to buckle up at the same time.
BMW seem to have decided that their seats are strong enough to attach the upper anchoring point to the seat itself, which permits them to reverse the usual arrangements.
It might also have something to do with the location and efficient operation of the pyrotechnic pretensioners. See here:
