Occupant restraint arrangement for motor vehicle restrains occupant with belt in event of emergency and enables safety belt to be extracted if load in excess of defined load is exerted on belt

摘要

The arrangement has an impact energy absorption mechanism for preventing the extraction of a safety belt to restrain an occupant (14) in the event of an emergency and to enable the belt to be extracted if a load in excess of a defined load is exerted on the belt, a device (62) for detecting the extracted length of belt, an extraction rate computation device (110), a vehicle speed detector (112) and an occupant acceleration computation device (114). An Independent claim is also included for a method of controlling an occupant restraint arrangement for a motor vehicle.
