Abstract

A method and system for restraining an occupant on a vehicle seat, the occupant being pulled into the vehicle seat is provided with a force by a belt tensioner when a critical driving state is detected and then held in a pulled-back position on the vehicle seat with a holding force. The holding force selected is lower than the force for pulling the occupant back. A forward-looking detection system for a dangerous driving state and an occupant-position detection system unprovided, in which, when a dangerous driving state is detected, a belt tensioner is subjected to a force and the occupant is thereby pulled into the vehicle seat, and in which the occupant is held in a pulled-back position on the vehicle seat with a holding force which is lower than the force for pulling the occupant back.
