Title: Methods and arrangements for controlling an occupant restraint device in a vehicle

Abstract: Arrangements and method for controlling a deployable occupant restraint device in vehicle, such as an airbag, in which a crash sensor determines whether deployment of the occupant restraint device is required as a result of the crash and an occupant position sensor determines the position of the occupant. Deployment of the occupant restraint device is controlled based on the determination by the crash sensor if deployment of the occupant restraint device is required and the position of the occupant. The position of the occupant is determined preferably by ascertaining the position of the seat or a part thereof, e.g., the seat portion or back portion, relative to a fixed point of reference to thereby enable an approximation of the position of the occupant to be obtained. The payout of a seatbelt from a seatbelt retractor can also be measured and used to better provide the actual position of the occupant. An additional approximation of the position of the occupant can be obtained by receiving waves from the space above the seat in order to improve the determination of the likely, actual position of the occupant.
