  • Device for measuring force on a seat belt
    Patent number: 6993436
    Abstract: A measuring device for measuring a pulling force acting on a belt webbing of a seat belt of a motor vehicle is located between an anchoring point of the seat belt on the vehicle and a connection device which is to be connected to the seat belt. The connection device, in relation to the anchoring point, can be moved against a spring bias. The measuring device is a magnetic field sensor that is arranged between two analogous poles of two permanent magnets.

  • Linear pretensioning drive for a seat belt
    Patent number: 6676161
    Abstract: A linear pretensioning drive for tightening a vehicle seat belt has a guide tube. A piston is located inside of the guide tube and can be driven along a longitudinal axis of the guide tube. A reverse movement lock is formed by balls that are arranged on a ring around the longitudinal axis of the guide tube. In the drive direction in front of the reverse movement lock at least one support part is provided which lies against the inner wall of the guide tube in the locking position with in each case a greater supporting surface than each ball of the reverse movement lock.
