  • Patent number: 7475840
    Abstract: At least one function of a seat belt retractor by is controlled by an electric motor. Torque of which is transmitted from the electric motor via a coupling to at least one component of the seat belt retractor. After the application of the seat belt with the transmitted torque, the seat belt retractor is adjusted to a starting position for adjustable functions in normal driving conditions and in dangerous driving conditions.
    Type: Grant

  • Patent number: 7341216
    Abstract: A seat belt retractor has a winding shaft to wind a seat belt. A motive spring pretensions the winding shaft in the winding direction of the seat belt. An electric motor provides a torque that can be transmitted to the motive spring to change the spring force. A switch coupling transmits the torque of the electric motor drive to the winding shaft to retract the seat belt. To transmit the torque, a drive wheel, which is rotatably mounted on a shaft non-rotatably and coaxially connected to the winding shaft and which is non-rotatably connected to an outer spring end of the motive spring by a rigid rotational connection. A first active surface of the coupling is movably mounted against a restoring force to a component that is securely connected to the rigid rotational connection and rotatable around the shaft. A second active surface of the coupling is non-rotatably connected to the shaft.

  • Patent number: 7180258
    Abstract: A method and a device for adjusting a supply current, which feeds an electric motor, the torque of which is transferred to a belt reel of a seat belt retractor of a motor vehicle, whereby the motor current of the electric motor is measured during the torque generation and compared as a controlled variable with a command variable, which is adjusted depending on at least one driving situation or at least one driving condition of the vehicle, for controlling the supply current for the electric motor situated in the control circuit.
