A kit for a device for restraining a vehicle occupant includes a prefabricated seat belt retractor (1) that has a winding shaft (2) mounted in a rotatable manner in a retractor frame (4) to wind up and unwind the seat belt. The kit further includes a similarly prefabricated drive module (30) having an electric motor (32), the drive module being connectable to the retractor frame (4) in a rotationally fixed manner. Force-transmission elements are provided on the drive module (30) and on the seat belt retractor (1) that are to be connected to each other to transmit the torque from the electric motor (32) to the winding shaft (2) when the seat belt retractor (1) and drive module (30) are assembled. An assembled device for restraining a vehicle occupant and having the components of the kit is also disclosed. Further disclosed is a set of electrical components that when assembled with the seat belt retractor provide a signal indicating the state of locking device that can lock the winding shaft from unwinding a seat belt.
An assembly for restraining a vehicle occupant comprising:
An assembly for restraining a vehicle occupant comprising:
An assembly for restraining an occupant of a vehicle comprising two connectable components including a complete and operational belt seat belt retractor having a winding shaft mounted rotatably in a frame for winding up and unwinding the safety belt, and a separate drive module selectively connectable to the retractor, the drive module including an electric motor and which is non-rotatably connected to the frame, and force transmission elements are provided which when the retractor and module are connected, the force transmission elements join the electric motor and the winding shaft of the retractor and enable transmission of torque of the electric motor to the winding shaft.
