초록 ▼

A method and vehicle occupant restraint system for a motor vehicle, in which the webbing movement of a seat belt wound on a belt reel 1 caused by the body of the belted-in vehicle occupant is scanned and corresponding measurement data are fed to an evaluating device 3 , wherein measurement data relating to the rotating movement of a rotor 2 , in particular the electric motor rotor, which serves in tightening the seat belt webbing, may additionally be fed to this evaluating device 3.

대표청구항 ▼

1. A vehicle occupant restraint system for a vehicle comprisinga seat belt refractor for a seat belt,a bolt tightener drive, the drive moment of which may be transmitted by a rotor to the belt reel of the seat belt retractor,a torque transmission device exhibiting a given damping behavior transmits the drive moment to the belt reel,a first rotational angle sensor for scanning the rotational angle of the belt reel, the first rotational angle sensor supplies an electrical signal corresponding to a rotational angle of the belt reel to an evaluating device that determines from the electrical signal and the damping behavior a force acting upon torque transmission between the sear halt and a belted-in vehicle occupant, anda second rotational angle sensor for scanning sensor for scanning a rotational angle of the rotor, wherein the measurement data from the two rotational angle sensors are supplied to an evaluating device, which performs a diagnosis of the operation of the seat belt retractor by evaluating the measurement data supplied by the rotational angle sensors. 2. The vehicle occupant restraint system of claim 1, wherein an adjusting device for a belt force limiter is triggered as a function of the determined force. 3. The vehicle occupant restraint system of claim 1, wherein the torque transmission device may be switched to a particular transmission mode as a function of the diagnosis result. 4. The vehicle occupant restraint system of claim 2, wherein the torque transmission device may be switched to a particular transmission mode as a function of the diagnosis result. 5. The vehicle occupant restraint system of claim 1, wherein the rotor is the rotor of an electric motor comprising the belt tightener drive. 6. The vehicle occupant restraint system of claim 2, wherein the rotor is the rotor of an electric motor comprising the belt tightener drive. 7. The vehicle occupant restraint system of claim 3, wherein the rotor is the rotor of an electric motor comprising the belt tightener drive. 8. The vehicle occupant restraint system of claim 4, wherein the rotor is the rotor of an electric motor comprising the belt tightener drive.
