The present invention relates to a safety belt retractor, including a bracket, a spool, a locking device, a vehicle sensing device (20) and a vehicle sensing suppression device, wherein the vehicle sensing suppression device includes a driven part and a suppression part. The driven part can be driven by the spool. The suppression part can be held on the driven part by an adhesive force, wherein the driven part has a sliding track, and the suppression part has a sliding portion that can slide on the sliding track against the adhesive force. The suppression part can be limited in a first end position, in which it can suppress the vehicle sensing function of the vehicle sensing device, and it can release the vehicle sensing function of the vehicle sensing device when leaving away from the first end position. Here, the mechanism for achieving the function of suppressing the vehicle sensing noise is simple in structure and low in cost, and can effectively reduce the vehicle sensing noise. The present invention further relates to a safety belt assembly including such a safety belt retractor.

The present invention relates to a safety belt retractor, including a bracket, a spool, a locking device, a vehicle sensing device with an adaptive vehicle sensing function and a vehicle sensing adaptivity suppression device. The vehicle sensing adaptivity suppression device includes a driven part (8) and a suppression part (7) that can be held on the driven part by an adhesive force. The driven part has a sliding track, and the suppression part has a sliding portion which can slide on the sliding track against the adhesive force. The suppression part has a retainer, and a sensing seat has a counter retainer that cooperates with the retainer. A retaining connection isn't formed when the suppression part is in the first end position, and is formed when the suppression part leaves away from the first end position to a predetermined extent. Here, the mechanism for achieving the vehicle sensing adaptivity suppression function is simple in structure and low in cost, and can effectively suppress the adaptivity of the vehicle sensing function. The present invention further relates to a safety belt assembly comprising such a safety belt assembly.

A seatbelt pretensioning retractor assembly for use in a passenger vehicle is provided. The pretensioning assembly includes a tube in fluid communication with a gas generator and a driving element disposed therein that travels in a first direction in response to actuation of the gas generator. The driving element includes a polymer rod. A stopper is coupled to an end portion of the polymer rod. In one example, a seal member is disposed between the gas generator and the stopper. In another example, the tube has an opening that is adjacent to an exit to facilitate venting gas from the gas generator.

A system includes a seatbelt retractor having a spool and a braking claw selectively engageable with the spool. The system includes an actuator designed to inhibit engagement of the braking claw with the spool. The system includes a processor and a memory storing program instructions executable by the processor to actuate the actuator to inhibit engagement of the braking claw with the spool for a threshold amount of time after detecting an impact of a vehicle.

The invention describes a belt retractor for a vehicle seat belt comprising a belt reel (12) supported for rotation in a frame, a sensor (16) for vehicle-sensitive blocking of the belt reel (12) and a mechanism (17) for disabling the sensor (16). Via a gear (18) supported for rotation on the frame and a cam follower (22) the belt reel (12) acts on the mechanism (17) for disabling the sensor (16) and can adjust the same.
