The invention relates to a reversible belt tightener for tightening a belt strap (13) of a safety belt which is wound around a belt reel (12) in a motor vehicle. Said belt tightener has a drive device (16) which acts on the belt reel (12). The safety belt has a blocking device (10, 11) which acts on the belt reel (12) in the unreeling direction, blocking the drawing out of the belt. According to the invention, following the triggering of the belt tightener and in the presence of a predetermined condition, said belt tightener is controlled in such a way that the belt reel (12) turns at least so far in the reeling up direction (B) that the blocking device (10, 11) of the belt reel (12) opens and the releases the belt strap (13) for unreeling.

The invention relates to a method for controlling a reversible belt tensioner for tensioning a belt strap, which unwinds from a belt retractor, of a safety belt in a vehicle. The belt tensioner comprises a drive that acts upon the belt retractor, and the safety belt comprises a blocking device, which serves as a belt withdrawal stop and which acts upon the belt retractor in a direction of unwinding. The blocking of said blocking device can only be released when the belt retractor is rotated around a defined angle of rotation in the direction of winding. After the release of the belt tensioner prompted by a dangerous situation and in the existence of a predetermined vehicle operational state, which is indicative to an end of the dangerous situation, the drive of the belt tensioner is controlled in an opening mode in order to open the blocking device. The drive is controlled in such a manner that, firstly in a winding phase, the belt retractor rotates around the defined angle of rotation in the direction of winding. In a subsequent holding phase, the drive of the belt tensioner is controlled for a predeterminable holding time TH whereby holding the belt retractor in its angular position.

The invention relates to a method for actuating a reversible belt pretensioner for tensioning a belt strap of a safety belt, which reels off from a belt reel, in a motor vehicle. According to the present invention, said belt pretensioner comprises a drive, which acts on said belt reel and the safety belt comprises a blocking device which acts on said belt reel in the unreeling direction, blocking the drawing out of the belt. The blocking of said blocking device can only be released when the belt reel is turned to a specified rotation angle in the reeling direction. After a triggering of said belt pretensioner, conditional on a dangerous situation and when a value, indicative of the force applied upon the belt, indicates a diminution of said force, an opening mode is initiated. In said mode, the belt pretensioner drive is actuated for opening said blocking device, such that, at the beginning of said opening mode, the belt reel is turned to a specified rotation angle in the reeling direction.

The invention relates to a method for moving a headrest of a vehicle seat in the event of a rear-end collision and to an arrangement of a headrest on a vehicle seat. According to the invention, the headrest (3), in the event of a rear-end collision, can be moved in a forward direction of travel (Y) by means of a drive device (4) and by an impact device (5) that absorbs a rearward movement of the upper body of an occupant located on the vehicle seat (1).

The invention relates to a method for actuating a reversible passenger protection system in a motor vehicle comprising a driving state sensor and a reversible passenger protection system. Said reversible passenger protection system can be unlocked before a collision and therefore be placed in an actuating position. The driving state data is monitored in relation to an emergency braking situation, and if an emergency braking situation is identified, the passenger protection system is actuated. The data processing device also determines an oversteering situation and an understeering situation. If the data processing device identifies an emergency braking situation and/or an oversteering situation and/or an understeering situation, the reversible passenger protection system is actuated.

摘要:
The invention concerns a method for controlling the operation of a reversible belt retractor and release a belt-unwinding lock activated by an acceleration sensor, on a safety belt provided in a motor vehicle. The belt retractor being interlocked in response to a dangerous condition and said dangerous condition being perceived as being over, the operation of the belt retractor is controlled by a release signal at a releasing time, so as to release the lock unwinding the belt and shift it from a locked condition to a comfort-providing condition. The invention is characterized in that the release time is determined by means of a sensor model algorithm based on an acceleration sensor model, from at least one measurable quantity characteristic of the running dynamics.
