Abstract: A belt retractor for a seatbelt comprising a retractor pawl which blocks the seatbelt from being pulled out of the belt retractor in the event of an accident, and having a tightening device which tightens the seatbelt in a hazardous situation, the tightening device includes a tightening pawl which, in a blocking position, blocks the belt retractor in the belt uncoiling direction and, in a release position, leaves the belt retractor unaffected. The tightening pawl is assigned a sensor which monitors the position of the tightening pawl and transmits a signal indicating the position of the tightening pawl to a control device of the tightening device.

Abstract: A belt retractor for a seat belt includes a belt reel, an eccentric disc connected to the belt reel, a cam disc driven by the eccentric disc, and a blocking pawl. The blocking pawl, in a blocking position, blocks a toothed ratchet wheel, and, in a release position, leaves the toothed ratchet wheel unaffected. The blocking pawl may be switched from the release position into the blocking position and conversely from the blocking position into the release position with the cam disc. For the belt retractor to be independent of tolerances, provision is made for the cam disc to have an engaging cam for engaging the blocking position of the blocking pawl and a disengaging cam for engaging the release position of the blocking pawl.

Abstract: A safety belt apparatus for motor vehicles. The apparatus includes a safety belt and a belt tensioner which can be mounted to the vehicle in the region of a free belt section and which cooperates with the safety belt in the region of the free belt section to alter the effective length of the safety belt.

Abstract: A belt reel has a spindle having a main body portion and a relatively rotatable end member that can be latched to a fixed frame upon triggering of an activation device. The main body portion of the spindle is formed with a bore which is filled with hydraulic fluid. The spindle further includes a force-limiting element which cooperates with the hydraulic fluid in the bore to produce a resistance against which the spindle body must be rotated when the relatively rotatable end member is latched to the frame.

Abstract: An airbag arrangement for a motor vehicle includes an airbag deployable in a direction to protect a vehicle occupant and an arrangement for limiting the unfolding impulse of the airbag upon an obstacle placed in a deployment path of the airbag to reduce the unfolding impulse transferred to the obstacle. The limitation arrangement, which can be, for example, a sheath, aperture in the airbag, can respond to the resistance of the occupant located in the deployment path, which is outside a normal seating position, or respond to a lack of resistance from the passenger. As the limitation arrangement limits the unfolding impulse of the airbag, it reduces the maximum unfolding impulse transferable to the occupant located outside the normal seating, in the deploying path.

Abstract: A belt-buckle tightener for a seat belt system in a vehicle, having: a rotatable spindle which is connected to a belt buckle via a draw-in cable; and a drive for rotation of the spindle, as a result of which the draw-in cable is rolled up on the spindle and the belt buckle is moved in the tightening direction, and the drive being integrated in the spindle. Integration of the drive in the spindle reduces the structural space required. In addition, the number of individual parts which are required is reduced since, inter alia, a separate driving spindle is not required. Rather, the spindle for winding up the draw-in cable at the same time forms the driving spindle.

Abstract: A seat belt device is provided. The seat belt device has a seat belt roller together with a locking device for locking the seat belt roller. The seat belt device furthermore has a guide pin which is moveably supported inside a guide link and is coupled to the locking device. The displacement of the guide pin inside the guide link depends on the direction of movement of the seat belt roller. The coupling of the pin to the locking device provides that locking of the seat belt roller is either brought about or prevented, according to the positioning of the guide pin in the guide link. The seat belt device makes it possible to ensure that seat belt locking is activated only when unreeling, and not when the set belt is being reeled in.

Abstract: A passenger safety device in which an airbag is disposed in the roof area of the vehicle, especially in the area of the roof rail of the vehicle, and in which the airbag of the airbag is stowed at least partially rolled up in the passenger safety device.

Abstract: A drive for a belt tensioner for safety belts has a drive chamber formed between two plates. A drive band whose two ends are fastened to a drive shaft such that the drive band forms a loop which can be exposed to expanding gas discharged from a gas outlet such that the drive band winds off and drives the drive shaft. The drive band is fixed to the plates by a fixing apparatus at a position disposed between its ends.

Abstract: A safety belt apparatus for vehicles, in particular motor vehicles having at least one safety belt, which is wound to a greater or lesser degree onto a belt reel rotatably secured on the vehicle chassis about an axis of rotation and preferably biased by a spring retraction mechanism. A toothed ratchet wheel is rotationally coupled to the belt reel and cooperating with a blocking pawl secured to the housing. The blocking pawl is movable into and out of engagement with respect to the toothed ratchet wheel by a cam ring concentric to the belt reel axis via a step down transmission. A toothed control wheel is connected to the belt reel via an eccentric transmission and has at its periphery a preferably wavelike arrangement of teeth which is surrounded by an inner toothed ring fixed to the housing of larger diameter and with complementary, but with a smaller or preferably larger number of teeth.

Abstract: A safety system for occupants of motor vehicles that includes a safety shoulder belt and an air bag module for lateral protection of the head and thorax areas of the occupants. The air bag module includes an air bag which has an area that protects an occupant's thorax and an area that protects an occupant's head. The area for the protection of the thorax includes an upper section. The area for the protection of the thorax a least extent rearward in the upper section where the safety belt also runs. The area for protection of the head is configured to extend substantially above the shoulder belt and further rearward than the upper section of the area for protection of the thorax.

Abstract: A vehicle has an airbag arrangement for protecting the occupant from neck whiplash during a front or rear collision and the cervical spine during a vehicle roll over. The airbag arrangement has an airbag device integrated with the vehicle seat. The airbag device has at least one airbag for protecting the occupant's head/neck region. The airbag is fully inflated when the vehicle rolls over. In that state, the airbag projects from the vehicle seat in such a way that it actively bends the occupant's head toward the occupant's chest, i.e., rolls the upper body for better protection. During a front and rear collision without a roller over, however, the airbag only partially inflates to an extent to position the airbag between the occupant's head and the head restraint, without displacing the occupant's head with the airbag.
