The disclosed seat belt tensioner for a seat belt system may comprise a seat belt spindle, a gearwheel connected to the seat belt spindle, and a latching pawl for locking the seat belt spindle in the tensioned position by engaging in the teeth of the gearwheel. The latching pawl may be configured to be brought into a first pawl position for blocking the gearwheel in the seat belt unrolling direction and into a second pawl position for blocking the gearwheel in the seat belt-tensioning direction of rotation. The latching pawl may also be configured to perform a first pivot-over operation from the first pawl position into the second pawl position and to perform a second pivot-over operation from the second pawl position into the first pawl position when the gearwheel exerts a force on the latching pawl that exceeds a predetermined force required for the respective pivoting-over operation.

Seat belt tensioner

The disclosed seat belt tensioner is for a seat belt safety system that may comprise a seat belt spindle, a drive motor for driving the seat belt spindle, and a gear connected to the drive motor. The gear may be a mechanical automatic gear that shifts automatically as a function of load

The disclosed seat belt tensioner may comprise a drive motor, a gear connected to the drive motor, and a seat belt spindle connected to the gear by a spindle clutch. The spindle clutch may have spindle clutch pawls, which engage in pawl teeth of the seat belt spindle to couple the seat belt spindle and the gear. The spindle clutch may also comprise a synchronization pawl configured to alit the pawl teeth before the spindle clutch pawls engage in the pawl teeth.

The invention relates to an airbag arrangement in vehicles, which is preferably secured at the steering wheel ( ) of the vehicle and which comprises a gas generator ( ) which is secured to a generator carrier ( ) and which can be ignited in the event of an accident, an inflatable gas bag ( ) which is at least largely tightly connected to the latter via an opening ( ), which is folded together and which can be inflated by the gas from the gas generator ( ), and securing means ( ) for the edge ( ) of the gas generator ( ) surrounding the opening ( ) which are attached to the vehicle, in particular at the steering wheel ( ). The invention consists in that the gas generator ( ) is attached in a resiliently yielding manner at least in one direction, preferably in all directions at least substantially perpendicular to the central axis ( ) of the gas generator ( ) or the generator carrier ( ) or, respectively, of the steering column independently of the securing means ( ) for the gas bag ( ).
