Abstract: A belt tensioner for a safety belt retractor has a housing, a piston which is displaceable in the housing, and teeth, which are arranged separated and spaced from the piston.

Abstract: A belt tensioner for a safety belt comprises a housing in which a piston is displaceable, and an exit port, wherein the exit port is arranged in the wall of the housing.

Abstract: A belt retractor comprising a tensioning device having a cylinder and a piston displaceably guided in said cylinder, said piston being provided with a tooth rack section into which a pinion can engage to drive said belt retractor, wherein said tooth rack section comprises at least one segment which is detachably attached to said piston.

Abstract: A safety belt system for a motor vehicle includes a belt retractor (10). The belt retractor (10) includes a belt spool (14) and an electric motor (18). The belt spool (14) can be rotated by the electric motor (18) at least in a belt webbing winding direction. According to a first aspect, the electric motor (18) is coupled to the belt spool (14) without a clutch, and the belt retractor (10) further includes a retraction spring (24) which pre-tensions the belt spool (14) in the belt webbing winding direction. The pre-tensioning force of the retraction spring (24) is restricted to functionality in terms of comfort. According to a second aspect, the electric motor (18) is controlled by a control unit (20) coupled to the braking system of the vehicle. A method for controlling an electric motor (18) in a safety belt system makes provision that the electric motor (18) is activated in response to a braking process.

Abstract: An ignition device for a pyrotechnic system in a motor vehicle includes an igniter and an interface unit (20) for the production of an electrical connection of the ignition device with a release system. The interface unit (20) is held in a housing (10) of the pyrotechnic system in a form-fitting manner without a further mounting.

Abstract: A belt spool, in particular for a belt retractor with belt tensioner, has a spool body. The spool body has a mounting at an axial end face. A pinion is arranged on the mounting.

Abstract: In a pyrotechnical drive (110) for a vehicle-occupant restraint system, has a cylinder (112), a piston (114) that is movably arranged in the cylinder, a pyrotechnical propellant charge (152) for generating pressurized gas, and an ignition charge for igniting the propellant charge. The piston has a thrust surface area (142) which can be acted upon with the pressurized gas in order to drive the piston (114). Between the ignition charge and the thrust surface area (142), a flow connection (F) is provided. In addition, a belt retractor (100) is described having a pyrotechnical drive of this type and a method for operating a pyrotechnical drive (110) of this type. In the method, the piston (114) is propelled over a first driving distance (Z1) by the gases generated by the combustion of the ignition charge (154) and is then propelled over a second driving distance by the gases generated during the combustion of the propellant charge (152).

Abstract: A belt retractor for a vehicle safety belt comprises a frame, a belt reel rotatably mounted in the frame, at least a first and a second energy-absorbing element, which each has a connecting end and a locking end, wherein the locking ends each are provided with a locking disc and adapted to be selectively connected with the frame. The belt retractor further comprises a first and a second locking pawl which by means of at least one actuating device can each selectively be brought into engagement in one of the locking discs, wherein at least one switching device is provided which can selectively prevent the engagement action of at least one locking pawl.
