The invention relates to a belt reel () for a seat belt of a vehicle, said reel comprising a plastic base body () with a receiving chamber () that contains a belt strap pin () for securing a belt strap (). In said reel, a first end () of the belt strap pin () is directly supported on the base body () of the belt reel () and a second end () of the belt strap pin () is secured in a separate receiving part () that is attached to the base body ().

Belt reel

A belt retractor for safety belts of motor vehicles comprises a housing frame made of plastic for receiving a belt reel. The housing frameis designed an open, U-shaped frame, on the open front face of which a reinforcing platemade of plastic is fastened. In addition, a belt retractor for safety belts of motor vehicles comprises a housing frame of plastics material for receiving a belt reel. A pawl co-operating with the belt reel is mounted in the housing frame. The pivoting path of the pawl is limited by a bearing surface formed in the housing frame.

Belt retractor for safety belts

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.

Belt tensioner for a safety belt retractor

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.

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.

Belt retractor comprising a tensioning device

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.

Belt retractor for a vehicle safety belt

A belt retractor for a vehicular seat belt comprises a belt reel rotatably mounted in a frame, two locking discs for blocking the belt reel and two energy absorbing elements. The energy absorbing elements are each connected at an axial end to a locking disc and one of which is non-rotatably connected at an axial end to the belt reel. The belt retractor further comprises two locking pawls that are capable of cooperating with the locking discs. At least one of said locking pawls is releasably connected in a starting position to the frame by a connecting element.

Belt retractor for a vehicular seat belt

A belt spool for a belt retractor comprises a torsion rod and a spool body that has a recess in which is provided a shaped part by means of which an end of a safety belt can be fastened in the recess. The shaped part rests at the torsion rod in order to be supported when the shaped part is stressed by a tensile load of the safety belt. There is also proposed a belt retractor including such a belt spool.

Belt spool

A coupling disc for a belt retractor of a vehicle safety belt comprises a coupling catch which is pivotally mounted on the coupling disc so as to be movable between a position of rest and a coupling position. The coupling catch and the coupling disc are formed in one piece from plastic.

Coupling disc for a belt retractor of a vehicle safety belt

An assembly unit consisting of a belt retractor ( ) for a vehicle seat belt ( ) wound on a belt reel ( ) of the belt retractor ( ), a belt tensioner drive ( ) providing a drive energy by means of which the belt reel ( ) of the belt retractor ( ) can be driven in the winding direction, and a gearing ( ) coupling the belt tensioner drive to the belt reel is characterized in that the gearing ( ) provides a translation ratio which changes during a tensioning action.

Assembly unit consisting of a belt retractor and a belt tensioner drive

A belt reel for a belt retractor of a vehicle occupant restraint system comprises a cylindrical spool adapted for accommodation of a belt webbing and at least a first collar arranged at a first axial end of the spool. The spool consists of at least one sheet-metal sleeve, and the collar is formed by a sheet-metal disk.

Belt reel for a belt retractor of a vehicle occupant restraint system

The present invention relates to a belt system for restraining a vehicle occupant, comprising a safety belt, a belt buckle, two end fittings, at least one belt retractor, at least one inflatable belt gas bag and at least two belt tensioners. At least one of the belt tensioners is an end fitting tensioner.

Belt system for restraining a vehicle occupant

A load-bearing frame is provided with a fastener extension which is configured integrally with the frame and comprises a fastener opening for mounting the frame in a vehicle-fixed manner.

Load-bearing frame of metal for a vehicle seat belt buckle

A belt tensioner comprises a cylinder with an inner shell surface, a piston with a piston head, a working space in the cylinder into which compressed gas enters upon activation of the tensioner to drive the piston, a part engaging the safety belt, and a traction means attached to the piston and to the belt engaging part. The piston head delimits the working space and is formed by an annular sealing plate on which an essentially axially extending thin sealing lip is formed. The lip is adapted to resiliently yield radially and contact the inner shell surface of the cylinder in a biased condition.

Belt tensioner

A pyrotechnic means for vehicle occupant protection systems includes a container for an ignitor, propellant and/or compressed gas. To facilitate the production of gas tight pyrotechnic means having long term stability the container includes a container body and at least one container lid with an ultrasonic welded joint between said container body and said container lid.
