The invention relates to a load-bearing seatbelt retractor for a seat structure of a vehicle seat, the seatbelt retractor having two housing halves between which functional modules of the seatbelt retractor are disposed. One functional module is a belt reel having a winding axis. The two housing halves form two mutually parallel receptacles in the seatbelt retractor, which are oriented perpendicular to the winding axis. Two seat bars can be inserted into the receptacles. The two housing halves are in contact at least on two contact lines above and below the functional modules with respect to an insertion direction of the receptacles. The lower contact line splits open on both sides along the winding axis such that respective intermediate spaces open toward the receptacles are formed.

Load-bearing seatbelt retractor and seat structure

A belt retractor comprising a belt reel rotatably mounted in a frame securable to a vehicle and on which a seatbelt can be wound, and a blocking device arranged on a mechanical side of the belt reel and which blocks the belt reel when a specified seatbelt pull-out acceleration and/or a vehicle deceleration is exceeded, activating the blocking device in the pull-out direction of the seatbelt, and an electric motor for rotating the belt reel, and a gearing mechanism which transmits the rotational movement from the electric motor to the belt reel, wherein the electric motor and gearing mechanism are arranged coaxial to the rotational axis of the belt reel and in series relative to the belt reel; and a transfer rod is provided arranged coaxial to the rotational axis of the belt reel and in series with the belt reel.

Belt retractor

The present invention relates to a belt retractor comprising a belt shaft which is rotatably mounted in a housing and onto which a safety belt can be wound, the housing being able to be fastened to the vehicle, and an electric motor for driving the belt shaft to move rotationally, and a gear mechanism transmitting the rotational movement from the electric motor to the belt shaft, wherein the gear mechanism can be driven as an assembly in a first force-transmission path to drive the belt shaft with a first torque, and the gear mechanism can be driven to drive the belt shaft with a second torque, by shifting a speed-controlled and/or torque-controlled coupling, whereby a second force-transmission path is opened, wherein the coupling has at least one coupling element which is spring-loaded by a spring into engagement in a first part of the gear mechanism.

A belt retractor having a belt reel, a safety belt which can be wound thereon to form a wound belt, a pyrotechnic belt tensioner having a drive device which is guided in a tube and can be driven to perform a drive movement, and at least one first further assembly arranged coaxially to the rotational axis of the belt reel and in series with the belt reel, a safety belt which can be wound thereon to form a wound belt, and at least one first assembly, wherein the tube has a straight linear section which extends parallel to the rotational axis of the belt reel and the longitudinal axis of the assembly and is arranged on the side of the belt reel.

The present invention relates to an airbag apparatus for a vehicle seat, comprising

Airbag apparatus for a vehicle seat and vehicle seat having an airbag apparatus

A quick-release fastener for a vehicle seat belt () with a fitting part (), and a fastening part (). The fitting part () has a first opening (), and a second opening (), in which the fastening part () can be locked to a locking head (). The fastening part () can be inserted into the opening () in which a spring element () is arranged in an assembly position (I), and the spring element () can be moved into the locked position (II). A housing () is adapted to the shape of the fitting part () with the locking head () retained therein. The mounting () is shaped n such that the fitting part (I) with the locking head () can be completely received in the mounting () only when the locking head () is in the locked position (II).

Quick-release fastener for one end of a seat belt fastened to a vehicle in a motor vehicle

A quick-release closure for a vehicle-mounted end of a seat belt in a motor vehicle having a fitting part, and a vehicle-mounted attachment part. A first opening is provided in the fitting part, in which one end of the seat belt can be attached by means of a loop which is guided through the first opening. A second opening is provided, in which the attachment part can be locked to a locking head. In the second opening a spring element is provided that can be moved from a mounting position) into a locking position. The locking head of the attachment part can be inserted into the opening in which the spring element is arranged in the mounting position, and the spring element can be moved into the locking position by a relative movement of the locking head with respect to the fitting part, securing the locking head in position.

Quick-release closure for a vehicle-fixed end of a seat belt in a motor vehicle

A restraining system for a motor vehicle with a seat belt retractor that accommodates the one end of a seatbelt component, which has a tightening device having a belt shaft and a drive cable connected to the belt shaft, in which a sleeve () that enlarges the outer circumference of the shaft element (25) is slid onto one end of the shaft element () and is axially and radially fixed to the shaft element (), while the wall thickness of the sleeve () is dimensioned in such a way that the drive radius of the shaft element () and a reduction in speed of the tightening drive is provided as compared with a cable wrapped onto the belt shaft.

Retaining system with seat belt retractor and pretensioner device

A tensioning device for a seatbelt system in motor vehicles with a driving arrangement that comprises a tube having at least one tube section bent with a radius of curvature, and a piston guided movably in said tube, whereby the piston is connected via a driving cable to the part of the seatbelt system which carries out the tensioning movement, and whereby the piston can be moved in a longitudinal movement through the tube by means of a pyrotechnic drive, and the driving cable is fixed to the piston by means of a holding part held by the piston. The piston () is configured in the form of an olive with a larger radius in the longitudinal direction of the tube () than the effective radius in the transverse direction of the tube () and is provided with a bore () for passing through the driving cable () that is held in a compression sleeve () fixed on the side of the piston () that points in the direction of movement of the piston ().

Tensioning device for seatbelts with an olive-shaped piston

The inventive device for fixing a seat belt winder is fixed to the part of a motor vehicle. The plate of the housing of the winder is provided with at lest one fixing hole for receiving a screw connection which maintains the vehicle part embodied therein. The housing of said seat belt winder is arranged in such a way that it is rotatable with respect to the fixing hole of the vehicle part, thereby enabling the winder to be automatically oriented in a direction of a force of a belt which moves at an angle with respect to the axis of the shaft. Said fixing device is characterised in that the housing () of the winder is rotationally maintained on the holder part () which can be firmly connected to the vehicle part (). Said housing () is supported by the holder part () at a distance to the fixing hole () of the vehicle part () and is fixed to said holder part () in such away that the housing () of the seat belt winder is rotatable with respect the holder part () in an opposite direction to the action of a pre-set resistance.
