Safety belt system has an automatic roll-up device and a sensor device which effects locking of the belt in the automatic roll-up device when a predetermined deceleration is exceeded. In combination, the safety belt system has an electric safety current circuit connected to the battery to provide current to energize actuating means which effect locking of the belt in the roll-up device, a switch is provided in the circuit operable by the steering wheel lock. Another switch in the circuit is triggered by the sensor when deceleration is exceeded.

Retightener with a pyrotechnic propellant charge for automatic safety-belt wind-up devices having an energy converter, wherein in the event of danger the explosive pressure of the ignited propellant charge acts on a pullout element tightening the safety belt around the body of the vehicle passenger to be protected via a liquid buffer arranged between the propellant charge and a pullback element. In accordance with the invention a receptacle which contains the liquid buffer is coupled to the winding shaft and rotates together with the latter. In the circumferential surface of the receptacle is at least one jet nozzle directed substantially tangentially to the axis of rotation and against a stationary guide ring surrounding the receptacle.

Lock for motor vehicle safety belts with a metallic base plate which has a recess in which a latching mechanism is supported so that it can be swung about an axis extending transversely to the insertion direction of a plug-in blade from the closed position by a pushbutton against the action of a spring. With insertion of the plug-in blade the locking mechanism snaps with a latching projection into an undercut of the plug-in blade to the closed position. The recess in the base plate is formed by punching free a lug, which bent out of the plane of the base plate is unitary with and spaced from the base plate forming a guide for the plug-in blade. Manufacture of such locks is simpler with savings in material. In addition the locks are lighter in weight.

A closure, or latch, especially for passenger seat belts in which a housing on the end of one belt portion has a slot for reciving a tongue on a member on the other belt portion. Within the housing are roller bodies engaging each other and spring biased toward the tongue. The tongue is provided with notch means for engagement by a roller body to effect latching while a disengaging member moveably carried by the housing is operable for moving the roller bodies into disengaging position.

A roller system for a safety belt with a winding-up shaft coupled to a return spring and connected to a belt end while being journalled in a housing, the roller system also comprising a locking mechanism. The winding-up shaft or a compensating sleeve arranged thereon has its outer contour within the region of its connection with the belt so designed that the belt when being wound off or on describes the path of an Archimedes spiral.
摘要:
A winding-up device for a safety belt, in which a spool to which one end of the belt is connected is journaled in a housing with a spring biasing the spool in take-up direction. The belt can be freely drawn outwardly from the housing up to a limit acceleration. When a limit acceleration is reached, an inertia device interposed between the spool and the housing engages and prevents further rotation of the spool in the housing in pay-out direction.
摘要:
A device for blocking the shaft of a safety belt mechanism in which the blocking of the shaft is initiated in response to acceleration of the shaft in pay-out direction. An inertia responsive disc element is mounted on the shaft and movement thereof on the shaft initiates blocking of the shaft. To augment the inertia effect a magnet adjacent the disc provides a retarding effect thereon by the magnetic field from the magnet or by eddy currents in the disc induced therein by the field.

A device for attaching a steering wheel on a steering shaft by a connecting sleeve, which is attached to the hub of the steering wheel. At its end, the steering shaft has a section with exterior splines, which are complementary to interior splines in the connecting sleeve. The connecting sleeve has an axial slot and is clamped by a clamping screw against the section of the steering shaft which has the splines. The steering wheel constitutes a sub-assembly with an integrated air bag module and may be supplied for the final assembly of the vehicle.

A vehicle seat for a vehicle occupant has a backrest, a headrest arranged adjustable on the backrest and being movable from a normal starting position into a restraint position approximating the head of the vehicle occupant, a vehicle-sensitive activatable positioner and a flexible traction transmitting means connecting the headrest and the positioner. The positioner moves the headrest in the case of a rear end collision of the vehicle from the normal starting position into the restraint position by transmitting force via the traction transmitting means. The traction transmitting means extends through the backrest.

The coupling between the belt drum of a belt retractor and a belt pretensioner rotary drive renders possible the manufacture of the functional parts of a metallic light constructional material such as a light alloy. The belt drum (12) possesses a molded externally toothed coupling wheel (16). With the output shaft (20) of the belt pretensioner rotary drive (18) a drive disk (22) is connected, which bears two pivotally mounted coupling pawls (28). In a neutral or rest position thereof these coupling pawls are held by a return spring clear of the periphery of the coupling wheel (16) and may be pivoted inward into an engagement position in engagement with such coupling wheel.
