Abstract: The inertia sensor is a sensor for a seatbelt retractor used for sensing deceleration. The inertia sensor is composed of a primary mass, a secondary mass, and a lifter. The primary mass provides the inertia for the self compensating function. The secondary mass provides the inertia for sensing deceleration. The inertia sensor is not triggered when subjected to tilting angles of 30 degrees or less in any direction. Upon experiencing decelerating motion, the secondary mass tilts relative to the primary mass whereby this relative angular displacement causes the lifter to raise. The lifter rotates a locking pawl into an engagement position, which initiates the locking mechanism of the seatbelt retractor.

Abstract: A vehicle seat belt system, in particular a three-point seat belt system, has belt webbing and an end fitting by which an end of the belt webbing is secured to a vehicle. A belt tensioner acts with a pulling eyebolt through which the belt webbing is guided by a webbing guide in the vicinity of the end fitting to transmit a tensioning movement to the belt webbing. The pulling eyebolt has a substantially straight pulling rod by which a pulling movement generated by the tensioning drive is transmitted to the belt webbing during tensioning and during tensioning the pulling rod acts as a webbing deflection rod for the belt webbing guided through the webbing guide. The webbing guide has two deflection points about which the belt webbing is guided during tensioning and the pulling rod acts on a section of the belt webbing guided between these two deflection points.

Abstract: The load acting on the body of a belted-in vehicle occupant restrained by a seat belt is determined by providing electrical signals from occupant restraint device sensors. The electrical signals are then evaluated with an evaluating device, wherein the movement of a seat belt webbing influenced by the body of the belted-in vehicle occupant is scanned and a corresponding signal is fed to the evaluating device.

Abstract: A device for the lateral outward guiding of an electric cable installed in a tube has a deflector is arranged inside the tube obliquely to the longitudinal direction of the tube. The electric cable is deflected by the deflector through a lateral opening in the casing of the tube.

Abstract: Energy is conserved utilizing information collected by a vehicle safety system. Information concerning whether seats other than the driver's seat are occupied and information concerning the size and weight of any occupants present, is transferred to a power load logic via a vehicle information data bus, or by a hard wired communication link. Power is conserved by turning off energy consuming functions which are specific to an unoccupied seat, or by modulating power consuming functions in proportion to the size and weight of the seat occupant.

Abstract: A steering wheel comprising: a rim (24) and a hub member (22) and a plurality of spokes (26a-d) interconnecting the rim and hub member configured to have a first polar moment of inertia; the rim including a hollow space (43) and an insert (50) received within the hollow space, the rim and the insert configured to raise the effective polar moment of inertia of the steering wheel from the first polar moment to a level to reduce any shimmy of the steering wheel.

Abstract: A seat belt retractor has a housing and a spool in the housing. A toothed ratchet wheel is coupled to the spool. A locking assembly has a lock bar pivotally mounted to the housing and moveable by means of a camming arrangement from an initial position clear of the ratchet wheel to a position whereby the lock bar locks the ratchet wheel to the housing. An adjustment mechanism enables adjustment of the initial position of the lock bar.

Abstract: A seat belt pretensioner has a piston; a tube housing the piston; a force reservoir, activatable when a crash is sensed, to drive the piston along the tube; a resilient steel band connected to the piston; and means for selectively connecting the steel band to a retractor spool. Preferably the force reservoir is a gas generator which may be pyrotechnically activated and has an output in the tube on one side of the piston to drive the piston along the tube pulling the steel band and engaging the connecting means to turn the retractor spool and shorten the belt webbing. The steel band has indexing features, such as indexing holes or slots to engage teeth on the outer periphery of a drive wheel attached to the retractor spool. As the steel band is pulled by the piston it tightens around the drive wheel and the indexing holes engage the teeth, turning the drive wheel and thus the spool and pulling in the webbing to secure the vehicle occupant.

Abstract: A linear pretensioning drive for tightening a vehicle seat belt has a guide tube. A piston is located inside of the guide tube and can be driven along a longitudinal axis of the guide tube. A reverse movement lock is formed by balls that are arranged on a ring around the longitudinal axis of the guide tube. In the drive direction in front of the reverse movement lock at least one support part is provided which lies against the inner wall of the guide tube in the locking position with in each case a greater supporting surface than each ball of the reverse movement lock.

Abstract: A seat belt retractor has a spool mounted for rotation on the retractor frame, for retraction or pay-out of seat belt webbing depending upon the rotation direction of the spool. The spool is locked against rotation when a crash is sensed. A force limiting mechanism allows further pay-out of the seat belt webbing after the spool shaft has locked, under the influence of a vehicle occupant's forward momentum. The force limiting means includes a torsion bar attached in the force path between the spool and its axis of rotation; and a resilient mechanism. A mechanism selectively connects the resilient mechanism into the force path between the spool and its axis of rotation. A selecting mechanism selectively activates the connecting means in response to a control signal.

Abstract: A seat belt retractor has a spool mounted for rotation in the retractor for retraction or pay-out of seat belt webbing depending upon the rotation direction of the spool. A locking ring is attached to one end of the spool. A lock bar locks the locking ring against rotation when a crash is sensed. A load limiter allows further pay-out of the seat belt webbing after the spool has locked under the influence of a vehicle occupant's forward momentum. The load limiter is a torsion bar attached at one end to the locking ring and at the other end to the spool; and a wire releasably coupled in the force path between the spool and the locking ring. The resilient mechanism, i.e. the wire, decouples itself after a predetermined number of turns of the torsion bar. The thickness, length and composition of the wire, together with the number of wires may be chosen to suit a vehicle's crash criteria.
