A torsion shaft for a seat belt retractor assembly, the torsion shaft being connectable at a first location to a spool for receiving a seat belt and connectable at a second location to a locking mechanism, the first and second locations being spaced apart along a length of the torsion shaft, wherein the torsion shaft is configured to deform when a torsion force is applied between the first and second locations during an impact event, wherein the torsion shaft comprises a cavity and a fluid is provided in said cavity so as to support the torsion shaft as the torsion shaft deforms during the impact event.

A safety system includes a restraint configured to secure an occupant to a seat, an anchor coupled to the restraint and movable along an anchor guide, an anchor energy-absorbing (EA) device configured to control movement of the anchor along the anchor guide, and a controller that includes a processor configured to receive information indicative of an imminent vehicle event, receive information indicative of a recline angle of the seat being above a recline threshold, and send a command to enable the anchor to move along the anchor guide under control of the anchor EA device based on the information indicative of the imminent vehicle event and the recline angle being above the recline threshold.

A safety belt automatic adjustment apparatus includes a safety belt buckle fastening assembly, a safety belt retractor and a linking component. The safety belt buckle fastening assembly is rotatably connected to a seat body of a child safety seat and for connecting with a safety belt buckle. The safety belt retractor is used for retracting a safety belt, and the safety belt retractor includes a restraining assembly for restraining a movement of the safety belt in a predetermined direction. The linking component is installed between the safety belt buckle fastening assembly and the safety belt retractor, and the safety belt buckle fastening assembly rotates to drive the linking component and the restraining assembly, so as to restrain or release the safety belt winding around the safety belt retractor. The safety belt automatic adjustment apparatus has advantages of automatic adjustment for the safety belt, simple structure, convenient operation and enhanced safety.

The invention relates to a belt retractor comprising a frame (10), a belt reel (12) rotatably arranged within the frame (10), a blocking mechanism (18) by which the belt reel (12) can be blocked within the frame (10), and a load limiter which comprises a corrugated disk (36), characterized in that the corrugated disk (36) is disposed between the belt reel (12) and a cover (38) which is laterally attached to the belt reel (12).

The invention relates to an actuator (70) for releasing a load limiter (14) of a belt retractor for a vehicle seat belt, comprising a case (72) which is adapted to be attached to a frame (10) of the belt retractor and includes a seat (82) in which a pyrotechnical actor (80) is arranged, characterized in that a retaining clip (90) for locking the actor (80) within the seat (82) is attached to the case (72). The invention further relates to a belt retractor comprising a frame (10), a belt reel (12) rotatably supported in the frame, a load limiter (14) which is detachably connected to the belt reel (12) and an actuator (70) of the afore-mentioned type, characterized in that the retaining clip (90) bears on the frame (10).

A seatbelt device for a vehicle comprises a belt which restrains an occupant, a retractor which supports the belt so as to wind up one end of the belt, a frictional-force applier which is configured to apply a frictional force to the belt by contacting the belt, and an actuator to actuate the frictional-force applier so as to change the frictional force.

A torsion shaft for a seat belt retractor assembly, the torsion shaft being connectable at a first location to a spool for receiving a seat belt and connectable at a second location to a locking mechanism, the first and second locations being spaced apart along a length of the torsion shaft, wherein the torsion shaft is configured to deform when a torsion force is applied between the first and second locations during an impact event, wherein the torsion shaft comprises a cavity and a fluid is provided in said cavity so as to support the torsion shaft as the torsion shaft deforms during the impact event.

A device for influencing the force of a seatbelt acting on an occupant of a passenger vehicle during a collision, for example. The device includes a rotary damper with a magnetorheological fluid as a working fluid for damping a rotational movement of a damper shaft of the rotary damper when winding or unwinding the seatbelt. The rotary damper has a displacing device with displacing components which engage into one another and which are wetted by the magnetorheological fluid. By using a paired controller, a magnetic field of a magnetic field source with an electric coil can be controlled and the magnetorheological fluid can be influenced in order to adjust the damping of the rotational movement of the damper shaft.

An energy absorbing seat belt retractor used with a seat belt assembly of a motor vehicle. The seat belt retractor includes a reel for winding and unwinding the seat belt and an elongated shaft, with the reel attached to the shaft. In one example, a movable disc is connected to and moves longitudinally along the shaft. At least one of the reel or movable disc includes a friction layer providing a friction surface such that when the movable disc is driven axially toward the reel there is frictional engagement between the reel and movable disc that absorbs impact energy on the occupant and limits the load applied to the seat belt.

A webbing take-up device that includes a spool that is rotated in a take-up direction to take up webbing worn by an occupant and that is rotated in a pull-out direction by the webbing being pulled out, and a frame that rotatably supports the spool. The frame includes a fixed stay portion that is fixed to a vehicle body, and a rotation stop stay portion that is disposed spaced apart from the vehicle body and that by being engaged with the vehicle body is restricted from rotational displacement relative to the fixed stay portion.
