摘要： A seat belt pretensioner mechanism (40) includes a part (36) for attachment to the seat belt (20). A strap (50) is connected to the part (36). A piston (78) and piston rod (58) are movable in a first direction to move the strap (50) and the part (36) to tension the seat belt (20). A pivot connection (59, 62) between the piston rod (58) and the strap (50) causes the strap to move with the piston rod. A cam (70) pivots the strap (50) about the pivot connection (59, 62) and effects movement of the part (36) toward the piston rod (58) as the piston (78) and the piston rod move in the first direction.

摘要： An operating system and method for a vehicle safety device that includes a housing having a duct, one or more pistons in the duct and a gas generator that has two stages. The first stage is ignited conventionally, but the second stage is ignited automatically with a delay directly responsive to the first stage ignition. The gas generated is fed to a common space in the housing where it drives the piston(s). Each piston has an associated axially spaced thimble with a load limiter between. A cable is connected to each vehicle safety device and to each thimble. When the system is operated, each piston is driven to move its associated thimble away to draw the cable from the associated vehicle safety device to actuate it. However, if a counter force on the cable becomes excessive, the thimble moves closer to the piston and the excessive pressure is relieved under the control of the load limiter.

摘要： A seat belt tension sensor is attached to a seat belt in a vehicle. The seat belt tension sensor includes a housing attached between the vehicle and the seat belt. A limit structure is located in the housing. A sensor is attached to the limit structure for generating an electrical signal in response to the sensor being placed in tension. The electrical signal changes as a function of tension on the seat belt. The limit structure moves between a first position in which the limit structure transfers the seat belt tension to the sensor and a second position in which the limit structure transfers the seat belt tension to the housing.

摘要： A vehicle occupant safety system (10) for helping to protect an occupant (12) of a vehicle seat (14) during a crash condition comprises at least one sensor (174) for sensing a vehicle crash condition and generating a signal indicative of the crash condition. The vehicle occupant safety system (10) also includes seat belt webbing (20) for extending around the vehicle occupant (12) and a pretensioner (24). The pretensioner (24) is responsive to the signal generated by the sensor (174) for acting on the seat belt webbing (20) to pull an occupant (12) of the vehicle seat (14) who is forward in the seat (14) backward toward a back portion (18) of the seat (14). The pretensioner (24) comprises a seat belt retractor (26) that includes a spool (34) on which the seat belt webbing (20) is wound and an electric motor (108) for rotating the spool (34) in a belt retraction direction (172).

摘要： An assembly of seat belt buckle and a seat belt tightener has a seat belt buckle that is connected to a seat belt tightener by a pulling element. The pulling element is firmly connected within a buckle casing to a buckle mechanism of the belt buckle. The pulling element, in a region directly adjacent to the buckle casing is at least partly enclosed by a cover. The cover has an exterior shape that is tapered towards a direction in which the buckle is pulled during a seat belt tightening process. The external dimensions of the cover in the region of its larger cross section approximate the external dimensions of the adjacent end of the buckle casing and in the external dimensions of the cover in the region of its smaller cross section approximate to the external dimensions of the pulling element. Put another way, the taper of the cover approximates a taper defined by the external dimensions of an adjacent end of the buckle casing and the external dimensions of the cable over the length of the cover.

摘要： A new and useful belt-tensioning device for an occupant restraint is provided, designed to tension a belt (102) about an occupant at the onset of a vehicle collision, and to provide a measure of controlled force dissipation as the occupant loads the belt during the collision. In a preferred form, a tensioning member (122) moves in one direction (124) to tighten a belt about a vehicle occupant at the onset of a collision, and a braking device (130a, 130b) is configured to apply a controlled braking force to movement of the tensioning member in the opposite direction after the tensioning member has tightened the belt about the vehicle occupant. An array of braking members (130a, 130b) applies different levels of braking force to movement of the tensioning member in the opposite direction, thereby providing controlled braking force to movement of the tensioning member in the opposite direction.

摘要： An automotive seat safety mechanism includes a seat back and a webbing arranged between the seat back and a vehicle roof. A retractor urges the webbing in a winding direction while simultaneously permitting the webbing to be drawn out in an unwinding direction when in a normal state and prevents the webbing from being drawn out when acceleration of the vehicle becomes greater than a predetermined value. A bypassing mechanism is arranged above the seat back. A pretensioner is included in the retractor. The retractor is arranged above and rearward from the seat back. The webbing extends between an upper position of the seat back and the retractor bypassing the bypassing mechanism. The webbing is disengaged from the bypassing mechanism when forward acceleration becomes greater than a predetermined value. The pretensioner is activated to quickly draw in the webbing in response to the forward acceleration.

摘要： 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.

摘要： An end of a seat belt is connected to a part of the vehicle body via an actuator that can selectively remove a slack from the seat belt. The actuator includes a mass member attached to said moveable end of said seat belt, a main actuator unit adapted to move said mass member in a direction to remove a slack from said seat belt immediately upon detection of a frontal vehicle crash, and a cushioning member for decelerating a movement of said mass member following a certain initial travel of said mass member. The main actuator produces an early rise in the vehicle occupant deceleration, and the cushioning member smoothly connects the time history of the vehicle occupant deceleration to a ride-down condition whereby the deceleration acting on the vehicle occupant is favorably spread over time, and the maximum level of the deceleration can be minimized. The mass member contributes to a favorable shaping of the time history of the vehicle occupant deceleration.
