A vehicle with a vehicle seat arranged in the vehicle interior, which is paired with an occupant protection system, which has at least one crash detection sensor system that detects at least one acceleration value in the event of a crash, which influences the vehicle in the event of a crash so that inertial forces act on the vehicle seat connected to the vehicle and on the occupant sitting on the vehicle seat on the basis of an acceleration value, wherein the acceleration value is used for the crash-adaptive specification, over time, of said displacement travel of the occupant secured with a belt system on the vehicle seat. A total displacement travel of the vehicle seat in the travel direction comprises an additional, exclusively crash-active displacement travel adjoining a displacement travel of the vehicle seat for seat length adjustment in the travel direction.

In a vehicle emergency, rotation of a lock base in a pull-out direction opposite to a take-up direction is restricted. A first pinion-configuring portion formed at an outer circumferential portion of the lock base configures one width direction side of a pinion section that is rotated in the take-up direction by a rack that moves due to fluid pressure in a vehicle emergency. A coupling member disposed between the lock base and the torsion shaft is fixed to the lock base and to a torsion shaft. A second pinion-configuring portion that configures a width direction other side of the pinion section is formed alongside the first pinion-configuring portion at an outer circumferential portion of the coupling member.

A seatbelt pretensioning retractor assembly for use in a passenger vehicle is provided. The pretensioning assembly includes a one-piece tread head pinion including a ring portion having a plurality of teeth and a pair of flanges on each side of the teeth. The tread head pinion is formed as a single piece and includes a shaft extending from a side and a bearing portion extending from a second side. A bending element mounting portion extends from the bearing portion. The one-piece tread head pinion is attached to a spindle via a torsion bar, and the spindle bears against the bearing portion when the spindle rotates relative to the tread head pinion. The one-piece tread head pinion may include a staking cavity extending into the bearing portion with a staking wall that is deformable toward a digressive bending element inserted into the staking cavity.

A webbing take-up device includes a spool that takes up webbing worn by an occupant by being rotated in a take-up direction, and a pretensioner mechanism. The pretensioner mechanism includes a gas generator that includes a gas-generating-agent-storing portion and an ignition-device-storing portion, and a cylinder to which the gas generator is attached and that includes a second tubular portion into which gas generated by the gas generator is supplied. A discharge hole, through which gas supplied to the second tubular portion is discharged, is formed in a portion of the cylinder where the ignition-device-storing portion is disposed.

The invention describes an igniter support (22) for an igniter unit (20) of a gas generator (10), comprising a first holder element (30) made from a first material and a second holder element (32) made from a second material different from the first material. Both holder elements (30, 32) can be positively coupled to each other. Further, a subassembly (16), a gas generator (10) and a method for manufacturing a gas generator (10) are described.

The invention describes an igniter support (22) for an igniter unit (20) of a gas generator (10), comprising a first holder element (30) made from a first material and a second holder element (32) made from a second material different from the first material. The two holder elements (30, 32) can be positively coupled to each other, especially can be at least partially positively nested. Further, a subassembly (16), a gas generator (10) as well as a method for manufacturing a gas generator (10) are described.

The invention describes a vehicle occupant restraint device for the protection of a vehicle occupant (2) in a vehicle seat (6) comprising plural restraining elements and a controller, wherein at least one first restraining element comprises an airbag module (28) including an airbag (22) and at least one second restraining element comprises a seat belt (4) including a belt retractor, with the seat belt (4) being operatively connected with a tensioning unit. The controller includes at least one sensor element for determining the position of the vehicle seat (6) so that, in a situation of restraint, the controller differentiates between a first situation in which the vehicle seat (6) with the vehicle occupant (2) is in a position within the range of a standard position relative to the airbag (22) of the first restraining element, and a second situation in which the vehicle seat (6) with the vehicle occupant (2) is in a position beyond the standard position, and, when the first situation is given, the controller activates the first and second restraining elements only, especially the tensioning unit for tensioning the seat belt (4) of the second restraining element and the airbag (22) of the first restraining element, whereas, when the second situation is given, a third restraining element integrated in the vehicle seat (6) and/or operatively connected with the vehicle seat (6) can be activated and/or connected by the controller so that the vehicle seat (6) is moved initially via the third restraining element to a position within the range of the standard position.

A seat belt retractor (40) having a belt spool (14), a seat belt (12) that can be wound thereon to a belt spool, and at least a first and a second assembly (1, 2), wherein the first and the second assembly (1, 2) are arranged coaxially to each other and at a first angle (A) to the rotational axis (B) of the belt spool (14) and are connected together by a flex coupling or an angular gear.

A webbing take-up device is provided with a spool that takes up a webbing, a lock base, and a cover plate that covers an outer periphery of the lock base. A tooth portion is formed at the outer periphery of the lock base. The lock base rotates the spool when a rack contacts the tooth portion. The webbing take-up device is further provided with a guide provided at the cover plate. The guide supports the lock base to be rotatable. Thus, contacting together of the ratchet teeth and the lock base is restricted.

The occupant restraining device for a vehicle has a seatbelt, a collision predicting sensor, a braking device that enlarges a gap between a vehicle occupant and a seatback of a vehicle seat, an explosive-type pretensioner and electric motor that retract the seatbelt, and a control section that, in a case in which a front collision of the vehicle is sensed in advance by the collision predicting sensor, enlarges the gap between the vehicle occupant and the seatback by the braking device and starts retracting of the seatbelt by the explosive-type pretensioner and the electric motor, and at least until forward movement of the vehicle occupant starts after occurrence of the front collision, continues to input load to the vehicle occupant from the seatbelt and continues to move the vehicle occupant toward a vehicle rear side.
