A belt reel (14) for a belt retractor (10) has a rotational axis (R) and a reel body (16) that is provided as a reel for a webbing (24) and has a first axial circumferential circle (34). The reel body (16) further includes a radial constriction (32) having a second axial circumferential circle (36), wherein the constriction (32) is arranged centrally on the reel body (16) in the axial direction (A) and wherein the circumference of the second axial circumferential circle (36) amounts to a maximum of 95% of the circumference of the first axial circumferential circle (34). Moreover, a belt retractor (10) comprising such belt reel (14) is described.

A vehicular seat belt device includes a first pretensioner provided in a retractor and configured to apply tensile force to a shoulder belt portion of a webbing, a second pretensioner provided in a belt anchor part and configured to apply tensile force to a lap belt portion of the webbing, a third pretensioner provided in a side portion of the vehicle seat opposite to the belt anchor part and configured to apply tensile force to the lap belt portion via a buckle, and a controller. The controller is configured to activate the first pretensioner at a time of predicting vehicle collision, and activate the second pretensioner and the third pretensioner after detection of collision.

A pretensioner for a seat belt device in a vehicle includes a cable connected to the seat belt device at a first end of the cable. The pretensioner also includes a base frame containing a pipe. A rod is located within the pipe, and one end of the rod is configured to be subjected to pressure from gas provided by a gas generator. A second end of the cable and a second end of the rod are connected to a swage block. The rod is configured to be driven within the pipe in the pretensioning direction by gas from the gas generator when the gas generator initiates in response to an acceleration of the vehicle greater than a predetermined high acceleration thereby causing the swage block to move and pull the cable to thereby cause a corresponding movement of the seat belt device.

A restraint system for a utility vehicle comprising a first restraint including a first retractor coupled to the utility vehicle at a first retractor anchor point, a first webbing retractable into the first retractor and having a first end and a second end, a first latch moveably engaged with the first webbing, and a first latch receiver configured to receive the first latch, and a second restraint including a second retractor coupled to the utility vehicle at a second retractor anchor point, a second webbing extendable from and retractable into the second retractor and having a first end coupled to the second retractor and a second end, a second latch coupled to the second webbing, and a second latch receiver positioned at a second receiver anchor point and configured to receive the second latch and retain the second end of the second webbing adjacent the second receiver anchor point.

A restraint system for a utility vehicle comprising a first restraint including a first retractor coupled to the utility vehicle at a first retractor anchor point, a first webbing retractable into the first retractor and having a first end and a second end, a first latch moveably engaged with the first webbing, and a first latch receiver configured to receive the first latch, and a second restraint including a second retractor coupled to the utility vehicle at a second retractor anchor point, a second webbing extendable from and retractable into the second retractor and having a first end coupled to the second retractor and a second end, a second latch coupled to the second webbing, and a second latch receiver positioned at a second receiver anchor point and configured to receive the second latch and retain the second end of the second webbing adjacent the second receiver anchor point.

The invention relates to a belt retractor surrounding a belt reel which is rotatably mounted in a frame, and comprising a force-limiting device with at least one plastically deformable first torsion rod, wherein the first torsion rod has a first end rotationally fixed to the belt reel and a second end rotationally fixed to a profiled head which can be blocked via a first blocking device in a fixed manner relative to the vehicle. The belt reel, the first torsion rod and the profiled head are arranged coaxially to one another and in series relative to one another.

A vehicle seat (10) for a motor vehicle, having a backrest (12), a height-adjustable headrest (14) and a seatbelt guide (22) integrated in the vehicle seat (10) for a seatbelt (18), wherein the height-adjustable headrest (14) is coupled to the backrest (12), and wherein the headrest (14) can be mechanically coupled to a seatbelt guide adjusting mechanism (36), which mechanically adjusts the seatbelt guide (22) when adjusting the height of the headrest (14).

A bracket for mounting an anchor pretensioner and a retractor for a vehicle seat is provided. The bracket comprises a first plate facing the anchor pretensioner, a second plate facing the retractor and a hollow spacer extending between the first and second plates, and connected to the first and second plates. The hollow spacer is configured to allow a fastener to pass through to connect the anchor pretensioner and the retractor to a vehicle body.

In a webbing retractor, due to a moving member being moved toward an axial direction distal end side, and first teeth and second teeth of a rotating member piercing the moving member, the rotating member is rotated in a take-up direction. Here, at the moving member, a sectional surface area, in a direction orthogonal to an axis, of a small diameter portion that is at an axial direction distal end side is made to be small as compared with a moving member main body that is at an axial direction proximal end side. Therefore, resistance to movement of the moving member can be reduced.
