An occupant crash protection includes: a seatbelt that restrains a front-seat occupant sitting in a front seat; a retractor that is installed inside a seatback of the front seat and reels in one end side of the seatbelt, inserted inside the seatback, so as to allow the seatbelt to be pulled out; and a rear-seat airbag module that is installed inside the seatback, on a seat rear side relative to the seatbelt, and inflates and deploys an airbag toward the seat rear side of the seatback while inflating a part of the airbag toward a seat front side so as to press the seatbelt toward the seat front side.

A seat belt pretensioner for a motor vehicle includes a cam that rotates, a cable with a first end and a second end, a section of the cable positioned on an outer portion of the cam. Upon deployment the cam rotates and guides the first end from a first location to a second location.

An anchor pretensioner module for a seat belt includes: an anchor which is disposed at a side of a seat cushion, and to which a tongue of the seat belt is fastened, a base which is provided at a lower side of the anchor, the base having a first operating part, which generates an explosive pressure, provided at a rear of the base, and a second operating part, which generates the explosive pressure, provided at a front of the base, a first wire which is connected to the base and the anchor, and allows the anchor to be moved downward when the first operating part is operated, and a second wire which is provided on the base, and moves the first wire while being inserted into the base when the second operating part is operated to allow the anchor to be moved forward while moving downward, so that a relative location of the anchor is moved when a collision occurs to restrain a passenger's body.

A seat belt pretensioner of a vehicle include: a displacement generator to generate a linear displacement in a seat frame; and a webbing guide that receives the linear displacement generated by the displacement generator and pulls a webbing. In particular, the webbing extends from a retractor fixed to the seat frame to the outside of the seat.

A force-limiting device, especially for a seat belt system (10) in a vehicle, has a force transducer (20) interacting with webbing (14) for which a normal webbing path is provided. The force transducer (20) includes a webbing track (30) that in a non-force-limiting position extends in parallel to the normal webbing path and in a force-limiting position extends inclined relative to the normal webbing path so that the force transducer (20) in the force-limiting position sets a predetermined extension force (F) required to move the webbing (14) vis-à-vis the force transducer (20) in a direction of belt extension (R).

A seat belt system for restraining an occupant of a vehicle. The system includes a webbing and a pretensioner. A cable connects the webbing to the pretensioner. The pretensioner includes a housing, a gas generator, and an outer cylinder connected to the housing. A gas generator provides gases into a pressure chamber in the outer cylinder to drive a piston, an inner cylinder and the cable in a pretensioning direction. A sealing ring is located between the outer cylinder and inner cylinder. The sealing ring is configured to provide a seal to prevent the gases provided by the gas generator from passing. A deflector shield is located between the outer cylinder and the inner cylinder and closer to the pressure chamber than the sealing ring, wherein the deflector shield is configured to deflect the gases away from the sealing ring.

An assembly includes a housing. The assembly includes a spool rotatable relative to the housing. The assembly includes a cable fixed to the spool. The assembly includes a passenger restraint fixed to the cable. The assembly includes a pyrotechnic device fixed relative to the housing and designed to rotate the spool relative to the housing. The assembly includes a ratchet-and-pawl mechanism between the housing and the spool.
