A motor vehicle, seat and multi-point restraint system combination may include one or a combination of means for selectively preventing forward pivoting of the seat, one or more web attenuators for dampen forces applied thereby by one or more respective shoulder webs of the multi-point restraint system, at least one sleeve received on at least one shoulder web and a corresponding sleeve adjuster for adjusting a position of the sleeve along the respective shoulder web, web retractors operatively coupled to each of a pair of lap webs and to each of a pair of thigh webs of the multi-point restraint system, and at least one web retractor operatively coupled to the shoulder webs of the multi-point restraint system.

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 pretensioning lapbelt apparatus where the pretensioning of the lapbelt is performed by the rapid inflation of an airbag that is integral to the lapbelt itself. The design of the airbag, including the attachment locations of the ends of the webbing are chosen such that, upon inflation of the airbag, the free end of the webbing—the end of the webbing that is passed through the cinching latch—is pulled taught, thereby reducing the effective length of the lapbelt. The anchor is designed to be a cinching anchor such that once the airbag deploys and pulls the webbing through the anchor (thereby pretensioning the lapbelt) a sliding pin in the anchor “cinches” the webbing, effectively locking the webbing in the pretensioned state.

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 locking apparatus of a buckle of a seat belt for vehicles includes a sector gear bracket configured to be integrally coupled to a rear pipe which is coupled to a seat cushion frame, wherein the sector gear bracket has: an arc-shaped locking hole; and a sector gear arranged along the locking hole as an internal gear; a pole bracket located at one side of the sector gear bracket, wherein the pole bracket has a shaft part which is configured to pass through the locking hole and the seat cushion frame and then be integrally coupled to a lower end of the buckle; and a lock gear arranged on the pole bracket as an external gear.

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).

An assembly includes a rod, a tube slidably supported by the rod, a seatbelt buckle supported by the tube, and a lock. The tube and the rod are releasably engageable to each other by the lock.
