A three-point seatbelt device includes: a webbing configured to function as a shoulder belt and a lap belt; a shoulder-side reeler that includes a pre-tensioner mechanism and a shoulder-side force limiter mechanism, and is configured to reel up an end portion of the webbing on a shoulder belt side so as to allow the webbing to be pulled out; a tongue mounted on the webbing; and an inner belt including a buckle to which the tongue is coupled, the inner belt including, of a pre-tensioner mechanism and a buckle-side force limiter mechanism, only the buckle-side force limiter mechanism. An initial load of the buckle-side force limiter mechanism is set to be larger than an initial load of the shoulder-side force limiter mechanism.

A seatbelt anchor includes an attachment portion. The seatbelt anchor includes a seatbelt support portion spaced from the attachment portion to define a slot therebetween. The seatbelt anchor includes a pair of connecting portions spaced from each other with the slot disposed therebetween and connecting the attachment portion to the seatbelt support portion and including a lattice structure that is plastically deformable relative to the attachment portion and the seatbelt support portion.

A webbing take-up device in which, when a pretensioner mechanism is activated and turning of a pinion relative to a spool is allowed, a lock pawl is turned by the pinion and a trigger wire is sheared by the lock pawl. Thereafter, the pinion turns more relative to the lock pawl and shears a lock pin of the lock pawl. Hence, the lock pawl turns and activates an activation mechanism. Therefore, the activation mechanism may be activated without a torsion shaft of a force limiter mechanism allowing turning of a lock base in the take-up direction relative to the spool.

A webbing take-up device includes a spool, a lock base that restricts pull-out direction rotation of the spool in a vehicle emergency, and a linear energy absorbing wire that deforms so as to permit pull-out direction rotation of the spool at or above a force limiter load when the lock base has restricted pull-out direction rotation of the spool. The webbing take-up device further includes a housing with which the energy absorbing wire engages along a radial direction inside face of the housing, and a winder section provided at a radial direction inside of the housing. The winder section is capable of rotating together as a unit with the spool, and takes up the energy absorbing wire by being rotated. Moreover, a wire guide and a lever are provided between the winder section and the housing. The wire guide and the lever pinch and deform the energy absorbing wire.

A safety belt retractor, a vehicle safety belt with the safety belt retractor and a vehicle with the vehicle safety belt are provided. The safety belt retractor is provided, on an end segment thereof, with a pre-tensioning, force-limiting and decoupling device that comprises a safety belt reel (1), a driving element (2), a sleeve (3) and an energy absorbing disc (4). The safety belt reel (1) is provided with a first recess (10) and a second recess. A first helical surface (9) is arranged in the first recess (10), and the driving element (2) is provided with a first projection (21) having a second helical surface acting together with the first helical surface (9). The sleeve (3) is provided with a second projection (31) mounted in the second recess. Under a predetermined load, the second projection (31) is cut off, such that the energy absorbing disc (4) is plastically deformed due to squeezing. The safety belt retractor achieves on the same end segment, the pre-tensioning, force-limiting and decoupling functions as well as a compact structure.

A webbing take-up device includes: a spool that takes up webbing worn by an occupant and is rotated in a pull-out direction due to the webbing being pulled out; a base lock that is provided capable of rotating integrally with the spool and is restricted from rotating in the pull-out direction of the spool in vehicle emergency; a pawl that is rotated together with the spool and that, by being displaced to an engaged position, engages with a winding ring and transmits rotation force of the spool to the winding ring; and a trigger ring that is provided capable of being displaced in a rotation circumferential direction of the spool with respect to the spool and includes a pawl-abut portion, abutting the pawl and displacing the pawl to the engaged position when the spool is rotated in the pull-out direction with respect to the lock section.

A webbing take-up device includes a spool taking up webbing worn by an occupant, that is rotated in a pull-out direction by the webbing being pulled-out; a base lock that is provided capable of rotating integrally with the spool and restricts rotation of the spool in the pull-out direction in vehicle-emergency; a pawl that is rotated together with the spool and, by being displaced, engages with a winding ring and transmits rotation force of the spool to the winding ring, and a trigger ring including a restricting portion that is disposed in a restricting position at which displacement of the pawl is restricted in a state prior to the spool being rotated with respect to the base lock, and is disposed in a permitting position at which displacement of the pawl is permitted when the spool has been rotated in the pull-out direction with respect to the base lock.

In a buckle device, a wire harness is connected to a buckle body, and the wire harness is mounted to a mounting plate of a boot. Therefore, in a case in which, at the time of light collision of a vehicle, tension is applied to a belt to extend the belt, and the buckle body is extended upward, the mounting plate is elastically bent, and the upward movement of the wire harness is allowed. Accordingly, it is possible to suppress disconnection of the wire harness.

A vehicle seatbelt assembly includes a first member, a second member, a buckle mechanism, and a clutch mechanism. The first member is configured to attach to one of a vehicle floor structure and a seat structure. The second member is supported on the first member. The second member is configured for limited sliding movement relative to the first member. The buckle mechanism is attached to the second member for movement therewith. The buckle mechanism has a latch device configured to releaseably retain a seatbelt latch tongue member. The clutch mechanism is disposed between the first member and the second member and is operable to switch between a dis-engaged state and an engaged state. In the dis-engaged state, the clutch mechanism allows movement of the second member relative to the first member. In the engaged state, the clutch mechanism prevents movement of the second member relative to the first member.

An inertia reel mount for a seat includes a slide, a carriage arranged to support a seatbelt inertia reel, and a damper. The carriage is movable between first and second positions relative to the slide. The damper is fixed to the slide, is arranged between the carriage and the slide to oppose movement of the carriage, and is arranged to absorb kinetic energy from the carriage from sudden acceleration of a seat occupant secured in the seat by the seatbelt as the carriage moves from the first position to the second position.
