In the buckle device, when or after torsional deformation of the torsion shaft has started and allowance of the drawing-out of the belt has started, the breaking portion of the shear plate is started to be deformed by the coupling hole side surface of the spool, whereby the breaking portion allows the rotation of the spool and allows the drawing-out of the belt. Therefore, the allowable drawing-out load of the belt can be made the sum of the load for torsionally deforming the torsion shaft and the load for deforming the breaking portion, and can be increased.

A seat belt anchor is provided, wherein the seat belt anchor includes: a main body including a locking slot having an opening and an inner surface; and a locking member movably connected to the main body and movable between a lock position and a release position; wherein when the locking member is in the lock position, the locking member projects toward the locking slot to define a distance between the inner surface of the locking slot and the locking member which is larger than a diametric dimension of a shaft body of the fastener so that it allows the shaft body of the fastener to axially pass through the locking slot; wherein when the locking member is in the release position, it allows a ring body of the fastener to directly pass through the opening to be in the locking slot.

A vehicle includes a vehicle seat and a plate fixed relative to the vehicle seat. A seatbelt buckle is rotatably supported by the vehicle seat. The seatbelt buckle is rotatable relative to the plate from a first position to a second position. A slot is in one of the plate and the seatbelt buckle and a pin is supported by the other of the plate and the seatbelt buckle. The pin is moveable relative to the other of the plate and the seatbelt buckle from a retracted position to an extended position. The pin is spaced from the slot and in the retracted position when the seatbelt buckle is in the first position. The pin is in the extended position and extends into the slot when the seatbelt buckle is in the second position. A pyrotechnic device is operatively coupled to the seatbelt buckle to rotate the seatbelt buckle.

A crash-tested single point restraining device comprising a housing having a tensioning and retracting mechanism which is mechanically coupled to a reel assembly secured within the housing, a proximal end having a standard seat belt insert member and/or an anchoring point connecting element, an extendable and retractable seat belt webbing anchored within the housing having a high strength swiveling carabiner at a distal end, a stitched area formed near said distal end of the retractable seat belt webbing, and a retraction limiting component integrated on the seat belt webbing between the housing and the stitching to prevent damage to the stitching. In one embodiment, the housing is affixed permanently to an interior location of a vehicle. In another embodiment, the high-strength swiveling carabiner is composed of 7075 aluminum alloy.

A seatbelt buckle includes a frame operable to receive a seatbelt latch plate therein. A retainer is carried by the frame and movable between a latched position and an unlatched position. A resilient member is positioned between the frame and the retainer to urge the retainer toward the unlatched position. An actuator is positioned to lock the retainer in the latched position when activated.

The present disclosure provides a buckle, including a male buckle having an engaged portion; a female buckle including a housing, a cover, and a locking member, the housing and the cover enclosing an accommodation space, the locking member being movably disposed in the accommodation space, the locking member having an engaging portion, the engaging portion having a locked position in which it is locked with the engaged portion and an unlocked position in which it is unlocked from the engaged portion; and an operation member, which is movably disposed on the female buckle to selectively actuate the engaging portion to be unlocked from the engaged portion. The cover or the locking member is provided with an elastic member which applies a force to the engaging portion in a direction towards the locked position. The present disclosure provides a buckle with simple structure, light weight, and low assembly cost.

A vehicle seat belt fastening device is provided for a seat belt equipped with a strap and a closing mechanism. The seat belt is simultaneously linked to the vehicle floor and able to be linked in a sliding manner to the strap. Thus, the seat belt is suitable for holding the strap in relation to the closing mechanism, and therefore in relation to the vehicle floor. A tool that is able to be attached and removed in relation to the closing mechanism. The tool is also able to be manually manipulated, and to be manually attached and/or manually removed in the attachment and/or removal position thereof from the closing mechanism. The tool is equipped with means for cutting the strap and/or with means for breaking the windows of the vehicle.

A locking tongue for a seat belt of a vehicle according to one embodiment includes: a tongue body including a main wall and a pair of side walls; a clamp member slidable in a direction toward the main wall; a rotating member rotatably supported by the side walls; and an urging member that urges the clamp member in a direction away from the main wall. In a normal state, a gap larger than a thickness of a webbing that is the seat belt is formed between the clamp member and the main wall. In an emergency of the vehicle, tension of a lap belt becomes greater than tension of a shoulder belt, causing the rotating member to rotate in a direction from the shoulder belt toward the lap belt against urging force of the urging member, such that the webbing is clamped between the clamp member and the main wall.

A lockbar in a tongue of a seat belt system in a vehicle, wherein the crash locking tongue includes the lockbar, a base plate, and a cover material overmolded onto the base plate. The base plate is configured to be reversibly coupled to a buckle in the seat belt system and to have a slot through which a belt webbing extends in order to restrain the movement of a passenger in the vehicle. The lockbar includes one or more fins located on a bottom surface near a front edge, a pair of guide wings located on a back edge adjacent to opposite sides, a clamping surface that is in contact with the belt webbing, and an elastomeric spring. The lockbar undergoes a vertical translation upon a vehicle accident that causes a clamping surface to apply an inward pressure on the belt webbing, thereby, reducing movement of the belt webbing.
