In a seat belt device, when a buckle cover is moved obliquely upward in a vehicle forward direction relative to a buckle guide and the buckle cover reaches a moving endpoint at a vehicle upper side relative to the buckle guide, cover-side engagement portions of the buckle cover become sandwiched between vehicle lower side surfaces of guide-side engagement portions of the buckle guide, and the outside surfaces of guide long-side wall portions of the buckle guide. Due to this, not only movement of the cover-side engagement portions of the buckle cover in the vehicle upward direction but also movement of the cover-side engagement portions outwards in the thickness directions of the cross-sectional shapes of the buckle cover and the buckle guide are restrained by the guide-side engagement portions.

It is provided a chain link for a link chain which is flexible per se and in which chain links connected to each other are movable in relation to each other and can be locked to each other such that the link chain which is flexible per se can be stiffened by locking the chain links to each other. The chain link has at least a first connection segment for the connection to a first chain link and a further second connection segment for the connection to a second chain link. The chain link has a carrier having the first connection segment and has an adjustment part having the second connection segment, said adjustment part being supported in an adjustable manner relative to the carrier.

In a lift-up buckle device, a slider and a shoe move forward and a buckle is moved to a stowed position. The shoe impacts against a protruding portion at a lower portion of a damper and interferes with a housing via the lower portion of the damper. Thus, the forward movement of the slider and shoe is stopped, while the damper absorbs an impact against the slider and shoe. Therefore, an amount of the impact against the slider and shoe that is absorbed by the damper may be increased by the protruding portion, and the damper may absorb the impact against the slider and shoe effectively.

In a lift-up buckle device, a slider and a shoe are provided at a seatbelt device. The slider and the shoe are moved by a drive screw that is driven by an output shaft of a motor. Here, a buffering body is provided at the output shaft, and concave portions are formed at corner portions of an inserted-into portion. Therefore, projecting portions which project-out into the inserted-into portion being formed at the corner portions of the inserted-into portion when the buffering body is molded can be suppressed, and corner portions of the output shaft interfering with the projecting portions can be suppressed. Accordingly, because rattling of the output shaft within the inserted-into portion can be suppressed, operating noise can be reduced.

A buckle device including: a buckle that is configured to engage with a tongue of a seatbelt device, a cover member that includes a first member and a second member for assembly together, and at which the buckle is provided; an elongated member that is anchored to the first member at a length direction leading end portion of the elongated member, and a retention section that is provided at the first member, and that is configured to engage a portion of the elongated member that is further toward a length direction base end side of the elongated member than the length direction leading end portion.

A lift-up buckle device has a buckle with which is engaged a tongue through which a webbing, which is applied to a vehicle occupant, is inserted; wires that are made of metal, and whose longitudinal direction one end portions are fixed to the buckle, and that move together with the buckle; a driving portion that is connected to longitudinal direction other end portions of the wires, and that move the wires in a longitudinal direction; a wire guide that is made of metal and holds the wires in a curved state; a guide groove that is formed in the wire guide and in which the wires are inserted; and a resin member that is provided at an interior of the guide groove and abuts the wires.

A vehicle pre-crash seat belt device includes: a buckle moving mechanism that moves a buckle, with which a tongue that has a webbing inserted therein engages, between a normal position and a raised position that is further toward a seat upper side than the normal position; a retractor that includes: a spool and a lock mechanism that locks rotation of the spool in the pull-out direction, and that releases the locked state by causing rotation of the spool in the take-up direction; and a controller that, due to a signal from a collision prediction sensor that predicts a collision of a vehicle, causes rotation of the spool in the take-up direction and increases tension acting on the webbing, and actuates the buckle moving mechanism to move the buckle from the normal position toward the raised position in a case in which the vehicle collision has been avoided.

In a buckle device, cord portions that are pulled out from a distal end portion in a longitudinal direction of a helical portion of a curl cord are electrically and mechanically connected to a terminal of a buckle switch of a buckle. The distal end portion in the longitudinal direction of the helical portion of the curl cord is held by a holding bracket that is provided at a first cover component of a buckle cover. Consequently, even when the buckle cover is moved, excellent connections can still be maintained between the cord portions of the curl cord and the terminal of the buckle switch of the buckle.
