Abstract: A lift-up buckle device including a buckle; a lift-up device that includes a coupling portion coupled to the buckle and that moves the buckle from a stowed position to a raised position; a first cover fixed to the lift-up device to cover the coupling portion; and a second cover through which the first cover is inserted, that moves together with the buckle toward a seat upper side. When the buckle is positioned in the raised position, a seat lower side end of the second cover is positioned further toward the lift-up device side than a seat upper side end of the first cover, and an end of the second cover on a seat width direction outside and seat lower side is positioned further toward the lift-up device side than an end of the second cover on a seat width direction inside and seat lower side.

Abstract: A reduction in the durability of a coupling member coupled to a buckle is suppressed. A lift-up buckle device includes a buckle that engages with a tongue inserted through webbing worn by an occupant, and wires that each have a portion fixed to the buckle and that are displaced to move the buckle. The lift-up buckle device also includes a wire guide that includes a guide groove that guides the wires, and a soft lower cover that engages with the wire guide and covers the wires. A dimension of an end portion on the buckle side of the guide groove is set so as to increase on progression toward the buckle side.

Abstract: 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.

Abstract: A buckle device includes: a buckle body to which a tongue portion mounted on a three-point seat belt is to be connected; a connecting member that is flexible and that has a first longitudinal end portion connected to the buckle body; and a force limiter mechanism including a take-up shaft around which a second longitudinal end portion of the connecting member is wound, the take-up shaft being supported below the buckle body in a vertical direction of a vehicle so as to be rotatable relative to a vehicle seat or a vehicle body, and an energy absorbing member that is deformed by rotation of the take-up shaft.

Abstract: At a lift-up buckle device, due to a motor being driven and an output shaft of the motor being rotated, a drive screw is rotated. Further, a supporting tube rotatably supports a rear end portion of the drive screw. Here, the output shaft rotatably supports a front end portion of the drive screw. Therefore, offset between a rotation central axis of the output shaft and a rotation central axis of the drive screw can be suppressed.

Abstract: 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.

Abstract: In a buckle device, wire ropes and a coiled cord run through the inside of a tubular buckle guide. Here, a partition wall is provided inside the buckle guide, and the inside of the buckle guide is partitioned by the partition wall into a wire rope side and a coiled cord side. Due to this, the coiled cord can be prevented from contacting the wire ropes inside the buckle guide.

Abstract: In a buckle device, displacement of a buckle cover in a width direction with respect to a buckle guide is restricted by restricting grooves of the buckle cover and restricting ribs of the buckle guide that enter the restricting grooves. This enables a space to be secured between a wall portion on one side in a width direction of the buckle cover and a wall portion on one side in a width direction of the buckle guide.

Abstract: 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.
