Abstract: A seat for a vehicle includes: a recliner configured to allow a back frame to pivot about a prescribed pivot axis with respect to a cushion frame. The seat frame is provided with a through hole arranged around the pivot axis. The recliner has a protruding portion fitted into the through hole. The seat further includes a joint portion formed by joining the seat frame and the recliner using laser welding. The joint portion has an outer circumferential portion, an inner circumferential portion and a circumferential end portion. The outer circumferential portion extends along an edge on an outer circumferential side of the through hole. The inner circumferential portion extends along an edge on an inner circumferential side of the through hole. The circumferential end portion extends along an edge on an end side of the through hole and connects the outer circumferential portion and the inner circumferential portion.

Abstract: A grommet includes a body cylinder, an attachment cylinder, and a resilient retention portion. The body cylinder is configured such that a line shaped member is insertable therethrough. The attachment cylinder is provided at one end portion in an axis direction of the body cylinder and is configured to be attached to an opening formed at an attachment target. The resilient retention portion is provided between the body cylinder and the attachment cylinder, and is configured to resiliently deform to abut and retain the line shaped member.

Abstract: In a clip, first and second attachment portions are coupled by a coupling portion in an open state in which a seatback spring is able to pass between the first and second attachment portions in the radial direction of the seatback spring. The first and second attachment portions swing in mutually engaging directions. The first attachment portion is formed with a first placement portion, and the second attachment portion is formed with a second placement portion. The seatback spring can accordingly be placed between the coupling portion and either the first placement portion or the second placement portion. In this placed state, the seatback spring is retained in the clip by engaging an engagement claw of the first attachment portion with a peripheral edge portion of an engagement hole of the second attachment portion, enabling fixing to an attachment portion of a lower frame.

Abstract: A vehicle seat includes: a seat cushion; a base provided on a vehicle body; a seat lifter configured to adjust a height of the seat cushion by a rotational motion of a link connecting the seat cushion to the base; and a fixture of a seat belt, the fixture being attached to the link.

Abstract: A conveyance seat includes a seatback frame disposed in a seatback and supporting an end of a wire member for supporting an occupant in a manner such that the wire member is movable. The seatback frame includes a supporting plane part that the end of the wire member is disposed therein, the supporting plane part being provided along a direction perpendicular to a longitudinal direction of the wire member. A support portion that supports the wire member in a manner such that the wire member is movable is formed in the supporting plane part.

Abstract: There is disclosed a clip attaching structure of a vehicle seat. The seat frame includes an attaching hole and an expanded hole which expands a hole thereof from the attaching hole in a radial direction. The clip includes a fitting portion inserted into the attaching hole to fit in an inner periphery of the attaching hole, and an extending portion which extends a shape thereof from the fitting portion in the radial direction to be inserted into the expanded hole. A tip of the extending portion extends beyond the fitting portion in an inserting direction. On a tip surface of the extending portion in the inserting direction, a guide surface is formed to abut on a peripheral edge portion of the expanded hole when an inserting position of the fitting portion shifts from the attaching hole in the radial direction, thereby guiding the fitting portion toward the attaching hole.

Abstract: When an attachment circular-cylinder section coupled to one axial line direction end portion of a mainbody circular-cylinder section of a grommet is inserted into an opening portion in an upper frame, engagement claws formed at an outer periphery of the attachment circular-cylinder section engage with a peripheral edge portion of the opening portion by elastically deforming, enabling the grommet to be attached to the upper frame. When a seatback spring is passed through the grommet, a retaining section formed at an inner peripheral portion of a boundary between the mainbody circular-cylinder section and the attachment circular-cylinder section retains the seatback spring.
