A seat is configured to suitably restrain a warping of a connecting portion in a signal transmission path, when the connecting portion is disposed inside a through hole provided in a pad member of the seat. The seat includes: a pressure sensor that detects a seating pressure of a seat occupant; a leading wire of the transmission path that extends from the pressure sensor; a cable of the transmission path that extends from an electronic control unit for a signal output from the pressure sensor; a warp restraining member that restrains a warping of a connecting portion of the leading wire and the cable; and a through hole formed in a pad member of the seat, from one end to another end in the thickness direction of the pad member. The warp restraining member is inserted into the through hole to thereby pass the transmission path through the through hole.

A carpet which forms a terminal of a cushion cover is folded back in a direction opposite to a direction in which the carpet extends from the cushion cover to form a folded portion, a wire is enclosed inside the folded portion to stitch the carpet, a locking hole is opened in a position of the folded portion closer to a cushion cover side than the wire, and a locking plate on a cushion frame side is locked to the locking hole.

A trim cover fixing structure used in a vehicle seat 1 comprising a cushion body 16 having elasticity and a trim cover 17 covering the cushion body 16. This structure comprises engagement members 19a, 19b and 19c anchored near the edge of the trim cover 17, and an fixing member 23 provided with an engaging member (periphery 32) that engages with the engagement members 19a, 19b and 19c existing on the trim cover 17 in a state covering the cushion body 16. The fixing member 23 can apply tension to the trim cover 17 covering the cushion body 16 by engaging with the engagement members 19a, 19b and 19c, and in this state with tension applied, the trim cover 17 is anchored to the surface of the cushion body 16. This trim cover fixing structure has a simple structure and low cost and can apply desirable tension to the trim cover, and furthermore is easily applied to a vehicle seat having a split rear seat structure.

An airbag module-equipped seat in which the periphery of an attachment portion of a guide member that guides a deployment direction of an airbag has a compact size and the guide member can be attached easily while maintaining satisfactory deployment performance of the airbag. This seat includes an airbag module attached to a side frame, a guide member that guides a deployment direction of the airbag module, and an attachment member for attaching the guide member to the side frame. The side frame has an attachment hole for the attachment member at a position different from a shaft portion for attaching the airbag module. The attachment member has a holding space in which an end of the guide member is held in a detachable manner, and is inserted into the attachment hole in a state in which the end of the guide member is held in the holding space.

A vehicle seat includes a seat frame supporting a base cushion and an extendable cushion that moves relative to the base cushion. Textile material encloses the cushion assembly and includes a bridging segment that spans a space between the base cushion and the extendable cushion. A tensioner includes a roller that receives the segment of textile material wrapped around the roller. The roller rotates on a shaft relative to the seat frame about an axis of rotation. A return spring is connected to the roller and the shaft to exert a tensioning force on the segment of textile material. The return spring biases the segment of textile material to be rolled around the roller when retracting. The return spring resists extending and holds the segment of textile material in tension when the segment of textile material is extended.

A retaining element for a cover retaining assembly of a vehicle seat may have a fastening region for a cover fastening element and at least one anchoring region for foaming into a cushion element. The retaining element is in the form of a one-part, bent wire or a one-part, filiform plastic structure. The bent wire or the filiform plastic structure is shaped in the anchoring region in such a way that at least one anchoring opening is defined which has at least one concavity directed towards the fastening region. A set of multiple retaining elements formed as identical parts may also be used in association with a cover retaining assembly and a vehicle seat.

A seat for use with a vehicle is provided. The seat includes a base, a cushioning material coupled to the base, an outer cover positioned over the base and the cushioning material, the outer cover including at least one accessory portion comprising at least one strap coupled to a seam of the outer cover and a securement component coupling the at least one strap to the outer cover.

A seat cushion of a seat, which can avoid creation of wrinkle or crease in an area of a trim cover element corresponding to a lateral side of the seat cushion, irrespective of a downward load applied to the seat cushion, thereby making it possible to maintain an outer appearance of the seat cushion in a good quality condition. In a surface of a recessed region of a padding forming a part of the seat cushion, defined flexible portions are formed to be flexed in an inward direction by a downward load applied thereto. Non-bonding areas are defined between the trim cover element and the flexible portions.

A structure of wadded-up seat trim cover, having a plurality of trim cover pieces sewn together at one end, each composed of a wadding member and a skin member, includes a bonded portion formed by bonding the skin member to the wadding member made shorter than the skin member, at a position remote, by a prescribed distance, from the end of the wadding member overlapping the skin member; a first sewn portion formed by bending that portion of the skin member, not overlapping the wadding member, along the end of the wadding member and then by sewing the portions of the adjacent skin members together; and second sewn portions formed by bending each end of the adjacent skin member to the back of the trim cover piece at the first sewn portion and then by sewing the adjacent skin members together at overlapping portions.
