A surface fastener formed of a synthetic resin and in which a base with a 0.1 to 0.9 mm thickness and engagement element groups including engagement elements with a 0.2 to 0.8 mm protrusion height are integrally molded, and engagement element rows are composed of the plural engagement elements arranged in a row direction and each protruding independently. A cushioning member is covered with a covering member via the surface fastener. A resistance value of the surface fastener by itself as measured by a handle-o-meter method conforming to the JIS L 1096 E method is 80 to 150 g, whereas a load-deflection characteristic when a pressure is applied to an overlapping portion of the stacked surface fastener and cushioning member by a pressure plate with a 30 mm diameter approximates a similarly measured load-deflection characteristic of the cushioning member by itself.

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.

An apparatus for stitching an interior component is disclosed herein. The component having an outer skin layer and the apparatus is a single needle chain stitch machine with a rotary looper and wherein a needle of the apparatus descends through the interior component and a hook of the rotary looper engages a thread loop formed during retraction of the needle after it has descended through the interior component; and wherein the apparatus further includes a mechanism for moving the interior component relative to the needle and looper to establish a stitch length.

A vehicle seat including: a seat cover including: a general cover part; and a sheet-shaped member configured by one sheet and folded inward, and an internal structure covered with the seat cover, and the sheet-shaped member has: a drawing cover part locked to the internal structure; and a concealing cover part covering the drawing cover part from outside of the seat, the sheet-shaped member has: a connection end part; and a pair of free end parts extending from the connection end part, and the sheet-shaped member is connected to an edge of the general cover part at a connection part on the connection end part, and the drawing cover part is formed at one of the pair of free end parts disposed inside the seat and the concealing cover part is formed at the other one of the pair of free end parts disposed outside the seat.

In order to solve the issue, during recessed-shape molding for vehicle seats, of requiring a suspension step, more work, members for suspension, and increased cost in a method using suspension, a recessed-shape molding method is provided for vehicle seats having a seat frame, a seat pad covering the seat frame, and a trim cover covering the seat pad. The seat pad has a seat pad groove. An adhesive sheet is sewn on to the rear surface of the trim cover by using outer stitching, the trim cover is put on to the seat pad, then a die is pressed on to the outer stitching from the trim cover surface, the trim cover is adhered to the seat pad groove, and a recessed shape is formed. As a result, a vehicle seat having simplified molding steps and effectively reducing costs can be provided, as well as a vehicle seat molding method used for same.

A seat covering for a seat includes a first covering having a first perforation configuration and a second covering having a second perforation configuration. The second perforation configuration terminates to define a region without perforations adjacent to an edge of the second covering. The first covering and the second covering are joined together at a seam, and a line of stitching is provided along the seam in the region without perforations. One embodiment of the seat covering includes the first covering having a narrow width at the front side of the seat bottom. The first covering widens to a greater width at the rear portion of the seat bottom.

A vehicle seat is provided with a seat cushion and a seat back. The seat back is provided with a resin frame at least a part of the rear surface side of which is exposed; a pad material disposed on the resin frame; a trim cover for covering the pad material; and a resin hook mounted to an end of the trim cover. The resin frame has a turned-back end formed by turning back outward in a U shape an end of the resin frame. The resin hook is engaged with the turned-back end. The resin hook has a protrusion at the portion thereof which is located within the turned-back end.

A vehicle seat is provided having first and second trim panels having an outer appearance surface. An illumination trim portion separates the first and second trim panels. The illumination portion has a pocket formed of translucent material and has first and second lateral flaps disposed on opposite sides of a central tunnel. A first seam secures the illumination portion to the first trim panel and to the first lateral flap. A second seam secures the illumination portion to the second trim panel and to the second lateral flap. A light conducting strip is inserted in the central tunnel of the pocket. A light source is in communication with the light conducting strip. Light from the light source is visible through the translucent material of the central tunnel.

A seat back board includes: a flexible plate member which is made of a resin material and has the Shore hardness higher than 50, the plate member including: a back-surface covering part which covers a back surface of a seat back; and a bottom-surface covering part which covers a bottom surface of a seat cushion; a sewing part, which is sewn with a cover member covering a front surface and side surfaces of the seat back or is sewn with a coupling member to be coupled with the cover member in a detachable manner, being provided in an edge portion of the back-surface covering part; and a locking part, to be locked in the seat cushion, being provided in the bottom-surface covering part.
