Abstract: To provide a flat reclining posture that becomes approximately parallel to a floor surface of a vehicle. A vehicle seat includes a seat cushion, a seat back, risers, a reclining mechanism, a first link member, a second link member, and tracks. The seat cushion includes a cushion frame. The seat back includes a back frame. The reclining mechanism is disposed at an upper portion at a rear end of the riser. The reclining mechanism is coupled to a lower end portion of the back frame. The first link member is rotatably disposed between a rear end portion of the cushion frame and the reclining mechanism. The second link member is rotatably disposed between upper portions at front ends of the risers and front end portions of the cushion frame. The tracks are disposed at lower portions of the risers.

Abstract: To provide a technique that allows comparatively easy mounting of a cover (finisher) that covers a bottom surface of a headrest body. A headrest includes a headrest body, a headrest pillar, and a finisher. The headrest pillar projects from a bottom surface of the headrest body. The finisher has an opening portion into which the headrest pillar is inserted. The headrest pillar extends to an inside of the headrest body. The finisher is fixed to the headrest pillar at the inside of the headrest body. The finisher covers the bottom surface of the headrest body.

Abstract: An integrated child booster seat, to allow more securely switching of a usual seat and a child seat with a relatively simple configuration, in which a seat cushion is configured by a cushion part in which a seat for a general passenger is formed on one side and a child seat is formed on the reverse side, a coupling pipe which coaxially supports the front and the back of the cushion part and which is swingably held with outside of lateral sides of the cushion part in the center of turning, supporting parts that bind and support the cushion part, and binding release parts that release binding by the supporting parts of the cushion part.

Abstract: A headrest includes: (a) a headrest frame, (b) a speaker unit supported by the headrest frame and having a speaker box, a speaker attached to the speaker box, and a megaphone-shaped tube attached to the speaker box, (c) a cushion material, (d) a skin material having an opening, sewed into a pouch shape, and covering the headrest frame, the speaker unit, and the cushion material, and (e) a ring-shaped member securing the entire opening-side end portion of the skin material sandwiched between the ring-shaped member and the megaphone-shaped tube.

Abstract: A vehicle seat is provided with: a seat cushion frame; a seat back frame; a seat cushion main part that is fitted to the seat cushion frame; a seat cushion side part that is arranged on a side portion of the seat cushion main part and that is fitted to the seat cushion frame; a seat back main part that is fitted to the seat back frame; and a seat back side part that is arranged on a side portion of the seat back main part and that is fitted to the seat back frame. Here, each of the seat cushion main part and the seat back main part is composed of a plurality of segments, and each segment has a foam part, and the foam part is separated from the foam part of the other segment.

Abstract: A vehicle seat is equipped with a seatback having a mounting portion, a headrest having a headrest frame and an electric component, a first connector, and a second connector. The first connector has an engaging portion engaged with a hole of the headrest frame, a protrusion engaging the second connector, and a first connector terminal electrically connected to a lead wire of the electric component. The second connector has a first engaging piece engaged with a hole of the guide bracket from the outside of the guide bracket, a second engaging piece engaged with the protrusion of the first connector from the outside of the first connector, and a second connector terminal electrically connected to a lead wire wired in the seatback and the first connector terminal. The engagement between the hole of the mounting portion and the first engaging piece of the second connector can be released irreversibly.

Abstract: A vehicle seat is provided with a seat sliding mechanism (a) including a lower rail and an upper rail fitted and moved in the lower rail, a seat structure (b) equipped with a seat cushion frame including a seat side member and a seat back frame, an upper riser (c) fixed to the upper rail and supporting the seat structure, and a seat inclining mechanism (d) that enables inclining of the seat structure for the upper riser. When the seat structure is inclined by the seat inclining mechanism, an angle between the seat cushion frame and the seat back frame is maintained and the rear of the seat cushion frame is located on the upside of the rear of the seat cushion frame in a state before the seat structure is inclined by the seat inclining mechanism.
