Abstract: A mat mounting structure for mounting a mat on a seat back frame in a seat back may have a guide wire attachable to the mat configured to receive a force from a back of an occupant on the seat back. The guide wire may have a straight part extending linearly in a longitudinal direction of the seat back frame on a head side or a root side of the seat back frame. A bushing including a penetration hole in which the straight part is insertable in the longitudinal direction may be included in the structure. An attachment hole part in the seat back frame may also be part of the structure. The bushing may be detachably engageable with and attachable to the attachment hole part.

Abstract: A vehicle seat includes an internal support member for supporting a seat occupant. The internal support member includes a main body in plate or sheet form positioned within a seat cushion frame, a pair of inclined portions extending laterally from a part of either lateral side of the main body with an upward slant, and front and rear mounting portions engaged by front and rear cross members of the seat cushion frame. A pressure sensor is mounted on a part of an upper surface of the internal support member located ahead of the inclined portions. The main body of the internal support member is provided with a pair of openings located on either side of the pressure sensor, and a connecting portion connecting the pressure sensor with a part of the front mounting portion. The pressure sensor and the openings are spaced from the front edge of the main body.

Abstract: A vehicle seat includes: a frame provided in at least one of a seat cushion and a seat back; an internal support member for supporting an occupant, the internal support member including a main body in plate or sheet form positioned within the frame and extending substantially in parallel with the frame, and a pair of inclined portions extending laterally outward from at least a part of either lateral side of the main body with a slant away from the frame; a pad placed on a front side of the frame and the internal support member; a skin member covering the pad; and a clip securing another member to one of the inclined portions. The one inclined portion is formed with a tubular portion projecting from a back side thereof orthogonally to the main body, the tubular portion internally defining a mounting hole receiving the clip therein.

Abstract: To secure both flexibility and rigidity of a pressure-receiving member, a pressure-receiving member capable of moving rearward in a state of receiving a load from a back of an occupant is included in a seat back of a conveyance seat for supporting the back of the occupant. The pressure-receiving member has a load-receiving portion which receives the load from the back of the occupant at a front face, and the load-receiving portion includes a load-receiving portion piece formed so that a length in a vertical direction of the seat back is shorter than a length in a seat width direction, and a rear reinforcement rib protruding along a thickness direction of the load-receiving portion from the load-receiving portion piece and extending along the seat width direction.

Abstract: Provided is a conveyance seat configured for adjustment of a deflection amount of a seat forming the conveyance seat, i.e., cushion properties of the seat. The conveyance seat includes a seat frame and a buffering body bridged over the seat frame configured to elastically support a seated occupant. The buffering body has a wire having both end portions attached to the seat frame, and a back restriction member configured to support at least a portion of the wire to restrict deflection of the portion of the wire. The wire includes a first right-to-left extending portion and a second right-to-left extending portion that extend in a seat right-to-left direction, and a coupling portion coupling the first right-to-left extending portion and the second right-to-left extending portion. The back restriction member is made of a resin material, and supports the first right-to-left extending portion and the second right-to-left extending portion.

Abstract: A cushion pan includes a front and rear support part that extends from the front end to the rear end of a seat cushion and faces the lower face of the femoral region of an occupant and side support parts that extend obliquely upward from both right and left side edges of the front and rear support part and face side faces of the buttocks of the occupant. In addition, the front and rear support part and the side support parts may be integrally formed to reduce the number of components and assembling steps.

Abstract: A seat for vehicles includes: a seat back frame; and a pressure receiving member that is mounted on the seat back frame to support a back of an occupant. The seat back frame includes a lower seat back frame and an upper seat back frame mounted on an upper portion of the lower seat back frame in a forwardly and rearwardly swingable manner, and the pressure receiving member is disposed from an area corresponding to the shoulder of an occupant to an area corresponding to the waist of the occupant and is supported by the upper seat back frame.
