The pressure sensor and the openings are spaced from the front edge of the main body.

Vehicle seat having internal support member

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.

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.

Conveyance seat

A mat attachment structure of a seatback includes: a guide wire attached to the mat and provided, at the distal end part, with a straight portion extending in a longitudinal direction of the seatback frame on a tip side of the seatback frame or its root side; and a through-hole formed in the seatback frame and through which the straight portion is insertable. The through-hole is provided with a protruding part which includes a high protruding portion and a low protruding portion formed adjacent to the high protruding portion. In a first movement of the mat, the straight portion moves in a de-insertion direction while coming into contact with the high protruding portion. As the amount of movement of the mat gets larger than the amount of movement of the first movement, a contact position between the straight portion and the protruding part moves toward the low protruding portion.

Mat attachment structure of seatback and vehicle seat

A mat attachment structure of a seatback includes: a guide wire attached to the mat and provided with a width-direction extending part extending in s width direction of the seatback frame on a tip or root side of the seatback frame; and a holder having a base part which holds the width-direction extending part so as to be rotatable around an axis of the width-direction extending part and an attachment part attached to the seatback frame. When a force exceeding a predetermined value in a direction to separate from the seatback frame is applied from the width-direction extending part to the holder, the force being due to the force from the back of the occupant that the mat receives, the width-direction extending part departs from the base part or the holder departs from the seatback frame, so that the width-direction extending part is separated from the seatback frame.

It is intended to expand a space at a back portion of a lower portion of a seat.
