Abstract: A vehicle seat includes a base part, a first movable part, a second movable part, a lock member, and an interlocking mechanism configured to link movement of the lock member to movement of the second movable part. The interlocking mechanism includes an attaching member, a first rotational member connected to the second movable part, a second rotational member connected to the lock member, and a swingable member provided swingably on the second rotational member. The engagement of the swingable member and the first rotational member causes the first rotational member and the second rotational member to rotate together, whereby the lock member moves from a lock position to an unlock position. The swingable member disengaging from the first rotational member permits the first rotational member and the second rotational member to rotate independently, whereby the lock member moves from the unlock position to the lock position.

Abstract: Rigidity is improved at a part where side frame pieces overlap each other in a side frame. In a vehicle seat provided with a seat back frame, a side frame of the seat back frame has a first side frame piece and a second side frame piece partially overlapping each other in a direction of extension of the side frame. The side frame has an overlapping part where both the first side frame piece and the second side frame piece overlap each other. At the overlapping part, the side frame pieces overlap each other in a state where a plurality of closed regions and closed by being surrounded by both side frame pieces are formed in a cross section of the overlapping part intersecting with the direction of extension of the side frame.

Abstract: Rigidity is improved at a part where side frame pieces overlap each other in a side frame. In a vehicle seat provided with a seat back frame, a side frame 10 of the seat back frame has a first side frame piece 20 and a second side frame piece 30 partially overlapping each other in a direction of extension of the side frame 10. The side frame 10 has an overlapping part 40 where both the first side frame piece 20 and the second side frame piece 30 overlap each other. At the overlapping part 40, the side frame pieces overlap each other in a state where a plurality of closed regions 41 and 42 closed by being surrounded by both side frame pieces are formed in a cross section of the overlapping part 40 intersecting with the direction of extension of the side frame 10.

Abstract: A vehicle seat comprises a frame member, a plate-shaped support member, and a blower. The frame member includes a pair of opposed frames disposed opposite to and separately from each other, and a first connecting frame by which the pair of opposed frames are connected. The plate-shaped support member is disposed between the pair of opposed frames and configured to receive a load from an occupant. The blower is attached to the support member, and part of the blower is disposed on a side of the first connecting frame that is opposite to an occupant side thereof.

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.
