Abstract: The object of the invention is to provide a vehicle seat which can improve degree of freedom in the design of the vehicle seat.

Abstract: A car seat includes a first heater, a second heater, and a control unit which controls an output to the first heater and an output to the second heater. The control unit executes a temperature-difference adjustment control, in which the output of the second heater is controlled such that the temperature of the bulging portion heated by the second heater with respect to the temperature of the seating surface portion heated by the first heater is made lower when an ambient temperature is a first temperature than when the ambient temperature is a second temperature which is higher than the first temperature.

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.

Abstract: A seat backrest includes right and left side frame segments, a pressure receiving member disposed between the side frame segments movably in a front-back direction, and a cushion pad covering the front of the side frame segments and pressure receiving member. The pressure receiving member includes a main body part, and extending parts extending laterally from both sides of the main body part. The cushion pad includes a back receiving part covering the front of the main body part, and bank parts disposed on both sides of the back receiving part, protruding forward from both sides, and covering the front of the extending parts and side frame segments. A recess is formed at an area, facing a corresponding extending part of the extending parts, of a rear surface of each bank part.

Abstract: A vehicle seat (1) is provided with a cushion frame (5) that can be moved up and down by means of a link mechanism (6). To assist the upward movement of the cushion frame (5), a torsion bar (14) is disposed in a connection pipe (12) having both ends secured to a pair of left and right rear links (11, 11). A position holding member (24) holds the torsion bar (14) and is supported by the connection pipe (12), whereby the positional shift of the axis of the torsion bar (14) is suppressed. The position holding member (24) engages an extension portion (16) extending perpendicular to the shaft portion (15), and thus, does not rotate around the axis relative to the torsion bar (14). Therefore, in the position holding member (24), portions requiring reinforcement against a transverse force from the torsion bar (14) are limited a narrow range, and the position holding member (24) can be reduced in size and weight.

Abstract: A sensor disposition structure in a seat includes a cushion pad and a board-like member which is disposed under the cushion pad. A concave is formed in an upper surface of the board-like member, and a sensor is disposed in the concave.

Abstract: A passenger?s weight measurement device for a vehicle seat includes an upper rail provided on a lower rail that is fixable to a vehicle floor, the upper rail being movable in at least one of rear and front directions; a load sensor fixed onto the upper rail; and a frame provided on the load sensor and below the vehicle seat. In plan view, the load sensor protrudes from the frame in at least one of left and right directions.

Abstract: In order to suppress a claustrophobic feeling that a person sitting on a rear seat receives due to a front seat, and to make the front seat easy to use as an ottoman by the person, a movement adjustment system is used for a passenger seat and a rear seat, and includes a slide rail for moving the rear seat in the front to back direction, and a control part for changing the movement region of the rear seat by the slide rail. The passenger seat has a seat cushion, and a seat back mounted to be changeable between an upright state and a lowered state with respect to the seat cushion. The control part changes the movement region so that the passenger seat and the rear seat can come closer when the seat back of the passenger seat is in the lowered state than in the upright state.
