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

Vehicle seat

The number of components required to restrict the movement of an operating section, when a cushion frame is moved in the height direction, and a link member, which is for moving the cushion frame, is reduced. The seat is provided with: a drive link that is rotatably attached to the cushion frame and that moves the cushion frame in the height direction according to rotation thereof; a gear part that engages with the drive link and that rotates the drive link; a link-rotation restricting member for restricting the rotation range of the drive link; an operating section that accepts an operation for adjusting the height of the cushion frame; and a rotation application section for rotating the drive link via the gear part according to the operating section. The movement of the operating section is restricted as a result of the link-rotation restricting member abutting against the rotation application section.

Conveyance seat

A support structure stabilizes a position of a load measurement sensor by ensuring the rigidity of a support bracket supporting the sensor. The support structure supports the sensor, including an extension shaft portion extending from a sensor body, by each of attachment bracket and while the extension shaft portion is located at the lateral side of the sensor body, wherein each of the attachment brackets and includes an upright wall that is provided with an insertion hole into which the extension shaft portion is inserted when the sensor is supported, a bottom wall that intersects the upright wall and contacts the upright wall at one end in the seat width direction, and an upward protruding wall provided at a position contacting the bottom wall at the other end opposite the upright wall in the seat width direction of the bottom wall, intersecting the bottom wall, and facing the upright wall.

Load measurement sensor support structure

Provided is a support structure for a load measurement sensor having sufficient durability without adding a large load to a portion transmitting a load to the load measurement sensor. In the support structure, including a sensor body detecting a load generated from a seat having a seat frame and an extension shaft portion extending from the sensor body, to attachment brackets in a state where the extension shaft portion follows the horizontal direction, the support structure includes a load input portion which comes into contact with the sensor body and inputs a load to the sensor body. The sensor body includes a load receiving surface which comes into contact with the load input portion and receives the load, and the load input portion is formed to be movable in the axial direction of the extension shaft portion with respect to the load receiving surface.
