Abstract: A vehicular seat slide adjuster has a lower rail fixed to a vehicle body and an upper rail to which a seat cushion frame is attached, the upper and lower rails being engaged with each other in sliding relation. The lower rail includes a vertical wall portion, upper and lower horizontal wall portions projecting from respective edges of the vertical wall portion, and flange portions extending downwardly from respective ones of the horizontal wall portions. The upper rail includes a vertical wall portion opposing the vertical wall portion of the lower rail in spaced relation, horizontal wall portions opposing the horizontal wall portions of the lower rail in spaced relation, and flange portions opposing the flange portions of the lower rail.

Abstract: There is disclosed a device for uniformly stretching the skin of a seat of an automobile. The device has L-shaped projection portions mounted on the frame of the seat. Retaining members that engage the projection portions are disposed or formed on the fringe of the skin at intervals. The projection portions have flanges extending at right angles to the direction in which the skin is stretched. Notched portions are also provided on the frame adjacent to the projection portions. The retaining members have step portions that engage the flanges and notched portions of the frame.

Abstract: A seat mounted on a vehicle floor comprising a seat frame and a backrest. The seat frame contains a plastic base member and an open section formed within the base member. The base member is circumscribed by a rim extending upward along a substantial portion of the base member and a support surface extending outward from the base member substantially perpendicular to the rim. The base member contains a plate section integrally connected to the base member and extending within the open section. A device is provided for adjustably supporting the seat frame along the floor of the vehicle. A pair of support rods are connected to the adjustable support device and the seat frame is mounted on the support rods. A device is also provided for flexibly supporting the plate section in response to downward pressure thereon. A seat cushion is mounted on the seat frame. The backrest, which is connected to the seat frame, includes a fixed backrest frame having sidewalls extending outward from the backrest frame.
