Description

  The present invention relates to a vehicle seat.

Generally, a seat cushion of a vehicle seat is configured to be movable up and down so that the height of a seating surface can be changed and adjusted in accordance with the physique of an occupant. Further, the vehicle seat is provided with a side cover that covers the lower side of the seat cushion.
In such a structure, the vertical gap between the seat cushion and the side cover is enlarged and reduced as the seat cushion is raised and lowered. If the internal mechanism below the seat cushion is seen through this gap, it will not look good. In particular, when the gap is enlarged, the internal mechanism can be easily seen. Therefore, the gap needs to be reliably shielded between the reduced state and the enlarged state.
Therefore, conventionally, the technique disclosed in Patent Document 1 has been proposed. In this technique, the side cover is divided into an upper part and a lower part that are fixed in position and an upper cover that moves up and down by the operation of the lifter mechanism. Further, the upper part of the lower cover and the lower part of the upper cover overlap each other in the seat width direction. And the overlap margin of the upper part of a lower cover and the lower part of an upper cover is set so that the overlapping state of the upper part of a lower cover and the lower part of an upper cover may not be cancelled | released in the full raising / lowering stroke of an upper cover.
