Patent ID: 7828358

Claim:
A storable seat for a vehicle comprising: an in-use position and a stored position that is movable in a front-rear direction via a link coupled pivotally in the front-rear direction, wherein the in-use position is a position at which a seat is fixed on a floor for a passenger to be seated thereon, and the stored position is a position at which the seat is stored in a concave portion formed in a part of the floor, wherein the seat is folded and stored at the stored position, wherein one end of the link is coupled to a coupling member fixed to the seat and the other end of the link is coupled to a coupling member fixed to the floor, wherein the link and the respective coupling members are coupled to each other with an axial member inserted into an insertion hole formed in at least one of the link and the respective coupling members, wherein the insertion hole is formed in at least one of a coupling portion of the link and the seat and a coupling portion of the link and the floor, and is formed in a shape that inhibits the axial member from undergoing positional displacement in the front-rear direction within the insertion hole when the seat is at the in-use position and allows the axial member to undergo positional displacement in the front-rear direction within the insertion hole as the seat is moved from the in-use position to the stored position, wherein the coupling portion, where the axial member is allowed to undergo positional displacement within the insertion hole, has a pivotal shaft and a guiding groove as the axial member to couple the link and the coupling member, wherein the pivotal shaft is a center of pivot of the link, wherein a guiding shaft is positioned apart from the pivotal shaft, wherein the coupling member is provided with an axial hole in which the pivotal shaft is inserted and the guiding groove in which the guiding shaft is inserted as the insertion hole, wherein the axial hole is a long hole whose front-rear dimension is larger than a diameter of the pivotal shaft, and wherein the guiding groove is formed in a shape conforming to a traveling trajectory of the guiding shaft and abuts on an outer surface of the guiding shaft in the front-rear direction when the seat is at the in-use position and a width dimension thereof becomes larger than the diameter of the guiding shaft as the seat is moved from the in-use position to the stored position.
