Patent ID: 7243995

Claim:
A sear structure for a vehicle comprising: a seat disposed in a passenger compartment of the vehicle and including a seat cushion and a seat back, the seat being configured such that the seat back is capable of being folded on the seat cushion with its back facing upward; a vehicle-width-direction sliding mechanism disposed below said seat and guiding said seat so as to allow said seat to slide in a vehicle width direction, the vehicle-width-direction sliding mechanism comprising a pair of slide rails extending in the vehicle width direction respectively, which are disposed away from each other in a vehicle longitudinal direction, each slide rail comprising a lower rail and an upper rail; a vehicle-longitudinal-direction sliding mechanism guiding said vehicle-width-direction sliding mechanism so as to allow said vehicle-width-direction sliding mechanism to slide in a vehicle longitudinal direction in the passenger compartment of the vehicle, the vehicle-longitudinal-direction sliding mechanism comprising a pair of slide rails extending in the vehicle longitudinal direction respectively, which are disposed away from each other in the vehicle width direction, the slide rails of the vehicle-longitudinal-direction sliding mechanism guiding the lower rails of the slide rails of said vehicle-width-directior sliding mechanism, wherein said seat is configured so as to be guided in both vehicle width direction and vehicle longitudinal direction by said vehicle-width-direction sliding mechanism and said vehicle-longitudinal-direction sliding mechanism; a recess portion farmed at the bottom face of the seat cushion of said seat; and a moving mechanism disposed between said seat and said vehicle-width-direction sliding mechanism and moving the seat cushion of said seat forward and downward according to a movement of the seat back to be folded on the seat cushion, wherein a front slide rail of said vehicle-width-direction sliding mechanism, which is one of said pair of slide rails of the vehicle-width-direction sliding mechanism that is located on a front side, is configured such that a lateral length thereof is set shorter than a width of said recess portion in the vehicle width direction, whereby the front slide rail of said vehicle-width-direction sliding mechanism can be placed within said recess portion when the seat cushion of said seat has been moved forward and downward by said moving mechanism.
