Claim:
A vehicle seat, comprising: a seat main body having a seat cushion; a rotation mechanism that is arranged and constructed to horizontally rotate the seat main body with respect to a vehicle floor; a vertically moving mechanism that is arranged and constructed to vertically move the seat main body while moving the seat main body between vehicle interior and vehicle exterior; a seat support that is capable of attaching the seat main body to the vertically moving mechanism, and a first sliding mechanism that is arranged and constructed to horizontally move the seat main body, wherein a cushion frame of the seat cushion is composed of a pair of longitudinal side frame elements, an anchor frame positioned between the side frame elements, and anchor members attached to the anchor frame and capable of being detachably connected to a child seat, wherein the anchor frame is connected to the seat support via reinforcement members such that a force applied to the anchor frame via the anchor members can be transmitted to the seat support via the reinforcement members, wherein the vertically moving mechanism comprises a second lateral sliding mechanism that is disposed on a rotation base of the rotation mechanism, a vertically moving device that is attached to a slide base of the second lateral sliding mechanism, so as to vertically move depending upon the sliding motion of the slide base, wherein the seat support is slidably attached to the vertically moving device via the first sliding mechanism, so that the seat main body can vertically move while moving between the vehicle interior and the vehicle exterior when the vertically moving device is moved depending upon the sliding motion of the slide base, wherein a rear portion of the seat support is capable of engaging the slide base of the second lateral sliding mechanism when the seat main body is moved to a rear-most position in a condition that the slide base is in a retracted position, wherein the seat support is composed of a pair of longitudinal frame elements and a pair of front and rear lateral frame elements, wherein the front and rear lateral frame elements extend between the side frame elements of the cushion frame and are connected thereto, so that the cushion frame is integrated with the seat support, and wherein the anchor frame is connected to the rear frame element via the reinforcement members between the longitudinal frame elements.
