Abstract:
1. A seat for a vehicle, comprising: a seat cushion frame adapted to be moved in a reciprocating manner between a seating position and a retracted position and to support a seat cushion; a seat back frame adapted to be rotated between a standing position and a forward-tilted position and to support a seat back; a head rest supported at an upper end portion of the seat back frame and movable between a stationary position and a retracted position; a pair of links provided at both end portions of the seat cushion frame in a lateral direction of the vehicle, one end of each link being adapted to be pivotably connected to a vehicle floor and the other end of each link connected to a front portion of the seat cushion frame; a guide member arranged at the vehicle floor and including a guide groove formed to extend between the seating position and the retracted position of the seat cushion frame; a slide member arranged at a rear end portion of the seat cushion frame and slidably engaging with the guide groove; a head rest retaining device retaining the head rest in the stationary position; a rotary member rotatably supported by the seat back frame and rotated by the slide member sliding along the guide groove of the guide member; and an interlocking device having a first end connected to the rotary member so that rotation of the rotary member moves the interlocking device and a second end connected to the head rest retaining device so that movement of the interlocking device moves the head rest retaining device to permit the head rest to move toward the retracted position of the head rest, and wherein movement of the seat cushion frame towards the retracted position rotates the rotary member and causes movement of the interlocking device which moves the head rest retaining device to release the head rest from the stationary position and allows the head rest to move toward the retracted position.
