Abstract: A slider rail is provided in the back face of the seat back of a vehicle seat. The vehicle seat is formed of a framework having a plurality of frame members. The slide rail forms a guide path along which a slider is moved. The slide rail is attached outside the framework to a side portion (side frame member) of the seat back and extends in a longitudinal direction of the seat back, and overlaps with the side frame member in a front-rear direction of the vehicle seat.

Abstract: A seat for a vehicle includes a seat cushion frame reciprocating between seating and retracted positions, a seat back frame rotatable between standing and forward-tilted positions, a head rest movable between stationary and retracted positions, a pair of links provided at both end portions of the seat cushion frame on a floor in a lateral direction of the vehicle, a guide member including a guide groove extending between the seating and retracted positions, a slide member arranged at the seat cushion frame and sliding along the guide groove, a head rest retaining device retaining the head rest in the stationary position, a rotary member supported by the seat back frame and rotated by the slide member, and an interlocking device arranged between the rotary member and the head rest retaining device and releasing the head rest from the stationary position in accordance with a rotation of the rotary member.

Abstract: A lock mechanism for an electric retractable seat for a vehicle, includes a seat cushion frame, a seat back frame, a guide groove, a latch including an engagement opening portion, a slide member disengaging from the engagement opening portion when the latch is in an unlocked position, engaging with the engagement opening portion during a movement of the seat cushion frame to the seating position, and being locked between the guide groove and the engagement opening portion when the latch is in a locked position, a pawl for restricting the latch from pivoting when the pawl is in a restricted position, and allowing the latch to pivot when the pawl is in a released position, a releasing member for rotating the pawl.

Abstract: A slide rail has an opening allowing insertion and extraction of a slider. The slide rail has an opening. The cover member has an opening which overlaps opening. An open side corner surface of an inner peripheral edge portion of the opening of the slide rail is formed such that it has a rounded configuration. The inner peripheral edge portion with the rounded configuration is formed so as to extend in the direction of the center of the opening and beyond the opening of the cover member.

Abstract: A lock apparatus for a vehicle seat includes a protruding portion formed at the side of a seat cushion so as to protrude therefrom, the seat cushion being movable between a usable position and a retracted position, a guide wall member having a guide groove with which the protruding portion is engaged, a latch formed with an opening portion within which the protruding portion is engagable, a sliding member a sliding surface, a latch biasing member, a pawl, a cam surface formed at the pawl for rotating the latch so as to sandwich the protruding portion, a pawl biasing member, a releasing lever and a releasing member formed so as to protrude from the releasing lever in order to rotate the pawl by pressing a releasing portion in a direction against the biasing force applied to the pawl by the pawl biasing member.
