Claims

[Scope of utility model registration request]

A seat portion of a seat having a backrest portion that can be tilted forward is fixed to a movable rail that is slidably provided along a fixed rail fixed to the vehicle body, and a plurality of lock plates are attached to the side surface of the lock plate fixed to the fixed rail side. engaging holes are arranged and drilled in the longitudinal direction of the fixed rail, and a memory portion consisting of a lower edge and a higher edge is formed on the upper edge of the lock plate, and the lock plate is pivotally supported on the movable rail side. A locking claw that can selectively engage and disengage one of the engagement holes is fixed to an operating shaft parallel to the movable rail, and a locking claw that engages with a portion of the locking claw when the backrest of the seat is tilted forward. At the same time, a retaining member linked to the backrest portion is pivotally fitted so that the locking pawl is rotated in a direction in which the locking pawl is disengaged from the engaging hole, and the locking pawl is biased in a direction in which the locking pawl is engaged with the engaging hole. A spring is provided between the movable rail and the operating shaft or the lock pawl, and the base of the locking lever is disposed above the memory part of the lock plate so as to intersect with the memory part, and the base part of the locking lever is placed on the movable rail side. The locking lever has a locking lever that can swing freely in the vertical direction and is pivotally mounted with the tip end biased downward, so that the tip of the locking lever can come into contact with the engaging portion formed on the retaining member. When located at the locking position, the retaining member is restrained at the retaining position where the locking claw is completely disengaged from the engagement hole, and the tip of the locking lever is disengaged above the engaging portion of the retaining member. When the seat is in the inoperative position, the restraint of the retaining member to the retaining position is released, and when the seat is in a rearward position from the predetermined standard position, the memory unit is released from the high position. A seat slide device for an automobile, characterized in that the positional relationship between the locking lever and a higher edge of the memory portion is determined such that the locking lever is restrained in an inoperative position by the edge.
