Claims

[Scope of Claim for Utility Model Registration] 1. An adjustment device for adjusting the longitudinal position of an automobile seat and the angle of the seat back, which locks the seat back by pivoting approximately in the vertical direction about a predetermined fulcrum. and a lock lever that switches to the open state, and a lock lever that is fixed to the vehicle body side.
A locking member having a plurality of locking portions arranged in the front-rear direction, and a position where the locking member engages with the locking portion and a position where the locking member disengages from the locking portion can be rotated toward the seat side. A locking member attached to the lock lever, a slide member attached to the lock lever so as to be slidable in the front and back directions, and a locking member attached to the lock lever at a position on the seat side that abuts both the slide member and the locking member around a substantially vertical axis. a cover that is rotatably attached to and has a rotating member that converts the longitudinal movement of the sliding member into rotation of the locked member; and a through hole for exposing a part of the sliding member to the outside. The through hole is characterized by comprising a first groove formed in correspondence with the rotation locus of the slide member and a second groove formed in correspondence with the slide movement locus of the slide member. An adjustment device for automobile seats. 2. A lock lever which is an adjustment device for adjusting the longitudinal position of an automobile seat and the angle of the seat back, and which switches the seat back between a locked state and an open state by rotating in a substantially vertical direction about a predetermined fulcrum; Fixed to the vehicle body side,
A locking member having a plurality of locking portions arranged in the front-rear direction, and a position where the locking member engages with the locking portion and a position where the locking member disengages from the locking portion can be rotated toward the seat side. A locking member attached to the lock lever, a slide member attached to the lock lever so as to be slidable in the front and back directions, and a locking member attached to the lock lever at a position on the seat side that abuts both the slide member and the locking member around a substantially vertical axis. a rotating member that is rotatably attached to the seat and converts the longitudinal movement of the slide member into rotation of the locked member; and a rotating member that is fixed to the seat side;
When the slide member slides in the direction of releasing the engagement between the locked member and the locking portion, the rotation restriction piece that blocks the movement path of the slide member in the rotation direction and the slide member release the seat back. 1. An adjustment device for an automobile seat, comprising: a regulating member comprising a slide regulating piece that blocks a movement path of the sliding member in the sliding direction when the sliding member is rotated in a direction to change the state.
