ックする装置は公知である。(Prior art) The backrest seat side mounting bracket is attached to the seat side mounting bracket a so that it can rotate freely back and forth through an axis C, and the sector gear plate is mounted on the backrest seat side mounting bracket with rivets (d). e is fixed, a lock plate g that engages with the sector gear f of the sector gear plate e is pivoted on the side of the seat individual mounting bracket a, and a shaft i is provided near the lock plate g. axis i
Lock the latch j and operating lever k, and lock the lock plate g.
A device for locking the backrest seat side mounting bracket by pressing the latch j is known.
（発明が解決しようとする問題点）
公知の構造は、背凭シート側取付金具すを前倒しにした
のち、これを引起したとき、起立状態を越えて後倒れに
なることがある。このことを、歯飛びという。(Problems to be Solved by the Invention) In the known structure, when the backrest seat side mounting bracket is tilted forward and then raised, it may exceed the upright state and fall back. This is called tooth skipping.

倒れとなるが、このとき、操作レバーには上動したまま
の状態となる。That is, when the operating lever k is moved upward from the position indicated by the phantom line to the position indicated by the solid line in Fig. 3, the protrusion A, which is engaged with the engagement hole m in the operating lever, is moved downward, and the latch j and lock are moved. Disengaging plate g and moving lock plate g a little to the left in the drawing will disengage lock plate g and sector gear f, causing the backrest seat side mounting bracket to fall forward. At this time, the operating lever remains in the upward position.

てしまうのである。Therefore, if the backrest seat side mounting bracket is carefully raised up around the axis C, the latch J will also return to its original position in order for the lock plate g to engage with the sector gear f. Since it has to return to its original position and takes time due to inertia, lock plate g and sector gear f
(1) The fit is delayed, causing a tooth-skipping phenomenon, and the backrest seat-side mounting bracket jumps over the standing position and falls down onto the rear seat.

The latch 10 is rotated clockwise by moving the protrusion 15 downward by the inner circumference of the upper part of the latch 10 to release the engagement between the latch 10 and the lock plate 8. At the same time, the pin 13 is moved by the cam groove 14 and the lock plate 8 and the sector gear 6 are moved. However, since the elongated hole 16 is formed, when the operator releases the operating lever 11, the operating lever 11 returns to its original position by the spring 18.

、公知例の操作レバー１１の慣性を防止できる。Therefore, the backrest seat side mounting bracket 3 is in the forward tilted position due to the engagement and disengagement between the sector gear 6 and the lock plate 8 (
(Fig. 2), when the back seat side mounting bracket 3 is raised in this state, the lock plate 8 slides on the toothless part of the sector gear plate 5 and moves to the position where the sector gear 6 is located.
Becomes a standing state. Immediately, the latch 10 presses the lock plate 8 against the sector gear 6 by the action of the spring 17, so the lock plate 8 reliably engages with the sector gear 6 and does not cause tooth skipping. Since the operation lever 11 does not rotate due to the presence of the elongated hole 16, the inertia of the known operation lever 11 can be prevented.
