1 is a lower bracket fixed to the seat part, 2 is an upper bracket fixed to the backrest part, which is fixed by a shaft 13, and either the lower bracket 1 or the upper bracket 2 has a recess 3 on the outer peripheral surface. A latch 4 is provided, and a ratchet 6 having a pawl 5 that engages with the recess 3 is rotatably attached to one of the latch 4 by a shaft 7.
前記ラッチ４の外周縁は軸１３を中心とする円弧縁に形
成・される。The outer peripheral edge of the latch 4 is formed into an arcuate edge centered on the shaft 13.
前記ラチェット６は軸７より放射方向に伸びるアーム部
８と、該アーム部８の先端部よりラッチ４方向に曲って
形成される爪部５とから形成される。The ratchet 6 is formed of an arm portion 8 extending radially from the shaft 7, and a claw portion 5 bent from the tip of the arm portion 8 in the direction of the latch 4.
爪部５の形状は、軸７の軸心を中心とする小径の半径ｒ

とにより「成される。The shape of the claw portion 5 is a small radius r centered on the axis of the shaft 7.
an inner edge 9 on the side closer to the axis 7 along the axis 7, and an outer edge 10 on the side farther from the axis 7 along the large radius R centered on the axis of the axis 7.
“It will be accomplished.”
しかして、前記凹部３に接続する無歯部１２の後側には
ストッパー１４を形成する。すなわち、前記爪部５の内
縁９が凹部３に達したとき、前記爪部５の外縁１０の先
端部１５が当接するストッパー１４を設けておく。Thus, a stopper 14 is formed on the rear side of the toothless portion 12 that connects to the recess 3. That is, a stopper 14 is provided, with which the tip 15 of the outer edge 10 of the claw portion 5 comes into contact when the inner edge 9 of the claw portion 5 reaches the recess 3.
（実施例二）

１４の高さは低い。(Embodiment 2) In FIG. 4, the tip edge 11 of the claw portion 5 is formed into an arcuate surface that follows the arc of the outer periphery of the latch 4 while being in contact with the outer periphery. Therefore, since no gap is formed between the toothless portion 12 and the tip portion 15 as in the embodiment, the height of the stopper 14 is low.
（作用） 次に作用を述べる。(effect) Next, we will discuss the effect.
本発明は前記の構成のため、下記に述べるような作用を
奏する。Because of the above configuration, the present invention exhibits the following effects.
公知の如く、背凭部が前倒れの状態では、ラチェット６
の爪部５はラッチ４の無歯部１２上に当接している。As is well known, when the backrest is tilted forward, the ratchet 6
The claw portion 5 is in contact with the toothless portion 12 of the latch 4.
この状態で、背凭部を引き起すと、爪部５は無歯部１２
を摺動して、爪部５の内縁９が、無歯部１２から外れる
瞬間、勢い余って歯爪を成す状態になるが、本発明は、
そのとき−瞬早く、外縁１０の先端部１５を無歯部１２
に形成されているストッパー１４に当接させて、歯爪を
防止する。In this state, when the backrest is pulled up, the claw part 5 will move to the toothless part 12.
At the moment when the inner edge 9 of the claw part 5 is removed from the toothless part 12 by sliding, the force becomes excessive and forms a toothed claw.
At that time - in an instant, the tip 15 of the outer edge 10 is connected to the toothless part 12.
It is brought into contact with a stopper 14 formed in the top to prevent tooth claws.
第二実施例も作用は同一である。The second embodiment also has the same effect.

A ratchet C having a pawl d on the other side is fixed by an axis e, the outer peripheral edge of the latch a is formed into a circular arc edge centered on the axis f, and the inner edge g and the outer edge of the pawl d are It has been known to form concentric circles with radii r and H centered on the axis e, respectively. However, in the known one, when the ratchet c is rotated and the claw d is pulled out of the recess, the inner edge g moves with a radius r and the outer edge moves with a radius R, so the difference in radius causes , the outer edge moves more greatly, and a gap is formed between the tip i of the outer edge and the toothless part j on the rear side following the recess, and it becomes in a lifted state.
そのため、背凭部を引起すとき、歯飛び現象を生じた。Therefore, when the backrest was pulled up, a tooth skipping phenomenon occurred.
