を第１図のように取付けると組立ては完了する。 Since the present invention has the above-mentioned configuration, the engagement holder 2 is attached to the upper part of the vehicle seat 1, and the elongated hole 1 is formed near the flange 13 of the engagement holder 2 as shown in FIG.
6, insert one bifurcated part 9'' of the engaging body 9 and position it as shown in Fig. 9, then move it to the position indicated by the dotted line.
The leg part 19 of the push button 18 is rotated 180 degrees and the spring 17 is fitted to the forked part 9'', which is formed separately.
Attach as shown in Figure 1 to complete the assembly.
これを車輛用シート１の上方から挿入して設
け、鍔部１３に止ネジ３，３′を挿入してねじ込
めば車輛用シート１に対して係合保持体２は装着
される。 The engaging holder 2 is attached to the vehicle seat 1 by inserting it from above the vehicle seat 1, and inserting and screwing the set screws 3, 3' into the collar 13.
この状態で、ヘツドレスト４の帯鋼製ステイ５
を挿入すると、帯鋼製ステイ５の下端部の両側は
テーパー状に切欠かれているので、係合部９′に

ずれか一個の係合凹部７，８と係合部９′が係合
して停止する。 In this state, the steel band stay 5 of the headrest 4
When inserted, both sides of the lower end of the steel band stay 5 are tapered, so when it comes into contact with the engaging part 9', the engaging part 9' is automatically moved to the surrounding area. Then, the steel band stay 5 enters and stops when one of the engaging recesses 7, 8 and the engaging portion 9' engage with each other.
この状態において、高さ調節するためにはヘツ
ドレスト４を持つて単に上動させればよい。その
ときは上向傾斜面１１の作用でプツシユボタン１
８を操作しなくても上動することができる。 In this state, to adjust the height, simply hold the headrest 4 and move it upward. At that time, the push button 1 is pressed by the action of the upwardly inclined surface 11.
You can move up without operating 8.
下動させるときは、係合部９′と下向水平面１
０が係合しているため、プツシユボタン１８を操
作して係合体９を包囲区域まで移動させなければ
下動しない。したがつて、少々の外圧ではヘツド
レスト４は下動しないので、安心して使用でき
る。 When moving downward, the engaging portion 9' and the downward horizontal surface 1
0 is engaged, the engaging body 9 will not move downward unless the push button 18 is operated to move the engaging body 9 to the surrounding area. Therefore, the headrest 4 will not move downward even with a small amount of external pressure, so it can be used with peace of mind.
また、帯鋼製ステイ５の構造は左右方向の帯鋼
のため、左右方向に対しては殆ど弾力を有しない
が、前後方向に対してはかなりのクツシヨン効果
があり衝撃を緩和する。 Further, since the steel band stay 5 is made of a horizontally oriented band steel, it has almost no elasticity in the left-right direction, but has a considerable cushioning effect in the front-rear direction and cushions the impact.
また、係合体９はピアノ線で形成されているの
で、単なる曲げ加工で製造でき、製造容易であ
り、コストも低廉ですませられる。 Furthermore, since the engaging body 9 is formed of piano wire, it can be manufactured by simple bending, making it easy to manufacture and inexpensive.
また、ヘツドレスト４を上方に勢いよく引抜い
ても係合部９′が上向水平面１１′に係合するので
抜け止めを防止する。 Further, even if the headrest 4 is pulled upward forcefully, the engaging portion 9' engages with the upward horizontal surface 11', thereby preventing the headrest 4 from coming off.

る。(Effects) The present invention provides a vertical cylinder 1 fixed to a vehicle seat 1.
2, a steel band stay 5 is vertically installed at the center of the lower surface of the head rest 4 from an upper position, and is inserted and removed freely. a plurality of engagement recesses 7 at intervals;
8, and an engaging body 9 that elastically engages with the engaging recess of the steel band stay 5 is provided on the vertical cylinder 12 side, of the engaging recesses 7 and 8.
Since the engagement recesses 7 except for the lowermost engagement recess 8 are recesses formed by the downward horizontal surface 10 and the upward inclined surface 11, the stays are not steel round bars but steel strips, so that the It has the effect of cushioning against impact.
また、上方への高さ調節は、ヘツドレスト４を
持つて単に上動させればよく、上向傾斜面１１の
作用でプツシユボタン１８を操作しなくても上動
させることができる。 Further, to adjust the height upward, it is sufficient to simply hold the headrest 4 and move it upward, and by the action of the upwardly inclined surface 11, the upward movement can be made without operating the push button 18.
また、最下段の係合凹部８は下向傾斜面１０′
