【考案の詳細な説明】
本考案は車両用特に自動車用座席の背もたれ頂
部に設けたヘツドレストの高さ調節装置に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a height adjusting device for a headrest provided at the top of a backrest of a vehicle seat, particularly an automobile seat.
一般に自動車等の座席に設けられる上下調節可
能なヘツドレスト装置は、ヘツドレストの固定と
上下調節を背もたれに設けたホルダーとヘツドレ
ストのステイとの摩擦係合により行なつていた
が、上下調節が摩擦力に抗して行なわれるため、
摩擦力を小さくして操作を軽くしようとすると、
ヘツドレストの保持力が弱くなり、乗員の頭部に
よる衝撃で容易に押し下げられるため安全性に問
題があつた。また摩擦力を大きくした場合は操作
性が悪くなるため、このような摩擦力による上下
調節装置では操作性と安全性を満足することが困
難であつた。 Generally, vertically adjustable headrest devices installed in automobile seats fix the headrest and adjust it up and down by frictional engagement between a holder installed on the backrest and the stay of the headrest. Because it is done against
If you try to reduce the frictional force and make the operation easier,
The holding power of the headrest was weakened and it was easily pushed down by the impact of the occupant's head, posing a safety problem. Furthermore, when the frictional force is increased, the operability deteriorates, so it has been difficult to satisfy operability and safety with such a vertical adjustment device using the frictional force.
なお、前記不具合を除去するものとして本願出
願人の出願に係る考案（実開昭57−27956号公報）
が開示されている。これはホルダーにステイの軸
方向にノブを有する弾性板体を軸着し、この弾性
板体に設けた係止部が弾性板体の弾性によつてス
テイの係合孔に係合するようにしたものであり、
ノブはステイに対して接離方向に略水平状に移動

除する構造である。 In addition, as a method for eliminating the above-mentioned defects, the invention related to the application of the present applicant (Utility Model Application Publication No. 57-27956)
is disclosed. In this method, an elastic plate having a knob is attached to the holder in the axial direction of the stay, and the locking part provided on the elastic plate is engaged with the engagement hole of the stay by the elasticity of the elastic plate. and
The knob is structured to move substantially horizontally toward and away from the stay, thereby rotating the elastic plate and disengaging the locking portion from the engagement hole of the stay to release the locked state.
従つて、これはノブを略水平状に押圧しなけれ
ばならないが、このノブはステイの近傍に配設さ

ダーの上部にノブが移動できるための空間を設け
なければならず、その空間に外部から異物が挿入
されると、ノブの操作が困難になる欠陥がある。 Therefore, it is necessary to press the knob almost horizontally, but since this knob is located near the stay, not only does the stay get in the way, making it difficult to operate the knob, but also Since the knob and the elastic plate are integrated, there is a problem that the locked state cannot be released unless the knob is moved a large amount. Additionally, if the amount of movement of the knob is increased, a space must be provided at the top of the holder for the knob to move, and if a foreign object is inserted into that space from outside, the knob may become difficult to operate. .
本考案は上記欠点に鑑みこれを改良したもの
で、操作ノブによりヘツドレストのステイを確実
に係止し、かつ操作ノブの押圧により係止を解除

提供するものである。 The present invention has been improved in view of the above-mentioned drawbacks, and provides a headrest device in which the stay of the headrest is reliably locked by an operating knob and can be easily moved up and down by releasing the locking by pressing the operating knob. It is something to do.

る。 Hereinafter, the operating state of the headrest height adjusting device according to the present invention will be explained. First, the state in which the headrest is held at a predetermined height is shown in FIGS. 3 to 5. That is, the lock spring 16 is fitted into the slit 10 of the support portion 5, and the locking pieces 18 of the lock spring 16 are engaged with the sliding portion 15 of the adjustment plate 13 and the locking groove 8 of the stay 7, respectively. death,
Further, the fixing piece 17 of the lock spring 16 is engaged with the engagement recess 14 of the adjustment plate 13 and the vertical hole 11'. Therefore, since the locking piece 18 of the lock spring 16 disposed on the side of the support portion 5 engages with the locking groove 8 of the stay 7, vertical movement of the stay 7 is restrained.

置に調節し得る。 When the operating knob 12 is pressed in this state, the adjusting plate 13 integrated with the operating knob 12 moves downward. Along with this movement, the engagement recess 1 of the adjustment plate 13
The fixing piece 17 of the lock spring 16 that is engaged with the lock spring 16 is inserted into the vertical hole 1 while being engaged with the engagement recess 14.
It descends within 1'. As the fixing piece 17 of the lock spring 16 descends, an upward elastic force is generated against the adjusting plate 13. On the other hand, the locking piece 18 of the lock spring 16 is pushed out of the locking groove 8 of the stay 7 by the slope of the sliding portion 15 of the adjustment plate 13 and moves laterally along the slit 10 of the support portion 5. Therefore, the headrest 3 can be moved up and down, and the height of the headrest 3 can be adjusted to a desired position.

い。 As described above, in the present invention, a lock spring is disposed perpendicularly to the stay in a holder that is integrally provided with a guide tube through which the stay of the headrest is inserted and a support part, and one end of the lock spring is fitted into the support part. This is a headrest height adjustment device that comes into contact with the sliding part of the operating knob, and when the operating knob is pressed, the lock spring is rotated to engage and release the headrest stay. The headrest can be moved up and down and securely fixed in any position, providing excellent safety. Furthermore, since the locking of the headrest and the return of the operating knob can be performed with a single spring, the number of components is small, the mechanism is simple, and the assembly is easy, so it can be manufactured at low cost. In addition, in the present invention, the engagement of the lock spring with the stay can be released by pressing the operating knob downward, so that the operability of releasing the lock is excellent. In addition, since the lock spring and the adjustment plate of the operation knob are formed separately,
The amount of movement of the stay in the lock spring in the direction of the locking groove can be increased. Therefore, the locking groove of the stay can be formed deep, and the lock spring is directly connected to the locking groove perpendicularly to the stay.
The locked state is ensured. Furthermore, since the operating knob is fitted into the recessed portion of the holder, foreign matter from the outside does not enter the slit inside the holder.
