The stepless adjusting means 2 configured as described above is
When the slide pipe 22 is lifted in the ascending direction, the lower end of the clamp chain 24 is pushed up against the spring force of a spring (not shown) of the clamp chain 24 by pulling up the slide piece 26, whereby the clamp chain 24 contracts. As a result, the engagement with the mandrel 23 is released, and the slide pipe 22 rises.

Since the mandrel 23 is locked by the clamp chain 24 in the descending direction, the slide pipe 22 is locked when the slide pipe 22 is raised and stopped. When the pipe 22 is pulled up and the lifting force is released, the pipe 22 is locked and fixed at that position.

Then, in order to lower the slide pipe 22, when the push knob 28 is pressed against the spring force of the spring 29, the operation pipe 25 is lowered in FIG.
As a result, the slider 27 moves downward to separate the clamp chain 24 and the mandrel 23, and thus the slide pipe 22 becomes slidable with respect to the guide pipe 21, so that the slide pipe 22 can be lowered. Become.

Reference numeral 4 denotes a mounting bracket fixed to the upper end of the slide pipe 22. The mounting bracket 4 has a bifurcated portion 41 at the upper side, and the pressing knob 28 projects from the center of the bifurcated portion 41. A headrest 3 having a pillow portion 31 and an upper surface portion 32 formed in an L-shape is rotatably attached to the forked portion 41, and the pillow portion 31 is automatically rotated to the front side in a raised position. The fulcrum position is determined as follows.

When the pillow portion 31 is rotated to the front side, the pillow portion 31 is moved forward by about 5 from the back portion 11 of the backrest 1.
By setting the fulcrum position to protrude by about cm, the head naturally comes into contact with the pillow portion 31 even when a stooped person such as an elderly person is seated, and therefore, is seated in a comfortable state. (See FIG. 4).

The bearing portion 42 is formed on the mounting bracket 4 at a position corresponding to the pressing knob 28, and a lock pin 5 having a tapered upper end is slidably supported on the bearing portion 42. At the same time, a spring 51 is stretched between the upper end of the slide pipe 22 and constantly urged upward, but the vertical movement range is regulated by a screw 52. Reference numeral 53 denotes a pin fixed to the upper end of the lock pin 5 to prevent the headrest 3 from tilting backward at a position where the headrest 3 is not used (the state shown in FIGS. 1 and 3). It is a pin.

Reference numeral 6 denotes a lifting lever fixed to the mounting bracket 4, which is formed in a T-shape as shown in FIG. Reference numeral 7 denotes a release lever for releasing the lock of the stepless adjusting means 2, one end of which is rotatably supported by the mounting bracket 4, and an intermediate portion formed with a hole 71 through which the lock pin 5 is inserted. The other end is bifurcated to form release knobs 72 located on both sides of the neck portion 61 of the lifting lever 6.

At the lower end of the lock pin 5 corresponding to the hole 71, a flange 54 is formed. When the release knob 72 is pressed down against the spring force of the spring 51, the lock pin 5
Descends and pushes down the push knob 28, whereby the lock of the slide pipe 22 by the clamp chain 24 is released, so that the headrest 3 can be lowered.

Reference numeral 8 denotes a support member mounted on the back surface of the backrest 1, and a pair of left and right support portions 81 rotatably supported on the mounting bracket 4, and an intermediate portion of the support portion 81. And the headrest 3 is in use (FIGS. 2, 4,
The lock piece 82 engaged with the tip of the lock pin 5 in the state (FIG. 5) and the upper end of the mounting bracket 4 in the use state prevent the headrest 3 from tilting too far forward, When the headrest 3 is not used (the state shown in FIGS. 1 and 3), an engagement piece 83 is formed which comes into contact with the pin 53 attached to the lock pin 5 and prevents the headrest 3 from tilting too rearward. ing.

Next, the operation of pulling out the headrest 3 based on the above-described configuration will be described. First, when the practitioner pulls up the lifting lever 6 by hand, the slide pipe 22 of the stepless adjusting means 2 is lifted as described above,
As a result, the slide piece 26 also moves up, so that the lower end of the clamp chain 24 is pushed up and the lock with the mandrel 23 is released. Therefore, the slide pipe 22 is raised, and the headrest 3 is raised.

When the headrest 3 rises and escapes from the concave portion 11a of the backrest 1, the pillow portion 31 rotates so as to fall forward from the fulcrum position of the headrest 3.
When the headrest 3 rotates, the upper end of the lock pin 5 raised by the spring 51 is engaged with the lock piece 82 of the support member 8 attached to the back surface of the headrest 3, and the engagement piece 83 is attached to the mounting bracket. 4 contacts the upper end.
Therefore, the headrest 3 is prevented from rotating backward, and the headrest 3 is also prevented from rotating forward, and a stable state is obtained.

In this state, when the lifting force by the lifting lever 6 is released, the clamp chain 24 returns to the engaged state with the mandrel 23 and becomes locked, so that the clamp chain 24 is attached. The slide pipe 22 is prevented from descending, so that the headrest 3 stops at a position where the hand is released from the lifting lever 6.

Next, the operation of lowering the headrest 3, which has been prevented from moving in the lowering direction, and storing it in the recess 11a of the backrest 1 will be described. First, when the release knob 72 is pressed down against the spring force of the spring 51, the release lever 7 lowers the lock pin 5, so that the lock pin 5 pushes down the push knob 28 located at the lower part.

When the pressing knob 28 is lowered, the operating pipe 25 to which the pressing knob 28 is fixed is lowered.
Slider 2 attached to the lower end of operation pipe 25
The slide piece 26 displaces the clamp chain 24 in the direction of shrinking via 7. Thereby, the clamp chain 2
4 releases the lock with the mandrel 23, so that the slide pipe 22 descends.

On the other hand, when the lock piece 82 of the headrest 3 and the lock pin 5 are engaged, the lock pin 5
2, the engagement state is released. Then, the slide pipe 22 is lowered, and the lowering of the slide pipe 22 is stopped at a position where the headrest 3 is stored in the recess 11 of the backrest 1. In this position, the engagement piece 83 of the support member 8 comes into contact with the pin 53 fixed to the slide pin 5,
The headrest 3 is prevented from falling backward too much.

[0031]

As described above, according to the present invention, the headrest is raised and stopped at a position where the headrest is locked by the stepless adjustment means. In this case, since the rearward rotation of the headrest is prevented, the operation of using the headrest can be performed safely without inadvertently rotating the headrest backward.

Also, when the headrest is in the raised state,
By allowing the rotation fulcrum position of the headrest to rotate naturally, one operation procedure by a practitioner can be omitted, and workability is improved. Further, in a use state in which the headrest is rotated forward, the operation of the headrest is prevented. By making the pillow part protrude forward from the back of the backrest, the subject can be relaxed without having to take an unreasonable posture even for a stooped person such as the elderly.
