If the front end of the long hole in the rail piece on the board side touches the horizontal pin on the base frame side and the stop knob is fixed, the backrest will stand up and become a normal seat, and the long hole on the rail piece will be moved forward relative to the horizontal pin. If you move the stop knob appropriately and fix it, the backrest will tilt and become a reclining chair.Also, loosen the stop knob and disengage it from the notch in the rail piece.
By tilting your body backwards and standing up, it becomes a health device for bending and stretching your body while sitting.At that time, if you flip the backrest and touch the acupressure to your back and waist, and perform body bending and stretching exercises, you can perform acupressure. The child will receive acupressure massage from the lower back to the back and nape of the neck.

(Embodiments) Hereinafter, embodiments of this invention will be described with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a base frame that is U-shaped in plan and has both side rods 1a bent forward and upward at the rear, and the upper ends of the rear bent portions 1b are located midway between the support rods 4 of the backrest 3. It is rotatably attached to a rearward protruding piece 4a provided (however, this protruding piece 4a is not necessarily necessary, and the bent portion 1b may be pivoted directly to the support rod 4), and the left and right support rods are 4 are connected by a connecting rod 5, the upper end of each support rod 4 is rotatably attached to the center of both sides of the backrest frame rod 3a, and the lower end of each support rod 4 is connected to the seat frame rod 2a of the seat 2. are rotatably attached to the rear of both sides.

Further, upright pieces 6 are provided at positions near the front ends of both side rods 1a of the base frame 1, and rail pieces 7 are respectively attached to the front portions of both sides of the seat frame rod 2a opposite to them, and each rail As seen in FIG. 3, the piece 7 has a groove shape in the form of a letter 7 in cross section, and the long outer piece is provided with a horizontal elongated hole 7a, and several notched recesses 7b are formed at its lower end. Each upright piece 6 of the base frame 1 is provided with horizontal pins 6a and screw holes 6b above and below, and the horizontal pins 6a are connected to the elongated holes 7 of the rail piece 7.
rollers 8 are rotatably attached to the tips of the rollers 8, which engage with the grooves of the rail piece 7, and the screw holes 6b can freely engage with the notched recesses 7b of the rail piece 7. The screw rod of the stop knob 9 is screwed together.

In addition, the backrest 3 has a cushion material 3b placed on a frame rod 3a made of pipes etc. as usual, and the whole is covered with a cover 3c.
On the back surface of the backrest 3, two hemispherical acupressure elements 10 are arranged on the upper and lower sides toward the rear, and are attached to a vertical rod at the center of the frame rod 3a.

Based on the above configuration, if the stop knob 9 is loosened and the seat 2 is moved back and forth, the rail pieces 7 on both sides of the lower surface will also fit into the elongated hole 7a, the horizontal pin 6a, and the groove and the roller 8. Therefore, it moves back and forth relative to the upright pieces 6 on both sides of the base frame 1, and as a result, the support rods 4 pivotally supported on both rear sides of the seat 2 move around the bending part 1b and the pivoting part of the base frame 1. rotates back and forth as
The backrest 3 tilts and stands up appropriately.
