[0005]

Embodiments of the present invention will be described below. In the first embodiment, the air mat (2) bulges into an L shape when air is injected from the air inlet. The seat (15) is spread out, and set and mounted on a seat (60) of a car. Then, the seat belt (61) is inserted into the seat belt through holes (19) (20) provided in the seat (15).
The seat (15) is fixed to the seat (60).
The air mat (2) is fixed to the seat (15) with the fixing band (7). See FIG. 5 and FIG.

When attaching the small child (63) to the air mat (2), the button (62) of the Y-shaped band (8) and the band (11) supporting the shoulder are removed. Also, remove the chuck (9) of the abdominal support band (10) and remove the abdominal support band (1).
0) is opened on both sides, the child (63) is placed on the air mat (2), and the abdominal support band (10) is closed with the chuck (9). Next, a button (62) provided on the abdominal support band (10) by passing the Y-shaped band (8) through the inside of both feet.
Stop with Further, the band (11) for supporting the shoulder is lowered below the shoulder and stopped with the button (62) provided on the abdominal support band (10). The small child (63) is fixed to the air mat (2) as described above. The head is held by a headrest mat (12). When not in use, place the air mat (2) in the chair (1
5) The air can be removed and the air can be removed so that it can be folded small. In addition, the seat (15) can be folded down by removing the seat belt (61) and folding the backrest (17) forward so that it can be folded and stored easily, and can be put in the trunk of a small car. You can put it away. See FIG. 1, FIG. 2, FIG. 5, and FIG.

The angle of the seat (15) can be lowered by lowering the lever (30) so that the projection (29) is formed in the stopper groove (26).
It can be fixed at any angle because it deviates more. Lever (3
0) is always pressed by the spring (32), so that it does not come off unless the lever (30) is lowered. See FIG. 7 and FIG.

The height adjustment and the angle adjustment in front of the seat (15) can be easily adjusted by turning the adjustment shaft (39) as shown in FIG.

When adjusting the height or angle of the front of the seat (15), the notch groove (44) provided in the shaft (43) is deepened downward as shown in FIG.
By turning and tightening 8), the shaft (43) is fixed, and by loosening, the shaft (43) can be raised freely.

A one-way rotating clutch (50) shown in FIG. 11 shows one embodiment, and is also called a one-way clutch or a cam clutch, which means a clutch that rotates in one direction. When the backrest (17) of the seat (15) is tilted rearward, the inner ring (51) and the shaft (14) are fixed, and the inner ring (51) has a hexagonal shape. 64) moves to the left as indicated by the imaginary line, and the ball (64) freely rotates clockwise without biting the inner ring (51) and the inner circumference of the outer ring (52). Therefore, when the backrest (17) is tilted backward, the teeth (54) of the pawl (55) can be freely tilted by removing the teeth (54) from the ratchet groove (53). The outer ring (52) is fixed to a shaft support (22). Conversely, the back part (17)
If you try to tilt the ball forward, the ball (64)
And the inner periphery of the outer ring (52) is a cam mechanism, the ball (64) of the inner ring (14) does not rotate to the left, and the backrest (17) falls forward. Safe without any. When tilting the back part (17) forward, moving the lever (66) to the right moves the ball (64) to the left, so that the ball (64) does not bite, so the inner ring is free to move to the left. Because it rotates, the backrest (17)
Can be knocked forward freely. When the lever (66) is released, the retainer (67) is pulled by the spring (65) and the ball (6) is released.
4) moves to the right, and the ball (64) does not bite and fall forward. Therefore, the backrest (1
The angle of 7) can be set arbitrarily.

As shown in FIG. 12, the backrest (17)
Since the angle adjustment is performed by the adjustment bolts (58) and (58), the angle adjustment is secure, and does not come off.

As shown in FIG. 13, an air pillow (5
9) is to adjust the height and angle by injecting and extracting air.

FIGS. 14 and 15 show fixed clutch teeth (7
In 2), the clutch teeth (73) are engaged, and the backrest (17) is fixed and does not move. To move the backrest (17) forward or backward, turn the tightening adjustment nut (78), loosen it, and move the angle of the backrest (17) to push the clutch teeth (73) outward. Then, the angle of the backrest (17) can be freely adjusted. When the clutch teeth (73) come off, the spring (7
Since the button is pushed in step 6), a clicking sound is generated and the clutch teeth (73) are constantly pressed, so that the backrest (17) does not suddenly become free and fall down. . When the angle of the backrest (17) can be adjusted, the tightening adjustment nut (78) is tightened and the clutch teeth (7) are adjusted.
3) Engage the backrest (17).
