Then, the lower side of the other link 2b is pivotally supported.

The X-shaped links 5a and 5b are provided above the links 2a and 2b.
The lower side is pivotally attached, and the upper side of one of the links 5a and 5b is pivotally supported on the base 6, and the slider 8 sliding on the rail 7 provided on the base 6 is connected to the other link 5b. Support the upper side of.

A cylinder 9 is installed between the floor base 1 and the link 5a.

When the cylinder 9 contracts, the X-shaped links 2a, 2
Although the relative angle between b and 5a, 5b becomes smaller, the base 6 descends, but when the cylinder 9 extends, the links 2a, 2b
The relative angle of b, 5a, 5b increases, and the base 6 rises.

A waist plate 11 is pivotally supported on the base 6 by a shaft 10 so as to be able to move up and down on the foot side, and a cylinder 12 is installed between the base 6 and the waist plate 11. The waist plate 11 rotates so that the side moves up and down.

A backrest 14 is supported on the base 6 by a shaft 13 so that the head side of the backrest 14 can be raised and lowered, and the backrest 14 and the base 6 are supported.
A cylinder 15 is installed in between, and the expansion and contraction of the cylinder 15 causes the backrest 14 to rotate with respect to the shaft 13 so as to undulate the head side.

The waist plate 11 side of the backrest 14 is a cavity, and the airbag 16 is accommodated in the cavity, and the backrest 14 is placed from the surface thereof.
The outer cloth 17 is covered with the cloth.

The air bag 16 has the shape shown by the solid line in FIG. 1 when the air pressure is not introduced into the air bag 16, but when the air pressure is introduced into the air bag 16, the air bag 16 inflates to the state shown by the chain line in FIG. Let

A pressure detector 18 for detecting the pressure of the hip bone in the airbag 16 is provided in the pressure adjusting device described later.

FIG. 3 shows a pressure adjusting device for supplying or discharging air to the airbag 16. The pressure from the air pressure source 19 is supplied to the pressure control valve 22 via the check valve 20 and the air filter 21. The output of the pressure control valve 22 is connected to the airbag 16.

A check valve 23 is provided in parallel with the pressure control valve 22,
Backflow of air from the airbag 16 to the air pressure source 19 is prevented.

Further, an electromagnetic valve 24 is provided between the airbag 16 and the pressure control valve 22 and between the atmospheric pressures so that the outputs of the airbag 16 and the pressure control valve 22 can be released to the atmospheric pressure.

The pressure control valve 22 is operated by the pressure detected by the pressure detector 18, and supplies pressure to the airbag 16 so that the pressure applied to the pressure detector 18 becomes constant.

Therefore, when the pressure applied to the airbag 16 by the hipbone of the pregnant woman is small, the pressure detector 18 detects that the pressure is small, and the pressure control valve 22 is operated to operate the pressure detector 18
The pressure is supplied to the airbag 16 until the detection pressure of is constant, and the outer cloth 17 is raised to support the lumbar.

An eccentric wheel 33 is pivotally supported by a shaft 32 on the back surface of the lumbar support 31, and a fulcrum 34 of the eccentric wheel 33 and a fulcrum 35 of the base 6 are connected by a link 36.

Therefore, when the backrest 14 is laid down as shown in FIG. 4, the eccentric wheel 33 is rotated by the link 36, and the eccentric wheel 33 pushes the back surface of the lumbar support 31 to raise it.

In order to deal with this protrusion, the waist plate 11 needs to have the raised portion 37 on the backrest 14 side.

Further, as shown in FIG. 5, when the backrest 14 stands up, the eccentric ring 33 is rotated in the same manner as described above, and the amount of pushing the lumbar support 31 is reduced, so that the protrusion is eliminated.

In this embodiment, the amount of protrusion of the lumbar support 31 can be changed according to the undulating state of the backrest 14.

[Effect of device]

In the present invention, as described above, the lumbar support is raised or not raised when a pregnant woman sits on the waist plate and takes a checkup, a checkup position for delivery, and a delivery position due to a reclining back. Thus, it is possible to relieve pressure on the abdomen and reduce pain caused by pressure on the abdomen.

Further, the pressure applied to the lumbar support is detected, and when the pressure is low, by raising this, the degree of the elevation can be adjusted so that the proper lumbar support is performed.

Therefore, the lumbar support according to this can provide optimal support with minimum abdominal compression.

Furthermore, since the degree of protrusion of the lumbar support can be set in conjunction with the back and forth of the back and forth, the pressure on the abdomen at the time of sitting down, at the examination position or at the delivery position can be reduced, and the pain can be softened. .
