Reference numeral 1 is a seat cushion with a backrest portion of the first embodiment, which is formed in a rectangular shape by a synthetic resin material having flexibility and waterproofness, and has a bag shape as a whole. It is formed on the main body 2.
A liquid substance 8 or a gel-like fluid substance 8 having a good thermal conductivity is hermetically contained in the bag-shaped main body 2, and a bent portion 3 is provided at an intermediate portion of the bag-shaped main body so that it can be freely bent. A seat portion 4 is provided on one side of the bent portion 3 and a backrest portion 5 is provided on the other side thereof. A flat heating element 9 is arranged on the inner bottom surface of a seat portion 4 provided on one side of the bag-shaped main body 2, and an outlet 10 for connecting to an external power source is attached to one side of the flat heating element 9.

An opening 6 is provided at the center of the surface of the backrest 5 provided on the other side of the bag-shaped body 2, and the peripheral edge of the pressing portion 7 formed to be expandable and contractible is integrally attached to the opening. Since the pressing portion 7 is formed slightly weaker than the pressure resistance of the material of the bag-shaped main body 2,
When the internal pressure of the fluid substance 8 increases, the fluid substance 8 bulges forward from the opening 6 provided at the center of the surface of the back support portion of the bag-shaped main body. 11 is a mounting band attached to the back surface of the backrest portion 5 of the bag-shaped main body 2, and is a chair 35
Alternatively, the seat cushion 1 with a backrest placed on the seat is attached so as not to move or drop.

Next, a seat cushion with a backrest portion 21 of the second embodiment shown in FIG.
The outer bag formed of a flexible synthetic resin material and the inner bag 27 formed of a waterproof and stretchable rubber material, a flexible synthetic resin material, or the like are entirely formed into a double bag shape. The body 22 is formed. Inside the bag-shaped main body 22, a fluid substance 8 in the form of a liquid or a gel having good thermal conductivity is hermetically accommodated, and a bent portion 23 is provided at an intermediate portion of the bag-shaped main body. A seat portion 24 is provided on one side and a backrest portion 25 is provided on the other side. A flat heating element 9 is arranged on the inner bottom surface of a seat portion 24 provided on one side of the bag-shaped main body 22, and an outlet 10 for connecting to an external power source is provided on one side of the flat heating element 9.

The inner bag 27 located in the opening 26 provided at the center of the surface of the backrest 25 can bulge outward when the pressure of the fluid object 8 increases to form a pressing portion 27a. Reference numeral 11 denotes a mounting band attached to the back surface of the backrest 25 of the bag-shaped main body 22 so that the seat cushion 1 with the backrest positioned on the chair 35 or the seat does not move or fall.

Next, the operation of this embodiment will be described. First, the first
To use the seat cushion with backrest 1 according to the embodiment, a mounting band 11 attached to the backrest 5 of the bag-shaped main body 2 in which the bent portion 3 is bent according to the angle of the chair 35 or the chair. To the chair 35 or chair. Next, as shown in FIG. 3, when the user sits on the seat portion 4 of the bag-shaped main body 2, weight is added to the fluid substance 8 in the bag-shaped main body 2 to move in the bag-shaped main body 2 in the direction of the arrow in FIG. Will be even. However, since the pressing portion 7 attached to the opening 6 of the backrest portion 5 is formed to be slightly weaker than the material of the bag-shaped main body 2 and has elasticity as a whole, the pressing portion 7 is removed by the pressure applied to the fluid object 8. It bulges in the direction and pushes the back of the person sitting on the seat pad 1 with the backrest by the pressing portion 7 to extend the curled bad posture as shown in FIG. It is intended to prevent backache by reducing the accumulation of fatigue.

Moreover, when sitting on the seat portion 4 of the seat cushion 1 with the backrest portion, the fluid object 8
Can be made to flow in conformity with the shape of the buttocks by the seated person, and can sit on the seat section 4 without any discomfort. Also, the fluid object 8 is caused to flow by the weight of the seated person and the pressing section 7 that swells up his back. By pressing and stretching the rounded back muscles, the user can sit in the correct posture, and fatigue can be prevented even if the vehicle is continuously driven for a long time. Also, the back pressing portion 7
By pressing with, the acupressure effect can be applied to prevent recurrence of low back pain or relieve pain.

By energizing the flat heating element 9 on cold winter days,
When the fluid material 8 contained in the bag-shaped body 2 is heated, the fluid material convects in the bag-shaped body 2 and does not convey a cooling sensation to the seat portion 4 and the backrest portion 5 and can warm the hips and waist. The lower back can be prevented from cooling and blood circulation can be promoted. The outlet 10 connected to the flat heating element 9 can be used depending on the place where a normal household power source, battery power source, or the like is used.

When the bag-shaped body 22 of the second embodiment is used, the seat cushion 21 with the backrest portion is positioned on the chair 35, fixed by the mounting band 11, and then seated in the seat 24 and placed in the bag-shaped body 22. When weight is added, the fluid substance 8 in the bag-shaped main body 22 has a uniform pressure inside the inner bag 27. However, since the material of the inner bag 27 is formed to be slightly weaker than the pressure resistance of the outer bag 22, the back of the inner bag 27 is pressed by the pressing portion 27a that bulges forward from the opening 26 by the pressure of the fluid substance 8 to be rounded. It is possible to correct bad posture and prevent the accumulation of fatigue.

The pressing portions 7 and 27a that bulge from the openings 6 and 26 of the bag-shaped main bodies 2 and 22 contract due to the stretching force of the bag-shaped main bodies 2 and 22 when the weight applied to the seats 2 and 24 is removed. The swelling of the pressing portion 7 and the inner bag 27 is canceled and the original state is returned to a flat state.

"Effect of the device" The present invention, while sitting on the seat part of the seat hood with a backrest part, uses its weight to move the fluid in the bag-shaped main body to project the pressing part provided on the back part part to the outside. As a result, a bad posture with a curled back is straightened out and straightened, thereby preventing the burden on the lumbar region, so that the occurrence or recurrence of low back pain due to accumulated fatigue can be prevented. Further, the planar heating element may be heated to heat the fluid substance in the bag-shaped body to prevent the bottom of the body from being cooled and warmed to promote blood circulation and prevent accumulation of fatigue. Further, the seat band can be attached to a chair or the like with a mounting band attached to the back part to prevent the seat pad from slipping or falling.
