Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 This invention belongs to the cushions used on chairs, car seats. It belongs to the cushion applied to the physically and physically weak, especially those with weak legs. After a sick person or an old person sits down on a chair or a seat of a car, his / her legs are weak when he / she stands up. In the case of automobile seats, the height of the seat is low and the hip side is inclined downwards.In addition, the space inside the room is narrow, and there is an assistance to assist with standing up such as handrails. Since there are no tools, it becomes more difficult to stand up.

[0002]

[Prior art]

 The inventor is unaware of this type of conventional example. What the inventor knows is that the stability of the lower back is achieved only by bending the seat futon at best, and therefore the difficulty in standing up cannot be solved.

[0003]

[Problems to be solved by the device]

 The problem to be solved by this invention is that the sick person and the old person often have difficulty in standing up because they have weak legs when standing up after sitting on a chair or a car seat, so it is easy and reliable. It is to provide cushions with auxiliary functions that allow them to stand up.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the cushion with the first auxiliary function is equipped with an expandable air bag in a closed state equipped with an air valve on one side of the cushion body, and in a normal state, the cushion is extended horizontally. It is characterized in that the cushion main body positioned is provided so as to incline from the upper back side to the lower front side by the inflation of the air bag.

A cushion having a second auxiliary function is characterized in that, in the first invention, an air pump is connected to the air valve.

In the cushion having the third auxiliary function, in the first or second invention, the inclination angle of the cushion main body when the air bag is inflated is about 30 to 75 degrees. It is characterized by.

[0007]

[Action and effect]

 In the normal state, the air bag attached to the cushion body is compressed and flattened, and then the cushion body side is placed on the upper side and the compressed air bag is placed on the lower side and placed on the seat of the car, etc. Place the buttocks on the side. In this state, the cushion according to the present invention can be used without feeling uncomfortable as in a widely used cushion. When the seated person stands up, the air bag is inflated by supplying air to the air bag.

[0008] Thus, the air bag is gradually inflated, so that the cushion main body arranged in the horizontal direction follows the inflation of the air bag with the lower front side as a reference, and the back side gradually rises. Since the back side is displaced upward, the cushion body is tilted within a certain range, which has the effect of gradually lifting the buttocks. Thus, a person who has had difficulty standing up can forcibly get up because the cushion body is forcibly lifted.

[0009]

[Embodiment of device]

 An embodiment of the invention will be described with reference to FIGS. 1 to 4. FIG. 1 is a side view showing the normal state of the cushion of the present invention, which is compressed flat. FIG. 2 is a side view of the cushion of the present invention when in use, showing a state where the air bag is inflated and the cushion body is tilted. FIG. 3 is a side view showing a normal state in which a person uses a cushion on a seat. FIG. 4 is a side view showing a state in which a person uses this cushion to stand up from the seat.

The cushion 10 according to the present invention includes a cushion body 12, an air bag 14, an air valve 16, and the like. The cushion main body 12 is generally made of foamed plastics, as known, since it has advantages such as low cost and light weight, but of course, the material is not limited. As long as it functions as a cushion, cotton or synthetic fiber can be applied. However, with this device, it is planned to be carried by people, so the inventor adopted urethane resin as the material in order to reduce the weight. Therefore, it is appropriate that the cushion body 12 has a thickness of about 30 to 50 mm. When the foamed plastics are used as the material, air does not pass for closed cells, but air passes for open cells. It is recommended to attach a non-breathable sheet to maintain Thus, when air is supplied into the air bag 14 attached to one side of the cushion body 12, the air does not leak to the outside through the continuous bubbles of the cushion body 12.

A closed air bag 14 is attached to one side of the cushion body 12. The air bag 14 is also planned to be filled with gas in addition to air, but a flexible plastic sheet that can expand and contract is suitable if it is made of a material that does not leak air, but there is no limitation. The air bag 14 is configured such that the cushion body 12 which is normally positioned in the horizontal direction expands when air is supplied to the air bag 14, so that the cushion body 12 inclines from the upper rear surface to the lower front surface. Has been done.

Furthermore, the cushion body 12 is provided so that the back side thereof is lifted upward with reference to the front lower side thereof. Therefore, the back side of the air bag 14 is provided in a bellows shape that can expand and contract. By providing the back side of the air bag 14 with a stretchable bellows shape, the back side is stretched when air is supplied. Therefore, by keeping the height of the bellows-like portion on the back side constant, the extension amount is increased. It can be controlled and as a result the tilt angle of the cushion body 12 can be set.

The means for setting the inclination angle of the cushion main body 12 to a constant value is not limited to providing the back side of the air bag 14 in a stretchable and bellows-like manner, but when the flat air bag 14 is inflated. Further, as shown in the drawing, the air bag 14 may be formed of a stretchable sheet material so that the air bag 14 is set to have a triangular shape even if it has a maximum cross section.

An air valve 16 is provided in the air bag 14 in order to control supply and discharge of air and gas to the air bag 14. An air inlet is provided in series with the air valve 14, and an air pump 18 can be connected if necessary.

Since the present invention has the above-mentioned configuration, it has the following advantages. When used in a chair or car seat, it can be used as a general cushion comfortably by making it flat without supplying air to the air bag. On the other hand, when a seated person stands up, air is supplied to the air bag to inflate the air bag. As a result, the cushion body rises on the back side with respect to the lower front, so the cushion body moves from the upper back to the front. Since it is inclined toward the bottom, the person's buttocks are forcibly lifted. Therefore, even a person with weak legs can stand up without difficulty. In addition, since the volume of the cushion according to the present invention can be reduced by compressing it, it can be carried and used. In addition, when it is put under the waist at bedtime and a small amount of air is put into the air bag, it also functions as a medical aid to prevent so-called bed sores of the sick person.
