Abstract

The present invention provides a cushion capable of distributing pressure applied to the back over the whole. A cushion cover 1 is provided with vertically long bag-like portions 2 to 6, and each bag-like portion is partitioned by sewing. Insert the stick balloon into the bag-like parts 2-6. Further, the amount of air injected into the stick balloon is adjusted so as to match the shape of the user's back and inserted into the bag-like portions 2 to 6 respectively. For example, the air pressure of the stick balloon inserted into the bag-like portions 2 and 6 is relatively 10, the air pressure of the stick balloon inserted into the bag-like portions 3 and 5 is 8, and the air pressure of the stick balloon inserted into the bag-like portion 4 is 6. Then, in the case of a standard person, the correct posture is maintained along the shape of the back. [Selection] Figure 1

Description

The present invention relates to a backrest cushion that is used for the backrest of a wheelchair table chair, etc., and prevents or reduces pressure sore back pain by holding the back of the user.

If a person with a physical disability or a deformed spine sits in a wheelchair or chair for a long time, the contact point between the backrest and the back concentrates on one point, which can cause pressure ulcers and pain.

Conventionally, bead cushions, cushions, and air cushions are used between the back and backrest.

Because the bead cushion is not fixed in shape, the beads gather at the bottom, making it difficult to match the shape of the user's back, and when the cushion is dripping, the pressure concentrates on one point and may cause pain . There is an air cushion, but there is no thickness, the air pressure is constant and the pressure applied to the back is little dispersed, and it is difficult to reduce pressure sore back pain.

Thus, conventional cushions are not made according to the user's waist, back shape, and intended use.
An object of this invention is to provide the cushion which can disperse | distribute the pressure concerning a back to the whole.

The present invention solves the above-mentioned problem, and is sewn so as to provide an existing stick balloon storage chamber in a longitudinal bag shape with a breathable and stretchable fabric, and the stick balloon is inserted into this storage chamber. It is a back cushion characterized by things.

Since the present invention can be expanded and contracted by adjusting the internal air pressure of each stick balloon, it can be inflated to a desired hardness so as to fit the shape of the user's waist and back.

The stick balloon is divided into multiple pieces in the vertical direction, so that the back is wrapped and supported from both sides to support and disperse body pressure.

Moreover, since the groove is formed in the vertical direction, the air permeability is good, and even if it is drowned for a long time, it can be used comfortably without causing stuffiness.

Since the air of the stick balloon can be easily removed, the main body can be folded small when not in use, and can be easily stored and carried.

In addition, since the existing stick balloon can be used and the cushion cover can be manufactured by means such as sewing, the equipment can be simplified, so that the manufacturing cost can be reduced and the back cushion can be provided at a low cost.

The backrest cushion according to the first embodiment of the present invention will be described with reference to FIG. 1. 1 is a cushion cover, and vertically long bag-like portions 2, 3, 4, 5, and 6 are provided. It is partitioned by sewing. 7 is a lid, and Velcro tapes 8, 10, and 12 (registered trademarks are also registered) are attached to the lid portion 7 at three locations, while Velcro 9 is also attached to the surface of the bag-like portions 2, 4, and 6. , 11, 13 are attached. When the lid is closed, the magic tapes 8 and 9, 10 and 11, and 12 and 13 are coupled to close the lid 7.

In FIG. 2, reference numeral 14 denotes a stick balloon for insertion into the bag-like portions 2, 3, 4, 5 and 6.

The amount of air injected into the stick balloon 14 is adjusted so as to match the shape of the user's back and inserted into the bag-like portions 2 to 6 respectively.

FIG. 3 shows a state where the lid is closed after the stick balloons 14 are inserted into the bag-like parts 2 to 6, respectively.
(Example of use)

For example, the air pressure of the stick balloon inserted into the bag-like parts 2 and 6 is relatively 10, the air pressure of the stick balloon inserted into the bag-like parts 3 and 5 is 8, the air pressure of the stick balloon inserted into the bag-like part 4 is 6 Then, in the case of a standard person, the correct posture is maintained along the shape of the back.
