DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cushion for a wheelchair used by an elderly or handicapped person with a physical disability, or a hospitalized patient in a hospital to sit and move.

[0002]

2. Description of the Related Art Conventional commercially available wheelchairs have a simple and versatile structure having a seat and a back seat which are slightly wider than the occupant's body. For this reason, when a disabled elderly person, a handicapped person, or a hospitalized patient moves while sitting in an existing wheelchair, his or her limb is disturbed, causing the seated posture to be distorted and slipping out of the wheelchair, or for a long period of time. Being bedridden for a long time made it difficult for them to sit upright because their ability to support their body was weakened, and it was painful and difficult to maintain their posture for a long time even if they were seated correctly. On the other hand, if you are bedridden for a long period of time, you will have bedsores and will not be able to move around, causing stress both physically and mentally, and there will be no recovery of physical strength. So, even if you can sit in a wheelchair for a short time without pain, you can have a good time both physically and mentally, and with this accumulation, the seating time of the wheelchair gradually increases and you get used to the wheelchair life. Will come. As a countermeasure for this, pads have been developed which are inserted into necessary places such as the waist side and the thigh side when seated in a wheelchair. However, this pad is attached to a suitable place with a so-called flat fastener (trade name: Velcro). However, since the pressure exerted by the body is applied unexpectedly, the pad loses the engaging force of the fastener and the pad moves to support the body. There was a problem that it shifted. Also, in order to prevent the body of the seated person from slipping, cover the front side of the upper body from the seat seat, hang the upper part around the shoulder with a shoulder belt, pass through the back of the backrest, and hang the seat seat from the lower side of the wheelchair to the back side. Safety belts have been developed that engage the belt and hold the body. However, in this case, since a shoulder belt is wrapped around the shoulder of a seated person with a physical disability, the seated person who cannot sit in a normal posture places a burden on the contrary. In addition, since it only supports the body with a belt, it has a strong sense of restraint, so that long-term use puts a burden.

[0003]

The problem to be solved by the present invention is to solve the above-mentioned problems and to provide a good sitting posture due to abnormal muscle tone such as the elderly or the disabled or the limited range of motion of joints. For people who are difficult to keep and sit in a wheelchair, insert the appropriate amount of cushioning material according to the individual and adjust the bulging shape of the bulging pad to help the occupant maintain the posture,
An object of the present invention is to provide an auxiliary cushion for a wheelchair that provides a comfortable sitting posture that is comfortable and free from a restraint.

[0004]

According to a first aspect of the present invention, a square backrest and a square seat are provided with a cushion having a thin and uniform thickness inside each of them. Composed of soft cloth stuffed with wood,
At the corner of the backrest, there is a knot for locking to the wheelchair frame, reaching from the rear part of the seating part to the vicinity of the front end of the seating part, the rear part has the width of the seating part and becomes narrower as it becomes the tip. Attach the trunk support cloth to the back of the seating part to support the buttocks of the seated person, which is made of soft cloth with a knot at the tip, and to prevent slipping. The abutment with the waist, the abutment with the outside of the thigh of the occupant on both the left and right sides of the seat, and the abutment with the inside of the thigh of the occupant on the center front side of the seat. It is an auxiliary cushion for a wheelchair, provided with a pad.

According to the second aspect of the present invention, the swelling pad comprises an elliptical bag having a zipper at the entrance, on the front side of a cloth bag packed with a cushion material having a thin uniform thickness and constituting a backrest portion and a seating portion. 2. An auxiliary cushion for a wheelchair according to claim 1, wherein the zipper is closed by arranging an oval bag with a cushion material of an amount adjusted according to the body shape of the seated person so as to be freely refillable from the entrance and closing the fastener. It is.

According to a third aspect of the present invention, there is provided the wheelchair auxiliary cushion according to the second aspect of the present invention, wherein the cushion material of the bulging pad is a cotton-like body.

The operation of the wheelchair auxiliary cushion according to the present invention will be described. First, the function of the swelling pads provided in each abutting part will be described. The swelling pads abutting the sides and the waist of the occupant on the left and right sides of the backrest part help the lateral stability of the trunk which is easily collapsed. It helps to maintain trunk stability and maintain a comfortable posture. The bulging pads that contact the outside of the thigh and the back of the buttocks of the occupant on both the left and right sides of the seating part can support the pelvis, which is the most important in maintaining posture, and support the pelvis from the peripheral side The voluntary body movement of the seated person itself is also possible, and it functions to maintain trunk stability and disperse body pressure to maintain a comfortable posture. In addition, the bulging pad on the thigh inside contact portion of the seated person on the center front side of the seating portion acts to prevent the lower body, especially the buttocks, from sliding forward and stabilizes the sitting position, and as a result, on a wide seating surface Since weight can be supported, the occurrence of pressure sores can be reduced and prevented.

Each of these bulging pads is formed of a pocket-shaped bag, and the bag has an entrance, and the entrance can be opened and closed with a zipper, so that the amount of cotton such as polyester is determined according to the user's body type. Since the bag can be packed in the bag, it is easy to adjust the amount of the seat to keep the sitting posture without burdening the user. Therefore, the posture can be easily corrected gradually while changing the packing amount. Since the swelling pad is packed with a flocculent body, the density and hardness at an arbitrary position in the bag can be easily changed, so that the swelling pad can be adjusted to the user's condition at will. Furthermore, if a cotton-like body such as polyester cotton is used as a cushion material to be packed in the bulging pad,
The floc absorbs perspired sweat, is non-slippery, and can withstand light washing and is hygienic.

Further, the trunk supporting cloth for supporting the buttocks and the crotch of the seated person is placed on the trunk supporting cloth, so that the trunk supporting cloth protrudes from below the buttocks and lowers between the crotch. It is folded back on the abdomen to hold the lower body, and the tying strap attached to the front end is tied to the frame of the wheelchair on the side, so that the body does not slip down. Since the rear portion of the trunk support cloth has the width of the seating portion, it is held so as to wrap around the buttocks, and becomes narrower toward the tip, so that it does not become an obstacle between the crotch.
