Abstract

This item is used as a cushion to support and hold the sitting posture or the posture of the back and head of the body. It is composed of oval-shaped bulges on the left and right sides when viewed from the front, a belt part in the center, and two connecting parts connecting the left and right bulges and the belt part. The cover of this cushion is made of fabric such as cloth or waterproof fabric such as synthetic leather that can be wiped with alcohol. In addition, in the left and right bulges, multiple inner covers of different sizes filled with urethane chips are stored inside the cover, and these can be inserted and removed. The material stored in the bulges is not limited to urethane chips, and materials such as urethane and cotton formed into a rod or tube shape can be used. In addition, in the belt part, an inner cover filled with urethane material or urethane chips similar to those in the bulges is stored inside the cover, and it can be inserted and removed from the connecting part depending on the waist width of the user's body, the situation of use, and the purpose. Furthermore, when installing on a chair, bed, etc., the multiple inner covers stored in the bulge can be removed from the bulge to adjust the bulge to large, medium, or small depending on the situation and purpose, such as to match the user's body size, posture, and posture. For people who tend to lean to the right or left side when sitting or on a bed, the left and right bulges can be changed to different sizes to support and maintain their posture. When sitting on a chair with a backrest or a wheelchair, the cushion supports and maintains the sitting posture by placing the center of the cushion's belt part against the back of the person sitting on it, starting from the center of the back of the person sitting on it, and placing the left and right bulges on the sides of the person sitting on it. In addition, when using it on a seat, the left and right bulges of the cushion can be folded, and the center of the belt part can be placed against the center of the person sitting on it's buttocks, and placed on the left and right of the user's ischial bones to reduce the burden on the tailbone, sacrum, and anus. Furthermore, when used as a backrest or headrest during meal assistance in bed, dental or oral care, or grooming and beauty services such as shaving, it can support the back or head and maintain the posture of the upper body.

As shown in Reference Photo 1 showing the state of use, Reference Photo 3 showing the state of use, and Reference Photo 5 showing the state of use, when using this cushion to maintain a sitting posture on a chair with armrests, by arranging the article in the shape of Reference Oblique View 2, the cushioning effect of the urethane material or the like inserted in the belt part gently supports the lower back and maintains the sitting posture. As shown in Reference Photo 2 showing the state of use, Reference Photo 4 showing the state of use, and Reference Photo 6 showing the state of use, by arranging the article in the shape of Reference Oblique View 8, the belt part easily fits against the back of the chair and maintains the sitting posture. As shown in Reference Photo 7 showing the state of use, the article can also be arranged in the shape of Reference Oblique View 9.As shown in Reference Photo 8 showing the usage state, the present article can be arranged in the shape of Reference Oblique View 11. As shown in Reference Photo 9 showing the usage state, the present article can be arranged in the shape of Reference Oblique View 6. The degree of support for the sitting posture can be adjusted by inserting or removing the urethane material or the like inserted in the belt part, or by selecting the shape and size of the bulge part, depending on the width of the waist and the pressure when pinched according to the body shape. The chair to be used is a chair with a backrest, such as a furniture chair, a wheelchair, an office chair, a barber chair, a beauty chair, a hair washing chair, a dental chair, a dialysis chair, a car seat, etc. The cushion has a feature that the belt part is placed on the back when the user is in a sitting posture, and the bulge part is pinched between the armpits and the left and right sides of the waist of the user and the armrests of the chair, thereby obtaining the effect of supporting and supporting the sitting posture. In addition, when using a chair without armrests, the cushion can be easily folded by removing the urethane material or the like stored in the cover of the belt part of the cushion, and when the belt part is placed on the back of the user in a seated position, it covers the lower part of the back and the lower back, and when the user sits down, the belt part of the cushion is sandwiched between the body and the back of the chair to provide support, and the folded bulges on the left and right sides support the left and right lower back and upper part of the lower back of the user, stabilizing the seated position. As shown in Reference Photo 10 and Reference Photo 11, which show the usage state, the product can also be arranged in the shape of Reference Oblique Figure 4. In this way, by placing the product on the seat of a chair with a backrest and armrests, the left and right bulges are bent inward at approximately 90 degrees to the seat and armrests of the chair, supporting the lower back and the area around the greater trochanter, and stabilizing the seated position of the user. As shown in Reference Photo 12, which shows the usage state, the product can also be arranged in the shape of Reference Oblique Figure 6. As shown in Reference Photo 13, which shows the state of use, the present article can also be arranged in the shape of Reference Oblique View 5. By arranging it on the seat of a chair in this way, the left and right bulges are folded into the belt and can be arranged on the left and right of the user's ischial bones, which has the effect of reducing the burden on the tailbone and anus area located in the center of the belt. As shown in Reference Photo 14, which shows the state of use, the present article can also be arranged in the shapes of Reference Oblique View 6 and Reference Oblique View 12.As shown in Reference Photo 15, which shows the state of use, the present article can also be arranged in the shapes of Reference Oblique View 5 and Reference Oblique View 11. In this way, it can be arranged on the seat and back of a chair with a backrest, and by placing the first cushion on the seat of the chair with the left and right bulges folded into the belt, the seat can support the left and right sides of the user's ischial bones, and the effect of reducing the burden on the tailbone and anus area located in the center of the belt can be obtained. By placing the second cushion on the back of the chair, the effect of reducing the burden on the posterior part of the pelvis, such as the tailbone and sacrum, which are located in the center of the belt on the back can be obtained. As shown in Reference Photo 16, which shows the state of use, the present article can also be arranged in the shapes of Reference Oblique View 4 and Reference Oblique View 9. Reference Photo 17, which shows the state of use, shows the state in which a person is sitting in the state of Reference Photo 16. In this way, it can be arranged on the seat and back of a chair with a backrest and armrests. By placing the first cushion on the seat and the second cushion on the back, the back part supports the upper part of the waist from the left and right armpits, and the seat part supports the thighs from the left and right waist, and the effect of stabilizing the sitting posture of people who lean left and right due to weakened trunk and muscle strength is obtained. As shown in Reference Photo 18 showing the usage state, a general back cushion can be placed between the belt part of this product and the back of the user. Also, for people with round shoulders or hunched backs, as shown in Reference Photo 19 showing the usage state, the urethane material stored in the cover of the belt part of this cushion can be removed, and the belt part can be hooked on the back of a chair from the shape of Reference Oblique Figure 7, and one of the bulges can be placed on the upper part of the back of the chair to improve the comfort of the sitting posture. Furthermore, as shown in Reference Photo 20 showing the usage state, by placing one of the bulges on the lower part of the back of the chair so that it touches the lower part to the upper part of the waist as a lumbar support, people with back pain can freely decide the position to maintain a comfortable sitting posture. The chair used for this can be a chair without armrests or an office chair.As shown in Reference Photo 21, which shows the state of use, two of the cushions can be used: the first cushion is in the shape of Reference Oblique View 2, with the center of the user's back as the starting point, the center of the belt is placed against the back, and the left and right bulges are placed under the user's armpits and on the sides of the waist, while the second cushion is in the shape of Reference Oblique View 7, with the urethane material or the like removed from the belt, with the belt hooked on the back of a chair and one bulge placed on the back of the chair and placed from the waist to the back, supporting and maintaining the sitting posture, while also allowing the cushion to be adjusted to a comfortable posture for those with back pain, hunchback, or stooped shoulders. As shown in Reference Photo 22 and Reference Photo 23, which show the state of use, the cushion can be shaped as in Reference Oblique View 3 and placed on a car driver's seat with an armrest on only one side to maintain posture. By placing one of the bulges of this cushion at approximately 90 degrees on the armrest and back of the seat of the driver's seat, placing the connecting part along the back, and folding the other bulge on the belt side and the opposite side of the one bulge, and placing it on the car seat, the driver's lower back is supported by being sandwiched between the left and right bulges, making it easier to maintain a seated posture and reducing lateral shaking while driving. The driver's upper body, such as the armpits and elbows, can move freely without interfering with steering, which also helps prevent lower back pain while driving. The difference in the shape of the reference oblique view 1 or the reference oblique view 7 is whether or not urethane material is inserted into the belt, and the belt can be selected according to preference, such as how it fits the body, and when urethane material is inserted, the cushioning effect gently supports the back of the lower back and reduces the burden. As shown in Reference Photo 24 showing the state of use, Reference Photo 25 showing the state of use, Reference Photo 26 showing the state of use, Reference Photo 27 showing the state of use, and Reference Photo 28 showing the state of use, this cushion can be used when providing assistance with eating in bed, dental care, oral care, grooming services such as shaving, and hair and beauty services.When a bedridden person or a patient who cannot get up receives assistance with eating, dental treatment in bed, oral care, teeth brushing, shaving, or other grooming services, or when receiving haircuts or other beauty services, it is necessary to raise the top of the bed and maintain a sitting posture with the user's back slightly away from the bed, so that the person sitting on the bed can be at the same eye level as the caregiver, dentist, nurse, caregiver, barber, or beautician who is providing the service. In this case, as shown in Reference Photo 24 and Reference Photo 25, which show the usage state, by making the product in the shape of Reference Oblique Figure 7, the cushion can be oriented vertically and one of the bulges can be placed on the head like a pillow, or on the cervical spine or back. Also, as shown in Reference Photo 26, which shows the usage state, by making the product in the shape of Reference Oblique Figure 13, one side can be a rounded large bulge and the other a smaller bulge. The two bulges can be positioned to support the user's cervical spine or head. This allows the user of the cushion to adjust the position and angle of the chin to enjoy a comfortable posture during meal assistance, dental treatment, oral care, tooth brushing, shaving, and other grooming. In addition, the service provider can easily maintain an angle and posture that is easy to provide the service, and the head is stable, leading to safe service provision. In addition, by placing one of the bulges of the cushion on the back as shown in Reference Photo 27 showing the usage state, or by installing the product on the back in the shape of Reference Oblique Figure 6 as shown in Reference Photo 28 showing the usage state, the space between the bed and the head is widened to ensure that the barber or hairdresser can easily cut the back of the head. Furthermore, by installing the product on the back in the shapes of Reference Oblique Figures 5, 11, and 12, the same effect can be obtained by placing the belt on the back with the bulge on top, or by removing the urethane material of the belt. When a barber or hairdresser cuts a bedridden person's hair while they are in bed, it is often the case that two people work together, with one supporting the back and head and the other cutting the hair. It is particularly difficult to ensure safety when cutting the back of the head by one person, but by using this cushion, it is possible for the technician to provide the haircut by himself.By maintaining posture with this cushion placed behind the patient's back, the patient can maintain a sitting position with the upper part of the body raised, and as the patient's line of sight is raised, it becomes easier to assist with eating, provide oral care, brush the teeth, and perform other grooming procedures, which also helps prevent aspiration.
