Description

[Technical field]

[0001] The present invention relates to a cushion for use while sitting. [Background technology]

[0002] Various cushions aimed at women after giving birth have been proposed (for example, Patent Document 1). Patent Document 1 discloses a donut-shaped nursing cushion that is worn around the waist when nursing and has an opening on the back side. This nursing cushion can reduce the burden on the nursing woman while keeping the baby in a stable position during nursing. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6061168 Summary of the Invention [Problem to be solved by the invention]

[0004] By the way, it is generally said that women often experience physical discomfort, especially pain, during pregnancy and the postpartum period (the period until the changes in the mother's body caused by pregnancy and childbirth return to their pre-pregnancy state). One of the causes is a well-known fact in the fields of physical therapy and obstetrics and gynecology that is said to be "posterior pelvic tilt."

[0005] Retroverted pelvic tilt refers to a state in which the pelvis is tilted backward. Normally, the natural posture of the pelvis is a slight forward tilt, but retroverted pelvic tilt is the opposite, that is, tilted backward, and is said to have a negative effect on the posture of the entire body. One of the factors that causes this retroverted pelvic tilt is said to be the breastfeeding posture. However, since the conventional technology including Patent Document 1 is a cushion that is worn around the waist and is intended to stabilize the posture of the infant, a cushion that can alleviate physical discomfort on the part of women during pregnancy and the postpartum period, including the viewpoint of the breastfeeding posture, has been desired.

[0006] Therefore, an object of the present invention is to provide a cushion that can relieve the physical discomfort of the user. [Means for solving the problem]

[0007] The cushion of the present disclosure comprises: It is shaped like an arc when viewed from above. A cushion body having a seat surface for a user to sit on; Two belt members to which auxiliary cushions are attached; Equipped with When the two belt members are wound around the cushion body with the center line of the cushion body as an axis of symmetry, the two auxiliary cushions are attached to the cushion body in an "inverted V-shape" in which the distance between the two auxiliary cushions narrows toward the front of the seated user in a plan view. . Effect of the Invention

[0008] According to the present invention, the physical discomfort of the user can be alleviated. [Brief description of the drawings]

[0009] [Figure 1] 1A is a perspective view of a cushion according to an embodiment of the present invention, and FIG. [Diagram 2] FIG. 2 is an exploded perspective view of the cushion according to the embodiment of the present invention. [Diagram 3] 1A and 1B are diagrams illustrating a state in which a cushion is used according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] The cushion in this embodiment will be described with reference to Figures 1 and 2. The cushion 1 includes a cushion body 2, two auxiliary cushions 3A and 3B, and two belt members 4A and 4B to which the two auxiliary cushions 3A and 3B are attached, respectively.

[0011] The cushion body 2 has a predetermined thickness (symbol s1 in FIG. 2), and is filled with natural materials such as cotton, synthetic resins such as polyurethane, elastic materials such as rubber, etc. The upper surface 20 of the cushion body 2 serves as the seating surface when a user P (FIG. 3) sits on it. Considering that the main users P of the cushion 1 are postpartum women, it is desirable to use a highly resilient urethane foam with strong resilience so that the cushion body 2 does not sink too much when seated.

[0012] The thickness s1 (Fig. 2) of the cushion body 2 is preferably about 7 cm. The reason is that breastfeeding is done in various places such as on the floor, on a chair, on a sofa, or in bed. In particular, breastfeeding is often done on the floor for about three months after childbirth, during which time women tend to develop physical disorders due to the weakening of their trunk muscles after childbirth. When breastfeeding on the floor, the mother often takes the "cross-legged position" shown in Fig. 3. However, if the mother takes the "cross-legged position" on a flat floor, the position of the sitting bones is lower than the position of the knees, so the hip joints bend deeply, the pelvis tilts backward (backward tilt), and the waist curves. This causes the spine to curve and the head to assume a forward head position (head is forward of the shoulders), which leads to physical disorders.

[0013] Therefore, by setting the thickness s1 of the cushion body 2 to about 7 cm, the height difference between the knees and ischium is almost eliminated when the user P is seated, and the hip joint is prevented from bending deeply, allowing the pelvis to be raised vertically and maintain a posture. As the pelvis is raised, the ischium bears the load (bone support), which is expected to facilitate the activity of the pelvic floor muscles and abdominal muscles.

[0014] The cushion body 2 may have a structure in which materials of different hardness are laminated in the vertical direction. For example, when the cushion body 2 has a three-layer structure, a soft sponge having a lower hardness than the upper and lower layers is sandwiched between them as an intermediate layer, which is expected to make it easier for the user P to move his / her center of gravity.

[0015] As shown in FIG. 1(b), the cushion body 2 is formed in an "arc" shape with a part of the circumference cut off in a plan view. More specifically, the cushion body 2 includes a bent portion 2A that is gently bent in a plan view, and a first extension portion 2B and a second extension portion 2C that extend continuously from both ends of the bent portion 2A. The bent portion 2A supports the buttocks of the user P, the first extension portion 2B supports the left thigh of the user P, and the second extension portion 2C supports the right thigh of the user P (FIG. 3). When the user P is seated, the cushion body 2 has a recess 5 that is concave in plan view on the front side of the user P. By having the recess 5, even if the user P takes a "cross-legged posture", both feet are located within the recess 5 and do not interfere with the cushion 1.

[0016] Next, the auxiliary cushions 3A and 3B will be described. In Figures 1 and 2, the auxiliary cushions 3A and 3B extend in one direction and have a predetermined thickness s2 (Figure 2). The material filled inside the auxiliary cushions 3A and 3B can be the same as that of the cushion body 2, but it is preferable that the material has a lower hardness than the cushion body 2, i.e., is softer than the cushion body 2.

[0017] 1(b), the length dimension t of the auxiliary cushions 3A, 3B in the longitudinal direction is set to be substantially the same as the length dimension in the width direction (direction along the length dimension t) of the cushion main body 2, or at least equal to or less than the length dimension t. In other words, the auxiliary cushions 3A, 3B are sized to fit on the upper surface 20 of the cushion main body 2 in a plan view. Note that the length dimension t of the auxiliary cushions 3A, 3B may be greater than the length dimension in the width direction of the cushion main body 2.

[0018] The thickness s2 of the auxiliary cushions 3A, 3B is set to be thinner than the thickness s1 of the cushion body 2. Although the thickness s2 of the auxiliary cushions 3A, 3B is preferably 1 / 3 or less of the thickness s1 of the cushion body 2, the thickness does not necessarily have to be set in this manner. In this way, the auxiliary cushions 3A, 3B are lower in hardness and thinner than the cushion body 2.

[0019] The belt members 4A, 4B are used to fix the auxiliary cushions 3A, 3B to the cushion main body 2. In Fig. 2, a hook-and-loop fastener (male) 6 is provided as an engagement means at one end of the front surface of the belt members 4A, 4B, and a hook-and-loop fastener (female) 7 is provided as an engagement means at the other end of the back surface. The auxiliary cushions 3A, 3B are attached to the belt members 4A, 4B at approximately the center thereof by sewing or the like.

[0020] The auxiliary cushions 3A and 3B are fixed to the upper surface 20 of the cushion main body 2 by wrapping the belts 4a and 4B around the width direction of the cushion main body 2 (arrow a shown in Figure 1(b)) and engaging the hook-and-loop fastener (male) 6 with the hook-and-loop fastener (female) 7 (Figure 1).

[0021] As described above, the cushion body 2 is formed in an "arc" shape in plan view. Therefore, when the auxiliary cushions 3A and 3B are attached symmetrically to the cushion body 2 with the center line C (FIG. 1(b)) of the cushion body 2 as the axis, the auxiliary cushions 3A and 3B are arranged in an "inverted V" shape, with the distance between them narrowing toward the front of the seated user P. In other words, the auxiliary cushions 3A and 3B are arranged at positions corresponding to the two ischial bones (ischial tuberosities) located below the buttocks, which are part of the user P's pelvis.

[0022] Since the position of the ischial bones differs depending on the individual user P, the auxiliary cushions 3A, 3B can be attached to the cushion body 2 at any position via the belt members 4A, 4B to align the auxiliary cushions 3A, 3B with the ischial bones. The belt members 4A, 4B also function as adjustment means for adjusting the fixed positions of the auxiliary cushions 3A, 3B with respect to the cushion body 2.

[0023] As described above, the cushion 1 in this embodiment includes the cushion main body 2 having a seating surface on which the user P sits, and two auxiliary cushions 3A, 3B that are detachable from the cushion main body 2. The two auxiliary cushions 3A, 3B are attached to the seating surface of the cushion main body 2 so that, in a plan view, the distance between the two auxiliary cushions 3A, 3B narrows toward the front of the seated user P, forming an "inverted V-shape." The two auxiliary cushions 3A, 3B attached to the cushion main body 2 are located at positions that correspond to the ischial bones of the user P when he is seated.

[0024] In this way, by attaching (fixing) the auxiliary cushions 3A, 3B to the positions corresponding to the ischial bones of the user P in a seated position, the auxiliary cushions 3A, 3B provide sensory stimulation to the ischial bones, making it easier to support the ischial bones, and the burden on the lower back can be expected to be reduced. In addition, by supporting the ischial bones with the auxiliary cushions 3A, 3B, it is expected that the sensory input will be provided to activate the muscles around the pelvis. In general, it is possible to suppress posterior pelvic tilt and alleviate physical discomfort of the female user P, especially during pregnancy and the postpartum period.

[0025] The cushion of the present invention is not limited to this embodiment, and the design can be appropriately modified within the scope of the invention. For example, a structure in which a recess is provided on the upper surface of the cushion body and an auxiliary cushion is fitted into this recess may be used. However, since the position of the ischial bone varies from person to person, a structure in which the position at which the auxiliary cushion is fixed to the cushion body can be adjusted, as in this embodiment, is preferable. Also, a buckle may be used instead of a hook-and-loop fastener as an engagement means. Furthermore, the cushion may be used not only by ordinary women, but also by men. [Industrial Applicability]
