Description

  The present invention relates to a cushion that reduces a burden on a body when sitting or the like.

  If you sit on a chair for a long time, your buttocks and back will hurt. Therefore, in order to reduce the burden on the body, many chairs that incorporate cushions on the seat are used. Moreover, a cushion different from the chair may be laid on the chair according to preference. For example, Patent Document 1 describes a cushion for holding a sitting posture, which includes an anchor material and a cushioning material that is integrated and positioned thereon. In this cushion, the thickness of the anchor material located below the sciatica is thinner than the thickness of the anchor material located below the thigh, and an opening is formed in the portion of the anchor material located below the sciatic bone. One or two concave grooves for holding the thigh are formed in a portion located below the part.

  However, the cushion described in Patent Document 1 only supports the thigh and the buttocks, and the back is not taken into consideration, so the burden on the upper body cannot be reduced.

  The present invention has been made based on such a problem, and an object thereof is to provide a cushion that supports at least a part of the back and can further reduce the burden on the body.

  The first cushion of the present invention includes a support that supports at least a part of the back from at least a part of the thigh through the pelvis, and the support includes at least one part of the back from at least a part of the thigh. The support is formed with two concave grooves corresponding to the thigh and extending so as to sandwich the spine therebetween, at least on the thigh. It is formed from a part to at least a part of the back.

  The second cushion of the present invention includes a support body that supports at least a part of the back, and the support body is formed by extending two concave grooves so as to sandwich the spine therebetween.

  According to the first and second cushions of the present invention, since the two concave grooves are formed on the support so as to sandwich the spine therebetween, the convex stripes between the two concave grooves It can support the spine (spine) and spine standing muscles. Therefore, body pressure can be dispersed by protecting the spinal column and spinal column standing muscle thickly, and the burden on the body can be reduced.

  Further, according to the first cushion of the present invention, since the support body is continuously formed from at least a part of the thigh to at least a part of the back, the gap between the chair and the buttocks is reduced. It can support the pelvis, relax the gluteal muscles, and expand the range of motion of the hip joint. Further, since the support is formed with two concave grooves extending from at least a part of the thigh to at least a part of the back corresponding to the thigh, the two concave grooves The thigh can be supported along the rear thigh, and the adduction and abduction of the hip joint can be suppressed. In addition, since the coccyx and the lower part of the sacrum can be supported by the two concave grooves, it is possible to stabilize the sitting position. Furthermore, since the buttocks and the thigh rear are supported by the two concave grooves, the supported area can be widened to disperse the body pressure, and the burden on the body can be reduced.

The cushion 1 is used, for example, by being placed on the surface of a chair M, and includes a support 10 that supports at least a part of the back from at least a part of a human thigh via a pelvis. .

  The support 10 is continuously formed so as to correspond from at least a part of the thigh to at least a part of the back. The support body 10 has, for example, a rectangular shape, and has two concave grooves 11 formed on the surface so as to extend from at least a part of the thigh to at least a part of the back. The two concave grooves 11 correspond to the thighs on the thigh side, and are formed to extend so as to sandwich the spine therebetween on the back side.

  The length L1 of the support 10 is preferably 70 cm or more and 140 cm or less, for example. Whether the length L1 of the support 10 supports at least a part of the thigh to a part of the back, supports at least a part of the thigh to the entire back, that is, supports the shoulder, It is selected depending on whether to support from at least a part of the thigh to the head. The width W1 of the support 10 is preferably 30 cm or more and 60 cm or less, and more preferably 35 cm or more and 50 cm or less. If it is too narrow, the body cannot be supported sufficiently, and if it is too wide, handling becomes inconvenient. The thickness T of the support 10 is preferably, for example, 2 cm or more and 8 cm or less, and more preferably 3 cm or more and 7 cm or less. If it is too thin, the effect of reducing the burden on the body is small, and if it is too thick, handling becomes inconvenient.

  The width W2 of the two concave grooves 11 formed on the surface of the support 10 is preferably 6 cm to 14 cm, more preferably 7 cm to 13 cm, and more preferably 8 cm to 12 cm. preferable. The interval between the two concave grooves 11, that is, the width W3 of the convex portion 12 between the two concave grooves is preferably 6 cm or more and 14 cm or less, 7 cm or more and 13 cm or less, and more preferably 8 cm or more and 12 cm or less. If it is in, it is more preferable. Within these ranges, the two concave grooves 11 can correspond to the thighs and buttocks, and the convex ridges 12 between the two concave grooves 11 correspond to the spinal column (spine) and the spine standing muscle. Because you can.

  The two concave grooves 11 may be provided on the whole along the length direction of the support 10, or may be provided on a part thereof. The length L2 of the two concave grooves 11 is preferably 70 cm or more and 140 cm or less, and more preferably 70 cm or more and 100 cm or less. This is because it is provided from the thigh to the part corresponding to the spine. The depth H of the two concave grooves 11 is preferably 1 cm or more and 5 cm or less, and more preferably 1.5 cm or more and 4 cm or less. This is because a high effect can be obtained within these ranges.

  The shape of the concave groove 11 in the direction perpendicular to the length direction may be, for example, a quadrangle, but is an arc, a shape obtained by rounding two corners on the lower side of the quadrangle, or a flat part at the bottom. And the shape which tied the plane part and the upper end part with the circular arc is preferable. This is because it can be naturally fitted to the thigh and buttocks.

  Further, the support 10 preferably includes, for example, a buffer portion 13 provided with two concave grooves 11 on the surface and a base material portion 14 provided on the back side of the buffer portion 13. It is preferable that they are formed by joining them. It is preferable that the buffer part 13 is comprised by foaming urethane, latex, or a gel, for example. The latex may be natural rubber latex or synthetic rubber latex. The thickness of the buffer portion 13 is preferably, for example, 1.5 cm or more and 7.5 cm or less, and more preferably 2.5 cm or more and 6.5 cm or less.

  The base material part 14 is a basis for supporting the buffer part 13, and is preferably made of a material harder than the buffer part 13. Examples of the material constituting the base material part 14 include synthetic latex. The thickness of the base material portion 14 is preferably, for example, 0.5 cm or more and 2.5 cm or less, and more preferably 0.5 cm or more and 2 cm or less.

  For example, as shown in FIG. 4, the cushion 1 is used by being disposed along the seating surface M1 and the back surface M2 of the chair M. A person sitting on the chair M from above the cushion 1 is supported by the cushion 1 from at least part of the thigh to at least part of the back via the pelvis. At that time, the thigh and the buttocks are supported by the two concave grooves 11, and the spinal column and the spinal column standing muscle are supported by the convex ridges 12 between the two concave grooves 11.

  In FIG. 4, the surface on which the two concave grooves 11 are formed, for example, the side of the buffer portion 13 is the side in contact with the person, and the opposite surface, for example, the base portion 14 side is the chair M. Although the case where the cushion 1 is disposed is shown as the contact side, the surface on which the two concave grooves 11 are formed may be disposed on the side in contact with the chair M, and the opposite surface may be disposed on the side in contact with the person. If the surface on which the two concave grooves 11 are formed is the side in contact with a person, the two concave grooves 11 and the convex ridges 12 between them act directly on the thigh and the spinal column, If the surface on which the concave groove 11 is formed is the side in contact with the chair M, the cavity of the concave groove 11 is crushed by a person sitting and acts indirectly on the thigh and spinal column. Can be used properly.

  As described above, according to the present embodiment, since the two concave grooves 11 are formed in the support 10 so as to sandwich the spine therebetween, the convex stripe portions 12 between the two concave grooves 11 are formed. Can support the spinal column and the spinal column standing muscle. Therefore, body pressure can be dispersed by protecting the spinal column and spinal column standing muscle thickly, and the burden on the body can be reduced. Further, since the support body 10 is continuously formed from at least a part of the thigh to at least a part of the back, the pelvis can be supported with a small gap between the chair M and the buttocks, It can loosen the fissure and widen the range of motion of the hip joint.

  Further, since the support 10 is formed with two concave grooves 11 extending from at least a part of the thigh to at least a part of the back corresponding to the thigh, the two concaves are formed. The thigh can be supported along the rear thigh by the groove 11, and the adduction and abduction of the hip joint can be suppressed. In addition, since the coccyx and the lower part of the sacrum can be supported by the two concave grooves 11, the sitting position can be stabilized. Furthermore, since the buttocks and the thigh rear part are supported by the two concave grooves 11, the supported area can be widened and the body pressure can be dispersed, and the burden on the body can be reduced.
