1 and 2, the lumbar cushion 100 according to an embodiment of the present invention is positioned between the back of the chair and the back of the user to alleviate spinal disease or back pain when the user is seated on a chair, etc. . The waist cushion 100 includes a body 110 on which the horizontal support portion 120 is formed. The front surface of the body 110 is implemented as a curved surface having a shape in which the horizontal support portion 120 can be formed. A more detailed description of the curved structure of the body 110 of the waist cushion 100 will be described later. The body 110 is implemented as an elastic body having an elastic restoring force, and may be, for example, styrofoam, latex, urethane, rubber, or the like.

Hereinafter, the first stage is referred to as A, the second stage is referred to as A', the direction connecting the first stage (A) and the second stage (A'), that is, the Y direction, is referred to as the vertical direction, and the waist cushion ( The direction orthogonal to the vertical direction of 100) is referred to as the horizontal direction. Accordingly, when the user uses the lumbar cushion 100, the direction of the spine corresponds to the longitudinal direction of the lumbar cushion 100.

The body 110 of the waist cushion 100 according to an embodiment of the present invention is formed with a horizontal support portion 120 in the horizontal direction based on the first point A1. The front of the body 110 has a curved shape that gradually increases in thickness from the first end (A) to the first point (A1), and gradually from the first point (A1) to the second end (A'). It is formed in a thinner curved shape. At this time, from the first end (A) to the first point (A1) is formed as a curved surface of a shape corresponding to the back of the body, and the thickness of the second end (A') is formed thicker than the thickness of the first end (A). . The user may use the first end (A) to be positioned in the thoracic spine direction and the second end (A') to be positioned in the lumbar spine direction.

The horizontal support part 120 is formed by a predetermined area in the horizontal direction based on the first point A1. When the first point (A1) is located at the thoracolumbar junction of the user, the back part of the body is located in a concave curved area formed from the first end (A) to the first point (A1), and the horizontal support part (120) compresses the area extending in the transverse direction from the thoracolumbar junction and the thoracolumbar junction, and supports or distributes the load above the thoracolumbar junction. In this case, the load applied to the thoracolumbar junction is reduced, so that the physiological curvature can be maintained.

Supporting the load above the thoracolumbar junction The human spine is largely composed of 33 vertebrae of the cervical, thoracic, lumbar, sacral and caudal vertebrae from the top, and the thoracic and lumbar junction is the area where the thoracic and lumbar vertebrae are in contact, for example. , T12 of the 12 thoracic vertebrae (T1 to T12) and the area where L1 of the 5 lumbar vertebrae (L1 to L5) is located (T12 to L1), or the thoracic vertebrae T11 and T12, and the lumbar vertebrae L1 and L2 Sites (T11 to L2) may be indicated.

As described above, the human spine is formed in the shape of a physiological curvature, and when a deformation such as a retraction of the thoracolumbar junction region to the back occurs, pain or the like occurs. At this time, the weight on the upper part of the thoracolumbar junction may exacerbate these symptoms. The lumbar cushion 100 according to an embodiment of the present invention has a horizontal support part 120 formed in a transverse direction with respect to the user's thoracolumbar junction region, and supports the physiological load above the user's thoracolumbar junction region, and the degree of curvature By compensating for the deformation to maintain the physiological curvature, it is possible to alleviate the user's spinal disease or back pain.

1 and 2 illustrate an example in which the horizontal support 120 is provided integrally with the body 110, but is not limited thereto, and the horizontal support 120 is a separate material or a structure that is detachable to the body 110 It can also be implemented. The same is true for the following other examples.

The waist cushion 100 according to an embodiment of the present invention may further include a ribcage support 140. The ribcage support 140 is integrally connected to the side surface of the body 110 and is implemented in a curved shape surrounding the ribcage corresponding to the thoracolumbar junction. According to the example of FIG. 1, the thoracic support 140 protrudes in the positive direction of X from the first end A, protrudes most before reaching the horizontal support 120, and then retreats in the negative direction of X. It is implemented in a curved shape that reaches the second stage (A').

As such, the lumbar cushion 100 according to an embodiment of the present invention wraps the ribcage located at both ends in the transverse direction to the thoracolumbar junction of the user to support and distribute the weight above the thoracolumbar junction. ), it is possible to more efficiently alleviate the user's spinal disease or back pain.

In the waist cushion 100 according to an embodiment of the present invention, further, at least one or more grooves 160 may be further formed on the front surface of the body 110 in the horizontal direction. When the user uses the lumbar cushion 100, the groove 160 increases the frictional force between the user and the lumbar cushion 100 to fix the position of the lumbar cushion 100 for convenience of use and the upper part of the thoracolumbar junction. It can increase the effect of supporting and dispersing weight.

3 is a view showing a waist cushion according to another embodiment of the present invention, and FIGS. 4 and 5 are cross-sectional views of the waist cushion of FIG. 3 in directions A-A' and B-B', respectively.

3 to 5, the waist cushion 100 of FIG. 3 is a curved surface that gradually increases in thickness from the first end (A) to the first point (A1), similar to the waist cushion 100 of FIG. 1 The body 110 has a shape and is formed in a curved shape gradually thinning from the first point (A1) to the second end (A'), and the body 110 has a horizontal shape based on the first point (A1). A certain area in the direction is formed by the horizontal support part 120. The cross section in the direction B-B' of FIG. 3 may be the same as that of FIG. 5, and it can be seen that the thickness of the horizontal support part 120 is the thickest based on the rear surface 130.

In addition, the waist cushion 100 of FIG. 3 is also integrally connected to the side surface of the body 110 and is implemented in a curved shape surrounding the rib cage corresponding to the thoracolumbar junction. At least one or more grooves 160 may be further formed on the surface in the horizontal direction.

However, while the body 110 of the waist cushion 100 of FIG. 3 is larger than the waist cushion 100 of FIG. 1 and the thickness at the first end (A) and the second end (A') is the same or similar, the body Based on the first point (A1) of (110), the length (D1) from the first end (A) to the first point (A1) and the length from the first point (A1) to the second end (A') The length D2 is provided in a different asymmetric shape. For example, an example is shown where the length D1 from the first end A to the first point A1 is longer than the length D2 from the first point A1 to the second end A'. have.

The user's back is positioned so that the body 110 of the waist cushion 100 is positioned between the first end (A) to the first point (A1) and between the first point (A1) to the second end (A'). Along with the formation of a curved surface corresponding to the back of the body, the length between the first end (A) and the first point (A1) and between the first point (A1) and the second end (A') is asymmetrical shape. By being provided, the first end (A) may be positioned upward (in the direction of the thoracic vertebrae of the spine) or the second end (A') may be positioned upward according to the user's body shape. For example, as shown in FIG. 4, the length D1 from the first end (A) to the first point (A1) is between the first point (A1) and the second end (A'). If it is longer than the length (D2), a person with a larger body shape can use the first stage (A) to be positioned in the thoracic spine direction and the second stage (A') to be positioned in the lumbar spine direction, and those with a small body shape can use the second stage ( It can be used so that A') is located in the direction of the thoracic spine and the first end (A) is located in the direction of the lumbar spine.

As such, the lumbar cushion 100 according to the embodiment of the present invention is formed in an asymmetric structure in the vertical direction of the lumbar cushion, so that even if it is used in a vertical direction according to the body shape, it accurately performs support in the transverse direction for the thoracolumbar junction As a result, the same shape of the waist cushion can be used by all users of different body types, thereby reducing the cost required for product production and management, thereby increasing price competitiveness.

Furthermore, the lumbar cushion 100 of FIG. 3 includes a first thoracic support part 140_1 and a second end (A') in which the thoracic support part 140 is located between the first end (A) and the first point (A1). It may be provided as two of the second thoracic support portions 140_2 positioned between the first points A1. In this case, even if the upper and lower positions of the waist cushion 100 are changed according to the user's body shape, support for the user's rib cage may be performed.

6 and 7 are views together to show the effect of the waist cushion according to an embodiment of the present invention.

6 is an X-ray picture when a user places the lumbar cushion 100 according to an embodiment of the present invention between the back of the chair and his or her back. In the case of the X-ray picture, the chair and the lumbar cushion 100 ) Was added to the shape of the lumbar cushion 100 because it was not taken, and in reality the lumbar cushion 100 may have been pressed by the pressure of the human body, but it is still shown in a circular shape to aid understanding. In the case of FIG. 6, the physiological curvature of the spine is maintained by distributing the load by the body weight above the thoracolumbar junction where the transverse support 120 is located at the thoracolumbar junction (T12-L1). In the case of FIG. 7 in which the lumbar cushion 100 is not used according to, it can be seen that the curvature of the spine is deformed to form an almost straight line. When the curvature of the spine is deformed as shown in FIG. 7, the load will be concentrated to the lumbar region and pain will be accompanied.

8 and 9 are views each showing a waist cushion according to another embodiment of the present invention.

First, referring to FIG. 8, the waist cushion 100 is formed in contact with the rear surface of the body 110, has an area equal to or smaller than the rear surface of the body 110, and is made of a material lower than the elastic modulus of the body 110. It may further include (180). At this time, it should be noted that the modulus of elasticity is related to the degree of deformation. For example, the rear support plate 180 is a metal having a lower elastic modulus than the body 110 made of a material having elastic resilience, such as styrofoam, latex, urethane, and rubber, that is, a relatively low degree of deformation due to external pressure. Or it may be implemented with plastic or the like.

Further, a plurality of support protrusions 182 having a constant height may be formed on the first surface of the rear support plate 180, that is, the first surface of the rear support plate 180 in contact with the rear surface of the body 110. In this case, the support protrusion 182 may be provided by being compressed on the body 110 or inserted into the body 110. FIG. 8 shows an example in which most of the support protrusions 182 have the same height, and the support protrusion 182 of the horizontal support part 120 is formed higher than the other support protrusions 182. However, the present invention is not limited thereto, and the support protrusion 182 may be provided in various forms. For example, since the height of the plurality of support protrusions 182 is formed in proportion to the thickness of the body 110, the plurality of support protrusions 182 may be provided in a step shape as a whole.

As such, the waist cushion 100 according to the embodiment of the present invention may further improve the support force of the horizontal support portion 120 by further including the rear support plate 180 or the support protrusion 182. FIG. 8 illustrates a case in which the rear support plate 180 to the support protrusion 182 are additionally provided in the lumbar cushion 100 according to the embodiment of FIG. 3, but is not limited thereto, and the lumbar cushion 100 of FIG. 1 Applicable to

Next, referring to FIG. 9, the waist cushion 100 according to the embodiment of the present invention is located in the vertical direction at the center of the rear surface 130 of the body 110, and is provided with a material lower than the elastic modulus of the body 110. It may further include a vertical support (190). Depending on the user's body shape, the use of the lumbar cushion 100 may not be smooth by the thoracic support 140. For example, when the user's back is larger than the width of the waist cushion 100, that is, the length of B-B', it is not possible to efficiently support the thoracolumbar junction by the horizontal support unit 120. At this time, the vertical support unit 190 controls the angle of the chest support unit 140 by limiting the deformation caused by the lumbar cushion 100 to a certain degree even if the user with a large body shape uses the lumbar cushion 100, so that the horizontal support unit ( 120) can perform efficient support for the thoracolumbar junction.

The present invention is not limited to the embodiments disclosed below, but may be implemented in a variety of different forms. The present embodiments are provided only to make the disclosure of the present invention complete, and to fully inform the scope of the invention to those skilled in the art to which the present invention pertains, and the present invention is defined by the scope of the claims.
