1 to 5, the back cushion according to the present invention includes an upper body 10 and a lower body 20.

The upper body 10 and the lower body 20 are made integrally and are made of an elastic material such as a memory foam or latex that is elastically restored.

First, the upper body 10 supports between the lower and middle parts of the thoracic vertebrae of the body, and is formed to correspond to the curve of the thoracic vertebrae.

That is, the thoracic vertebrae are formed as they enter the front of the body from the middle to the bottom, and the upper body 10 is formed in a curved shape so as to correspond thereto.

At this time, in front of the upper body 10, the thoracic vertebra support portion 11 is formed protruding to contact the thoracic vertebrae to maintain the curve of the thoracic vertebrae.

There are protruding standing muscles on both sides of the thoracic vertebrae, and touching the thoracic vertebrae touches the thoracic spine.

Conventionally, while a groove capable of wrapping up to the standing muscles is formed, the present invention protrudes from the thoracic vertebra support portion 11 that contacts the thoracic vertebra between the standing muscles protruding on both sides of the thoracic vertebrae.

That is, the user can feel the thoracic support portion 11 directly touching the thoracic vertebrae, and as a result, not only can the direction of the vertebrae correspond to the back cushion of the present invention, but also the vertebrae can be felt and maintained by themselves.

The lower body 20 extends from the lower portion of the upper body 10 to the lower portion to support the lumbar body, and is formed to correspond to the curve of the lumbar body.

In addition, the lower body 20, the side of the upper body 10 is extended to the lower portion is formed inwardly curved to the upper side of the back support portion 30 to be described later.

That is, the lumbar spine connects the lower pelvis and the lower part of the thoracic vertebrae, which protrudes to the rear of the body, and the lower body 20 is formed in a 'C' shape to correspond thereto.

At this time, in the front of the lower body 20, the lumbar support portion 21 is formed to protrude the middle portion corresponding to the 'C' shape of the lumbar spine to maintain the curve of the lumbar spine.

The back cushion of the present invention guides the spine through the thoracic support portion 11 and the lumbar support portion 21 to more easily take the 'S' curve posture of the spine.

In addition, both sides around the thoracic support portion 11 of the upper body 10 can be guided to take a 'S' curve posture of the spine as the thickness becomes smaller toward the upper portion.

That is, if the user smacks the spine, the back falls off the chair or wall. At this time, the upper body 10 is inserted into the falling space, and the thickness of the upper body 10 is formed to become smaller toward the upper portion so as to correspond to the space falling from the back, chair or wall. That is, the user's back does not fall from the chair or the wall, but the upper body 10 and the thoracic support 11 are supported on the back, so that the spine can be maintained in a stable and more comfortable state.

In addition, the lower body 20 is formed to be seated on the buttocks and bent into the lower side so as to be supported, but the seating groove 22 is formed by being indented so that the indentation depth becomes larger toward the center of the lower side.

For this reason, when the user inserts and fastens the back cushion of the present invention on the back, the seating groove 22 is seated on the buttocks and is fixed at the inserted position even if the waist is slightly moved, so there is no need to fix and fix the back cushion again. It is very easy to.

On the other hand, the upper body 10, the left and right width between the thoracic support portion 11 and the side is formed with a flexible groove 13 is bent inwardly curved on the side so as to increase toward the upper and lower center of the center.

That is, when the user stretches or bends the waist from side to side, the upper body 10 is bent together in the direction of bending the waist relative to the center, and the flexible groove 13 corresponding to the direction of bending the waist is compressed, The opposite flexible groove 13 is expanded.

And, when the waist, the upper body 10 of the elastic material is restored to its original state.

If the flexible groove 13 is not formed, the user maintains the original state even if the user bends the waist from side to side, and if the user bends and refills, the user must fit the waist back to the cushion. However, the back cushion of the present invention, as the flexible groove 13 is formed, flexes together flexibly in the motion of bending the user's waist, and when the user avoids the bending waist, is restored to the original state, and the user immediately spines To support the upper body 10 and thoracic support portion 11 can take a pin state.

In addition, due to the flexible groove 13, when the upper body 10 is bent, the flexible groove 13 on the opposite side of the bend expands, but the flexible groove 13 formed in a curved shape is stretched in a straight shape and is not torn. Does not.

In addition, the upper body 10, the upper rear side is formed convexly. At this time, the width of the left and right becomes larger toward the upper portion, and the wing portion 14 supporting the back is formed. In addition, while the inner circumferential surface of the flexible groove 13 extends to the rear side surface of the wing portion 14, an elastic groove 15 that elastically supports the wing portion 14 is formed.

That is, the wing portion 14 supports the shoulder moving backward when the shoulder is moved back and forth, and the elastic groove 15 elastically supports the wing portion 14 at the same time.

At this time, the upper rear side of the upper body 10 is convexly formed to be curved, and when the user moves the shoulder back and forth, the upper rear side of the convex upper body 10 can be moved in a smooth contact with the chair back or the wall.

On the other hand, the back cushion of the present invention further includes a back support portion 30 and a side support portion 40.

The back support portion 30, the lower portion is supported on the pelvis, both sides of the lower body 20 is formed to extend outward to support the back between the back ribs and the pelvis.

In addition, the side ridge portion 40 protrudes in front of the back support portion 30 to surround the side, elastically support the side and guide the spine to take a posture.

In addition, the portion connecting the back support portion 30 and the side support portion 40 is curved indentation.

At this time, even if the user corrects by bending the waist to the left or right or moving the posture, the back cushion moves with the user's movement while the seating groove 22 is already seated on the buttocks and the side ribs 40 are wrapped around the side. It is possible to continue to use the back cushion as the first fixed state is maintained without the need to modify the position. In addition, since it is fixed to the user's back as much as possible without means such as a belt, it is convenient to use it without any hassle to fix the back cushion.

That is, as the back cushion of the present invention is flexibly deformed to the user's movement and restored to its original state, it is very easy to use and can promote comfort, as well as to minimize tearing due to deformation. Designed to be curved, it can be used for a long time.

On the other hand, the back of the back support 30 is in close contact with the chair back or the wall surface.

And, the rear of the lower body 20, the lower back recessed groove 23 is formed to be spaced apart from the chair back or the wall surface.

At this time, the lower indentation groove 23 is formed such that the indentation depth increases as it goes from the both sides of the lower body 20 toward the center.

In addition, the rear of the upper body 10, the lower indentation groove 23 is extended to form the upper indentation groove 12.

At this time, the upper indentation groove 12 is formed such that the indentation depth becomes smaller toward the upper portion.

In addition, the side ridge portion 40, when the user closes the back to the upper body 10 and the lower body 20, the upper indentation groove 12 and the lower indentation groove 23 is in close contact with the chair back or wall surface At the same time, it can bend forward and wrap around the sides to support it.
