2, a joint 115 for connecting the two support members 114 and 116 is disposed at a portion where the third cutout portions 26 are formed. By operation of the cylinder 120, the joint 115 ) Portion is moved upward, the vicinity of the left third incision portion 26 is convexly deformed.

At this time, a portion of the lower body 20 of the portion where the left third slit 26 and the fourth slit 27 are formed is in a compressed state. Therefore, the third slit 26 and the fourth slit 27, The lower portion of the first cutout portion 27 is formed into a trapezoidal sectional shape so that the portions of the third cutout portion 26 and the fourth cutout portion 27 can be broken so that the left cylinder 120 is operated upward The lower body 20 can be prevented from being wrinkled.

The end of the right cylinder 122 is also coupled to the lower portion of the right third incision 28 through the joint 123. When the end of the right cylinder 122 is driven upward, The portion of the right side third cutout 28 and the portion of the fourth cutout 29 are formed in a circular and trapezoidal cross-sectional shape, Thereby preventing the body 20 from being wrinkled.

And an intermediate connection layer 30 formed of a synthetic resin material and disposed between the upper body 10 and the lower body 20 and coupling the upper body 10 and the lower body 20 together .

The intermediate connection layer 30 may also be formed of, for example, foamed polyurethane, and the intermediate connection layer 30 is formed in a harder state than the upper body 10.

Thus, the body is smoothly supported through the upper body 10, and the upper body 10 and the lower body 20 are coupled while the intermediate connection layer 30 firmly supports the body.

That is, the upper body 10, which is in direct contact with the body, is formed in a softer state to smoothly support the body, and the intermediate connection layer 30 is formed as a hard layer to maintain the shape of the entire metris And is configured to firmly support the body.

The intermediate connection layer 30 is formed in a substantially vertically symmetrical shape with respect to a center line extending along the horizontal direction and coupling portions for coupling the upper body 10 and the lower body 20 are formed.

As described above, the intermediate connection layer 30 is vertically symmetrically formed with respect to the center line of the horizontal direction, thereby providing substantially the same bonding force to the upper body 10 and the lower body 20.

At both ends of the intermediate connection layer 30 are formed both end connection portions 32 for coupling the upper body 10 and the lower body 20 and at the center of the intermediate connection layer 30, (38) is formed.

The engaging protrusions 32-1 and 32-2 are formed symmetrically in the vertical direction on the both end engaging portions 32. The engaging protrusions 32-1 and 32-2 are formed on the upper body 10 and the lower body 10, The upper body 10 and the lower body 20 can be coupled to each other through the intermediate connection layer 30. [

4, spinal support portions 34, 36-1 having a substantially triangular cross section and a rectangular cross-sectional concavo-convex shape are formed between the both-end coupling portion 32 and the center coupling portion 38 on the right side.

The triangular cross section and the rectangular cross section refer to a side cross-sectional shape protruding upward or downward with respect to a horizontal center line crossing the center portion of the intermediate connection layer 30.

The spinal support portion 34 in the form of a triangular cross-sectional concavo-convex shape is formed so as to support the cervical spine and the shoulder periphery from the back of the person, and the spinal support 36-1 in the form of a square cross-sectional concave-

The upper body 10 and the lower body 20 are coupled to each other through the upper and lower portions of the lumbar support portion 36-1 so that the lumbar support portion 36-1 of the rectangular cross- To some extent.
