感を与えることがないようにしている。When the undulating posture of the back floor is further changed from the set posture to the undulating side, the projecting surface of the projecting member is such that the waist floor upper end corner of the back floor and the back floor upper end angle of the waist floor. It is configured so as to be located at a position projecting to the side of the placed object placed on the floor portion rather than a straight line connecting the section. Therefore, when the angle of the undulating posture of the back floor is smaller than the angle in the set posture, the interior angle between the waist floor side end of the back floor and the back floor side end of the waist floor is large, so When it is judged that the radius of curvature of the bent portion of the mattress, which is the object placed in the gap between the lumbar floor and the floor, is large and the unnecessary protrusion of the projecting member is suppressed, and the angle of the undulating posture of the back floor is the set posture. If the angle is larger than the angle of, the inner angle between the waist floor side edge of the back floor and the back floor side edge of the waist floor is small, so the curvature of the bent portion of the mattress located in the gap between the back floor and the waist floor is small. It is judged that the radius is small, and the protruding member is projected toward the mattress side. This makes it possible to increase the radius of curvature of the bent portion of the comforter, and to make the bent portion of the comforter gentle and to match the bent portion of the comforter to the body line as much as possible, not only to the lumbar spine and abdomen but also to the diaphragm. I try not to give a feeling of pressure.
