The health cushion shown in No. 3361 is also the same as a donut-shaped cushion with a hole in the center. The holes shown here have side walls that form holes in the leather of the upper cushion as shown in the figure, and since the shape is different from the lower leather, not only is it troublesome to manufacture, but the leather is Since it is not symmetrical, the side wall deforms when seated, and the hole shape collapses. Further, as another conventional example shown in FIG. 7, the example in which the concave portion 6 is provided in contact with one side of the cushion 5 is as follows.
Since the shape is special, there is a manufacturing problem that the cushion material must be formed in that shape, which is disadvantageous in that it becomes expensive. Moreover, since the concave portion 6 is in contact with one side of the cushion, even if the contact with the ischial bone is blocked, it does not contact the entire circumference of the ischial bone, so that it is easy to fall to the rear side and the sitting posture becomes unstable. There was a serious drawback: The present invention has been made to solve such a problem, and provides a cushion with a hole that allows the user to sit in a stable posture without feeling pain by supporting the buttocks around the entire circumference of the ischium. With the goal.

In order to solve the above problems, the present invention has the following configuration. The cushion with a hole according to claim 1 is provided with a hole by allowing a seat cushion escape hole to be provided in order to shift the disposition position from the center of the cushion having the cushion material and to prevent contact with the seat bone. It was a cushion. Since the buttocks were not pressed by the pointed sit bones and the cushion, the hips did not hurt even when used for a long time. The cushion with a hole according to claim 2 is arranged such that the disposition position is displaced from the center of the cushion having the cushioning material, and a pattern-shaped hole for escape of the ischium is provided to prevent contact with the ischium. , A cushion with holes.
By designing the escape hole as a pattern, not only the fun of the design but also the displacement of the cushion material can be prevented. The cushion with holes according to claim 3 covers a cushioning material provided with holes for escape of the ischium to prevent contact with the ischium, and a marking pattern suggesting the position and shape of the holes. By setting up, it was made into a cushion with a hole. It looks like a standard cushion to another person, and the person can see the escape hole in the position of the pattern. The cushion with a hole according to claim 4 is a cover of the same shape in which two cloths having a cutout of the same shape are provided inside to form an escape hole for preventing abutment with a seat bone. The outer periphery and the periphery of the cutout portion were joined. A cushion with a hole was accommodated in the two-layered cover to form a cushion with holes. Since the upper and lower surfaces of the cover are joined in the same shape, the displacement difference between the upper and lower surfaces due to the pressing force is the same, so that the deformation of the hole during use is small.
