Further, in the present invention, the backrest part further comprises a backrest opening cover formed to protrude from the back of the backrest at a predetermined distance from the backrest opening at a position corresponding to the position where the backrest opening is formed.

Further, in the present invention, the seat portion may further include a seat opening cover protruding from a bottom surface of the seat portion so as to be spaced apart from the seat opening portion at a position corresponding to a position where the seat opening portion is formed.

Further, in the present invention, the backrest and the seat portion are each formed in a plurality, and the backrest openings of the adjacent backrest portions are communicated with each other, and the seat openings of the adjacent seat portions are communicated with each other.

In addition, in the present invention, the backrest is formed with a protrusion at a position corresponding to a portion where the user's waist is positioned along the front surface of the front, and the protrusion is formed as a vertex at the top of the backrest and the top And a waist support portion formed to be inclined toward the waist support portion.

Further, in the present invention, the ratio of the length of the seat opening to the length of the seat portion is 1: 0.23 to 0.82.

According to a preferred embodiment of the present invention, when the user sits on a chair, the thigh rather than the user's hips contacts the seat of the chair to support the weight of the user, so that the user's hips are not subjected to pressure, There is an effect that it is possible to prevent sagging phenomenon and fatigue on the hip region.

Further, according to the preferred embodiment of the present invention, since the hip region does not touch the chair by the backrest opening portion and the seat opening portion, ventilation is smoothly performed, so that various diseases and pain related to the hips can be prevented.

2 is a perspective view of a chair according to a second preferred embodiment of the present invention.
3 is a perspective view of a chair according to a third preferred embodiment of the present invention.
4 is a view showing a chair of Korean Registered Utility Model No. 20-0449832.

Hereinafter, a chair according to a preferred embodiment of the present invention will be described with reference to the drawings.

However, the embodiments of the present invention may be modified into various other forms, and the scope of the present invention is not limited to the embodiments described below.

Furthermore, embodiments of the present invention are provided to more fully explain the present invention to those skilled in the art. Accordingly, the shapes and sizes of the elements in the drawings may be exaggerated for clarity of description, and the elements denoted by the same reference numerals in the drawings are the same elements.

1, which is a perspective view of a chair according to a first preferred embodiment of the present invention, the chair comprises a backrest part 100 and a seat part 200, And a backrest opening 110 formed to open the lower portion of the backrest 100 where the buttocks of the backrest 100 are located.

The present invention also includes a seat opening 210 formed in the seat portion 200 such that a rear portion of the seat portion 200 where the user's hip is seated is opened.

In a preferred embodiment of the present invention, the backrest opening 110 and the seat opening 210 are formed to be connected to each other.

That is, the connecting portion where the backrest portion 100 and the seat portion 200 are orthogonal to each other is opened.

On the other hand, in the preferred embodiment of the present invention, the ratio of the length of the seat opening to the length of the seat portion is, for a general adult chair having a seat portion length of approximately 40 cm, The length from the back of the adult male to the hip bone is approximately 8.5 cm and the thickness of the subcutaneous fat of the buttocks is approximately 2 cm. Therefore, when the allowance from the rear end of the seat portion is taken into consideration, The ratio can be 1: 0.31.

However, when the user is taller and fat than the above-mentioned standard, the length of the seat opening is increased when the seat is slightly obliquely seated, and the ratio of the length of the seat portion to the length of the seat opening portion may be 1: 0.82.

In addition, when the user is small in height and lean when the user is sitting on the seat, the length of the opening portion may be reduced, and the ratio of the length of the seat portion to the length of the seat opening portion may be 1: 0.23.

Therefore, it is preferable that the ratio of the length of the opening portion to the seat portion according to the preferred embodiment of the present invention, that is, the length of the seat portion: the length of the opening portion = 1: 0.23 to 0.82.
