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.
Therefore, according to the preferred embodiment of the present invention, when the user is seated on the chair, the thigh rather than the user's hips touches the seat portion of the chair to support the weight of the user, so that the user's hips are not subjected to pressure, It is possible to prevent the sagging of the buttocks and the swelling of the buttocks.
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.
Description
The present invention relates to a chair, and more particularly, to a chair capable of smoothly ventilating and improving a hip sagging phenomenon by forming an opening in a portion where the user touches the buttocks when the user sits.
In general, a chair which is generally used has a designing structure so that the user can sit in a more comfortable and convenient state. In terms of its basic structure, a chair which can be seated, and a backrest portion connected to the rear end of the seat portion, And a stationary supporter fixed to an upper surface of the lower surface of the seat so as to be stably supported on the ground.
In order to provide convenience and comfort to the user in the general configuration of the above-described chair, a head rest which can support the arm rest or the head can be selectively provided on both sides of the seat part. On the other hand, Various kinds of chairs which can be turned back and forth at a certain angle are currently spread to homes, offices, and the like, so that they are selectively used according to the user's preference .
With the spread of automobiles and changes in the way of working, modern people have been sitting on chairs for a long time. The effect of sitting posture on the body is significant, so if you are not in good posture, you will easily feel fatigue and cause pain in your body.
As shown in FIG. 4, Korean Utility Model Registration No. 20-0449832 discloses a seat assembly for a vehicle comprising a
According to the registered utility model, anyone can support the pelvis in accordance with the shape of the bottom of the pelvis in a sitting position, protects the hip joint by gathering legs according to the angle with the femur, By correcting the overall posture from the hip to the vertebrae, it can prevent twisting of the pelvis, dislocation or extension of the hip, and abnormal curvature or stenosis of the vertebrae.
However, since the above-mentioned chair has a structure in which the weight of the upper body is to be supported by all of the hips, problems such as hip sagging, pain and hip area become particularly obtrusive.
In addition, when the user is seated for a long time, there is a problem that ventilation is not performed well and various diseases are caused in the hip area of the user.
SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a seat and a backrest which are provided with openings at respective portions of a user's hips, The purpose of the chair is to provide.
In order to solve the above problems, the present invention provides a chair including a back portion and a seat portion, wherein the back portion includes a back opening formed to open a lower portion of a back portion where a user's hips are located, And a seat opening formed such that a rear portion of the seat portion in which the buttocks of the seat portion is seated is opened, wherein the seat back opening portion and the seat opening portion are formed to be connected to each other.
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.
