The present invention relates to a chair, particularly to a waist support chair.
Although the advance in science and technology sets people free from manual labor, people spend more time on electronic products and sit at a desk working for a longer time. People sitting for a long time are likely to adjust the position of the hips to maintain sitting comfortably. In addition, people are likely to sit on the front half to the front two-thirds of the seat. In such a situation, a chair back is unlikely to support the back and the waist. Consequently, more and more people suffer from waist diseases that are unexpected in their ages.
Although many ergonomic office chairs available in the market are claimed to be able to provide support for the back and waist, they cannot contact the S-shaped spine intimately because the waist support structure thereof is not sufficiently convex. Even if able to provide sufficient support for the waist, the waist support structures might be excessively convex and make the user's back contact the chair back intimately.
Accordingly, the present invention proposes a waist support chair, which provides back support and waist support separately, to solve the conventional problems and meet future requirements. The principles and embodiments of the present invention are described in detail below.
The primary objective of the present invention is to provide a waist support chair, which uses an upper support member and a lower support member to respectively support the back and the rear waist of the human body. Each of the upper support member and the lower support member is left-right symmetric, whereby to touch the waist of the human body more intimately and compliantly.
Another objective of the present invention is to provide a waist support chair, wherein a plurality of hollow elastic columns is vertically arranged on the chair bottom to support the hips of the sitter. While the pressure is applied to the hollow elastic columns, the hollow elastic columns are compressed to release air. Thus, the hips of the sitter feels relaxed and comfortable.
In order to achieve the abovementioned objectives, the present invention proposes a waist support chair, which comprises a framework including a back support frame and a chair bottom, which are pivotally coupled to each other; a back support member arranged on the back support frame and adjacent to the chair bottom and including two upper support elements horizontally disposed and left-right symmetric to each other and two lower support elements also horizontally disposed and left-right symmetric to each other, wherein two lower support elements are disposed between two upper support elements and the chair bottom; and a hips support member arranged on the chair bottom and including a plurality of hollow elastic columns, which are compressed to release air while pressurized.
In one embodiment, a back cushion is arranged on one side of the back support frame, and a hips cushion is arranged on one side of the chair bottom.
In one embodiment, two upper support elements are arranged between the back cushion and the back support frame; each upper support element includes an upper connection portion fixed to the back support frame; a plurality of support planes intimately contacting the back cushion to support the back cushion; and a plurality of elastic support bands, wherein one end of each of the elastic support bands is connected with the upper connection portion, and the other end of each of the elastic support bands is connected with a corresponding one of the support planes;
In one embodiment, two lower support elements are arranged between the back cushion and the back support frame, and each of the two upper support elements includes a lower connection portion fixed to the back support frame; a plurality of support planes intimately contacting the back cushion to support the back cushion; and a plurality of elastic support bands, wherein one end of the elastic support band is connected with the lower connection portion, and the other end of the elastic support band is connected with a corresponding one of the support planes; when any one of the support planes is applied with pressure, the support plane is moves backward, and the elastic support band corresponding to the support plane are bent and feeds back a counterforce to the support plane.
In one embodiment, a plurality of slots is used to partition an integral plane into a plurality of support planes, and the quantity of the slots corresponds to the quantity of the support planes.
In one embodiment, the chair bottom includes a plurality of ventilation holes, and the ventilation hole has an opening facing the hips cushion and penetrating the chair bottom.
In one embodiment, the hollow elastic columns are disposed in array and vertical to the chair bottom.
In one embodiment, the hollow elastic columns are in form of hexagonal prisms.
In one embodiment, one end of each hollow elastic column is arranged on the chair bottom, and each hollow elastic column includes an air-release hole traveling through a central axis of the hollow elastic column; and a plurality of air-release branch holes arranged on a surface of one end of the hollow elastic column, which is far away from the chair bottom, interconnecting with the air-release hole, and extended outward with the air-release hole being an axis to form a plurality of air flow channels.
In one embodiment, a gap among four of the hollow elastic columns being neighboring forms an ischium support point.

The hips support member 20 includes a plurality of hollow elastic columns 21. One end of the hollow elastic column 21 is arranged on the chair bottom 18, and the other end of the hollow elastic column 21 contacts the hips cushion 22. The hollow elastic column 21 is made of a memory foam material, used to support the hips of the human body and compressed to release air while pressurized. In one embodiment, the hollow elastic columns 21 are in form of hexagonal prisms, vertical to the chair bottom 18, and arranged in array. Each hollow elastic column 21 includes an air-release hole 212 and a plurality of air-release branch holes 214. The air-release hole 212 travels along the central axis of the hollow elastic column 21 until it contacts the chair bottom 18. The air-release branch holes 214 are arranged on the hollow elastic column 21 and positioned at one end of the hollow elastic column 21, which is far away from the chair bottom 18, i.e., on the surface contacting the hips cushion 22.
The chair bottom 18 further includes a plurality of ventilation holes 24 respectively penetrating the chair bottom 18. The openings of the ventilation holes 24 face the hips cushion 22. The ventilation holes 24 may be used to dissipate heat, whereby the person sitting on the hips cushion 22 feels more comfortable.
In conclusion, the present invention proposes a waist support chair with an upper support element and a lower support element for respectively supporting the back and the rear waist of the human body. The upper support element and the lower support element are in left-right symmetry and can contact the back and waist more intimately and compliantly. Further, the present invention arranges a plurality of vertical hollow elastic columns on the bottom of the chair to support the hips of the sitter.
