Description

Seat structure improvement

This creation is an improved seat structure that allows the back of the chair to cover the back of the user, to adjust the sitting position, support the waist, and reduce the pressure on the back of the waist.

In the seat of the plastic material of Zhizhi, the bearing part is mainly divided into a separate type of the chair panel and the seat back panel, or the seat panel and the seat back panel are integrally formed. The above structure has the following disadvantages: (1) The seat panel and the seat back panel are separated, and the back of the chair supports the weight of the back seat of the user, and an additional metal support frame is required, which is complicated to assemble and high in cost. (2) The seat panel and the back panel are integrally formed to support the back weight of the user's back chair, and the back panel of the chair needs to be made rigid and less comfortable when leaning. (3) The backrest of the chair has at most only a fixed and undeformable curved surface, so as to fit the back of the user. The back of the chair cannot be deformed according to the shape of the user or the seat, and cannot effectively support the waist.

The present invention is to improve the above-mentioned shortcomings. The main technology and purpose are: a bearing seat and a chair frame, and the seat frame is locked under the bearing seat. The bearing seat structure comprises: a chair panel integrally formed and a seat back panel; the seat back panel has a convex curved surface; the seat back panel is provided with a plurality of longitudinal slots, wherein the seat back panel has a plurality of supporting sheets; The plurality of longitudinal grooves are provided with reinforcing ribs to strengthen the strength of the support piece. When the back of the user leans against the back panel of the chair, the plurality of support pieces can be deformed according to the shape of the user, covering the back of the user, and the effect of adjusting the sitting posture, supporting the waist, and relieving the waist pressure can be achieved.

Please refer to the first, second and third figures, which are a carrier 20 and a chair frame 10, and the frame 10 is locked under the carrier 20. The structure of the bearing base 20 includes: a chair panel 21 integrally formed and a seat back panel 22; the seat back panel 22 has a curved surface of the convex portion 220 and is provided with a plurality of longitudinal grooves 23, so that the seat back panel 22 has a plurality of energy The elastically deformable support piece 24; the plurality of longitudinal grooves 23 are provided with reinforcing ribs 230. Wherein the back of the seat back panel 22 and the seat panel 21 is connected, a venting opening 25 is provided to increase the air permeability, and a plurality of supporting ribs 26 are provided to strengthen the supporting force of the seat back panel 22.

Please refer to the fourth figure, which is a schematic cross-sectional view of the back panel of the present invention. The thickness of the plurality of support sheets 24 is different. The thinner the support sheet 24 is, the closer it is to the center of the back panel 22, the greater the degree of elastic deformation.

According to the above structure, the following effects and advantages can be obtained: (1) By providing the reinforcing ribs 230 in the plurality of longitudinal grooves 23, the strength of the support piece 24 is reinforced, and the endurance strength is increased. (2) The back panel of the chair has a curved surface of the convex portion 220, so that the back panel 22 can fit the curve of the back of the human body without additional purchase of the backrest. (3) Please refer to the fifth figure again, which is a schematic cross-sectional view of the chair back plate, wherein the thickness of the plurality of support pieces 24 is different, and the thinner the support piece 24 is, the closer the thickness is, the more the elastic deformation is. Big. When the back of the user leans against the back panel 22, the plurality of support sheets 24 will deform along with the shape of different users, covering the back of the user to achieve the effect of supporting the waist and reducing the pressure on the back of the waist. (4) Please refer to the sixth figure, which is a schematic diagram of the creation. When the user sits on the carrier 20 and the back is close to the seat back panel 22, the seat back panel 22 can be tilted slightly backward, and the user chair is initially tilted. By comfort. Wherein, the plurality of supporting ribs 26 structure reinforces the supporting force of the bearing seat 20 to be inclined backward, so that the integrally formed bearing seat 20 can bear a larger weight of the seat. (5) Since the carrier 20 is integrally formed, a plurality of longitudinal grooves 23 can be provided to form a structure capable of covering the back of the user. Therefore, the processing and assembly are simple, and the production cost can be greatly reduced.

In summary, the present invention utilizes the plurality of elastic support piece structures to enable the back of the chair to cover the back of the user, thereby achieving the effects of adjusting the sitting posture, supporting the waist, and relieving the waist pressure, and has excellent practical effects, and is in line with the new patent. The keynote, please give a patent.
