Problems solved by technology

[0006] Furthermore, the common features of the above two types of seats are: the lower part of the seat back needs to be made of more solid material due to the necessity of support, the size is thicker than the upper part, and the shape of the middle and lower part of the seat back is very simple, which is only for the purpose of fixing the connection. Need; the shape of the middle and lower part of the seat back is usually not enough to comfortably support the human waist, so an additional lumbar support is generally installed at the lumbar position of the seat back, which increases the process and cost

Embodiment 1

[0050] Embodiment 1: as Figure 1-4 As shown, the present invention provides a kind of seat, comprising:

[0051] A seat support 1 for supporting a person sitting on the seat, the seat support 1 is a seat support plate of a seat, which is usually a piece of wood or a plate made of plastic material. 1 can be equipped with a cushion made of sponge.

[0052] Rigid back support frame 3, the back support frame 3 exceeds the seat support member 1 upwards, and the shape of the back support frame 3 can be Y-shaped or T-shaped; the lower end of the back support frame 3 is connected with the seat support member 1. A support connecting portion 40 is formed at the upper end of the support frame 3 .

[0053] The back support frame 3 described in this embodiment is a Y-shaped bracket, which includes a main body 41 and fork parts 42 extending obliquely upward from the upper end of the main body 41 toward both sides. The lower end of the main body 41 is bent directly or indirectly. For the...

Embodiment 2

[0063] Embodiment 2: as Figure 5-8 As shown, the difference from Embodiment 1 is that the back support frame 3 in this embodiment is a T-shaped bracket, which includes a main body 41 and bifurcations 46 extending horizontally from the upper end of the main body 41 to the left and right sides. The fork portion 46 has a root end 46a connected to the trunk portion 41 and a free end 46b away from the trunk portion 41. The support connection portion 40 is formed at the free end 46b of the bifurcation portion 46. The frame side 15 also includes a lumbar support The upper support side 47 above the side 17 is higher than the free end 46b of the bifurcation part 46 , and the junction between the upper support side 47 and the lumbar support side 17 is fixedly connected with the support connection part 40 .

Abstract

The invention discloses a seat. The seat comprises: a seat supporting member and a back supporting frame, wherein a supporting connection portion is formed at an upper end of the back supporting frame, the seat further comprises a back supporting member and waist supporting sides, and the waist supporting sides deform under the action of an external force and recover the original shape when the external force disappears. The seat disclosed by the invention is provided with the independent back supporting frame, and the back supporting frame is connected to the middle and upper part of the backsupporting member, which is equivalent to moving the connection position of the back supporting member upward, thereby reducing the stress on the lower part of the back supporting member to a certainextent, a reclining force exerted by a seated person is more transmitted from the back supporting member to the back supporting frame, and the back supporting frame bears more reclining force, whichcan facilitate the thin design of the back supporting member; and when a user leans on the seat, the both sides, that is, the waist supporting sides, at the middle and lower part of the back supporting member twist and approach to each other, resulting in a waist clamping effect to wrap the both sides of the waist of a human body, so that the feeling of leaning is more comfortable.

Description

technical field [0001] The invention relates to the technical field of seats, in particular to a seat. Background technique [0002] At present, there is a seat on the market, which is symmetrically provided with armrests on the left and right sides, and the middle and lower part of the chair back is fixedly connected with the two armrests; Both sides of the lower part are respectively fixedly connected with the rear sides of the two armrests. [0003] The characteristics of the above-mentioned seat are: when the human body is sitting, the back of the human body will first touch the back of the seat in the process of leaning back, so the force of the seat is first on the middle and upper part of the back of the seat, and then through the back of the seat to the upper part of the seat. The pressure from the human body accounts for about half of the pressure on the back of the chair and the armrest. Therefore, the middle and lower part of the chair back connected to the armre...
