Detailed ways

The present invention will be further described in detail below with reference to the accompanying drawings.

Example

1 and 2, a comfortable seat includes a seat surface 1, a backrest 2, a fixing member 4, a seat 6 and a connecting member 7; the fixing member 4 is fixed to the lower part of the seat surface 1, and the seat 6 is arranged on the Below the seat surface 1 and fixed with the fixing member 4; the backrest 2 is fixed on the fixing member 4 through the connecting member 7; the connecting member 7 includes a main rod 70 and a support rod 71; One end of the C-shaped part 700 is fixed on the fixing member 4 and the other end is set upward; The opening of the C-shaped part 700 corresponds to the lower side of the rear of the backrest 2; the extension part 701 is inclined as a whole in the direction away from the backrest; the lower end of the support rod 71 is fixed to the upper end of the extension part 701 and the The upper end is connected to the backrest 2 ; the lower portion of the backrest 2 is connected to the C-shaped portion 700 .

When in use, when a person presses the backrest 2 backwards, the C-shaped portion 700 will begin to deform, and its opening will gradually become larger, so that the upper part of the backrest 2 can have a larger range of backward swing, thereby enabling the back of the human body to fully sway. Lean back and relax. Compared with the deformation range of the mesh part, the C-shaped part 700 can give a larger deformation range and better relief effect.

The cross-sectional area of the C-shaped portion 700 is larger than that of the extension portion 701 , and the cross-sectional area of the extension portion 701 gradually decreases from bottom to top.

After this arrangement, on the one hand, the support strength of the C-shaped portion 700 is ensured; on the other hand, the extension portion 701 cooperates with the C-shaped portion 700 to have better deformability, so that the upper part of the backrest 2 is easier to swing backwards.

The backrest 2 includes a connecting rod 20, a rib 21 and a pad 23; there are two connecting rods 20 and are vertically opposite to each other; The pads 23 cover the side of the connecting rod 20 and the rib 21 corresponding to the user; the upper end of the support rod 71 is connected to the upper end of the connecting rod 20 ; the C-shaped part 700 is connected to the lower end of the connecting rod 20 .

After this arrangement, the backrest 2 relies on the deformability of the ribs 21 and the pad 23, so that the back of the human body can be more comfortable and easier to relax when it is in contact with the back.

The connecting rod 20 includes an arc-shaped support part 200 and a deformation part 201; the convex side of the arc-shaped support part 200 faces the user side; the lower end of the deformation part 201 is fixed to the upper end of the arc-shaped support part 200 and transitions smoothly.

After this arrangement, when the back of the human body is leaning on the backrest 2, the arc-shaped support portion 200 cooperates with the ribs 21 and the pads 23 at the corresponding positions to support the waist of the human body, so that the waist of the human body can also be relaxed. more comfortable.

An ear plate 22 is provided at the position of the connecting rod 20 corresponding to the strut 71 and the C-shaped part 700; the lug plate 22 is also provided on the strut 71 and the C-shaped part 700, the connecting rod 20 and the strut 71 and the C-shaped part 700 is hinged through the lugs 22 .

After this arrangement, the backrest 2 and the connecting piece 7 can be deformed more fully, the coordination between the two is better, and the user is more comfortable when using.

There are two supporting rods 71 and they are symmetrically arranged. When in use, the human body leans back, and the backrest 2 presses the connecting member 7; the C-shaped portion 700 is deformed, and the support rod 71 also begins to deform. This can not only make people fully relaxed, but also play a reliable supporting role.

The end face of the upper end of the extension part 701 is provided with an insertion hole, an arc-shaped insertion rod 8 is inserted into the insertion hole, and the headrest 9 is fixedly connected to the end of the arc-shaped insertion rod 8 .

In this way, the waist, back and neck of the human body can be effectively supported during use, and the sitting is more comfortable.

Armrests 3 are arranged on both sides of the seat surface 1, which is convenient for people to support.

A support rod 5 is provided on the seat 6, and the upper end of the support rod 5 is fixed on the fixing member 4. The fixing member 4 can be a fixing block, and the seat is an ordinary seat at this time; the fixing member 4 can also be a hydraulic lifting device , cooperate with the support rod 5 to realize the lifting and lowering of the seat surface 1, and the seat is a liftable seat at this time.

The embodiments of this specific embodiment are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore: all equivalent changes made according to the structure, shape and principle of the present invention shall be covered by the present invention. within the scope of protection of the invention.
