Embodiment 1

[0022] Embodiment 1: as figure 1 with figure 2 As shown, an adjustable chair includes a seat base 1, a seat plate 2 and a back plate 3, a chair foot 4 is installed under the seat base 1, and the seat plate 2 is slidably mounted on the seat base 1. The seat 1 translates along the front-to-back direction, the lower end of the backing plate 3 is hinged on the seat 1, and rotates in the front-back direction relative to the seat 1 , the gap between the backing plate 3 and the seat plate 2 is A linkage assembly 5 is provided, and the seat plate 2 moves when the support plate 3 is rotated and pushed by the linkage assembly 5, and the rotation direction of the support plate 3 is opposite to the translation direction of the seat plate 2, that is, the support plate 3 Rotate backward, seat plate 2 moves forward; Back plate 3 rotates forward, seat plate 2 moves backward.

[0023] The linkage assembly 5 includes a driving member 51 and a driven member 52, one end of the driving member 5...

Embodiment 2

[0026] Embodiment 2: as image 3 with Figure 4 As shown, the difference from Embodiment 1 is that at least one side of the left and right sides of the back plate 3 is provided with a guide seat 11, and the guide seat 11 is fixed on the seat 1, and the arc guide seat 11 There is an arc guide groove 12 with the center of rotation of the backing plate 3 as the center, and the backing plate 3 is fixedly provided with a guide post 31 extending into the arc guide slot 12, and the guide post 31 is When the backing plate 3 rotates, it slides back and forth along the arc guide groove 12 to control the maximum limit position of the front and rear movement of the backing plate 3 . The arc guide groove 12 is provided with a reset assembly that resets the back plate 3, and the reset assembly includes a tension spring 13 and a compression spring 14, and the tension spring 13 is arranged on the front side of the guide post 31. The compression spring 14 is disposed on the rear side of the ...

Embodiment 3

[0028] Embodiment 3: as Figure 5 As shown, the difference from the above embodiment is that a pair of hinged connecting rods 8 are arranged between the seat board 2 and the back board 3, one of which is hinged on the seat board 2, and the other connecting rod 8 is hinged. on the backing plate 3. When the backboard 3 rotates forward to the limit position, the two connecting rods 8 are in a folded state; The hinge point of connecting rod 8, the hinge point of connecting rod 8 and back plate 3 and the projection of the hinge point of said back plate 3 and said seat 1 on the vertical plane are in the same straight line. In this position, the user cannot directly push the seat plate 2 to move backward, and the seat plate 2 can only be moved by turning the back plate 3 forward. When wherein leaning plate 3 rotates backward to limit position, leaning plate and horizontal plane form the included angle of 45 °.

Abstract

The invention relates to the technical field of a chair and especially relates to an adjustable chair. The adjustable chair comprises a chair seat, a seat plate and a back plate, wherein the seat plate is arranged on the chair seat in a sliding form and is capable of moving along the front and rear direction relative to the chair seat; the lower end of the back plate is hinged on the chair seat and is capable of rotating along the front and rear direction relative to the chair seat; a linking component is arranged between the back plate and the seat plate; when the back plate is rotated and ispushed by the linking component, the seat plate is moved; the rotation direction of the back plate is opposite to the translation direction of the seat plate. According to the invention, the front and rear positions of the seat plate are adjusted following the rotation of the back plate, the position of the seat plate is forward moved when the chair user lies backward, the center of gravity of the chair user is forward moved, the chair user is prevented from turning backward and the stability of the chair is promoted.

Description

technical field [0001] The invention relates to the technical field of chairs, in particular to an adjustable chair. Background technique [0002] Chairs are one of the most commonly used furniture in life. In order to make chair users feel more comfortable, the backrests of general chairs are all set to be adjustable. By turning the backrest backwards, the chair has the function of a reclining chair. When the user leans back, the center of gravity also moves backwards, which easily causes the chair to fall backwards. Contents of the invention [0003] The purpose of the present invention is to provide an adjustable chair, which can adjust the position of the seat plate along with the backrest of the chair and improve the stability of the chair. [0004] The above object of the present invention is achieved through the following technical solutions: an adjustable chair, comprising a seat, a seat plate and a back plate, the seat plate is slidably mounted on the seat, and ...
