Embodiment 1

[0025] Example 1: Reference figure 1 and figure 2 , an ergonomic adjustable structure, which is set in the frame at the two armrests of the seat, and the inner side of the frame is fixed with an inner frame made of a steel pipe through screws. The adjustable structure includes the following components:

[0026] A linkage a, one side of the linkage a is provided with a backrest linkage a-1, and the other side is provided with a seat cushion linkage a-2 opposite to the backrest linkage a-1;

[0027] The two ends of the backrest linkage part a-1 are respectively the fixed end a-1.1 fixedly connected with the backrest 1 and the hinged end a-1.2 hinged with the frame; A chute a-2.1 is provided, and the chute a-2.1 is bent towards the direction opposite to the backrest linkage part a-1, and the slide bar a-2.2 arranged on the seat cushion 2 is slidably connected therein, so The end of the slide bar a-2.2 is provided with a cylindrical chuck a-2.21, and the cross-sectional diamete...

Embodiment 2

[0032] Example 2: Reference figure 1 and figure 2 , an ergonomic adjustable structure, the difference from Example 1 is that: the inner contour of the chute a-2.1 is provided with a lubricating inner sleeve a-2.11, and the lubricating inner sleeve a-2.11 is made of elastic material base layer and a lubricating layer arranged on the elastic material base layer, the slide bar a-2.2 is in contact with the lubricating layer, and when the backrest 1 is pressed down, the slide bar a-2.2 The sliding direction in the chute a-2.1 advances, and the distance between the lubricating layers inside the chute a-2.1 gradually decreases;

[0033] The base layer of elastic material is made of elastic rubber, and the lubricating layer is made of polytetrafluoroethylene.

[0034] The lubricating inner sleeve a-2.11 can lubricate the sliding rod a-2.2 and the chute a-2.1 when they move relative to each other, making the mediation movement smooth and convenient without stagnation; at the same ti...

Abstract

The invention discloses an ergonomically adjustable structure, and belongs to the technical field of adjustable seats, which is arranged in the frame at the armrest of the seats and at least comprisesthe following parts: a linkage part; one side of the linkage part is provided with a backrest linkage part; the other side is provided with a seat cushion linkage part opposite to the backrest linkage part; the seat cushion linkage part is arranged on the seat cushion linkage part of the seat cushion linkage part. A gas spring, wherein one end of the gas spring is hinged to the middle of the linkage and the other end is fixedly connected to the lower part of the frame. As that linkage move relative to the frame with the hinge end as the center, the gas spr is elongated or shortened with the hinge joint with the middle of the linkage as the stress point. The adjustable structure is used on a seat with a backrest, and can be switched between various forms of a sitting posture, a lying posture or even a half lying posture, so that the operation is convenient, and the transmission structure is reasonable and reliable.

Description

technical field [0001] The invention relates to the technical field of adjustable seats, in particular to an ergonomically adjustable structure. Background technique [0002] Seats are tools that are convenient for users to ride. Both chairs and stools can be called seats. In order to make people ride more comfortably, people add backrests to the seats to effectively support the back. [0003] The backrest of the traditional seat usually cannot be adjusted greatly, so it is often impossible to provide an effective and comfortable rest posture when the user needs a lunch break. Now there is a need for an adjustable structure that can make the seat be adjusted to facilitate people to rest in a lying position. Contents of the invention [0004] In view of the above technical problems, the ergonomically adjustable structure of the present invention is used on a seat with a backrest, which can be switched between sitting, lying and even semi-reclining, easy to operate, and the ...
