Abstract

The invention relates to a chair. The chair comprises a cushion, a tilting adjustment mechanism and a pedal, wherein a slide rail is arranged below the cushion, the slide rail stretches and slides relative to the cushion, the pedal is rotatably arranged at the outer end of the slide rail, the tilting adjustment mechanism comprises a base, a spring, a spring front engine base, and a resisting block, the resisting block is arranged in the base, and the lower end of the resisting block stretches out of the base. When the slide rail shrinks and the pedal returns beneath the base, the pedal extrudes the resisting block upward so as to drive the resisting block to rise, the rising resisting block blocks the sliding of the spring front engine base, so that the tilting angle adjustment range of the tilting adjustment mechanism is reduced. The chair has a simple and reasonable structure design, the pedal can be completely put below the base, when the chair is used as a chair, the tilting anglechanges in a small scope, so that the chair is convenient to sit by people and working is facilitated; and when the chair is used as a bed, the pedal stretches out, the tilting angle changes in a large scope, so that the chair is convenient for people to rest.

Description

technical field [0001] The present invention relates to a chair. Background technique [0002] There is a chair with an adjustable inclination angle, and the adjustment of the inclination angle is all realized by a manual handle. When the chair is in the seat state, adjust the manual handle so that the back of the chair can be tilted within a certain range; when the chair is in the lying state, adjust the manual handle, and the back of the chair can be tilted in a larger range. The tilting function can only be adjusted manually, which is inconvenient to use. Contents of the invention [0003] Therefore, the object of the present invention is to provide a chair that can adjust the reclining angle of the chair through the contraction or extension of the footrest. [0004] The purpose of the present invention is achieved like this. [0005] A chair comprises a seat cushion, a reclining adjustment mechanism, and a footrest. A slide rail is arranged under the seat cushion, a...
