Leisure sofa chair

Abstract

The invention discloses a leisure sofa chair which comprises a chair surface, a chair back, a chair foot, a pedal, a chair back support rack, an active driving mechanism, a gravity center moving mechanism and a pedal adjusting mechanism, wherein the chair back is connected with the chair surface; the chair foot is fixed at the bottom of the chair surface; the pedal is connected with the chair surface; the support rack is connected with the chair back; the active driving mechanism is connected with the chair back support rack; the gravity center moving mechanism is connected with the active driving mechanism; the pedal adjusting mechanism is connected with the active driving mechanism; the chair back and the chair back support rack are in rotational connection and can alternatively be in sliding connection; the pedal and the chair surface are in rotational connection. The gravity center of the leisure sofa chair disclosed by the invention is moved backwards when the chair back tilts backwards, the chair foot slides backwards relative to the chair surface through the gravity center moving mechanism, then the gravity centers of a human body and the leisure sofa chair constantly fall on the chair foot, the phenomenon of back turnover can be prevented, and the safety of the leisure sofa chair can be improved.

Description

technical field [0001] The invention relates to the technical field of furniture, in particular to a leisure sofa chair. Background technique [0002] At present, the adjustable part of sofa chairs on the market is generally only the backrest. As the backrest moves backward, the center of gravity of the person and the sofa chair gradually moves backward. Therefore, when it is adjusted to a certain angle, it is easy to turn backwards. In order to ensure the safety of the sofa chair, the maximum adjustment angle of the backrest of the general sofa chair will not exceed 120°. People often cannot make the head, back, waist, legs and feet completely in a comfortable state after sitting on it, especially after a hard day. When fatigued, the demand for fatigue relief cannot be met, so the market demand cannot be met. Therefore, it is necessary to propose a novel leisure sofa chair to solve the above problems. [0003] The invention provides a leisure sofa chair, which can adjust ...
