Comfortable chair bracket with zero-gravity adjusting function

Abstract

The invention relates to the technical field of comfortable chairs, in particular to a comfortable chair support with a zero-gravity adjusting function, which comprises a framework, a base, a turnover mechanism and a telescopic driving element, the turnover mechanism is movably connected between the base and the framework, and the turnover mechanism comprises a fixed plate arranged at the top of the base and a turnover plate arranged at the bottom of the framework. Vertical plates extending upwards are arranged on the left side and the right side of the fixing plate, connecting plates extending downwards are arranged on the left side and the right side of the turnover plate, the distance between the two connecting plates is larger than that between the two vertical plates, the connecting plates are located on the outer sides of the vertical plates, connecting bolts movably connected with the vertical plates are arranged on the connecting plates, and the tail end of the telescopic driving element is movably connected with the fixing plate. The output end of the telescopic driving element is connected with the bottom of the framework, a limiting column is arranged on the outer wall of the vertical plate, an arc-shaped limiting hole matched with the limiting column is formed in the corresponding position of the connecting plate, the rear side of the vertical plate is an inclined face, and the comfortable chair support has the flexible zero-gravity adjusting function, zero-gravity adjustment is safe and reliable, the service life is long, the structure is simple, and cost is low.

Description

technical field [0001] The invention relates to the technical field of comfortable chairs, in particular to a bracket for a comfortable chair with a zero-gravity adjustment function. Background technique [0002] A comfortable chair refers to a chair with multiple functional adjustments, which can bring people a sense of physical relaxation and comfort. At present, the main adjustment functions of a comfortable chair include backrest inclination adjustment, headrest angle adjustment, leg rest (or footrest) angle adjustment, and the like. The comfortable chair also has another function - zero-gravity adjustment function. The zero-gravity adjustment function is to adjust the overall angle of the comfortable chair so that the human body is in a state of no pressure. In the zero-gravity adjustment state, the human body is similar to In the suspended state, because it is not under pressure, it has a relatively good comfortable chair. This function can effectively improve the com...

Problems solved by technology

The realization of this function mainly depends on the adjustment of the frame of the comfortable chair. The overall angle of the frame can be flipped and adjusted. Generally, this function is only available on relatively high-end chairs. The structure is complex and the cost is relatively high.
