Chair lying support for assisting human body resetting

Abstract

The chair lying support for assisting the human body to reset is mainly composed of the movable assembly and the fixed assembly, and mutual switching between sitting and lying is achieved through one-time operation. In the movable assembly, a blocking piece and a connecting pin on a movable frame are rotationally connected with one ends of a plurality of fastening pieces and connected with a torsional spring. In the fixing assembly, a pressing piece connected to the fixing frame is movably connected with a long groove of a fastening piece, and when the seat is locked, the fastening piece is pressed on the pressing piece through the action of an operation piece, a compression spring and the like which are movably connected with the pressing piece. When a user sits and lies, the operating piece is operated, the fastening piece is loosened, and under the action of back force, the movable frame and the fixed frame which are rotationally connected enable the long groove of the fastening piece to move along the pressing piece till the long groove is pressed on the pressing piece. During the period, the rebound force of the torsion spring is increased, and the boss of the fastening piece is separated from the nearby part. The torsion spring assists the human body to reset to the sitting position, the operation piece is operated, and the lying support is locked. After the chair lying support is innovated, the defects of the chair lying support are overcome, the quality of the noon break chair is improved, and comfortable use of a user is met.

Description

technical field [0001] The invention relates to the technical field of furniture, in particular to a chair rest that assists the human body to reset. Background technique [0002] The chair rest is a general-purpose component mainly used for office lunch break chairs and student lunch break chairs, helping users to take lunch breaks and naps. There are two main types of chair rests in the prior art: one is a chair rest with two operating parts; the other is a chair rest with only one operating part. One of the operating parts of the former is to operate the height of the seat, and the other is to operate the angle of the seat back; one of the operating parts of the latter is to operate the angle of the seat back. The chair rest referred to herein refers to the chair rest with the function of operating the angle of the chair back, that is, it mainly includes the above two chair rests. [0003] The advantage of the chair rest with the function of operating the chair back ang...

AI Technical Summary

Problems solved by technology

Its disadvantages are: 1. Especially, the lying angle of the existing lunch break chair tends to be larger. When the lying angle is the largest, the human body can get the best lunch break state.

Such two-time locking operation and large-angle lying position bring two disadvantages to the office lunch break chair: ①The human body is reset from the maximum lying position to the sitting position, which is mainly achieved by its own strength.

In this operation, due to the distance between the back of the human body and the back of the chair, the resetting of the human body and the resetting of the chair back are not synchronized. Bringing the hidden danger of the chair back hurting the human body; Another operation is that when the person leaves the seat for operation, the large rebound force when the chair corner rests at a large angle when lying down causes the impact force generated by the rapid reset of the chair back to bring the chair The greater hidden danger of back injury to the human body

[0006] Such two-time locking operation and the maximum reclining position highlight these two deficiencies for student lunch break chairs: ①Student lunch break chairs have no armrests due to the limitation of the classroom environment, and lack of handrail support points. If the human body is reset by its own force, it will be more difficult, uncomfortable and unsmooth to reset the human body from a large-angle lying position; ②Student lunch break chairs are reset from the maximum lying position to the sitting position. If it is allowed or special attention is paid to leaning against the back of the chair, the operating parts are realized, which is relatively safe; another kind of operation is that the person sits on the seat part, and the back of the human body needs to leave the back of the chair, or leave the back of the chair inadvertently, to operate software implementation

This method only solves the problem of slow reset of the chair back and eliminates the hidden danger of injury, and the problem of uncomfortable and unsmooth reset of the human body still exists.
