Seating and lying two-purpose seat system

Abstract

The invention provides a seating and lying two-purpose seat system. The system consists of a front leg pipe system, a back leg pipe system, a slide rail, a seat, a backrest, a positioning pin, a hinge pipe and casters, wherein a joint face of the slide rail is connected with an upper horizontal pipe of the front leg pipe system, and the other joint face of the slide rail is connected with an upper horizontal pipe of the back le pipe system; the front leg pipe system is connected with the back leg pipe system in a sliding way; a backrest hinge on the back part of the backrest is hinged with through holes of two backrest pipes of the back leg pipe system; the positioning pin is connected to the upper horizontal pipe of the front leg pipe system; a pin column of the positioning pin passes through a hole on the upper horizontal pipe of the front leg pipe system and is inserted into a hole of the upper horizontal pipe of the back leg pipe system; the outer wall of a casing of the hinge pipe is connected with the backrest; and a hinge seat is connected with the upper horizontal pipe of the front leg pipe system. The seat system has the advantages that: the seat can be used for seating and lying; the gravity center of the seat system can be adjusted automatically; and the inclination angle of the backrest is fixed and adjustable.

Description

technical field [0001] The invention belongs to the technical field of furniture products, in particular to a structure of a seat system. Background technique [0002] Most of the existing seat systems can only sit, not lie down. Certain reclining seating systems utilize the reclining of an adjustable backrest. But its shortcoming is: one, " can only sit, can not lie down " seat system is unfavorable for simulating people's noon rest. 2. The center of gravity of the seat system "realized by reclining the adjustable backrest" is fixed and not adjustable, so the reclining angle of the backrest is limited, or a larger chassis is required to increase the range of the center of gravity. The "A Seat System That Can Sit and Recliner" (200920131627.5) that I applied for before can solve the above problems, but its disadvantages are: 1. The inclination angle of the backrest during rest is completely determined by the gravity of the simulated human body, so it is possible to fall in...

AI Technical Summary

Problems solved by technology

But its disadvantages are: 1. The seat system of "can only sit, not lie down" is not conducive to simulating the rest of the human body at noon

2. The center of gravity of the seat system "realized by reclining the adjustable backrest" is fixed and not adjustable, so the reclining angle of the backrest is limited, or a larger chassis is required to increase the range of the center of gravity

The "A Seat System That Can Sit and Recliner" (200920131627.5) that I applied for before can solve the above problems, but its disadvantages are: 1. The inclination angle of the backrest during rest is completely determined by the gravity of the simulated human body, so it is possible to fall into the simulated uncomfortable angle

2. Use elastic force to control the state of sitting and lying down, the effect is relatively poor
