Seat

Abstract

The invention relates to a seat. The seat comprises a backrest, a seat frame and armrest frames arranged at the two sides of the seat frame, wherein the left side and the right side of the backrest are respectively hinged with two armrest frames, the two sides of the rear end of the seat frame are respectively hinged with the left side and the right side of the backrest, a hinge joint of the backrest and the armrest frames and a hinge joint of the seat frame and the backrest are different in position, the front end of the seat frame is rotatably and slidably connected with armrest frames, the backrest rotates and drives the seat frame to move front and back, and an elastic resetting mechanism is arranged at the hinge joint of the backrest and the armrest frames or the hinge joint of the seat frame and the backrest; and the elastic resetting mechanism is arranged at the hinge joint of the backrest and the armrest frames or the hinge joint of the seat frame and the backrest, adopts hidden design and provides a restoring force for movement of the backrest and the seat frame without occupying extra space, and the seat can reset when the backrest is turned over in an unloaded state, so that overall design is more concise, and volume is saved.

Description

technical field [0001] The invention relates to a seat, in particular to a leisure chair. Background technique [0002] When people are entertaining indoors and outdoors, leisure chairs are often used; the backrest of general leisure chairs can be tilted backwards to provide the best relaxing posture. [0003] At present, many leisure chairs have not studied the human-machine size matching relationship between the backrest and the seat surface. When the user is reclining, the seat backrest, especially the lumbar support, is separated from the waist of the human body, and the two directly form a suspension gap, resulting in the reclining state. The seat loses support for the human waist, which is what we commonly call "running the waist". The lack of effective support for the human spine leads to many health problems caused by sedentary sitting, and the rest cannot be well relaxed; at the same time, the user is reclining. , The buttocks and the seat surface are relatively fi...

Problems solved by technology

[0003] At present, many leisure chairs have not studied the human-machine size matching relationship between the backrest and the seat surface. When the user is reclining, the seat backrest, especially the lumbar support, is separated from the waist of the human body, and the two directly form a suspension gap, resulting in the reclining state. The seat loses support for the human waist, which is what we commonly call "running the waist". The lack of effective support for the human spine leads to many health problems caused by sedentary sitting, and the rest cannot be well relaxed; at the same time, the user is reclining. , the buttocks and the seat surface are relatively fixed, while the seat back rubs upward against the back of the human body, causing the discomfort of "rubbing the back and pulling clothes" and also causing an unsightly appearance

[0004] Therefore, in view of the above problems, it is necessary to design a leisure chair with synchronous movement of the seat back to solve the above problems, but it is necessary to add an elastic reset mechanism to help the leisure chair reset. Usually, the leisure chair is designed to be relatively large, and it is reset by a tension spring to a large extent. It will increase the volume of the seat frame, and the space is not enough to save, so that the whole is not beautiful. Therefore, it is a problem to be solved at present to design a leisure chair with a seat back that moves synchronously and saves space.
