Office Chair Accessories Patent

Here is an introduction to some patent information related to office chair accessories:

Patent for Stable Office Chair Accessories: This patent focuses on solving the problem of the office chair's center of gravity shifting backward when the backrest angle is adjusted too much. Its adjusting component has a unique design. A hinge is installed between the seat plate and the backrest. A wing plate is fixed on the side surface of the cylinder adjusting base, and a first electric linear actuator is rotatably installed between the wing plate and the backrest. Through this structure, the backrest angle can be adjusted. Regarding the supporting components, seven supporting rods are arranged in an array on the side of the lower end of the pneumatic lifting rod. Two universal wheels are installed on the lower surface of each supporting rod, facilitating the movement of the office chair. At the same time, a second electric linear actuator is fixed inside the supporting rod, with its telescopic end fixed at the lower end of the pneumatic lifting rod. A guide rod is also fixed at the lower end of the pneumatic lifting rod. These designs collectively improve the stability of the office chair after adjusting the backrest inclination angle^[2].

Patent for a Lumbar Support Device with Adjustable Inclination: The lumbar support device in this patent includes a lumbar support body and a connecting base. The rear side of the lumbar support body is recessed to form a rotating support groove. The support part of the connecting base is located inside the rotating support groove and is movably connected to the lumbar support body, and there is a gap between them in the vertical direction, forming a rotating clearance. With this rotating clearance, the lumbar support body can rotate back and forth relative to the support part to adjust the inclination angle. It can adaptively rotate and adjust according to the curved surface of the mesh fabric, providing a more comfortable sitting experience for the user^[3].

Patent for Adjustable-Angle Office Chair Armrests: This patent achieves backrest angle adjustment through the mutual cooperation among the first worm gear, the first worm, the rotating rod, the rotating part, and the connecting part. This design allows office workers to recline and rest on the office chair, effectively improving the comfort of the seat^[4].

Patent for an Office Chair with Posture Correction Function: Its design principle is that when the user leans backward, the waist comes into contact with and presses the massage plate, causing it to move backward. This, in turn, drives the support plate to move. Through the deformation of the first elastic component, it provides support to the waist, preventing the waist from bending during sitting and thus playing a role in posture correction^[4].
