Description

A massage office chair with manually adjustable massage positions

technical field

The present invention relates to an office chair, more specifically, to a massage office chair with manual control to adjust the massage position.

Background technique

The competition in modern society is fierce, the pace of life is accelerated, and the pressure of life is increasing. The reduction of activity space and time makes people's body and spirit unable to relax. Those white-collar workers, engineering technicians and even students who often sit in front of computers and study with computers all year round have various "sedentary syndromes" such as severe decline in physical fitness, obesity, cervical spondylosis, and lumbar disc herniation. And this phenomenon has a further serious tendency.

Massage chairs are more and more popular among consumers as a health care and medical device for eliminating fatigue, especially the appearance of automatic massage chairs, which greatly improves the comfort of use. There are endless massage chairs on the market, but most massage chairs are driven by electric motors, which use motors to change the massage position, but the price is relatively expensive. Not only does it consume a lot of power during operation, but the speed and intensity of massage are relatively fixed and mechanical. It often makes people feel uncomfortable, and even often fails to meet the massage effect requirements. Moreover, the existing common massage chairs are often relatively huge in size, and are not suitable for being directly placed in offices.

Chinese patent number ZL201310152548.3, the date of authorization announcement is July 29, 2015, the name of the invention is: multifunctional office chair, the application involves a multifunctional office chair, including a chair frame, a chair cushion, a chair back assembly, Armrests, massage components and connection components. There are 2 armrests, and the 2 armrests are respectively fixedly arranged on the left and right sides of the chair cushion. The main points are: the massage assembly is arranged on the rear side of the chair back assembly for massaging the back of the human body. The connection assembly includes a fixed plate, a connection frame, a tie rod, a torsion spring and a seat cushion guide rail assembly. The fixing plate is fixedly arranged on the chair frame. The connecting frame is fixedly arranged on the fixed plate, and the chair cushion is fixedly arranged on the fixed plate through the chair cushion guide rail assembly. The seat back assembly is rotatably connected to the connecting frame, and the seat cushion and the seat back assembly realize linkage through the pull rod. When the seat back assembly is lying down, the pull rod drives the seat cushion to move away from the seat back assembly on the seat cushion guide rail assembly. The torsion spring is arranged on the chair back assembly and the connection assembly, and is used for resetting after the chair back assembly is lying down. The office chair in this application also has a massage function, but it is not difficult to find that the massage position is realized by the screw nut pair driven by the motor, and the lifting movement of the massager drives the massager to move laterally to both sides. Although the structure is relatively simple, the movement of the massager is relatively mechanical, and the lateral position adjustment of the massager is also subject to great limitations, which is not flexible enough, resulting in a greatly reduced massage comfort of the massage chair, which seriously affects the massage experience of consumers. In addition, the office chair is also equipped with a storage assembly, which is arranged on one side of the seat. Although the storage assembly can be folded on the side of the seat when not in use, reducing the floor space, the folded storage assembly Also can cause interference to the use of seat, practicality is relatively poor.

There are also massage chairs that adopt manual control on the market, but these massage chairs mostly use manual control massage balls to beat the user's back, and there are few massage chairs that use manual control mechanisms to change the massage position.
