Description

Technical Field

[0001] The utility model relates to the technical field of chair headrests, in particular to a chair headrest. Background Art

[0002] As a widely used seat for people's work and life, office chairs are generally recognized and loved by people. They are also one of the indispensable furniture in modern office and home environments. As a standard configuration of high-end office chairs, whether the headrest has good comfort and practical adjustment function is what consumers pay most attention to. The earliest office chairs on the market generally had fixed headrests, but everyone's body shape is different. A headrest fixed in a certain position cannot make everyone in the best comfort position. Even if the position of the headrest is adjusted by the elastic properties of the headrest material, its reaction force will cause pressure on the head, neck and other parts of the human body. Up to now, the most common seat headrests on the market are those with lifting and adjustment functions. This type of headrest can be raised and lowered along the headrest rod to improve the comfort of the seat.

[0003] Although this type of headrest is height-adjustable to suit users of different heights, the user actually has multiple usage states when using the seat. Sometimes when you need to relax, you need to lean your head slightly back; and sometimes when you need to work on a computer, you need the headrest to protrude forward a little to provide obvious support for the head. When adjusting the height, the overall height of the headrest needs to be adjusted, which is not particularly convenient to use and cannot fully meet the user's requirements for comfort. Therefore, a headrest with adjustable overall height and adjustable height and angle of a single headrest is needed. Utility Model Content

[0053] like Figure 7 As shown, the figure is a diagram of the use state of the utility model. When in use, the overall height of the headrest assembly 1 is adjusted by moving the connecting fastener 2 on the lifting adjustment member 6, and the angle of the headrest member 5 is adjusted by the rotating assembly 12. Then, by connecting the rotating assembly 12 with the hollow track 20 in the middle of the headrest member 5, the height of the headrest member 5 is adjusted by moving up and down with the rotating assembly 12 as a fixed point.

[0054] like Figures 8 to 10 As shown, this figure is a first implementation case diagram of the utility model. An inward positioning block 25 is provided in the middle of the lower end clamping portion 17 at the front end of the base 4, and a positioning slot 26 is provided in the middle of the front side of the corresponding chair mounting frame. When in use, positioning is performed through the positioning block 25 and the positioning slot 26 on the base 4, the mounting member 13 is attached to the upper side of the chair mounting frame, and the base 4 is attached to the lower side of the chair mounting frame, so that the positioning block 25 is clamped in the positioning slot 26, and the base 4 is connected to the mounting member 13 from bottom to top with screws to complete the connection of the headrest assembly 1, which is not only easy to install, but also has a more stable connection and higher stability.
