Description

TECHNICAL FIELD

[0001] The utility model relates to the field of office chair, especially an office chair net seat structure. BACKGROUND

[0002] Chair refers to various chairs equipped for work convenience in daily work and social activities. With human body design for sitting posture, ergonomic chair is also born, which provides bionic support for positions such as lumbar vertebrae or cervical vertebrae of human body, thereby reducing the load of human body, and improving comfort, and avoiding sub-health problems caused by bad sitting posture.

[0003] The lumbar support of the office chair is generally provided as an adjustable structure, thereby achieving adjustment in the height direction and the fit of the waist. The existing method is generally divided into two kinds: 1. The cooperation of concave-convex blocks or dampers is used to achieve the adjustment of the lumbar support, so the resistance of the matching structure is large, and the convenience of use is poor for women or users with less strength; 2. Of course, there is also a locking structure provided with sliding, but the existing locking structure is generally provided at the middle position of the lumbar support, so the adjustment is also troublesome. SUMMARY

[0004] The main purpose of the utility model is to provide an office chair net seat structure, which aims to improve the existing lumbar support structure, so that it is used as a separate module, thereby facilitating assembly, and at the same time, through the side-mounted locking structure, the adjustment of the position of the support is facilitated.

[0005] To achieve the above-mentioned purpose, the utility model provides an office chair net seat structure, which comprises:

[0006] The base is provided with guide protrusions on both sides of the front wall, and a plurality of clamping blocks along the length direction are arranged on one side of the front wall of the base, and a locking groove is arranged between the two clamping blocks;

[0007] The net seat is provided with a guide groove matched with the guide protrusion, and the guide protrusion can slide along the length direction of the guide groove,

[0008] The side wall of the net seat is provided with a horizontally sliding locking strip, and the inner side end of the locking strip can move between the position clamped into the locking groove and the position away from the locking groove.

[0009] By improving the existing net seat structure, it becomes a module structure installed on the positions of office chairs, seats, car seats, etc. When the base is installed on the predetermined seat, the fit of the waist and the front wall of the net seat can be adjusted according to the actual demand, thereby adjusting the support degree and improving the use experience. At the same time, the locking strip and the clamping block are arranged at the side end position, which can reduce the stroke of the locking structure, and also facilitates the on-off adjustment, avoiding the problem that the existing locking device is troublesome to adjust, and the structure is relatively simple.
