Electric adjustable seat frame and seat provided with frame

Abstract

The invention discloses an electric adjustable seat frame and a seat provided with a frame, according to the technique solution, the electric adjustable seat frame comprises a backrest frame and a seat frame; the electric adjustable seat frame further comprises a backrest regulating mechanism, having a backrest regulating motor, a backrest regulating screw, a backrest regulating screw nut and an angle regulating lever; the angle regulating lever is rotatably connected with the seat frame and fixedly connected with the backrest frame at the upper end; a connecting piece fixed with the backrest regulating screw nut is actively connected with the lower end of the backrest regulating screw. The adjustable automation degree of the seat backrest and the legs is high and labour-saving due to the electric mechanism; the seat can be rotatably adjusted and the seat can be automatically locked while not rotating, the stabilization is good and the technology is improved compared with the prior art.

Description

technical field [0001] The invention relates to a seat frame, in particular to a seat frame capable of adjusting the seat back and rotating the seat left and right. Background technique [0002] With the improvement of people's demand, the function of the seat tends to be more and more comfortable to use and easy to adjust. Regarding the comfort of the seat, being able to adjust the seat back so as to flexibly suit the requirements of the user is one of the basic considerations for the seat. Known, publication number is that the patent literature of CN202193013 U discloses a kind of car seat frame, and its seat back adopts tooth plate type angle adjuster to mesh with tooth claw to adjust backrest inclination angle. Although this method has a simple structure, it needs to rotate the angle adjuster manually, the degree of automation is very low, and the adjustment is inconvenient; and due to structural limitations, the adjustment range of the backrest inclination angle is lim...

AI Technical Summary

Problems solved by technology

Although this method has a simple structure, it needs to rotate the angle adjuster manually, the degree of automation is very low, and the adjustment is inconvenient; and due to structural limitations, the adjustment range of the backrest inclination angle is limited; secondly, this kind of seat cannot be rotated freely to change the direction. In the prior art, the rotatable seat usually can only be rotated but cannot be positioned, so when a person sits on the seat, the stability in the left and right directions is poor, which cannot meet the user's convenient use requirements

In addition, the seat in the existing design usually does not have a leg pad, even if there is a leg pad, it is set separately, the integrity of the seat is not good, and there is no automatic adjustment function
