Abstract

The invention relates to the technical field of seats, in particular to a seat backrest and an adjustable seat. The seat backrest comprises a backrest body, an electric push rod, a control switch anda pressure sensor. The electric push rod is arranged in the backrest body, and the movable end of the electric push rod can extend out in the width direction of the backrest body so that the side, facing a driver, of the backrest body can protrude outwards. The pressure sensor is embedded in the backrest main body so as to detect the pressure of a driver acting on the backrest main body; the signal output end of the pressure sensor is electrically connected with the signal input end of the control switch, and the signal output end of the control switch is electrically connected with the electric push rod; when the pressure sensor detects pressure exerted on the backrest body by a driver, an electric signal can be output to the control switch, the control switch is closed, the electric pushrod is powered on and started accordingly, the movable end of the electric push rod stretches out by the preset length, the shape of the backrest body is adjusted accordingly, and the requirements ofthe driver are met.

Description

technical field [0001] The present application relates to the technical field of seats, in particular to a seat back and an adjustable seat. Background technique [0002] The working environment of the excavator is harsh and the work intensity is high. The seat is the work seat for the excavator driver. Long-term operation will cause the driver to suffer from different occupational diseases, so the demand for the back support of the seat is very high. The traditional excavator seat has a simple structure, and the inclination angle of the backrest can only be adjusted simply, and the shape of the backrest cannot be adjusted arbitrarily. However, due to the characteristics of the driver's body shape, driving habits, occupational diseases and other factors, drivers have very different requirements for the shape of the seat back. If the shape of the cushion can be set independently by the driver's own needs, it will be greatly improved. Improve the comfort and coordination of t...
