The invention relates to a seat for engineering machinery, which comprises a backrest, a headrest is arranged above the backrest, a mounting groove is arranged at the top of the backrest, the headrest is mounted in the mounting groove, two sides of the headrest are respectively connected with the mounting groove through a mounting component, the mounting component comprises a rotating shaft, a limiting shaft and a nut, one end of the rotating shaft is fixed on the side surface of the headrest, and the other end of the rotating shaft is fixed on the limiting shaft. The other end of the rotating shaft is provided with a screw hole, a fixing unit and a locking unit, mounting holes are formed in the two side walls of the mounting groove, and the fixing unit and the locking unit are mounted in the mounting holes; the locking unit comprises a plurality of elastic pieces, one ends of the elastic pieces are fixed to the end of the rotating shaft, friction blocks are fixed to the other ends of the elastic pieces, and the nut comprises a threaded part and an inclined part. The headrest rotates around the rotating shaft, so that the angle of the headrest relative to the backrest is adjusted, different requirements of operators with different body types can be met, and the comfort level of the seat is improved; the locking structure is simple and easy to operate, and the requirement for improving the comfort degree of the seat at low cost is met.

    本发明涉及一种用于工程机械的座椅,包括靠背,靠背上方设有头枕,靠背顶部设有安装槽,头枕安装在安装槽内,头枕的两侧分别通过安装组件与安装槽连接,安装组件包括转动轴、限位轴和螺帽,转动轴的一端固定在头枕的侧面,转动轴的另一端具有螺孔、固定单元和锁紧单元,安装槽的两侧壁均开设有安装孔,固定单元和锁紧单元均安装在安装孔内;锁紧单元包括多个弹片,弹片的一端与转动轴的端部固定,弹片的另一端固定有摩擦块,螺帽包括螺纹部和倾斜部。本发明的头枕绕转动轴转动从而调节头枕相对于靠背的角度,能够适用于不同体型操作人员的不同需求,提高座椅的舒适度;锁紧结构简单且易操作,实现了较低成本下提高座椅舒适度的需求。
