The invention discloses an ejection seat headrest assembly resistant to high-speed airflow blowing. The assembly comprises a hard headrest and a headrest cover, the hard headrest is installed on a seat umbrella box through headrest supports on the two sides of the rear portion of the hard headrest, the headrest cover is laid in front of the hard headrest, the headrest cover comprises two layers of cloth pieces and a soft cushion wrapped between the two layers of cloth pieces, the outer side face of the headrest cover is provided with two cover pieces used for limiting and fixing escape parachute control belts, the cloth pieces and the cover pieces are both made of breathable three-dimensional mesh fabric, and in the working process, the two escape parachute control belts stretch out of the bottom of the seat parachute box, are wound to the upper portion from the rear portion of the hard headrest and then penetrate through the two cover pieces downwards to be connected with shoulder straps of a pilot. High pressure generated by high-speed airflow can be reduced, it is guaranteed that the escape parachute control belt cannot be pulled out due to the high pressure generated by the high-speed airflow, the structure is simple, and the weight is light.
本发明公开了一种耐高速气流吹袭的弹射座椅头靠组件,包括硬质头靠和头靠罩,硬质头靠通过后面两侧的头靠支座安装在座椅伞箱上,头靠罩铺放的设在硬质头靠的前面,头靠罩包括两层布片以及包裹在两层布片之间的软垫,头靠罩外侧面设有两道用于限位固定救生伞操纵带的盖片,布片和盖片均采用可透气的三维网眼织物,工作时,两条救生伞操纵带从座椅伞箱底部伸出,从硬质头靠后方绕至上方,再向下分别穿过两道盖片后与飞行员肩带连接。本发明可以减轻高速气流产生的高压,保证救生伞操纵带不会因为高速气流产生的高压而拉出,结构简单,重量轻。
