Abstract

A folding and sliding head and neck protection device for ejection of fighter jets relates to the field of ejection and life-saving. A lateral protection mechanism is slidably fitted on the guide rod. A compression spring is arranged between the lateral protection mechanism and the mounting base. The compression spring is sleeved on the guide rod. A rotating base is installed on the lateral protection mechanism. The upper part of the base is provided with a headrest panel recovery mechanism, and the headrest panel recovery mechanism is connected with the top of the headrest panel through a traction rope. On the premise that the overall occupied space is small, the structure is relatively simple, the work is stable, and the lateral protection mechanism has a certain buffering effect, the pilot's head and neck are restricted to a designated position during the ejection process, and the head and neck swinging motion under unfavorable loads is reduced. resulting risk of injury.

Description

technical field [0001] The invention relates to the technical field of ejection and lifesaving for pilots, in particular to a folding and sliding head and neck protection device for a fighter ejection seat. Background technique [0002] Ejection rescue is an important means for fighter pilots to escape from crashed aircraft. However, during the ejection lifesaving process, the pilot's head and neck will be subjected to adverse loads such as high-G vertical impact loads and high-speed airflow blowing in multiple directions, causing the pilot's head and neck to swing in different directions, which may cause the pilot's head and neck. Injuries to critical parts may even lead to the death of the pilot. [0003] In recent years, the research on pilot head and neck protection devices at home and abroad mainly revolves around mechanical and airbag deployment. Although the airbag type occupies a small space when not working, has a large contact area with the pilot's head when it i...
