Abstract

A folding sliding type head and neck protection device for catapulting of a fighter relates to the field of catapulting lifesaving and comprises a mounting base, a headrest panel is rotatably connected to the middle of the mounting base, a plurality of guide rods are arranged on the mounting base, and lateral protection mechanisms are slidably matched with the guide rods. A compression spring is arranged between the lateral protection mechanism and the mounting base, the compression spring is connected to the guide rod in a sleeving mode, a rotating base is mounted on the lateral protection mechanism, a headrest panel recycling mechanism is arranged on the upper portion of the mounting base, and the headrest panel recycling 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 simple, work is stable, and the lateral protection mechanism has a certain buffering effect, the head and neck of a pilot are limited to the designated position in the ejection process, and the damage risk caused by head and neck throwing movement under adverse loads is reduced.

Description

technical field [0001] The invention relates to the technical field of pilot ejection lifesaving, in particular to a folding and sliding head and neck protection device for an ejection seat of a fighter jet. Background technique [0002] Ejection rescue is an important means for fighter pilots to escape from crashed aircraft. However, during the ejection rescue 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, which will cause the pilot's head and neck to swing in different directions, and at least cause the pilot's head and neck Damage to key parts may lead to the death of the pilot. [0003] In recent years, domestic and foreign research on head and neck protection for pilots has mainly focused on mechanical and airbag protection. Although the airbag type takes up little space when it is not working, and has a large contact area with the pilot's head when it is...
