Description

Technical Field

[0001] This utility model relates to the field of aircraft auxiliary equipment technology, and in particular to an adaptive hoisting backplate. Background Technology

[0002] Pilots may experience accidents during takeoff and landing for various reasons, both in wartime and during peacetime training. In the event of a flight accident at an airport, the first priority should be to ensure the pilot in distress quickly evacuates the aircraft's cockpit, and every effort should be made to guarantee the pilot's safety.

[0003] A hoisting backboard is a device used to connect to a hoisting system with steel cables to assist pilots in evacuating from the cockpit of a distressed aircraft. Existing hoisting backboards typically consist of a backboard and multiple securing straps and slings attached to it. During use, the securing straps stabilize the pilot's body, and the slings then lift the pilot, allowing them to evacuate the cockpit vertically. However, this method of securing the pilot with the backboard can lead to slippage during hoisting, potentially causing secondary injury.

[0004] Therefore, developing easy-to-operate and highly applicable pilot rescue devices to assist rescue personnel in effectively and quickly rescuing injured pilots from the aircraft cockpit has always been a key concern for airport emergency rescue. Utility Model Content

[0027] A lifting backplate is a device used to connect to the steel cables of a lifting system to assist pilots in evacuating from the cockpit of a distressed aircraft. Existing lifting backplates typically consist of a backplate and multiple securing straps and slings attached to it. During use, the securing straps stabilize the pilot's body, and the slings then lift the pilot, allowing them to evacuate the cockpit vertically. However, this method of securing the pilot with the backplate can lead to slippage during evacuation, potentially causing secondary injury. Furthermore, current protective backplates provide relatively rigid support for flight helmets, and their fit and coverage of the torso are weak. Some backplates lack anti-slip devices, while those with anti-slip features can exacerbate localized stress on the torso, causing significant pressure pain.

[0028] In view of this, this application proposes a self-adaptive lifting backplate that can stably wrap around the pilot, preventing slippage during lifting and thus fully protecting the pilot's cervical and spinal vertebrae, preventing secondary injury to the pilot in distress.
