This application relates to the field of high-altitude protective clothing technology, specifically disclosing a wearable high-altitude
fall protection airbag device, including: a safety suit, an
airbag assembly embedded in the safety suit, a
gas generator connected to the air circuit of the
airbag assembly, a sensor group for collecting
human motion data, and a
microcontroller electrically connected to the
gas generator and the sensor group respectively; the airbag
assembly includes multiple double-layer combined airbags, each double-layer combined airbag including an inner airbag and an outer airbag covering the inner airbag; the inner airbag is a sealed airbag, and the outer airbag is a venting airbag equipped with a
dynamic pressure relief valve; the device also includes an airbag
internal pressure sensor disposed inside the double-layer combined airbag, and the airbag
internal pressure sensor is electrically connected to the
microcontroller; the present invention proposes an inner and outer double-layer structure and a
dynamic pressure relief valve, which improves the overall safety protection effect by connecting the initial deceleration of the
dynamic pressure relief of the outer venting airbag with the rigid support at the end of the inner sealed airbag.
