PROBLEM TO BE SOLVED: To provide an impact buffer which can protect an aircraft body and devices mounted thereon from impact caused during falling or the like, and to provide an airbag device including the impact buffer.SOLUTION: An impact buffer 100 includes a leg part 11 which is coupled to a coupling member 10 used for coupling to a drone body at one end part. The leg part 11 includes: a cylindrical member 1 directly coupled to the coupling member 10; a cylindrical member 2 which is inserted into the cylindrical member 1 and may slide in a length direction; a piston part 3 which is inserted into the cylindrical member 2 and may slide in the length direction; and a lid part 4 which is provided at a tip of the piston part 3 and is a portion grounded when the drone lands or the like. An igniter 12 provided in the cylindrical member 1, the cylindrical members 1, 2, the piston part 3, and the lid part 4 form a pyro-actuator.SELECTED DRAWING: Figure 1
【課題】航空機本体および搭載デバイスを落下時等の衝撃から保護できる衝撃緩衝装置、および、この衝撃緩衝装置を備えたエアバッグ装置を得る。【解決手段】衝撃緩衝装置100は、ドローン本体との結合に用いられる結合用部材10に一端部が結合されている脚部11を備えている。脚部11は、結合用部材10に直接結合されている筒状部材1と、筒状部材1に内挿され、長さ方向にスライド可能な筒状部材2と、筒状部材2に内挿され、長さ方向にスライド可能なピストン部3と、ピストン部3の先端に設けられ、ドローンが着地する等する場合に接地する部分となる蓋部4と、を備えている。筒状部材1に設けられた点火器12と、筒状部材1、2と、ピストン部3と、蓋部4とで、パイロアクチュエータを構成している。【選択図】図1
