To provide a parachute which can be deployed more quickly than conventional ones, a safety device including the parachute and a flying body including the safety device.SOLUTION: A canopy 40 of a parachute has a substantially hemispherical shape including a first impact cushioning part 40A, a second impact cushioning part 40B and a shape holding part 40C, and includes a vent hole 40a which is formed at a top part and a canopy skirt part 40b which constitutes an opening. The first impact cushioning part 40A and the second impact cushioning part 40B are formed in a state where a plurality of base fabric pieces are arranged such that a center line L connecting an apex P and a geometric center position of each base fabric piece intersects an extension direction of warp and weft of the base fabric pieces. The second impact cushioning part 40B is less likely to stretch the first impact cushioning part 40A, and is more likely to stretch in a direction along the center line L than the shape holding part 40C that is relatively unlikely to stretch.SELECTED DRAWING: Figure 4
【課題】従来よりも迅速に展開可能なパラシュート、当該パラシュートを備えた安全装置、および、この安全装置を備えた飛行体を得る。【解決手段】パラシュートの傘体40は、第1衝撃緩衝部40Aと、第2衝撃緩衝部40Bと、形状保持部40Cと、を備えた略半球状のものであって、頂上部に形成された通気口40aと、開口部を構成する傘縁部40bと、を有している。第1衝撃緩衝部40Aおよび第2衝撃緩衝部40Bは、頂点Pと各基布の幾何学的中心位置とを結ぶ中心線Lと、基布の縦糸および横糸の延設方向とが交差するように、複数の基布それぞれを配設した状態で形成されている。第2衝撃緩衝部40Bは、第1衝撃緩衝部40Aに比べて伸縮しにくいものではあるものの、比較的伸縮しにくい形状保持部40Cと比べて中心線Lに沿った方向に伸縮しやすいものとなっている。【選択図】図4
