Aerial vehicle safety apparatus and method of accommodating expandable object in aerial vehicle safety apparatus

An aerial vehicle safety apparatus comprising:

• an expandable object configured to hold air inside during expansion;
• a container that accommodates the expandable object in an initial state;
• a hat-shaped member provided in the container and including a columnar member and a flange provided at one end of the columnar member;
• and
• an ejection apparatus that ejects the hat-shaped member and the expandable object from inside of the container to outside of the container at time of operation,
• wherein in the initial state, the expandable object is accommodated in the container while being folded into layers including at least
• a first layer configured by arranging the expandable object to be positioned at a predetermined position on the flange with one end of the expandable object as a starting end from a state in which the expandable object is collected into an elongated shape, extending the expandable object on the flange by one round about the columnar member from the starting end, and forming a terminal end, and
• a second layer configured by folding back the expandable object from the terminal end of the first layer to overlap the first layer on an opposite side of the flange, further extending the expandable object around the columnar member by one round along a surface of the first layer to reach one end of the first layer, and layering the expandable object on the first layer in a direction opposite to the flange.

• and
• forming a second layer by folding back the expandable object from the terminal end of the first layer to overlap an outer side of the first layer, further extending the expandable object around the first layer along a peripheral surface of the first layer by one round to reach one end of the first layer, and layering the expandable object on the first layer in a radial direction.
