摘要： An aerial vehicle safety apparatus includes a safety mechanism, a drive mechanism, an ejection mechanism, and a control mechanism. The safety mechanism is used for securing safety of at least one of an aerial vehicle and an object outside the aerial vehicle. The drive mechanism includes at least one drive unit serving as a drive source of the safety mechanism. The ejection mechanism ejects the drive mechanism together with the safety mechanism. The control mechanism controls operations of the drive mechanism for the drive mechanism to drive the safety mechanism after the ejection mechanism starts ejection of the safety mechanism.

摘要： There are provided a safety apparatus and an aerial vehicle including the safety apparatus, in which a lid and an opening end of a container are fixed before operation more firmly than a conventional art to be less susceptible to an external environment. A safety apparatus includes a piston member, a cylinder that accommodates the piston member and is provided with a bore through which the piston member protrudes to the outside during operation, a push-up member that is pushed up in one direction by the piston member, an ejected object 16 that is pushed up while being supported by the push-up member, a gas generator that moves the piston member in the cylinder, and a lid 21 including a projection 21a. The projection 21a includes a second through hole 21c, and an engagement mechanism is configured when a pin member 22 is inserted into the second through hole 21c and a first through hole 18a provided in a container 18 to engage an opening end of the container 18 and the projection 21a.

摘要： A gas generator includes a housing and a partition portion dividing a space in the housing into a combustion chamber accommodating a gas generating agent and a filter chamber accommodating a filter. The partition portion includes a first region which opens at the time of activation by being located to be opposed to a hollow portion of the filter and an annular second region which does not open even at the time of activation by being located to be opposed to a portion of an axial end surface of the filter except for the hollow portion. The second region is provided with a large-thickness portion constructed to be greater in thickness than the first region and opposed to an outer edge portion of the axial end surface of the filter, and the large-thickness portion is constructed to gradually be greater in thickness from an inner circumferential end portion toward an outer circumferential end portion.

摘要： There is provided a safety apparatus including a push-up member in which an ejected object is hardly displaced even during transportation, and an aerial vehicle including the safety apparatus. A safety apparatus 100 includes a cylinder 14 that accommodates a piston member 10 and is provided with a bore 13 through which the piston member 10 protrudes to the outside (upward in FIG. 1) during operation, a push-up member 15 that is pushed up in one direction by the piston member 10, an ejected object 16 that is pushed up while being supported by the push-up member 15, a gas generator 17 as a power source that moves the piston member 10 in the cylinder 14, a container 18 that has a bottomed cylindrical shape and accommodates the piston member 10, the cylinder 14, the push-up member 15, the ejected object 16, and the gas generator 17, and a lid 21 that closes an opening end of the container 18. A movement preventing member 27 that prevents the ejected object 16 from moving in a circumferential direction of a bottomed cylindrical portion 19 is provided on an upper surface of a support 20 of the push-up member 15.

摘要： An aerial vehicle safety apparatus includes an expandable object, an ejection apparatus, a bag-shaped member, and a gas generator. The expandable object is wound or folded in a non-expanded state and generates at least any of lift and buoyancy in an expanded state. The ejection apparatus is coupled to the expandable object by a coupling member and ejects the non-expanded expandable object into air. The bag-shaped member is provided in the expandable object and wound or folded together with or separately from the non-expanded expandable object, and expands the non-expanded expandable object by at least partially being inflated like a tube. The gas generator is provided in the expandable object and inflates the bag-shaped member by causing gas generated at the time of activation to flow into the bag-shaped member.

摘要： A gas generator includes a partition portion, a cylindrical portion, and a separation wall portion which divide a space in a housing into a first combustion chamber, a second combustion chamber, a gas passage chamber, and a gas emission chamber. The first combustion chamber includes a space inside the cylindrical portion on a side of an igniter relative to the separation wall portion, and the second combustion chamber includes the space inside the cylindrical portion on a side of the partition portion relative to the separation wall portion. The gas passage chamber includes a space outside the cylindrical portion which faces a circumferential wall portion of the housing, and the gas emission chamber includes a space on a side of a gas discharge opening relative to the partition portion. At least some of a gas generated in the first combustion chamber at the time of activation of the gas generator is emitted to the outside sequentially through the gas passage chamber, the second combustion chamber, and the gas emission chamber.
