Abstract: The application relates to a bag for transporting fragile objects, including a rigid or semi-rigid outer envelope delimiting an internal volume, partitioning elements for partitioning said internal volume, means for opening the envelope in order to access the internal volume, and means for linking to a carrier. The bag further includes a security device arranged so as to cooperate with the opening means.

Abstract: The emergency protective helmet includes a storage support worn about the neck, a series of curved elements mounted movable in rotation with the storage support worn about the neck and with each other at their ends so as to be able to switch between a first, functional deployed position, in which the curved elements form a protective structure, and a second, non-functional stowed position, in which the curved elements are housed in the storage support worn about the neck, the emergency protective helmet further including a compressed gas cartridge and a set of flexible tubes fluidically connected to the cartridge and connecting the curved elements to each other, the flexible tubes being arranged such that inflating the flexible tubes switches the curved elements from the second, stowed position to the first, deployed position.
