Emergency protective helmet

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.

1 . An emergency protective helmet comprising a round-the-neck storage support, a series of curved elements mounted movably in rotation with the round-the-neck storage support and with one another at their ends so as to be able to pass 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 round-the-neck storage support, wherein the emergency protective helmet further comprises a compressed gas cartridge and a set of flexible tubes fluidically connected to the cartridge and connecting the curved elements to one another, the flexible tubes being arranged such that inflating the flexible tubes causes the curved elements to pass from the second, stowed position to the first, deployed position. 
     
     
         2 . The emergency protective helmet as claimed in  claim 1 , wherein it comprises a control and drive unit, arranged to initiate a triggering of the cartridge, comprising a position/angle sensor and a speed sensor. 
     
     
         3 . The emergency protective helmet as claimed in  claim 1 , wherein the curved elements are rigid hoops. 
     
     
         4 . The emergency protective helmet as claimed in  claim 1 , wherein it comprises a flexible fabric connecting the curved elements to one another. 
     
     
         5 . The emergency protective helmet as claimed in  claim 1 , wherein it further comprises a base capable of resting on the shoulders of a wearer, the round-the-neck storage support being mounted movably on the base. 
     
     
         6 . The emergency protective helmet as claimed in  claim 5 , wherein the round-the-neck storage support is mounted movably in translation on the base. 
     
     
         7 . The emergency protective helmet as claimed in  claim 5 , comprising a device for adjusting the position, according to the morphology of the wearer, of the round-the-neck storage support relative to the base. 
     
     
         8 . The emergency protective helmet as claimed in  claim 5 , further comprising a shoulder airbag fluidically connected to the cartridge and arranged such that inflation of the airbag moves the round-the-neck storage support vertically upward. 
     
     
         9 . The emergency protective helmet as claimed in  claim 1 , further comprising a quick-release buckle. 
     
     
         10 . The emergency protective helmet as claimed in  claim 9 , wherein the quick-release buckle comprises an arming switch.
