Intended to be used by users whose activity requires cervical and dorsal protection, it comprises an expandable gas stored in a bottle or tank (13); at least one diffuser for the gas (14); a pyrotechnic activation system (16) to bring about the expansion of the gas; at least one control signal receiver (12, 12') for activation of the system; an airbag (11) adapted to be inflated by the expansion of the gas when a control signal is received; a receptacle (10) for the support and housing of the different elements and a removable and multi-positionable fixing means to the headrest (2) of an automobile or to a helmet (1). Once inflated, the bag (11') has an essentially parallelipipedic shape (19), (20), spanning from the base of the skull to half-way down the back, with lateral wings (21) which enshrine the neck. |
