The invention relates to an airbag module which is intended for users performing an activity that requires protection of the cervicodorsal region. The inventive device comprises: an expandable gas which is stored in a carboy or tank (13); at least one diffuser for the gas (14); a pyrotechnic activation system (16) for generating the expansion of the gas; at least one control signal receiver (12, 12') for activating the system; an airbag (11) which is designed to be inflated by the expansion of the gas upon receipt of a control signal; a container (10) for supporting and housing the different elements; and removable fixing means which can be positioned at multiple locations in a headrest (2) of a motor vehicle or in a helmet (1). Once inflated, the bag (11') adopts an essentially parallelepiped shape (19) (20) which extends from the base of the skull to midway down the back with lateral arms (21) which surround the neck.
