Abstract
The inflatable safety cushion for a vehicle comprises an electric arming device (19) which is capable of detecting a dangerous situation and of very rapidly actuating a pyrotechnic gas generator for triggering said safety cushion, and which is powered by a cell (12). It also comprises an arming device (20, 21) for detecting that the vehicle is being used in order automatically to arm the device (19) as soon as it is detected that the vehicle is being used, and a device (21a) for interrupting the armed state as soon as, for a predetermined length of time, no use of the vehicle has been detected.
