Abstract: An airbag module comprises a control unit, a source of electric current managed by the control unit, a container wherein a gas is stored under pressure, and a hollow body with an inlet duct, in which an outlet of the container sealed by a pierceable membrane is tightly fitted, and an outlet duct on which an inflatable bag is tightly assembled. The airbag module further comprises an actuator assembly configured to pierce open the membrane sealing the container, said actuator assembly comprising a piercing member movably restrained to the body and at least one linear shape memory alloy wire actuator member that is electrically connected to the source of electric current and operably restrained to the piercing member so as to cause it to move beyond the pierceable membrane.
