1. An airbag module comprising:
- an airbag inflatable through an opening in the airbag;
an airbag inflator for providing an inflation gas into said opening in the airbag;
an airbag housing to which the airbag inflator and the airbag are attached;
a flap attached to said housing, said flap being movable from a first position permitting inflation gas to flow to said opening in the airbag and a second position deflecting the inflation gas away from said opening in the airbag; and
a propellant capable of discharging into a discharge space, said propellant moving said flap between said first position and said second position when discharged; and
a hood at least partially covering said discharge space.

Abstract
An airbag module comprises an airbag inflatable through an opening in the airbag. An airbag inflator provides an inflation gas into the opening in the airbag. A flap has a first position permitting gas to flow to the opening in the airbag and a second position deflecting inflation gas away fro the opening in the airbag. A propellant discharges into a discharge space moving the flap between the first position to the second position. A hood at least partially covers the discharge space.

9. An airbag module comprising:
-
an airbag inflatable through an opening in the airbag;
an airbag inflator for providing an inflation gas into said opening in the airbag;
a flap in communication with said airbag inflator, said flap having a first position permitting inflation gas to flow to said opening in the airbag and a second position deflecting the inflation gas away from said opening in the airbag;
a propellant capable of discharging into a discharge space, said propellant moving said flap between said first position and said second position when discharged;
a propellant housing storing said propellant, said propellant housing having a first electrical contact and a second electrical contact in communication with said propellant;
a first hollow body receiving said propellant housing; and
a piston slidably received in said first hollow body, said piston having an actuated position following discharge of said propellant into said space and an unactuated position prior to discharge of said propellant into said discharge space, wherein at least a portion of said piston protrudes further outside of said first hollow body in said actuated position than in said unactuated position. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
