Head, torso and knee combo airbag

A motor vehicle airbag system comprises a dual chambered combined head, torso, and knee airbag having a head and torso chamber and a lower extremities chamber in fluid communication with the head and torso chamber. A multidirectional inflator substantially simultaneously inflates both of the head and torso chamber and the lower extremities chamber. The head and torso chamber in the inflated condition acts against a head and a torso of the motor vehicle occupant to generate a restraining force against the occupant to mitigate contact of the occupant head and torso with the upper portion of the instrument panel during the impact event. The lower extremities chamber in the inflated condition acts against the pair of knees of the occupant to mitigate contact of the knees of the occupant with the lower portion of the panel during the impact event.
