Abstract: A vehicle body includes a manifold extending transversely of the instrument panel adjacent the windshield. An oval-shaped, slotted diffuser is secured to the manifold and communicates with a source of pressure fluid. An occupant restraint cushion includes an unbilical portion communicating with the diffuser and also includes a pillow portion. The cushion is stored within the manifold. A cover is provided for the manifold. When the source of pressure fluid is communicated with the diffuser, the diffuser expands from an oval shape toward a round shape and relocates the slots during such change in shape. This moves the cover to an open position. The umbilical portion is then projected rearwardly of the body and is located between the windshield and instrument panel when inflated. The pillow portion is erected generally vertically of the body rearwardly of the frontal portion of the instrument panel.
