1. In combination with a vehicle having an interior within which is an occupant carrying location, structure spaced from said location, and a crash restraint apparatus for protecting an occupant in said location from impact with said structure, said apparatus comprising:

  • a. a structure defining an aspirating passageway having an upstream inlet opening to admit an inflow of aspirating air and a downstream outlet opening, b. a collapsed inflatable mounted proximate said outlet opening and arranged to be inflated by gas flowing from said outlet opening to a position between said passenger location and said structure, c. a plurality of aspirating jet units, each having a discharge axis and disposed in said passageway to emit a plurality of aspirating jet streams in a downstream direction, and d. means to provide a short sustained velocity of gas from said jet units through said outlet, the improvement comprising a generally transverse manifold tube, a first set of jet units mounted to the manifold tube with their discharge axes directed generally parallel to said downstream direction, a second set of jet units mounted to the manifold tube with their discharge axes canted moderately to one side from said downstream direction, and a third set of jet units mounted to the manifold tube with their discharge axes canted moderately to a generally opposite side from said downstream direction, whereby said aspirating jet streams diverge to provide a relatively wide aspirating pattern in the passageway.
