1. An air bag assembly for cushioning restraint of an occupant in a vehicle during an impact event, the air bag assembly comprising:

  • an inflatable air bag cushion adapted to be inflated from a storage chamber beneath a dash panel of the vehicle through an elongate slotted deployment opening extending in the cross-vehicle direction, wherein the slotted deployment opening extends a length greater than the width of the occupant;

    a gas emitting inflator disposed in fluid communication with the air bag cushion adapted to distribute gas into a mouth portion of the air bag cushion; and

    at least one drag-inducing member comprising said elongate slotted deployment opening adapted to engage the air bag cushion as the air bag cushion is inflated from the stored condition to the inflated deployed condition such that deployment of the air bag cushion is retarded such that the period of energy transfer between the air bag cushion and the occupant is increased relative to unrestrained deployment from the storage chamberwherein the air bag system is adapted to deploy the air bag cushion through a portion of the dash panel facing the occupant to be protected and wherein a first portion of the air bag cushion is normally stored in folded relation forward of the inflator relative to the normal travel direction of the vehicle and wherein a second portion of the air bag cushion extends along a path below the inflator for attachment at a position between the inflator and said elongate slotted deployment opening such that upon inflation the first portion of the air bag cushion is progressively pulled along the path below the inflator and discharged through said elongate slotted deployment opening.
