Abstract
A side impact air bag module (10) includes an air bag (12) having a body portion (330) which is inflatable into a position between a vehicle occupant and a side structure (54) of the vehicle (40). The air bag (12) and an inflator (14) are secured to a base plate (18) which supports the inflator and the air bag on the vehicle (40). A chute (24) is connected with the base plate (18) for storing the air bag (12) in the chute and for guiding the air bag to inflate into a position between the vehicle occupant and the vehicle side structure (54). A neck portion (300) of the air bag (12) is connected with the base plate (18) at a location outside of the chute (24). The neck portion (300) at least partially encloses the inflator (14) and directs inflation fluid into the body portion (330) to inflate the body portion. The neck portion (300) is impermeable to the inflation fluid.

6. An apparatus for protecting a vehicle occupant in the event of a side impact to the vehicle, comprising:
-
an inflatable vehicle occupant restraint having a body portion which is inflatable into a position between the vehicle occupant and a side structure of the vehicle to protect the vehicle occupant; an inflator for inflating said inflatable vehicle occupant restraint; a support member for supporting said inflator and said inflatable restraint on the vehicle; means for securing said inflator and said inflatable restraint to said support member; and a chute connected with said support member for storing said inflatable restraint in said chute and for guiding said inflatable restraint to inflate into a position between the vehicle occupant and the vehicle side structure; said inflatable restraint having a mouth portion connected with said support member at a location outside of said chute; said chute having a tubular configuration including interconnected side walls which define an inlet opening in said chute for receiving inflation fluid from said inflator and which define an outlet opening in said chute opposite from said inlet opening through which said body portion of said inflatable restraint extends when said inflatable restraint is in an inflated condition; said chute walls defining a chute axis which extends at an angle of from about 15°
to about 35°
relative to a front-to-back axis of the vehicle, said chute guiding said inflatable restraint to inflate in a forward direction in the vehicle and at an angle toward the side structure of the vehicle.
