Claim 12:
13. An inflatable cushion, comprising:
a first film ply extensive in a longitudinal direction and a lateral direction;
a second film ply extensive in the longitudinal direction and the lateral direction and overlaid on and sealed to the first film ply such that the plies define therebetween:
a continuous inflation region extending longitudinally, and
a plurality of chambers extending transversely in fluid communication with the inflation region, wherein each chamber in the plurality of chambers includes an opening to the inflation region which has a configuration to allow fluid flow from the inflation region to each of the plurality of chambers to enable filling of the chambers with fluid injected into the inflation region, while not preventing fluid flow from the plurality of chambers to the inflation region; and

overlapping lines of weakness extend transversely across each of the plies and less than completely across the plies forming a longitudinal strip of connected material substantially excluding the inflation region by terminating approximately as the same location as the plurality of chambers proximate to the inflation region, the lines of weakness being more easily torn than the longitudinal strip of connected material facilitating tearing through the plies to separate portions of the inflatable cushion.
