Claim 0:
1. 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:
an inflation region extending longitudinally between the plies and being operable to receive a nozzle, and
a plurality of chambers extending transversely from the inflation region, wherein each of the plurality of chambers has an opening to the inflation region which contains no valves therewithin and which has a configuration which allows fluid flow from the inflation region to its respective chamber in the plurality of chambers to enable filling of the chambers with fluid injected into the inflation region from the nozzle, and from the plurality of chambers to the inflation region;

wherein the overlapping plies include a plurality of lines of alternating lands and slits that extend transversely across the plies substantially excluding the inflation region by terminating approximately the same location as transverse seals proximate to the inflation region, with the transverse seals defining the longitudinal sides of the plurality of chambers, the lines of alternating lands and slits being configured to facilitate tearing through the plies to separate portions of the inflatable cushion.
