Abstract
Systems for inflating, and venting inflation gas from, objects are detailed. The systems are especially, although not necessarily, adapted for use with vehicle air bags and allow varying amounts of gas to be evacuated from the bags. The bags may include at least one vent hole through their walls and need only one closure band or membrane per hole.

-
a. providing the inflatable device with (i) a wall having a vent hole therein, the wall defining an interior surface and comprising a normally relaxed area surrounding the vent hole and (ii) a band having a first portion attached to the interior surface of the wall and a second portion aligned with the vent hole so that space exists between the band and the vent hole; and
b. permitting the inflatable device to be tensioned to eliminate the relaxed area and thereby cover the vent hole with the band.
