Abstract
An inflatable cushion for a side-impact airbag includes first and second fabric panels forming an expandable chamber. The first fabric panel forms a tubular shape upon inflation and includes a top end and a bottom end having continuous outer perimeters and an inflator aperture. The second fabric panel joined to the top end of the first fabric panel and having a circumference equal to a circumference of the continuous outer perimeter of the top end of the first fabric panel and including a vent aperture. The second fabric panel is orthogonal to a longitudinal axis of the first fabric panel when the inflatable cushion is inflated. The bottom end of the first fabric panel is closed. The longitudinal axis of the tubular-shaped first fabric panel is parallel to a longitudinal axis of a vehicle seat back when the inflatable cushion is deployed.
