Abstract
A venting arrangement for an inflatable curtain cushion is disclosed. The inflatable curtain cushion includes a pair of fabric layers that are themselves gas permeable. The fabric layers have an impermeable coating on the interior surface of fabric layers. One or more vents are provided by bonding a portion of the fabric layers together at the impermeable coating. Separation of the bonded fabric layers causes delamination of the coating from one of the fabric layers. Exposure of the underlying permeable fabric allows venting of inflation gas. The bonded fabric layers separate when gas pressure within the inflatable curtain cushion exceeds a threshold pressure. The number and size of the vents can vary depending upon the permeability of the underlying fabric layer and the desired deflation rate.
