Abstract

A vehicle seat in accordance with an exemplary embodiment is provided. The vehicle seat includes an air bag module coupled to a vehicle seat frame, the air bag module having an inflatable cushion. The vehicle seat further includes a seat cover configured to cover at least a portion of the air bag module. The seat cover has a deployment opening defining a first edge and a second edge adjacent the first edge. The vehicle seat further includes first and second interlocking members attached to the seat cover proximate the first and second edges, respectively. The first interlocking member is configured to interlock with the second interlocking member to thereby close the deployment opening. The first and second interlocking members extend substantially an entire length of the first and second edges. The first and second interlocking members disengage from one another upon deployment of the inflatable cushion to allow the inflatable cushion to pass through the deployment opening.
