Abstract: An airbag module may include an inflator, a cushion, and a retention apparatus that keeps the cushion in a stowed configuration until deployment. The retention apparatus may include a flexible member wrapped around the cushion and a hook-and-loop fastening strip attached to the flexible member via a sewn seam. The hook-and-loop fastening strip has hooks fastened to the flexible member to secure the flexible member around the cushion. The sewn seam is weak enough to permit the hook-and-loop fastening strip to break away from the flexible member. When the cushion begins to inflate, the sewn seam breaks to allow the hook-and-loop fastening strip to separate from one side of the flexible member while remaining attached to the opposite side. The cushion is able to inflate through the corresponding opening formed in the retention apparatus. In alternative embodiments, the flexible member, fastener, and attachment mechanism may be reconfigured or omitted.
