Abstract
Impact resistant retractable safety barriers are disclosed. An apparatus includes a support member, a flexible elongate member to extend and retract through an opening in the support member, and a stop member including a region to interface with the flexible elongate member. The stop member engages with structure of the support member surrounding the opening to limit a distance with which the flexible elongate member extends through the opening. The stop member cooperates with the structure of the support member to maintain a gap between a surface of the region of the stop member and the structure of the support member. A width of the gap is equal to or greater than a thickness of the flexible elongate member.
