Impact resistant retractable safely barriers

An apparatus comprising:

• a support member;
• a first strap to extend and retract through an opening in the support member;
• a second strap;
• and
• a stop member including a region to interface with the first strap, the stop member to engage with structure of the support member surrounding the opening to limit a distance with which the first strap extends through the opening, the stop member to cooperate 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 being equal to or greater than a thickness of the first strap, the stop member elongate along a central axis, the region corresponding to a first inset surface of the stop member positioned between first and second protruding surfaces of the stop member, the first inset surface a first distance from the central axis, the first protruding surface a second distance from the central axis greater than the first distance, the first inset surface to interface with the first strap, the stop member including a second inset surface to interface with the second strap, the stop member including a third protruding surface positioned between the first and second inset surfaces.

An apparatus comprising:

• a support member including spacers surrounding an opening in the support member;
• a flexible elongate member to extend and retract through the opening;
• and
• a stop member including a region having a first surface to interface with the flexible elongate member, the stop member to directly engage a second surface of the support member surrounding the opening to limit a distance with which the flexible elongate member extends through the opening, the stop member to cooperate with the second surface of the support member to maintain a gap between the first surface of the region of the stop member and the second surface of the support member, a width of the gap being equal to or greater than a thickness of the flexible elongate member, the spacers to engage the stop member, the second surface on the spacers, the spacers positioned at locations along the opening spaced apart from the region of the stop member when the stop member is engaging the second surface on the spacers.

An apparatus, comprising:

• a first support member;
• a second support member to be spaced apart from the first support member;
• a panel having a distal end and a proximal end, the panel to extend between the first and second support members when in a blocking position with the proximal end supported by the first support member and the distal end supported by the second support member;
• a stop member to be supported by the panel adjacent the proximal end, the panel including a pliable load bearing material to wrap around and be attached to a first segment of a longitudinal length of the stop member, a second segment of the longitudinal length of the stop member to be urged against a first point of engagement on the first support member in response to a force applied to the panel when in the blocking position, the second segment spaced apart from the first segment, the second segment to be urged against the first point of engagement without the load bearing material being urged against the first support member;
• and
• a bar to be supported by the panel adjacent the distal end, the bar to be urged against a second point of engagement on the second support member, a length of the panel extending between the stop member and the bar being greater than a distance between the first point of engagement and the second point of engagement by less than a thickness of the bar.

An apparatus comprising:

• a support member;
• a roller to be supported by the support member;
• a panel to extend and retract through a slot in the support member, the panel to wrap around the roller when the panel is retracted through the slot;
• and
• a stop member having a dimension larger than the slot such that the stop member cannot pass through the slot, a load bearing material of the panel to be coupled to a first portion of the stop member, a second portion of the stop member to engage the support member at a perimeter of the slot to limit an extent the panel is to extend out through the slot and to maintain a gap between a surface of the first portion of the stop member and the perimeter of the slot, the gap to provide clearance between the stop member and the perimeter of the slot through which the load bearing material is to pass, the stop member to be spaced apart from the roller when the panel is extended through the slot.
