Adjustable strap assemblies, systems, and methods for head-mounted displays

A head-mounted-display system comprising:

• a head-mounted-display device;
• and
• a first lateral strap member configured to extend along a first side and a back of a user's head;
• a second lateral strap member configured to extend along a second side and the back of the user's head, the first and second lateral strap members each comprising:
• a proximal portion coupled to the head-mounted-display device;
• a distal end disposed away from the proximal portion;
• and
• a first and second arcuate biasing sections that arcs from the proximal portion to the distal end of the first and second lateral strap members, the first and second arcuate biasing sections comprising a resilient material, wherein:
• the first and second arcuate biasing sections peripherally surround at least a portion of a reduced region when the first and second arcuate biasing sections are in a relaxed state;
• the first and second arcuate biasing sections are automatically tensioned by the resilient material and deflected outward by the user's head when the head-mounted-display system is worn by the user such that the first and second arcuate biasing sections peripherally surround at least a portion of an increased region that is greater in size than the reduced region and such that at least a portion of the first and second arcuate biasing sections are biased toward the user's head;
• and
• the first and second arcuate biasing sections maintain contact between overlapping portions of the first and second arcuate biasing sections.

A method comprising:

• coupling a head-mounted-display device to a first lateral strap member configured to extend along a first side and a back of a user's head;

• a proximal portion coupled to the head-mounted-display device;
• a distal end disposed away from the proximal portion;
• and
• a first and second arcuate biasing sections that arcs from the proximal portion to the distal end of the first and second lateral strap members, the first and second arcuate biasing sections comprising a resilient material, wherein:
