Abstract
A method for manufacturing a facial-interface cushion for a head-mounted display may include (1) positioning a foam layer between a recessed mold member and an insertion mold member of a mold assembly, with a first end portion of the foam layer overlapping a second end portion of the foam layer, (2) forcing the insertion mold member against the foam layer in a direction toward the recessed mold member, thereby forming a shaped foam element including a first end portion that is compressed against a second end portion between the insertion mold member and the recessed mold member, and (3) heating the shaped foam element to form a facial-interface cushion by softening the shaped foam element and bonding the first end portion of the shaped foam element to the second end portion of the shaped foam element. Various other facial-interface cushions, systems, and methods for head-mounted displays are also disclosed.
