Various other facial-interface cushions, systems, and methods for head-mounted displays are also disclosed.

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.

Abstract: A head-mounted-display adjustment apparatus may include a strap with a distal section coupled to a distal area of a head-mounted display. The adjustment apparatus may also include a pinion rotatably coupled to a proximal area of the head-mounted display in a manner that holds the head-mounted display against a user's face when a user is wearing the head-mounted display. In addition, the adjustment apparatus may include a rack that is coupled to a proximal section of the strap and includes a plurality of teeth in mesh with the pinion such that (1) rotation of the pinion repositions the rack relative to the head-mounted display and (2) repositioning the rack adjusts an area between the strap and the head-mounted display. Various other head-mounted-display adjustment apparatuses, systems, and methods are also disclosed.

Abstract: Embodiments relate to a metal frame in a head-mounted display (HMD) that is structured to absorb impact and protect components of the HMD. The metal frame has a wall that is spaced away from a protection shell securing a display panel in the HMD. When the HMD is dropped or subject to external force, the wall may deform but keep the protection shell intact. Moreover, the metal frame has protruding ridges and brackets that surround outward facing cameras on the HMD. If the HMD is dropped, the protruding ridges and brackets can provide protection to the cameras.
