Facial-interface cushion, system, and method for head-mounted displays
View Patent ↗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 the foam layer overlapping at least a portion of a mold channel extending along an arcuate path, the foam layer including a reticulated foam material, (2) forcing the insertion mold member against the foam layer in a direction toward the recessed mold member such that at least a portion of the foam layer is forced into the mold channel toward a channel bottom surface, forming a shaped foam element having a curved surface within the mold channel, (3) heating the shaped foam element to soften the shaped foam element and form the facial-interface cushion, and (4) removing the facial-interface cushion from the mold assembly. Various other facial-interface cushions, systems, and methods for head-mounted displays are also disclosed.
1. A head-mounted-display cushion comprising:
a molded reticulated foam material;
a user-side surface dimensioned to abut a facial portion of a user;
a display-side surface dimensioned to abut a mounting surface of a facial-interface system for a head-mounted display;
a curved surface arcing from the user-side surface toward the display-side surface; and
a cooling channel that:
is formed by a protruding portion of an insertion mold member and that intersects the display-side surface;
extends into the head-mounted display cushion from the display-side surface; and
is dimensioned to allow for movement of air in the head-mounted display cushion in a manner that cools at least a portion of the head-mounted display cushion;
wherein the head-mounted display cushion defines an opening extending through an interior of the head-mounted-display cushion from the user-side surface to the display-side surface.
2. The head-mounted-display cushion of claim 1 , wherein the curved surface defines at least a portion of the opening extending through the interior of the head-mounted-display cushion.
3. The head-mounted-display cushion of claim 2 , further comprising:
an inner side surface defining at least a portion of the opening; and
a sloped surface sloping between the curved surface and the inner side surface.
4. The head-mounted-display cushion of claim 1 , wherein the curved surface is located on at least a portion of an outer periphery of the head-mounted-display cushion.
5. The head-mounted-display cushion of claim 1 , wherein the display-side surface comprises a generally planar surface.
6. The head-mounted-display cushion of claim 1 , wherein a thickness of the head-mounted-display cushion is least in a region shaped to abut a nasal region of the facial portion of the user.
7. The head-mounted-display cushion of claim 1 , wherein the molded reticulated foam material comprises a polyurethane material.
8. A head-mounted-display system comprising:
a head-mounted display; a facial-interface mounting member for the head-mounted display;
a facial-interface cushion abutting the facial-interface mounting member, the facial-interface cushion comprising;
a molded reticulated foam material;
a user-side surface dimensioned to abut a facial portion of a user;
a display-side surface dimensioned to abut the facial-interface mounting member;
a curved surface arcing from the user-side surface toward the display-side surface; and
a cooling channel that: is formed by a protruding portion of an insertion mold member and that intersects the display-side surface;
extends into the facial-interface cushion from the display-side surface; and is dimensioned to allow for movement of air in the facial-interface cushion in a manner that cools at least a portion of the facial-interface cushion;
wherein the facial-interface cushion defines an opening extending through an interior of the facial-interface cushion from the user-side surface to the display-side surface.
