Perspiration dissipating support assembly for head-mounted display devices
First Claim
1. A Head-Mounted Display (HMD) device, comprising:
- a housing from which a display protrudes to generate imagery within a field-of-view of a user;
a support assembly to mechanically couple the housing to a head of the user, wherein the support assembly includes at least a vapor-permeable contact layer having an inner surface positioned to contact the head of the user and an outer surface positioned away from the head of the user; and
a vapor-permeable spacer disposed at least partially between the outer surface of the vapor-permeable contact layer and the housing, wherein the vapor-permeable spacer is configured to become at least partially compressed when in contact with the head of the user, by the support assembly, between the housing and the head of the user to maintain a position of the display with respect to the field-of-view of the user.

Abstract
A perspiration dissipating support assembly for head-mounted-display (HMD) devices. Variations of the perspiration dissipating support assembly disclosed herein enable supporting forces for an HMD device to be spread over a large portion of a user'"'"'s head while facilitating dissipation of both liquid perspiration and vapor perspiration via respective dedicated dissipation mechanisms. In some embodiments, the perspiration dissipating support assembly includes a vapor-permeable contact layer that contacts the user'"'"'s head and a vapor-permeable spacer that provides a Moisture Vapor Transmission Rate on the order of several times greater than that of the vapor-permeable contact layer. The vapor-permeable contact layer may have wicking properties that tend to draw perspiration (e.g., via capillary action resulting from a particular technical-weave pattern) away from the user'"'"'s head and into the vapor-permeable spacer through which the perspiration evaporates into the ambient environment. The vapor-permeable spacer may be a three-dimensional fabric and/or an open-cell foam.

9. An apparatus, comprising:
-
a housing that encloses one or more electronic components that generate heat during operation; a display that protrudes downward from the housing to generate imagery within a field-of-view of a user; a support assembly to mechanically couple the housing to a head of the user, wherein the support assembly includes; at least one band for encircling the head of the user; a vapor-permeable wicking layer having an inner surface positioned to contact the head of the user and an outer surface positioned away from the head of the user; and a vapor-permeable spacer disposed at least partially between the outer surface of the vapor-permeable wicking layer and the housing, the vapor-permeable spacer to maintain a position of the display with respect to the field-of-view of the user, wherein the at least one band is configured to generate forces to compress the vapor-permeable spacer against the head of the user. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. An apparatus for securing a wearable electronic device to a user, the apparatus comprising:
-
a housing that encloses one of more electronic components that emit heat during operation; a support assembly to mechanically couple the housing to a body part of the user, wherein the support assembly includes at least a vapor-permeable contact layer having an inner surface positioned to contact the body part of the user and an outer surface positioned away from the body part of the user, and wherein the vapor-permeable contact layer has a first Moisture Vapor Transmission Rate (MVTR); and a vapor-permeable spacer disposed at least partially between the outer surface of the vapor-permeable contact layer and the housing, wherein the vapor-permeable spacer is configured to be at least partially compressed, by the support assembly, between the housing and the body part of the user to maintain a position of the wearable electronic device with respect to the body part of the user, and wherein the vapor-permeable spacer has a second MVTR that is greater that the first MVTR. - View Dependent Claims (19, 20)
