Abstract

A cushion assembly for a wearable electronic device includes a polymer structure and foam. The polymer structure can include a laminar portion defining a first aperture and a second aperture, a first tube structure extending from a peripheral edge of the first aperture, and a second tube structure extending from a peripheral edge of the second aperture. The foam can be disposed between the first tube structure and the second tube structure.

First claim

What is claimed is:

1 . A head mountable device, comprising:
a display portion including a display screen; a securement strap connected to the display portion; and a cushion assembly extending from the display portion, the cushion assembly comprising:
a foam layer; and
a perforated polymer barrier including tube structures extending through the foam layer.

2 . The head mountable device of claim 1 , further comprising a textile layer, wherein the perforated polymer barrier is disposed between the textile layer and the foam layer.

3 . The head mountable device of claim 1 , wherein:
the perforated polymer barrier defines a set of apertures; and each tube structure of the tube structures extending through the foam layer extends from an aperture of the set of apertures.

4 . The head mountable device of claim 3 , wherein the perforated polymer barrier is configured to press against a face.

5 . The head mountable device of claim 4 , wherein the tube structures define passageways through the cushion assembly and through which air can flow.

6 . The head mountable device of claim 3 , wherein the apertures of the set of apertures are non-uniformly spaced.

7 . An electronic device, comprising:
a housing defining a contact surface; and a cushion assembly disposed on the contact surface, the cushion assembly comprising:
a polymer structure, including:
a laminar portion defining an aperture;
a tube structure extending from a peripheral edge of the aperture, the tube structure defining a passageway extending through the cushion assembly; and

a foam layer disposed against the laminar portion.

8 . The electronic device of claim 7 , wherein:
the laminar portion is a first laminar portion; and the polymer structure includes a second laminar portion.

9 . The electronic device of claim 8 , wherein the foam layer is disposed between the first laminar portion and the second laminar portion.

10 . The electronic device of claim 9 , wherein:
the aperture is a first aperture; the second laminar portion defines a second aperture; and the tube structure extends from the first aperture to the second aperture.

11 . The electronic device of claim 10 , wherein the second laminar portion defines a third aperture in fluid communication with the foam layer.

12 . The electronic device of claim 11 , wherein:
the tube structure is configured to allow air to pass through the cushion assembly via the first aperture and the second aperture; and the third aperture defined by the second laminar portion, the third aperture defined adjacent to the foam.

13 . A cushion assembly for a wearable electronic device, the cushion assembly comprising:
a polymer structure, comprising:
a laminar portion defining a first aperture and a second aperture;
a first tube structure extending from a peripheral edge of the first aperture; and
a second tube structure extending from a peripheral edge of the second aperture; and
foam disposed between the first tube structure and the second tube structure.

14 . The cushion assembly of claim 13 , wherein:
the first tube structure includes a sidewall having a first surface and a second surface opposing the first surface; the first surface defines an empty conduit of the first tube structure; and the second surface defines an outer surface of the first tube structure in contact with the foam.

15 . The cushion assembly of claim 13 , wherein the foam is disposed against the laminar portion.

16 . The cushion assembly of claim 13 , wherein the polymer structure comprises silicone.

17 . The cushion assembly of claim 13 , wherein a thickness of the foam is substantially equal to a height of the first tube structure.

18 . The cushion assembly of claim 13 , further comprising a third aperture defined by the laminar portion, wherein a first distance separating the first aperture from the second aperture is greater than a second distance separating the second aperture from the third aperture.

19 . The cushion assembly of claim 13 , wherein the polymer structure is molded as a single, unitary piece.

20 . The cushion assembly of claim 13 , wherein the laminar portion is less than about 100 microns thick.
