Abstract
Abstract In accordance with one aspect of the present invention is a specific, illustrative embodiment of an integrated pump and inflatable liner assembly which comprises a hollow inflatable member for the reception and storage of fluid, the inflatable member having a selected configuration so as to line the protective headgear and partially encircle a user's head; the inflatable member housing at least one resilient member for protection of the user's head; and a pump formed integrally with the inflatable member for moving fluid therein. When the member is positioned inside a helmet, the pump is exposable for adjustment by the user. A bleed valve in the hollow member controls the passage of fluid from the hollow member.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
164 words
An inflatable liner for protective headgear, the liner comprising a hollow member for the reception and storage of fluid, the member having a configuration for lining the protective headgear and partially encircling a user's head, and housing at least one resilient member so as to protect the user's head; means detachable secured to the headgear interior for moving fluid into the member, the moving means being formed integrally with the member and being positioned adjacent to a first hole in the headgear such that the moving means is accessible to the user through the first hole, the first hole being proximate to an ear of the user; and means for controlling the passage of fluid from the hollow member, the control means being formed integrally with the member and being positioned adjacent to a second hole in the headgear such that the control means is accessible to the user through the second hole, the second hole being proximate to an ear of the user.
Claim 2
Dependent Claim
164 words
An inflatable liner for protective headgear, the liner comprising a hollow member for the reception and storage of fluid, the member having a configuration for lining the protective headgear and partially encircling a user's head, and housing at least one resilient member so as to protect the user's head; means detachable secured to the headgear interior for moving fluid into the member, the moving means being formed integrally with the member and being positioned adjacent to a first hole in the headgear such that the moving means is accessible to the user through the first hole, the first hole being proximate to an ear of the user; and means for controlling the passage of fluid from the hollow member, the control means being formed integrally with the member and being positioned adjacent to a second hole in the headgear such that the control means is accessible to the user through the second hole, the second hole being proximate to an ear of the user.
Claim 3
Dependent Claim
21 words
