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.
