Abstract
A cover for use with an air register. The cover includes a base part which extends about the opening through the register and is positioned between the register and the floor. Hinged to the cover base part is a deflector part which extends upwardly over the top of the register so as to cover the register opening when there is no air flow through the register. Upon air flow through the register, deflector part is blown outwardly relative to the register so as to expose the opening in the register.
