ABSTRACT:
A door system includes a structural member and a door that is movably mounted with respect to the structural member for movement between an open position and a closed position. A spring is mounted with respect to the structural member or the door and being sufficiently positioned to bias the door toward its open position when the door is in its closed position. Active material based actuators may selectively compress the spring prior to door closure to minimize door closing effort.
