The motor is drivingly connected to the lower end of the door panel to drive the door panel downwardly in response to actuation of the motor. Preferably, the connection includes a flexible drive element (e.g., an endless belt) driven by the motor and connected to the lower end of the door panel. A pivot member releasably connects the door panel to the guide member, and is pivotable relative to at least one of the door panel or the guide member in response to a force on the door panel. The pivot member includes a first pivot segment pivotally connected to the door panel and a second pivot segment pivotally connected to the guide member, the first and second pivot segments releasably engaging each other.
