An overhead door including a door panel vertically movable between a lowered position when the door is closed and a raised position when the door is open, and a motor drivingly connected to a lower end of the door panel to selectively drive the lower end of the door panel downwardly. 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.
