Abstract
A suspension device for a lowerable luggage stowage compartment has at least one spring element for assisting the movement of the compartment into a closed position against the force of gravity, and at least one damping element for damping the movement of the compartment into an opened position. A weight detector detects the weight of the compartment, and at least one additional spring element can be actuated based on the detected weight of the compartment. A retention device is provided for fixing the additional spring element. The suspension device provides a compartment that is easy to handle and easy to close even when fully loaded.
