The pivoting system (2) is adapted for arranging the cover plate (1) in a first end position (P1) or in a second end position (P2) in response to an internal force (FI), or an internal force (FI) and an external force (FE), being applied onto the cover plate (1). The cover plate (1) is arranged in the first end position (P1) when force FE≤FI and in the second end position (P2) when force FE>FI. The present invention further relates to a method of operating such a system.
