Lift flap mechanism for adjusting a lift flap assigned to an airplane wing by means of a driving system, the lift flap mechanism comprising a main connection mechanism and a secondary connection mechanism in the form of a guide lever disposed in an articulated manner on the lift flap and the flap track, the main connection mechanism having a steering lever arrangement with at least one steering lever which has a first steering lever joint and a second steering lever joint, the at least one steering lever by way of a pendulum coupled to the first steering lever joint being connected with the flap track, and the second steering lever joint being guided such that, by means of a defined angular position of the at least one steering lever, the positions of the main connection joint and of the secondary connection joint are unambiguously determined.

L'invention concerne un mécanisme de volets de sustentation servant à déplacer un volet de sustentation (2) associé au porte-clapet (3) d'une aile portante (1) au moyen d'un système d'entraînement (6). Ce mécanisme de volets de sustentation (4) comprend un mécanisme de raccordement principal (7) et un mécanisme de raccordement secondaire (9) sous forme d'un levier de guidage (40) articulé sur le volet de sustentation (2) et le porte-clapet (3). Le mécanisme de raccordement principal (7) comporte un ensemble levier de commande (20) avec au moins un levier de commande (20a, 20b) pourvu d'une première articulation de levier de commande (24) et d'une deuxième articulation de levier de commande (26). Au moins un levier de commande (20a, 20b) est relié au porte-clapet (3) par l'intermédiaire d'un bras oscillant (25) couplé à la première articulation de levier de commande (24). La deuxième articulation de levier de commande (26) est guidée de telle sorte qu'une position relative déterminée du levier de commande (20a, 20b) détermine clairement les positions de l'articulation du raccordement principal (8) et de l'articulation du raccordement secondaire (42).
