Abstract
An opening flap comprises a frame and a flap articulated thereto. A lift arm is provided, which is articulated by a principal energy accumulator. A secondary energy accumulator is articulated between the lift arm and the flap. The principal energy accumulator delivers the opening motion of the flap into a position before the dead center thereof. The secondary energy accumulator, which is distinctly weaker, delivers the subsequent opening motion.
