Abstract: The present invention is relative to a panel hinged on a receiving part, along at least one curved contour edge, by means of two hinges which define a geometric axis of rotation around which the panel pivots between an open position and a closed position. The panel includes fittings intended to engage, during rotation of the panel between its open and closed positions, with reception fittings carried by the receiving part, in order to press the aforesaid curved edge of the panel against the receiving part, the fittings fixed to the panel describing a curved trajectory the center of which is situated on the axis of rotation around which the panel pivots.
