A closing device of an opening provided in a structure, comprising a fixed part, wherein an opening is defined, and at least one sliding movable panel guided along two guide rails fitted on one face of the fixed panel, between a closing position, sealing the opening, in a sealing plane defined by the fixed panel, and at least one opening position, in a sliding plane, substantially parallel with the sealing plane, each of the rails bearing at least one shuttle guided in translation in the rail, movable in translation in the guide rails, and switching the movable panel from the sealing position to the at least one sliding position, and slidably moving the movable panel in the sealing plane. According to the invention, at least one of the rails bears, at one of the ends thereof, an end fitting forming a mechanical stop defining a stop position for the shuttle.

A device for closing (1) a bay arranged in a structure comprises a support (7) intended to receive a drive device (8) and to be fixed to said structure. The support (7) comprises a plate (10), intended to be fixed to said structure and receive said drive device (8) and a cover (12), receiving a coupling portion (60) of a transmission means (6) towards the bay. The support (7) is capable of assuming at least one free state, wherein the cover (12) and the plate (10) are free in translation in relation to one another; and a locked state, in which the cover (12) and the plate (10) are immobile in relation to one another.

A hinge for a flap of a motor vehicle includes a flap element which is designed to be secured to the flap. A pivoting element is designed to be secured to a body of the motor vehicle such as to be rotatable about a hinge axis, wherein in a first location the flap element is connected to the pivoting element so as to be rotatable about a rotational axis, and in a second location, which is offset relative to the first location, the flap element is connected to the pivoting element via a releasable securing element. A spacer maintains a distance between the pivoting element and the flap element in an installed position, in which the securing element is released and the flap element is rotated relative to the pivoting element about the rotational axis in comparison to a normal position.
