Mechanism for positioning a movable part relative to a support, between a deployed position where the movable part is at a distance from the support and a retracted configuration where the movable part is located flush with the support, and seafaring vehicle including such a mechanism

Mechanism for positioning a movable part relative to a support, between a deployed position where the movable part is at a distance from the support and a retracted configuration where the movable part is located flush with the support, including:

• a base mechanically attached in a fixed manner to the support and having a central hole;
• a first positioning device, provided with a first body mounted in the central hole of the base and having a first off-centered hole relative to the central hole, and with a first notched wheel mechanically attached to the first body and configured to rotate the first body relative to the base when the first notched wheel is actuated;
• a second positioning device, provided with a second body mounted in the first off centered hole of the first positioning device and having a second off-centered hole relative to the central hole and non-concentric with the first off-centered hole, and with a second notched wheel mechanically attached to the second body and configured to rotate the second body when the second notched wheel is actuated;
• with the first positioning device and the second positioning device which are mounted fixed in translation relative to the base and which are configured to position, along a first direction and along a second direction different from the first direction, an interface member of the movable part which is mounted in the second off-centered hole of the second body of the second positioning device and which is mechanically attached to the positioning mechanism.
