摘要： Angular motion driving mechanism comprising, mounted on a supporting structure (SUP), a gear wheel (GW) for intermittent rotational movement in clockwise and counter-clockwise directions within an arc bounded by first and second angular positions (a1 and a2, respectively) of the gear wheel (GW) with respect to the supporting structure (SUP), a driving gear (DG) being drivingly coupled to the drive motor (DM) and to the gear wheel (GW) imparting rotational movement to the gear wheel (GW) from said first to said second position (a1 to a2, respectively) in an active mode of the drive motor (DM), a coiled torsion return spring (RS), which is flexed against its bias at rotational movement of the gear wheel (GW) from the first to the second angular position a1 to a2 in the active mode of the drive motor (DM), and which relaxes in the non-active mode of the drive motor (DM) by urging the gear wheel (GW) to return from the second to the first angular position (a2 to a1, respectively). To avoid damaging peak collision impact when stopping the gear wheel in its return swing at its first angular position a1, the angular motion driving mechanism comprises a flexible end stop being constituted by a member (BT1) structurally fixated to the gear wheel (GW) and in said first position a1 engaging with an first embossement (E1) of said supporting structure (SUP), said member (BT1) being flexed at contact collision with said first embossement (E1).
