A process for producing a motor support device (1), which includes a base (2), a ring (3) extending according to an axis (A) and capable of housing a motor with an axis and at least one decoupling means (4) connecting the base (2) and the ring (3), in which the ring (3) has a first face (5) that extends according to the axis (A) of the ring (3), and the base (2) has a second face (10) that extends according to the axis (A) of the ring (3), the decoupling means (4) being interposed between the first (5) and the second (10) faces with the decoupling means (4) configured to decouple the base (2) from movements of the motor, characterized in that the decoupling means (4) has a six-sided shape including a first side (11) in direct contact with the ring (3), a second side (12) in direct contact with the base (2), and a free third side (13) extending substantially radially relative to the axis (A) of the ring (3) between the first and second sides (11, 12), and in that the third side (13) has at least one recess (15) extending in a direction substantially parallel to the axis (A) of the ring (3), wherein the second face (10) of the base (2) includes ridges (17) extending from the second face (10) toward the ring (3) with the ridges (17) defining a plurality of housings (24) for receiving the second side (12) of a respective one of the decoupling means (4) with each of the housings (24) having a trapezoid shape such that each of the housings (24) get narrow along the axis (A) and the second side (12) of the decoupling means (4) having a trapezoid shape for cooperating with the trapezoid shape of the housings (24) to connect the decoupling means (4) to the base (2), with the base (2), the ring (3) and the decoupling means (4) forming a single part, said process comprising the following steps:
- a) molding in a single molding apparatus the ring (3) and the base (2) with a first plastic material,
- b) over-molding in the single molding apparatus the decoupling means (4) to both the ring (3) and to the base (2) and forming the at least one recess (15) extending in a direction substantially parallel to the axis (A) of the ring (3) in the free third side (13) of the decoupling means (4) with a second plastic material, and
- c) separating the motor support device (1) as a single part from the single molding apparatus.
