Vibration damper device comprising a flange ring capable of coming to a stop against a damper unit

A damping device for installing a support plate of a windscreen-wiper mechanism on a structure element, comprising:

• a cylindrical damper unit with a vertical main axis pierced by a central bore for the passage of an element for mounting the damper unit on the structure element,
• wherein the damper unit comprises a top radial flange and a bottom radial flange, both of which are cylindrical and accommodated on one side by a horizontal plate of the plate and which define between them an inner radial groove wherein the edge of an orifice that complements the plate is accommodated so as to ensure that the damper unit is supported with regard to the plate in the axial direction, and
• wherein the plate comprises at least one cylindrical vertical flange supported by the horizontal plate which extends opposite the outer cylindrical surface of an associated flange,
• wherein the flange ring comprises a concave inner cylindrical surface which is capable of resting radially against a convex outer cylindrical surface of the flange, in at least one overall horizontal direction;
• and
• at least one stop element arranged between the concave inner cylindrical surface of the flange ring and the convex outer cylindrical surface of the flange, which is capable of resting simultaneously against the concave inner cylindrical surface of the flange ring and the convex outer cylindrical surface of the flange.
