    • Abstract:
      An air flow control device for a front face module of a motor vehicle, the control device including a frame and a plurality of vanes extending within and attached thereto in a rotatable manner, each vane being rotatable about an axis of rotation substantially parallel to the main extension direction of each vane. The vanes being able to rotate between an open position and a closed position. The frame includes an integral support bar extending in direction perpendicular to the main extension direction of the vanes, with the vanes having fins configured to rest on the support bar when the vanes are closed and pressured towards the support bar.

    • Claim:
      1. An air flow control device for a front face module of a motor vehicle, said control device comprising: a frame, with the frame including an integral support bar; and a plurality of vanes, the plurality of vanes extending within the frame and being attached thereto in a rotatable manner, each vane being rotatable about an axis of rotation substantially parallel to a main extension direction of each vane, the vanes being able to rotate between an open position and a closed position, with the integral support bar extending in a direction perpendicular to the main extension direction of the vanes, wherein each of the plurality of vanes has a fin configured to rest on the integral support bar when the vane is closed and pressured towards the integral support bar, wherein the fins protrude from the vanes for a distance corresponding to the distance between vanes in the open positions.
    • Claim:
      2. The control device of claim 1 , wherein the frame includes a support protrusion at one end of the integral support bar protruding towards the closest vane so that it substantially abuts it in its open position.
    • Claim:
      3. The control device of claim 1 , wherein the frame includes a support groove at one end of the integral support bar configured to receive a fin of the closest vane.
    • Claim:
      4. The control device of claim 1 , wherein the integral support bar has a guiding groove extending along its length to receive fins in the open position, in the closed position and all the intermediate angular positions.
    • Claim:
      5. The control device of claim 4 , wherein the support bar includes quarter-circle cutouts in which the vanes in the closed position are received and supported, the cutouts being shaped to guide the movement of the vanes towards the open position.
    • Claim:
      6. The control device of claim 1 , wherein the support bar is perforated.
    • Claim:
      7. The control device of claim 1 , wherein the fins have substantially triangular shapes.
    • Claim:
      8. The control device of claim 1 , wherein the fins have substantially semicircular shapes.
    • Claim:
      9. The control device of claim 1 , wherein the edges of the fins include a vibration damping material.
    • Claim:
      10. The control device of claim 1 , wherein the control device includes a plurality of support bars, and the vanes include a plurality of respective fins adapted to operate with the plurality of support bars.
