Abstract

An exhaust assembly is provided that includes an exhaust pipe extending rearward from a vehicle into an exhaust passage, and a fascia coupled to the vehicle defining the exhaust passage. The exhaust assembly further includes a bezel defining an exhaust opening substantially aligned with the pipe, and a sleeve configured within the exhaust opening. The sleeve extends rearward to at least the rearmost portion of the exhaust opening and substantially parallel to an exit portion of the pipe. The exhaust opening may further define an exhaust plane tangent to rearmost portion of the bezel, and the sleeve may extend at least to this plane. An upper sleeve may also be configured to extend at least to a line tangent to the rearmost surfaces of an upper bezel and perpendicular to the upper sleeve.

First claim

We claim:

1. An exhaust assembly, comprising:
an exhaust pipe extending rearward from a vehicle into an exhaust passage;
a fascia coupled to the vehicle defining the exhaust passage;
a bezel comprises curved surfaces having a rearmost portion and inner surfaces substantially parallel to an exit portion of the pipe, the bezel defining an exhaust opening substantially aligned with the pipe that comprises an exhaust opening plane tangent to the rearmost portion of the curved surfaces of the bezel, and
a sleeve configured within the exhaust opening,
wherein the sleeve extends tangent to inner surfaces of the bezel and rearward to at least the rearmost portion of the exhaust opening and the exhaust opening plane, and substantially parallel to the exit portion of the pipe.

2. The exhaust assembly according to claim 1 , wherein the sleeve is further configured in a substantially cylindrical shape within the exhaust opening.

3. The exhaust assembly according to claim 1 , wherein the rearmost portion of the sleeve has non-rounded edges.

4. The exhaust assembly according to claim 1 , wherein the sleeve is integral with a heat shield surrounding the exhaust pipe.

5. An exhaust assembly, comprising:
an exhaust pipe with an orifice extending rearward from a vehicle into an exhaust passage;
a fascia coupled to the vehicle defining the exhaust passage;
a bezel defining an exhaust opening substantially aligned with the orifice and comprising an upper and a lower bezel portion having curved surfaces with a rearmost portion that, together, define the exhaust plane that is tangent to the rearmost portion of the curved surfaces of the bezel portions; and
an upper and a lower sleeve configured within the opening,
wherein the sleeves extend rearward to at least the plane and substantially parallel to the orifice, and
further wherein the upper sleeve and upper bezel portion are rearward of the respective lower sleeve and lower bezel portion.

6. The exhaust assembly according to claim 5 , wherein the sleeves define a substantially cylindrical shielded opening.

7. The exhaust assembly according to claim 5 , wherein the rearmost portion of the sleeves have non-rounded edges.

8. The exhaust assembly according to claim 5 , wherein the sleeves are integral with a heat shield surrounding the exhaust pipe.

9. An exhaust assembly, comprising:
an exhaust pipe extending rearward from a vehicle;
a fascia coupled to the vehicle;
an upper and a lower bezel coupled to the fascia defining an exhaust opening; and
an upper and a lower sleeve configured within the opening substantially aligned with the pipe,
wherein the upper sleeve extends rearward to a line that is tangent to the rearmost surface of the upper bezel and perpendicular to the upper sleeve.

10. The exhaust assembly according to claim 9 , wherein the bezels further define an exhaust plane, and further wherein the sleeves extend rearward to at least the exhaust plane.

11. The exhaust assembly according to claim 10 , wherein the upper bezel is rearward of the lower bezel and the upper sleeve is rearward of the lower sleeve.

12. The exhaust assembly according to claim 9 , wherein the ends of the rearmost portion of the sleeves have non-rounded edges.

13. The exhaust assembly according to claim 9 , wherein the sleeves are integral with a heat shield surrounding the exhaust pipe.
