Abstract

An exhaust assembly 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, which may define an exhaust plane. The sleeve extends rearward, flush or sub-flush, with the rearmost portion of the exhaust opening or exhaust plane, and substantially parallel to an exit portion of the pipe.

First claim

What is claimed is:

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 comprising 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 the inner surfaces of the bezel and rearward, flush or sub-flush, with a 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 an exhaust plane 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 sleeves extend rearward, flush or sub-flush, with 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 shield within the opening.

7. The exhaust assembly according to claim 5 , wherein the rearmost portion of the sleeves has 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;
upper and lower bezels coupled to the fascia, comprising inner surfaces; and
an upper and a lower sleeve substantially aligned with the pipe, tangentially contacting the inner surfaces,
wherein the upper sleeve extends rearward and sub-flush with a line that is tangent to a 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 and sub-flush with 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 end of the rearmost portion of each of the sleeves has non-rounded edges.

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