Two-part grommet
First Claim
1. A snap-in grommet assembly for installation in an automotive bodywork aperture comprising:
- a first relatively flexible component having an elongate conduit portion and an integral bell-shaped portion of a diameter which is greater than the diameter of the conduit portion and which has an open mouth, the bell-shaped portion having an annular retainer portion defined by parallel spaced first and second annular walls defining an interior annular retainer volume therebetween; and
a second relatively stiff component comprising an annular exterior flange sized to fit complementally into the annular retainer volume, and a smaller diameter locking portion for snapping into the bodywork aperture, the locking portion extending axially from the flange therefrom so as to extend through the open mouth and be external of the bell-shaped portion when the flange is installed in the retainer volume;
said flange and at least one of the annular walls defining said volume having complemental retention elements formed therewith to secure the second component within the first component.

Abstract
A two-part grommet assembly for routing wiring and/or washer fluid conduit through an aperture in automotive bodywork to a spoiler mounted CHMSL/rear window washer. The grommet assembly includes a first soft pliable component having a tubular portion and a bell-shaped portion, the latter being configured to provide an interior annular volume to receive the external flange of a second component made of a relatively stiff material. The second component is configured to snap into the aperture in the automotive bodywork to mount the grommet on the exterior of the vehicle and/or within a spoiler assembly. Complemental retention structure is provided within the annular retainer volume which receives the flange of the snap lock component and compression of the materials during installation enhances the retention function.

9. An automotive lighting assembly comprising:
-
a first bodywork component having an aperture formed therein and a second bodywork component disposed on the first bodywork component over said aperture and including a lighting fixture having wiring;
a snap-in grommet assembly for installation in said aperture for routing said wiring through said aperture, said grommet assembly comprising;
a first relatively flexible component having an elongate conduit portion and an integral bell-shaped portion of a diameter which is greater than the diameter of the conduit portion and which has an open mouth, a seal skirt around the mouth and an annular retainer portion defined by parallel spaced first and second walls defining an interior annular retainer volume therebetween; and
a second relatively stiff component comprising an exterior annular flange sized to fit complementally into the annular retainer volume, and a locking portion extending axially therefrom so as to be external of the bell-shaped portion when installed therein;
said flange and at least one wall defining said volume having complemental retention elements formed therewith to secure the second component within the first component. - View Dependent Claims (10, 11)
