Abstract

An automotive trim panel assembly including a door inner panel and a plastic interior trim panel are provided wherein central axes of substantially identical pin fasteners and main and auxiliary connector portions are all substantially parallel to one another to provide an easy, simple, less costly assembly process. The interior trim panel includes a plastic main section having inner and outer surfaces, a plastic auxiliary section having inner and outer surfaces and a plurality of hollow main connector portions formed about the periphery of the main section on its inner surface thereof. The interior trim panel also includes a hollow base section formed on the inner surface of the auxiliary section and a hollow auxiliary connector portion formed on the base section and supported above the inner surface of the auxiliary section to avoid a dielock condition and to allow a push pin for the auxiliary “flag” section to be parallel to the other push pins without forming a hole in a side wall portion of the “flag” section. This feature eliminates the use of a Class A—surface-marring screw to secure the flag section to its corresponding portion of the inner panel.

Claims

1. An automotive trim panel assembly comprising:

an inner panel having a plurality of apertures formed therethrough;

an interior trim panel including a plastic main section having inner and outer surfaces;

a plastic auxiliary section having inner and outer surfaces;

a plurality of hollow main connector portions formed about the periphery of the main section on its inner surface thereof;

a hollow base section formed on the inner surface of the auxiliary section; and

a hollow auxiliary connector portion formed on the base section and supported above the inner surface of the auxiliary section; and

a plurality of substantially identical pin fasteners having central axes and received and retained within the main and auxiliary connector portions and the plurality of apertures to fasten the inner and interior trim panels together wherein the central axes of the pin fasteners are all substantially parallel to each other.

2. The assembly as claimed in claim 1 wherein the auxiliary section includes a front wall portion and a side wall portion which extends rearwardly from the front wall portion, the side wall portion having a back edge surface interconnecting the inner and outer surfaces of the auxiliary section and wherein the base section includes an upper support surface for supporting the auxiliary connector portion thereon and wherein the back edge surface is substantially coplanar with the upper support surface.

3. The assembly as claimed in claim 2 wherein the base section includes a base portion having the upper support surface and an inner wall portion connected to the front wall portion and supporting the base portion above the inner surface of the auxiliary section.

4. The assembly as claimed in claim 2 wherein the inner wall portion is a single inner wall portion connected to the side wall portion.

5. The assembly as claimed in claim 1 wherein the outer surface of the auxiliary section is a Class A surface.

6. The assembly as claimed in claim 1 wherein the auxiliary section is a flag-shaped section of the interior trim panel and wherein the assembly is a door trim panel assembly.

7. A plastic automotive interior trim panel for fastening an inner panel thereto, the interior trim panel comprising:

a plastic main section having inner and outer surfaces;

a plastic auxiliary section having inner and outer surfaces;

a plurality of hollow main connector portions formed about the periphery of the main section on its inner surface thereof;

a hollow base section formed on the inner surface of the auxiliary section; and

a hollow auxiliary connector portion formed on the base section and supported above the inner surface of the auxiliary section wherein each of the main and auxiliary connector portions has a central axis substantially parallel to each of the other central axes.

8. A plastic automotive interior trim panel as claimed in claim 7 wherein the auxiliary section includes a front wall portion and a side wall portion which extends rearwardly from the front wall portion, the side wall portion having a back edge surface interconnecting the inner and outer surfaces of the auxiliary section and wherein the base section includes an upper support surface for supporting the auxiliary connector portion thereon and wherein the back edge surface is substantially coplanar with the upper support surface.

9. A plastic automotive interior trim panel as claimed in claim 8 wherein the base section includes a base portion having the upper support surface and an inner wall portion connected to the front wall portion and supporting the base portion above the inner surface of the auxiliary section.

10. A plastic automotive interior trim panel as claimed in claim 9 wherein the inner wall portion is a single inner wall portion connected to the side wall portion.

11. A plastic automotive interior trim panel as claimed in claim 7 wherein the outer surface of the auxiliary section is a Class A surface.

12. A plastic automotive interior trim panel as claimed in claim 8 wherein the auxiliary section is a flag-shaped section of the interior trim panel and wherein the interior trim panel is a door interior trim panel.
