Automotive vehicle instrument panel system
View Patent ↗An instrument panel system includes box sections that increase the stiffness, rigidity, and natural frequency of the instrument panel system. A two-piece instrument panel system provides a two-tone appearance with differing die draws and grains.
1. A vehicle instrument panel system comprising:
an upper substrate;
a lower substrate having a rear edge portion and a portion configured to be covered by the upper substrate, wherein the portion configured to be covered by the upper substrate includes a plurality of forwardly located corrugations and wherein portions of two adjacent corrugations and a portion of the upper substrate form a closed structural section; and
a cross car beam assembly configured to support the lower substrate and attached with the lower substrate in a vicinity of the rear edge portion of the lower substrate such that the lower substrate and cross car beam assembly form a closed structural member.
2. The system of claim 1 wherein the upper substrate has a first color and wherein the lower substrate has a second color different than the first color.
3. The system of claim 1 wherein the upper substrate has a first die draw and the lower substrate has a second die draw different than the first die draw.
4. The system of claim 1 wherein the upper substrate has a first grain and the lower substrate has a second grain different than the first grain.
5. The system of claim 1 wherein each of the plurality of corrugations has a top and wherein the upper substrate is bonded with each of the tops.
6. The system of claim 5 wherein the upper substrate is ultrasonically bonded with each of the tops.
7. The system of claim 5 wherein the upper substrate is vibration welded with each of the tops.
8. The system of claim 5 wherein the upper substrate is heat staked with each of the tops.
9. The system of claim 5 wherein the upper substrate is chemically adhered with each of the tops.
10. A vehicle instrument panel system comprising:
a substrate having a rear edge portion and a corrugated portion having a plurality of forwardly located corrugations;
a topper configured to cover the corrugated portion, portions of two adjacent corrugations and a portion of the topper forming a closed structural member; and
a cross car beam assembly attached with the rear edge portion such that the substrate and cross car beam assembly form a closed structural member.
11. The system of claim 10 wherein the substrate has a first color and wherein the topper has a second color different than the first color.
12. The system of claim 10 wherein the substrate has a first die draw and the topper has a second die draw different than the first die draw.
13. The system of claim 10 wherein the substrate has a first grain and the topper has a second grain different than the first grain.
14. The system of claim 10 wherein each of the plurality of corrugations has a top and wherein the topper is bonded with each of the tops.
15. An instrument panel system for a vehicle including a body structure for supporting the instrument panel system, a climate control unit, and a windshield, the system comprising:
a cross car beam assembly for supporting a substrate assembly mechanically attached with the body structure;
a defroster air duct mechanically attached with the cross car beam assembly for guiding air from the climate control unit to the windshield; and
a substrate assembly mechanically attached with the cross car beam assembly and fixed to the defroster air duct wherein the cross car beam assembly, defroster air duct, and substrate assembly form a closed structural member.
16. The system of claim 15 wherein the cross car beam is bolted with the body structure.
17. The system of claim 15 wherein the cross car beam is screwed with the body structure.
18. The system of claim 15 wherein the cross car beam assembly and substrate assembly form a closed structural member.
