Abstract

An improved seating system that includes a seat back assembly (10) that is fabricated to include a seat back (12) with a first panel portion (14) that is optionally secured to a second panel portion (16) with one or more fasteners such as welds, adhesives, tack-offs, steel brackets or otherwise. The first panel portion (14), the second panel portion (16) or both preferably are plastic. The seat back assembly (10) may include one or more integrated reinforcement structures (20).

Claims

1. An instrument panel assembly for an automotive vehicle, comprising:

a first molded plastic panel, the first plastic panel formed of a first plastic material; and

a second molded plastic panel joined to the first panel, the second plastic panel formed of a second plastic material different from the first plastic material wherein;

i. the first molded plastic panel, the second molded plastic panel or both extend cross-vehicle;

ii. at least one of the first plastic material and the second plastic is formed of a polyolefin material;

iii. at least one of the first or second panels assists in defining an air duct for a vehicle cabin heating and cooling system; and

iv. the first panel is joined to the second panel with one or more mechanical joints; and

wherein the first panel includes a first flange that extends along a length and side of the first panel, the second panel includes a first flange that extends along a length and side of the second panel, and the first panel and second panel are joined to each other at the first flange of the first panel and the first flange of second panel and wherein the first flange of first panel opposes and is coextensive with the first flange of the second panel and wherein the first flange of the first panel and the first flange of the second panel cooperatively extend away from the air duct.

2. An assembly as in claim 1 wherein the one or more mechanical joints include one or more mechanical interlocks.

3. An assembly as in claim 1 wherein at least one of the panels provides a vent that is configured to open into a passenger compartment of the vehicle.

4. An assembly as in claim 1 wherein the first material is from a different plastic family than the second material.

5. An assembly as in claim 1 wherein the first panel and the second panel are joined to a show surface that is exposed to view in an automotive vehicle.

6. An assembly as in claim 5 wherein the show surface is molded-in-color thermoplastic.

7. An assembly as in claim 1 wherein the first panel includes a second flange that extends along a length and side of the first panel, the second panel includes a second flange that extends along a length and side of the second panel, and the first panel and second panel are joined to each other at the second flange of the first panel and the second flange of the second panel.

8. An assembly as in claim 1 wherein the first material or the second material consists essentially of polypropylene and the first material or the second material consists essentially of pc/abs.

9. An instrument panel assembly for an automotive vehicle, comprising:

a first molded plastic panel, the first plastic panel formed of a first plastic material; and

a second molded plastic panel joined to the first panel, the second plastic panel formed of a second plastic material different from the first plastic material wherein;

i. the first molded plastic panel, the second molded plastic panel or both extend cross-vehicle;

ii. the first material or the second material includes polypropylene and the first material or the second material includes pc/abs; and

iii. the first panel is joined to the second panel with one or more mechanical joints that form a mechanical interlock;

wherein one or both of the first panel and the second panel include an opening for receiving an instrument or a gauge; and

wherein the first panel includes a first flange that extends along a length and side of the first panel, the second panel includes a first flange that extends along a length and side of the second panel, and the first panel and second panel are joined to each other at the first flange of the first panel and the first flange of second panel and wherein the first flange of the first panel opposes and is coextensive with the first flange of the second panel and wherein the first flange of the first panel and the first flange of the second panel cooperatively extend away from the air duct.

10. An assembly as in claim 9 wherein the one or more mechanical joints include one or more mechanical interlocks and the mechanical interlocks include a protrusion received in a channel.

11. An assembly as in claim 9 wherein at least one of the panels provides a vent that is configured to open into a passenger compartment of the vehicle.

12. An assembly as in claim 9 wherein the first material is from a different plastic family than the second material.

13. An assembly as in claim 9 wherein the first panel and the second panel are joined to a separate show surface that is formed of a molded-in-color thermoplastic polyolefin.

14. An assembly as in claim 13 wherein the show surface is exposed to view in an automotive vehicle.

15. An assembly as in claim 9 wherein one or both of the first panel and the second panel include an opening for receiving a gauge.

16. An assembly as in claim 9 wherein one or both of the first panel and the second panel include an opening for receiving an instrument.

17. An assembly as in claim 9 wherein the first panel includes a second flange that extends along a length and side of the first panel, the second panel includes a second flange that extends along a length and side of the second panel, and the first panel and second panel are joined to each other at the second flange of the first panel and the second flange of the second panel.

18. An assembly as in claim 9 wherein the first panel and second panel are adapted to be joined to a separate show surface of the vehicle.

19. An instrument panel assembly for an automotive vehicle, comprising:

a first molded plastic panel, the first plastic panel formed of a first plastic material; and

a second molded plastic panel joined to the first panel, the second plastic panel formed of a second plastic material different from the first plastic material wherein;

i. the first molded plastic panel, the second molded plastic panel or both extend cross-vehicle;

ii. the first material or the second material consists essentially of polypropylene and the first material or the second material consists essentially of pc/abs;

iii. at least one of the first or second panels assists in defining an air duct for a vehicle cabin heating and cooling system; and

iv. the first panel is joined to the second panel with one or more mechanical joints that form a mechanical interlock;

wherein the first panel and second panel are separate from a show surface of the vehicle;

wherein one or both of the first panel and the second panel include at least one opening for receiving an instrument or a gauge; and
