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).

31. The seating assembly of claim 1, wherein the first portion and the second portion are bonded together with an adhesive and are each fabricated from a molded high strength thermoplastic resin selected from styrenics, polyamides, polyolefins, polycarbonates, polyesters or mixtures thereof.

32. The assembly of claim 31, further comprising an external reinforcement panel that is attached over a portion of the seat back.

33. The assembly of claim 31, further comprising upholstery selected from a suitable fabric cover, leather or suede cover, simulated leather or suede cover, or a combination thereof;

a carpet or other floor covering;

or a combination thereof.

34. The assembly of claim 33, further comprising a separately fabricated component that is housed in the open internal spacing.

35. The assembly of claim 1, further comprising an external reinforcement panel that is attached over a portion of the seat back.

36. The assembly of claim 1, further comprising a separately fabricated component that is housed in the open internal spacing.

37. The assembly of claim 36, wherein the separately fabricated component is a motor.

38. The assembly of claim 36, wherein the separately fabricated component is a heating or cooling unit.

39. The assembly of claim 36, wherein the separately fabricated component is an entertainment device.

40. The assembly of claim 36, wherein the separately fabricated component is a communications device.

41. The assembly of claim 36, wherein the separately fabricated component is a global positioning sensor.

42. The assembly of claim 36, wherein the separately fabricated component is selected from transducers, solenoids, sensors, air bag components, lighting, wiring harnesses, pumps, seat belt tensioners, seat belt retractors, seat belt webs, tethers, compass, or a thermometer.

43. The assembly of claim 36, further comprising a sound deadening material between the first and second portions.

44. The assembly of claim 1, wherein the attachment assembly is further adapted to pivotally anchor the seat back directly to at least one body in white portion of said automotive vehicle.

45. The assembly of claim 1, wherein the attachment assembly is adapted to removably anchored the seat back directly to the at least one body in white portion of said automotive vehicle.

46. The assembly of claim 45, further comprising a remote actuator mechanism for removing said attachment assembly from the body in white portion of said automotive vehicle.

13. An automotive vehicle seat back assembly, comprising:

a. a first portion;

b. a second portion formed separately from the first portion but which is joined with the first portion via at least one adhesive joint;
