What is claimed is: 1. A seating assembly for an automotive vehicle, comprising: a plastic seat back having at least one wall portion having a forward wall portion and a rearward wall portion, the forward wall portion and rearward wall portion defining an interior open space between them; a tubular shaped reinforcement insert substantially enclosed by the forward wall portion, the rearward wall portion or a combination of both, wherein; i) the reinforcement insert extends about perimeter regions of the seat back; ii) the reinforcement insert intimately contacts a substantial portion of at least the forward wall portion or the rearward wall portion; and iii) the reinforcement insert is formed of a metal selected from steel, titanium, magnesium, aluminum or a combination thereof; and a plurality of integrally molded plastic reinforcement structures extending across at least a portion of the at least one wall portion and forming a shaped pattern on the seat back; wherein the seat back is pivotal within the automotive vehicle. 2. A seating assembly as in claim 1 further comprising a hinge assembly securing the at least one wall portion to the vehicle wherein the reinforcement insert is in the vicinity of the hinge bracket. 3. A seating assembly as in claim 1 wherein the reinforcement insert is hollow. 4. A seating assembly as in claim 1 wherein said seating assembly is capable of withstanding, without rupture, at least about 13000 Newtons in a direction in which said seat faces in a plane, parallel to the longitudinal centerline of said vehicle, and exhibits, upon rapid acceleration up to about 20 to about 30 g, no fragmentation of said seat back with at least a 30 kg mass placed behind said seat back. 5. A seating assembly as in claim 1 wherein the reinforcement insert is located between the forward wall portion and rearward wall portion. 6. A seating assembly as in claim 1 wherein the reinforcement insert is located within about 50 mm of an edge defining a perimeter of the seat back. 7. A seating assembly for an automotive vehicle, comprising: a plastic seat back having a forward wall portion and a rearward wall portion with an interior open space therebetween wherein: i) the seat back is pivotal within the automotive vehicle; ii) the forward wall portion and the rearward wall portion both include an internal and an external surface; and a reinforcement insert disposed within a cavity defined in a surface of at least one of the forward wall portion or the rearward wall portion wherein; i) the reinforcement insert is formed of a metal selected from steel, titanium, magnesium, aluminum or a combination thereof; ii) the reinforcement insert is located adjacent a peripheral edge of the seat back and is coextensive with the edge of the seat back. 8. A seating assembly as in claim 7 wherein the forward wall portion, the rearward wall portion or both substantially surround the insert. 9. A seating assembly as in claim 8 wherein the forward wall portion and the rearward wall portion are formed of a blow molded plastic or an injection molded plastic. 10. A seating assembly as in claim 8 wherein the forward wall portion and the rearward wall portion or both contact a substantial portion of the reinforcement insert. 11. A seating assembly as in claim 8 wherein the reinforcement insert is located within about 50 mm of an edge defining a perimeter of the seat back. 12. A seating assembly as in claim 8 wherein the forward wall portion and rearward wall portion are formed a thermoplastic that includes a polycarbonate material, a styrenic material, a polyester, a polyamide, a polyolefin or a combination thereof. 13. A seating assembly as in claim 7 further comprising a hinge assembly securing the forward and rearward portions to the vehicle wherein the reinforcement insert is in the vicinity of the hinge bracket. 14. A seating assembly as in claim 7 wherein the reinforcement insert is hollow, has a rounded shape or both. 15. A seating assembly as in claim 7 wherein said seating assembly is capable of withstanding, without rupture, at least about 13000 Newtons in a direction in which said seat faces in a plane, parallel to the longitudinal centerline of said vehicle, and exhibits, upon rapid acceleration up to about 20 to about 30 g, no fragmentation of said seat back with at least a 30 kg mass placed behind said seat back. 16. A seating assembly as in claim 7 wherein at least one integrally molded plastic reinforcement extends across at least a portion of the forward wall portion, the rearward wall portion or both. 17. A seating assembly for an automotive vehicle, comprising: a plastic seat back having a forward wall portion and a rearward wall portion with an interior open space therebetween wherein: i) the seat back is pivotal within the automotive vehicle; ii) the forward wall portion and the rearward wall portion both include an internal and an external surface; and iii) the seat back defines a cavity within the external surface of at least one of the forward wall portion and the rearward wall portion; a reinforcement insert disposed within the cavity defined in the external surface wherein; i) the reinforcement insert is hollow and is formed of a metal selected from steel, titanium, magnesium, aluminum or a combination thereof; ii) the reinforcement insert is rounded in shape; iii) the reinforcement insert is located adjacent a peripheral edge of the seat back and is coextensive with the edge of the seat back; and iv) the at least one of the forward wall portion and the rearward wall portion contact a substantial portion of an outer surface of the reinforcement insert; and v) at least one integrally molded plastic reinforcement extends across at least a portion of the forward wall portion, the rearward wall portion or both.
