A tailgate of modular construction and employing an extender assembly. The tailgate employs a thick central molded plastic core structure and inner and outer cover sheets secured to inboard and outboard faces of the core structure. The core structure defines laterally spaced vertically extending channels and the extender assembly includes a pair of laterally spaced post assemblies slidably mounted in the respective channels of the core member and connected at their upper end by a bar member which fits in a pocket defined in the upper face of the tailgate with the extender assembly in its lowered position.

The invention claimed is: 1. A tailgate module for combination with a tailgate outer panel assembly to form a tailgate, characterized in that: the module includes a thick inner core member and an extender assembly mounted on the inner core member and including an upper lateral structure moveable between a stowed position proximate an upper edge of the inner core member and an extended position spaced from the upper edge, the inner core member defining a pair of laterally spaced vertically extending channels within the core member; the upper lateral structure comprising a bar; and the extender assembly further including a pair of laterally spaced post assemblies secured at their upper ends to laterally spaced points on the bar and respectively slidably received in the channels. 2. A tailgate module according to claim 1 wherein: the inner core member comprises a molded plastic member; the extender assembly is further moveable to a displaced position removed from the plane of the tailgate; each post assembly includes a lower post member articulated to an upper post member connected to the bar; and the axes of articulation are positioned above the upper edge of the main body structure with the bar in its extended position whereby to allow the bar to be moved from its extended position to its displaced position by pivotal movement of the upper post members and the bar about the axes of articulation. 3. A tailgate module according to claim 2 wherein: the module further includes catch means selectively operable to fixedly but releasably secure the bar in its stowed position, in its extended position, and in its displaced position. 4. A module according to claim 3 wherein the catch means comprise coacting catch devices on each post assembly proximate the axis of articulation. 5. A method of forming a tailgate assembly for a motor vehicle comprising the steps of: forming an outer panel member having an inboard face and an outboard face; forming an extender assembly including an upper lateral structure; forming an inner panel member having an inboard face, an outboard face, and a guide structure defined between the inboard and outboard faces; mounting the extender assembly on the inner panel member with guide structure on the extender assembly coacting with the guide structure on the inner panel member to mount the extender assembly on the inner panel for movement between a stowed position in which the upper lateral structure of the extender assembly is proximate an upper edge of the inner panel member and an extended position in which the upper lateral structure is spaced from the upper edge; positioning the inboard face of the outer panel member proximate the outboard face of the inner panel member; and attaching the inner panel member to the outer panel member to define the tailgate assembly having the inner and outer panel members and the extender assembly moveable between the stowed and extended positions relative to the inner and outer panel members. 6. A tailgate comprising: a thick molded inner core member having an outboard face and an inboard face; an inner cover sheet secured to the inboard face of the core member; an outer cover sheet secured to the outboard face of the core member; laterally spaced vertically extending channels defined within the core member; and an extender assembly including a pair of laterally spaced post assemblies slidably positioned respectively in the channels and an upper bar structure interconnecting upper ends of the post assemblies. 7. A tailgate according to claim 6 wherein each post assembly includes a lower post member articulated to an upper post member connected to the bar, the axes of articulation being positioned above an upper edge of the tailgate with the bar in an upwardly extended position, whereby to allow the bar to be moved from its extended position to a displaced position by pivotal movement of the upper post members and the bar about the axes. 8. A tailgate according to claim 7 wherein a multiple position catch structure is defined at the axis of articulation of each post assembly and the tailgate further includes release means operative to release the catch means to allow the bar to be moved from its extended position to its displaced position by pivotal movement of the upper post members and the bar about the axes of articulation. 9. A tailgate according to claim 6 wherein the inner cover sheet includes a main body portion secured to the inboard face of the core member and an upper flange portion extending rearwardly over an upper edge of the core member. 10. A tailgate according to claim 6 wherein the tailgate further includes a molded top cap including a top wall fitted over an upper edge of the core member. 11. A tailgate according to claim 10 wherein the top cap further includes a rear wall extending downwardly proximate the outboard face of the core member. 12. A tailgate according to claim 11 wherein the rear wall of the top cap defines a lower edge fitted against an upper edge of the outer cover sheet. 13. A tailgate according to claim 11 wherein: the top wall of the top cap defines a central pocket; and the bar structure fits in the pocket in a lowered position of the extender assembly. 14. A tailgate according to claim 12 wherein: the outer cover sheet defines a central upwardly opening pocket; and the rear wall includes a central downstanding tongue positioned in the outer cover sheet pocket. 15. A tailgate according to claim 11 wherein the tailgate further includes an extender release assembly including a handle positioned in the rear wall of the top cap for ready access by an operator positioned rearwardly of the tailgate. 16. A tailgate according to claim 9 wherein the inner cover sheet further includes channel sidewalls fitted within the channels defined within the core member. 17. A tailgate according to claim 6 wherein: the tailgate further includes a tailgate release mechanism and an extender release mechanism; and the core member is selectively cut away to accommodate hardware aspects of the tailgate release assembly and the extender release assembly. 18. A tailgate according to claim 17 wherein the core member has a molded honeycomb construction. 19. A tailgate according to claim 8 wherein the release means includes horizontal members extending laterally from the upper post members and operative in response to vertical movement thereof to release the catch means.
