Abstract

A vehicle includes a supplemental tailgate assembly, which includes a tailgate extender that retracts within the tailgate and is extendable therefrom and right and left hand gate assemblies. The supplemental tailgate assembly is able to provide bed extender, box extender, step assist, roof rack, cargo storage area, and box divider functions. The supplemental tailgate assembly is stowable to minimize interference in cargo space when not in use.

6. The tailgate assembly of claim 2 wherein the first gate assembly includes a fifth gate that is hingedly mounted between the first gate and the second gate, and the second gate assembly includes a sixth gate that is hingedly mounted between the third gate and the fourth gate.

7. The tailgate assembly of claim 1 wherein the first gate assembly includes a third gate that is hingedly mounted between the first gate and the second gate.

8. The tailgate assembly of claim 1 further including a step assist stop, and wherein the guide system includes a pivot support and the telescoping support includes a pivoter that cooperates with the pivot support to allow the telescoping support to rotate downward into engagement with the step assist stop when the telescoping support is substantially fully extended from the guide system and the tailgate is oriented in the generally horizontal open position.

9. The tailgate assembly of claim 8 wherein the first gate assembly includes a step assist handle mounted thereto.

10. The tailgate assembly of claim 8 wherein the cross member includes a flip step pivotally mounted on cross member.

11. The tailgate assembly of claim 1 wherein the movable frame assembly includes a latching assembly that selectively latches the movable frame portion in a retracted position in the guide system, and a latch release that operatively engages the latching assembly to selectively release the movable frame portion from the retracted position in the guide system.

12. The tailgate assembly of claim 1 wherein the first gate assembly includes hinge plate adapted to pivotally couple between the first gate and the first side wall, the hinge plate includes a tongue extending therefrom, and the first gate includes a groove slidably connected to the tongue.

13. The tailgate assembly of claim 1 wherein the tailgate frame includes a top portion, and the telescoping support is retractable within the guide system such that the cross member is substantially flush with the top portion.

14. The tailgate assembly of claim 1 wherein first gate assembly has a stowed position where the second gate is pivotable relative to the first gate so that the second gate extends substantially parallel to the first gate, and the first gate is adapted to be pivotable relative to the first side wall so that the first gate extends substantially parallel to the first side wall.

15. The tailgate assembly of claim 1 wherein the first gate assembly includes a third gate that is hingedly mounted between the first gate and the second gate, and the first gate assembly has a storage area position where the first gate and the second gate are adapted to extend generally normal to the first side wall, with the second gate having an edge that is adapted to be adjacent to the first side wall.

16. A tailgate assembly for use with a motor vehicle having a first generally vertical side wall and a second generally vertical side wall, spaced from the first side wall, and a generally horizontal bed extending therebetween, the tailgate assembly comprising:

a tailgate frame defining a generally hollow cavity therein and adapted to pivotally mount generally between the first and second side walls and being operable in a generally horizontal open position and generally vertical closed position;

a tailgate extender having a guide system secured generally within the hollow cavity, and a movable frame assembly having a support member extendable from, pivotable relative to, and retained by the guide system, and a cross member connected to the support member and extending generally normal thereto, the support member being pivotable into an upwardly extending position and a downwardly extending position when the tailgate frame is in the horizontal open position; and

the guide system including a pivot support apparatus cooperable with pivot pins carried on the support member to permit pivotal movement of the support member relative to the guide system, said pivot pins being positioned at a distal end of the support member spaced from the cross member and extending outwardly from opposing sides of said support member, the pivot support apparatus including a pivot bracket mounted on opposing sides of the guide system so that the outwardly extending pivot pins can pivotally engage each respective pivot bracket.

17. The tailgate assembly of claim 16 wherein the tailgate frame includes a stop member engagable with the support member when the frame assembly is positioned in the downwardly extending position with the tailgate frame being in the horizontal open position.
