1. A door system comprising:
- a door frame defining an access opening;
a door assembly including a door covering said access opening and having a top edge, a bottom edge and a pair of opposed side edges extending between said top edge and said bottom edge;
a first link having one end pivotally attached at said door assembly top edge adjacent a first one of said door assembly side edges and having an opposite end pivotally attached to said door frame adjacent said door assembly top edge;
a second link having one end pivotally attached at said door assembly bottom edge adjacent said first one of said door assembly side edges and having an opposite end pivotally attached to said door frame adjacent said door assembly bottom edge;
a third link having one end pivotally attached at said door assembly bottom edge and having an opposite end pivotally attached to said door frame whereby said first, second and third links define a path of movement of said door assembly relative to said door frame between a closed position covering said access opening and an open position exposing said access opening, said path of movement being outwardly from said door frame and past a side edge of said access opening; and
a center pillar releasably attached to said door frame at said first one of said door assembly side edges, said first link one end being pivotally secured to a top end of said center pillar and said second link one end being pivotally attached to said door assembly adjacent to a bottom end of said center pillar.

7. A door system for a vehicle comprising:
-
a vehicle door frame defining a front access opening and an adjacent rear access opening;
a center pillar attached to said door frame between said front access opening and said rear access opening;
a door assembly covering said rear access opening and having a top edge, a bottom edge and a pair of opposed side edges extending between said top edge and said bottom edge;
