Abstract

A vehicle including a door (16) and door frame (14). A hinge mechanism connects the door (16) to the door frame (14), the hinge mechanism including a bracket member (22) having first and second ends (24, 26) and a first support bracket (28) for supporting the first end (24) from a door frame (14) by a pin member (30) and a second support bracket (32) for supporting the second end (26) from a door (16) by a second pin member (34). The invention is characterized by including a hinge latching mechanism (48) for releasably latching one of the first and second ends (24, 26) of the bracket member (22) from pivoting movement relative to the respective one of the first and second support brackets (28, 32).
