Joint-door hinge

A hinge arrangement for a first door of a pair of opposing hinged doors comprises a curved extension, a first pivotal connection which connects the bent extension, and a body of the vehicle to one another, and a second pivotal connection which connects the bent extension and the first door to each other. Upon opening of the first door, a first edge of the first door about the first pivot connection of the body pivots away and draws a second edge of the door of an adjacent second door away. The first door pivots about the second pivot connection, to open the first door independently of the adjacent second door.
