Vehicle side door assembly
A side door of a motorized vehicle is provided that includes, but is not limited to a latch mechanism adapted to cooperate with a latch member disposed at a door frame, an actuator for locking and/or unlocking the latch mechanism and a coupling means for mechanically coupling (i.e., a mechanical coupling) the actuator and the latch mechanism. A disengagement apparatus is adapted to mechanically disengage the coupling between the actuator and the latch mechanism in response to an external force effect.

4. The side door according to claim 2 , wherein the disassembling member further comprises a protruding portion substantially extending in a cross-vehicle direction, wherein a free end of the protruding portion facing away from the outer door panel is configured to interact with the mechanical coupling.
5. The side door according to claim 1 , wherein the positive lock comprises a semicircular shaped receptacle extending in the cross-vertical direction and a counterpart comprising a semicircular shaped protrusion configured to move slidably in a cross-vehicle direction in the semicircular shaped receptacle.
6. The side door according to claim 1 , wherein the coupling member is configured to transfer forces and to disassemble when a relative force exerted on the first rod portion and second rod portion in a direction transverse to an elongation exceeding a predefined threshold.
7. The side door according to claim 1 , wherein the first rod portion is coupled to the outer door panel and the second rod portion is coupled to an inner door panel.
8. The side door according to any of the claims 1 , wherein the coupling member comprises a first section configured to connect to the first rod portion and further comprises a second section configured to connect to the second rod portion, and a first section and a second section of the coupling member is interconnected with an intermediate section.
9. The side door according to claim 8 , wherein the intermediate section is structurally weakened.
10. The side door according to claim 1 , wherein the positive lock comprises a dovetail coupling with the dove tail slidably connected in the cross-vehicle direction.
11. The side door according to claim 1 , wherein the coupling member comprises a material comprising different shear moduli in each of a transverse and a longitudinal direction.
12. The side door according to claim 1 , wherein the positive lock comprises adhesive that is releasably adhering the first rod portion and the second rod portion.
