A side door of a motorized vehicle is provided that includes, but is not limited to a latch mechanism being adapted to cooperate and to engage with a latch member disposed at a door frame. The side door assembly further has an actuator for unlatching the latch mechanism. Further, the latch mechanism and the actuator are mechanical interconnected by a coupling being adapted to transfer an unlatching motion from the actuator to the latch mechanism. Additionally, the side door assembly comprises an impact member that is adapted to at least locally deform the coupling in such a way that the arising deformation counteracts the unlatching motion.
