Abstract
A door check system includes a rod interconnecting a door assembly and a body of a vehicle. The door check system secures the position of the door assembly at any location along a swing path of the door assembly, between a fully open position and a fully closed position. A coil spring is disposed about the rod, with the rod extending through a central aperture thereof. An actuator is coupled to the coil spring and configured for tightening and loosening the coil spring about the rod. When the actuator tightens the spring about the rod, the spring grasps the rod and secures the position of the door assembly relative to the body. When the actuator loosens the spring from about the rod, the door assembly is free to move along the swing path.
