This allows a user to always have contact with the handle at all angles of rotation of the covering. The rotation is accomplished through a direct drive or a gearing system which in this case could be in the form of a miter gear, or other bevel gears linking two shafts together. Other embodiments are also possible such as drive mechanisms associated with a push plate, cables and pulleys, or gear boxes.

Abstract: An automated car door opening system proposes a very simple yet reliable system that can easily be retrofitted on most cars. It uses the combination of a large electrically actuated inner shaft cooperating with a piston. The piston opens the car door slightly in a manner similar to the normal opening of a car door, so that the door clears the car frame and then, a combination of outward but more predominantly upward motion by the inner shaft has the door opening in an upwardly rotational motion along a vertical plane which fully opens it. The reverse process closes the door.
