Automatic door opening and closing device

摘要

By providing two separate units for actively opening and closing a door of an automobile, safe and reliable door opening and closing operation may be achieved. The first unit is operated to open the door in a normal way and closes the door to its not fully latched state while the second unit completes the door closure operation by closing it to the fully latched state, thereby reducing the unfavorable influences arising from the impact which is otherwise unavoidable for complete closure of the door.
