Swing trunk lid, for an automobile, has a drive to move it between open and closed positions with the lid weight moving it into a closed position at the bottom of the swing movement and tension to hold it open at the top of the swing

摘要

The trunk lid assembly (1) with a swing trunk lid (4), which pivots at the bodywork (3) of an automobile (2), has a drive system (5) with at least one drive (6) and at least one motor to move the lid between open and closed positions and place the lid under tension when open. At the start of the opening movement (A), the weight of the lid is greater than the tension on it so that it drops into the closed and locked position. At the end (B) of the opening movement, the tension overcomes the lid weight and holds it open. The drive system has two transmissions to control the trunk lid movement through the two stages of the swing action.
