Abstract
The closure device is suitable for use as a lateral door or a back door of a passenger vehicle. It comprises a closure member movable between a closure position on a frame and a fully open position. The linkage connecting the closure member to a body provided with the frame has first arms and second arms. The first arms are pivotally mounted on the body for rotation about a horizontal axis and are pivotally mounted at their other end on a closure member about another axis parallel to the first axis. The second arms each have an end mounted on the body for pivotal movement about a horizontal axis parallel to the other axis and another end pivotally mounted on the closure member for rotation about an axis parallel to the other axis. The second arms are telescopic and have a retracted condition in which they have a first length and an expanded condition in which they have a second length greater than the first length. The second arms are in retracted condition until the amount of pivotal movement of the second arm means from the closed condition of the closing device has exceeded a predetermined extent.
