<p>The arrangement consists of a frame (1), which is mounted in the vehicle body, with at least one flap which can hinge about a centreline (7.8). The flap is mounted in such a way that the length of the arm, on which the weight of the flap exerts a torque, reduces when the flap opens. The centreline of the hinge of the flaps lies in a vertical plane. The plane (6) in which the flap lies, when closed, makes an angle with the vertical which is less than a equal to 90 deg. This angle gradually reduces while the flap opens. The angle over which the flap can swing is equal to or smaller than 90 deg.</p> |
