  • Patent number: 4695089
    Abstract: An open-top vehicle body structure including a foldable hood and a linkage for extending and folding the hood. At each side, a reversible motor is provided for actuating the linkage. In order to synchronize the operation of the motors at the respective sides, a connecting rod or flexible shaft is provided and connects together the output shafts of the motor. The linkage includes a swingable pillar of an inverted U-shape having opposite leg portions mounted on the body section for swinging movement about a transverse extending horizontal axis. The hood is connected at a front edge portion to the swingable pillar and at a rear edge portion to a part of the body located rearwardly of the swingable pillar. A rigid roof panel is removably mounted between a swingable pillar and a front windshield. The rotation of the motors produces a swingable movement of the pillar.
