ABSTRACT:
A permanently mounted vehicle shade draws a blind across an aperture that is formed by the vehicle chassis, in order to shade the vehicle interior. To do this, a pair of hollow guide tracks are mounted on the chassis opposite the aperture from each other. For each guide track, a carriage is threaded onto a drive screw, and the drive screw is coaxially mounted for rotation within the hollow of the track. Each guide track also has a longitudinal slot, and each end of the rod is inserted into a respective slot and attached to a respective carriage. This positions the rod across the aperture. Next, a supply roller is permanently mounted on the vehicle chassis parallel to the rod. One end of the blind is attached to the rod, and the other end is attached to the supply roller. For operation, the drive screws are selectively rotated in unison. The rotation of the drive screws is converted into translational motion of the carriages, to move the attached rod and draw the blind across the aperture.
