Abstract: A modular retractable door assembly for open-air vehicle and method of articulation during stowage and deployment. The assembly is operable with an open-air vehicle to selectively cover and uncover the passenger side openings of the vehicle with doors and rear panels that pivot and slide inwardly and outwardly to selectively cover passenger side openings in the vehicle, and stow away in a roof enclosure. Two doors and two rear panels hingedly articulate between a deployed position covering the passenger openings; and a stowed position stowed on a pair of stacked rails inside a roof enclosure. The door and rear panel operate independently of each other. Multiple upper hinge members allow the doors and rear panels to pivot about a longitudinal roof support members of the vehicle. The door and rear panels slide in and out of the roof enclosure along traversing roof support members inside the roof enclosure.

Abstract: Mechanically or powered activated, retractable, partition-able enclosure-panels with or without custom brackets for any style open-air-vehicle having roof structures, including cars and boats, is taught. The partition-able enclosure panels for a driver's side, passenger's side, or rear opening of an open-air car, each include two or more partition-sections, and a rotatable spindle, where each of the partition-sections is designed to be attached to and detached from an adjacent partition-section, and each of the partition-sections is fixedly or non-fixedly attachable to the rotating spindle, so that when the partitions are attached to each other and the spindle is rotated all partitions are controlled by said rotating spindle and when the partitions are detached from each other, only the fixedly attached partition is controlled by the rotating spindle providing for deployment or un-deployment of either a panel or a partition-section. A roof or roof-support with built-in panel supporting devices is also taught.

Abstract: Mechanized or motor activated retractable enclosure-panels and custom brackets for any style open-air-vehicle having roof structures, including cars and boats, is taught. Installation takes less than 20 minutes with no drilling required, in most cases. The system includes brackets to directly rotably support the panels. The brackets are bolted directly onto roof supports via preexisting roof-support bolt holes, or onto the track bar that comes with some specialty roofs. A mechanized and/or motorized back-panel completely protects passengers and cargo from the elements using vent flaps for complete corner coverage. Rotational mechanized activators include pull-chains, roller pulleys, and spring-mechanized activators that can be motorized. For vehicles not fitted with a roof structure, a support frame for supporting retractable, mechanized and/or motorized panels is designed. Only a single protective panel is required per vehicle side regardless of vehicle size.
