Abstract: Cover systems for vehicles are disclosed. An exemplary vehicle cover comprises a first housing base and a second housing base for mounting on a vehicle, each housing base having at least one channel formed therein. A pulley system is mounted in the first and second housing bases, the pulley system operable to move a cable through the at least one channel formed in each housing base. At least one support bow is mounted on one end to the cable in the at least one channel of the first housing base and mounted on an opposite end to the cable in the at least one channel of the second housing base, the at least one support bow moving between a retracted position and a closed position over the vehicle in response to operation of the pulley system.
