  • Patent number: 5129677
    Abstract: A cover which covers the top and glassed area of a vehicle and includes hard, impact resistant panels to cover windows of the vehicle against breakage. The cover may be associated with bars which are stowed beneath the doors of the vehicle and which are movable upwardly to a position outwardly of the sides of the vehicle. When in the upper position, the bars protect the sides of the vehicle and prevent the doors from being opened. Controlling the bars are cables which are motor driven. Brackets extend outwardly from the cables to mount the bars. A locking latch may also ride within slits in the door and door jam to prevent the door of the vehicle from being opened when the system is in the operative position. With the protection bars in the up position, the cover may be attached thereto.

  • Patent number: 4530519
    Abstract: A system for protecting the doors and part of the side panels of a stationary vehicle includes a sheet-like shield that is selectively power actuated from a recessed position within the body of the vehicle to an extended position to protect the vehicle's door panels and part of the side panels. The shield, formed of flexible, yet rigid, material, is engaged by a motor-driven spindle mounted within a cylindrical housing. Projecting members, affixed to the inside of the shield, include end portions that are slidably housed within tracks secured to the door frame to provide paths extending from the cylindrical housing (located within the vehicle's rocker panel) so that, upon activating of the motor, the shield is unwound from the spindle and guided to a side covering position.
