Abstract: A window safety system having a first and second vertical track installed as mirror images on opposite sides of a window frame. The system utilizes at least one elongate blocking element which extends across the window width and is secured to opposing guide elements which smoothly travel within the vertical tracks. A system cover is engaged at opposite ends to guide elements which travel in the vertical tracks. The guide elements are connected in series to one another by a flexible belt within the vertical tracks. The system cover interacts with a lower rail of a window sash such that when the window sash is raised to an open position, the system cover travels with the lower sash. This travel in turn causes the guide elements to translate within the vertical tracks and guiding blocking rods to a position laterally across the opening of the window. The blocking rods thereby prevent egress of a child or the like through the open window.

Hinge lever assemblies attached to the door and guard in the forward area cause it to shift and interlock and disengage both vertical casing members when encountering stop plates on forward casing receptacles.

Abstract: The door inner and outer panels are detachably attached to one another to permit separation to access the space therebetween containing the door hardware. A device mounts the door inner panel and the door outer panel on the vehicle body for independent hinging movement so that the panels move between door open and door closed position in unison with one another when the panels are attached, and the detachment of the panels from one another permits the outer panel to swing away from the inner panel to provide unobstructed access to the door hardware mounted in the space between the panels. The inner and outer panels may be constructed of molded plastic and with one panel having a receptacle receiving the door guard beam and the other panel having an integral molded structure receiving the receptacle upon attachment of the panels together so that the door guard beam becomes effectively coupled with both of the panels.

Abstract: An automobile body is provided with a transparent roof panel that slides rearwardly from a normal position in which it closes a roof opening of the body, to a retracted position in which it overlies a rear window of the body. A sunshade mounted below the transparent roof panel is automatically slid rearwardly into a stowed position adjacent a roll bar separating the roof opening and the rear window when the transparent roof is moved to its retracted position. When the transparent roof is in its normal position in which it closes the roof opening, the sunshade may be manually slid back and forth to overlap varying portions of the transparent roof panel.
