ABSTRACT:
The foldable automobile window shade generally includes a first plurality of substantially rigid, planar elements joined together by hinges such that they form a first accordion fold portion of the shade. The shade also includes a second plurality of rigid, planar elements forming a second accordion fold portion of the shade. The shade also includes a hinge that links the first and second accordion fold portions. The hinge may be a pop-out tab in one of the elements forming the first accordion fold portion which cooperates with a through passage in one of the elements forming the second accordion fold portion. In another embodiment, the hinge may be a clip having depending and upstanding U-shaped legs that grip the elements in either the horizontal expansion mode or the vertical expansion mode. The planar elements forming the accordion fold portions may be triangularly shaped such that the hinge linking the first and second fold portions is angularly displaced with respect to the fold lines in the fold portions. With triangularly shaped elements, one of the fold portions can be configured to form a solid triangular body or pyramid that notifies others of an emergency situation. In that embodiment, the further hinge cooperates with a through passage in a remote triangular element thereby forming the solid, triangular body.
