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, 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 single hinge links end elements of the first and second accordion fold portions. In a horizontal expansion mode, the first and second end elements have planar surfaces that are adjacent to each other and the first and second accordion fold portions extend outboard from either side of the adjacent end elements. In a vertically expandable mode, the end elements are co-planar with respect to each other. The first and second accordion fold portions are disposed above the respective first and second end elements and therefore the shade can be vertically expandable as desired to cover the interior of the automobile window.
