ABSTRACT:
A sunshade includes a flexible sheet with a hub generally positioned at its center. A plurality of radial arms are hinged to the hub about parallel axes which are perpendicular to the sheet. The outer ends of the arms are secured to the corners of the sheet. The sunshade is folded by pivoting the arms toward each other along a two-dimensional plane, so that it may be folded in the tight confines of an automobile's interior. In several embodiments, one or more arms are collapsible arms that facilitate the folding of the sheet. The collapsible arms are comprised of two sections connected by a bi-stable hinge, or comprised of spring-loaded telescoping sections. In another embodiment, the flexible sheet is of a wide rectangular shape supported by radial arms hinged to separate hubs positioned on left and right sections of the sheet. In yet another embodiment, the arms are all rigid, and the sheet includes a slit extending from its center to an edge. The slit is separable for enabling the folding of the arms and sheet.
