The present invention is directed to a collapsible cover for protecting an occupant in a seating unit having a head region and a foot region. The cover has a body comprised of a flexible material having a top portion and at least one side wall portion, the top portion having a generally ellipse shape and having a length to span the distance between the head region and foot region of the seating unit and a width to span the width of the seating unit. The sidewall portion is connected to the top portion along a substantial portion of the periphery of the top portion to provide an arched configuration to the top portion. The cover further has a single closed loop frame member made of a flexible, coil-able, resilient material, that is secured along the length of the structure's membrane body so as to assume an ellipse-like shape when viewed from above, that is bent into an arched configuration about its minor axis. The closed loop frame member is movable between an extended orientation to allow the cover to be attached to the seating unit and a collapsed orientation to allow for a reduced size of the cover for transport and storage and is connected to the periphery of the top portion to provide in the extended orientation an arched ellipse shape about the length of the top portion. The cover also has a means for releasably attaching the cover to a seating unit.

The invention claimed is: 1. A collapsible cover for protecting an occupant in a seating unit having a head region and a foot region, the cover comprising: a body comprised of a flexible material having a top portion and at least one side wall portion, the top portion having a generally ellipse shape and having a length to span the distance between the head region and foot region of the seating unit and a width to span the width of the seating unit; the sidewall portion comprising a pair of generally semi circular side panel membranes to either side of the top portion connected to the top portion along a substantial portion of the periphery of the top portion to provide an arched configuration to the top portion; a closed loop frame member of a flexible coil-able material, being movable between an extended orientation to allow the cover to be attached to the seating unit and a collapsed orientation to allow for a reduced size of the cover for transport and storage the dosed loop frame member being connected to the periphery of the top portion to provide in the extended orientation an arched ellipse shape about the length of the top portion; and a skirt attached to the side panel membranes such that the skirt allows for releasable attachment of the cover to the seating unit. 2. A collapsible cover for a seating unit according to claim 1 including a restraining element to retain the collapsed cover in its reduced-size coiled state. 3. A collapsible cover for a seating unit according to claim 1 wherein the top portion is provided with a closure to allow the top portion to be opened and closed such that an occupant can enter and leave the seating unit without removing the collapsible cover. 4. A collapsible cover for seating unit according to claim 1 such that the skirt allows for releasable attachment of the cover to the seating unit by means of a draw string. 5. A collapsible cover for a seating unit according to claim 1, wherein a stiffening means is provided to span the distance between the frame member and the seating unit to aid in stably fastening and spacing the top portion above the seating unit. 6. A collapsible cover far a seating unit according to claim 1 including a frame sleeve provided along the periphery of the top portion for holding the closed loop frame member. 7. A collapsible cover for a seating unit according to claim 1 wherein a substantial amount of the material of the top portion allows passage of air, but blocks insects. 8. A collapsible cover for a seating unit according to claim 1 wherein a substantial amount of the material of the sidewall portion allows passage of air, but blocks insects. 9. A collapsible cover for a seating unit according to claim 1 that self-erects into the extended orientation from the collapsed orientation. 10. A collapsible cover for a seating unit according to claim 1 including at least one layer of supplemental cover material of a size and shape similar to the top portion that can be attached to said top portion to provide an additional layer of protection from weather conditions to an occupant of the seating unit. 11. A collapsible cover for a seating unit according to claim 1 wherein the frame member is constructed of a material selected from the group consisting of spring steel, synthetic polymer material, metal alloy, and composite material. 12. A collapsible cover for a seating unit according to claim 1 wherein the frame member is constructed of a material selected from the group consisting of flat cross section spring steel wire, flat cross section synthetic polymer material, flat cross section metal alloy and flat cross section composite material that is treated so as to resist corrosion. 13. A collapsible cover for a seating unit according to claim 12 having pre-coil geometry that in the extended orientation permits rapid movement into the collapsed orientation without the requirement to twist the cover.
