A sunshade has ribs which emanate from a hub and are connected intermediate their ends to struts which are in turn connected to a center sleeve. When the sleeve is remote from the hub, the ribs and struts lie alongside each other in a collapsed position in which they are generally parallel to the axis of the hub. However, as the sleeve is moved upwardly toward the hub, the struts swing outwardly and push the ribs outwardly. Indeed, the struts pass through an over center position before the sleeve comes against the hub, and when the sleeve is against the hub, the ribs are in an extended position wherein they radiate from the hub. Each rib at its outer end has a rib extension connected to it, and these rib extensions fold between extended positions, wherein they form continuations of their respective ribs, and folded positions wherein they lie alongside their respective ribs. A fabric cover is connected to the ribs and rib extensions and folds with them. Some of the ribs have legs depending from them, and a head band is attached to the lower ends of these legs.
