Abstract
Abstract The sun shade for the occupant of a wheelchair is comprised of a frame structure which can be mounted at the handle grips of a wheelchair. The frame structure includes at least two vertically disposed posts, at least one transverse member for bracing the two vertically disposed posts, and roof-forming members connected to the upwardly extending ends of the two vertically disposed posts. The shade is provided by a sheet of vinyl, canvas or the like and the sheet can be secured by way of snap-on buttons or similar releasable fasteners. The range of the sun shade can be increased by a forward visor portion. The roof portion can be folded to the rear of the wheelchair by being pivotally mounted to the vertically disposed posts.
