The invention comprises an overhead shade device adapted to be attached to a mobility aid. The invention has an elongate shaft having an upper end and a lower end. The shaft is attached to the mobility aid at the shaft's lower end in a manner that holds the shaft functionally vertically. A shade is attached to the upper end of the shaft. The shade may be an umbrella-type shade, or a fan, or other functionally horizontal surface that shades the user when deployed. In one embodiment of the invention, the perimeter of the shade when opened includes a base side and an arc of less than 360 degrees, and more preferably, an arc of less than about 200 degrees. The base side does not extend significantly beyond the outer edge of one side of the user and/or mobility aid when said shaft is held in a functionally vertical orientation. The area of the shade may be continuously variable between its limits.
