Is it for a car or a stroller (or something else entirely)? In the car my wife uses a small bath towel. Roll the window down slightly, put the towel through the window, roll up the window. We also wrap the excess back over the top of the door then close the door so it doesn't flap around.
For a stroller, use a beach towel. Drape over the carriage area securing it at the handle.

I would suggest taking a normal umbrella, cutting one half off and securing it to a stroller. You would also use the "spokes" from the other side to keep the good side stiff.
Fix to push-chair, free-standing? How about re-skinning an umbrella?
