The big shade on my rear window was experiencing the bent end brackets like Daryles pic. I bent them back numerous times but they always splayed back out and blind would be found laying on top of the couch after travel.

I took a block of styrofoam and stuffed it up between the end bracket and the valence on both ends. It has not fallen since, and it works to retract with my gentle encouragement. I can't tug on it and expect it to retract on its own. I have several that are that way.
