When it's parked too long in the sun, exposed to the heat that shrinks those door window frame covers or whatever they're called, that's what happens. Those become brittle with age, and mind you these are 20+ year old cars. If these have been kept garaged, chances are those covers will not shrink and shrivel up like those in your pics.
I think you can get them brand new from the dealer but it'll be really costly just for those. I don't recall the prices off hand though.
