These are the sweeper strips (often called window felts, squeegees, weatherstrip, window fuzzies, or anti-rattlers) that run horizontally on the rear hatch window of your SUV at the base of the window. They run on the inside and the outside of the glass. Replacement of you worn out strips produces a quieter, rattle free ride. Sold in sets of 2-pieces for the rear window with one in front and one behind the glass.
