I have a Rav4 with a 'rollerblind', it is leatherette with a metal bar and holes in it to match the headrest holes. At the other end there is sprung bar sewn into the leatherette which is compressed and then slots into the recesses that are at the back of the 'boot'. If you buy a shower curtain pole and cut to size and then get the leatherette, the metal bar, drill the holes, sew the leatherette to the size and fit - simps !!!!!!! would you like pix? I will attempt to upload some when I discover how it is done.
