Date Oct. 2, 1997The invention relates to a wiper blade having a head (1) for fastening in the wiper holder bracket, a tilting rib (2), and a lip (3). It is characterized in that the head (1) comprises a stiff polymer, hardened by halogenation, with a Shore A hardness of 60 to 85; the tilting rib (2) comprises a comparatively soft, elastic polymer that is not hardenable or not substantially hardenable by halogenation, with a Shore A hardness of 50 to 75; and the lip (3) comprises a polymer hardenable by halogenation having a Shore A hardness of 60 to 85. The Shore A hardness of the polymer comprising the tilting rib (2) is less expediently by at least two units than the Shore A hardness of the polymer or polymers that form the head (1) and the lip (3).</p> |
