Abstract

A non-articulated wiper blade (10), which is constructed of a wiper strip (12) having a wiper lip (14), two spring rails (30, 32) and a connecting device (22), wherein the spring rails (30, 32) engage in lateral longitudinal grooves of the wiper strip (12) that are open towards the outside and are clasped by claw feet (28, 68, 76, 108) of a sheet metal claw (24, 64, 72, 106) of the connecting device (22) from an outer narrow side. The claw feet (28, 68, 76, 108) are bent around the narrow sides of the spring rails (30, 32) during the assembly of the sheet metal claws (24, 64, 72, 106), wherein at least one layer (70) and/or an intermediate layer (48, 84) of plastic are provided between the claw feet (28, 68, 76, 108) on the one hand and the spring rails (30, 32) on the other hand, which layers are manufactured separately from the wiper strip (12) and are adapted to the claw feet (28, 68, 76, 108) as well as have a high coefficient of friction on their surface towards the sheet metal claw (24, 64, 72, 106) and towards the spring rails (30, 32).
