The invention starts with 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. It is proposed that 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).
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, characterized in that 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).
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, characterized in that the sheet metal claw (106) has at least two claw feet (108) on an outer side of a spring rail (30, 32), between which the spring rail (30, 32) has a protuberance (110, 112, 114, 116), which overlaps the claw feet (108) upwardly, downwardly and/or laterally.
A method of manufacturing a 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 method comprising first mounting the sheet metal claw (24, 64, 106) is mounted on the spring rails (30, 32), wherein a spacer device (58) keeps the spring rails (30, 32) at a distance during assembly, then sliding the wiper strip (12) is slid between the spring rails (30, 32) and finally mounting the spoiler (16) and the end caps (18, 20).
