Problems solved by technology

[0004] A disadvantage of the prior art is that it is generally not possible to produce a homogeneous welded connection when welding the support rail to the rail support, since PET and PBT have different plastic properties such as structure, melting point and viscosity

Embodiment Construction

[0025] figure 1 A plurality of components are shown, which according to one embodiment form a wiper blade 10 , in particular for a windshield wiper for cleaning motor vehicle windows. According to one specific embodiment, the wiper blade 10 is designed as a flat beam.

[0026] The wiper blade 10 has, for example, a two-part spoiler 88 , 89 , two end caps 46 , 48 , two support rails 62 , 64 and a wiper strip 14 with at least one wiper lip 20 . A connecting element 100 is provided for fastening the wiper blade 10 on an associated wiper arm, preferably according to the so-called side-lock or top-lock principle. The connecting element has, for example, a base adapter 120 and a fastening spring 110 . According to one specific embodiment, the base adapter 120 can be connected to the support rails 62 , 64 in a hingeless and permanent manner, as described below image 3 and 4 described in . Fastening spring 110 can be fastened to an associated wiper arm and can be articulatedly c...

Abstract

The blade (10) has a wiper strip (14) provided at carrier rails (62, 64). The carrier rails are fastened to rail holders of a connection element (100). The carrier rails comprise plastic casings formed from thermoplastic resin e.g. polyethylene terephthalate (PET). The holders are sectionally made of another plastic. The holders include groove-like longitudinal channels for accommodating the carrier rails, where the thermoplastic resin is sectionally provided in an area of the channels. The holders are integrally formed with a fastening element by plastic injection in two-component techniques. An independent claim is also included for a method for welding a carrier rail.

Description

technical field [0001] The invention relates to a wiper blade for a windshield wiper, the wiper blade having a wiper strip, on which a support rail is arranged, which is fastened to an associated rail support of a connecting element, wherein the The support rail has a plastic coating made of a first thermoplastic at least in the region of the rail mount. Background technique [0002] Wiper blades are known from the prior art, the wiper strip of which has a rear strip on which is guided an associated support rail, which is generally designed as a spring plate. The support rail is fastened in a rail receptacle of a connecting element which has a fastening element, for example a fastening spring, for fastening to a wiper arm of an associated corresponding windshield wiper. For conventional wiper blades, the rail support is generally made of glass-fiber-reinforced polybutylene terephthalate (PBT) and the support rail has a coating of polyethylene terephthalate (PET) . [0003...
