Problems solved by technology

[0004] The disadvantage of such welding is that the welding process parameters have to be followed very precisely in order to withstand high bending and shearing forces in this area during the service life of the wiper blade
This causes high additional costs especially for wiper blades produced in large quantities

Embodiment Construction

[0027] exist figure 1 The wiper blade 10 shown in has a strip-shaped elongated spring-elastic carrier element 12 ( figure 1 and 2 ), an elongated rubber-elastic wiper strip 14 is fastened parallel to the longitudinal axis on the lower, concave strip side facing the glass of the carrier element. On the upper side of the carrier element 12 , which can also be referred to as a spring rail, protruding away from the glass, in the middle section of the carrier element is arranged a connecting device 15 on the wiper blade side, by means of which connection The device 15 can articulate the wiper blade 10 with the figure 1 The wiper arm 16 outlined in dot-dash line is releasably connected. the edge figure 1 The wiper arm 16 driven to swivel in the direction of the double arrow 18 in the direction of the arrow 24 faces the glass to be wiped—for example, the windshield of a motor vehicle is loaded—the surface of the windshield figure 1 Outlined by dotted line 22 in .

Abstract

The invention relates to a wiper blade (10) and to a method for producing a wiper blade (10), in particular for windows of motor vehicles, having a supporting element (12) supporting an elastic wiper strip (14) and at least one spring-loaded spring rail (38) having a connecting device (15) that can connect to a wiper arm (16) directly or by means of an adapter, and that is welded to the at least one spring rail (38) of the supporting element (12). The invention proposes that the connecting device (15) comprises at least one energy directing element (46) on the leg (36) including at least one spring rail (38), said element directing the welding energy to a defined point between the spring rail (38) and the connecting piece (15).

Description

technical field [0001] The invention relates to a wiper blade, in particular for a window of a motor vehicle, and to a method for producing the wiper blade. Background technique [0002] In the case of wiper blades of the aforementioned type, the carrier element should ensure that the wiper blade pressing force from the wiper arm is distributed as uniformly as possible on the glass over the entire area of ​​the wiper area swept by the wiper blade. Even if the radius of curvature of a spherically curved motor vehicle glazing varies at each wiper blade position, the corresponding curvature of the unloaded load-bearing element—that is, when the wiper blade is not resting on the glazing—in the During operation of the wiper blade, the end of the wiper strip which rests completely against the glass passes through and then the tensioned carrier element is also loaded towards the glass. The curvature of the wiper blade must therefore be somewhat greater than the greatest curvature ...
