Problems solved by technology

Since the weather strip is of course limited by the system and must be a soft part, so as not to prevent the pressure distribution mentioned at the beginning due to a bending of the pre-bent support component, this assembly becomes especially difficult in series production. particularly complex and susceptible to interference
In particular, an exact fit of the weather strip on the support member along the entire length of the wiper blade is difficult to achieve

Embodiment Construction

[0029] The wiper blade 10 shown in FIG. 1 has a strip-shaped, elongated, spring-elastic one-piece or multi-part support component 12 which is bent in the longitudinal direction in the unloaded state. On the raised upper or outer surface 16 of the support member 12 facing away from the glass pane 14 to be wiped ( FIGS. 1 and 2 ), on the middle section of the support member is arranged a for example flat against said upper or A connecting device 18 on the outer web 16, by means of which the wiper blade 10 can be releasably connected to a driven wiper arm 20 which is guided and moved on the vehicle body. A long rubber-elastic wiper strip 24 is arranged on the concave lower or inner web or edge 22 of the curved carrier element 12 facing the glass pane, the longitudinal axis of which is parallel to the carrier element. On the free end of the wiper arm there is an opposing connecting device, not shown in detail, which cooperates in a hinged manner with the connecting device 18 of th...

Abstract

The production process is for a wiper blade with at least one base body, comprising a wiper strip and a support element. The base body is positioned in a holding device so that the distance between at least some sections of the support element and the holding device is maintained. The wind deflector strip is grasped and at least one claw (46) formed on it is threaded onto the support element. The wind deflector strip is the placed over the sup[port element.

Description

technical field [0001] The invention relates to a method for producing a wiper blade, a device for carrying out the method and a wiper blade produced thereby. Background technique [0002] For a wiper blade with a spring clip-like support member, the wiper area swept by the entire wiper blade should ensure that the wiper blade pressing pressure from the wiper arm has distribute as evenly as possible. Due to a corresponding predetermined bending of the unloaded support member (that is to say if the wiper blade rests on the glass pane only with its two ends), the wiper blade is completely attached to the glass pane when it is in operation. The ends of the wiper strips on the windshield are acted upon by the subsequently tensioned support component against the glass pane, even with spherically curved motor vehicle glass panes where the radius of curvature changes for each wiper blade position. The curvature of the wiper blade must be slightly greater than the maximum curvatur...
