Definitions
- the present invention relates to a wiper blade for cleaning windows on motor vehicles according to the features of the preamble of claim 1.
- a wiper blade for cleaning windows on motor vehicles is known, which is covered by a corresponding protection profile.
- the protection profile ensures that e.g. during transport or transfer of the (new) vehicle, the wiper blade is not damaged. Due to the fact that a wiper lip facing the disk is formed on the protective profile, the disk can be cleaned despite the protective profile cover.
- the wiper lip formed on the protective profile according to DE 30 05 965 A1 consists of an elastically formed lower part which, according to the embodiments according to FIGS. 2 and 3, is connected to an upper part of the protective profile via a short web. Due to the web and the cross-section approximately triangular-shaped lower part a limited inclination of the lower part in relation to the normal of the disc is possible. The inclination is limited by the fact that depending on the wiping direction, the respective shoulder of the lower part comes to rest on the upper part of the second component. Due to the inclination of the wiper lip, the water can be removed from the window when the wiper blades are actuated.
- the object of the invention is to further optimize the function of the protective profile with the wiper lip formed thereon.
- the recesses are each formed on the right and left of the web end. Both recesses are symmetrical in shape and size and thus allow a lateral pivoting of the
- the recesses are formed as pocket-shaped grooves.
- the plastic protective rail can be produced by spraying or extruding, so that the recesses are advantageously already taken into account in the injection mold and thus a subsequent introduction of the recesses is no longer required.
- the protective profile or the protective rail is picked up in an advantageous manner on the mounting bracket body of the wiper blade.
- FIG. 1 shows a perspective partial view of a wiper blade with a protective rail
- FIG. 2 shows a cross section through the arrangement according to FIG. 1,
- FIG. 3a shows a cross section of a protective rail with a modified wiper lip according to a first embodiment
- FIG. 3b is an enlarged view X of the modified wiper lip according to Figure 3a
- FIG. 5a shows a cross section of a protective rail with a modified wiper lip according to a second embodiment
- Figure 5b is an enlarged view of the modified wiper lip according to Figure 5a and
- FIG. 5c shows a predefined end position of the modified wiper lip.
- the wiper blade shown in Figure 1 in a partial view for cleaning a window of a motor vehicle o.a. consists essentially of a mountable to a wiper arm mounting bracket body 2, on the underside of a squeegee 4 is fastened.
- two receiving strips 6a, 6b are fastened to the underside of the mounting bracket body 2, the latter engaging in corresponding longitudinal grooves 8a and 8b formed in the wiper rubber 4 for fastening the wiper rubber 4 to the mounting bracket body 2.
- the protective rail 10 consists of a v-shaped and upwardly open hollow body part 10a, in which substantially the squeegee 4 is recording.
- the hollow body part 10a is thereby bounded by two legs 10b and 10c, which form two pocket-shaped recesses 10d and 10e in the region of the support bar body 2.
- the pocket-shaped recesses 10 d, 10 e surround the support bracket body 2 adapted in this area to the shape of the recesses 10 d, 10 e, so that the protective rail 10 is held or supported by the recesses 10 d, 10 e on the mounting bracket body 2.
- This part of the protective rail also referred to as the first component, is made of plastic, preferably of a thermoplastic.
- a wiper lip 12 is formed on the v-shaped tapered end of the hollow body part 10a, as known from the prior art. With the help of the wiper lip 12 -trotz protective rail 10- the disc of the motor vehicle o.a. be cleaned.
- a second component 14 consisting of a thermoplastic elastomer (TPE) or of rubber is formed on the v-shaped end of the hollow body part 10a, which is a top part 14a and a bottom part 14b forming the actual wiper lip having.
- Upper and lower parts 14a, 14b are connected to each other via a web 14c.
- the recesses 16a and 16b are formed as pocket-shaped grooves. Through the recesses 16a, 16b, the length b of the web 14c is increased at a constant distance a between the upper and lower parts 14a, 14b.
- the web 14c becomes more elastic and, as shown in FIGS. 4a to 4c, can thus become lighter or better inclined.
- the inclination of the lower part 14b during the wiping process is important, since only in this inclined position removal of the water is secured by the disc.
- the lower part 14b is triangular in cross section, so that from a certain oblique angle the left or right upper shoulder 14b 'or 14b' 'of the lower part 14b on the upper part 14a comes to the concern.
