Definitions
- the invention relates to a wiper blade according to claim 1.
- Wiper blades for cleaning windows on vehicles are known in a wide variety of designs. Wiper blades are also known in particular
- the object of the invention is to show a wiper blade which is characterized by a simplified assembly.
- a wiper blade is designed according to claim 1.
- the wiper strip is injection molded onto the at least one spring rail, ie the spring rail is inserted into the injection mold used for this purpose during injection molding of the wiper strip, so that after the injection molding, the wiper strip and the spring rail form a unit. Subsequent assembly work to complete the Wiper blades can be omitted.
- the design freedom not only for the wiper blade as a whole is significantly increased compared to the previous training, in particular also in that after the injection molding of the wiper strip, no assembly processes are necessary, by which the freedom of design of the parts to be handled is not insignificantly restricted.
- Another significant advantage of the design according to the invention is that it is possible in a particularly simple manner by extrusion coating to cover the edges of the spring rail made of metal by the material of the wiper strip, which in particular also avoids the risk of injury.
- Figure 1 in a simplified representation and in side view of a wiper blade according to the invention.
- Figure 2 is an enlarged view of a section along the line I - I of Figure 1; 3 shows an enlarged representation and in longitudinal section of one end of the wiper blade of FIG. 1;
- FIG. 4 shows another possible embodiment in a representation of FIG. 2.
- the wiper blade generally designated 1 in the figures, consists essentially of an elongated wiper strip 2 made of an elastomeric material by injection molding and of a band-shaped spring rail 3 made of a resilient flat material, for example spring steel, which is made of the material of the Wiper strip 2 is largely overmolded.
- the spring rail 3 which, like the wiper strip 2, extends over the entire length of the wiper blade 1, has, for example, a constant width with parallel long sides 3 'and 3''.
- other shapes for the spring rail 3 are also conceivable, for example in such a way that the width of the spring rail 3 decreases toward one or both ends of the wiper blade 1.
- the wiper strip 2 is shaped in such a way that it forms on the underside of the spring rail 3 a profile section 4 that extends over the entire length of the wiper blade 1 and is flat-band-like in the embodiment shown, the larger surface sides of which parallel to the surface sides the spring rail 3 is located and on the side facing away from the spring rail 3 via a tilting web 5, the wiper lip 6 is formed, which also extends approximately over the entire length of the wiper blade 1 and is in use against the window to be cleaned.
- the wiper strip 2 then forms a profile section 7, which on a longitudinal side of the wiper blade 1 covers the longitudinal edge 3 ′ there of the spring rail 3 with a strip-like area 7 ′ and at the two ends of the wiper blade 1 ends of the spring rail 3 overlap with a region 1 ′′ like a clamp, which also merges into the lower profile section 4 there.
- the wiper strip 2 is provided with a recess 8.
- This recess 8 is formed by a holder which is used for the production of the Wiper blade 1 used injection mold is provided, namely for the correct fixation of the spring rail 3 in this form.
- a plurality of recesses, each having a short length can also be provided, with the upper profile section 7 then extending on both sides of each short recess 8 via a clip 1 corresponding to the region 1 ′′ and the spring rail 3 on the long edge 3 ′′ Area merges into profile section 4.
- the design is such that this edge does not protrude over the relevant long side of the wiper blade i, but lies within the recess (s), so that protection against injury from the long edge 3 '' is also provided on this long side of the wiper blade 1.
- the wiper strip 2 is designed like a spoiler on its upper side, ie on the upper side of the profile section 7.
- the wiper strip 2 has a greater height on one longitudinal side of the wiper blade, ie in the area of the long edge 3 '' in an axial direction perpendicular to the plane of the spring rail 3 than on the other long side in the area of the long edge 3 ', so that there is on the top
- the edge 10 has a height that changes along the longitudinal axis L, that is to say in the middle of the wiper blade 1, that is to say where the attachment with the windshield wiper arm (not shown) takes place, the height of the edge 10 is greatest and increases with the two Ends of Wiper blade hm.
- a plurality of openings 11 are provided in the spring rail 3, which openings are penetrated by the material of the wiper strip 2 and via which a connection is established between the upper profile section and the lower profile section 4.
- Figure 4 shows in a representation like Figure 2 as a further embodiment of a wiper blade la, in which the wiper strip 2a is designed so that the material of the wiper strip 2a, the spring rail 3 on its long edge 3 'with a portion or area 1''' of Profile section 7 engages and covers like a clamp, on the longitudinal side of the wiper blade la opposite the recess 8. Otherwise, the wiper strip 2a corresponds to the wiper strip 2, also with regard to the cross-sectional shape. LIST OF REFERENCE NUMBERS
