    [001] The present invention relates to a wiper blade.
    [002] In DE 10 2004 051 466 A1 a wiper blade according to gender is known. It has a wiper bar made of an elastomer material, which it touches with a wiper lip on a vehicle window. In order for the wiper bar to follow the curvature of the vehicle's glass, in longitudinal grooves on the side of the wiper bar, two elastic ribbon rails are inserted, extending parallel to each other, concavely curved for a wiper lip, such as support elements, which protrude laterally from the longitudinal grooves and are held together and fixed to each other at their ends by end caps. The end caps have on their longitudinal sides respectively two guide profiles extending parallel to the longitudinal direction of the wiper bar with guide areas and fillets. The guide areas guide the end caps on the portions of the elastic rails protruding from the longitudinal grooves.
    [003] Each end cap has at least one shaped elastic tongue, extending essentially parallel to the upper side of the top bar. On its side pointing towards the top bar, the elastic tongue features a locking protrusion. It is configured in a wedge shape and rises towards the end of the wiper blade in its height, so mounting the end cap is facilitated. Upon a rotational movement of the tongue, the side of the wedge-shaped locking protrusion facing towards the end is raised more and more so that the end cap is secured against extraction of the tongue. So that the locking protrusion cannot be released inadvertently, a locking latch is provided, which is guided into a recess in the end cap and in the locking position presses the elastic tab against the top bar of the wiper bar and the blocks.
    [004] In addition to the locking projection, the elastic tongue can have on the side facing the elastic rails two locking pivots arranged laterally to the locking projection and symmetrical thereto, which, in the assembled state, engage in locking holes, which they are arranged in the extreme region of the elastic rails and serve as an additional guide. While the plug-in pivots are made cylindrical, the plug-in holes are made as oblong holes, so that the elastic rails have a limited play in the longitudinal direction. In addition, the snap-in pivots determine the distance of the elastic rails from each other. The wiper bar fillet thus has enough free space between the elastic rails for good functionality. Description of the Invention
    [005] According to the invention, the snap-in projections are provided on the side legs far from the wiper lip of the guide profile, while the other side legs of the guide profile cover the snap-in projections for the front wall of the end cap and end before her. As the side legs, which lie closest to the sealing lip, are not molded to the front wall, they are resilient to a significant extent, so that both side legs of a guide profile on assembly yield, thereby in total. a large elastic path results, without the material being required. However, the lateral legs of the guide profiles are made sufficiently rigid, so that a lock is not required for the projections to be locked into position.
    [006] The snap-in protrusions can either be provided on the legs on the sides of the guide profiles furthest from the wiper lip or on the side legs of the guide profiles closest to the wiper lip. This alternative is more convenient because the side leg positioned closest to the wiper lip can be more easily modified for the added function of an elastic tongue. Furthermore, the snap-in protrusion when disassembling the end cap can be more easily reached with a tool and loosens the snap-in position.
    [007] According to an embodiment of the invention, it is proposed that, when an arrangement of the snap-in boss on the side leg farthest from the wiper lip, the other side leg for the end of the associated elastic rail ends before the maximum elevation of the snap-in boss , so that a gap is formed, through which the snap pivot can be activated from outside. But there is also the possibility that the guide leg closest to the wiper lips in the mounted position overlies the snap pivot for the wiper lip, so that it and the opening in the elastic rail are protected from dirt and noise is reduced. of flow in that region.
    [008] Conveniently, the height of the mating boss decreases in the mounting direction. It thus forms a stop chamfer for easy assembly. In the opposite direction, the snap-in boss drops abruptly, which reinforces the locking effect. According to another configuration, it is proposed that the recesses in the elastic rails are made symmetrical to the longitudinal central plane of the respective elastic rail. This ensures that the elastic rails are equal on both sides of the wiper blade and that the plurality of parts is kept small.
    [009] The invention relates both to a wiper blade with an end cap and also to the end cap as an individual part, which can be used in combination with the wiper blade according to the invention. The end cap is characterized by the fact that the side legs of each guide profile are made partially elastically resilient and serve as elastic tabs, and the side legs facing the wiper lip end before the front wall of the end cap, with the height decreases in the mounting direction and thus forms a stop chamfer, while the mating boss drops abruptly in the opposite direction. It is therefore convenient that the extension of the mating protrusion in mounting direction is greater than transversely. An elastic rail is adapted to this, with a corresponding oblong hole as a recess, and for better functionality an appropriate clearance can be provided between the fitting protrusion and the recess.
    [010] Other advantages are inferred from the following description of the design. In the drawing are represented examples of implementation of the invention. The design and description contain numerous features in combination. The technician conveniently considers the features individually as well and assembles them for other convenient combinations.

    [020] A wiper blade 10 in flat bar construction mode has a wiper bar 14, which wiper lip 16 is joined by a bend thread 18 to a top bar 22. Between the wiper lip 16 and the top bar 22 are support bars 20 laterally arranged. Furthermore, in the top bar 22, lateral longitudinal grooves 24 are provided, which form a thread 25 between them. The part of the top bar 22 opposite the wiper lip 16 is referred to as the reverse bar 26.
    [021] In the longitudinal grooves 24 is inserted on each side of the wiper blade 19 an elastic rail 28, which protrudes laterally in a good piece. Guided on the projecting part of the elastic rail 28 in the longitudinal direction to both sides of a connecting element 32 for the articulated connection with a wiper arm not shown is a deflector 34. The deflector 34 is optional and can be dispensed with in certain cases of application. End cups 36 are provided at the ends of the wiper blade 10. These have guide profiles 44 on their longitudinal sides, with which they are guided in the parts of the elastic rails 28 protruding from the grooves 24. The elastic rails 28 in the form of a strip are then located between the side legs 46 and 48 of the guide profiles 44. The side legs 46 on the side opposite the wiper lip 16 can be joined to an intermediate wall, which forms a recess 42 for the back bar 26 of the wiper bar 14. When the wiper blade 10 has a deflector 34, the end caps 36 also have flow profiles 38 and have recesses 40 for connection to the deflector 34.
    [022] In order for the wiper blade 10 to follow a curved vehicle glass 12, the elastic rails 28 are curved concave to the wiper lip 16, so that in the unloaded state (Fig. 1) only the ends of the wiper blade 10 touch the vehicle glass 12.
    [023] In order that on both sides of the wiper blade 10 equal elastic rails can be used, it is advantageous that the recesses 30 of the elastic rails 28 are configured symmetrical to a central longitudinal plane 64 of the elastic rails 28. It may then be convenient that the part of the elastic rail 28, which immerses in the longitudinal groove 24 of the wiper bar 14, is narrower than the projecting part.
    [024] As can be seen in Figures 3 and 5, the elastic rails 28 are fixed between the mating projections 50, which engage the recesses 30 of the elastic rails, and the inner side of the front wall 56 of the extreme side of the end cap 36 in longitudinal direction. In order that unambiguous abutment areas result between the front sides of the elastic rails 28 and the inner side of the front wall 56 of the outer shell 36, the corners of the elastic rails 28 are interrupted, whereby sufficient free space is formed in the corners. Furthermore, on the inner side of the front wall 56, a recess 58 is provided for the top bar 22 of the wiper bar 14.
    [025] When mounting the end cap 36, it is moved in the mounting direction 52 with the guide profiles 44 on the elastic rails 28, with the guide profiles 44 due to the elastically resilient configuration of the side leg 46 expands , until the engaging protrusions 50, 62 can engage the recesses 30 of the elastic rails 28. In the engaged state of the engaging protrusion 50, the end of the side leg 48 faces the front wall 56, which is located closest to the wiper lip 16, is in the region of the stop groove 54, so that the engaging projection 56 is only partially covered and can be activated from that side by the gap between the side leg 48 and the front wall 56.
    [026] In the execution according to Fig. 7, the side legs 60 closer to the wiper lip 16 of the guide profiles 44 are made longer, so that in the fitted position they cover the engagement protrusions 56, 62 for the lip of cleaner 16, but they end before the front wall 56. As a result, the recesses 56, 62 and the recesses 30 are protected against dirt. Fig. 8 shows a corresponding longitudinal section through an end cap 36 in the execution as shown in Fig. 7.
    [027] The embodiment according to Fig. 9 differs from the previously described embodiments especially in that the snap-in projection 62 is molded to the lower side leg 60 of the guide profile 44 and engages on the side facing the wiper lip 16 on the recess 30 of the elastic rail 28.
