According to the execution, however, is the closure element at an additional, 5 i opposite each other

Guide elements !! latched, which do not serve to guide the wiper strip after the wiper blade has been installed. At these optionally correspondingly formed Hdteelementen the guide elements, a to the requirements can be correspondingly large closure member reliably attach.

According to an advantageous further development of the invention, the closure element is designed as a base plate with integral locking rib extending transversely to the plastic main bracket between the two _{side) 0} opposite hook-shaped guide elements can be locked, wobni two stops are integrally formed on the base plate, the seided in the axial direction of the guide elements enclose and fix the closure element axially immovable on the guide elements. The locking web fixes the closure element transversely to the plastic main bracket, while the stops bring the axially immovable fixing.

The closure element can be captively connected to the main plastic bracket in that the Closure element in one piece via an elastic strip on the end face of the plastic main bracket is formed and that on the base plate only on the front end of the plastic main bracket facing away from the end face of the elements, a stop is formed. This configuration also has the Advantage that the closure element with the plastic main bar can be produced in one operation.

In another embodiment, the closure element is designed as an end cover plate on which Detent springs are integrally formed, which in the axial direction between the two opposite one another hook-shaped guide elements can be latched and thereby the front end of the plastic main bracket Engage behind remote end faces of the guide elements. This locking element can with sufficiently long detent springs are formed so as to facilitate engaging. The arrangement is there preferably so that two divided by a slot across the width of the main plastic bracket Locking springs are provided, which with their Rastans.uzen the vertical legs of the guide elements reach behind. Clear guidance of the locking element when it clicks into place and a clean finish the plastic main bracket is achieved according to a further embodiment in that on the cover plate a base plate is formed with a guide web, which the two guide elements on the underside covers and which with the guide bar between the horizontal legs of the guide elements is led.

The invention is explained in more detail on the basis of various exemplary embodiments shown in the drawings. It shows

Fig. 1 in longitudinal section the end of a plastic main bracket with a closure element according to the invention,

F i g. 2 shows a cross section through the plastic main bracket along the line II-II of FIG. 1,

Fig. 3 in longitudinal section the end of a plastic main bracket with molded locking element,

4 shows the view of the underside of a plastic main bracket with a differently designed closure element,

FIG. 5 shows the plastic main bracket according to FIG. 5 in a longitudinal section. 4 along the line V-V and

6 shows a cross section through the plastic main bracket along the line VI-VI of FIG. 5.

In the embodiment according to FIGS. 1 and 2, the plastic main bracket 10 carries on its underside the hook-shaped retaining elements with their vertical legs 11 and the horizontal legs 12. For manufacturing reasons, these retaining elements are offset from one another along the two side edges of the plastic main bracket 10. A stop to limit the axial movement of the wiper strip can be formed at one end of the main plastic bracket, while at the end shown the two hook-shaped guide elements with their legs 13, 14 and 15, 16 are opposite each other and form a locking and guide receptacle. Pushing in the wiper strip is made easier because it is clearly guided by these two guide elements. If the wiper strip is pushed in, the locking element is locked into place.

In the embodiment shown, this closure element consists of a base plate 20 on which a locking web 23 with a locking lug 24 is integrally formed. This locking web 23 is between the horizontal legs 14 and 16 of the two guide elements introduced, the latching lug 24 behind the hinges 14 and 16 the guide elements engage. The closure element is thus transverse to the main plastic bracket 10 set. The two stops 21 and 22, which are the guide elements, are integrally formed on the base plate 20 enclose on both ends. Thus, the closure element is also axially immovable the main plastic bracket 10 set, the stop 22, the axial movement of the inserted Prevents the wiper strip and the stop 21 cleanly closes the plastic main bracket 10 on the front side.

Like F i g. 3 shows, the closure element can also be formed in one piece on the main plastic bracket 10 be, as the elastic strip 25 can be seen, which the base plate 20 with the end face of the plastic main bracket 10 connects. This closure element only requires the stop 22 for axial fixing, since the Strip 25 prevents an axial loosening of the closure element from the guide elements in the position of use. The closure element can, as shown in dashed lines, parts 20 ', 22', 23 ', 24' and 25 'show can be folded away so that it can be used with a simple injection molding tool along with the plastic main bracket 10 can be produced and that the wiper strip is unimpeded in the inclusion of the Plastic main bracket 10 can be inserted.

In the embodiment according to FIG. 4 to 6 is that Closure element in the axial direction in that formed by the two guide elements 13, 14 and 15, 16 Locking receptacle engaged. The closure element consists of a cover plate 30, which is the end face of the Guide elements at the end of the plastic main bracket 10 covers and on which the two through the slot 37 separate detent springs 31 and 33 are formed. These locking springs 31 and 33 are across the width of the The main plastic brackets 10 are arranged next to one another and are spaced apart from the vertical legs 13 and 15 of the two guide elements matched. The locking lugs 32 and 34 of these locking springs 31 and 33 snap into place on the end faces of the vertical legs 13 and 15, which are the end of the plastic main bracket 10 have turned away. As is particularly evident from FIG. 6 can be seen, prevent the horizontal legs 14 and 16 of the two guide elements so that the closure element can loosen transversely to the main plastic bracket 10. To the cover plate 30 of the closure element is the

Molded base plate 35, which covers the two guide elements on the underside. This base plate 35 carries a guide web 36, which is between the two horizontal legs 14 and 16 of the guide elements engages and the locking element clearly leads when it clicks into place.
