Abstract

A wiper blade (10) for cleaning windows (26) of motor vehicles has an elongated, rubber-elastic wiper strip (14), which can be pressed against the window (26) to be wiped and is held substantially parallel to the longitudinal axis on an elongated, spring-elastic support element (12), to whose middle portion, remote from the window (26), a connection device (16) for counterpart connection means of a driven wiper arm, which means can be loaded toward the window (26), are disposed. Problem-free, economical disposition of the connection device (16) on the support element (12) is obtained if the connection device (16) is embodied as a separate component and secured to the support element (12) by means of an adhesive.

Claims

1. A wiper blade (10) for motor vehicle windows, having an elongated, rubber elastic wiper strip (14), which can be pressed against the window (26) to be wiped and is held substantially parallel to the longitudinal axis of an elongated spring elastic band-shaped support element (12), to whose middle portion, on the side remote from the window, a connection device (16) for a driven wiper arm, loadable toward the window, is secured, and the connection device (16) is embodied as a separate component, said support element (12) being flat and having two parallel sides including one side to which the wiper strip (14) is directly fixed In continuous contact therewith along its entire length and the other side to which the connection device (16) for the wiper blade is directly fixed, and the connection device (16) has at least one flat side with which it comes into direct contact to the flat side of the support element (12) and is secured to the flat side of the support element by an adhesive.

2. The wiper blade of claim 1, wherein the connection device (16) has a substantially U-shaped cross section and rests with the base (30) of the U, joining its two legs (32, 34) of the U, flatly on the side, remote from the window, of the band-shaped support element (12).

3. The wiper blade of claim 2, wherein the base (30) of the U of the connection device (16) is provided, on its side remote from the legs (32, 34) of the U, with protrusions (60, 62), which are spaced apart from one another crosswise to the longitudinal extent of the support element (12) by a distance (64) which is adapted to the width of the support element.

4. The wiper blade of claim 3, wherein the protrusions (60, 62) are embodied as strips, which extend longitudinally of the support element (12).

5. The wiper blade of claim 2, wherein at least one shoulder (40 or 42), pointing in the longitudinal direction of the support element (12), is disposed on the connection device (16) and a counterpart shoulder (44 or 46) of the support element (12) is associated with it.

6. The wiper blade of claim 5, wherein the connection device (16) is provided at least two shoulders (40 and 42), pointing in opposite directions, with each of which a counterpart shoulder (44 and 46) of the support element (12) is associated.

7. The wiper blade of claim 6, wherein the shoulders (40 and 42) of the connection device (16) are embodied on a protrusion (38) of the connection device (16), and the counterpart shoulders (44) and (46) are embodied on a recess (48), associated with the protrusion (38) of the support element (12).

8. A wiper blade (10) for motor vehicle windows, having an elongated, rubber elastic wiper strip (14), which can be pressed against the window (26) to be wiped and is held substantially parallel to the longitudinal axis of an elongated, spring-elastic band-shaped support element (12), to whose middle portion, on the side remote from the window, an elongated connection device (16) for a driven wiper arm, loadable toward the window, is secured, and the connection device (16) is embodied as a separate component and is secured to the support element (12) by means of an adhesive, the connection device 16 has a substantially U-shaped transverse cross-section and rests with the base 30 of the U, joining its two legs (32, 34) of the U flatly on the side, remote from the window, of the band-shaped support element 12, the base (30) of the U of the connection device (16) is provided, on its side remote from the legs (32, 34) of the U, with protrusions (60, 62), which are spaced apart from one another crosswise to the longitudinal extent of the support element (12) by a distance (64) which is adapted to the width of the support element, the protrusions (60, 62) are embodied as strips, which extend longitudinally of the support element (12) on the free ends of the strips (160, 162), remote from the base (30) of the U, clawlike attachments (166, 168) oriented counter to one another are disposed, and that the spacing between the clawlike attachments (166, 168) and the outside, remote from the legs (32, 34) of the base (30) of the U is adapted to the thickness (170) of the support element (12).

9. A wiper blade (10) for motor vehicle windows, having an elongated, rubber elastic wiper strip (14), which can be pressed against the window (26) to be wiped and is held substantially parallel to the longitudinal axis of an elongated spring elastic band-shaped support element (12), to whose middle portion, on the side remote from the window, a connection device (16) for a driven wiper arm, loadable toward the window, is secured, and the connection device (16) is embodied as a separate component, said support element (12) being flat and having two parallel sides including one side to which the wiper strip (14) is directly fixed in continuous contact therewith along its entire length and the other side to which the connection device (16) for the wiper blade is directly fixed, and the connection device (16) has at least one flat side with which it comes into direct contact to the flat side of the support element (12) and secured to the flat side of the support element by an adhesive, the connection device (16) has a substantially U-shaped transverse cross section and rests with a base (30) of the U, joining its two legs (32, 34) of the U, flatly on the side, remote from the window, of the band-shaped support element (12), shoulders (40,42) of the connection device (16) are embodied on a protrusion (38) of the connection device (16), and counterpart shoulders (40,46) are embodied on a recess (48) associated with the protrusion (38) of the support element (12).
