摘要:
The object of the invention is a wiper blade (10) with a wiper strip (12), in the lateral longitudinal grooves (20) of which spring rails (24) are inserted as springy supporting elements. The ends of the spring rails (24) are connected with one another by a bridge (32, 54, 62, 76) in that side parts (36, 66, 80) of the bridge (32, 54, 62, 76) are supported at the upper side of the spring rail (24) and engage recesses (28, 30) of the spring rails (24), whereas a middle part (34, 64, 78) of the bridge (32, 54, 62, 76) bridges a back strip (22) of the wiper strip (12), which forms the upper boundary of the longitudinal grooves (20). It is proposed that the spring rails (24), at their front faces, have short slots (28), which extend in the longitudinal direction of the spring rails (24) and which are engaged by the I-shaped angle pieces (38, 56) of the bridge (52, 54). Lower legs (40, 58) of the angle pieces (38, 56) are directed towards the middle of the spring rails (24), gripping these from below.
摘要:
A wiper blade is suggested for cleaning window panes in motor vehicles. The wiper blade (10) has an elongated rubber-elastic wiping strip (20) which can contact the window pane (18) and is provided at both of its longitudinal sides (30) with open-edged longitudinal receiving grooves which are arranged in a plane approximately parallel to the window pane and in which a strip-like, elongated, resilient carrying rail (12) is accommodated in each instance. The inner edges of the carrying rail (12) which face one another contact a longitudinal web (36) of the wiping strip remaining between the grooves (32) and the two carrying rails (12) are secured in their receiving grooves transverse to their longitudinal extension by a holder which is arranged at the upper strip surface (13) of the carrying rails remote of the window pane. The holder is provided with L-shaped claws (46), the first L-leg (48) traversing the outer edges (52) of the carrying rails and the second L-leg (50) engaging under the respective carrying rail (12). A wiper blade (10) which can be mounted in a particularly advantageous manner is provided when the distance (60) measured transverse to the longitudinal extension of the wiper blade (10) between the inner edges of the first L-leg (48) which face one another is less than the sum of the width (62) of the two carrying rails (12) plus the width (46) of the longitudinal web (36) of the wiping strip (20).
摘要:
A wiper blade (10) for windows, in particular of motor vehicles, is proposed that is equipped with a long, rubber-elastic wiper strip (14) that can be placed against the window (22), that is situated parallel to the longitudinal axis on a long, spring-elastic carrier element (12) to which a component (16) belonging to a device for attaching the wiper blade (10) to a driven wiper arm (18) is directly connected, whereby the carrier element (12) has springs (28, 30) designed in the shape of a strap lying in front of the window (22) in a plane that is basically parallel to the window, the bottom surfaces of the strap (13) of which face the window, the inner, adjacent longitudinal edges (32) of which have a distance between them and plunge individually into longitudinal grooves (54, 56) assigned to each longitudinal edge and open toward the longitudinal side of the wiper strip, and that are connected to each other by way of at least two transverse ribs (36) situated in the longitudinal direction with distance between them. A reliable and stressfree attachment of the wiper strip to the carrier element is insured when each transverse rib (36) has a center section (42) that extends at a distance from the top strap surfaces (11) of the springs (28, 30) so that bridge-like transverse ribs result, whereby the distance (34) between the two springs is less than the bridge width (46), and means of attachment (74, 76, 78) are situated on the carrier element (12) to secure the wiper strip (14) to the carrier element (12) in its longitudinal direction.

摘要:
The invention relates to a wiper blade (10) and to a method for producing a wiper blade (10), in particular for windows of motor vehicles, having a supporting element (12) supporting an elastic wiper strip (14) and at least one spring-loaded spring rail (38) having a connecting device (15) that can connect to a wiper arm (16) directly or by means of an adapter, and that is welded to the at least one spring rail (38) of the supporting element (12). The invention proposes that the connecting device (15) comprises at least one energy directing element (46) on the leg (36) including at least one spring rail (38), said element directing the welding energy to a defined point between the spring rail (38) and the connecting piece (15).
摘要:
A wiper blade for cleaning motor vehicles is proposed, which is provided with a band-like, elongated, spring-elastic support element (12). The lower band surface (13) of the support element (12) oriented toward the window (22) has an elongated, rubber-elastic wiper strip (14), which can be placed against the window (22), disposed on it so that the longitudinal axes of these two parts are parallel and the upper band surface (11) of the support element (12) has a wind deflection strip (42) disposed on it, which extends in the longitudinal direction of the support element, is provided with an attack surface (54) oriented toward the main flow of the relative wind, and is comprised of an elastic material. A considerable weight savings for the wiper blade is achieved if the wind deflection strip (42, 142, or 242) has two diverging legs (44, 46), viewed in cross section, which are connected to each other at a common base (48) and whose free ends (50, 52) oriented toward the window (22) are supported on the wiper blade (10), and the attack surface (54) is embodied on the outside of the one leg (44).
