The invention is based on a wiper blade device having an adapter element () that can be fixedly connected to a main component () of a wiper blade (), said adapter element () comprising at least two side walls () facing one another, which at least partially delimit a receiving region () for at least one part of at least one holding element () for a wiper arm (). The invention states that at least one of the side walls () has at least one recess (), formed as a bearing opening (), for a bearing element ().

Wiper blade device

The invention is based on a wiper blade () with an elongate, spring-elastic carrying element () which is precurved in a concave fashion with respect to a vehicle window () and has two spring rails () which run parallel to one another in a plane, and having a wiper strip () which is held with a web () of its head strip () between the spring rails () via the carrier element (), said spring rails () being inserted in longitudinal grooves () on both sides of the web (), wherein the wiper strip () is secured in the longitudinal direction () relative to the carrier element () at least close to one of the ends of said wiper strip (). It is proposed that the spring rails () have, at the longitudinal sides facing one another in their end regions, clips () with cutters () which, in the mounted state, cut into adjoining walls of the longitudinal grooves ().

Wiper blade

The invention is based on a wiper blade () with an elongated, spring-elastic carrier element () which is pre-curved concavely with respect to a vehicle window () and has at least one spring rail, and with a wiper strip () which is held by the carrier element (), wherein the wiper blade () is secured relative to the carrier element () by an end cap () at least near to one end in the longitudinal direction (), which end cap () has, on one longitudinal side, an opening which can be closed off by a flap () which can pivot about a pivoting axis () running in the longitudinal direction () into an open position and into a closed position. It is proposed that securing means () be provided on the end cap () or the flap (), which securing means () can be moved by the activation of the flap () with the wiper blade () or with an element () connected thereto into an operative connection or out of an operative connection, wherein the securing means () are supported in the longitudinal direction () on the carrier element () or an element () which is permanently connected thereto, and said securing means () and/or become detached therefrom.

The invention is based on a wiper blade () with an elongate, spring-elastic carrying element () which is pre-curved in a concave fashion with respect to a vehicle window () and has two spring rails () which run parallel to one another in a plane, and having a wiper strip () which is held with a web () of its head strip () between the spring rails () via the carrier element (), said spring rails () being inserted in longitudinal grooves () on both sides of the web (), wherein the wiper strip () is secured in the longitudinal direction () relative to the carrier element () at least close to one of the ends of said wiper strip (). It is proposed that the spring rails () have, at the longitudinal sides facing one another in their end regions, clips () with cutters () which, in the mounted state, cut into adjoining walls of the longitudinal grooves ().

The invention relates to a connecting device which has a connecting element () of flat beam design fixed to a wiper blade () and an adapter () joined to said connecting element in an articulated manner, and also a joining element () that is joined to a wiper arm () and into the u-shaped cross-sectional profile of which the adapter () is inserted and, by means of a spring tongue () arranged on the top wall () thereof, is fixed to a pushbutton (), the connecting element () having a central web () running in the longitudinal direction of the wiper blade () and bearing a hinge shaft () projecting on the long sides thereof, which is mounted in laterally flexible hubs () in side walls () of the adapter (). According to the invention, the outwardly facing walls of the adapter (), namely the side walls (), the top wall (), and the end walls (), have a general wall thickness of at least two millimeters, and the hubs () are to be formed as blind holes, the cylindrical surfaces of which form radial sliding surfaces () and the end faces of which form axial sliding surfaces (), which are highly polished with an arithmetic mean roughness of Ra&#x3c;0.2&#x3bc;, and that the sliding surfaces () be the sole contact surfaces between the connecting element () and the adapter ().

Connecting device

The invention is based on a wiper blade () comprising a wiper strip (), in the lateral longitudinal grooves () of which two parallel spring rails () are inserted as a supporting element in the head strip (), wherein a spoiler () and end caps () are provided on the rails. The end caps () each connect with a flow profile () to the spoiler () and extend at the front sides facing the ends of the wiper blade () toward a wiper lip () over the spring rails (). It is proposed that at least one end cap () comprises a closeable assembly opening () in the region overlapping the spring rails () and the head strip ().

A wiper blade () comprising a rubber elastic wiper strip () in which a resilient rail () is inserted into a lateral longitudinal groove on each side of side of said wiper blade as a support element and laterally protrudes from the longitudinal groove, wherein the resilient rails () support terminal caps () while being held together at their ends and being fixed relative to the wiper strip () in the longitudinal direction by a bridge (), which is joined in a fixed manner to the resilient rails () at the lateral parts of said bridge and forms a free space for a top strip () of the wiper strip () in the central area of the bridge. It is proposed that the terminal caps () have detachable fixing means () that engage in the top strip () of the wiper strip (), wherein the axial movability of the resilient rails () relative to the wiper strip () is limited by the terminal caps ().
