The invention relates to an end cap arrangement, more particularly for a wiper blade (), comprising an end cap main part () that can be fixedly connected to a main component () of a wiper blade (). It is proposed that the end cap arrangement comprise at least an end cap spoiler element () which is designed so that in an installed condition an installation opening () is left free for a wiper rubber ().

End cap arrangement

The invention relates to a wiper blade adapter unit with a wiper blade adapter (), which is provided for a connection to a wiper arm adapter and has at least one receiving area () having at least one contact surface () provided for fastening at least one carrier element () of a wiper blade. The invention states that the at least one contact surface () has a maximum length of 20 mm.

Wiper blade adapter unit

A wiper blade adapter device with at least one basic adapter (), which is provided for coupling to a spring rail (), and with a special adapter (), which is provided for coupling to a wiper arm adapter and, in a fitted state, is connected immovably to the basic adapter (). The wiper blade adapter device comprises a latching unit () which is provided for producing a latching connection between the basic adapter () and the special adapter ().

Wiper blade adapter 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 () with a wiper strip () which has a wiper lip () and a head strip () which is integrally formed on said wiper lip and, in a first longitudinal channel (), has a supporting element in the form of a spring rail () with a flat cross section, and has a spoiler () on that side which faces away from the wiper lip (). It is proposed that the spoiler () surrounds the head strip () on its longitudinal sides by means of guide rails ().
