The invention if based on a wiper blade for cleaning windows ( ) of motor vehicles, having a wiper strip ( ) retained by a support bracket system ( ). At least one gutter ( ) oriented in the longitudinal direction ( ) is disposed directly or indirectly on the support bracket system ( ) and conducts water outward of a main viewing field.

Wiper element for cleaning motor vehicle windows

In a windshield wiper device each wiper blade has a wiper element with a lip applied to a windshield to be wiped and a back portion held in an elastic rail made from elastic plastics. The wiper element is secured on the elastic rail against mutual displacement in the direction of elongation of the rail. A two-part yoke system which engages the elastic rail provides for a uniform distribution of contact pressures exerted on the wiper elements.

Windshield wiper device for motor vehicles

A wiping arrangement for wiping a vehicle window has a wiper arm having a free bifurcated end portion which defines a gap extending lengthwise of the arm, a wiping blade, an element for connecting the wiping blade with the wiper arm in response to sliding entry of the element into the gap, and an element for disconnecting the wiping blade from the wiper arm to permit its separation therefrom. The connecting element has two projecting sections which are biased apart from one another and toward prong sections of the wiper arm. One of the projecting sections of the connecting element has an engaging formation which engages this an engaging formation of one of the prong sections of the wiper arm. Thereby the connecting element and the wiping blade secured thereto become connected with the wiper arm. The disconnecting element includes a handle provided on one projecting portion of the connecting element and extending outwardly beyond the prong sections of the wiper arm. The handle portion urges the one projecting section of the connecting element toward the other projecting section thereof so that the engaging formations become disengaged from one another, whereby the connection of the connecting element and the wiping blade with the wiper arm is interrupted. After this, the wiping blade can be withdrawn from the wiper arm without removing the latter from a vehicle window.

Wiping arrangement for wiping a vehicle window

A wiping arrangement for wiping a vehicle window has a wiper arm having a hook-shaped end part which bounds a gap, a wiping blade, and a connecting element for connecting the wiping blade with the wiper arm in response to sliding entry of the connecting element into the gap. The connecting element has two projecting portions which are biased apart from one another and toward sections of the wiper arm. One of the projecting portions of the connecting element has an engaging formation which engages with an engaging formation arranged in one of the arm sections of the wiper arm so as to provide the above-mentioned connection. The one projecting portion of the connecting element is provided with means for urging this portion apart from the other projecting portion so that the engaging formations become disengaged from one another and thereby the wiping blade can be removed from the wiper arm. The urging means extends outwardly beyond a face of the wiper arm which faces away from the vehicle window.
