Patent ID: 8479349

Claim:
A vehicle provided with at least two windscreen wiper devices each comprising an elastic, elongated carrier element, as well as an elongated wiper blade of a flexible material, which can be placed in abutment with a windscreen of the vehicle to be wiped, each wiper blade including opposing longitudinal grooves on its longitudinal sides, in which grooves spaced-apart longitudinal strips of the carrier element are disposed, wherein neighboring ends of said longitudinal strips are interconnected by a respective connecting piece, which windscreen wiper devices each comprise a connecting device for a respective oscillating arm, wherein each oscillating arm is pivotally connected to its corresponding connecting device about a pivot axis near one end, with the interposition of a joint part, wherein each joint part comprises at least one resilient tongue engaging in a correspondingly shaped hole provided in its corresponding oscillating arm, and wherein said resilient tongue is rotatable along a hinge axis between an outward position retaining a wiper blade onto its corresponding oscillating arm and an inward position releasing said wiper blade from its corresponding oscillating arm, each joint part has an at least substantially U-shaped cross-section at the location of its attachment to its corresponding connecting device, and wherein each said joint part, in at least one leg of said U-shaped cross-section, is provided with at least one laterally extending protrusion and its corresponding oscillating arm has an at least substantially U-shaped cross-section at the location of its connection to said joint part, and wherein said corresponding oscillating arm, in at least one leg of said U-shaped cross-section, is provided with at least one recess for receipt of a corresponding one of said at least one laterally extending protrusion, wherein each said at least one protrusion on each said joint part have different heights and each said at least one recess in each oscillating arm have different heights resulting in an asymmetric form of each said joint part and of each said oscillating arm with respect to their respective middle longitudinal planes, seen in vertical direction, in order to ensure that each windscreen wiper device can only be mounted on its corresponding oscillating arm.
