Patent ID: 7979950

Claim:
A windscreen wiper device comprising: an elongated flexible carrier element having spaced-apart longitudinal strips, each of said strips including ends neighboring one another and interconnected by respective connecting pieces; an elongated wiper blade of a flexible material for placement in abutment with a windscreen to be wiped, said wiper blade including opposing longitudinal sides and a longitudinal groove in each of said longitudinal sides for receiving said spaced-apart longitudinal strips of said carrier element; an oscillating arm having an outer swinging end, and at least one shaped hole provided in said oscillating arm adjacent said end; a connecting device for pivotally connecting to said oscillating arm about a pivot axis near said end; a joint part interposed between said connecting device and said oscillating arm, said joint part including at least one resilient tongue shaped for engaging in said hole provided in said oscillating arm, said resilient tongue being rotatable about a hinge axis between an outward position retaining said wiper blade onto said oscillating arm and an inward position releasing said wiper blade from said oscillating arm; and characterized by said resilient tongue having a free end spaced between said hinge axis and said pivot axis and being closer to said hinge axis than to said pivot axis, said resilient tongue being configured to automatically move toward said outward position under influence of a moment resulting from a separation force exerted on said wiper blade in a longitudinal direction of said oscillating arm away from said end of said oscillating arm, whereby said resilient tongue actively resists disconnection from said oscillating arm in response to a separation force tending to pull said wiper blade away from said oscillating arm.
