Device connecting a wiper arm to a wiper blade, a wiper blade and a wiper arm
First Claim
1. Device to connecting a wiper arm to a wiper blade featuring a head strip and a supporting element on which a connecting element for the wiper arm is attached, wherein the supporting element comprises a strip received within a longitudinal groove of the head strip, and wherein the connecting element includes at least two holding means that cooperate with counter holding means connected to the wiper arm to connect the wiper arm to the connecting element, one of the at least two holding means including a first aperture defined in the connecting element shaped to receive a pin of the wiper arm in mating engagement, the connecting element further including a lever releasably engagable with a second aperture defined in the wiper arm, the lever having a locked state in which the lever is engaged with the second aperture and prevents release of the at least two holding means from the counter holding means, the lever also having an unlocked state in which the lever is disengaged from the second aperture to permit release of the at least two holding means from the counter holding means, wherein the wiper blade has a curvature in a relaxed state of the wiper blade to present a concave shape directed generally away from the connecting element, and wherein a base part is attached between the connecting element and the supporting element, the base part firmly connected to the supporting element to prevent relative movement between the base part and the supporting element, and connected to the connecting element so that the base part can rotate, the base part directly connected to the supporting element.

6. A windshield wiper assembly comprising:
-
a wiper arm; a wiper blade comprising a head strip; a supporting element comprising a strip received within a longitudinal groove in the head strip of the wiper blade; a connecting element attached to the supporting element, the connecting element including first and second apertures that each receive a respective portion of the wiper arm in mating engagement and cooperate to connect the wiper arm to the connecting element, at least one of the respective portions of the wiper arm comprising a pin, the connecting element further including a lever releasably engagable with a third aperture defined in the wiper arm, the lever having a locked state in which the lever is engaged with the third aperture and prevents release of the portions of the wiper arm from the first and second apertures, the lever also having an unlocked state in which the lever is disengaged from the third aperture to permit release of the portions of the wiper arm from the first and second apertures, the wiper blade having a curvature in a relaxed state of the wiper blade to present a concave shape directed generally away from the connecting element, wherein the wiper blade is connected to the wiper arm by a single base part attached between the connecting element and the supporting element, the base part firmly connected to the supporting element to prevent relative movement between the base part and the supporting element, and connected to the connecting element so that the base part can rotate, the base part directly connected to the supporting element. - View Dependent Claims (7, 8, 9, 10)

11. A windshield wiper assembly comprising:
-
a wiper arm including counter holding means; a wiper blade; a supporting element; a connecting element attached to the supporting element, the connecting element including a first and second holding means that cooperate with the counter holding means; and a base part attached between the connecting element and the supporting element, the base part firmly connected to the supporting element and connected to the connecting element so that the base part can rotate, the base part directly connected to the supporting element; wherein the connecting element is U-shaped with a U-base and two U-legs and accepts the base part;
wherein the first holding means features a guideway extending through the U-base into the U-legs;
wherein first articulation means are attached to the U-legs which cooperate with second articulation means attached to the base part;
wherein which can be engaged in holding means features a locking device in which at least one counter holding means so that it locks;
wherein the locking device can be locked independently and unlocked manually;
wherein the locking device is connected with at least one lever arm overlapping the supporting element; and
wherein the locking device features said lever arm corresponding to an opening in the wiper arm.
