Windscreen wiper device
A windscreen wiper device 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 to be wiped, which wiper blade includes at least one longitudinal groove, in which groove a longitudinal strip of the carrier element is disposed, which windscreen wiper device comprises a connecting device for an oscillating arm, wherein the oscillating arm can be pivotally connected to the connecting device about a pivot axis near one end, with the interposition of a joint part, with the special feature that the connecting device has a substantially H-shaped cross-section, wherein lower legs of the H-shaped cross-section are connected to the flexible material of the wiper blade on opposite sides thereof, and wherein upper legs of the H-shaped cross-section are adapted to receive the joint part.
1. A windscreen wiper device 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 to be wiped, which wiper blade includes at least one longitudinal groove, in which groove a longitudinal strip of the carrier element is disposed,
a connecting device for an oscillating arm which can be pivotally connected to said connecting device about a pivot axis near one end, with the interposition of a joint part,
wherein said connecting device is made as one integral and inseparable piece of a single material with a substantially H-shaped cross-section that has lower legs and upper legs,
wherein said lower legs are disposed in two longitudinally spaced apart sets and wherein said upper legs present a plurality of windows adjacent said lower legs,
wherein said lower legs of said H-shaped cross-section wrap around and directly contact a lower surface of the flexible material of said wiper blade on opposite sides thereof to connect the connecting device with the wiper blade,
wherein said upper legs present a pair of co-axially aligned and laterally outwardly extending protrusions which are cylindrically shaped,
wherein said cylindrical protrusions are positioned longitudinally between said windows and on solid wall portions of said upper legs for reinforcing said connecting device at said cylindrical protrusions,
wherein said joint part has outer walls disposed laterally outwardly of said upper legs of said connecting device,
wherein upper edges of said upper legs include chamfered areas adjacent a longitudinal front of said connecting device and adjacent a longitudinal back of said connecting device and wherein said joint part overlies said chamfered areas such that said chamfered areas increase a range of pivoting movement of said joint part relative to said connecting device,
wherein said protrusions are provided with co-axial through holes, and
further including at least one reinforcing rib made as one piece with one of said upper legs and being received in at least one notch provided in an outer circumference of the other of said upper legs for increasing the rigidity of said connecting device.
2. A windscreen wiper device according to claim 1 , wherein said at least one reinforcing rib and said at least one notch are provided in said chamfered areas of said upper edges of said upper legs.
3. A windscreen wiper device according to claim 1 wherein said at least one reinforcing rib is further defined as a pair of longitudinally spaced reinforcing ribs.
