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 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 device comprises a connecting device for an oscillating arm, wherein the oscillating arm is pivotally connected to the connecting device about a pivot axis near one end, with the special feature that the connecting device comprises at least two parts provided with protrusion/hole features for detachably connecting the parts together, wherein the first part is retained onto the wiper blade and wherein the second part has an at least substantially U-shaped cross-section at the location of its connection to said first part, wherein each leg of said U-shaped cross-section is allowed to bend outwardly upon insertion of the oscillating arm into said second part for connecting said first and second parts together through a snapping operation.
1. A wiper blade assembly, comprising:
an elongated wiper blade of a flexible material;
a carrier element biasing said wiper blade into a pre-curved condition;
a connecting device including first and second parts detachably coupled with one another through a protrusion and hole connection, said protrusion and hole connection having a connected position, wherein a protrusion is received in a hole, and a disconnected position, wherein said protrusion is removed from said hole;
said first part being operably coupled to said wiper blade; and
said second part having a generally U-shaped cross-section at the location of said protrusion and hole connection between said first and second parts and wherein each leg of said U-shaped cross-section is automatically bent outwardly to move said protrusion and hole connection from said disconnected position to said connected position in response to insertion of an oscillating arm into the location of said U-shaped cross-section of said second part to interconnect said first and second parts.
2. The wiper blade assembly according to claim 1 , wherein said protrusion and hole connection automatically returns to said disconnected position and said first and second parts are released from each other in response to removal of the oscillating arm from said second part.
3. The wiper blade assembly according to claim 1 , wherein said first part is provided with opposite abutting surfaces for abutting against the legs of said U-shaped cross-section, and wherein a protrusion extends laterally outwardly from each leg of said U-shaped cross-section into a hole provided on an abutting surface abutting against a respective leg.
4. The wiper blade assembly according to claim 1 , wherein said second part is positioned at least substantially within said first part.
5. The wiper blade assembly according to claim 1 , wherein said carrier element includes a pair of longitudinal strips.
6. The wiper blade assembly according to claim 5 , wherein said longitudinal strips of said carrier element are disposed in opposing longitudinal grooves on longitudinal sides of said wiper blade.
7. A wiper blade assembly, comprising:
an elongated wiper blade of a flexible material;
a carrier element biasing said wiper blade into a pre-curved condition;
a connecting device including first and second parts detachably coupled with one another through a protrusion and hole connection;
said first part being operably coupled to said wiper blade;
an oscillating arm; and
said second part having a pair of laterally spaced legs and a wall interconnecting said legs to define a generally U-shaped cross-section at the location of said protrusion and hole connection between said first and second parts and wherein said legs receive said oscillating arm therebetween within the location of said protrusion and hole connection, whereupon insertion of said oscillating arm between said legs causes said protrusion and hole connection to move from a disconnected position to a connected position.
