- a bead 146b is provided under the head 146 of the base 140 of the main connection member 110 of the connection device 100 according to the invention.
- the protuberance 222 formed in the extension of the fourth upper wall 213 of the yoke 210 of the wiper arm 201 is inserted into the hole 101 delimited by the notch 146a formed in the head 146 of the base 140 of the main connection member 110 and it is understood from this figure 11 that this protuberance 222 engages with the bead 146b formed under this head 146, thus forming a first retaining zone 230 of the wiper arm 201 on the connection device 100 configured to limit the longitudinal movements of the wiper arm 201, that is to say the movements along the longitudinal axis L of the illustrated trihedron, in a first direction S 1 illustrated in figure 11.
- FIG 11 also makes visible the cooperation between one of the elastic tabs 154b of the removable part 150 of the main connection member 110 and one of the stops 221 provided on the fourth flanks 211 of the yoke 210 of the arm. wiper 201. As shown, it is more particularly a cooperation between an edge of the gripping zone 154c and the stop 221 formed on one of the fourth flanks 212 of the yoke 210 of the wiper arm. -glace 201.
- the removable part 150 of the main connection member 110 comprises the upper bridge 155 which connects the first side wall to the second side wall 154 of this removable part 150 and which participates in give the elastic tabs carried by this removable part 150 their elastic properties.
- this upper bridge 155 allows the two elastic tabs to be brought together towards each other, allowing, alternately, the engagement and disengagement of these elastic tabs, and more particularly the gripping areas of these elastic tabs, by compared to the stops 221 provided on the fourth flanks 212 of the yoke 210.
- this retractable button 144 comprises a retaining member 144a which, according to the illustrated example, takes the form of a rod which emerges from this retractable button 144, and which extends downwards.
- this retaining member 144a is adapted to come into abutment against the transverse wall 158 of the removable part 150 of the main connection member 110, and more particularly against a rear face of this transverse wall.
- this cooperation between the retaining member 144a of the retractable button 144 and the transverse wall 158 of the removable part 150 makes it possible to assist and strengthen the removable connection between the base 140 and the removable part 150 of the main connection member 110.
- this retaining member 144a forms a means of securing this removable connection between the base 140 and the removable part 150 of the main connection member 110, that is to say that in the event of breakage of this removable connection, the retaining member 144a guarantees that the wiper blade n e does not separate from the yoke 210 of the wiper arm.
- a projection member as well as the pipe making it possible to convey the windshield washer fluid to this projection member as described above can be attached to the wiper arm according to the third exemplary embodiment without the windshield wiper arm.
- connection device does not have to be changed.
- the elastic tabs of the removable part being engaged on the stops of the yoke of the wiper arm as has just been described, these elastic tabs do not interfere with driving, and the connection can thus be ensured by the connection device according to the fourth assembly mode.
- connection device intended to connect a wiper blade to a wiper arm which can be easily adapted for use with at least three types of wiper arm.
- different ice it being understood that the description which has just been given does not limit the scope of the present invention.
- other assembly methods not described here can be provided without departing from the context of the present invention, thus making it possible to adapt the connection device to a very large number of different wiper arms.
