Definitions
- the present invention relates to a connection platform of a wiper blade for a motor vehicle. It also relates to a wiper blade comprising said connection platform and a wiper device comprising said wiper blade.
- the invention finds a particularly advantageous application, but not exclusive, in the field of wiper systems for motor vehicles.
- This type of windshield wiper is gradually replaced by a new generation of so-called flat blade wiper blades called "flat blade”, which have the particularity of no longer include a lifting beam structure.
- the flat wiper blades always include a flexible wiper blade, but with the difference that the outer armature responsible for supporting it is here replaced by a flexible structure directly integrated with the blade.
- the flat brushes comprise connection means for their connection to actuating arms of appropriate shape. It will be recalled in this regard that there are all kinds of actuating arms, such as hook arms, lateral pivot axis arms, longitudinal clipping arms, etc.
- connection means comprise, firstly, a connecting platform formed on the wiper blade, and, secondly, a connection connector to the actuating arm, intended to be assembled and locked on the connection platform.
- connection connector comprises two types of connection means, namely means for connecting the actuating arm to the connector either directly or indirectly by means of an intermediate adapter piece, and assembly means and locking connector on the connection platform.
- connection platform capable of receiving connectors adapted to various types of actuating arm on the same face of the platform. More specifically, the connection platform described in this document comprises, on the one hand, a stop for receiving a connector end, and, on the other hand, an elastic arm for locking the other end of the connector.
- connection platform requires the user to perform two successive movements, namely a first movement to bring one end of the connector against the stop of the platform , then a second pivoting movement of the connector around the stop so as to engage the other end of the connector in the resilient arm by clipping effect.
- the invention aims to provide an alternative to the known connection platform of the aforementioned international application that would simplify the maneuvers to perform to assemble and lock the connector on the platform.
- connection platform of a wiper blade for a motor vehicle for receiving a connection connector to an actuating arm, remarkable in that that said platform comprises locking means by reversible elastic deformation, able to lock the connector in a direction of insertion of said connector into the platform through an opening made on a side face of said platform.
- connection platform only one movement is necessary to assemble and lock the connector on the platform, that is to say a translational movement in said insertion direction.
- said locking means by reversible elastic deformation prevent the connector from performing a translational movement in the opposite direction to the insertion direction.
- said reversible elastic deformation locking means comprise an elastic blade having a locking stop of the connector in the platform and a slope for elastically disengaging said stop during the introduction of the connector through said opening.
- said elastic blade is cut in a wall of the platform, adjacent to said side face.
- connection platform further comprises a housing for a connection base of the connector to the platform.
- the function of the locking means by reversible elastic deformation, such as the elastic blade mentioned above, is then to maintain the connection base of the connector inside said housing.
- the invention also relates to a wiper blade, remarkable in it includes a connection platform according to the invention.
- the invention further relates to a wiper system, remarkable in that it comprises a wiper blade according to the invention and a connector connected to an actuating arm of a motorized mechanism wiping.
- Figure 1 is an exploded perspective view of a wiper system comprising a connection platform according to the invention.
- Figure 2a is a top view of the connection platform of Figure 1.
- Figure 2b is a sectional view along the line A-A of the connection platform of Figure 2a.
- Figures 3a to 3e are schematic side views illustrating the assembly and locking of a connecting connector on a connection platform according to the invention.
- connection platform 1 to be assembled on a wiper blade 2 for a motor vehicle comprising a wiper blade 2a, a flexible structure, also called vertebra, 2b and a aerodynamic deflector 2c.
- This platform 1 is particularly suitable for a wiper blade as known from the international application WO2006 / 069648.
- a connector 5 of connection is adapted to be connected directly or via an additional piece 8 to an actuating arm 10.
- the wiper blade 2, the connection platform 1, the connector 5 and the actuating arm 10 of a motorized wiper mechanism are part of a wiper system.
- windows of a motor vehicle such as the windshield or the rear window.
- Each type of actuator arm attachment such as hook arms, lateral pivot axis arms, longitudinal clipping / clipping arms, etc.
- a connector 5 carrying an element 52 is associated with a connector 5 carrying an element 52. specific connection to an actuating arm given, but each of these connectors fits the same platform 1 connection by a standard interface here constituted by the same base 51 connection.
- the connection element 52 of the connector 5 is constituted so as to be connected to a longitudinal latching actuating arm 10.
- the platform 1 connection comprises a housing 10 for the base 51 of the connector 5 connection 5.
- This housing 10 is limited by a bottom wall 11 of the platform 1 and by three so-called vertical walls 12, 13, 14, and finally three wall elements 12 ', 13', 14 'opposite said bottom wall 11 and forming an opening 16 intended to receive the connecting element 51 when the base 52 of the connector 5 is put in place inside the housing 10.
- the base 51 of the connection connector 5 connection is introduced into the housing 10 by performing a lateral translational movement in the direction indicated by the arrow 20.
- the side face 15 of the platform, opposite the vertical wall 13 has an opening 15 'whose dimensions are substantially equal to the corresponding lateral dimensions of the base 51 connection.
- the platform 1 of connection comprises locking means by reversible elastic deformation, able to lock the connector in the direction 20 of introduction of said connector 5 in the platform 1.
- these locking means are made by an elastic blade 30 which, as best shown in Figure 2a, is cut in the bottom wall 11 of the platform 1, adjacent at the lateral face 15, so as to allow it to deform elastically in a circular bending movement about the axis B.
- the elastic blade 30 further comprises a locking stop 31 of the connector 5 in the platform 1 and a slope 32 of retraction of the abutment 31.
- the platform 1 is made in a single piece of plastic material, preferably by injection.
- the connector 5 is presented in front of the platform 1 so as to place the connection base 51 opposite the opening 15 'of the housing 10.
- the connector 5 is introduced into the platform 1 in a translation movement parallel to the direction 20.
- the base 51 of connection exerts on the slope 32 of the elastic blade 30 a sufficient pressure force for causing the blade 30 to bend and the stop 31 to retract.
- the insertion movement then continues until the base 51 connection bears against the vertical wall 13. At this time, the connector 5 is in place in the platform 1.
- the connector lock 5 in this position is obtained because, the base 51 of connection no longer exerting force on the slope 32, the blade 30 is elastically released thereby causing the stop 31 in its nominal locking position of the connector 5, preventing the connection base 51 out of the housing 10 in a translation movement in a direction opposite to the insertion direction.
