Connection module for windshield wiper blade and wiper system

Abstract

The invention relates to a connection module (4) for coupling a wiper blade (1) to a drive arm (2) of a wiping system (5), the connection module (4) comprising a connector (14) through which a conduit (143) extends, and a fixing member (3) of the drive arm (2) on the connector (14), the fixing member (3) comprising a shaft (32) extending through the conduit (143) of the connector (14), so as to axially lock the drive arm (2) mounted on the connector (14) while allowing its rotation around the shaft (32). The invention also relates to a wiping system (5) comprising such a connection module (4) and a drive arm (2) having a yoke (21) fitted onto the connector (14), the shaft (32) of the fastening member (3) extending through an opening (213) formed on a first lateral edge (211) of the yoke (21).

Claims

Claims

1. Connection module (4) for coupling a windscreen wiper blade (1) to a drive arm (2) of a wiping system (5) for a motor vehicle, the connection module (4) comprising: - a connector (14) secured to a scraper blade (13) of the windscreen wiper blade (1), the connector (14) extending along a specific elongation axis (X) and comprising, relative to a transverse axis (Y) perpendicular to the specific elongation axis (X);- a fixing member (3) for fixing the drive arm (2) to the connector (14), the fixing member (3) comprising a shaft (32) delimited by a first axial end (33) and a second axial end (34), the first axial end (33) comprising a support flange (31) configured to bear against the drive arm (2), the shaft (32) being configured to extend between a first lateral flank (141) and a second lateral flank (142) of the connector (14), so as to axially block the drive arm (2) mounted on the connector (14), relative to the proper elongation axis (X).;

2. Wiping system (5) for a motor vehicle, the wiping system (5) comprising: - the connection module (4) according to the preceding claim; - a drive arm (2) extending along the proper elongation axis (X) and comprising, at an axial end, a yoke (21) comprising a first lateral edge (211), a second lateral edge (212) and an orifice (213) formed on at least one of the lateral edges (211, 212), the yoke (21) being configured to encase the connector (14) of the connection module (4), the shaft (32) of the fixing member (3) of the connection module (4) extending through the orifice (213) of the first lateral edge (211) of the yoke (21).

3. Wiping system (5) according to the preceding claim, in which the shaft (32) of the fixing member (3) extends through a conduit (143) of the connector (14) from its first lateral flank (141).

4. Wiping system (5) according to the preceding claim, in which the shaft (32) of the fixing member (3) opens at the level of the second lateral flank (142) of the connector (14).

5. Wiping system (5) according to the preceding claim, in which the shaft (32) of the fixing member (3) opens at the level of the second lateral edge (212) of the yoke (21) of the drive arm (2).

6. Wiping system (5) according to any one of claims 2 to 5, in which the support flange (31) of the fixing member (3) bears against the first lateral edge (211) of the yoke (21) of the drive arm (2).

7. A wiping system (5) according to any one of claims 2 to 6, wherein the fixing member (3) comprises an axial locking element (35) configured to axially lock the fixing member (3).

8. Wiping system (5) according to the preceding claim, in which the axial locking element (35) comprises at least one lug which extends radially from the shaft (32), the orifice (213) of the first lateral edge (211) of the yoke (21) comprising a complementary notch (214) configured to allow the passage of the lug.

9. Wiping system (5) according to the preceding claim, in which, relative to the transverse axis (Y), the first lateral edge (211) of the yoke (21) is located in an intermediate position between the axial locking element (35) of the fixing member (3) and the support flange (31) of said fixing member (3).

10. Wiping system (5) according to the preceding claim, in which the axial locking element (35) is located at a distance from the support flange (31), so that said distance is greater than a thickness of the first lateral edge (211) of the yoke (21), taken relative to the transverse axis (Y).
