Connecting device for the articulated connection of a wiper blade to a wiper arm, and an adaptor

摘要

The invention is based on a connecting device (10) for the articulated connection of a wiper blade (11) to a wiper arm (24, 26, 28, 30, 32, 34), said connecting device having a connecting element (16) which is connected to a supporting element (22) of the wiper blade (11) for conjoint rotation and on which an adaptor (18) is mounted pivotably transversely with respect to the longitudinal direction thereof, said adaptor being able to be fastened releasably and for conjoint rotation to the free end of the wiper arm (24, 26, 28, 30, 32, 34) or to a joining element (36, 38, 40, 42, 44, 46) connected fixedly to the latter, wherein the adaptor (18) has a plurality of means (80, 96, 100, 102, 122, 126, 130, 134, 144) in order to be able to receive different joining elements (36, 38, 40, 42, 44, 46) of different wiper arms (24, 26, 28, 30, 32, 34), wherein the means include stop edges (86), spring latches (88), locking cams (100), spring clips (122) and spring tongues (128, 132) with latching cams (130, 134). It is proposed that the outsides of the side walls (90) of the adaptor (18) have locking cams (100) in the region of the driving end, wherein, in the fitted state, play-compensating ribs (64, 68) of a first or second joining element (36, 38) or of a covering cap (20) of the adaptor (18) engage under the locking cams (100) and bear on the end side against the steps (101) thereof while securing cams (66) which are arranged on the insides of the side walls (48, 108) of the first joining element (36), of the second joining element (38) or of the covering cap (20) in a manner offset in the longitudinal direction relative to the play-compensating ribs (64, 68) with respect to the driven end engage in installation gaps (96) in the side walls (90) of the adaptor (18), said installation gaps running transversely with respect to the play-compensating ribs (64, 68), and wherein, in the fitted state, the first joining element (36), the second joining element (38) or the covering cap (20) are clamped between the installation gaps (96) and a stop edge (86) by the front part (80) which is elastically flexible in the longitudinal direction, wherein the stop edge (86) is arranged at the transition of the front part (80) of the adaptor (18) to the driving part of the adaptor (18).
