1. A linkage device of the cross-wiss articulated type making it in particular possible to transform a substantially rectilingar alternating motion of a rod (1) into an alternating rotary motion of a spindle (2), for windscreens in particular, comprising two crossing cranks (4, 5), articulated at one of their ends to the rod (1) and at their other end to a companent (6) forming a lever fixed for rotation with the spindle (2), characterized in that at least one of the cranks (4) is made in the form of a stirrup in two elements (4a, 4b) substantially symmetrical in relation to the median plans (P) of this crank, and interspaced from each other along a direction perpendicular to this median plane and that the other crank (5) passes between the two elements (4a, 4b) of the first crank (4), the median plane of the second crank (5) being identical with that, (P), of the first (4). |
