Abstract
The device comprises a detachable distance-piece (19') with a pivot (20) retained in a pivoting way in the yoke (7b) of a member (7) connecting a blade (4) to the hub, by one of the two blade pins (15) and a distance-piece yoke (22') in which the blade root (6) is retained pivoting by a fitting pin (18'). The blade (4) is folded by pivoting its root (6) with respect to the distance piece (19') and pivoting the latter with respect to the yoke (7b), with a lateral shift with respect to the conventional folding without a detachable distance-piece (19'), and with a fitting pin (18') which can be inclined with respect to the blade pin (15).
