The object of the invention is to provide a pivoting arm which remains free of dust internally and can emit neither lubricant nor abrading particles. …<??>This object is achieved by means of a single, hollow, main cylindrical crossbar (12), essentially sealed on all sides, as a spring housing and a second connecting rod (84) between the rod end (68) close to a spring support (88) fixed to the rod and the adjacent support stud (18), the two connecting rods (62 and 84) being arranged continuously parallel in the housing (12). …<??>The advantage of this solution is the encapsulation of all the pivoting arm parts up to the two support studs, which are easily sealed with respect to the transverse spring housing (12). …<IMAGE>… |
