A central double drive unit for window winder systems in vehicles, that uses a forward kinematic chain (C1) and another second chain (C2) of the Bowden system. Both chains have the condition of unification of fast interchangeability for their drive. The central unit (A) is fixed to the rail support of the direct simplified forward chain and enabling rotation in relation to the said rail by a certain angle ( alpha , alpha '), either positively or negatively, in which the shafts of the unit (E,E') and of the drums (E1,E1')-(E2,E2') are parallel and contained in the same plane. The entry and exit point (13) of the cable on the drum (8) of the forward chain is situated on the bisecting line of the total angle ( alpha , alpha '), and at the diametrical most distant end from the wheel (6) in relation to the central shaft (E,E'). The central unit (A) has some lugs (10,27) in which bolts (12) are fitted and connected to some adjustment slots (11) cut in the support of the forward rail, so as to facilitate the turning of the unit. <IMAGE> |
