<p>An electric power window device for motor vehicles, particularly but not exclusively for motor vehicles of the armored type, of the type which comprises a guide (11) to be arranged substantially vertically within the body of the vehicle and a slider (12, 112) which is arranged so that it can slide on the guide (11) and to which the window pane to be moved can be fixed. The slider (12, 112) is connected to a rotary actuation element (13) by means of an upper portion (15, 115) and a lower portion (16, 116) of a flexible transmission element (14, 114). The upper portion (15) of the flexible element (14, 114) comprises a first upper part (22), which extends from the rotary actuation element (13) toward an upper guiding element (23) arranged above the slider (12, 112), and a second upper part (30), which extends from the first guiding element (23) toward the slider (12, 112). Likewise, the lower portion (16, 116) of the flexible element (14, 114) comprises a first lower part (26) which extends from the rotary actuation element (13) toward a lower guiding element (27) arranged below the slider (12, 112) and a second lower part (31) which extends from the second guiding element (27) toward the slider (12, 112). The device comprises, on the slider (12, 112), at least one pulley (32, 132) for guiding respectively the second upper part (30) and the second lower part (31) respectively toward a first region (33), which is arranged substantially above the position occupied by the at least one pulley (32, 132) when the slider (12, 112) is at the upper stroke limit of the guide (11), and a second region (34), which is arranged substantially below the position occupied by the at least one pulley (32, 132) when the slider (12, 112) is at the lower stroke limit (11b) of the guide (11).</p> |
