In an electrically operated window actuating device in which power is normally transmitted from a motor to an operating cable through a reducing gear system, a manual emergency drive is provided in which a normally idling gear of the drive is mounted coaxially on the same shaft as the intermediate gear of the reducing gear system. Resilient means normally urge the driving gear of the emergency drive out of engagement with the idling gear. When the manual drive is put into operation, its driving gear actuates the idling gear and the intermediate gear of the reducing gear system thereby causing displacement of the operating cable. The housing for the apparatus is made up of symmetrical parts which can be reversed so as to fit both right and left hand side windows. |
