摘要： An electro-mechanical actuator (1) including a plurality of motors (2, 3) for driving an output shaft (10). The actuator may be incorporated into a window lift mechanism (30), such as a mechanism including a dual rack and pinion assembly (1314). According to another aspect of the invention there is provided a variety of anti-back-drive mechanisms, e.g. clutches. A clutch according to one embodiment includes locking pawls (1616, 1618) that resist back-drive. In another embodiment, locking cams (2108) rotate relative to a carrier (2106) to resist back-drive. An actuator consistent with the invention may incorporate an impact mechanism (2616) including a flexible carrier (2618). The carrier (2106) flexes to prevent impact forces at an output gear train (2610, 2612) from coupling to an input gear train (2604, 2606).
