Abstract
A rotary drive actuation system for actuating a latch including: an output shaft having a member affixed at one end of the output shaft for coupling to a component of the latch; a common drive element affixed to the output shaft at the other end of the output shaft; and a plurality of motors coupled to the common drive element for simultaneously driving the common drive element and the output shaft in a first rotary direction to effect actuation of the latch.
Claims21
An assembled power latch of a vehicle for mounting to a vehicle once assembled, the assembled power latch comprising:
- a latch frame having a first frame portion having a first mounting surface and a second frame portion having a second mounting surface, the second frame portion extending from the first frame portion, wherein the first frame portion is adjacent and integral with the second frame portion;
- a motorized actuation system mounted on the first mounting surface, the motorized actuation system having at least one motor with an output shaft having a longitudinal axis;
- a cinch cam coupled to the output shaft and configured to rotate about the longitudinal axis in a first direction and in a second direction opposite the first direction;
- a latch mounted on the second mounting surface and thereby adjacent to the motorized actuation system, the latch having a plurality of latch components including a cinch lever for operating the latch from a partially closed latch position to a fully closed and cinched position;
- and
- a linkage system including a cable extending between the cinch cam and the cinch lever, the cable coupling rotational movement of the cinch cam to movement of the cinch lever;
- wherein once mounted the latch and the motorized actuation system are in direct abutment and thus in direct contact with one another via the linkage system;
- wherein the latch frame of the assembled power latch is mounted to the vehicle once assembled, the vehicle including a vehicle body and closure panels of the vehicle.

A method for mounting of an assembled power latch to a vehicle, the method comprising:
- providing a latch frame having a first frame portion having a first mounting surface and a second frame portion having a second mounting surface, the second frame portion extending from the first frame portion, wherein the first frame portion is adjacent to and integral with the second frame portion;
- prior to said mounting of the assembled power latch to the vehicle, assembling the assembled power latch by:
- mounting a motorized actuation system on the first mounting surface, the motorized actuation system having at least one motor with an output shaft having a longitudinal axis, the output shaft having a cinch cam coupled to the output shaft and configured to rotate about the longitudinal axis in a first direction and in a second direction opposite the first direction;
- and
- mounting a latch on the second mounting surface to provide as adjacent to the motorized actuation system, the latch having a plurality of latch components including a cinch lever for operating the latch from a partially closed latch position to a fully closed and cinched position;
- and providing a linkage system including a cable extending between the cinch cam and the cinch lever, the cable coupling rotational movement of the cinch cam to movement of the cinch lever, such that once mounted the latch and the motorized actuation system are in direct abutment and thus in direct contact with one another via the linkage system;
- and
- providing said mounting of the assembled power latch by mounting the latch frame of the assembled power latch to the vehicle, the vehicle including a vehicle body and closure panels of the vehicle.
