A window lift system includes a motor drive assembly (10) constructed and arranged to control movement window glass of a vehicle, and a door module (35) to which the drive assembly is coupled. The door module has surface features (36) disrupting a surface (37) of the door module to reduce the transfer of vibration energy from the door module to the drive assembly or vise versa. In an embodiment, the door module includes a diaphragm (34) and the surface features are annular, undulating, wave-like features in the diaphragm.

What is claimed is: 1. A window lift system comprising: a motor drive assembly constructed and arranged to control movement of window glass of a vehicle, and a door module to which the motor drive assembly is coupled, the door module having surface features disrupting a surface of the door module to at least one of reduce the transfer of vibration energy from the door module to the motor drive assembly or reduce the transfer of vibration energy from the motor drive assembly to the door module, wherein the door module includes a diaphragm, the surface features being annular, undulating features in the diaphragm, and wherein the motor drive assembly is secured to the door module at fixing points, and a separate diaphragm surrounds each of the fixing points thereby defining a stiffness at the fixing points that is different from a stiffness of other portions of the door module. 2. The system of claim 1, wherein, in section, the surface features are generally in the form of a sine wave having peaks and valleys. 3. The system of claim 1, wherein the motor drive assembly has a rotatable shaft coupled with a worm gear. 4. The system of claim 3, wherein the worm gear is associated with an axle, the axle being constructed and arranged to cause movement of the window glass. 5. The system of claim 1, wherein the diaphragm is molded integrally with the door module. 6. A window lift system comprising: a motor drive assembly constructed and arranged to control movement of window glass of a vehicle, and a door module to which the motor drive assembly is coupled, the door module having means for disrupting a surface of the door module to at least one of reduce the transfer of vibration energy from the door module to the motor drive assembly or reduce the transfer of vibration energy from the motor drive assembly to the door module, wherein the means for disrupting includes a diaphragm having surface features including undulating features in the form of a sine wave having peaks and valleys in the diaphragm, and wherein the motor drive assembly is secured to the door module at fixing points, and a separate diaphragm surrounds each of the fixing points thereby defining a stiffness at the fixing points that is different from a stiffness of other portions of the door module. 7. The system of claim 6, wherein the motor drive assembly has a rotatable shaft coupled with a worm gear. 8. The system of claim 7, wherein the worm gear is associated with an axle, the axle being constructed and arranged to cause movement of the window glass. 9. The system of claim 6, wherein the diaphragm is molded integrally with the door module. 10. A method of reducing transfer of vibration energy from a door module to a motor drive assembly in a vehicle, the method comprising: providing a motor drive assembly constructed and arranged to control movement of window glass of a vehicle, mounting the motor drive assembly to a door module of the vehicle at fixing points, and providing surface features in the door module that disrupt a surface of the door module to at least one of reduce the transfer of vibration energy from the door module to the motor drive assembly or reduce the transfer of vibration energy from the motor drive assembly to the door module, wherein the step of providing the surface features includes providing at least one diaphragm, the surface features being annular, undulating features in the form of a sine wave having peaks and valleys in the diaphragm, a separate diaphragm surrounds each of the fixing points thereby defining a stiffness at the fixing points that is different from a stiffness of other portions of the door module. 11. The method of claim 10, wherein the step of providing the motor drive assembly includes providing the motor drive assembly to include a rotatable shaft coupled with a worm gear, the worm gear being associated with an axle, the axle being constructed and arranged to cause movement of the window glass. 12. The method of claim 10, wherein the diaphragm is molded integrally with the door module.
