ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention concerns an electric motor for actuating a functional unit of a motor vehicle. The invention is more particularly concerned with an electric motor of the type including a motor unit having at least one plastics material portion.
Electric motors of this type are used to drive functional units of motor vehicles such as adjustors for seats, windows, etc., for example. Such actuator motors are frequently associated with electronic circuits that supply power to the motors and monitor their operation to improve their safety.
For example, anti-pinching functions have been associated with gear motors for actuating vehicle window closing mechanisms in particular.
The increasing integration of electronic circuits into vehicles is also giving rise to a number of problems, in particular with regard to their location.
SUMMARY OF THE INVENTION
The aim of this invention is therefore to provide a motor of the above type that can easily be associated with electronic circuits.
To this end, the invention consists in an electric motor for actuating a functional unit of a motor vehicle, of the type including a motor unit comprising at least one plastics material portion. The motor unit includes a two-part casing for receiving at least one electronic circuit card. The casing preferably is formed of two complementary portions joining on a plane passing through a diagonal plane of the casing and provided with means for receiving the card and complementary fixing means. One portion of the casing is in one piece with the plastics material portion of the motor unit and the other portion of the casing includes an envelope for a connector for connecting the motor to the remainder of the circuits of the vehicle.
The invention will be better understood from the following description, which is given by way of example and with reference to the accompany drawings.
