Abstract

A latch actuator comprises a motor, a speed reduction gearing coupled to an output shaft of the motor, a spindle, and a motion conversion mechanism. The spindle has a threaded portion in engagement with the speed reduction gearing. The spindle is supported to be rotatable about an axis. The threaded portion is rotationally fixed relative to the spindle. The motion conversion mechanism is configured to cause a displacement of the spindle along the axis when the spindle rotates.
