Abstract
An actuator is provided to protect against pinching an object when closing powered automatic windows or sun roofs in motor vehicles in compliance with safety requirements. The displacement speed of the actuator is reduced as a function of the path location of the window or sun roof so that the total force including the stored kinetic energy of the entire drive system in the approach of the window or sun roof panel to an obstacle does not exceed the maximum allowed closing force.
