<p>The invention concerns a window regulator (1) comprising an electric motor having a drive shaft (63), a window cursor (2), a transmission (5, 61, 62, 73) having an input (62) driven by the drive shaft (63), and an output (5) driving the cursor (2). The invention also concerns a gear motor (6) comprising a drive shaft (63), a reduction gear coupled to the drive shaft and having a transmission ratio less than 1, a piezoelectric element (68) selectively locking the drive shaft (63). The invention further concerns a method for operating said window regulator and said gear motor. The invention can be used to prevent fraudulent opening of the window. The invention can also be used to reduce the jamming force of an object between the window and the window frame.</p> |
