#CMT# #/CMT# The device has an angular position detection system for detecting angular positions of toothed input and output wheels (5, 6) that rotatably drive an opening frame of a vehicle i.e. motor vehicle. A reduction ratio between the wheels is chosen such that the angular positions of the wheels are identical between end positions such as completely closed and open positions, of the opening frame of the vehicle. The system has magnetic field detectors (11, 12) i.e. analog sensors, that detect magnetic fields emitted by respective magnets (7, 8). #CMT# : #/CMT# An independent claim is also included for a gear motor comprising an opening frame driving device. #CMT#USE : #/CMT# Device for driving an opening frame e.g. electrically or manually actuated rear hatch, of a vehicle i.e. motor vehicle, between end positions such as completely closed and open positions, and for use in a gear motor of the vehicle (all claimed). Can also be used for driving other opening frames such as electrically or manually actuated sliding door. #CMT#ADVANTAGE : #/CMT# The reduction ratio between the wheels is chosen such that the angular positions of the wheels are identical between end positions of the opening frame of the vehicle, thus determining an absolute position of the opening frame in a simple and precise manner, without knowing history of movement and without having a wheel that rotates around 360 degrees during a complete course of the opening frame between the positions, and hence assuring better functioning of an anti-pinch system. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic side sectional view of a part of an opening frame driving device. 5 : Toothed input wheel 6 : Toothed output wheel 7, 8 : Magnets 9, 10 : Rotational axes 11, 12 : Magnetic field detectors. |
