Patent number: 9097519Abstract: The object is to ensure the absence of friction between a housing supporting a sensor and a mounting arranged to support a target, and the absence of load take-up resulting from the contact and lack of precision among mounting interfaces. This involves forming, in a mounting position, a clearance between the mounting and the housing and then releasing the target mounting in the operative position of the sensor. A cylindrical recess for freely receiving with a clearance the mounting supporting the reference element serving as a target and which is mountable on the shaft, is provided in the housing which supports the sensor and which is attachable to the stationary part. Removable locking elements provided between the mounting and the housing maintain the latter in an initial position when the locking elements are operative and, when inoperative, release the mounting mounted on the rotary shaft from the housing.Type: GrantFiled: June 14, 2011Date of Patent: August 4, 2015Assignees: CONTINENTAL AUTOMOTIVE FRANCE, CONTINENTAL AUTOMOTIVE GMBHInventors: Michel Collet, Didier Puech, Xavier Bajul

Patent number: 8290664Abstract: A method and a device for measuring the angular position, between two steering locks, of a steering wheel of a vehicle, includes equipping the vehicle with a main gearing (4, 5) designed, once the vehicle has started, to make it possible to calculate the absolute angular position of the steering wheel from data provided by a first angular sensor (15) associated with this main gearing. According to the invention, the vehicle is additionally equipped with an auxiliary gearing composed of one of the gearwheels (5) of the main gearing, of a third gearwheel (8), and of intermediate elements (6, 7, 9) for sequentially driving the third gearwheel (8) that are able to make it possible, upon starting of the vehicle, to measure the angular position of the third gearwheel (8) via a second angular sensor (16) associated with this gearwheel.Type: GrantFiled: March 26, 2007Date of Patent: October 16, 2012Assignee: Continental Automotive FranceInventors: Michel Collet, Eric Servel, Yves Dordet

Patent number: 7880104Abstract: A control device for controlling electrical switchgear such as a circuit breaker or the like includes an actuating arm having a connection point suitable for being moved along a closed line including points P1, P2 and P3. The connection point thus moves during an opening stage for opening the moving contact, under the effect of a mechanical spring from point P1 to point P2. It also moves during a re-cocking stage for re-cocking the mechanical spring under the effect of a motor being switched on, and while keeping the moving contact in the open position, from point P2 to point P3. It also moves during a closure stage for closing the moving contact, also under the effect of the motor being switched on, from point P3 to P1. In this manner it is possible to successively perform three distinct stages of putting the actuating arm in motion, between the instant at which the moving contact leaves its closed position and the instant at which it returns thereto after having occupied its open position.Type: GrantFiled: December 19, 2006Date of Patent: February 1, 2011Assignee: Tour ArevaInventors: Wolfgang Grieshaber, Jean-Pierre Dupraz, Olivier Grejon, Alain Fanget, Xavier Allaire, Michel Collet

Patent number: 7331256Abstract: A pedal has a control device (2) including a mobile pedal (6), elements for returning (20, 22) the control device returning the pedal (6) in its idle position as well as a force-feedback mechanism (4) to produce a hard spot when the pedal (6) is depressed. The force-feedback mechanism (4) includes an electric motor (28) designed to act on the control device (2), via one-way linking elements (36) and gear reduction elements, in the same direction as the return elements (20, 22). The one-way link prevents any action of the force-feedback mechanism (4) on the control device (3) in the direction opposite to the direction of action of the return elements (20, 22) The one-way link advantageously includes a clearance which enables the electric motor (28) to rotate in the direction allowing it to act on the control device (2) without acting immediately on the device.Type: GrantFiled: December 2, 2002Date of Patent: February 19, 2008Assignee: Siemens Vdo AutomotiveInventors: Pierre-Yves Allard, Michel Collet, Gerard Mouaici, Wim Teulings
