A cable tensioner for a vehicle window regulator includes a screw and nut assembly with an irreversible thread lead angle, a first spring designed to actuate the screw and nut assembly when there is slack in a cable and a second spring designed to block the screw and nut assembly when there is excessive tension in the cable. The cable tensioner ensures that compensation for the elongation of the cable is irreversible.

A process for monitoring the rotation of a DC electric motor, wherein the voltage and the intensity of the current supplying the motor are measured in a manner sampled over time and wherein, for each sampling instant tn, an estimate &thgr;n, of the angular position is calculated as a function of a determined or known position for a previous sampling instant and of an estimate of a value of angular speed between these two instants, which is dependent on the voltage and on the intensity of current measured for the sampling instant tn, and/or for one or more previous sampling instants.

In a window lifter of the cable type, comprising a motor for driving the cable bearing a slide (6) linked to a second slide (7) supporting the window, the two slides (6, 7) may be coupled via an elastic tension element (16) and one (6) of the slides is fitted with an electrical switch (17), associated with the second slide (7) so as to change state when the load on the slide (7) carrying the window (8) exceeds a predetermined value and when the elastic element (16) undergoes an extension corresponding to the separation between the slides; the switch (17) forms part of an electrical supply circuit for the motor, capable of reversing its direction of rotation when this switch (17) changes state, so as to free the movable member from an obstacle in its path. This electromechanical safety device has a simple structure and a low manufacturing cost.

Process for determination of the position of a door, window or roof of an automobile vehicle, according to which the angular position of the rotor of the electric motor actuating this door, window or roof is determined and the position of the door, window or roof is calculated as a function of the said angular position. The position of the door, window or roof is calculated by correcting a theoretical position that depends on the angular position by a term that takes account of the stiffness of the mechanical transmission between the door, window or roof and the electric motor, this term being a function of the motor power supply current. The device embodying this process is advantageously used in an electric window winder.

This device comprises mechanical link including a pawl (25) establishing a rigid drive link between a driving input member (2) and an output member (22), interacting with a prestressed element (31) which tends to hold the pawl in connection with the driving input member or with the driven output member, for so long as the force transmitted by the pawl remains below a predetermined value; this system automatically interrupts the kinematic drive chain of the movable member in the case of a force exceeding a predetermined value. This arrangement makes the device practically insensitive to friction and eliminates the uncertainty on the threshold of the triggering force.

A motor vehicle power-operated window lift, comprises a mechanism for driving the window, an electric motor (3), an anti-pinch system which can be triggered when there is an obstacle obstructing the window travel, and an electronic circuit for controlling the motor and the anti-pinch system. The window lift comprises a spring to reduce the pinch force when the window is being raised. In one example, the spring associated with a top sheath has a stiffness of about at least 10N/mm, and is fully compressed only in response to a compression force of about at least 250 Newtons. The spring constitutes a shock absorber in case of a strong impact, transforming it into a relatively mild impact, thereby providing more time for the electronic circuit controlling the anti-pinch system to intervene and reduce the pinch force.

A method and system for detecting the presence of an object caught between an automotive window and its respective frame includes an electric drive motor for opening and closing the automotive window. The electric drive motor receives power from a power supply via a primary brush assembly coupled to a power line. A piezoelectric sensor is mounted on the drive motor for sensing a resistive torque applied to the regulator and generating a signal having a value indicative of the resistive torque. The signal is then transmitted to a control circuit for determining whether or not an object is caught between the window and a frame based on the signal. The signal may be transmitted to the control circuit either by the primary brush assembly via the power line or by a secondary brush assembly coupled directly to the control circuit.
摘要:
A method and system for detecting the presence of an object caught between an automotive window and its respective frame is provided. The window opens and closes via a regulator driven by an electric drive motor. A force is sensed at an interface between the window and the regulator proportional to a force exerted on the window. This force is compared with a predetermined value, and if the sensed force exceeds the predetermined value, an object caught between the window and its respective door frame is detected.
