    "Installation for measuring the application force distribution of a wiper blade against a surface to be wiped"
    Field of the invention
    The present invention relates to a me¬sure installation to grasp the distribution of the application force of an ice-esque broom supported by a force against a surface.
    The invention also relates to a method for implementing such an installation.
    State of the art
    The force of application of the wiper blade against the window of the vehicle or windshield as well as the distribution of the application force over the length of the wiper blade are particularly important for the quality of wiping. a vehicle windscreen wiper.
    DE 100 44 172 A1 discloses a measuring device for detecting the application force distribution of a windscreen wiper or wiper blade support member pressing a surface. The measuring device is intended, in particular, for flat wiper blade support elements in the form of elastic webs or stiffeners housed in the lateral grooves of the rubber profile of the windscreen wiper blade or in a longitudinal longitudinal channel of the rubber profile. . These support elements are precin¬trés so that the action of the application force of a wiper arm, applies them with an appropriate force distribution against the windshield.
    For support of the support element, the me¬sure installation comprises a support rail with a longitudinal slot. A detection head equipped with a force measuring device is movable in the longitudinal direction of this slot. During the measurement operation, the detection head detects the application force exerted at each measuring point in the longitudinal direction of the sup¬port element during the course of the detection head. From the forces of application captured by this operation, the distribution of the application force is determined as a function of the length of the support element. If the distribution of the application force should not have the desired values, one could intervene on the bending process. In addition, the measuring installation can be used to monitor mass-produced support elements. For the exploitation of the measurement values, these are supplied to a computer equipped with a display.
    The force with which the support member is pushed against the support rails can be varied and adjusted according to the type of support element. In the simplest way, this is done with a folding wiper arm creating conditions close to reality. The possibility of folding the windscreen wiper arm allows simple manipulation of the measuring installation and in particular the support of the support element on the support rail.
    Description and advantages of the invention
    The present invention relates to a me¬sure installation of the type defined above, characterized in that the wiper blade comprises a coupling element which connects arti¬culée manner to a receiving device which applies a substantially perpendicular to the surface, and a measuring apparatus comprises a set of measuring sensors disposed in the longitudinal direction of the wiper blade, and forming a convexly curved surface in the longitudinal direction of the wiper blade for the support of the wiper blade during the measuring operation, the radius of cur¬sure of these surfaces being equal to 3000 or 4000 mm or corresponding to the curvature of an existing vehicle windshield, which is intended windscreen wiper, and the meter is connected to an operating unit.
    In other words, the wiper blade comprises a coupling element which connects it articulately to a receiving device for applying a force substantially perpendicular to the surface. A measuring apparatus comprises a set of measuring sensors installed in the longitudinal direction of the windshield wiper and forming a convexly curved surface in the longitudinal direction of the wiper blade to act as a support for the wiper blade. during the measuring operation. The radius of curvature R of the surface is of the order of 3000 or 4000 mm or still corresponds to the curvature of a window or windshield of a real vehicle, for which the windscreen wiper blade is intended. The meter and its sensors are connected to an operating unit such as a computer. General, for the precision it is enough to use radii of curvature of 3000 mm or 4000 mm because these curvatures are representative of the usual vi¬tres of vehicles. However, for large series, it is possible to adapt the radii of curvature to the curvature of a real vehicle windshield.
    A display shows the values obtained. At the same time, the values are available for manufacturing windscreen wiper blades, particularly for the bending installation of the sup¬port elements and the elastic rails or stiffeners. In addition, statistical operations can be carried out. The simultaneous entry of many measured values distributed along the length of the wiper blade accelerates the measurement operation. In addition all the important factors which in¬fluence the distribution of the force of application will be taken into account, for example the shape and the material of the wiper blade or deflec¬teur.
    According to a development of the invention, the surface formed by the measuring sensors has a convex curvature in the longitudinal direction of the wiper blade. The curvature is chosen to be adapted to the curvature of a vehicle windshield corresponding to a certain application.
    So that during the measurement operation the lip of the wiper blade always take the same defined position namely a tilted position as for the wiping operation of the windshield, a support piece follows the surface of measurement sensors, transverse to the longitudinal direction of the wiper blade and being level with this surface formed by the measuring sensors. The sur¬face thus formed and the wiper blade are advantageously sliding in the direction transverse to the longitudinal direction of the wiper blade. During the operation of the me¬sure installation, the wiper blade is applied to the application force set on the support piece, then the measuring device and the transverse wiper blade are moved transversely in the longitudinal direction of the windscreen wiper in a relative motion until the wiper blade is applied by its lip to the measuring sensors. In the case of a relative movement, the wiping lip tilts in the desired tilting position, which creates perfect, reproducible measurement conditions.
    The relative movement can be obtained simply by installing the measuring apparatus on a movable support transverse to the longitudinal direction of the wiper blade while the wiper blade is fixedly supported against a support through a wiper arm. The support can be controlled electronically or electronically by a suitable training facility.
    Another possibility is to bring the receiving device frame of the wiper blade acting on the coupling element of the wiper blade and which can be brought closer to the surface per¬pendicularly by means of a wiper blade. application of a force.This means for applying a force is electronically controlled. The application force of a force receives its signals for the force to be adjusted and for the reciprocating movement of an electronic operating unit which allows a very fast adaptation to each windscreen wiper or type of windscreen wiper. measure. The device for receiving the wiper blade is also adapted to the coupling element of the corresponding type of wiper. To use the correct receiving device for each type of wiper blade, the receiving device frame has an electronic probe that verifies the adjustment correction.
    It may be advantageous for this installation to use instead of a mobile support for the measuring apparatus, a receiving device and / or a force-applying means with the receiving device transversely to the longitudinal direction. The windscreen wiper blade in the direction of approach to perform the relative movement between the measuring apparatus and the ice-shield broom.
