Embodiment Construction
[0052] Referring to the drawings, a synchronization device according to the invention, in particular with at least two windscreen wipers, is indicated generally by reference numeral 10 in a first embodiment.
[0053] The device 10 includes at least two wipers 11 .
[0054] Each wiper 11 consists of a wiper blade 12 which is movably connected to an electric motor / gear motor 13 .
[0055] An electric motor / gear motor 13 drives the respective wiper blade 12 so that the blade oscillates between two predetermined positions, which are indicated by the letters A and B in FIG. 3 .
[0056] Furthermore, the device 10 comprises means 14 for activating / deactivating the gear motor 13 .
[0057] Also included are means 15 for signaling the travel and direction of travel of each blade 12 through a predetermined reference position, indicated by the letter C in FIG. 3 .
[0058] In addition to the devices already listed, a device 16 is provided for controlling the signal and actuating the a...

Abstract
A synchronization device particularly for at least two windshield wipers, comprising at least two wipers (11, 111), each of which is composed of a blade (12, 112) that is kinematically connected to an electric motor or gearmotor (13, 113) in order to oscillate between two preset positions (A, B); means (14) for activating / deactivating the gearmotor (13, 113); means (15, 115) for signaling the transit of each one of the blades (12, 112) through a preset reference position (C); means (16) for controlling the signals and driving the activation / deactivation means (14); the device further comprising: means (17) for determining the wiping time for each one of the wipers (11, 111); means (18) for calculating, in relation to the transit of the at least two wipers (11, 111) at the respective means (15) for signaling transit, the lead time error of the at least one wiper that is faster (11a, 111a) with respect to the slower wiper (11b, 111b) of the at least two wipers (11, 111); means (19) for calculating a correction time in order to reduce the lead error of each one of the at least one faster wiper (11a, 111a); means (19a) for identifying, at each wipe, the slower wiper (11b, 111b) and means (20, 120) for applying each one of the correction times to the corresponding motor / gearmotor (13, 113) of the at least one faster wiper (11a, 111a).
Description
technical field [0001] The invention relates to a synchronization device which is especially suitable for at least two windscreen wipers. Background technique [0002] Windshield wiper systems are used to improve the driver's visibility in all weather and climate conditions and are essential to any mode of transportation, from cars to vans, from airplanes to boats and the like. [0003] For larger vehicles, it is necessary to use a windscreen cleaning device having a plurality of blades, each for wiping a defined surface of the windscreen. [0004] On larger vessels it may comprise up to five or more blades. [0005] For these systems that contain at least two blades, most systems on the market use electric gear motors or motors to drive each blade. [0006] In these systems, each blade moves independently relative to the other blades when the motor / gear motor is activated. [0007] Soon after starting, the independent movement between the wiper blades becomes uncoordinat...
