Heated wiper device for a vehicle, in particular for a snowgroomer, the wiper device comprising: a wiper blade configured for being springily against the windscreen's outer surface of the vehicle; a wiper blade carrier; wherein the wiper blade carrier supports and at least partially houses the wiper blade; a box supporting and at least partially housing the wiper blade carrier; a wiper arm comprising a first end coupled to the box and a second end configured for being rotatably coupled to the vehicle to enable the wiper blade to move on the windscreen; and an electrical heating device coupled to the box in a position such that the electrical heating device is facing the wiper blade carrier.

The invention concerns a rear view system (1) of a motor vehicle comprising:—an optical image capturing sensor (3),—a protective support (5) comprising a transparent and flat protective screen (7), the optical sensor (3) being installed on the protective support (5) in such a way as to point through said protective screen (7), and—a scraper blade (9) for cleaning the protective screen (7) disposed on the face of the protective screen (7) opposite that of the optical sensor (3) side, characterised in that it further comprises an electromagnetic actuation device (11) for actuating said scraper blade (9) in translation on the protective screen (7).

A wiper blade (10), in particular for a motor vehicle. Said wiper blade comprises a wiper strip (12) and a heating element (32). The heating element (32) is designed to be self-regulating.

A heated windshield wiper system includes a vehicle has a wiper motor and a windshield. The wiper motor is electrically coupled to the vehicle. A pair of windshield wipers is provided and each of the windshield wipers is movably coupled to the vehicle. Each of the windshield wipers is operationally coupled to the wiper motor. The wiper motor selectively urges each of the windshield wipers across the windshield. Thus, each of the windshield wipers may clear the windshield. A heating unit is coupled to each of the windshield wipers. The heating unit is electrically coupled to the wiper motor. The heating unit selectively heats each of the windshield wipers. Thus, each of the windshield wipers may melt snow and ice from the windshield.

Assembly for the production of a wiping system (1), comprising a terminal part (4) of a wiper arm (3) designed to move a wiper blade (2), and a connecting interface (5) for conveying a liquid to the wiper blade (2), said assembly further comprising one sliding element (6) having a first position for locking a connecting device of the wiper blade (2) on said terminal part (4), and a second position enabling the terminal part (4) and the connecting device to be separated, said sliding element (6) being further able to hang said connecting interface (5) either on the connecting device in the first position or on the terminal part (4) in the second position.

This disclosure details motor vehicle wiper systems and associated methods for heating wiper blades of the wiper systems. In exemplary embodiments, a wiper blade of a wiper may include a beam blade portion, a tip portion, and a heater element. Each of the beam blade portion, the tip portion, and the heater element may include a different material composition. The material composition of the heater element, for example, may include a thermally conductive polymer. The temperature of the blade may be regulated by adjusting a current flow through the thermally conductive polymer heater element.

A heated wiper system includes a wiper blade with a resilient wiper element having a passage along the wiper element from an opening at one end of where a heating element is inserted into the passage. The temperature of the heating element is controlled by controlling the current supplied to the element by a control unit contained either in the engine compartment or in a recess on the wiper blade. The control unit uses an algorithm including wiper blade and outside ambient temperature, wind chill, ignition on, motor running, heating element resistance value and wipers and varies the current supplied in dependence on a value of the resistance of the heating element.

The invention proposes a heating element (30) incorporating an electric heating circuit for a windscreen wiper blade on a motor vehicle, comprising at least one resistive heating element (36) which is connected to the electric power supply terminals (40) of said heating element, characterized in that at least one resistive heating element is a PTC resistive heating element (36), formed by the application of a resistive ink with a positive temperature coefficient.

Screen wiper blade of a vehicle, in particular a motor vehicle, comprising a heating electrical circuit, characterized in that said circuit comprises at least one bimetal strip thermostat configured to provide a thermal fuse function.

Windscreen wiper heating element for a vehicle, in particular a motor vehicle, including an electrical heating conductor circuit (120) and a support (118) of that circuit, the circuit including at least one loop (122) the ends of which are connected to electrical power supply terminals (126, 128) characterized in that said at least one loop includes at least one fusible portion (F1, F2) in which the section and/or the material of the conductor of that loop is different from that or those of the conductor of the rest of the loop.
