A heated wiper blade for motor vehicles includes an elongated flexible beam and a heating element extending along the beam. The heating element may be configured to provide increased heat at the central portion of the blade and at the opposite ends of the blade. The heating element is comprised of an electrical conductor material that varies the amperage drawn between hot and cold ambient temperature operation. The flexible beam may include curved end portions and a flat or reduced curvature central portion. The heating element is preferably covered and sealed off to prevent loss of heat energy.

A heated wiper assembly has a frame for attachment to a windshield wiper arm of a vehicle and a resilient wiper body on the frame. A cover is mounted to the frame along opposing side edges and includes an apex which is raised relative to the side edges of the cover member to define at least one ramped and air deflecting surface and a hollow passage along the cover. A heating element received in the wiper body includes electrical leads extending through the hollow passage in the cover. A controller of the heating element is supported externally of the cover member. The conductive wires of the heating element are received within a common injection molded sheath. A wiring adapter is mounted in place of a fuse within a vehicle fuse box and includes circuits for ready connection of the heating element to a power source of the vehicle.

The invention relates to a wiper arm (10) for a windscreen wiper system of a motor vehicle, with a receiving region (11) for a wiper blade adapter (55) consisting of several wiper blade adapter elements (56; 56a, 57; 57a, 58), wherein the wiper arm (10) has a securing element (65; 65a) which at least partially covers the receiving region (11), wherein the securing element (65; 65a) is constructed such that it is movable between a dismantling position, in which the wiper blade adapter (55) is removed from the receiving region (11), and a locking position, in which the wiper blade adapter (55) is held in the receiving region (11), wherein an adapter element (75) serving to supply washing fluid and/or to supply power is arranged in the receiving region (11), and wherein the adapter element (75), on the one hand, can be connected to a supply line for the washing fluid and/or to an electric line (79) and, on the other hand, has an outlet (77) for the washing fluid and/or a plug connection (78) for the electric line (79), wherein the outlet (77) and/or the plug connection (78) can be connected to a first wiper blade adapter element (56; 56a).

The invention proposes a wiper blade (10) of a motor vehicle, comprising a heating electrical circuit (30) comprising at least one heating resistive element, which is connected to terminals (36) for supplying electric current, and a component for regulating the electric power supply current, which is a resettable fuse with a positive temperature coefficient (50), known as a PTC fuse. The PTC fuse (50) is, for example, a surface-mounted component, known as a CMS component, which is electrically connected to two belonging electrical connecting areas (44, 46).

The invention relates to a motor vehicle wiper system comprising: at least two windscreen wipers 12, 22, including a first windscreen wiper 12 and a second windscreen wiper 22, a heating device comprising a first heating element 14 designed to heat the first windscreen wiper 12 and a second heating element 24 designed to heat the second windscreen wiper 22, an electrical supply device designed to supply electricity to the first 14 and second 24 heating elements, and a control module,
the wiper system being characterized in that the control module is designed so as to delay, when the heating device is activated, the electricity supply to the second heating element 24 compared to the electricity supply to the first heating element 14, by a pause duration t.

Connector for retaining a wiper (3) on a windscreen wiper arm, including an internal electrical connection device between, on the one hand, an electrical connector connected to the electrical circuit of the vehicle and, on the other hand, at least one heating element (11) deposited on a reinforcement (20) implanted in said wiper, characterized in that said internal connecting device includes at least one metal part (10) extending perpendicularly to the heating element (11) and exerting pressure against it so as to ensure a permanent contact with said heating element (11).

Heating device including at least one vertebra (3) adapted to be mounted longitudinally in at least one housing of a windscreen wiper, the so-called upper face (13) of the vertebra (3) facing the actuator arm in the assembled position of the wiper and the actuator arm and at least one heating element (2) a first portion (14) of which is on the upper face (13) of the vertebra (3). A second portion (14) of the heating element (2) is on the lower face (13) of the vertebra (3), opposite the upper face (13), the first and second portions (14, 14) of the heating element (2) on the upper face (13) and the lower face (13) of the vertebra (3) being in electrical contact with each other.
