Embodiment Construction

[0061] To facilitate clear understanding, in the remainder of the following description, elements that are common to different figures have the same reference numerals.

[0062] Such as image 3 , 4 As shown, the heating device according to the invention comprises a ridge 3 substantially in the shape of a longitudinal blade of rectangular cross section having two opposite longitudinal larger faces, namely an upper larger face 13 and a lower larger face 13 '. At the connection position of the ridge 3 to the body of the wiper 1, the upper larger face 13 is located on the convex side of the body 5 of the wiper blade 4 and the lower larger face 13' is located on the concave side of the body 5 of the wiper blade side.

[0063] The ridge 3 is made of a relatively hard material, such as steel, to transmit the pressure of the arm over the entire length of the wiper blade.

[0064] The heating element 3 on the upper surface 13 and the lower surface 13' of the ridge 3 results in a f...

Abstract

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.

Description

technical field [0001] The invention relates to a heating device for a windscreen wiper and to a windscreen wiper comprising such a heating device. [0002] The invention applies in particular to a heating device comprising a structural element such as a ridge carrying the heating element, which ridge is connected to a wiper blade of a windscreen wiper. Background technique [0003] A windshield wiper including a heating element may in particular be mounted to a vehicle to de-ice the blades in very cold weather and prevent the wiper from being iced to the windshield, and / or for spraying integrated into the wiper De-ice the branch pipe. [0004] Such as figure 1 with figure 2 As shown, the heated windshield wiper 1 in the prior art generally includes: [0005] • two ridges 3, in the form of blades, which support a shaped part 15, commonly called a "spoiler"; [0006] · two heating films 2 , including electrical resistance, each heating film 2 on one face of the respecti...
