    专利说明:

    [0001] The invention relates to a windscreen wiper blade comprising a heating element, in particular a flexible wiper blade or a flat windscreen wiper blade. A wiper blade has a scraper blade for cleaning a windshield of a motor vehicle.
    [0002] The scraper blade is carried by a support member. This support member contains an elongated vertebra element. The elongated vertebra member has a concave lower face to be turned towards the windshield of a vehicle to which the wiper blade is intended, and an upper face opposite to said concave lower face. Wiper blade heaters are known having a heating element integrated in the body of the wiper blade and extending generally along the length of the wiper blade.
    [0003] The heating element melts ice or snow that may form or clump on the wiper blade. Such a heating element is particularly useful for equipping wiper blades equipped with a washing liquid distribution ramp. In this case, the heating element makes it possible to heat the distribution ramp and in particular the distribution holes to allow the washing liquid to come out and wash the windshield of the vehicle to which the wiper blade is intended.
    [0004] When the heating element is in the form of a heating film or a heating coating, this heating element can be disposed by gluing or other adhesion means on the concave underside of the elongate vertebra element.
    [0005] WFR1859 2 However, this elongated vertebra member is inserted into the scraper blade support member. This heating element arrangement on the concave underside of the elongate vertebra element has several disadvantages. First, the thermal contact between the heating element and the support element made of flexible material may damage or degrade the flexible material of the support element, particularly in the case where this support element is a flat channel support member in full contact with the heating element. Then, in the case where the thermal loading of the heating film must be increased to obtain a better heat transfer efficiency, the risk of thermal degradation of the support element increases further. A first object of the invention is to overcome the drawbacks of the known state of the art, by proposing a new wiper blade heating allowing the use of a support member, while avoiding the risk of degradation thermal support element. A second object of the invention is to provide a new wiper blade heating, avoiding the risk of degradation of the support element by the heat emitted by the heating element.
    [0006] A third object of the invention is to allow a reduction of the power of the heating film, so as to minimize the risk of degradation of the support element.
    [0007] The subject of the invention is a windscreen wiper blade, in particular for a motor vehicle, comprising: a support element for a scraper blade; at least one elongate element forming a vertebra; at least one heating element in contact. with one side of the elongated vertebra element, characterized in that the wiper blade comprises spacer means arranged to prevent physical contact between the heating element and the support member. According to other alternative features of the invention: the heating element is in contact with the concave lower face of the elongated vertebra element. the spacing means is disposed between the elongate vertebra element and the support element. - The support element of the scraper blade has a housing at least partially surrounding the elongated member forming a vertebra. The spacing means may be provided by at least one shoulder of the support member, and preferably, two lateral shoulders on the support member to suppress or minimize thermal contact between the heating film and the support member, without impairing the good heat transfer between the heating element and the surfaces to be heated on the side of the support member. According to advantageous variants of the invention, the new heating device according to the invention is arranged with a flat channel support member, without lateral shoulders, and does not cause a decrease in the flexibility of the wiper blade, while avoiding the risk of degradation of the support element by the heat emitted by the heating element.
    [0008] According to other alternative features of these advantageous variants of the invention, the spacing means is distinct from the support element, thus: the spacing means is provided between the heating element and the support element; with flat channel and inside the flat channel housing at least partially surrounding the elongate vertebra element to prevent direct heat transfer between the heating element and the flat channel support member. the spacing means can be arranged on the concave lower face of the elongate vertebra element and separated from the heating element. The spacing means provided between the heating element and the support element flat channel can be arranged on the heating element. the spacing means provided between the heating element and the flat channel support element may be integrated with the heating element and comprise at least one non-heating, cold or thermally insulating part. - The spacing means provided on the side of the concave lower face of the elongate member may be constituted by at least one extra thickness of a sheath surrounding the elongate member forming a vertebra. The invention also relates to a heated wiper blade according to the particular invention, namely a wiper blade provided with a spray boom of a washing liquid.
    [0009] The invention will be better understood from the following description given by way of nonlimiting example, with reference to the accompanying drawings, in which: FIG. 1 schematically represents a perspective view of a first embodiment of a broom blade; wiper according to the invention connected to an actuating arm. FIG. 2 schematically represents a sectional view of the wiper blade according to the invention of FIG. 1. FIG. 3 schematically represents a sectional view of a second embodiment of a wiper blade according to the invention. the invention. Figure 4 schematically shows a sectional view of a third embodiment of wiper blade according to the invention. Figure 5 schematically shows a sectional view of a fourth embodiment of wiper blade according to the invention. With reference to FIGS. 1 to 5, identical or functionally equivalent elements are marked with identical reference numerals. In Figs. 1 and 2, a first embodiment of the wiper blade according to the invention, generally designated by reference (1), is advantageously WFR1859 5 a soft wiper blade or broom flat windscreen wiper with great flexibility. This flexible wiper blade (1) comprises a scraper blade (2), generally made of elastomer, for cleaning a windshield of a motor vehicle to which the wiper blade is intended. The scraper blade (2) elastomer is carried by a member (3) support. The support member (3) has two shoulders (3a, 3b) and contains an elongate vertebra element (4). A heating element (5) formed as a film or coating is disposed on the concave underside of the elongate vertebra element (4).
    [0010] A cover member (6) is attached to the snap-on support member (3). The covering element (6) may comprise a washing liquid spraying ramp (8) and / or an aerodynamic deflector (9) enabling the scraper blade (2) to be pressed against a window (not shown) of a non-conventional vehicle. represent.
    [0011] The invention also extends to any variant of the cover element with or without aerodynamic deflectors and with or without washing liquid spray ramps.
    [0012] The vertebra element (4) is inserted into a housing (7) formed inside the support element (3). The vertebra element (4) has on its upper face two electrical conductors (10, 11) for supplying the heating element (5) disposed on its concave underside. In other words, the electrical conductors (10, 11) are disposed on one face of the elongated member (4) forming a vertebra opposite the face receiving the heating element (5). WFR1859 6 Thanks to the shoulders (3a 3b), the heating film (5) is separated from the support member (3) so as to avoid thermal degradation of the support member (3) when the heating film (5) is electrically powered by the conductors (10 and 11). The presence of the shoulders (3a, 3b) slightly increases the rigidity of the support element (3), so that the plating on a vehicle window is less accentuated, particularly in the case of a curved windshield or high speed movements. It can be envisaged to remove the shoulders (3a, 3b) of the support member (3) to adopt a flat channel shape, having no internal shoulder, in order to maintain greater flexibility to the element (3). ) of support. The invention therefore also applies to support elements whose housing (7) has a flat channel structure, without any shoulder of the kind of shoulders (3a, 3b). This flat channel structure, without any shoulder, is similar to that of the support elements of the flexible wiper blades according to the invention having no heating element. In FIG. 3, a second embodiment of a wiper blade according to the invention comprises elements that are identical or functionally equivalent to the elements of FIGS. 1 and 2. The scraper blade (2), generally made of elastomer, is carried by a support element (3). The support member (3) contains an elongated vertebra element (4), and a heating element (5) formed as a film or coating is disposed on the concave underside of the elongated member (4). vertebrate. A cover member (6) is attached to the snap-on support member (3). The vertebra element (4) is inserted into a flat channel housing (7) formed within the support member (3). The vertebral member (4) has on its upper face two electrical conductors (10 and 11) for supplying the heating element (5) disposed on its concave underside.
    [0013] Spacing means (12) are provided and arranged on the concave underside of the vertebra element (4) to separate the heating element (5) from the inner face of the support member (3).
    [0014] These spacing means (12) are advantageously fixed under the concave lower face of the vertebra element (4) and are constituted for example in the form of flexible strips without contact with the heating element (5). By separating the spacer means (12) from the heating element (5), it is possible to use a flexible material, not necessarily resistant to the heat transmitted by the heating element (5) towards the element ( 3) support. In FIG. 4, a third embodiment of a wiper blade according to the invention comprises elements that are identical or functionally equivalent to the elements of FIG. 3. The scraper blade (2), generally made of elastomer, is carried by a support member (3).
    [0015] The support member (3) contains a vertebra member (4). A heating element (5) formed as a film or coating is disposed on the concave underside of the elongate vertebra element (4).
    [0016] A cover member (6) is attached to the snap-on support member (3). The vertebral member (4) is inserted into a flat channel housing (7) formed within the support member (3).
    [0017] WFR1859 8 The vertebra element (4) has on its upper face two electrical conductors (10 and 11) for supplying the heating element (5) disposed on its concave underside.
    [0018] Spacer means (13) provided on the heating element (5) are provided for separating the active portion of the heating film (5) from the support member (3). The spacing members (13) may be cold unheated edges of the heating element (5) in contact with the support member (3).
    [0019] Said spacing means (13) arranged on the heating element (5) can also be arranged on the heating element (5), forming thermally insulating lateral edges.
    [0020] Said spacing means (13) arranged on the heating element (5) can also be integrated with the heating element (5) and can be formed into edges having a low thermal transmission. In FIG. 5, a fourth embodiment of a wiper blade according to the invention comprises elements that are identical or functionally equivalent to the elements of FIG. 4. The scraper blade (2), generally made of elastomer, is carried by a support member (3). The support member (3) contains an elongate vertebra element (4). A heating element (5) formed as a film or coating is disposed on the concave underside of the elongate vertebra element (4).
    [0021] A cover member (6) is attached to the snap-on support member (3). The vertebral member (4) is inserted into a flat channel housing (7) formed within the support member (3). The vertebra element (4) has on its upper face two electrical conductors (10 and 11) for supplying the heating element (5) disposed on its concave underside.
    [0022] WFR1859 9 Spacing means (14a, 14b) are provided for separating the heating element (5) from the inner face of the support member (3). In the case where the vertebra element (4) is constituted in the form of a metal blade surrounded by a plastic coating, for example polyethylene terephthalate (PET), the spacing elements (14a, 14b) can advantageously consist of extra thicknesses of the polyethylene terephthalate (PET) envelope of the element (4) forming a vertebra.
    [0023] This arrangement allows the replacement of a vertebra (4) of the usual type by a vertebra (4) of lesser thickness surrounded by a polyethylene terephthalate coating having extra thicknesses. This arrangement thus makes it possible to standardize the manufacture of parts between wiper blades of the usual type and windscreen wiper blades according to the invention, because the dimensions of the other essential parts such as scraper blades (2), support element (3) and cover element (6) are not modified. This standardization thus allows the interchangeability of parts and a corresponding economy of stock.
    [0024] The invention described with reference to several particular embodiments is not in any way limited to them, but on the contrary covers any modification of form and any variant embodiment within the scope of the appended claims.
