Problems solved by technology

[0013] However, such wipers do not provide a solution to the problem of possible damage to the gasket when wiping or when the wiper is transferred from or towards a storage position
[0014] Additionally, if the transfer includes retracting the arm prior to storing the scraper ( Figure 1c ), when it is retracted, the operation of the traditional bow-type hinged scraper results in the maintenance of both ends of the scraper in contact with the windshield, which may cause local damage to the windshield or damage to the scraper itself

Embodiment Construction

[0047] The invention is applied in the front part of the aircraft fuselage, at the windshield of the cockpit.

[0048] Such as image 3As can be seen above, in this non-limiting example, the windshield comprises two front panes 1 connected to the fuselage 2 by means of hoops and sealing gaskets 3 . exist figure 2 In the example shown, two front panes 1 are separated by a vertical strut 15 .

[0049] image 3 Mounted towards each of the front glass 1 is a wiper 4 shown above, while its function is to wipe the surface of said glass 1 by cyclic scraping, said wiper being driven by a motor of a type known to those skilled in the art and manipulation. For the two front panes forming the windshield, the two wipers 4 are arranged in a symmetrical manner, and as image 3 As seen above, the two wipers are stored in a rest position, which in this example is a vertical position next to the vertical support 15 .

[0050] For the following description, define: a longitudinal axis X,...

Abstract

Wiper blade for a surface of double curvature type, the said wiper blade including a flexible longitudinal wiper and means for exerting a bearing force at at least one point of the said wiper along a direction Z mainly normal to the surface, also including a longitudinal part, attached to the wiper at several points, and means to vary over time and in at least one segment of the longitudinal rod the rigidity in bending of this longitudinal rod in a plane XZ normal to the surface between previously chosen values. The longitudinal part is a metallic blade where the inertias on the two axes of its section are very different.

Description

technical field [0001] The present invention belongs to the field of scrapers, more particularly scrapers for aircraft. Background technique [0002] In the field of aviation, in order to allow the pilot to observe the external environment of the aircraft, the cockpit is equipped with different glazing, in particular with one or several front glazings forming a windshield. These front panes have hitherto generally been planar in shape and their aerodynamic continuity on their perimeter relative to the fuselage is ensured by a sealing gasket, the number of these front panes being generally two in commercial aircraft. [0003] When it rains, the run of water on the front glass, and the collision of insects can hinder the driver's good vision, especially during take-off and landing. Thus, wipers are mounted on the outer surfaces of these front glasses. The operation of the wiper is known: it scrapes circularly on the glass by means of a wiper which is substantially perpendicu...
