Definitions

• the invention relates to a wiping system for a motor vehicle.
• the system generally comprises two windshield wipers which are driven in a rotary sweeping movement each alternated by a drive shaft, each shaft being guided in rotation by compared to the vehicle body in a guide bearing.
• the bearings are for example fixed on the body and they are connected together by a cross member which generally supports a geared motor assembly which ensures the rotational drive of the drive shafts.
• the bearing is produced for example by molding, in metallic material or in plastic material, and the cross-member is in principle produced in the form of a tube obtained in a conventional manner, by example by rolling.
• the object of the invention is to propose a new design of these systems which makes it possible to increase their rigidity, to reduce their weight and to increase the ease of production and assembly. of such a system.
• the invention first of all proposes a wiping system, characterized in that the cross-member is produced in the form of at least one extruded profile.
• the invention also provides a wiping system in which the guide bearing is produced in the form of at least one extruded profile.
• the cross member carries a motor which rotates the wipers
• the extruded profile is deformed by folding;
• the cross member is produced in the form of an assembly of several extruded profiles;
• the bearing is provided with holes for fixing it to the vehicle body using screws;
• two extruded sections are assembled by gluing;
• two extruded sections are assembled by welding;
• two extruded sections are assembled by riveting;
• the extruded profile is made of aluminum or aluminum alloy.
• Each wiper is intended to be mounted on a drive shaft (not shown) each of which is guided in rotation about the corresponding axis A1, A2 in a guide bearing 12 which is provided for this purpose with a bore 14.
• the two bearings 12 are intended to be fixed to the body of the vehicle, for example using fixing screws 16, and they are interconnected by a cross member 18.
• the bearings 12 are produced in the form of portions of an extruded profile, for example made of aluminum or an aluminum alloy.
• the bearing 12 includes a main core 20 in which is arranged, during the extrusion, the bore 14.
• the axis A1, A2 of the bore 14 is therefore directed in the direction of extrusion.
• the bearing 12 also comprises a lateral wing 20 which extends transversely with respect to the axis A1, A2 and in which holes 24 are made, for example by machining, to allow the passage of the fixing screws 16 of the bearing 12 on the vehicle body.
• the cross member 18 is produced from an extruded profile which has a U-shaped cross section.
• the cross member 18 can be fixed to each of the bearings 12, for example by gluing, by riveting, by welding or even by screwing.
• the cross-member 18 can be deformed by folding to adapt to the space constraints imposed as a function of the model of the vehicle on which the wiping system 10 is intended to be fixed.
• system 10 illustrated in the figure comprises a cross member 18 which is produced in two elements 26, 28, a second profile element 28 being bent and assembled on a first element
• the second element 28 of the crosspiece 18 thus has a first rectilinear part which is fixed by one end to one of the bearings 12 and which is extended at its other end by a part 32 bent substantially at 90 °, which is fixed, by example by gluing or welding, on the first element 26 of the cross member 18.
• the second element 28 therefore extends parallel to a straight section of the first element 26, so as to form a support plane for fixing a motor-reducer assembly 34 which is intended to drive the windscreen wipers in rotation.
• a motor-reducer assembly 34 which is intended to drive the windscreen wipers in rotation.
• the two elements 26, 28 of the crosspiece 18 are made from a U-shaped section which can easily be obtained in standard sizes commercially.
• the production of the crosspiece 18 no longer requires simple folding and assembly operations, the latter being able to be carried out very simply by gluing.
• such a design of the cross allows, starting from the same raw material consisting of the U-shaped section, to make cross 18 for different vehicle models. Indeed, it then suffices to adapt the length of the elements 26, 28 which are cut into an initial section of great length and to adapt the folding of these elements 26, 28 of the crosspiece 18 to allow the shape of the this to the vehicle on which the system 10 is installed.
• the profile from which the bearings 12 are made is relatively simple in shape and requires only a reduced number of machining operations.
• sectional shapes of the profiles used for the production of the system 10 may differ from those which are illustrated in the figures.
