Embodiment Construction

[0026] In the usual manner in the field, the wiper blade for a windshield wiper is an elongated member obtained by molding or extruding a plastic material such as rubber. The main features of the wiper are shown in its cross-section, and only the cross-section of the wiper will be described below.

[0027] figure 1 Shown with the general reference number 1 is a wiper, which comprises a fixed base 2 of a wiper 3 fixed to the windshield through grooves 21 and 22, connected to the base 2 by a hollow flexible hinge portion 5 Wiping lip 4, the hollow flexible hinged part 5 comprises two curved flexible walls 6 and 7 substantially symmetrical with respect to the plane of symmetry P of the section of the wiper. An inner stop 8 arranged inside a hollow area 9 inside the flexible hinge part 5 is connected to the base 2 via a flexible central part 10 . On both sides of the wiping lip 4, the means 11 and 12 constituting an external stop are designed to be connected to the curved flexib...

Abstract

The invention relates to a wiper blade for a vehicle window wiper, comprising an articulated part. Said wiper blade (1) for window wipers of motor vehicles comprises a heel (2) for fixing to a window wiper (3), a wiper lip (4), a flexible articulated part (5) connecting the lip to the heel - the lip extending along a central axial plane (P) of the blade, and the articulated part comprising two bent flexible partitions (6, 7) which are essentially mutually symmetrical in relation to said plane and define a recess (9) with the heel - and an inner abutment (8) which projects from the heel into the recess, is essentially symmetrical in relation to the plane, and used to support the partitions, thereby limiting deformation when the articulated part is bent, said inner abutment having a flexible core (10) extending essentially into said plane of symmetry. Furthermore, the blade comprises means forming outer abutments (11, 12) arranged either side of the wiper lip.

Description

technical field [0001] The invention relates to a wiper for a windshield wiper of an automobile, comprising a hinged part. Background technique [0002] Known wipers for automotive window wipers include: [0003] - a fixed base attached to the arm of the windshield wiper; [0004] - wipe lips; [0005] - a flexible hinged part connecting the lip to the base, the lip extending along the axial mid-plane of the wiper, and the hinged part comprising two curved flexible walls substantially symmetrical to each other with respect to this plane , and a hollowed-out portion is defined between the wall and the base; and [0006] - A stop protruding from the base in the hollowed-out part, symmetrical with respect to said plane, and designed to receive said wall by support and thus limit the bending deformation of the hinged part. [0007] In wipers of this known type, this hinged part may be subject to considerable deformation, especially when the windshield has a complex shape and...
