Embodiment Construction

[0022] The fastening part 10 for the windshield wiper has at its one end a receiving opening 12 or 46 ( FIG. 10 ) for receiving the wiper shaft 44 and at its other end forms a component 14 of the folding hinge ( FIG. 1 ). Furthermore, the fastening part 10 has at this end a shaped spring suspension 16 on which a C-shaped hook 18 of a tension spring (not shown) engages. The spring suspension 16 is formed by deep drawing from the side walls 24 of the U-shaped cross-sectional profile 20 ( FIGS. 2 and 9 ).

[0023] Via the C-shaped hook 18, considerable tensile forces 64 and 66 act on the spring suspension 16 from different directions. The cross-section of the spring suspension 16 has a circular hollow profile, which has a maximum cross-section in the transition region to the side wall 24 until it is reduced to a constriction 34, whereby the cross-section of the spring suspension 16 The section is correspondingly solidly constructed. The constriction 34 forms the engagement regi...

Abstract

The invention relates to a mounting (10) for a windshield wiper, the mounting having at one end a receiving hole (12, 46) for a wiper shaft (44), forming a fold at the other end A component (14) of the hinge, and formed by deep drawing, stamping and bending from a flat plate (28), has a U-shaped cross-sectional profile (20) and a spring suspension (16). It is proposed that the spring suspension (16) is formed from a side wall (24) of the U-shaped cross-sectional profile (20) by deep drawing.

Description

technical field [0001] The invention relates to a mounting for a windshield wiper. Background technique [0002] The known windshield wiper has a wiper arm consisting of a driven fastening part and an articulation part with a wiper lever connected to it by a folding hinge. A wiper blade is hinged to the free end of the wiper rod. During the swivel movement of the windshield wiper blade, the wiper blade moves over the vehicle windshield, a tension spring tensioning the folding hinge so that the wiper blade is pulled towards the windshield. [0003] The tension spring is housed in the U-shaped cross-sectional profile of the hinge and is suspended at one end from a transverse pin of the hinge. The other end of the tension spring is fixed on the spring suspension device on the fixture by a C-shaped hook. In known fastening elements, the spring suspension is either formed on or consists of a rivet. For example, in a variant, the fixing part, which is formed as a plate bend, h...
