Windscreen wiper arm and method for producing the same

摘要

A windscreen wiper arm, particularly for automobiles, has a mounting head mountable on a drive shaft and an arm member pivotally connected to the mounting head by means of a pivot pin, wherein the arm member has a substantially U-shaped cross-section near the pivot pin comprising two side walls, wherein a part of the mounting head extends between the side walls and beyond the pivot pin, wherein the part is provided with opposite abutting surfaces for abutting against the side walls of the arm member; structure is provided on the mounting head and the arm member for limiting a pivot angle of the arm member, in the form of at least one guiding groove on one of the abutting surfaces of the part of the mounting head, as well as at least one outwardly extending finger on the arm member cooperating with the guiding groove. The finger is movable in the guiding groove between a first position corresponding with a wiping position of the arm member and a second position corresponding with a mounting position of the arm member. The finger extends outwardly from a base of the U-shaped cross-section of the arm member in a direction towards the drive shaft.

主权项

1. A windscreen wiper arm, comprising a mounting head mountable adjacent one end thereof on a drive shaft and an arm member pivotally connected to the mounting head adjacent an opposite end thereof by means of a pivot pin, wherein the arm member has a substantially U-shaped cross-section near said pivot pin comprising two side walls, wherein a part of the mounting head extends between the side walls and beyond said pivot pin, wherein said part is provided with opposite abutting surfaces for abutting against the side walls of the arm member, wherein at least one guiding groove is provided on at least one of said abutting surfaces of said part of said mounting head, and including at least one outwardly extending finger on said arm member cooperating with said guiding groove,
wherein said finger is movable in said guiding groove between a first position corresponding with a wiping position of the arm member and a second position corresponding with a mounting position of the arm member, and wherein said at least one finger extends outwardly from a base of the U-shaped cross-section of said arm member in a direction towards said one end of said mounting head and further is integrally formed along an outer side edge thereof with one of said side walls and is laterally spaced along an inner side edge thereof from the other of said side walls of said arm member.
