Windscreen wiper arm

A method for manufacturing a windscreen wiper arm, comprising the steps of:

• preparing a mounting head mountable on a drive shaft;
• and
• pivotally connecting an arm member to the mounting head 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 of the arm member and beyond said pivot pin,
• wherein the mounting head has at least one groove for limiting a pivot angle of the arm member,
• wherein the at least one groove of the mounting head has groove side walls,
• wherein the arm member has at least one protrusion which cooperates with said groove,
• wherein said at least one protrusion is movable in said at least one groove along a path 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,
• wherein said part is provided with opposite abutting surfaces for abutting against the side walls of the arm member and wherein said at least one groove is provided on one of said abutting surfaces,
• wherein said at least one protrusion extends laterally inwardly from one of the side walls of said arm member into said groove, wherein
• wherein said groove side walls are spaced apart from one another in a direction that is transverse to the path by a width which is larger than a width of said protrusion such that said protrusion is movable along the path in said groove for the entire length between said first and second positions without making contact with the groove side walls of said groove.
