Patent ID: 6836926

Claim:
A wiper blade for windows, comprising: at least one support element ( 12 ), a wiper strip ( 14 ), and a connecting device ( 16 ) for a wiper arm ( 18 ), wherein the support element ( 12 ) is an elongated, flat bar to which the wiper strip ( 14 ) and the connecting device ( 16 ) are attached, wherein the support element ( 12 ) has a cross sectional profile in which F wf * L 2 48 * E * I zz < 0.009 , where F wf is an actual contact force exerted on the wiper blade by the wiper arm ( 18 ) in condition when it is pressed against a window, L is a length of the support element ( 12 ), E is an elasticity modulus of the support element ( 12 ), and I zz is a moment of inertia of a cross sectional profile around a z-axis perpendicular to an taxis, which adapts along with the support element ( 12 ), and perpendicular to a y-axis, wherein the support element ( 12 ) has a substantially rectangular cross sectional profile ( 40 ), with a substantially constant width b and a substantially constant thickness d.
