Windshield wiper device having improved creep behavior

A method for reducing material creep processes of a windshield wiper device, comprising:

• providing (201) a windshield wiper device for a vehicle, comprising a wiper blade (2) with an elongate upper part (10) which is configured to be at least partially flexible, an elongate lower part (12) which is configured to be at least partially flexible, and multiple connecting elements (18) connecting the upper part (10) and the lower part (12), wherein the connecting elements (18) are spaced apart from one another along a longitudinal extent (8) of the wiper blade, and wherein the connecting elements (18) are configured to permit a movement of the upper part (10) and of the lower part relative to one another with a movement component along the longitudinal extent (8) of the wiper blade,
• loading (202) the windshield wiper device before final installation of the windshield wiper device on a vehicle, such that, after final installation of the windshield wiper device, a primary creep behavior of the windshield wiper device is substantially reduced, wherein the loading (202) of the windshield wiper device comprises the windshield wiper device being placed into a mold (50), wherein the mold is configured to preload the windshield wiper device to reduce the primary creep behavior of the windshield wiper device during at least one of shipping or storage of the windshield wiper device in the mold, and wherein the mold is a windshield wiper shipping container sized and shaped for the windshield wiper device.
