Windshield wiper device

A windshield wiper device (100) for a vehicle having a fastening element, the device comprising

• an installation element (50) which is configured for being installed on the fastening element, the installation element (50) including at least one first securing element (51), wherein the at least one first securing element (51) is an elongate slot in a side wall of the installation element (50), wherein the slot includes a first linear section, a second linear section, and a bend therebetween, and
• a wiper blade (2) having
• an elongate upper part (10) which is at least partially of flexible form,
• an elongate lower part (12) which is at least partially of flexible form,
• 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 (2), 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 (2),
• a wiper blade-side fastening part (20), wherein the wiper blade-side fastening part (20) is configured such that, by way of a movement of the wiper blade-side fastening part (20) relative to the installation element (50), a first engagement action can be realized in order to connect the wiper blade-side fastening part (20) to the installation element (50),
• wherein the wiper blade-side fastening part (20) includes at least one first engagement element (21) which is configured to realize the first engagement action with the at least one first securing element (51) of the installation element (50), wherein the at least one first engagement element (21) is a protrusion extending from a side wall of the wiper blade-side fastening part (20) and at least partially into the slot, wherein the entire slot extends in an elongate direction within a plane that is parallel to the longitudinal extent (8) and that is configured to extend perpendicular to a windshield, and wherein the first engagement action includes movement of the protrusion along the slot from the first section to the second section, such that the installation element (50) moves both linearly relatively to the wiper blade (2) along a direction parallel to the longitudinal extent (8), and also rotates relative to the wiper blade (2), and
• a latch mechanism (52, 22) which is configured to fix a position of the wiper blade-side fastening part (20) relative to the installation element (50) after the realization of the first engagement action.
