Pretensioning device for a windscreen wiping device

A windshield wiper device for a vehicle, comprising a wiper blade (2) having

• an elongate upper portion (10) which is constructed so as to be at least partially bendable,
• an elongate lower portion (12) which is constructed so as to be at least partially bendable, and
• a plurality of connection elements (18) connecting the upper portion (10) and the lower portion (12), wherein the connection elements (18) are spaced apart from each other over a longitudinal extent (8) of the windshield wiper device, and wherein the connection elements (18) are configured to enable a movement of the upper portion (10) and the lower portion relative to each other with a movement component over the longitudinal extent (8) of the windshield wiper device, and
• a pretensioning device (50), wherein the pretensioning device (50) comprises a force receiving element (32) which is connected to a force transmission element (33) so that a rotational movement of the force transmission element (33) is brought about in the event of a force action on the force receiving element (32) in a direction of the elongate lower portion (12), whereby a movement of the elongate upper portion (10) results relative to the elongate lower portion (12) with a movement component over the longitudinal extent (8) of the windshield wiper device
• wherein the force transmission element (33) is connected at a first end via a first pivot joint (37) to the elongate upper part (10), and wherein the force transmission element (33) is connected at a second end via a second pivot joint (36) to the force receiving element (32);
• wherein the force transmission element (33) is a first force transmission element, wherein the windshield wiper device includes a second force transmission element (33) connected at a first end via a third pivot joint (37) to the elongate upper part (10), and wherein the second force transmission element (33) is connected at a second end via a fourth pivot joint (36) to the force receiving element (32), wherein the second and fourth pivot joints (36) are disposed at opposite ends of the force receiving element (32).
