Windscreen wiper apparatus

A windscreen wiper apparatus comprising

• at least one wiper blade (14),
• at least one heating element (16, 16′) that is arranged on the wiper blade (14),
• at least one wiper blade adapter (18),
• at least one wiper arm adapter (50) configured to be connected along a longitudinal axis (24) of the wiper blade adapter (18) to the wiper blade adapter (18),
• at least one electrical connecting unit (38) that is arranged at least in part on the wiper arm adapter (50) and in part on the wiper blade adapter (18) and that is configured to be connected to or disconnected from the at least one heating element (16, 16′) by a translatory movement of the wiper blade adapter (18) relative to the wiper arm adapter (50) along or parallel to the longitudinal axis (24) of the wiper blade adapter (18), wherein the at least one wiper blade adapter (18) has at least one electrical interface element (28) that forms an electrical connecting element of the at least one electrical connecting unit (38) and that is connected to the wiper blade (14) in such a manner that said electrical interface element is unable to move with respect to the at least one heating element (16, 16′);
• and
• at least one fluid-carrying interface element (64) so as to provide a coupling to a further fluid-carrying interface element (66) arranged on the at least one wiper arm adapter (50);
• wherein the at least one wiper blade adapter (18) comprises at least one adapter base body (54) and at least one covering element (60) that is connected to the adapter base body (54) in such a manner that said covering element is unable to move and the at least one electrical connecting element of the electrical connecting unit (38) is arranged on said covering element, wherein the at least one covering element (60) guides at least one electrical line (30) so as to supply the at least one heating element (16, 16′) with electrical energy, wherein the at least one covering element (60) is a separate element from the at least one fluid-carrying interface element (64), and wherein the at least one covering element (60) does not guide or delimit a fluid-carrying line element.
