In a vehicle wiper device, a retaining portion is formed inside an arm piece at respective areas of a base end side fixing section, a main body, and a leading end side fixing section of the arm piece. A hose is retained by the retaining portion. This thereby enables the hose to be retained to the arm piece without using a retaining member, such as a holder, to retain the hose to the arm piece. Moreover, disposing the hose inside the arm piece enables the hose to be suppressed from being exposed or projecting out from the arm piece. The hose can accordingly be retained in the arm piece without having a detrimental effect on the appearance and while suppressing an increase in cost of the vehicle wiper device.

The invention relates to a cleaning arrangement (40; 40a-40d) for cleaning a vehicle window, with a wiper arm (10; 10a-10d) and with at least one hose (31, 32), fastened to the wiper arm (10; 10a-10d), for a cleaning fluid. It is provided according to the invention that the hose (31, 32) is connected by a form-fitting fastening, secure with regard to rotation angle, at least indirectly to the wiper arm (10; 10a-10d).

The invention relates to a wiper arm (10; 10a-10d) for cleaning a vehicle window, with a carrier element (11), which is able to be connected at a first end region at least indirectly with a drive shaft and at another end region with a wiper blade (1), and with an additional element (30) connected with the carrier element (11), which additional element (30) extends in longitudinal direction of the wiper arm. It is provided according to the invention that the additional element (30) has at least one air guide section (166, 167), extending in longitudinal direction of the wiper arm (10; 10a-10d), which at least one air guide section (166, 167) projects beyond the underside (168) of the carrier element (11) on the side facing the vehicle window.

The invention relates to a wiper arm head (14) for a wiper arm rod (11), with a first end region (178), which has an opening (15) for receiving a drive shaft, and a second end region (179) for the pivotable fastening of the wiper arm rod (11), and with means for directing at least one hose (31, 32) carrying a cleaning fluid. It is provided according to the invention that the means has a feedthrough (181, 182), which leads the hose (31, 32) from an upper side (187) in the direction of an underside (188) of the wiper arm head (14).

The present application relates to a wiper arm, which comprises a wiper arm body and a wiper arm end piece, the wiper arm end piece being fixedly connected to one end of the wiper arm body to hold a wiper blade, the wiper arm being further provided with a nozzle and a hose, wherein the nozzle is connected to an extension section of the wiper arm end piece towards the return side or the outward swing side of the wiper arm; the hose extends along the wiper arm body, and one end of the hose is connected to the nozzle to deliver a cleaning fluid to the nozzle. The arrangement of a nozzle on the wiper arm ensures that a cleaning fluid is quickly wiped off, the driver is given a clear field of vision, and the cleaning fluid usage may also be reduced.

A windscreen wiper arm (1), comprising a mounting head (2) mountable on a drive shaft (3) and a first arm member (4) at one end thereof being pivotally connected to the mounting head (2) by means of a pivot pin (8) and at another end thereof being rigidly connected to a second arm member (5) arranged to be connected to an elongated wiper blade (6) to be placed in abutment with the windscreen to be wiped. The first (4) and said second (5) arm members can oscillate to-and-from between a first reversal position and a second reversal position. The second arm member (5) is made in one piece and has a substantially U-shaped cross-section defining a housing between a base and legs of said U-shaped cross-section. The housing is arranged to accommodate at least one channel (14, 15) for a washing liquid and/or electricity wiring.

A wiper arm device (10a; 10b) having at least one wiper arm adapter (12a; 12b), having at least one fluidic coupling element (18a; 18b) for forming a fluidic connection with at least one wiper blade (62a; 62b), having at least one wiper arm rod (14a; 14b), having at least one fluid line (16a, 16a; 16b, 16b) for transporting wiper fluid along the wiper arm rod (14a; 14b) to the fluidic coupling element (18a; 18b), and having an electrical heating line (20a, 20a; 20b) which is arranged in the fluid line (16a, 16a; 16b, 16b) for heating the fluid line (16a, 16a; 16b, 16b). The heating line (20a, 20a; 20b) extends through the at least one fluid line (16a, 16a; 16b, 16b) and is deflected at the fluidic coupling element (18a; 18b) to form a return through the fluid line (16a, 16a; 16b, 16b).

The invention relates to a cleaning arrangement (10; 10a) for a wiper arm (1) of a windscreen wiper system (100), wherein the cleaning arrangement (10; 10e) has at least one spray nozzle (21, 22) for a cleaning fluid, wherein the cleaning arrangement (10; 10a) is constructed to form en engagement connection (30) at the wiper arm (1), and wherein the engagement connection (30) comprises at the cleaning arrangement (10; 10a) at least one resiliently constructed engagement element (40; 40a) which is constructed to cooperate with an engagement mount (54; 54a) at the wiper arm (1). There is provision according to the invention for the cleaning arrangement (10; 10a) to have first guide means (35), which first guide means (35) are constructed to be able to rotate the cleaning arrangement (10; 10a) in a rotation axis (37) in order to establish the engagement connection (30).

A wind deflector for a windscreen wiper system of a motor vehicle has a receptacle for fastening the wind deflector to a component of a wiper arm of the windscreen wiper system. The wind deflector has at least two parts which can be mounted in a divided state on the component of the wiper arm and subsequently can be joined together, as a result of which the wind deflector can be secured to the component of the wiper arm of the windscreen wiper system.
