A pantographic wiper arm assembly (102) comprising a main arm (104) having a spindle bracket (108) for attaching the main arm to a spindle of a drive unit for reciprocating the main arm about a main axis. A wiper attachment (120) is spaced along the main arm from the spindle bracket for attaching a wiper blade to the main arm, wherein the wiper attachment is secured to the main arm to rotate about a wiper axis. An auxiliary arm (106) is rotatably connected at one end to the wiper attachment to rotate relative to the wiper attachment about a first auxiliary axis off-set from the wiper axis. An auxiliary bracket (112) for coupling the auxiliary arm at its other end to the drive unit to rotate relative to the auxiliary bracket about a second auxiliary axis having a fixed offset from the main axis, thereby rotating the wiper attachment about the wiper axis in a pantographic motion as the main arm rotates about the main axis, wherein the auxiliary arm is disposed along the main arm in an at least partially overlapping relationship.
