The invention relates to a wiper lip (20) adapted to a windshield wiper device (20). The windshield wiper device (20) has an elongated, at least partially bendable upper part (10), an elongated, at least partially bendable lower part (12), and a plurality of connection elements (18) for connecting the upper part (10) and the lower part (12). The connection elements (18) are configured to allow a movement of the upper part (10) and of the lower part relative to one another with a movement component along a longitudinal extension (8) of the wiper blade (2). The wiper lip is configured such that the rigidity of the wiper lip in the wiper direction (1) is greater than the rigidity of the wiper lip vertical to the wiping direction.

The invention relates to a drive mechanism and a wiper system for a vehicle. The mechanism comprises a coupling member (22), a drive head (10) having means (20) for connecting to a wiper blade arm (48) and a slide (32) arranged so as to rotatably engage the member with the head when a value of a torque applied to the head relative to the member is less than a predetermined threshold, and, when this is not the case, to rotatably disengage the member and the head by sliding in a direction perpendicular to a rotational axis of the member.

A wiper system wiper system for wiping a window is provided. The wiper system has an arm head and an arm retainer connected to the arm head via a pivot. The wiper system includes a latch for controlling pivoting of the arm retainer with respect to the arm head. The latch is configured to restrict pivoting of the arm retainer with respect to the arm head to an operating range close to the window when the latch is in a latched state. The latch is further configured to allow pivoting of the arm retainer with respect to the arm head from the operating range to a servicing position away from the window when the latch is in an unlatched state.

A windshield wiper system for an aircraft includes a wiper drive shaft with a first end and a second end opposite the first end. The second end includes a first threaded section between the first end and the second end, a second threaded section extending axially along the wiper drive shaft between the first threaded section and the second end relative to a center axis of the wiper drive shaft, and a spline section axially between the first threaded section and the second threaded section. Further included is a first nut to thread to the first threaded section, a second nut to thread to the second threaded section, and a wiper arm assembly including an adjustment sleeve configured to interlock with the spline section, a wiper arm with a first end configured to enclose the adjustment sleeve, and a second end of the wiper arm attached to a wiper blade.

A windshield wiper assembly includes a telescoping wiper head having a first section fixed to a pivot drive shaft and a second section capable of translating relative to the first section between an extended position and a retracted position. A curvilinear guide rail engages the second section and guides the second section between the extended and retracted positions. A wiper blade is carried on the second section. Advantageously the wiper assembly functions to provide enhanced wiper coverage over the Zone B portion of the windscreen through which the occupants view is typically directed.
