Vehicle windscreen wiper device has structure that forces second coupler to first angular region by mechanical engagement when second coupler is outside first angular region

摘要

The device is mounted between the window (8) and a support (4) for the window with an opening opened and closed by the window. The device has a drive (1) carried by the support with a driven shaft (5), a first coupler (22) pivoted in a first angular range, a pivoting shaft (9) rotatably supported by the window and with its axis aligned with that of the driven shaft with the window closed, a second coupler (10) attached to the pivoting shaft for transferring the driven shaft rotation to the pivoting shaft when in a suitable position with the window closed and a wiper arm. A guide structure guides the second coupler to the first angular region by mechanical engagement when the second coupler is outside the first angular region.
