Sun visor arrangement for side window of vehicle, has bias unit pre-tensioning locking unit to block guide bar with respect to movement relative to tubular covering, where sun visor substrate is positioned in stressed position

摘要

The arrangement has a positioning mechanism (4) comprising a locking unit (42) and a bias unit (43) for pre-tensioning the locking unit. A guide bar (32) is moved upwardly when a sun visor substrate (23) is moved from a rolled-up position into a stressed position. A draw bar (24) is driven until a low end of the guide bar reaches an upper section of a tubular covering (31). The bias unit pre-tensions the locking unit to block the guide bar with respect to movement relative to the tubular covering, where the sun visor substrate is positioned in the stressed position.
