Multi-position roller blind for vehicle, and corresponding vehicle

The blind has an occultation canvas driven by a drawing bar (3) comprising an end carrying blocking units (4). The bar is immobilized when the units (4) are in stop position, and the bar is moved along guiding rails (1, 2) when the units (4) are in movement position. The bar supports a handle (31) acting on the units (4) through a flexible rod (41) for controlling the passage from stop to movement positions and vice-versa. An independent claim is also included for a motor vehicle comprising a roller blind.
