An open roof construction for a vehicle comprises a panel for a roof opening and a wind deflector assembly positioned at the front edge of the roof opening. The wind deflector assembly is provided with a substantially rigid upper frame member extending at least along the front edge. A flexible member connects with an upper edge to said upper frame member and with a lower edge to a stationary part. The upper frame member is movable by an operating mechanism between a lower, inactive position and at least two upper, active positions. Tensioning members keep the flexible member taut over in all active positions, and is provided with a substantially rigid, elongate lower frame member at its lower edge. The lower frame member connects to the stationary part through the tensioning members having a maximum tension force which is substantially lower than a maximum operating force of the operating mechanism.
