Locking mechanism and open roof construction provided there-with

A locking mechanism for a movable member of an open roof construction for a vehicle, comprising a stationary part which is provided with a first guide, a locking lever movable in a first direction configured to drive said movable member and for locking said movable member in a predetermined position and an operating part movable in said first direction configured to control the movement of the locking lever, wherein the locking lever comprises a first cam cooperating with the first guide, which first guide comprises a first guide part extending in a direction substantially in parallel to said first direction and a second guide part connecting to said first guide part and extending in a second direction different from the first direction and capable of receiving the first cam of the locking lever for preventing a further movement of the locking lever in said first direction, wherein the locking lever and the operating part comprise an assembly of a second cam and a second curved guide, wherein a cooperation between the second cam and the second curved guide is capable of generating a force on the locking lever in a first/second sense along the second direction when the operating part is moved in a first/second sense along said first direction, such that the first cam of the locking lever moves into/out of the second guide part of the first guide in said second direction while the second cam moves out of/into the second curved guide, such that, when the first cam is positioned in the first guide part, the locking lever moves in the first direction together with the operating part whereas, when the first cam is positioned in the second guide part and the locking lever is prevented from moving in the first direction, the operating part is capable of moving further in said first direction without the locking lever, and wherein further retaining means are provided which are capable of retaining the locking lever in the position in which the first cam is positioned in the second guide part of the first guide, wherein said retaining means comprise a retaining member which substantially in said first direction is movable relative to the locking lever between a retaining position, when the first cam is positioned in the second guide part, for preventing a movement of the first cam of the locking lever in the second sense along the second direction out of the second guide part, and a release position for allowing such a movement of the first cam, wherein the movement of the retaining member between the retaining and release positions and vice versa in the first direction is a result of a movement of the operating part in said first direction, and wherein the operating part, in the release position, engages the retaining member in such a manner that the retaining member in said release position is incapable of generating a force on the locking lever in said second direction that would prevent a movement of the first cam in the second direction.
