An open roof system for a vehicle having an opening in its fixed roof, comprising: a stationary part configured to be fixed to the roof, at least first and second movable elements (41,51), which are each movable between a retracted position and a deployed position, a motor configured to drive the movable elements (41,51) at least partly between the retracted and deployed positions, at least first and second drive cable assemblies (7,8) configured to transfer torque of the motor to said movable elements (41,51), wherein the stationary part comprises at least first and second guiding channels (9,9',10,10',17,17') and guides for respectively guiding the drive cable assemblies (7,8) and the movable elements (41,51), whereby the first and second drive cable assemblies (7,8) comprise a flexible first part (13,14) having first and second end portions (13',13"14',14"), said flexible first part (13,14) being driven by the motor, such that said first end portion (13',14') of said flexible first part (13,14) is on one side of the motor and the second end portion (13",14") is on the other side of the motor and said second end portion (13",14") is guided in a first guiding channel (9,9',10,10'), wherein at least one of the first and second drive cable assemblies (7,8) further comprises at least one elongated second part (15,16), guided in a second guiding channel (17,17'), wherein at least a part of the second guiding channel (17,17') extends side-by-side to the first guiding channel (9,9',10,10'), and wherein, during at least part of the operation, said elongated second part (15,16) is driven by and is moved substantially in the same direction as the second end portion (13",14") of the first part (13,14) of the cable assembly (7,8) at a position where the first and second guiding channels (9,9',10,10',17,17') extend side-by-side, and wherein said first flexible parts (13,14) and the second elongated parts (15,16) of the first and second drive cable assemblies (7,8) together drive said at least first and second movable elements (41,51), characterized in that the first and second movable elements (41,51) are positioned side-by-side in relation to their direction of movement and in that the second elongated parts (15,16) of the first and second drive cable assemblies (7,8), which are also flexible parts, are guided through the second guiding channels (17,17') which extend through a curved path, wherein the first and second guiding channels (9,9',10,10',17,17') of at least one of the drive cable assemblies (7, 8) extend side-by-side in a transverse portion of the stationary part. a stationary part configured to be fixed to the roof, at least first and second movable elements (41,51), which are each movable between a retracted position and a deployed position, a motor configured to drive the movable elements (41,51) at least partly between the retracted and deployed positions, at least first and second drive cable assemblies (7,8) configured to transfer torque of the motor to said movable elements (41,51), wherein the stationary part comprises at least first and second guiding channels (9,9',10,10',17,17') and guides for respectively guiding the drive cable assemblies (7,8) and the movable elements (41,51), whereby the first and second drive cable assemblies (7,8) comprise a flexible first part (13,14) having first and second end portions (13',13"14',14"), said flexible first part (13,14) being driven by the motor, such that said first end portion (13',14') of said flexible first part (13,14) is on one side of the motor and the second end portion (13",14") is on the other side of the motor and said second end portion (13",14") is guided in a first guiding channel (9,9',10,10'), wherein at least one of the first and second drive cable assemblies (7,8) further comprises at least one elongated second part (15,16), guided in a second guiding channel (17,17'), wherein at least a part of the second guiding channel (17,17') extends side-by-side to the first guiding channel (9,9',10,10'), and wherein, during at least part of the operation, said elongated second part (15,16) is driven by and is moved substantially in the same direction as the second end portion (13",14") of the first part (13,14) of the cable assembly (7,8) at a position where the first and second guiding channels (9,9',10,10',17,17') extend side-by-side, and wherein said first flexible parts (13,14) and the second elongated parts (15,16) of the first and second drive cable assemblies (7,8) together drive said at least first and second movable elements (41,51), characterized in that the first and second movable elements (41,51) are positioned side-by-side in relation to their direction of movement and in that the second elongated parts (15,16) of the first and second drive cable assemblies (7,8), which are also flexible parts, are guided through the second guiding channels (17,17') which extend through a curved path, wherein the first and second guiding channels (9,9',10,10',17,17') of at least one of the drive cable assemblies (7, 8) extend side-by-side in a transverse portion of the stationary part.
