Patent ID: 7618080

Claim:
A vehicle comprising: a roof having roof parts movably connected together such that the roof parts are movable between a closed position of the roof in which the roof parts cover the vehicle interior and a stored position of the roof in which the roof parts expose the vehicle interior; a roof part kinematic system having a front guide rod pivotably supported at one end about a first vehicle body-side rotary joint and pivotably supported at another end to a first one of the roof parts to movably connect first roof part to the vehicle body such that upon actuation of the roof part kinematic system the roof part kinematic system moves the roof parts between the closed and stored positions; and a transmission kinematic system having a spring connected at one end to the front guide rod, wherein the spring acts on the front guide rod with a swivel torque about the first rotary joint during the transfer of the roof parts between the closed and stored positions, wherein an orientation of the spring traverses the first rotary joint during the transfer of the roof parts between the closed and stored positions; wherein the spring has a displaceable base facing away from the front guide rod, wherein the position of the spring base is a function of the position of the first roof part during the transfer of the roof parts between the closed and stored positions.
