Abstract: A system to reduce wind noise and turbulent airflow from entering into a sunroof opening of a vehicle, including a sunroof panel slideably connected to the sunroof opening; a rail on a side of the sunroof opening; and a holder fixed in the rail; a deflector assembly including an upper panel pivotally connected to holder and a lower panel connected to the rail. The sunroof panel covers and compresses the deflector assembly in a closed position and covers the sunroof opening, and the deflector assembly rotates and extends when the sunroof panel retracts to an at least a partially open position.

Abstract: A guide block for a sunroof of an automobile including a front channel extending upwards and connecting to a lower channel at a first angle with respect to the lower channel forming a first path, and a rear channel extending upwards and connecting to an upper channel at a second angle with respect to an upper channel forming a second path, where the first path intersects the second path at a cross-over region.
