| Abstract: |
An air flow control device for an automotive vehicle includes an air flow control fin pivotably secured near the rear end of a vehicle. The air flow control fin is pivotable to either of two angular positions with respect to the vehicle body. A manual operator is disposed within a vehicle compartment and is connected to the air flow control fin through a remote control mechanism. The air flow control fin is movable between a first spoiler position in which the fin diverts air flowing along vehicle body surface upwards so as to exert a downward force and enhance the traction of the vehicular wheels, and a second air flow guide position in which the fin guides the air flow toward a rear window surface so as to remove rain water, dust and so forth. The manual operator can be operated by a driver in the vehicle compartment to select either the first spoiler position or the second air flow guide position.

What is claimed is:
1. An air flow control fin for a vehicle having a rear window, comprising:
- a fin having a first section and a second section connected to said first section in oblique fashion, said first section having a first surface and said second section having a second surface said fin being mounted on a roof of the vehicle adjacent said rear window and pivotable between a first position in which said first surface splits air flowing along the roof, and a second position in which said second surface directs said air flowing along the roof to flow along said rear windows; and
- mounting means secured to said fin adjacent said oblique connection for pivotally mounting said fin on said roof adjacent said rear window, said mounting means allowing pivotable movement of said fin between said first position and said second position, said mounting means including means for holding said fin in a selected one of said first and second positions, said holding means including a lever pivotable about a pivot axis and having a projection engaged with a slot in a member operatively engaging said fin, said lever being arranged to receive a force exerted on said fin and to alter the direction of said force toward said pivot axis to establish a holding force for holding said fin at said selection position;
- wherein said first position directs said first surface toward said air flowing along said roof and directs the air upward, and wherein said second position directs said second surface to said air flow and guides said air flow towards said rear window.
