Abstract

There is provided an aerodynamic stabilizer assembly adapted to be mounted in the rear portion of the roof of a motor vehicle. The assembly includes a framework having a front edge and partitioned to define separate openings. A pair of elongated air deflection panels each sized to cover one of the framework openings and each air deflection panel being pivotedly mounted to the framework along a longitudinal axis at the front edge of the assembly framework and being pivotable between a lowered passive position and a raised active position. There are springs arranged on each longitudinal axis for biasing each air deflection panel in the passive position. The assembly framework also includes cables means for limiting the upward rotational movement of the rear edge of each of the panels beyond the raised active position. When a motor vehicle is moving at a high rate of speed and is spinning out the low pressure of the air moving across the roof creates a pressure differential which acts on the panels and causes the panels to rotate to the active raised position thereby resulting in a downward force urging the motor vehicle against the road.
