Abstract:
1. A fuel efficiency signal device for being interposed between the accelerator pedal of a vehicle and a floor below the pedal, the device signaling to a driver when an accelerator is depressed at a rate equal to or exceeding a selected rate of depression, the signal device comprising: (a) wedge shaped, flexible walled, self supporting air container having walls sealingly connected to adjacent walls to form the air container, the walls, in an installed orientation, comprising, (b) a whistle in one of the walls of the air container having an air passage for escape of air through the passage and thereby generating a sound when the air pressure exceeds a selected air pressure as a result of compression of the signal device by the accelerator pedal at a rate equal to or exceeding a selected rate of depression of the accelerator pedal; and (c) an adjustable air escape valve in a wall of the device for adjustably varying the air flow rate through the air escape valve and thereby adjustably selecting the selected rate of depression.
