Lever gear for a wheel wind deflector and method for operating a lever gear with overload protection

A lever system for a movable wheel wind deflector which is fitted to a vehicle, the lever system comprising:

• a first lever and
• a second lever pivotably connected to the first lever at a rotatable connection,
• wherein the rotatable connection includes:
• a sleeve defining a cavity;
• a spring disposed within the cavity of the sleeve:
• a ball disposed at least partially within the sleeve and biased in a direction out of the sleeve cavity by the spring;
• wherein in a non-overload state the ball is disposed within a recess and held in the recess by the spring, and the rotatable connection defines a first pivot axis between the first and second levers, wherein the first pivot axis extends through the ball and the recess;
• wherein in an overload state, in response to resistance on the movable component, the ball is disposed outside of the recess and biased into an outer counter, and the rotatable connection defines a second pivot axis between the first and second levers that is different than the first pivot axis, wherein the second pivot axis extends through the ball and the outer contour;
• wherein the ball is guided along the outer contour, and the second pivot axis between the first and the second levers corresponds to the location of the ball within the outer contour.
