ABSTRACT:
A rigid security bar is telescopically mounted in a tubular spoke of a steering wheel for movement between retracted and extended positions concealed within the spoke and protruding radially beyond the wheel rim to prevent effective wheel movement by obstruction with a vehicle windshield. A locking mechanism secures the security bar in either position and a biassing spring is mounted in the spoke in engagement with an inner end of the security bar pushing the security bar to be extended for a short distance exposing an end for pulling out by the driver to the fully extended position. A plurality of tubular spokes with associated security bars can extend chordal fashion between opposite sides of the rim. An anchoring chain can be attached to an inner end of the security bar extending around an air bag housing mounted centrally of the wheel.
