METHOD OF INTERLOCKING SELF-PROPELLED VEHICLE STEERING MECHANISM Russian patent published in 2010 - IPC B60R25/02 

FIELD: transport.

SUBSTANCE: invention relates to mechanical vehicle antitheft devices. Proposed antitheft method comprises inhibiting access to steering wheel by fitting mechanical anti-seal device onto said steering wheel. Device represents 3D round reinforced housing accommodating steering wheel with hole on the side of steering column that revolves rotation to the right and left. Specific properties of collet mechanism are used to implement proposed method. Said mechanism can embrace round parts and is incorporated with the device one-piece housing made from high-strength materials. Said collet mechanism is used to impart rectilinear motion to arc-like plates with bent edges in radial directions. Arc-like plates make device housing circular edges to completely enclose steering wheel rim. To install or withdraw aforesaid device, arc-like plates are first moved radially apart with the help of built-in drive elements that increase designed housing diametre and hole sizes. To actuate the proposed device, said arc-like plates are displaced towards the housing center to completely cover steering wheel rim.

EFFECT: higher reliability of antitheft device.
