<p>An anti-theft security arrangement for the steering column (1) of a motor vehicle includes a clutch (9,10) which is adapted to resist turning of the steering up to a certain torque but thereafter to slip to avoid damage to the parts while still making control of the vehicle impractical. The clutch is arranged on a parallel axis to the steering column (1) and is connected to the column through a high-ratio gear train comprising a gear wheel (4) fast with the steering column and a pinion (8) fast with the clutch. It is engaged and disengaged by sliding the assembly of clutch (9,10) and pinion (8) into and out of mesh with the other gear wheel (4). The clutch includes a rotatable shaft (6) with teeth (9) engaging between spring steel rods (10) so as to turn in a series of discrete jerks if the limiting torque is exceeded. <IMAGE> <IMAGE></p> |
