<p>An apparatus to provide additional locking effort, in the event of vehicle crash, of a clamping mechanism of an adjustable steering column (1) for a vehicle, the apparatus having a lock device including a cam (22, 23) actuable on a first tapering lock part (15), there being a second lock body part (14) provided with a reaction surface (16) against which a taper (17) of the first part can react in the event of vehicle crash. A third part (12) engages with the first part in order to hold the first, second and third parts in locking relationship in the event of vehicle crash. When the mechanism is in its clamped condition, the cam acts on the first part to hold it against the third part and, upon crash, the first and second parts interreact by means of their tapering surfaces to firmly wedge these components together.</p> |
