Abstract
Abstract An adjustable steering assembly for vehicles pivotable forwardly and rearwardly about upper and lower pivots, the upper pivot being operably connected to the steering column by a swingable link which is adapted to actuate along said steering column an axially slidable adjustment sleeve assembly. The sleeve assembly includes a manually adjustable spring actuator for adjusting axially of the steering column the position of a detent device which in turn allows angular adjustment of the steering column for the comfort of operators of different sizes and heights and to provide a fully forward tilted position at which improved access to vehicle components is provided.
