Patent ID: 8850918

Claim:
An adjustable steering column comprising a position lock for resisting raking and telescoping movement of the steering column; the position lock comprising a gear positioned and configured to cause a shaft to rotate about its central axis as the steering column telescopes; the position lock further comprising one or more telescoping friction plates arranged and configured so as to rotate with the shaft when the steering column telescopes; the position lock further comprising one or more raking friction plates, each raking friction plate being positioned in frictional contact with at least one of the one or more telescoping friction plates and configured to exhibit a different rotation than the one or more telescoping friction plates when the steering column telescopes; the shaft imposing a compressive load between the one or more telescoping friction plates and the one or more raking friction plates so as to induce friction between the one or more telescoping friction plates and the one or more raking friction plates and thereby resist their relative movement.
