Summary:An adjustable steering column assembly includes a column jacket extending along a longitudinal axis. The column jacket includes a compression bracket mounted thereto, and is supported by a mounting bracket. A pawl engages a telescope slot defined by the compression bracket in interlocking engagement to mechanically lock the longitudinal position of the column jacket relative to the mounting bracket. A transverse cam mechanism moves the pawl generally vertically into and out of engagement with the telescope slot. An axial cam mechanism compresses the compression bracket against the mounting bracket. The transverse cam mechanism and the axial cam mechanism are operated by shaft extending along a shaft axis intersecting the column jacket. The transverse cam mechanism and the axial cam mechanism each include first and second cam mechanism disposed on opposing sides of the column jacket and simultaneously operable by a lever.
