The adjustable steering column includes a mounting bracket having a first outer leg, a second outer leg and a cross bar connecting the first and second outer legs. A compression bracket is positioned between the outer legs and includes a first inner leg, a second inner leg and a lower plate connecting the first and second inner legs. The lower plate includes a spring slot. A column jacket is secured to the compression bracket and extends along a first axis. A rake bolt extends through the mounting bracket and compression bracket. A coil spring is seated on the cross bar and is secured to the rake bolt. The coil spring extends through the spring slot in the lower plate and supports the column jacket with the steering column in an unlocked condition. ## Claims ### Claim 1 An adjustable steering column for a vehicle, the adjustable steering column comprising: a mounting bracket configured to be secured to an adjacent vehicle component, the mounting bracket comprising a first outer leg, a second outer leg, and a cross bar connecting the first outer leg to the second outer leg, the first outer leg and second outer leg each include a rake slot; a compression bracket comprising a first inner leg, a second inner leg, and a lower plate connecting the first inner leg to the second inner leg, the first inner leg and second inner leg each including a telescope slot and the lower plate comprising a spring slot; a column jacket secured to the compression bracket and extending along a first axis, the column jacket comprising a lower jacket and an upper jacket telescopically coupled to the lower jacket; a rake bolt extending through the mounting bracket and compression bracket, and movable in a rake direction; and a coil spring seated on the cross bar of the mounting bracket and secured to the rake bolt, the coil spring extending through the spring slot in the lower plate of the compression bracket. ### Claim 2 (depends on 1) The adjustable steering column of claim 1, further comprising a seat plate fixed to the rake bolt, and the coil spring is seated against the seat plate to support the column jacket in a rake direction via the rake bolt when the adjustable steering column is in an unlocked condition. ### Claim 3 (depends on 2) The adjustable steering column of claim 2, wherein the compression bracket is movable relative to the coil spring such that the spring slot in the lower plate moves relative to the coil spring. ### Claim 4 (depends on 1) The adjustable steering column of claim 1, wherein the coil spring is seated at a seat on the cross bar of the mounting bracket, and the seat includes a post configured to extend within the coil spring. ### Claim 5 (depends on 1) The adjustable steering column of claim 1, further comprising a locking mechanism configured to selectively apply a clamping force to place the steering column in a locked condition and selectively release the clamping force to place the steering column in an unlocked condition. ### Claim 6 (depends on 5) The adjustable steering column of claim 5, wherein the clamping force causes the mounting bracket to support the compression bracket and column jacket in the rake direction when the steering column is in the locked condition. ### Claim 7 (depends on 5) The adjustable able steering column of claim 5, wherein the coil spring supports the column jacket via the compression bracket when the steering column is in the unlocked condition. ### Claim 8 (depends on 7) The adjustable steering column of claim 7, wherein the rake bolt and compression bracket are movable relative to the mounting bracket in the rake direction with the steering column in the unlocked condition. ### Claim 9 (depends on 8) The adjustable steering column of claim 8, wherein the compression bracket is movable relative to the rake bolt and coil spring in the telescope direction with the steering column in the unlocked condition.
