Abstract

A stow release assembly for a manually translatable steering column assembly includes an upper jacket. The stow release assembly also includes a lower jacket, the upper jacket translatable relative to the lower jacket, the upper jacket translatable between a retracted range and a stowed range. The stow release assembly further includes an electromechanical blocking element coupled to a stationary component of the steering column assembly and moveable between an extended position and a retracted position, the electromechanical blocking element selectively preventing translation of the upper jacket at a plurality of translation positions.

Claims

1. A stow release assembly for a manually translatable steering column assembly comprising:

an upper jacket;

a lower jacket, one of the upper jacket and the lower jacket translatable relative to the other of the lower jacket and the upper jacket over a first telescope range defined by a fully extended position and a first retraction limit, one of the lower jacket and the upper jacket also translatable over a second telescope range defined by the first retraction limit and a second retraction limit; and

an electromechanical blocking element coupled to a stationary component of the steering column assembly and moveable between an extended position and a retracted position, the electromechanical blocking element selectively engageable with a first wall of a component operatively coupled to the upper jacket, to prevent retraction of the upper jacket beyond the first retraction limit when the electromechanical blocking element is in the extended position.

2. The stow release assembly of claim 1, further comprising a second wall, engagement of the electromechanical blocking element with the second wall defining the fully extended position.

3. The stow release assembly of claim 1, further comprising a third wall, the electromechanical blocking element selectively engageable with the third wall to prevent retraction of the upper jacket beyond the second retraction limit when the electromechanical blocking element is in the extended position.

4. The stow release assembly of claim 1, wherein the electromechanical blocking element fixing the upper jacket in at least one position between the first retraction limit and the second retraction limit.

5. The stow release assembly of claim 1, wherein the component operatively coupled to the upper jacket is an energy absorption strap.

6. The stow release assembly of claim 1, wherein the upper jacket is coupleable to a steering input device, the steering device switchable between a rotatable condition and a non-rotational condition in at least one position along the first translation range.

7. The stow release assembly of claim 1, wherein the upper jacket is coupleable to a steering input device, the steering device switchable between a rotatable condition and a non-rotational condition in at least one position along the second translation range.

8. The stow release assembly of claim 1, wherein the electromechanical blocking element is spring biased toward the extended position.

9. A stow release assembly for a manually translatable steering column assembly comprising:

an upper jacket;

a lower jacket, the upper jacket translatable relative to the lower jacket, the upper jacket translatable between a retracted range and a stowed range; and

an electromechanical blocking element coupled to a stationary component of the steering column assembly and moveable between an extended position and a retracted position, the electromechanical blocking element selectively preventing translation of the upper jacket at a plurality of translation positions, wherein the plurality of translation positions comprises a fully extended position, a first retraction limit and a second retraction limit, the fully extended position and the first retraction limit defining a first telescope range, the first retraction limit and the second retraction limit defining a second telescope range.

10. The stow release assembly of claim 9, further comprising an energy absorption strap operatively coupled to the upper jacket, the energy absorption strap having first wall selectively engageable with the electromechanical blocking element to define the first retraction limit.

11. The stow release assembly of claim 9, further comprising a second wall of the energy absorption strap, engagement of the electromechanical blocking element with the second wall defining the fully extended position.

12. The stow release assembly of claim 9, further comprising a third wall of the energy absorption strap, the electromechanical blocking element selectively engageable with the third wall to prevent retraction of the upper jacket beyond the second retraction limit when the electromechanical blocking element is in the extended position.
