-
FIGS. 1 and 2 illustrate a steering column assembly generally indicated with numeral 10. The steering column assembly 10 is for a vehicle and extends along a longitudinal axis X. The steering column assembly 10 may be adjustable in a telescopic direction generally parallel with the longitudinal axis X (i.e., adjustable along the longitudinal axis X), and may be adjustable in a rake/tilt direction in some embodiments. The steering column assembly 10 includes alower jacket 12, anupper jacket 13, and asteering shaft 14 extending along the longitudinal axis X. Thesteering shaft 14 and theupper jacket 13 are operatively coupled to each other and disposed in telescoping engagement with thelower jacket 12. In other words, thesteering shaft 14 has a portion disposed within theupper jacket 13 and a portion disposed within thelower jacket 12. Theupper jacket 13 has a portion extending into thelower jacket 12 and is translatable therein. - A
telescope actuator assembly 30 is provided to facilitate powered telescope adjustments of theupper jacket 13 and thesteering shaft 14. Thetelescope actuator assembly 30 includes aleadscrew 32 having anut 34 threaded thereto. Amotor 36 drives theleadscrew 32 to translate thenut 34 therealong. Thenut 34 is operatively coupled to theupper jacket 13 with adrive bracket 38, such that linear movement of thenut 34 along theleadscrew 32 drives theupper jacket 13 to and from different telescope positions. - Referring now to
FIG. 3 , thedrive bracket 38 connection to theupper jacket 13 is shown in greater detail. In particular, thedrive bracket 38 includes a base portion 40 that extends longitudinally in a direction substantially parallel to the longitudinal axis X. While it is contemplated that the base portion 40 of thedrive bracket 38 may be directly secured to an outer surface of theupper jacket 13, aplate 42 is provided in some embodiments, as illustrated. Theplate 42 may be welded to theupper jacket 13 in some embodiments, but other securing processes are contemplated. Theplate 42 provides additional material thickness to better facilitate mechanical fastening of thedrive bracket 38—and/or possible other components—to theupper jacket 13. The base portion 40 of thedrive bracket 38 may be fastened to theplate 42 andupper jacket 13 with bolts, rivets or the like. - As shown in
FIGS. 1-3 , theplate 42 and the base portion 40 extend through a slot 44 defined by abridge 46 of thelower jacket 12. Specifically, the slot 44 is defined by an outer wall 48 and a pair ofsidewalls 49. As theupper jacket 13 and thesteering shaft 14 translate during powered telescopic adjustment, theplate 42 and the base portion 40 slide through the slot 44. - Referring now to
FIGS. 4-6 , a retention feature that resists rearward translation of theupper jacket 13 andsteering shaft 14 beyond a predetermined position is illustrated according to one aspect of the disclosure. The retention feature includes a pair ofsteps 50 formed on theplate 42. The pair ofsteps 50 extend laterally to an extent necessary to not be able to pass through the slot 44 defined by thebridge 46. In other words, theplate 42 includes a first portion 52 having a first width and asecond portion 54 having a second width that is greater than the first width. The pair ofsteps 50 contact aforward face 56 of thebridge 46 to define the rearward movement limit. - In the illustrated embodiment, a pair of steps are provided, but it is contemplated that only one side of the
plate 42 has astep 50. Additionally, it is contemplated that the base portion 40 of thedrive bracket 38 includes thesteps 50, rather than theplate 42, or in addition to theplate 42. - Referring now to
FIG. 7 , another aspect of the retention feature is shown. The retention feature in the illustrated embodiment is atapered region 60 of theplate 42. In particular, theplate 42 tapers inwardly from a greater width to a narrower width in a direction from forward to rearward of theplate 42 andupper jacket 13. The tapering is dimensioned to ensure a frictional slowing and eventual stopping of the rearward movement of theplate 42 during translation. This is accomplished by frictional engagement between theplate 42 and thesidewalls 49 and/or forward face 56 of thebridge 46. It is contemplated that the base portion 40 of thedrive bracket 38 includes the tapered profile, rather than theplate 42, or in addition to theplate 42. - Referring now to
FIG. 8 , another aspect of the retention feature is shown. The retention feature in the illustrated embodiment is simply an enlarged end of theplate 42 that does not permit any portion of theplate 42 to extend to a rearward side of thebridge 46. In other words, unlike the embodiments ofFIGS. 1-7 , theplate 42 does not pass through a slot of thebridge 46 and the end of theplate 42 simply contacts theforward face 56 of thebridge 46 at the rearward travel limit. - While the invention has been described in detail in connection with only a limited number of embodiments, it is to be readily understood that the invention is not limited to such disclosed embodiments. Rather, the invention can be modified to incorporate any number of variations, alterations, substitutions or equivalent arrangements not heretofore described, but which are commensurate with the spirit and scope of the invention. Additionally, while various embodiments of the invention have been described, it is to be understood that aspects of the invention may include only some of the described embodiments. Accordingly, the invention is not to be seen as limited by the foregoing description.
