DETAILED DESCRIPTION OF THE INVENTION
Referring to the Figures, wherein like numerals indicate corresponding parts throughout the several views, an adjustable steering column assembly is shown generally at 10 in FIG. 1. Referring to FIGS. 1 and 2, the steering column assembly 10 is for a vehicle having an instrument panel 18. The instrument panel 18 includes an instrument cluster 30 and defines a cavity 16. Typically, the cavity 16 is disposed below the instrument cluster 30.
Referring to FIGS. 4 through 7 and 9 through 10, a steering column 14 is disposed within and extends through the cavity 16 of the instrument panel 18, and defines a longitudinal axis. The steering column 14 is adjustable along the longitudinal axis between an extended position (shown in FIG. 11) and a retracted position (shown in FIG. 8), and is angularly adjustable relative to the longitudinal axis between an up position and a down position. The steering column 14 includes an outer jacket mounted to the vehicle and supports an inner jacket. A shaft is rotatably supported within the inner jacket as is well known in the art. A steering wheel 12 is coupled to the shaft of the steering column 14 as is also well known in the art.
The steering column assembly 10 includes a closeout apparatus for concealing the steering column 14 disposed between the instrument panel 18 and the steering wheel 12. The closeout apparatus includes a cover 22 having an apron 28 for mounting the cover 22 to the instrument panel 18. The cover 22 is mounted about the cavity 16 of the instrument panel 18. The cover 22 may be mounted to the instrument panel 18 with any of a variety of mounting techniques, such as with an adhesive, by mechanical fasteners, or some other suitable mounting technique. A flange 27 extends from the apron 28 along the longitudinal axis and surrounds a portion of the steering column 14. The flange 27 extends from the apron 28 to a distal end, and defines a gap d between the distal end of the flange 27 and the steering wheel 12. As shown in FIG. 4, the flange 27 may be integrally formed with the apron 28. Alternately, as shown in FIG. 5, the flange 27 may be separately mounted to the apron 28. Preferably, the apron 28 is formed of a sufficiently rigid material in order to provide adequate support for itself. However, it should be understood that the rigid material of the apron 28 is flexible enough to the steering column 14 collapses during a collision of the vehicle.
The closeout apparatus further includes a shroud 20 mounted adjacent to the steering wheel 12. The shroud 20 may be mounted to the steering wheel 12 with any of a variety of mounting techniques, such as with an adhesive, with mechanical fasteners, or some other suitable mounting technique. The shroud 20 surrounds a portion of the flange 27 of the cover 22 and also surrounds a portion of the steering column 14. The shroud 20 cooperates with the flange 27 to conceal the gap d between the distal end of the flange 27 and the steering wheel 12.
As shown in FIG. 5, the steering column assembly 10 may include a noise dampening material 21 disposed on the shroud 20 for improving the acoustic properties of the steering column assembly 10. In a preferred embodiment, the noise dampening material 21 is disposed on an inner surface of the shroud 20 to hide the noise dampening material 21 from view. As shown, the noise dampening material 21 is disposed axially on the shroud 20 between the shroud 20 and the apron 28. It should be understood that the noise dampening material 21 may also be disposed on the inner surface of the shroud 20 not adjacent the apron 28. As another alternative embodiment, the noise dampening material 21 could be disposed on an outer surface of the flange 27. Preferably, the noise dampening material 21 may be of a material such as foam or felt. However, it should be understood that the noise dampening material 21 may be formed from some other suitable acoustic dampening material.
The flange 27 includes an upper portion 25 and a lower portion 26. Each of the upper portion 25 and the lower portion 26 has a predetermined length along the longitudinal axis at least equal to a length of the adjustment between the extended position and the retracted position. The shroud 20 continuously surrounds a portion of the flange 27 and is spaced laterally from the flange 27 during the adjustment between the extended position and the retracted position and the up position and the down position for continuously concealing the gap d between the flange 27 and the steering column 14 without engaging the flange 27. In other words, the shroud 20 does not contact the flange 27, regardless of the position of the steering column 14 and the steering wheel 12.
The predetermined lengths of the upper portion 25 and the lower portion 26 of the flange 27 are substantially equal, and are greater than the length of the adjustment between the extended position and the retracted position. Preferably, the predetermined lengths are at least 50 mm. However, the predetermined lengths may also be at least 60 mm, and it should be understood that the predetermined length may include some other length not specifically enumerated herein.
Preferably, the shroud 20 and the cover 22 are formed of a polymeric material. However, it should be understood that the shroud 20 and the cover 22 may be formed from some other suitable material.
FIGS. 6 and 7 show the relationship of the shroud 20 and the flange 27 when the steering wheel 12 is at minimum extension. Referring to FIG. 6, the shroud 20 is shown overlapping the flange 27 when the steering wheel 12 is at full up tilt and at minimum extension, i.e., in the retracted position. FIG. 7 shows the shroud 20 overlapping the flange 27 when the steering wheel 12 is fully tilted down and at minimum extension. FIG. 8 shows how the steering column 14 is fully covered by the shroud 20 and the cover 22 when the steering wheel 12 is in the retracted position
FIGS. 9 and 10 show the relationship of the shroud 20 and the flange 27 when the steering wheel 12 is at maximum extension. In FIG. 9 the shroud 20 is shown overlapping the flange 27 when the steering wheel 12 is at full up tilt and at maximum extension. Referring to FIG. 10, the shroud 20 is shown overlapping the flange 27 when the steering wheel 12 is at full down tilt and at maximum extension. FIG. 11 shows how the steering column 14 is fully covered by the shroud 20 and the cover 22 provide when the steering wheel 12 is in the extended position.
In the embodiment shown in FIGS. 8 and 11, the cover 22 includes an upper piece 23 and a lower piece 24 with the upper piece 23 defining the upper portion 25 of the flange 27 and the lower piece 24 defining the lower portion 26 of the flange 27. The upper piece 23 and the lower piece 24 are dimensionally similar with each of the pieces 23, 24 covering substantially half of the cavity 16. The shroud 20 also includes two pieces with each of the two pieces surrounding a portion of the flange 27. However, it should be understood that the shroud 20 and the cover 22 may each be unitary pieces, i.e., the shroud 20 is a unitary piece and the cover 22 is a unitary piece, and the scope of the invention should not be limited to require the shroud 20 and the cover 22 to include separate pieces.
The foregoing invention has been described in accordance with the relevant legal standards; thus, the description is exemplary rather than limiting in nature. Variations and modifications to the disclosed embodiments may become apparent to those skilled in the art and do come within the scope of the invention. Accordingly, the scope of legal protection afforded this invention can only be determined by studying the following claims.
