Description
RETENTION BRACKET FOR STEERING COLUMN MEMBER
FIELD OF THE INVENTION
This invention relates to a retention bracket for coupling or securing an object to another object at a mounting location, or most preferably a steering column member to a vehicle cross-support member. The invention further relates to a vehicle steering wheel arrangement which includes a plurality of retention bracket coupled to mounting locations provided on a vehicle cross-support member.
BACKGROUND OF THE INVENTION
In the automobile industry, vehicle cross-support members, crossbeams, cross car beams, and other similar components (collectively referred hereinafter as "vehicle cross-support members" or "cross-support members") are utilized as part of the vehicular body structure. The vehicle cross-support member normally spans between or fastened to a pair of laterally disposed vertical pillars, or A-pillars, in the region below the windscreen, and between a forward engine compartment and a rearward passenger compartment, so as to extend in a direction transverse to the length of an automobile. As part of a motor vehicle body, the cross-support member provides for cross car stiffness and rigidity against for example side load impacts.
Located forwardly of the driver and the front-row passenger, the cross-support member also supports or provides mounting surfaces for various vehicle components, including an instrument panel, a glove and/or storage compartment, a center console, a dashboard and a steering column member. Although direct attachment may be possible, various attachment devices or assemblies could be utilized on the cross-support member to effect attachment of such vehicle components. The attachment devices and assemblies are preferably designed such that the noise and vibrations transferring from the vehicle engine, drivetrain, transmission or any other moving parts are reduced for optimal passenger comfort. Reduction of weight and production costs are also of important consideration in designing such attachment devices and assemblies.
A number of attachment assemblies for attaching the steering column member to the cross-support member are known. United States Patent No. 8,029,045 to Merkle discloses an integrated cross-support member design having an attachment device of a three-dimensional ribbed structure fastened to a crossbeam body. The attachment device of Merkle includes a plurality of vertically oriented blanks coupled to the crossbeam body in a distributed, side-by-side manner over a partial length thereof, and in an orientation extending transverse to the longitudinal axis of the crossbeam body to form a ribbed structure. Merkle describes that the ribbed structure provides multiple mounting locations for attachment elements, such as bushes and threaded pins, for attaching a vehicle component or a steering column to the crossbeam body. Specifically, Merkle describes that the attachment elements are coupled to two adjacent blanks in the gap

Reduction of weight and production costs are also of important consideration in designing such attachment devices and assemblies.
A number of attachment assemblies for attaching the steering column member to the cross-support member are known. United States Patent No. 8,029,045 to Merkle discloses an integrated cross-support member design having an attachment device of a three-dimensional ribbed structure fastened to a crossbeam body. The attachment device of Merkle includes a plurality of vertically oriented blanks coupled to the crossbeam body in a distributed, side-by-side manner over a partial length thereof, and in an orientation extending transverse to the longitudinal axis of the crossbeam body to form a ribbed structure. Merkle describes that the ribbed structure provides multiple mounting locations for attachment elements, such as bushes and threaded pins, for attaching a vehicle component or a steering column to the crossbeam body. Specifically, Merkle describes that the attachment elements are coupled to two adjacent blanks in the gap
2 between the blanks. Merkle further provides that for rigidity and stiffness, a bracing bar and rigid linking elements (to connect free ends of adjacent blanks) could be utilized.
Merkle suggests that such arrangements provide for improved stiffness and strength, as well as improved maximum mechanical load which may be placed on the attachment device. Merkle further suggests that the open structure of the attachment device allows for improved weight reduction, when compared to other known devices incorporating a closed structure.
It is believed that the attachment device of Merkle may suffer the disadvantages in that the individual blanks could be prone to transferring noise and vibrations from the engine compartment to the driver and the passenger compartment. Furthermore, the use of multiple blanks which must be fastened individually to the crossbeam body may require greater fabrication precision, and involve greater complexity and manufacturing costs. The vertically oriented blanks may also pose a serious safety concern for the driver, especially in the context of a head-on collision at higher speeds.
SUMMARY OF THE INVENTION
One possible non-limiting object of the present invention is to provide a retention bracket for coupling a steering column member to a cross-support member, and which is for improving noise, vibration and harshness ("NVH") performance.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Reference is made to Figure 1 which shows a side view of a retention bracket for use with a vertically oriented coupling plate 20 in coupling a vehicle steering column member 100 to a vehicle cross-support member 200 in accordance with a preferred embodiment of the present invention. As will be described, the retention bracket 10 includes a load bearing mounting shoe 40 and an elongated fastening cylinder 60. For greater clarity, Figure 2 separately illustrates a fully assembled retention bracket 10 in which the shoe 40 and the cylinder 60 are welded together with the coupling plate 20 to form a single integral unit.
As seen in Figure 3, the coupling plate 20 has a generally rectangular backing portion 22 which is formed having a generally planar configuration along its lower portion, and which may have formed therein one or more stamped reinforcing ribs 24 for improved structural rigidity. The backing portion 22 defines a forwardly oriented weldable surface 26 and a rearward steering column mounting surface (not shown) opposed to the weldable surface 26. The backing portion 22 further defines in the lower portion an aperture 28 offset towards a lateral edge 30, and which extends between the weldable surface 26 and the opposed rearward surface. A rearwardly projecting cradling lip 32 is integrally formed at a bottom edge of the coupling plate 20.
Although not strictly limited, the coupling plate 20 preferably extends vertically between about 5 cm and about 15 cm in length and between about 2 cm and about 7 cm in width, and more preferably between about 7 cm and about 12 cm in length and between about 3 cm and about 5 cm in width. The coupling plate 20 preferably has a thickness between about 0.1 cm and 1 cm.
Reference is made to Figures 4 which shows a perspective view of the load bearing mounting shoe 40. The mounting shoe 40 is formed from a single stamped metal piece, and most preferably is comprised of cold-formed or raw-formed steel.
The mounting shoe 40 includes a pair of generally parallel gusset plates 42, 44 each extending forwardly between about 2 cm and about 7 cm from their respective rear edges 43, 45 (shown in Figure 5). The gusset plates 42, 44 are laterally spaced between about 1 cm and 6 cm, and are integrally merged at their forward edges with a transverse forward end plate 46. The forward end plate 46 is angled forwardly towards an upper edge at an inclination angle selected at between about 2 and 20 , and preferably at about 5 , such that with the retention bracket 10 mated to the cross-support member 200, the end plate 46 extends further forwardly on the cross-support member 200 than on the fastening cylinder 60. The respective upper edges of the gusset plates 42, 44 and the forward end plate 46 cooperatively define a generally planar, continuous U-shaped upper rim 48.
The gusset plates 42, 44 and the forward end plate 46 further cooperatively define an open interior 50. The gusset plate 42 includes a lowermost flange 52 extending along a lower portion thereof, so as to project inwardly between about 0.5 cm and about 4 cm towards the open interior 50 and the gusset plate 44, to an inner end 54. The inner end 54 does not fully extend to contact the gusset plate 44, such that a cylinder receiving channel 56 is defined therebetween.
In an alternative embodiment, the gusset plate 44 includes the lowermost flange 52 extending along its lower portion, and projecting inwardly towards the open interior 50 and the gusset plate 42.
Reference is made to Figure 6 which illustrates a perspective view of the elongated fastening cylinder 60 in accordance with a preferred embodiment of the present invention. The fastening cylinder 60 includes a cylindrical body 61 defining an axially extended hollow interior 62 and an outer peripheral surface 63 which is circular in cross section normal to the axis of the cylinder 60. The cylindrical body 61 includes at an axial end a reduced diameter portion 64 integrally joined thereto with a shoulder 66. As best seen in Figure 7, the rearward end of the cylindrical body 61 and the reduced diameter portion 64 define an internally threaded bore surface 68 which extends axially to open to a rearward end of the reduced diameter portion 64. The cylindrical body 61 preferably = CA 02834010 2013-11-21 extends axially between about 3 cm and about 10 cm from the shoulder 66. The outer diameter of the out peripheral surface 63 is preferably between about 1 cm and about 4 cm, and larger than that of the reduced diameter portion 64 which is preferably between about 0.5 cm and about 2.5 cm. The reduced diameter portion 64 preferably extends rearwardly between about 0.1 cm and about 0.5 cm.
For assembly, the reduced diameter portion 64 of the fastening cylinder 60 is inserted into the aperture 28 of the coupling plate 20, such that the shoulder 66 is seated around a circumferential edge of the aperture 28. With the reduced diameter portion 64 received in the aperture 28, the fastening cylinder 60 is secured to the weldable surface 26 by weldments extending circumferentially about the outermost circumference of the shoulder 66. With the upper rim 48 oriented upwardly, the rear edges 43, 45 of the gusset plates 42, 44 are positioned in juxtaposition with the weldable surface 26, such that the rear edges 43, 45 are aligned generally parallel to the lateral edge 30, and the inner end 54 of the lowermost flange 52 and the bottom edge of the gusset plate 44 are adjacent to or in physical contact with the outer peripheral surface 63. Once the fastening cylinder 60 is oriented in position within the cylinder receiving channel 56 as such, to complete assembly the rear edges 43, 45 are then welded to the weldable surface 26 and the outer peripheral surface 63 to the inner end 54 and the bottom edge of the gusset plate 44.
As shown in Figures 1 and 2, the fastening cylinder 60 extends past a lower edge of the forward end plate 46, so as to provide an additional weldable interface or abutting contact between the fastening cylinder 60 and the mounting shoe 40 for improved load distribution. Furthermore, in the fully assembled form the reduced diameter portion 64 does not protrude past the rearward mounting surface (best shown in Figure 9), such that the rearward surface is maintained as a generally planar surface.
It is to be appreciated that a person skilled in the art would readily appreciate other possible ways of preparing or assembling the retention bracket 10. For example, the fastening cylinder 60 may be welded to the mounting shoe 40 first to form the retention bracket 30, and the retention bracket 30 can then be welded to the coupling plate 20. Alternatively, the mounting shoe 40 may be welded to the coupling plate 20 first, followed by welding of the fastening cylinder 60 to the coupling plate 20 and the mounting shoe 40.
In operation, to mount the steering column member 100 in an automobile, the fully assembled retention bracket 10, together with the coupling plate 20 are welded to the vehicle cross-support member 200 at a mounting location having a rearwardly oriented mounting surface (not shown) and a downwardly oriented mounting surfaces 210 as seen in Figure 8. In particular, an upper portion of the weldable surface 26 of the coupling plate 20 is welded to the rearwardly oriented mounting surface, and the upper rim 48 of the mounting shoe 40 to the downwardly oriented mounting surface 210. When welded to the mounting location, the internally threaded bore surface 68 of the fastening cylinder 60 is in position to receive an externally threaded end of an attachment bolt in securing the steering column member 100 thereto.
It has been appreciated that the combination of the mounting shoe 40 and the fastening cylinder 60 of the invention may provide for improved load distribution and NVH performance of the steering column member 100 mounted with the retention bracket 10.
Reference is made to Figure 9 which shows a perspective view of a preferred vehicle steering wheel mounting arrangement 300 which includes the vehicle cross-support member 200 and a pair of longitudinally spaced retention brackets 410, 510 and associated vertically oriented coupling plates 420, 520 welded to the cross-support member 200. As seen in Figure 10, respective apertures 428, 528 defined by the coupling plates 420, 520 are offset towards a center steering column mounting area 320, such that respective lowermost flanges 452, 552 extend inwardly towards the same. It has been appreciated that such arrangement of the retention brackets 410, 510, and the inwardly extending lowermost flanges 452, 552 may provide for further improved load distribution and NVH performance.
It is to be appreciated that although the retention bracket 10, 410, 510 has been described with respect to a most preferred use with the coupling plate 20, 420, 520 in mounting the steering column member 100 to the vehicle cross-support member 200, the retention bracket 10, 410, 510 is not or intended to be limited solely to such use. In particular, the retention bracket 10, 410, 510 could also permit uses in mounting or coupling other mechanical components or objects at a mounting location with an attachment bolt, where the mounting location most preferably includes a generally planar mounting surface oriented at an angle to another mounting surface.
Furthermore, it is to be appreciated that the retention bracket 10, 410, 510 does not necessarily require the preferred mounting orientations illustrated in Figures 1, 9 and 10.
Specifically, in alternative embodiments, the reinforcing cylinder may be oriented vertically, horizontally or at any other angles therebetween when welded or secured at a mounting location.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Reference is made to Figure 1 which shows a side view of a retention bracket for use with a vertically oriented coupling plate 20 in coupling a vehicle steering column member 100 to a vehicle cross-support member 200 in accordance with a preferred embodiment of the present invention. As will be described, the retention bracket 10 includes a load bearing mounting shoe 40 and an elongated fastening cylinder 60. For greater clarity, Figure 2 separately illustrates a fully assembled retention bracket 10 in which the shoe 40 and the cylinder 60 are welded together with the coupling plate 20 to form a single integral unit.
As seen in Figure 3, the coupling plate 20 has a generally rectangular backing portion 22 which is formed having a generally planar configuration along its lower portion, and which may have formed therein one or more stamped reinforcing ribs 24 for improved structural rigidity. The backing portion 22 defines a forwardly oriented weldable surface 26 and a rearward steering column mounting surface (not shown) opposed to the weldable surface 26. The backing portion 22 further defines in the lower portion an aperture 28 offset towards a lateral edge 30, and which extends between the weldable surface 26 and the opposed rearward surface. A rearwardly projecting cradling lip 32 is integrally formed at a bottom edge of the coupling plate 20.
Although not strictly limited, the coupling plate 20 preferably extends vertically between about 5 cm and about 15 cm in length and between about 2 cm and about 7 cm in width, and more preferably between about 7 cm and about 12 cm in length and between about 3 cm and about 5 cm in width. The coupling plate 20 preferably has a thickness between about 0.1 cm and 1 cm.
Reference is made to Figures 4 which shows a perspective view of the load bearing mounting shoe 40. The mounting shoe 40 is formed from a single stamped metal piece, and most preferably is comprised of cold-formed or raw-formed steel.
The mounting shoe 40 includes a pair of generally parallel gusset plates 42, 44 each extending forwardly between about 2 cm and about 7 cm from their respective rear edges 43, 45 (shown in Figure 5). The gusset plates 42, 44 are laterally spaced between about 1 cm and 6 cm, and are integrally merged at their forward edges with a transverse forward end plate 46. The forward end plate 46 is angled forwardly towards an upper edge at an inclination angle selected at between about 2 and 20 , and preferably at about 5 , such that with the retention bracket 10 mated to the cross-support member 200, the end plate 46 extends further forwardly on the cross-support member 200 than on the fastening cylinder 60. The respective upper edges of the gusset plates 42, 44 and the forward end plate 46 cooperatively define a generally planar, continuous U-shaped upper rim 48.
The gusset plates 42, 44 and the forward end plate 46 further cooperatively define an open interior 50. The gusset plate 42 includes a lowermost flange 52 extending along a lower portion thereof, so as to project inwardly between about 0.5 cm and about 4 cm towards the open interior 50 and the gusset plate 44, to an inner end 54. The inner end 54 does not fully extend to contact the gusset plate 44, such that a cylinder receiving channel 56 is defined therebetween.
In an alternative embodiment, the gusset plate 44 includes the lowermost flange 52 extending along its lower portion, and projecting inwardly towards the open interior 50 and the gusset plate 42.
Reference is made to Figure 6 which illustrates a perspective view of the elongated fastening cylinder 60 in accordance with a preferred embodiment of the present invention. The fastening cylinder 60 includes a cylindrical body 61 defining an axially extended hollow interior 62 and an outer peripheral surface 63 which is circular in cross section normal to the axis of the cylinder 60. The cylindrical body 61 includes at an axial end a reduced diameter portion 64 integrally joined thereto with a shoulder 66. As best seen in Figure 7, the rearward end of the cylindrical body 61 and the reduced diameter portion 64 define an internally threaded bore surface 68 which extends axially to open to a rearward end of the reduced diameter portion 64. The cylindrical body 61 preferably = CA 02834010 2013-11-21 extends axially between about 3 cm and about 10 cm from the shoulder 66. The outer diameter of the out peripheral surface 63 is preferably between about 1 cm and about 4 cm, and larger than that of the reduced diameter portion 64 which is preferably between about 0.5 cm and about 2.5 cm. The reduced diameter portion 64 preferably extends rearwardly between about 0.1 cm and about 0.5 cm.
For assembly, the reduced diameter portion 64 of the fastening cylinder 60 is inserted into the aperture 28 of the coupling plate 20, such that the shoulder 66 is seated around a circumferential edge of the aperture 28. With the reduced diameter portion 64 received in the aperture 28, the fastening cylinder 60 is secured to the weldable surface 26 by weldments extending circumferentially about the outermost circumference of the shoulder 66. With the upper rim 48 oriented upwardly, the rear edges 43, 45 of the gusset plates 42, 44 are positioned in juxtaposition with the weldable surface 26, such that the rear edges 43, 45 are aligned generally parallel to the lateral edge 30, and the inner end 54 of the lowermost flange 52 and the bottom edge of the gusset plate 44 are adjacent to or in physical contact with the outer peripheral surface 63. Once the fastening cylinder 60 is oriented in position within the cylinder receiving channel 56 as such, to complete assembly the rear edges 43, 45 are then welded to the weldable surface 26 and the outer peripheral surface 63 to the inner end 54 and the bottom edge of the gusset plate 44.
As shown in Figures 1 and 2, the fastening cylinder 60 extends past a lower edge of the forward end plate 46, so as to provide an additional weldable interface or abutting contact between the fastening cylinder 60 and the mounting shoe 40 for improved load distribution. Furthermore, in the fully assembled form the reduced diameter portion 64 does not protrude past the rearward mounting surface (best shown in Figure 9), such that the rearward surface is maintained as a generally planar surface.
It is to be appreciated that a person skilled in the art would readily appreciate other possible ways of preparing or assembling the retention bracket 10. For example, the fastening cylinder 60 may be welded to the mounting shoe 40 first to form the retention bracket 30, and the retention bracket 30 can then be welded to the coupling plate 20. Alternatively, the mounting shoe 40 may be welded to the coupling plate 20 first, followed by welding of the fastening cylinder 60 to the coupling plate 20 and the mounting shoe 40.
In operation, to mount the steering column member 100 in an automobile, the fully assembled retention bracket 10, together with the coupling plate 20 are welded to the vehicle cross-support member 200 at a mounting location having a rearwardly oriented mounting surface (not shown) and a downwardly oriented mounting surfaces 210 as seen in Figure 8. In particular, an upper portion of the weldable surface 26 of the coupling plate 20 is welded to the rearwardly oriented mounting surface, and the upper rim 48 of the mounting shoe 40 to the downwardly oriented mounting surface 210. When welded to the mounting location, the internally threaded bore surface 68 of the fastening cylinder 60 is in position to receive an externally threaded end of an attachment bolt in securing the steering column member 100 thereto.
It has been appreciated that the combination of the mounting shoe 40 and the fastening cylinder 60 of the invention may provide for improved load distribution and NVH performance of the steering column member 100 mounted with the retention bracket 10.
Reference is made to Figure 9 which shows a perspective view of a preferred vehicle steering wheel mounting arrangement 300 which includes the vehicle cross-support member 200 and a pair of longitudinally spaced retention brackets 410, 510 and associated vertically oriented coupling plates 420, 520 welded to the cross-support member 200. As seen in Figure 10, respective apertures 428, 528 defined by the coupling plates 420, 520 are offset towards a center steering column mounting area 320, such that respective lowermost flanges 452, 552 extend inwardly towards the same. It has been appreciated that such arrangement of the retention brackets 410, 510, and the inwardly extending lowermost flanges 452, 552 may provide for further improved load distribution and NVH performance.
It is to be appreciated that although the retention bracket 10, 410, 510 has been described with respect to a most preferred use with the coupling plate 20, 420, 520 in mounting the steering column member 100 to the vehicle cross-support member 200, the retention bracket 10, 410, 510 is not or intended to be limited solely to such use. In particular, the retention bracket 10, 410, 510 could also permit uses in mounting or coupling other mechanical components or objects at a mounting location with an attachment bolt, where the mounting location most preferably includes a generally planar mounting surface oriented at an angle to another mounting surface.
Furthermore, it is to be appreciated that the retention bracket 10, 410, 510 does not necessarily require the preferred mounting orientations illustrated in Figures 1, 9 and 10.
Specifically, in alternative embodiments, the reinforcing cylinder may be oriented vertically, horizontally or at any other angles therebetween when welded or secured at a mounting location.
While the invention has been described with reference to preferred embodiments, the invention is not or intended by the applicant to be so limited. A person skilled in the art would readily recognize and incorporate various modifications, additional elements and/or different combinations of the described components consistent with the scope of the invention as described herein.
