The cross sectional profile contains an inner diameter 44 defined by the fluid passageway 38. The second material fills the grooves 46 defined by the cross-sectional profile and the fluid passageway 38. The filled grooves 46 abut the engagement surface 26 creating a locking surface 40. The abutment of the engagement surface 26 and the locking surface 40 prevent the rotation of the coupling component 24 and hose 64 with respect to the mounting bracket 22.

(37) The first axis 30 is substantially perpendicular to the fluid passageway 38. The mounting bracket 22 has a first opposing surface 52 corresponding to the first end 32 of the coupling component 24. Similarly, the mounting bracket 22 has a second opposing surface 54 corresponding to the second end 34 of the coupling component 24. The intermediate portion 36 of the coupling component 24 has a first flange 56 and a second flange 58. The first and second flanges 56, 58 extend radially outward from the first axis 30, as shown in FIGS. 6-9. The void 28 in the mounting bracket 22 extends through the mounting bracket 22 and the engagement surface 26 and has an outer diameter 60. The first flange 56 engages the first opposing surface 52 of the mounting bracket 22 by extending further than the outer diameter 60 to partially enclose the void 28, and the engagement surface 26, as shown in FIG. 11. The second flange 58 engages the second opposing surface 54 of the mounting bracket 22 by extending further than the outer diameter 60 to partially enclose the void 28, and the engagement surface 26. The first and second flanges 56, 58 engage the first and second opposing surfaces, respectively, 52, 54, the void 28 and the engagement surface 26 are completely enclosed. Additionally, the first and second flanges 56, 58 have an outer diameter 62 greater than the outer diameter 60 of the engagement surface 26. This enclosing allows the fluid passageway 38 to extend from the first end 32 of the coupling component 24, through the intermediate portion 36, the void 28 and the engagement surface 26, further extending to the second end 34 of the coupling component 24 being completely sealed.

(38) A cross-sectional view of the support assembly 20 with an isotoxal star cross-sectional profile is shown in FIG. 8. The support assembly 20 is oriented such that the distance between the fluid passageway 38 and the engagement surface 26 defined by the void 28 is the first thickness T.sub.1. The first thickness T.sub.1 is filled with the second material to secure the coupling component 24 to the mounting bracket 22 creating the locking surface 40. The abutting of the locking surface 40 and the engagement surface 26 prevents the coupling component 24 and hose 64 from rotating with respect to the mounting bracket 22.

(39) A cross-sectional view of the support assembly 20 with an isotoxal star cross-sectional profile is shown in FIG. 9. The support assembly is oriented such that the distance between the fluid passageway 38 and the engagement surface 26 defined by the void 28 is the second thickness T.sub.2. The second thickness T.sub.2 is filled with the second material to secure the coupling component 24 to the mounting bracket 22 creating the locking surface 40. The abutting of the locking surface 40 and the engagement surface 26 prevents the coupling component 24 and hose 64 from rotating with respect to the mounting bracket 22.

(40) An alternative embodiment of the support assembly 20 is shown in FIG. 10. The support assembly 20 has a cross-sectional profile selected from the polygonal, curved or combination thereof. Wherein the distance between the fluid passageway 38 and the engagement surface 26 is a first thickness T.sub.1 on one side of the support assembly 20 and a second thickness T.sub.2 on the opposing side of the support assembly 20. It is to be appreciated that the possible configurations of the cross-sectional profile could have many varying thicknesses between the fluid passageway 38 and the engagement surface 26.

(41) The first and second flanges 56, 58 secure the coupling component 24 to the mounting bracket 22. The first flange 56 slopes in a direction from the first end 32 toward the mounting bracket 22 while simultaneously extending radially from the first axis 30. The second flange 58 also slopes in a direction from the second end 34 toward the mounting bracket 22 while simultaneously extending radially from the first axis 30. The flanges 56, 58 strengthen the support assembly 20 by bracing the coupling component 24 against the mounting bracket 22 and resisting any torsional force that may be experienced by the support assembly 20. It is to be appreciated, that the flanges may have a varying thickness proportional to the strength necessary for the application of the support assembly 20.

(42) The fluid passageway 38 has the inner wall 42 defined by the inner diameter 44. The thickness of the intermediate portion 36 partially filling the void 28 and engaging the engagement surface 26 varies between a first thickness T.sub.1 and a second thickness T.sub.2. As shown in FIG. 11, the radius of the engagement surface 26 varies circumferentially about the first axis 30. The outer diameter 60 of the engagement surface 26 is substantially circular, the interaction of the engagement surface 26 and the outer diameter 60 creates varying thicknesses of the second material partially filling the void 28.

(43) The varying thicknesses of the second material filling the space between the inner wall 42 of the fluid passageway 38 and the engagement surface 26 creates a connection between the mounting bracket 22 and the coupling component 24. The connection created must be a secure connection to overcome torsional forces exerted on the first and second ends 32, 34 of the coupling component 24.

(44) As shown in FIGS. 2, 3, and 6-11 the support assembly 20 is illustrated with a female connection on the first end 32 and a male connection on the second end 34. It is to be appreciated that any connector may be on either end of the support assembly 20. Additionally, the support assembly 20 may have no connector at all.

(45) Referring now to FIG. 4, the mounting bracket 22 includes a mounting feature 68. In the illustrated embodiments, the mounting feature 68 is shown as a mounting hole, however other mounting features are contemplated. It is to be appreciated that the mounting feature 68 can secure the support assembly 20 in many different fashions. For example, it could be a stud and nut configuration, a fir-tree connector configuration, a push-pin clip configuration, an expanding peg configuration, or a cable tie configuration. Additionally, the mounting bracket 22 could be sandwiched between the vehicle and another bracket to secure the support assembly 20 in place. The mounting feature 68 receives a fastener that secures the support assembly 20 to the vehicle.

(46) For illustrative purposes the first end 32 of the coupling component 24 is shown as a connector at a ninety degree angle. It is to be appreciated that the connector can be at any angle or in any orientation suitable for the application.

(47) A method of manufacturing the support assembly 20 comprises a step of forming the mounting bracket 22 and overmolding the coupling component 24 to the mounting bracket 22. The mounting bracket 22 has the engagement surface 26 defining the void 28. The coupling component 24 is formed with the first end 32, the second end 34, and the intermediate portion 36 with the intermediate portion 36 extending through and partially filling the void 28 to define the fluid passageway 38. The fluid passageway 38 is formed about the first axis 30 and through the void 28. The intermediate portion 36 is formed with the inner wall 42 facing the fluid passageway 38 and the locking surface 40 abutting the engagement surface 26 to prevent rotation of the coupling component 24 with respect to the mounting bracket 22.

(48) The step of overmolding the coupling component 24 may further include a step of forming the intermediate portion 36 of the coupling component with the first flange 56 engaging the first surface 52 of the mounting bracket 22. Furthermore, forming the intermediate portion 36 with the second flange 58 engaging the second surface 54 of the mounting bracket 22. The engaging of both the first and second flanges 56, 58 with the first and second surfaces 52, 54 of the mounting bracket 22, respectively, affixes the coupling component 24 to the mounting bracket 22.

(49) The step of overmolding the coupling component 24 may further include a step of forming the varying intermediate portion 36 having the first thickness T.sub.1 and the second thickness T.sub.2 between the fluid passageway 38 and the engagement surface 26.

(50) The invention has been described in an illustrative manner, and it is to be understood that the terminology which has been used is intended to be in the nature of words of description rather than of limitation. As is now apparent to those skilled in the art, many modifications and variations of the subject invention are possible in light of the above teachings.
