The clip 26 has a first section 28 for engaging the side curtain air bag canister 20 and a second section 30 for engaging the drain tube 24, with the clip 26 having at least one wing 32 abutting the at least one bracket 22 for preventing the clip 26 from rotating on the side curtain air bag canister 20.
In the illustrated example, the vehicle 10 includes the vehicle frame 12 having the moon roof channel 14 in a roof 34. The moon roof channel 14 is configured to have a moon roof 36 therein as is well known to those skilled in the art. As used herein, moon roof and moon roof channel are the same as a sun roof and a sun roof channel. The moon roof channel 14 has a central opening 38 allowing an interior of the vehicle 10 to be open to the atmosphere. The moon roof channel 14 also includes a conduit 40 surrounding the central opening 38. The conduit 40 is configured to accept water thereon associated with having an opening in the roof 34 as is known to those skilled in the art and to direct the water to a drain opening 42 in the moon roof channel 14. In the illustrated example, the moon roof channel 14 has one drain opening 42. However, it is contemplated that the moon roof channel 14 could have any number of drain openings 42. The drain tube 24 is connected to the moon roof channel 14 at the drain opening 42 and is configured to route the water from the moon roof channel 14 to a bottom portion of the vehicle 10 for draining the water unto a road surface and not into the vehicle. In the illustrated example, the pillar 18 is the “B-pillar” of the vehicle (i.e., the pillar between the front and rear doors) and the drain tube 24 routes the water from the moon roof channel 14 and down the B-pillar. However, it is contemplated that the drain tube 24 could route water down any pillar 18 (e.g., A-pillar or B-pillar) of any vehicle (e.g., car, van, pick-up truck, etc.). The drain tube 24 can be any flexible tube for allowing a fluid to flow therethrough.
The illustrated side curtain air bag canister 20 is connected to the structural panel 16 of the vehicle 10. The side curtain air bag canister 20 holds a side curtain air bag configured to be deployed to protect a person in the vehicle 10 as is well known to those skilled in the art. The side curtain air bag canister 20 is substantially cylindrical. In the illustrated example, the brackets 22 connect the side curtain air bag canister 20 to the structural panel 16 of the vehicle 10. The brackets 22 surround the side curtain air bag canister 20. Although two brackets 22 are shown, it is contemplated that any number of brackets 22 could be employed to connect the side curtain air bag canister 20 to the structural panel 16 of the vehicle 10 (including only one bracket 22). The clip 26 connects the drain tube 24 to the side curtain air bag canister 20 for maintaining the drain tube 24 in position within the vehicle 10.
In the illustrated example, the clip 26 includes the first section 28 for engaging the side curtain air bag canister 20 and the second section 30 for engaging the drain tube 24. The clip 26 can be made of any flexible, yet resilient material (e.g., plastic) and can be formed in any manner (e.g., molding). The first section 28 of the clip 26 comprises a semi-circular canister grasping portion 44 having a first open slot 46. The semi-circular canister grasping portion 44 defines more than 180° of a circle and defines a canister accepting area 48 within the semi-circular canister grasping portion 44. As illustrated in FIG. 2, the side curtain air bag canister 20 is inserting into the canister accepting area 48 of the semi-circular canister grasping portion 44 of the first section 28 of the clip 26 by flexing the semi-circular canister grasping portion 44 on opposite sides of the first open slot 46 outward and inserting the side curtain air bag canister 20 through the first open slot 46 and into the canister accepting area 48. The semi-circular canister grasping portion 44 on opposite sides of the first open slot 46 are then released to flex back to their original configuration, thereby grasping the side curtain air bag canister 20 within the semi-circular canister grasping portion 44. It is contemplated that an interior surface 50 of the semi-circular canister grasping portion 44 could have projections thereon for assisting in grasping the side curtain air bag canister 20. Furthermore, it is contemplated that an exterior surface 52 of the semi-circular canister grasping portion 44 could have thickened portions 55 for providing strength to the first section 28.
The illustrated second section 30 of the clip 26 comprises a semi-circular drain tube grasping portion 54 having a second open slot 56. The semi-circular drain tube grasping portion 54 defines more than 180° of a circle and defines a drain tube accepting area 58 within the semi-circular drain tube grasping portion 54. As illustrated in FIG. 2, the drain tube 24 is inserting into the drain tube accepting area 58 of the semi-circular drain tube grasping portion 54 of the second section 30 of the clip 26 by flexing the semi-circular drain tube grasping portion 54 on opposite sides of the second open slot 56 outward and inserting the drain tube 24 through the second open slot 56 and into the drain tube accepting area 58. The semi-circular drain tube grasping portion 54 on opposite sides of the second open slot 56 are then released to flex back to their original configuration, thereby grasping the drain tube 24 within the semi-circular drain tube grasping portion 54. It is contemplated that an interior surface 60 of the semi-circular drain tube grasping portion 54 could have projections thereon for assisting in grasping the drain tube 24. Furthermore, it is contemplated that an exterior surface 62 of the semi-circular drain tube grasping portion 54 could have thickened portions for providing strength to the second section 30. It is further contemplated that the semi-circular drain tube grasping portion 54 on opposite sides of the second open slot 56 could have flared outward ends 66 for allowing the drain tube 24 to be easily inserted into the drain tube accepting area 58 within the semi-circular drain tube grasping portion 54.
In the illustrated example, the clip 26 includes a spanning section 68 connecting the first section 28 of the clip 26 to the second section 30 of the clip 26. However, it is contemplated that the first section 28 of the clip 26 could be directly connected to the second section 30 of the clip 26. The spanning section 68 comprises a plate 70 of material extending between the first section 28 of the clip 26 and the second section 30 of the clip 26. The spanning section 68 could also include a strut 72 connected to each side of the plate 70, the first section 28 of the clip 26 and the second section 30 of the clip 26 for providing strength and support to the clip 26.
The illustrated wings 32 of the clip 26 assist in preventing the clip 26 from rotating on the side curtain air bag canister 20. As illustrated in FIGS. 3-5, the wings 32 extend from the first section 28 of the clip 26 on one side of the first open slot 46. However, it is contemplated that the wings 32 could extend from the first section 28 of the clip 26 at a position spaced from one side of the first open slot 46. Furthermore, while two wings 32 are shown, it is contemplated that any number of wings 32 could be used (e.g., one wing, two wings, three wings, etc.). Moreover, while the wings 32 are shown as being aligned and extending from a top and bottom of the first section 28 of the clip 26 as shown in FIG. 4, the wings 32 could be spaced from each other such that one wing 32 extends upward from a first location of the first section 28 of the clip 26 in the orientation as shown in FIG. 4 and another wing 32 could extending downward from a second location of the first section 28 of the clip 26 in the orientation as shown in FIG. 4. Additionally, while the wings 32 are shown as extending substantially vertically as shown in the orientation of FIG. 4, it is contemplated that the wings 32 could be swept forward or backward (like a top view of an airplane).
In the illustrated example, the wings 32 of the clip 26 assist in preventing the clip 26 from rotating on the side curtain air bag canister 20. As shown in FIG. 2, the wings 32 overlie the brackets 22 and press downward on the brackets 22. The friction caused by the force of the wings 32 on the brackets 22 and the force of the first section 28 of the clip 26 being forced away from the side curtain air bag canister 20 (as the wings 32 will tend to cause the clip 26 to try to move the side curtain air bag canister 20 into the first open slot 46) will assist in preventing the clip 26 from rotating on the side curtain air bag canister 20. It is contemplated that the wings 32 could have a roughened surface to further assist in preventing the clip 26 from rotating on the side curtain air bag canister 20.
It is to be understood that variations and modifications can be made on the aforementioned structure without departing from the concepts of the present invention, and further it is to be understood that such concepts are intended to be covered by the following claims unless these claims by their language expressly state otherwise.
