Abstract

An automobile roof rail system includes a rail having opposed first and second side walls defining a cavity between the first and second side walls. A retention feature is provided with each of the first side wall and the second side wall. A resilient material first seal is engaged at a first end with the retention feature of the first side wall, and a resilient material second seal is engaged at a first end with the retention feature of the second side wall. A living hinge separates a free second end of each of the first seal and the second seal from the first end. The free second end of each of the first seal and the second seal is directed into the cavity in an as-molded condition.

First claim

What is claimed is:

1. An automobile roof rail system, comprising:
a rail having a first side wall and a second side wall joined by a cross member with a cavity positioned between the first side wall and the second side wall and the cross member and extending downward from and in line with the first side wall and the second side wall;
a retention feature integrally provided with each of the first side wall and the second side wall, the retention feature of each of the first side wall and the second side wall having an engagement member defining a male member formed within the cavity below the cross member and extending into the cavity and facing each other and facing into the cavity, the male member being thinner where connected to the first side wall or the second side wall than in a portion of the male member spaced away from the first side wall or the second side wall;
first and second resilient material seals including a female cavity having a shape matching an outer surface of the male member, wherein the male member is frictionally received in the female cavity of the seals, the seals engaged at a first end with the male member of the retention feature of the first side wall and the second side wall, the first seal frictionally and positively engaged with the first side wall and the second seal frictionally and positively engaged with the second side wall, both seals positioned entirely between the first side wall and the second side wall and facing each other; and
a living hinge separating a free second end of each seal from the first end of each seal, the free second end of each seal freely positioned in the cavity.

2. The automobile roof rail system of claim 1 , wherein the free second end of each seal is freely suspended in the cavity after engaged coupling of the first end of the seal with the retention feature, and prior to installation of the rail onto a vehicle roof raised gusset.

3. The automobile roof rail system of claim 2 , wherein the rail when positioned over the raised gusset of a roof portion of a vehicle in a rail installed position on the roof portion receives the raised gusset within the cavity, the raised gusset causing the second end of the seal to deflect thereby contacting both the roof portion and the gusset in the rail installed position.

4. The automobile roof rail system of claim 1 , wherein the first and second side wall includes an end face spaced freely away from a roof portion of a vehicle with the rail in a rail installed position on a vehicle roof portion.

5. The automobile roof rail system of claim 4 , wherein no portion of the seals extend outwardly with respect to a vertical plane contacting an outer corner of the first and second side walls at the end face.

6. The automobile roof rail system of claim 1 , wherein the seals comprise a resilient material having a first durometer in the first end and a second durometer lower than the first durometer in the second end.

7. The automobile roof rail system of claim 1 , wherein the male member has a rounded shape.

8. The automobile roof rail system of claim 1 , wherein the seals contact an inner surface of the side wall above and below the male member.

9. The automobile roof rail system of claim 1 , wherein the seals do not contact the cross member.

10. An automobile roof rail system, comprising:
a rail having opposed first and second side walls joined by a cross member defining a cavity between the first and second side walls and the cross member and extending downward from and in line with the first side wall and the second side wall;
a retention feature provided with each of the first side wall and the second side wall below the cross member and facing into the cavity and facing each other;
an engagement member of the retention feature defining a male member formed within the cavity below the cross member and extending into the cavity and facing each other and facing into the cavity, the male member being thinner where connected to the first side wall or the second side wall than in a portion of the male member spaced away from the first side wall or the second side wall;
a resilient material first seal matingly engaged at a first end with the engagement member of the retention feature of the first side wall, and a resilient material second seal matingly engaged at a first end with the engagement member of the retention feature of the second side wall, each of the first seal and the second seal including a female cavity having a shape matching an outer surface of the male member; and
each of the first seal and the second seal having a free second end, the free second end of each of the first seal and the second seal facing each other and directed into the cavity in an as-molded condition after mating engagement onto the retention feature, but prior to installation of the rail onto a vehicle roof portion.

11. The automobile roof rail system of claim 10 , wherein each of the first seal and the second seal include a living hinge separating the free second end of each of the first seal and the second seal from the first end of the first seal and the second seal.

12. The automobile roof rail system of claim 11 , wherein each of the first seal and the second seal include a transition portion which transitions in thickness from the first end to the second end.

13. The automobile roof rail system of claim 12 , wherein each of the first seal and the second seal include an upwardly curved deflecting end connected to the transition portion using the living hinge.

14. The automobile roof rail system of claim 10 , wherein the second end of the first and second seal defines a bulbous shape.

15. The automobile roof rail system of claim 10 , wherein the first and second seal includes a deflecting end proximate to the second end connected to the first end by a transition portion which is thinner than the first end and the second end.

16. The automobile roof rail system of claim 10 , wherein the male member of the first side wall is integrally connected to the first side wall and the male member of the second side wall is integrally connected to the second side wall.

17. The automobile roof rail system of claim 10 , wherein the second end of the first and second seal defines a hook-shape.

18. An automobile roof rail system, comprising:
a metal rail having opposed first and second side walls joined by a cross member defining a cavity between the first and second side walls and under the cross member and extending downward from and in line with the first side wall and the second side wall;
a retention feature provided with each of the first side wall and the second side wall below the cross member and facing into the cavity and facing each other;
an engagement member of the retention feature defining a male member formed within the cavity below the cross member and extending into the cavity and facing each other and facing into the cavity, the male member being thinner where connected to the first side wall or the second side wall than in a portion of the male member spaced away from the first side wall or the second side wall;
a resilient material first seal matingly engaged at a first end with the retention feature of the first side wall, and a resilient material second seal matingly engaged at a first end with the retention feature of the second side wall;
each of the first seal and the second seal including a female cavity having a shape matching an outer surface of the male member;
each of the first seal and the second seal having a living hinge separating a free second end of each of
