Abstract

One embodiment of the present invention is a belt guide apparatus (14) for an enhanced seatbelt restraint system (10) for a vehicle. The belt guide apparatus (14) includes a pivotal fastener (56) for attaching the belt guide apparatus (14) to a vehicle structure (20). The pivotal fastener (56) includes an interface portion (42) extending therefrom for supporting a belt (12) extending through the belt guide apparatus (14). Also, the pivotal fastener (56) is utilized for moving the belt guide apparatus (14) in three or more directions for maintaining the belt (12) substantially flat against the interface portion (42). Moreover, the interface portion (42) has a biasing mechanism (64) disposed adjacent thereto for pressing the belt (12) substantially flat against the interface portion (42).

Claims

1. A belt guide member for an enhanced seatbelt restraint system of a vehicle, comprising:

a pivotal fastener for attachment to a vehicle structure;

an interface portion extending from said pivotal fastener for supporting a belt extending through the belt guide member; and

a biasing mechanism disposed adjacent to said interface portion for pressing said belt substantially flat against said interface portion;

wherein said pivotal fastener moves the belt guide member in at least three directions for maintaining said belt substantially flat against said interface portion.

2. The belt guide member recited in claim 1 wherein said pivotal fastener and said vehicle structure comprise a ball-and-socket coupling for moving the belt guide member in said at least three directions.

3. The belt guide member recited in claim 1 wherein said interface portion has a supporting surface that is contoured for biasing said belt toward a center portion of said interface portion.

4. The belt guide member recited in claim 3 wherein said interface portion has opposing end portions that are thicker than said center portion of said interface portion.

5. The belt guide member recited in claim 1 further comprising:

a ring construction with a cross member integrated therein for mounting said biasing mechanism thereto.

6. The belt guide member recited in claim 5 wherein said biasing mechanism includes a housing coupled to said cross member and at least one resilient member coupled between said housing and said cross member for forcing said housing onto said belt and maintaining said belt substantially flat against said interface portion.

7. The belt guide member recited in claim 6 wherein said housing has a channel formed therethrough for receiving said cross member.

8. The belt guide member recited in claim 7 wherein said channel is sized for moving said biasing mechanism between a belt-flattening configuration and an offset configuration.

9. The belt guide member recited in claim 6 wherein said housing has a belt-adjusting surface contoured for substantially flattening said belt against a supporting surface of said interface portion of said belt member guide.

10. The belt guide member recited in claim 9 wherein said supporting surface is sized for substantially receiving said belt-adjusting surface.

11. A belt guide member for an enhanced seatbelt restraint system of a vehicle, comprising:

a ring construction with a cross member integrated therein;

a pivotal fastener integrated in said ring construction for attaching the belt guide member to a vehicle structure;

an interface portion being a roller member that is rotatably coupled to said ring construction, said roller member utilized for supporting a belt extending through the belt guide member; and

a biasing mechanism disposed adjacent to said cross member for pressing said belt substantially flat against said interface portion;

wherein said pivotal fastener moves the belt guide member in at least three directions for maintaining said belt substantially flat against said interface portion.

12. The belt guide member recited in claim 11 wherein said pivotal fastener and said vehicle structure comprise a ball-and-socket coupling for moving the belt guide member in said at least three directions.

13. The belt guide member recited in claim 11 wherein said roller member has a supporting surface that is contoured for biasing said belt toward a center portion of said roller member.

14. The belt guide member recited in claim 13 wherein said roller member has opposing end portions that are thicker than said center portion of said roller member.

15. The belt guide member recited in claim 11 wherein said biasing mechanism includes a housing coupled to said cross member and at least one resilient member coupled between said housing and said cross member for forcing said housing onto said belt and maintaining said belt substantially flat against a supporting surface of said roller member.

16. The belt guide member recited in claim 15 wherein said housing has a channel formed therethrough for receiving said cross member.

17. The belt guide member recited in claim 15 wherein said housing has a belt adjusting surface contoured for substantially flattening said belt against a supporting surface of said roller member of said belt member guide.

18. The belt guide member recited in claim 17 wherein said supporting surface of said roller member is sized for substantially receiving said belt-adjusting surface of said biasing mechanism.

19. An enhanced seatbelt restraint system for a vehicle, comprising:

an inflatable belt;

an inflator device coupled to said inflatable belt;

at least one crash sensor coupled to said inflator device for actuating said inflator device to inflate said inflatable belt;

a belt guide member pivotally coupled to a vehicle structure, said belt guide member utilized for supporting said inflatable belt and minimizing an edge loading on said inflatable belt;

wherein said belt guide member includes a pivotal fastener for attachment to said vehicle structure;

wherein said belt guide member further includes an interface portion extending from said pivotal fastener for supporting said inflatable belt extending through said belt guide member; and

wherein said belt guide member further includes a biasing mechanism that is movable between a belt-flattening configuration and an offset configuration;

wherein said biasing member in said belt-flattening configuration presses said inflatable belt substantially flat against said roller member;

wherein said biasing member in said offset configuration is offset a predetermined distance from said roller member for providing room for said inflatable belt to inflate;

wherein said pivotal fastener moves the belt guide member in at least three directions for maintaining said belt substantially flat against said interface portion.

20. The enhanced seatbelt restraint system recited in claim 19 wherein inflatable belt is comprised of at least one of an inflatable shoulder belt portion and an inflatable lap belt portion.
