Abstract

A novel mounting bracket for an inflatable curtain is described. The mounting bracket includes a pair of attachment plates for engaging respective sides of the inflatable curtain. One plate includes an opening through which a fastener may be positioned to secure the bracket and attached inflatable curtain to the interior of a vehicle. A bushing having an inner surface and an outer surface is positioned within the opening in the mounting plate. Flanges extending from an outer surface of the bushing maintain the bushing within the opening. The outer surface of the bushing is smaller than the opening which allows the bushing to rotate freely within the bracket when a fastener is used to secure the mounting bracket to the interior of a vehicle.

17. The mounting bracket of claim 16, wherein the first edge of each attachment plate is integral with each other.

18. The mounting bracket of claim 1, further comprising a fastener attached to the inner surface of the bushing.

19. The mounting bracket of claim 1, wherein the bracket is shaped to receive a fastener having a head which is larger than a diameter of the inner surface of the bushing.

20. A mounting bracket for an inflatable curtain, comprising:

first and second attachment plates for engaging the inflatable curtain, each plate configured to engage a respective opposing surface of an inflatable curtain, at least one plate defining an opening, to permit the positioning of a fastener within the opening, wherein the first attachment plate comprises a locking tab extending from an attachment surface of the first attachment plate; and

a bushing having an inner surface and an outer surface, the bushing in rotatable communication with at least one attachment plate adjacent the bushing configured to receive a fastener, the bushing comprising a flange extending radially from the outer surface of the bushing to facilitate retention of the bushing within the opening in the attachment plate.

21. The mounting bracket of claim 20, wherein the outer surface of the bushing comprises a diameter smaller than the opening of at least one attachment plate.

22. The mounting bracket of claim 21, wherein the bushing is deformable to facilitate positioning of the bushing within the opening.

23. The mounting bracket of claim 22, wherein the bushing comprises a protrusion positioned at the inner surface to facilitate engagement of a fastener with the bushing.

24. The mounting bracket of claim 20, wherein the second attachment plate comprises a receiving orifice configured within the second attachment plate for receiving the locking tab.

25. The mounting bracket of claim 24, further comprising a fastener attached to the inner surface of the bushing.

26. The mounting bracket of claim 24, wherein the bracket is shaped to receive a fastener having a head which is larger than a diameter of the inner surface of the bushing.

27. The mounting bracket of claim 20, wherein the second attachment plate comprises a notch configured within the second attachment plate for receiving the locking tab.

28. The mounting bracket of claim 20, wherein the bushing comprises a first piece rotatably engaged to a second piece.

29. The mounting bracket of claim 28, wherein the first piece is attached to the attachment plate.
