Abstract
A webbing guide for a vehicle safety comprises a guide surface in the form of a generally cylindrical bar (6) which has a continuous outer surface over which seat belt webbing passes in use following an upside-down U-shaped path. The surface comprises a top portion and two side portions (8) on either side of the top portion, and the top portion and at least one of the side portions are shaped so as to present a countered surface to the seat belt webbing. Preferably, the central area (7) of the top portion is raised, and the central area (9) of one or both side portions (8), is recessed, but the opposite contour arrangement could be provided with the central area of the top portion recessed and the central area of one or both side portions raised.
Claims5
A seat belt system including a webbing guide and seat belt webbing comprising:
- a generally cylindrical bar having a continuous outer guide surface over which the seat belt webbing passes in use, the outer guide surface having, in consecutive order in relation to a direction of travel of the webbing:
- a first or back side portion,
- a top portion, and
- a second or front side portion;
- wherein the outer guide surface has a central region and two outer regions separated by and adjacent to the central region and the outer guide surface includes a first contour, as viewed perpendicular to the direction of travel of the webbing, the first contour being situated in a central region of the top portion, and a second contour, opposite to the first contour as viewed perpendicular to the direction of travel of the webbing, the second contour being in the central region of the first or back side portion of the bar, wherein one of the first and the other contour comprises a raised portion, and the second contour comprises a recessed portion, such that each fibre of the belt webbing contact the outer guide surface of the bar for a substantially identical distance measured in a circumferential sense around the bar.
