Abstract
An apparatus (22) includes a webbing roller (32), a brake structure (80), and a support structure (62, 62). The roller (32) includes a spool (50) and a pair of axially opposite spindle structures (52) centered on an axis of rotation (53). A rotatable outer surface (54) of the spool (50) is configured to engage seat belt webbing (16). The support structure (62, 62) is configured to support the roller (32) in an ordinary operating position in which the outer surface (54) of the spool (50) is spaced radially from a braking surface (82) on the brake structure (80). The support structure (62, 62) is further configured to support the roller (32) for movement under the influence of tension in the seat belt webbing (16). Such movement of the roller (32) includes uniform movement radially from the ordinary operating position to a restrained position in which the outer surface (54) of the spool (50) engages the braking surface (82) on the brake structure (80).
