A vehicle seat belt system (10) includes a length of seat belt webbing (14). An energy absorber (32) connected with the belt webbing (14) is actuatable in response to the tensile load on the belt webbing exceeding a predetermined load. The system (10) includes a D-ring (24) having a webbing opening (46) through which the belt webbing (14) extends. The D-ring (24) is supported for movement from a first position to a second position upon actuation of the energy absorber (32). A signalling mechanism (40, 72) is actuatable in response to movement of the D-ring (24) from the first position to the second position for providing a signal perceptible to the vehicle occupant and indicative of actuation of the energy absorber (32). In a preferred embodiment, the signalling mechanism (40, 72) includes an electric switch (40) which is actuated in response to movement of the D-ring (24) from the first position to the second position, and a lamp (72) which is energized in response to the actuation of the electric switch.
