Abstract: An apparatus (10) comprises seat belt webbing (24). An elongated member (30) is connected with the seat belt webbing (24). Tension in the seat belt webbing (24) is transmitted to the elongated member (30). An arm (106) is associated with the elongated member (30). The arm (106) receives a force from the elongated member (30) when tension in the seat belt webbing (24) increases. The force acts on the arm (106) through a moment arm creating a torsion force on the arm (106). At least a portion of the arm (106) moves in response to the torsion force. A device (102) is responsive to movement of the at least a portion of the arm (106) due to the torsion force to provide an output signal indicative of the tension in the seat belt webbing (24).
