A system for generating haptic effects in a vehicle, wherein the vehicle comprises a seat and a seat belt, is provided. The system comprises one or more haptic output devices positioned at or attached to the seat belt. The system further comprises a processor configured to receive a sensor signal from a sensor that is configured to sense information associated with the vehicle's environment or the vehicle's condition. The system is further configured to determine whether to generate a haptic effect based on the sensor signal, and to output a haptic control signal and communicate the haptic control signal to the one or more haptic output devices in response to a determination to generate the haptic effect. The one or more haptic output devices are configured to generate the haptic effect based on the haptic control signal.
