The program objective was to develop an effective inflatable occupant restraint system for unbelted rear seat occupants of standard-size motor vehicles. An extensive series of developmental and evaluation impact sled tests included variations in occupant position and size. The restraint system includes a crushable honeycomb knee bar to limit femur loads and to control the head and upper torso trajectory of the unbelted occupants. Non-deployed protection is provided for crash speed pulses up to approximately 20 mph in order to satisfy multiple impact considerations, and non-vented side bags are used for oblique impact protection. In terms of present injury criteria, the restraint was effective for the 50th percentile adult for crash speeds up to 45 mph (barrier equivalent) for frontal and 30 deg oblique sled simulated barrier crashes. A performance envelope of crash speed at which protection is provided for other dummy sizes and positions was obtained. (Author)
