“…For both parametric sensitivity analyses, H-pt vertical excursion was also characterized with the use of the following methods: (1) percent difference between preand posttest and (2) peak H-pt vertical excursion/H-pt vertical excursion limit recommended by Viano and Arepally [3]. The first method assesses compliance with the …”

“…Viano and Arepally suggest a submarining criterion limiting the hip joint or hip-point (H-pt) vertical excursion to be not more than 1.97 in. [3,7]. Adomeit and Heger further recommend that the main requirement for avoiding submarining is to limit the vertical downward motion of H-pt [2].…”

“…Submarining can potentially lead to severe internal injuries of organs in the abdominal region [6]. Previous motor vehicle research has shown that motion sequence of the pelvis and upper torso during a crash can be correlated with the risk of submarining [2,3]. Accordingly, kinematic analysis techniques have been used to compare and optimize automotive seating system designs.…”

“…Occupant lap belt fit and anchorage location, seat design characteristics, and seated posture can all affect submarining risk [2][3][4][5][6]. Submarining is characterized by the pelvic restraint slipping upward over the iliac crests and loading the soft abdominal tissues.…”

Abstract-Many wheelchair users must travel in motor vehicles while seated in their wheelchairs. The safety features of seat assemblies are key to motor vehicle occupant crash protection. Seating system properties such as strength, stiffness, and energy absorbance have been shown to have significant influence on risk of submarining. This study investigated the effects of wheelchair seat stiffness and energy absorption properties on occupant risk of submarining during a frontal motor vehicle 20 g/30 mph impact using a validated computer crash simulation model. The results indicate that wheelchair-seating stiffness and energy absorption characteristics influence occupant kinematics associated with the risk of submarining. Softer seat surfaces and relatively high energy absorption/permanent deformation were found to produce pelvis excursion trajectories associated with increased submarining risk. Findings also suggest that the current American National Standards Institute/Rehabilitation Engineering and Assistive Technology Society of North America (ANSI/RESNA) WC-19 seating integrity may not adequately assess submarining risk.

“…The chest acceleration calculated in a 3 ms interval and the chest maximum deflection are employed to reflect the injury response of the dummy chest. Viano, etc studied the probabilities of getting injured on different body parts in traffic accidents and proposed the weighted injury criteria (WIC) [10] . WIC takes into consideration the injury values of head, chest, neck and femur, and the largest weight 0.53 is given to the head injury value in the WIC calculation formulas.…”

Abstract. To verify that a forward displaced position has effects on the driver injury levels in front-end collisions and estimate the injury levels in real accidents under this situation, a series of sled tests were conducted with dummy in different forward displaced positions. Injury response values of different body regions were calculated and used to estimate the distribution of injury levels in real accidents. The results of sled tests showed that injuries response values of the dummy driver increased obviously as its body leaned forward. And the estimated distribution of injury levels had a good similarity with statistics results. This method could also be employed to have a more comprehensive estimation of automotive active safety on occupant protection.
