# Assessment of Nanobag as a New Safety System in the Frontal Sled Test
## 3 Results and Discussion
### 50 km/h Results
The maximum value of the HIC is 702 (M, P95, 54 YO, 184 cm, 96 kg; 10 layers nanobag); its minimum is 377 (M, P05, 54 YO, 154 cm, 55 kg, nanobag 4) and the average value is 454 (safety value of HIC). The maximal probability of AIS 2+ for head and neck are 35.5% and 19%, respectively. These results suggest the safety region of injury risk for all safety features. The results also indicate a significant increase of head injury risk with a higher impact velocity (AIS2+ for head: 6.73% and 35.5% for 30 km/h and 50 km/h pulse, respective), while the neck injury risk increases in-significantly (AIS2+ for neck: 14.66% and 17.7% for 30 km/h and 50 km/h pulse, respective). The BrIC criterium results with the minimum value 0.5 (F P05, 64 YO, 154 cm, 60 kg--airbag) and with the maximum 1.09 (M P50, 64 YO, 180 cm, 95 kg--airbag). Generally, the BrIC gives similar values for each particular anthropometry in all configurations. Criterion UBrIC has its minimum MPS value at 0.17 (F P05, 14 YO, 153 cm, 41 kg--nanobag 10 layers; F P05, 64 YO, 154 cm, 60 kg--airbag) and the minimum CSDM value of 0.24 (F P05, 64 YO, 154 cm, 60 kg--airbag), while the maximum MPS value is 0.4 (M P50, 64 YO, 172 cm, 83 kg--airbag) and the maximum in CSDM is 0.55 (M P50, 64 YO, 172 cm, 83 kg--airbag). The UBrIC criterion results in very similar values for the specific anthropometry; however, the maximal values for MPS and CSDM are predicted for the airbag. The minimum contact force is 0.12 kN (M P50, 28 YO, 178 cm, 76 kg--airbag) and maximum value 3.69 kN (M P95, 64 YO, 180 cm, 95 kg--airbag). The minimum value is predicted for the average male (the size of P50 dummy) with the airbag SRS. Such results confirmed that the passive safety measures (seat belts and airbag) are optimized for this anthropometry. Similarly, to the 30 km/h pulse, the results of the crash scenario with no safety features (seat belts only) for the average occupant (M, P50, 28 YO, 178 cm, 76 kg) are also provided. Table 5 summarizes the minimum, maximum and average values for all particular criteria, together with the anthropometry and SRS. The results of 50 km/h impacting velocities also predicted the assessment of the nanobag with the safety region of the head and neck injury risk. Moreover, it also gave similar safety measures to the nanobag and airbag in this specific crash configuration. Most of the extremes values were also predicted for the airbag (maximum and minimum) in the higher velocity impact. \begin{table}
