| Outline of Final Research Achievements |
To determine likely neck injuries of a short height of pregnant women sitting in the rear seat, sled tests with full frontal impact at target velocities of 29 km/h and 48 km/h using a shorter-height pregnant woman crash test dummy were performed.
During frontal collision tests, the shoulder belt compressed the neck at a pressure >12.8 MPa, even during the low-velocity impact. In addition to neck flexion, right side bending and the head and chest moving in opposite directions were observed. The direct force may cause serious injuries to major vessels and nerves and the complex combination of head and neck movements may cause neck sprain. Healthcare professionals should consider providing advice to pregnant women of a shorter height about the correct seat belt path and the use of booster seats, if required. Improvements to seat belt systems for rear seats are required for passenger safety, especially for pregnant women.
