Seatbelt submarining injury and its prevention countermeasures: How a cantilever seat pan structure exacerbate submarining

Seatbelt submarining occurs during a frontal motor vehicle crash when the load transfers to a soft anatomical region such as a the abdomen or chest wall. It is dependent on the design features of the seat pan and the seatbelt system, and a lack of anti-submarining features can result in critical injuries to vehicle occupants. This article presents a case report that demonstrates seatbelt webbing injury to due seatbelt submarining during a frontal crash. The subject was a 61-year old male who sustained critical abdominal and thorax injuries in the crash. The crash analysis shows inadequate design of the cantilever seat pan anti-submarining feature as well as a lack of a seatbelt load-limiter and pretensioner. These factors contribute to a lack of occupant protection by the seatbelt system, resulting in severe occupant injuries.
