What is submarining in the context of car accidents?

Critical vertical kinematic of the pelvis relative to the lap belt, causing a high loading of the abdomen Signup and view all the answers

How does the ossification of the skeleton in children relate to the risk of injury in car accidents?

The iliac crest of children is not yet ossified but deformable and soft, which can cause severe injuries if the lap belt intrudes in the abdomen during an accident. Booster seats and child seats can guide the belt on top of the leg and prevent submarining. Signup and view all the answers

What is the danger associated with using cheap booster seats for children without belt guides?

Serious injury risk, especially due to submarining, as the lap belt may intrude in the abdomen and cause severe injuries. Signup and view all the answers

How does the pelvis contribute to the correct routing of the lap belt in car accidents?
