Children and Restraints - Seat Belts and Shoulder Harnesses:

Injuries that arise from the vehicle's restraint system are dependent on the velocities, speeds, involved in the collision. They can vary in type from internal injuries caused by the lap belt to fractures of the clavicle from the shoulder harness, to back and neck injuries caused by the anchoring mechanism of the restraint. More common and less severe are bruises, abrasions and, for females, chest injuries.

Injuries to children from seat belts and shoulder harnesses can be as severe as to adults. This is primarily due to the fact that these restraints are designed to fit adults and improperly hold children.
