lap belt

"The child's mother also said the lap belt on the chair was much too tight," the ombudsman's report said.

For a vehicle to earn a "good" rating, the crash test dummy should not record excessive risk of injury to the body parts and should remain correctly positioned during the crash without sliding forward beneath the lap belt.

The lap belt is designed to hold the body in the seat.

In addition to a lap belt and upper body restraint installed by the helicopter manufacturer, FlyNYON provided passengers on the doomed flight with a nylon fall-protection harness that could be released only by cutting a tether with a provided knife or unscrewing a locking carabiner at their backs, investigators said.

Crew members went row by row to check on passengers and a flight attendant described reaching Row 14 to find a woman still restrained in her seat by her lap belt, but whose upper torso, arms and head had been pulled outside the plane through a broken window.
