Airplane Seats Might Not Be Strong Enough For Overweight Passengers, Scientists Say

More than six decades ago, when the federal standards on the strength of airplane seats and seat belts were written, government regulations specified that seats be designed for a passenger weight of 170 pounds. But now the average American man weighs nearly 194 pounds and the average woman 165.

Now, some engineers and scientists have raised questions about whether airplane seats, tested with crash dummies that reflect the 170-pound rule, are strong enough to protect heavy travelers.

"If a heavier person completely fills a seat, the seat is not likely to behave as intended during a crash," said Robert Salzar, the principal scientist at the Center for Applied Biomechanics at the University of Virginia. "The energy absorption that is built into the aircraft seat is likely to be overwhelmed and the occupants will not be protected optimally."
