Child car seats would for the first time have to protect children from death and injury in side-impact crashes under regulations the government proposed Wednesday.
The proposal by the National Highway Traffic Safety Administration would upgrade standards for child seats for children weighing up to 40 pounds to include a new test that simulates a side crash. The agency estimates the standards will prevent the deaths of about five children and injuries to 64 others each year.
"Car seats are an essential tool for keeping young children safe in vehicles, and they have a proven track record of saving lives," NHTSA Acting Administrator David Friedman told a gathering of automotive engineers.
Under the proposal, the new tests would simulate a "T-bone" crash, in which the front of a vehicle traveling 30 mph strikes the side of a small passenger vehicle traveling at 15 mph. NHTSA's research has shown "these speeds will cover over 90% of the side-impact crashes seen in the real world," Friedman said.
The tests would position the car seat on a sled, with another sled ramming the side of the sled with the seat, rather than using actual vehicles since the aim isn't to test the crash worthiness of specific vehicles, NHTSA officials said.
Research shows that many child deaths and injuries in side-impact crashes involve a car carrying children that is stopped at an intersection, usually at a light or stop sign, officials said. When the car begins to accelerate to go through the intersection, it is struck in the side by a vehicle traveling at a higher rate of speed on the cross street.
The side-impact test — the first of its kind — would simulate the acceleration of the struck vehicle and the vehicle's door crushing inward toward the car seat. Besides using a 12-month-old child dummy already approved under NHTSA standards, the proposed test would also use a to-be-developed side-impact dummy representing a 3-year-old child.
"As a father of two, I know the peace of mind this proposed test will give parents," Transportation Secretary Anthony Foxx said in a statement. The test "will give parents and car-seat makers important new data on how car seats perform in side crashes."
Safety advocates were overjoyed.
"I think this is terrific," said Joan Claybrook, who was the NHTSA administrator during the Carter administration and later president of Public Citizen. She noted that today's passenger vehicles have eight air bags, in part to protect adults from side-impact crashes. "We have an absolute moral obligation to protect children as well," she said.
Some manufacturers are already taking steps to improve the protection afforded by their car seats in side-impact crashes. The Dorel Juvenile Group, the world's largest car-seat maker, has been incorporating small, already-inflated air bags into some of their models to protect children's heads from injury in side-impact crashes since 2009, said Julie Vallese, a spokeswoman for the Columbus, Ind., company. Another impact-absorbing technology derived from protections found in Indy race cars is built into the sides of the chairs, she said.
The public will have 90 days to comment on the proposed regulations after they are published this week. The regulations wouldn't be made final until after the agency has reviewed the comments and answered any important issues that may be raised. That typically takes months and sometimes years, although NHTSA officials said they hope to move quickly.
