The U.S. National Highway Traffic Safety Administration (NHTSA) has issued a notice of proposed rulemaking (NPR) to amend Federal Motor Vehicle Safety Standard (FMVSS) No. 213, “Child restraint systems,” to adopt side-impact performance requirements for all child restraint systems designed to seat children up to 40 pounds. With an aim to ensure that child restraint systems “provide a minimum  level of protection in side impacts by effectively restraining the child, preventing harmful head contact with an intruding vehicle door or child restraint structure,  and by attenuating crash forces to the child’s head and chest,” the agency also hopes to fulfill the statutory requirement of the “Moving Ahead for Progress in the 21st Century Act” of July 6, 2012, requiring that NHTSA issue new rules to protect children during side-impact crashes. Comments will be accepted until April 28, 2014. See Federal Register, January 28, 2014.
