Senators raise concerns about car seat collapses.

In continuing coverage, USA Today (5/26, Spangler, 6.31M) reports that Sens. Ed Markey (D-MA) and Richard Blumenthal (D-CT) sent letter to 17 automakers writing, “There has been a long-standing concern that the (standard) ... is not sufficient to mitigate injury or death of a rear-seat occupant due to seat back collapse in a rear-end collision.” Markey and Blumenthal highlighted that children are particularly vulnerable to front seat back failures. The senators also “said the National Highway Traffic and Safety Administration proposed changing the rules for seating system standards in 1974, but it was never finalized.”
