TEXT:

Per conversations with Mike Pine and Jim Gilkey at NHTSA, I am sending to you samples of three of our base car seats. The samples have the head impact protection foam attached with two push in pins (Christmas tree). We presently, and have always in the past, glue the head impact foam to the head area of the car seat shell. We would like to make this change to better secure the foam to the car seat shell and help our manufacturing process. Please evaluate these three samples (Models 4560, 4590 and Century STE series) for head impact protection (MVSS No. 213, S5.2.3) and protrusion limitation (MVSS No. 213, S5.2.4) and respond in writing to Century Products Company. Please advise as to compression deflection and head contact safety. Century Products feels the change will not diminish or change the head impact protection of the slow recovery energy absorbing foam.
