As most of you are now aware, the IIHS has released the findings of their “fit” study on the effectiveness of Belt Positioning Booster (BPB) seats. In this study, they did not actually crash test any of the various boosters seats – they just evaluated how the different boosters positioned the lap/soulder seatbelt on the 6 year old Hybrid III crash test dummy. While I applaud the Institute for taking this initiative it is important that we, as parents, CPS technicians, and advocates learn to assess what constitutes a “good belt fit” and what doesn’t. Memorizing a list of “Best Bets” and “Not Recommended” choices isn’t very helpful overall, although I do think that some of those manufacturers who received several poor ratings for their products might want to seriously reevalute their designs. Honestly, we’ve been saying for years that most combo and 3-in-1 seats do NOT do a very good job of positioning the seatbelt properly when the seat is used in booster mode. Maybe now we’ll finally start to see some improvements in these suboptimal designs. We can hope, right?
