ON NOVEMBER 4, 2008 WE WERE IN A FRONT END COLLISION W/A TREE AT ABOUT 40 MPH. MY SON WAS ON THE RIGHT SIDE OF THE VEHICLE IN THE BACK SEAT(WHERE THERE WAS NO IMPACT- I HAVE PHOTOS TO PROVE THERE WAS NO DAMAGE THAT WOULD HAVE CAUSED THE PROBLEM W/THE SEAT). THE SIDE AIR BAGS DEPLOYED, AND STRUCK THE HEAD REST PORTION OF THE EVENFLO BOOSTER SEAT HE WAS SITTING IN. THE HEADREST DID NOT WITHSTAND THE IMPACT OF THE AIRBAG AND WAS JAMMED FORWARD, CAUSING HEAD TRAUMA (BLEEDING AND SWELLING ON HIS BRAIN THAT HAS CAUSED NERVE DAMAGE TO HIS EYES). HE ENDURED A HOSPITAL STAY FROM NOVEMBER 4TH THROUGH NOVEMBER 8TH DUE TO THAT DAMAGE AND STILL HAS PROBLEMS WITH HIS EYES, ALONG W/HEADACHES WHICH WILL REQUIRE MEDICAL FOLLOW UPS & POSSIBLY SURGERY. WE HAVE SINCE REPLACED IT W/A DIFFERENT SEAT. *TR
