Abstract
A series of dummy and cadaver experiments was conducted to establish whether neck and head injuries would be expected with the 30 mil HPR windshield installation were used: no restraint, rubber gasket, and bonded installation using a butyl tape. Head injuries from impacting the cowl were observed with the unrestrained and extruded rubber gasket installations. The accelerations measured on the back of the head in an A-P direction were below the brain damage level as interpreted by the WSU tolerance curve and the Injury Index for the first and second acceleration peaks. No handing or compression injuries to the cervical spine were observed by radiological examination or- palpation.
