HIC uses the time and acceleration rate of a human head prior to impacting an object (like a seat back) to generate an injury risk value.Ī 1988 FAA regulation requires that airline passenger seats have an accident HIC value under 1000. HIC values above 1000 are considered life threatening. HIC is now used in many industries, including sports equipment, playground design, and airplanes.

Neither seats, Vinyl or Leather are waterproof. Neither Leather or Vinyl breathes except through the stitching. Most people cannot visually tell the difference between our premium marine grade Vinyl and Leather unless they are side by side and then it needs to be pointed out which is which.
