Claim:
1. A car seat for protecting vertebral column, comprising: a backrest and a seat, the backrest and the seat having a first surface and a second surface; the backrest and the seat comprising at least a cushioning material, fixated on a car; the cushioning material comprising a foam; the backrest and a seat comprising a portion near a center of cushioning material that corresponds to a human vertebral column is disposed with a troughed recess, where the width of the troughed recess is larger than the width of the vertebral column, and the location of the troughed recess on the backrest traverses along the shape of the vertebral column to extend downward to the seat; and a plurality of viscous elastomers, wherein the plurality of viscous elastomers having a first viscous elastomer, a second viscous elastomer, a third viscous elastomer and a fourth viscous elastomer, wherein the first viscous elastomer and the second viscous elastomer are disposed on the backrest, wherein the first viscous elastomer is disposed on a first side of the troughed recess and the second viscous elastomer is disposed on a second side of the troughed recess, wherein the third viscous elastomer and the fourth viscous elastomer are disposed on the seat, wherein the third viscous elastomer is disposed on the first side of the troughed recess and the fourth viscous elastomer is disposed on the second side of the troughed recess, wherein each of the first viscous elastomer, the second viscous elastomer, the third viscous elastomer and the fourth viscous elastomer having a rectangular shape, wherein each of the first viscous elastomer, the second viscous elastomer, the third viscous elastomer and the fourth viscous elastomer having a longitudinal axis parallel to a longitudinal axis of the troughed recess, wherein the first viscous elastomer and the second viscous elastomer both having a length greater than half of a length of the backrest.
