Too strong inclination of a seatback leads to the fact that the humeral section of a seat belt will not nestle on a thorax that in an essential measure reduces efficiency of its protective functions. The more the seatback is inclined back, the probability of slipping of the body sitting under zone section at strong front blow is higher and the heavier can be traumatized. Instructions for adjustment of seatbacks are provided in the Section Adjustment of Seats.
