Vehicle seat for reducing the risk of spinal and head injuries of personnel in combat vehicles

Abstract

A vehicle seat for use in military vehicles provides increased protection for a helmeted or unhelmeted combatant soldier. The seat includes a seat portion having a layer of high impact energy absorbing material. A back support portion adjoined to the rear of the seat portion extends upwardly for supporting the rearward side of the seated soldier. The back portion has a lower section for supporting the thorax and lower back, and two overlying sections which are positionable for supporting and restraining rearward movement of the helmeted or unhelmeted head and the neck. The overlying sections are moveable toward and away from the soldier and together define a surface and contour which interacts with the seated soldier during rear end impact to maintain the pre-collision shape of the soldier's supported spinal curves, to aid in avoidance of whiplash and similar injuries. Swivelable side portions actuated by sensors flank the sides of the soldier for further protection.
