High acceleration protective seat

摘要

A G-protective seat is disclosed for disposing an occupant within a vehicle in a supine tucked posture during high acceleration loading substantially along the Z-axis of the vehicle. At the onset of high Z-axis acceleration, a pair of pivotal leg support members are actuated to fold the legs of the occupant upwardly thereby drawing the knees up to the chest of the occupant in an intermediate tucked position. With the occupant in the tucked position, the seat rotates upward about an axis substantially defined by the occupant's eyes into a supine position for the duration of the high acceleration loading.
