Manage energy transferred at contactAccelerate occupant and soften impactImplement energy absorbing devicesPress on seat at the earliest stage possibleProvide best contact between occupant and seatProvide stiff coupling of seat and floor Provide lateral stiffness of seat
Limit intrusion of hitting structure (no squeeze)Limit relative movement of door
Stiffen up door itselfImprove stiffness of pillars and rockers
