Abstract
An adaptive energy absorption system for a vehicle seat that functions in dual-modes, including a primary mode during severe (shock event) operation and a secondary mode during normal (non-shock event) operation. When operating in primary mode, the present system automatically adjusts a VPEA in real-time to keep loads transmitted to the occupant's body below acceptable injury threshold levels, and can recover to perform said function for multiple shock events. When operating in secondary mode the system reduces vehicle vibration transmitted to the occupant, thereby reducing fatigue and increasing situational awareness.
