This paper presents injury protection control of the occupant's lower extremities in vehicle collision with an active seat belt and an active knee bolster. The seat belt force for his or her pelvis is controlled by the active seat belt. The contact force between his or her knees and the instrument panel is controlled by the active knee bolster. The control problem is formulated as an optimization problem and the control inputs are calculated to minimize the maximum load of his or her femurs under the constraint of the maximum seat belt force. Numerical simulations show that cooperative control of the active seat belt and the active knee bolster reduces the maximum load of the femurs and the maximum seat belt force at the same time.
