    Abstract: An improved system for passenger safety in a front-end vehicle collision, whereby the kinetic energy of a passenger may be reduced before the passenger is exposed to the crash deceleration. An electrical sensor mounted at the extreme front end of the vehicle senses the onset of a front-end collision and sends a crash signal to the passenger compartment. Preferably, the sensor is a normally-closed momentum-activatable switch. A passenger seat is mounted on translating means permitting rearward motion and has a harness to secure a passenger to the seat. The seat is held in place by a shearable pin. Beneath the seat, attached between the floor of the vehicle and the frame of the seat, is a linear actuator powered by an explosive charge which is ignitable electrically in response to the crash signal. Upon firing of the actuator, a guillotine edge on the seat frame shears the pin, and the seat and passenger are thrust rapidly rearward so that the passenger is travelling rearward with respect to the vehicle and more slowly forward with respect to the ground. Thus, the kinetic energy of the passenger is reduced and the intensity of his deceleration from the crash pulse is minimized. The seat back and cushion may be hinged for rotation backwards on the seat frame. A second explosive actuator causes rotation about the hinge coincident with the rearward translation of the frame. Rotation of the seat can orient the passenger more favorably to withstand the remaining shock of the crash pulse.

    Abstract: An improved system for passenger safety in a front-end vehicle collision, whereby the kinetic energy of a passenger may be reduced before the passenger is exposed to the crash deceleration. An array of variably momentum-responsive electrical sensors mounted in the forward portion of the vehicle senses the onset of a front-end collision and sends one or more crash signals to the passenger compartment. A passenger seat is mounted on translating means permitting rearward motion and has a harness to secure a passenger to the seat. Beneath the seat, attached between the floor of the vehicle and the frame of the seat, is an array of pairs of linear actuators, each actuator being powered by an explosive charge and each pair being electrically connected uniquely to one of the momentum sensors. Upon firing of one or more of the actuator pairs, the seat and its passenger are thrust rapidly rearward so that the passenger is travelling rearward with respect to the vehicle and more slowly forward with respect to the ground, the number of pairs fired after collision of the vehicle being proportional to the forward velocity of the vehicle at the time of the collision. Thus, the kinetic energy of the passenger is proportionally reduced and the intensity of his deceleration from the crash pulse is proportionally minimized.
