Abstract
A seatbelt energy management device which includes a resistance mechanism coupled to a seatbelt apparatus having a magnetorheological fluid, a permanent magnet having a first magnetic field which orients the magnetorheological fluid to increase the magnetorheological fluid's viscosity, an electromagnet which generates a second magnetic field to cancel the first magnetic field of the permanent magnet to decrease the magnetorheological fluid's viscosity, where the resistance mechanism is controlled by the magnetorheological fluid's viscosity.
