ABSTRACT:
An adaptive load-limiting seat belt buckle presenter includes a plow assembly movable within a tube and connected to the buckle by cables. Movement of the plow assembly presents the buckle at various positions relative to the occupant. The plow assembly has a plurality of plow elements that engage with the tube to plow troughs in the tube when an occupant restraining load moves the plow assembly within the tube. A plow actuator mechanism selects a number of the plurality of plow elements to be engaged or not engaged with the tube to thereby adapt the load-limiting capability of the presenter. A controller and various sensors cooperate to operate an adjusting motor for translating the plow assembly within the tube to present the buckle at a desired position and to also operate a rotary actuator to select the number of plow elements that will be engaged or not engaged.
