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.

What is claimed is: 1. An adaptive load-limiting seat belt buckle presenter for the restraint of an occupant in a vehicle comprising:a support tube fixed on the vehicle;a plow assembly movable within the tube and connected to the buckle so that movement of the plow assembly will present the buckle at a selected position relative the occupant;said plow assembly having a plurality of plow elements selectively engageable with the tube to plow troughs in the tube when the onset of an occupant restraining load on the buckle causes movement of the plow assembly within the tube;and said plow assembly having a plow actuator mechanism by which a selected number of the plurality of plow elements are selectively engageable or not engageable with the tube upon the onset of occupant restraining load to thereby adapt the presenter to sensed conditions of vehicle and occupant usage.
