Abstract
A power seat adjustment assembly comprising an active material actuator, adapted for use when a resting load is present within the seat, and configured to reduce actuator demand, and therefore actuator size and/or rating, by modifying the load to augment performance.
Claims20
A power adjusted seat assembly composing a seat, and adapted for use when a resting load is present within the seat, said assembly comprising:
- at least one reconfigurable seat structure shiftable between first and second permanent dimensions, orientations, positions, or conditions;
- an active material actuator drivenly coupled to the structure;
- and
- a mechanical transmission drivenly coupled to the structure, so as to act in concert with the actuator, and configured to receive and modify at least a portion of the load,
- said actuator and transmission being cooperatively configured to cause the structure to shift between the first and second permanent dimensions, orientations, positions, or conditions, when the resting load is present and the actuator is activated.
