1. An adjustable seat comprising:
- a lower frame comprising a pair of non-parallel support legs, wherein each support leg comprises an upper portion, a lower forward portion, and a lower aft end, wherein each support leg is vertically and longitudinally angled toward a central location so that the distance between the upper portions is less than the distance between the lower forward portions and the distance between the lower forward portions is less than the distance between the lower aft ends;
an upper frame comprising a pair of support arms;
a coupling system comprising an upper rod and a lower rod, wherein the upper rod and the lower rod are pivotally coupled to each of the pair of support arms and the pair of support legs; and
a linear actuator comprising a first end and a second end wherein the first end is coupled to a coupling location on the lower frame and the second end is coupled to a coupling location on the coupling system, wherein the coupling location on the coupling system comprises a cross bar positioned on the upper rod or the lower rod.

Abstract
Described are adjustable seats including an upper frame with a pair of support arms, a lower frame with a pair of support legs, and a coupling system with an upper rod and a lower rod. As examples, the upper rod and the lower rod are pivotally coupled to each of the pair of support arms and the pair of support legs. A linear actuator is coupled to the upper frame, and a track is coupled to the lower frame, wherein the linear actuator is configured to travel along the track. The linear actuator may comprise a first end and a second end, wherein the first end is coupled to a coupling location on the lower frame and the second end is coupled to a coupling location on the coupling system.

9. An adjustable seat comprising:
-
(a) an upper frame comprising a pair of support arms, wherein each support arm comprises an upper portion and an aft end; (b) a lower frame comprising a pair of non-parallel support legs, wherein each support leg comprises an upper portion, a lower forward portion, and a lower aft end, wherein each support leg is vertically and longitudinally angled toward a central location so that the distance between the upper portions is less than the distance between the lower forward portions and the distance between the lower forward portions is less than the distance between the lower aft ends; (c) an upper rod comprising a pair of extensions and a cross beam, wherein each extension is pivotally coupled to the upper portion of each support arm and the cross beam is pivotally coupled to the upper portion of each support leg; and (d) a lower rod comprising a pair of extensions and a cross beam, wherein each extension is pivotally coupled to the aft end of each support arm and the cross beam is pivotally coupled to the aft end of each support leg. - View Dependent Claims (10, 11, 12, 13)
