Abstract
A seat support assembly has a lower member with a first channel extending in a front-back direction of the seat support assembly and an upper member positioned above the lower member and having a second channel extending in the front-back direction. A first linkage has a lower end pivotably coupled to the lower member and translatable in the front-back direction by way of the first channel and an upper end pivotably coupled to the upper member. A second linkage has a lower end pivotably coupled to the lower member and an upper end pivotably coupled to the upper member and translatable in the front-back direction by way of the second channel. The first and second channels are offset from one another in the front-back direction.
