Abstract
A seat suspension device for use in an automotive seat which comprises a pair of right and left X-shaped links for connecting a lower frame with an upper frame and a torsion bar journaled to the pivotally-connected portions of the two X-shaped links. The torsion bar includes two ends, with one end thereof being engaged with one of the X-shaped links and the other end engaged with the other X-shaped link, so that the upper frame can be supported resiliently relative to the lower frame.
