ABSTRACT:
A vehicle seat having a seat base frame (10) mounted on cross rails (12) is provided with a height adjustment mechanism comprising a pair of generally U-shaped leaf springs (14) which constitute the sole support for the seat on the crossrails (12). The leaf springs each have a pair of oppositely inclined upstanding tongues (18) connected to the seat base frame through pin and slot connections (32, 34) and, adjacent their upper ends, each pair of tongues (18) is connected by a rod (37) which serves both to stiffen the tongues (18) and also to effect adjustment of their inclination so as to vary the height of the seat base (10) above the rails (12).
