Abstract
A seat suspension device including an elastic biasing mechanism for elastically biasing a seat frame away from a lower base frame, a locking mechanism for locking the seat frame to thereby place the seat suspension device in a locked state, and a biasing force adjustment mechanism for adjusting the biasing force of the elastic biasing mechanism. The locking mechanism is so arranged that it will bring to a locked state the seat suspension device when the biasing force of the elastic biasing mechanism is reduced to a lowest degree by operation of the biasing force adjustment mechanism. Accordingly, by merely operating the biasing force adjustment mechanism, both biasing force adjustment and locking/unlocking operation are effected.
