A fold-down automotive seat with spiral spring element for biasing a seat back thereof towards a seat cushion thereof is of such a structure wherein a first engagement element is fixedly disposed on the seat back side, whereas a second engagement element fixed to a base plate on the seat cushion side. The second engagement element is situated at a predetermined point forwardly of and distant from the first engagement element. One movable end of the spring element is normally engaged with the first engagement element. Upon folding down the seat back, such movable end of spiral spring element is engaged with the second engagement element, which blocks application of biasing force of the spring element to the seat back, whereupon the seat back is temporarily stopped at the afore-said predetermined point and prevented from being abruptly folded down onto the seat cushion.
