Abstract
A seat spring for a seating structure having front and rear frame rails wherein the spring is constructed from a one piece wire body shaped to form a front end fishmouth portion mounted on the front rail, a yieldable rear end portion mounted on the rear frame rail and a variable length main portion extending between the front and rear portions. The fishmouth portion and the front end of the main portion are configured so that when the spring is deflected in response to a downwardly directed seating load, the spring will bottom out on the front frame rail without any wire-to-wire engagement of portions of the spring during deflection. The result is a limited deflection spring which, under shock load, will deflect without any noise.
