ABSTRACT:
In a seat suspension wherein a seat part is slidable fore-and-aft on a suspension part, a latching member having an elongated slot therein is swingable to and from a normal position about a rivet secured to the seat part and extending through the slot. In its normal position, the latching member engages the suspension part to be locked against fore-and-aft motion, but the seat part can move fore-and-aft between slot-defined limits. A control member is pivoted to the latching member on an axis spaced from and parallel to that of said rivet, which extends through a triangular cutout in the control member. The control member has one limit position wherein a portion of said cutout registers with said slot for fore-and-aft shock isolating motion of the seat part and an intermediate position wherein an apex portion of the cutout engages the rivet to prevent seat part motion. Swinging the control member to an opposite limit position swings the latching member out of normal position for fore-and-aft seat part adjustment. One tension spring urges the seat part forwardly and biases the latching member to normal position, another tension spring urges the seat part rearwardly and biases the control member for toggle motion between its intermediate and opposite limit positions.
