Abstract

An adjustable planar sled or support base for a seat assembly which can be selectively adjusted in its length for changing the distance between the seat assembly and a fixed station such as a machine or the like. The planar sled or support base comprises a base plate including a recessed bed opening toward the front end of the support base and an adjustment plate member slidably engaged within the recessed bed and having an end extending outwardly therefrom. The adjustment plate member has a connecting device at the outwardly extending end for anchoring the seat relative to the machine. The adjustment plate member is movable in the bed for adjusting the length of the support base. The base plate includes fasteners to releasably secure the adjustment plate member in the recessed bed to maintain the selected length of the support base.
