ABSTRACT:
This invention relates to supports, for vehicle seats, having a generally upright configuration. Provision of a plurality of seat adjustments, for operator comfort and safety, performable with an economy of movement and structure which tends to maximize free, usable space within a vehicle cab, is achieved by the invention. A housing member (13) has facing traces (17), and a carriage member (14) bears the seat and a plurality of rollers (51, 53) which engage the traces (17). A bracket assembly (15), disposed between housing and carriage members (13, 14), is selectively slidable with respect to the carriage member (14) to effect height adjustment and, when locked with respect to the carriage member (14), is operable upon to effect weight adjustment.
