Abstract: A seat supporting assembly for use in vehicles such as tractors or the like wherein the seat is surrounded in relatively close relationship by obstructions such as controls which make it difficult for the vehicle operator to get into and out of the seat. The seat supporting assembly provides means for supporting the vehicle seat such that the seat may be moved rearwardly and then rotated to permit access to or egress from the seat. The assembly also provides means which prevent rotation of the seat unless it has been moved to its furthest rearward position. The seat supporting assembly further includes means to facilitate vertical adjustment of the seat and to secure the seat in its desired vertical position.

Abstract: A rugged and long-lasting mounting for a tubular metal leg to the underside of a furniture unit through the intermediary of a sheet metal supporting bracket affixed to the latter, with spaced arms extending downwardly and parallely from the opposite sides of a sheet metal supporting plate on the bracket adapted to abut closely the upper end of said leg. A flange extends inwardly from each of the arms at an acute angle thereto for sliding interengagement with correspondingly cut slots spanning opposed parallel chords on the leg which subtend substantial angles of about 90.degree., to bring the leg and plate into said close abutment while preventing loosening and eventual undesired disengagement therebetween in a direction transverse to said sliding interengagement.

Abstract: An operatory chair, such as a dental chair, having an upper supporting member to which the seat and back unit of an operatory chair may be attached, particularly pertaining to the mechanism by which said supporting member for the seat and back is raised and lowered. The preferred construction comprises a pair of sets of pivotally connected links arranged in lazy tong manner, said links being operated by linkage mechanism actuated by a rotatable screw and follower in such manner that the movement of the supporting member for the seat and back is smooth and relatively slow, particularly at the commencement of elevating movement so as not to include sudden and rapid upward movement as is conventional with typical lazy tong structures used in jacks and the like.

Abstract: A pedestal for a vehicle seat in which a vertically positioned post is mounted on a base and suppports a horizontally rotatable platform pivotally connected to the upper part of the post. A means is provided for locking the seat in an angular position on the vertical axis of the post, and a latch means is preferably provided for centrally locating the seat in its forward position. The locking means includes a handle with a horizontal shaft extending inwardly on the platform for operating a lever to apply pressure to the platform and a plate at the upper end of the post to hold the platform firmly in an angularly adjusted position.

Abstract: A rocker spring unit utilizes separately formed rocker elements and outboard rocker springs. The rocker springs and rocker elements are assembled with two plate members having the rocker springs extended between opposite plate member edges and the rocker elements mounted at inner faces of the plate members inboard of the rocker springs in paired relation to each other and in symmetrical relation to the rocker springs.

Abstract: A swivel base assembly for supporting a device such as a video display terminal (including a video monitor and a keyboard) and including means for rotating the device through a large angle, for example, 270.degree.. The swivel base assembly includes a tray on which the device is positioned and a circular base member having a space for containing a circularly- wound data-carrying cable, such as a coaxial cable, for use by the device on the tray. The base member also includes a pair of upstanding spaced stop members formed therein and arranged to cooperate with a depressed stop member formed in the tray to establish the aforementioned 270.degree. range of angular rotation.

Abstract: A seat adjuster mechanism for a bench-type vehicle seat includes a first adjuster track assembly mounting the driver's end of the vehicle seat to the vehicle and a second adjuster track assembly mounting the passenger's end. The track assemblies are curved about an axis extending transversely of the vehicle so that the pitch and elevation of the vehicle seat are changed as the seat is adjusted fore and aft. First and second swivel mechanisms connect the respective adjuster track assemblies to the vehicle seat. First and second lock pawls are associated respectively with the first and second adjuster track assemblies for selective engagement in notches in a notched lock bar to latch the seat in desired position. A latch operating device is provided which is actuable in one direction to unlatch both the first and second latch means to permit simultaneous bodily fore and aft adjusting movement of the seat on the first and second adjuster track assemblies.
