Abstract: A chair having an adjustable resilient back recliner mechanism, a pair of adjustable armrests, modular upper back portions and an adjustable lumbar support. The chair includes a tension control that adjusts the tension in the recliner mechanism. The tension control is cam-operated to permit adjustment throughout the entire range of adjustability with only limited rotational movement of a control knob. The chair includes a recline limit control that adjusts the limit of rearward movement in the recliner mechanism. The limit control includes a cable operated stop that interact with a stepped trackway on the seat. The chair further includes a height control for adjusting the seat height including a push-button located in the tension control knob. The armrests include height and angle adjustment mechanisms. The lumbar support includes a lumbar cam that is rotatably mounted to a lumbar pad.

Abstract: A chair control providing both articulating tilt motion and dual-ratio, adjustable, synchronized tilt motion. In a first aspect, the control can be configured as either an articulating tilt control or a synchronized tilt control. In a second aspect, the angle between the seat and the backrest may be selected by the user when the control is configured for either the articulating mode or the synchronized mode. In a third aspect, when in the synchronized mode, the angle between the seat and the backrest increases during forward tilt action to avoid “clam shelling.” In a fourth aspect, a forward tilt selector enables or prohibits forward tilting of the control.

Abstract: A shifter having a base and a shift lever assembly pivotally mounted on the base by a separate pivot member. The pivot member includes a device for keying it to the shift lever assembly and the base includes an opening device configured for receiving the pivot member which includes a radially extending tab at its extreme end. After being inserted in the opening device of the base, the tab prohibits the pivot member from being withdrawn from the base.

Abstract: A shifter for a vehicle includes a base for attachment to the vehicle, and a transmission shift lever having a slidably connectable pivot for pivoting shift lever to the base. The base includes configured sidewalls defining opposing sockets having a first diameter and inlets to the sockets having a first width less than the first diameter. The shift lever includes an integrally molded pivot member with protruding flat-sided rod sections. The rod sections define a second diameter about equal to the first diameter, and the flat sides of the rod sections define a second width about equal to the first width. By positioning the shift lever in an assembly-permitting angular position, the flat sides align with the inlet and the pivot member can be slid through the inlets into releasable pivotal engagement with the sockets.

Abstract: A transmission shifter having a unique structure for pivoting its lever assembly and a novel structure and method for assembling the parts. The structure for pivoting the lever assembly includes caps mounted on the ends of axles extending from the lever assembly. The apparatus and method for assembling the parts includes sockets mounted on a base and on a detent housing, which sockets capture trunnions extending from the lever assembly. Preferably such trunnions are the cap and axle combinations.
