A transmission shifter includes a shift lever, and a knob with attachment clip that mechanically locks the knob atop the lever with a single assembly motion. The clip is located inside a hole in the select knob, and the lever includes a notch near its top. The clip is positioned to flex to facilitate assembly as the lever is inserted into the hole, but then unflex to engage the notch and lock the knob to the lever. To remove the knob from the lever, a removal tool is used to depress the clip, pushing it out of the way and allowing the select knob to be pulled off the lever. The illustrated shifters include a mechanically-actuated pawl actuator system and an electrically-actuated pawl actuator system.

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 &ldquo;clam shelling.&rdquo; In a fourth aspect, a forward tilt selector enables or prohibits forward tilting of the control.
