Knob control for slim vent in vehicle

A vent assembly of a vehicle comprising:

• a bezel defining a vent opening through which an airflow is directed;
• a primary vane extending across the vent opening, the primary vane selectably movable about a primary vane axis to adjust a direction of the airflow in a first direction;
• a plurality of secondary vanes arrayed across the vent opening, each secondary vane selectably movable about a secondary vane axis nonparallel to the primary vane axis to adjust the direction of the airflow in a second direction;
• and
• an adjustment knob having a knob central axis, the adjustment knob configured such that movement of the adjustment knob along the knob central axis moves the primary vane about the primary vane axis, and rotating the adjustment knob about the knob central axis moves the plurality of secondary vanes about their respective secondary vane axes;
• an adjustment shaft extending from the adjustment knob along the knob central axis;
• two parallel disks located along the adjustment shaft spaced apart defining a disk gap therebetween;
• and
• a vane pin extending from the primary vane and disposed in the disk gap;
• wherein movement of the adjustment knob along the knob central axis moves the two parallel disks along the central axis, thereby moving the vane pin about the primary vane axis and the primary vane about the primary vane axis.
