The Knoedler Air-Chief seat is a sophisticated seating solution designed for comfort and adjustability, particularly suited for heavy-duty vehicle applications. It incorporates a range of features aimed at enhancing driver comfort, reducing fatigue, and providing a customizable seating experience.

Function Description:

The Air-Chief seat is an air-suspension seat that utilizes an air control valve to adjust the suspension's pressure, allowing the user to customize the ride height and firmness. This air suspension system, often combined with an isolator, helps to absorb road vibrations and shocks, providing a smoother ride. The seat offers extensive adjustability for various body types and preferences, including fore and aft movement, backrest recline, cushion extension, and armrest positioning. An isolator lockout control allows the user to stabilize the seat when desired, preventing unwanted movement. The seat is also designed with safety in mind, featuring an ICP (Integrated Control Panel) for seatbelt connection and a warning regarding adequate head clearance.

Usage Features:

The Air-Chief seat offers a comprehensive set of user-friendly adjustments:

Front Adjustable Armrests: A knob allows rotation to set the arm resting point, providing support and comfort for the arms.
Backrest Adjuster: A lever is lifted to release the backrest, allowing the user to recline and find a comfortable position.
ICP (Integrated Control Panel): This feature is used to install a tether-belt system directly to the truck floor, enhancing safety.
Valve Controls: These controls manage the air suspension. Pressing and holding "+" increases pressure (and thus height/firmness), while pressing and holding "-" decreases pressure.
Isolator Lockout Control: Pushing left locks the isolator, stabilizing the seat, while pushing right unlocks it, allowing the isolator to function. It's important to note that the isolator does not work if there is no air in the suspension system.
Cushion Extension and Angle Adjustment: The cushion can be lifted up and pulled out to adjust in three positions for thigh support. To shorten the cushion, lift up and push it in.
Seat Fore and Aft Adjustment: A lever on the left side is pulled to unlock the seat, allowing it to slide to the desired position. Users must ensure the seat is locked into position after adjusting for safety.
Bolster Adjustment System: This system allows for fine-tuning of the seat's side bolsters for improved lateral support.
Height Adjustment: Controlled via the air suspension valve controls.
Slide Adjustment: Allows the entire seat assembly to move forward and backward.
8-Way Power Switch (Power Chief Only): This advanced switch provides granular control over various seat functions:
- Recliner adjustment for backrest angle.
- Front seat cushion tilt up or down.
- Seat fore-aft position.
- Rear seat cushion tilt up or down.
