The buckle portion of the safety belt system is different depending on the seat option chosen.
The National Standard and Comfort seat has a separate buckle that is attached to a floor
anchor by a seat strap. This seat strap is not adjustable, and does not need to be adjusted.
Comfort Clip Operation
When provided, the comfort clip is located on the shoulder strap just below the D-ring.
When adjusting the comfort clip, the following procedure must be followed for proper
adjustment:
1 Pull out only enough webbing to allow slight pressure to the shoulder and chest. Allow
no more than a 25 mm (1 inch) slack when measured between the chest and the belt.
2 To activate the clip mechanism feature, lift the lever up to clamp the webbing in place.
Note: When the safety belt is not in use, the clip should be in the open position to allow the
seat belt to retract to its proper position. Also make sure that the adjustment of the comfort
clip does not interfere with the operation of the safety belt.
