DEFINITION

Classification: 280/6.154

Terrain slope compensation:

(under subclass 6.15) Subject matter comprising predisposing the load, load carrier, or receptacle portion to accommodate sustained travel upon an expansive inclined surface.

(1) Note. The presence of a gravity induced alteration control is included in this and the indented subclasses.

(2) Note. This and the indented subclasses are intended to

position the load, load carrier, or receptacle portion in an appropriate attitude for prolonged travel upon a hillside or other protracted, nonlevel land configuration. Accordingly, load, load carrier, or receptacle vertical positioning occurring from encountering rough or uneven terrain is not proper for this or the indented subclasses. Such rough or uneven terrain adjustment is a normal function of a suspension system and is provided for earlier in the class schedule if suspension adjustment is caused to occur in response to a force encountered while the vehicle is in surface traversing motion or in an appropriate subclass elsewhere.

SEE OR SEARCH THIS CLASS, SUBCLASS:

5.508+, for an active suspension responding to a force encountered while the vehicle is in surface traversing motion to regulate lateral disposition of the vehicle body, chassis, or frame.

5.514, for an active suspension responding to a force encountered while the vehicle is in surface traversing motion to regulate ground clearance or "trim height".
