DEFINITION

Classification: 280/124.174

Plural cooperating leaf springs (e.g., full elliptical spring, helper springs):

(under subclass 124.17) Subject matter including multiple leaf springs associated and acting together within a common support region of the vehicle body, chassis, or frame.

(1) Note. A single leaf spring constructed of plural flexible strips is not considered proper for this subclass.

(2) Note. A symmetrical arrangement, providing mere duplication of a leaf spring suspension upon each lateral side of the vehicle body, chassis, or frame, is not to be considered plural cooperating leaf springs located within a common support region of the vehicle body, chassis, or frame and is not proper for classification in this subclass.
