DEFINITION

Classification: 248/570

Forming unitary structure with relative movement between parts:

(under subclass 568) Structure wherein the additional energy absorbing element comprises a plurality of discrete members held together in such a manner as to allow relative movement with frictional contact between such members.

(1) Note. Such elements may be an assemblage of fibrous or particulate elements held together for relative movement therebetween or a spring member made up of relatively movable components in frictional contact.
