Abstract

An improved spiral coil spring comprising: a plurality of coils ending in two opposite end spores, wherein at least one of said end coils includes at least one offset portion formed with at least two alternate protrusions each of which is located in the same plane as said extreme turn on which said projections are formed, said projections including at least a first projection directed outwards from said spiral coil spring, and a second projection directed inwards in the direction and perpendicular to the main axis of said spring helical spiral, and said protrusions are arranged substantially entirely within said displaced part of said extreme turn, whereby means for surrounding a part of said protrusions on two adjacent overlapping displaced parts having said protrusions to restrict the relative movement of said parts displaced to a maximum angle of deviation are arranged They will flow sensibly within said displaced part.
