Abstract
A compression spring useful in vehicle suspension applications has an extended plateau region in its force/deflection characteristics, such extended plateau being obtained by virtue of the formation of the spring as a tubular elastomer body of progressively increasing cross-section from one end to the other provided with longitudinally spaced-apart reinforcements defining bulging instability sites therebetween. The spring when under compression undergoes bulging sequentially at these sites.
