Bump stopper for suspension system

A bump stopper for a suspension system that has a parting line along a longitudinal direction of the bumper stopper and upper and lower convex portions coaxially connected each other and contacting each other in a compressed state, the bump stopper comprising:

• first upper and lower reinforcing blocks integrally formed along the parting line respectively on the upper and lower convex portions, having a constant width along a circumferential direction of the bumper stopper, and forming a first contact angle therebetween in the longitudinal direction of the bumper stopper;
• and
• second upper and lower reinforcing blocks integrally formed respectively on the upper and lower convex portions, having a constant width along the circumferential direction of the bumper stopper and a second contact angle therebetween in the longitudinal direction of the bumper stopper,
• wherein the second contact angle is smaller than the first contact angle and the second upper and lower reinforcing blocks are disposed from the parting line with a predetermined angle along the circumferential direction of the bumper stopper.

A bump stopper for a suspension system that has at least a parting line along a longitudinal direction of the bumper stopper, comprising:

• at least two convex portions coaxially connected each other in the longitudinal direction of the bump stopper and contacting each other in a compressed state;
• a first array comprising first reinforcing blocks integrally formed on the respective convex portions along the parting line, each abutting first reinforcing block having a first contact angle therebetween in the longitudinal direction of the bumper stopper;
• and
• a second array comprising second reinforcing blocks integrally formed on the respective convex portions, each abutting second reinforcing block having a second contact angle therebetween in the longitudinal direction of the bumper stopper,
• wherein the first array is disposed with a predetermined angle from the parting line along a circumferential direction of the bumper stopper.
