Stop buffer

A stop buffer for absorption of kinetic energy released during a collision between objects, the stop buffer comprising:

• a carrier body movably mounted on a support body;
• a first spring body connected to the carrier body, the first spring body made of an elastic material;
• a second spring body holding the carrier body at a predefined distance from the support body by a bias of the second spring body when the carrier body is in a rest position;
• and
• a sensor including a triggering element arranged in a carrier body cavity integrally formed in a back surface of the carrier body or in a support body cavity integrally formed in a front surface of the support body such that the sensor is completely contained in at least one of the carrier body cavity integrally formed in the back surface of the carrier body and the support body cavity integrally formed in the front surface of the support body, the sensor outputting a signal when the triggering element is actuated by a force acting on the first spring body during the collision between objects, the force compressing the second spring body such that the back surface of the carrier body moves toward the front surface of the support body and stops by directly contacting the front surface of the support body.
