Abstract
Spring-and-damper assembly articulated at a front hood and body of a motor vehicle and has, in a cylinder, a gas pressure damper with a damping piston, a piston rod outwardly loaded by the gaseous medium through an axial opening in the cylinder and assists opening of the front hood. An actuator activated by a sensor device to adjust the front hood into a raised pedestrian protection position. The piston rod or the cylinder or a structural component part is axially adjustable relative to a supporting part supporting the assembly to be limited between stops. The structural component part or supporting part is a ball head supported in a joint socket or a joint head having a joint socket for a ball head connected at least indirectly to the piston rod or to the cylinder. The joint socket is formed so as to be groove-shaped in axial direction so that the ball head is axially adjustable in the joint socket in a limited manner.
