摘要： 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.

摘要： A spring device at a swivelable hatch of a motor vehicle, having a gas spring and a helper spring between the body of the motor vehicle and the hatch. The hatch is a front hood which can be raised into a pedestrian protection position prior to an impact of a pedestrian on the front hood, by an actuator activated by a sensor device. The helper spring is preloaded with a preloading force which, in case of a malfunction in which the gas spring has no gas pressure or a reduced gas pressure, is sufficient to adjust the front hood into the raised pedestrian protection position and to hold the front hood in the raised pedestrian protection position prior to the impact.
