Abstract

A gas spring is provided in an illustrational example between a framework and a trunk cover of a motor vehicle for compensating for the weight of the trunk cover during movement of said trunk cover. The gas spring is hinged to the framework and to the trunk cover. For eliminating the spring force action on the hinge between the trunk cover and the gas spring in the closed position of the trunk cover, the part of the gas spring hinged to the trunk cover is supported on the framework, when the trunk cover is in its closed position. Alternately, the gas spring is locked when the trunk cover is in its closed position.
