Patent number: 4595182Abstract: A flap member, e.g. a trunk lid of a motor vehicle, is pivotally mounted on a framework, e.g. a motorcar framework. The flap member is assisted in its upward movement by a gas spring. The thrust of the gas spring biases the flap member towards an upper position. In this upper position further upward movement of the flap member is locked by a relief pressure valve between the working chambers of the gas spring. By applying external force to the flap member assisting the thrust of the gas spring, the flap member may be moved beyond said upper position while opening said relief pressure valve. If the external upward directed force ceases the relief pressure valve closes again and the flap member is maintained in the new position by the thrust of the gas spring and the locking action of the relief pressure valve. When the flap member is to be lowered, an external force is applied opposite to the trunk lid and as a result thereof a direction-responsive is opened in parallel to the relief pressure valve.Type: GrantFiled: January 5, 1984Date of Patent: June 17, 1986Assignee: Stabilus GmbHInventors: Herbert Freitag, Gerhard Reichert
