Abstract
A pneumatic device for pivoting a pivotal component is articulated to a structural element by means of a joint. Hoses produced from a material of low ductility, to which compressed air can be admitted, are inserted between the pivotal component and the structural element. The hoses contain an airtight bag. When these bags are inflated via valves, compressive forces act both on the structural element and on the pivotal component, causing the latter to swivel out. In order that the hoses cannot migrate, webs run from the joint to the hoses. In order to relieve the hoses in a specific limit position of the pivotal component and to prevent oscillatory movements of the pivotal component, a locking device is provided. The locking device includes a rod, which runs through a brake device fixed to an arm.
