Rotary joint for vehicle door, has rotating element, and pyrotechnic element generating propulsion gas acting on connection element during ignition such that force-fit connection between individual parts of rotating element is detached

摘要

The joint has a rotating element (10) arranged at a body in a fixed manner, and another rotating element arranged at a door in a fixed manner. The former element is designed as a multi-part, where individual parts (12, 14) of the former element are connected with one another in a force-fit manner over a connection element (16). A pyrotechnic element (24) generates propulsion gas acting on the connection element during ignition such that force-fit connection between the individual parts is detached, where the connection element is designed as a bolt.
