Device for protecting motor vehicle passengers in event of lateral collision energy input has part with conversion material that undergoes mechanical state change on receiving energy, bringing parts into contact and/or locking them together

摘要

The door has a connecting structure with at least two parts, the first connected to the vehicle door and the second to an energy absorbing region of the body structure, and a common joint region for bringing the parts into interaction to carry away at least part of the energy acting on the door to the energy absorbing region. The first and/or second part contains conversion material that undergoes a mechanical state change when receiving energy, especially a shape change, bringing both parts into contact and/or locking them together.
