Device for protecting a high-pressure gas tank of a motor vehicle
The invention provides a device for protecting a high-pressure gas tank of a motor vehicle. The device includes at least one heat-conducting plate and a thermal triggering unit. The heat-conducting plate has a distal region and a proximal region. The proximal region is arranged immediately adjacent to the thermal triggering unit and the distal region is arranged at a distance from the thermal triggering unit. The heat-conducting plate may be shaped so that it tapers from the distal region to the proximal region. The proximal region itself may be shaped in a tapering fashion. The heat-conducting plate may include heat-conducting fibers.
