  • AUTOMOTIVE BODY SHELL
    Publication number: 20180186411
    Abstract: An automobile body shell comprises a composite underbody component (20) being made of carbon-fibre-reinforced plastic material (CFRP) and rocker panels (30) connected to the composite underbody (20) component at outer sides thereof. The rocker panels (30) are made of metallic material. Thereby the automobile body shell can be optimized namely in obtaining a stiff passenger cell (10) in combination with rocker panels (30) which can more effectively deform under impact forces.

  • Arrangement of a fuel tank in the rear region of a motor vehicle
    Patent number: 4621822
    Abstract: A fuel tank configured for universal use in the rear region of motor vehicles beneath the vehicle floor is mounted so that it can yield in the case of a rear deformation caused by an accident. The fuel tank is connected firmly to parts fixed to the vehicle in the forward region of the fuel tank in the direction of travel and is retained laterally in the rear region of the fuel tank in the direction of travel by guide bolts or the like in guides with slots open towards the rear, the guides being fixed to the vehicle frame and extending horizontally in the longitudinal direction of the vehicle, so that upon rear impact, foreshortening of the vehicle frame causes the guide bolts to leave the guide slots resulting in downward rotation of the rear part of the fuel tank.
