  • Patent number: 4410212
    Abstract: A motor vehicle provided with an engine space or trunk arranged in the forward end thereof and with an end wall located between the space or trunk and the passenger compartment. A brake pedal, mounted in a suspended fashion connected to a braking device located outside of the passenger compartment, extends through the end wall. The braking device is arranged so that, upon a frontal structural deformation caused by a collision, the brake device executes a pivotal motion by which the brake pedal is guided away from the driver of the vehicle and against the end wall. A two-stage deformation member is provided which includes a rigid upper pot-shaped deformation member to which the braking device is attached. A pedal shaft of the brake pedal is mounted in an upper zone of the upper pot shaped member, the upper pot shaped member passes over by way of a step or shoulder into a larger deformable lower pot-shaped member connected with the end wall.

  • Patent number: 4189177
    Abstract: A forward longitudinal bearer supported under angular bending at the end wall of a self-supporting motor vehicle body, whereby the end wall is locally bulged out in the direction toward the respective vehicle end within the connecting area of each forward longitudinal bearer in such a manner that a form-rigid body results; each forward longitudinal bearer is forked in its approach at the form-rigid body and the arms resulting therefrom at least partially surround the form-rigid body.

  • Patent number: 4057263
    Abstract: A vehicle frame consisting of longitudinal bearers with hollow profile which are interconnected near their ends by at least one transversely extending element; at least one of the edges of the longitudinal bearers is provided with intentionally weakened places for reducing the compressive strength in the end areas, which are constructed as beads or corrugations that extend preferably in the vehicle transverse direction; the beads or corrugations may thereby have their greatest depth in the area of the edges and after reaching the bearer walls adjoining on both sides thereof, run out in the plane thereof.
