Abstract
A vehicle frame is described which has a step-through opening, particularly for a two-wheeler, for a vehicle having a resilient front wheel suspension, a steering device for a front wheel, a resilient rear wheel suspension for at least one rear wheel, at least one seat device for a driver and at least one protection device which extends in front of, over and behind the driver and is designed such that a laterally open cage is created for the driver which permits the stepping-through, and having an engine which is mounted essentially in front of the rear wheel and below the seat device. The vehicle frame has at least one principal frame element which extends essentially in the longitudinal direction of the vehicle, specifically from the rear bottom, close to the engine, toward the front top, close to the steering device, in which case at least one further frame element is provided on each side below the principal frame element which extends at least in sections essentially in parallel to the vehicle contact surface and which forms a supporting surface for the respective foot of the driver. A safety belt device, a shoulder protection bow, a pelvis protection bow and a frame-fixed seat ramp are provided as additional safety devices.
