Body frame for motor vehicles, esp. cars has two side pillars, roof, seat, and bridge struts to form closed support structure for increased side impact protection

摘要

The body frame has two side pillars (2), which are supported on each other via a pressure-resistant roof cross strut (3), and in the floor area are each supported via a pressure-resistant seat cross strut (5) on a longitudinal tunnel (7). The two seat cross struts are supported on each other via a pressure-resistant bridge strut (8), which bridges the tunnel. The pillars are formed as B-pillars, and one and/or all struts are pressure-resistant hollow profiles. Each pillar has a hollow body with internal tubular body of a high-strength material.
