Road vehicle, particularly passenger car, has crash-active transverse support integrated with its longitudinal ends in body shell structure, where crash-active transverse support is tunnel bridge extended in vehicle longitudinal direction

摘要

The road vehicle (1) has a body shell structure (2) with a crash-active transverse support (3) and a pyrotechnic unit (8), which moves in the event of a crash in a cross-sectional enlargement of the transverse support. The crash-active transverse support is integrated with its longitudinal ends (9) in the body shell structure and is arranged free-standing between its longitudinal ends. The crash-active transverse support is a tunnel bridge (11) that extends in the vehicle longitudinal direction and is bridged below an open tunnel (12) provided in a lower base (13) of the vehicle.
