Secured structure for motor vehicle, has folding primer placed near lower end of each of center pillars, located at maximum distance from distal part of each pillar, and allowing deformation of each pillar in case of impact with obstacle

摘要

The structure has a vertical center pillar (1) and another vertical center pillar respectively arranged on two sides of the structure, where each pillar is formed by an elongated part having a folding primer (5) placed near a lower end (6) of the pillar. The folding primer allows deformation of the pillar in case of impact with an external obstacle. The folding primer is located at a maximum distance from a distal part (8) of the pillar, where the maximum distance is less than one tenth of total length of the pillar. The folding primer is constituted by a local cavity of the pillar.
