Passive safety

Action of a security system of procon-ten is presented by shooters. The provision of a steering column and steering wheel after head-on collision is in addition represented in red color.

Audi 80 can be considered as especially safe car thanks to comprehensive optimization of rigidity of a body to serial installation developed by Audi, the procon-ten systems and also the additional protection of sidewalls of doors.

At head-on collision the original solution of a design of longerons is of great importance. In the Audi 80 car they are designed in such a way that at collision are deformed, absorbing energy of blow. Blow force, besides, dissipates through the bearing system.

Despite the fastened belt, at heavy head-on collisions there is a danger of the damages resulting from blow of the driver about a steering wheel. In case of similar collision of procon-ten provides withdrawal of a steering wheel forward – that is from area of possible blow. At the same time seat belts so forward passengers experience rather small strain stretch.

To protection of passengers at side crash serves the following measures:

  • Application of thresholds with the increased rigidity degree. Stable a traverse in the field of the dashboard.
  • Average racks with big cross section are closed in the power scheme with thresholds and a roof.
  • Traverses do a body to more rigid in the field of front and back seats.
  • Doors with the strengthened area of the lock provide uniform transfer of force.
  • Doors come on surrounding them bodies with an overlap are resistant. Thanks to power isolation they can give big loadings.
  • The similar arrangement of forward doors with an overlap prevents jamming of doors at strong deformation of a body.
  • Additional side protection from rigid aluminum alloy in all four doors increases safety.
