Passive safety

Action of a security system of procon-ten is presented by shooters. The provision of a steering column and steering wheel after a head-on collision is in addition represented in the 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, procon-ten systems and also the additional protection of sidewalls of doors.

At a 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.

Protection of passengers at a side crash is served by 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 lobbies and back seats.
  • Doors with the strengthened area of the lock provide uniform transfer of force.
  • Doors come on the body racks surrounding them with an overlap. 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 lateral protection from a rigid aluminum alloy in all four doors increases safety.
