Passive safety

Action of system of safety procon-ten is presented by arrows. Position of a steering column and a steering wheel after a head-on collision is in addition represented by red colour.

Audi 80 can be considered as especially safe car thanks to universal optimisation of rigidity of a body to serial installation developed Audi, systems procon-ten, and also additional protection боковин doors.

At a head-on collision the great value has the original decision of a design of longerons. In car Audi 80 they are designed in such a manner that at collision are deformed, absorbing energy of blow. Force of blow, besides, dissipates through bearing system.

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

Protection of passengers at lateral collision is served by following measures:

  • Application of thresholds with the raised degree of rigidity. Stable a traverse in the field of the instrument panel.
  • Average racks with the big cross-section section are closed in the power scheme with thresholds and a roof.
  • Traverses do a body by more rigid in the field of forward and back seats.
  • Doors with the strengthened area of the lock provide uniform transfer of force.
  • Doors come on racks of a body surrounding them внахлест. Thanks to power isolation they can transfer the big loadings.
  • The similar arrangement of forward doors внахлест prevents jamming of doors at strong deformation of a body.
  • Additional lateral protection from a rigid aluminium alloy in all four doors raises safety.
