BRIEFING
Front seats
The front seat structure was designed to help and integrate the protection offered by the system. Two robust, coaxial
tubes arranged at the front, and one at the back, covered by the front seat cushion, restrain the occupant correctly in
frontal collisions and minimise seat distortion in lateral collisions. The front tube and PPE (polypropylene) block
embedded in the foam of the cushion protect from the so-called "anti-submarining" effect, that is prevent the occupant
from slipping underneath the seatbelt. A robust two-sided hinge between the backrest and the bottom was designed
to optimise restraining performance in low speed, rear-end collisions. This feature, in combination with appropriately
lighter side panel areas, gradually absorb the energy of high speed, rear-end collisions in a controlled fashion.
Rear seats
The backrest frame has a tough tubular structure and is designed to withstand the forces of a frontal collision with
occupants on the rear seat and/or loads in the boot. The front part of the cushion presents a raised reinforcement to
prevent submarining also for rear seat passengers.
Two ISOFIX mountings for child safety seats are standard for all outfits on the side rear seats. These anchoring
devices have two peculiarities:
they incentive continuous and correct use the child safety seat providing two fasteners on which to clip and
anchor the child safety seat
they standardise the dimensions of attachments and their distance so that the child safety seat can be used
on any type of vehicle.
ISOFIX mountings are therefore characterised by standard dimensions and reciprocal distance. These mountings are
firmly installed on rear seat backrests. The robustness of the backrest and the bodyshell anchoring ensure correct
use of the child safety seat in all collisions, therefore offering adequate protection to the child.
Head restraints
All outfits fit standard, height adjustable, locking head restraints on front seats and three head restraints on rear
seats. Some Alfa 159 versions also fit an 'anti-whiplash' device that in the event of rear-end collisions move the head
restraint towards the occupant's neck.
