198001517 - 7045 FRONT SEATS

INTRODUCTION

The seats are of vital importance in terms of comfort and safety: they are, in effect, the element that has to absorb the kinetic energy acquired by the body through the effect of stresses when cornering and during acceleration/deceleration.The front seats, in the front part of the seating area, have an excellent structure for anti-submarining, to prevent the body sliding forward under the seat belt in the case of severe frontal impacts. This also contributes in great measure to limiting injury to the abdomen and femur by reducing the body''s forward acceleration.The vehicle is equipped with up-to-date devices to ensure the achievement of lasting comfort. These were designed on conjunction with the CONI Sport Medicine Institute biomechanical department.To enhance vibrational comfort and especially the absorption of vibrations produced from the road surface (e.g.: tram lines, etc.) the seats are equipped, in the area of the gluteus ischium-coccyx, with an efficient spring system with a flexible pack made up of thin steel wires coated in plastic and secured by two clips to the perimeter frame;To improve back support, the vehicle has a modern support system for the lumbar region specially designed to adapt fully to the back and support it tirelessly thanks to its considerable extension and operating range.In addition the driver''s seat is height adjustable by means of a ratchet lever with extremely reduced operating loads and is very easy to use.The guides slide lengthwise, with a travel of 220 mm (210 mm on the electric version) and an operating lever on the tunnel side. They are a slight angle of 3° to raise the seat slightly when it is moved forwards.The combination of the seat height adjustment with the height and axial adjustment of the steering wheel makes it possible to produce the optimum driving position for an extremely wide range of drivers.The adjustment of the backrest angle is continuous and is regulated by a knob located in the area of the seat towards the outside of the passenger compartment.The lumbar support of the driver''s seat can be adjusted using a knob located on the outside of the seat, controlling a mechanism that varies the carrying capacity of the backrest lumbar area to ensure improved comfort.

Structure

The structure of the front seats has been designed to assist and complete the protection offered by the occupant protection system. Two metal bars, located at the front and rear under the front seat cushion, maintain the correct support of the occupant in a frontal impact and minimize the distortion of the seat in side impacts. The front crossmember and the configuration of the seat prevent the passengers from sliding underneath the seat belt known as the anti-submarining effect.The bilateral type robust hinging between the backrest and the base of the cushion structure has been designed to ensure optimum retention of the occupant in the case of rear impacts at low speed and, in conjunction with suitably designed side panels, gradually absorb the impact energy from rear collisions at high speed in a controlled manner.

Heated seats

The button in the centre console, in the area of the gear lever, controls the operation of two heater pads in the cushion and in the backrest.

Head restraint

In rear impacts at low speed the most common injury is whiplash. To reduce the risk of this injury to a minimum, the vehicle is fitted with head restraints capable of retaining the head in the case of rear impacts preventing irregular or excessive stresses to the cervical group of the vertebral column. The size of the head restraint in relation to the position of the neck and the stiffness of the head restraint are therefore important with regard to the performance of this function.The following goals were set for this vehicle:- To minimise the distance between neck and head restraint- To ensure the adjustment range was sufficient to accommodate even very tall people.- Great stability during impact.The front head restraints have a height adjustment device with a fastening to ensure stable and optimum positioning in all intermediate positions.The adjustment control does not have to be released to raise the head restraint.To lower the head restraint, on the other hand, it must be released using the button on the bush. When the head restraint button is released, it will lock in the nearest position.

Anti-whiplash device

To increase safety in the event of rear impact, an antiwhiplash device is available as an option. This reduces the distance between head and head restraint following an impact.The seat is fitted with a sprung device that allows the head restraint to be brought closer to the occupant''s head in the event of rear impact and consequent pressing of the back against the backrest. This limits damage due to whiplash.

Electrically-adjustable seats

The front seats are also available with electric movement and adjustment using ergonimic interface controls.
There are controls for adjusting the seat at the base of both seat on which the following are located. This function is activated with the ignition ON; also, when the front doors are opened, the seat next to the door which has been opened can be moved for about 3 minutes or until the door is closed.Button A: seat lengthwise and height adjustmentButton B: backrest angle adjustment and lumbar adjustmentUsing only 2 multifunction buttons the seat can be adjusted as necessary and adapted to suit all tastes and requirements.
