Dacia Bigster
Depending on the vehicle, they may comprise:
- front seat belt inertia reel pretensioners;
- chest force limiters;
- airbags driver and passenger front.
These systems are designed to act independently or together when the vehicle is subjected to a frontal impact.
Depending on the severity of the impact, the system can cause:
- blocking of the seat belt;
- the seat belt pretensioner to hold the occupant in the seat, in addition to the force limiter;
- the front airbag.
Pretensioners
The pretensioners hold the seat belt against the body, holding the occupant more securely against the seat, thus increasing the seat belt's efficiency.
With the ignition on, following a significant frontal impact and depending on the severity of the impact, the system may trigger the seat belt inertia reel pretensioner 1 which instantly retracts the seat belt.
Load limiter
Above a certain level of impact force, this mechanism is used to limit the force of the belt against the body so that it is at an acceptable level.
warning
- Have the entire restraint system checked following an accident.
- No operation whatsoever is permitted on any part of the system (pretensioners, airbags, computers, wiring) and the system components must not be reused on any other vehicle, even if identical.
- Only qualified personnel from our Network may work on the airbags; otherwise the system may trigger accidentally and cause injury.
- The electrical trigger system may only be tested by a specially trained technician using special equipment.
- When the vehicle is scrapped, contact an approved dealer for disposal of the pretensioner and airbags gas generators.
driver and passenger front Airbags
These are provided for the driver and the front passenger seats (location A).
A "Airbag" mark on the steering wheel, dashboard (airbag area A) and, depending on the vehicle, a label at the bottom of the windscreen provide a reminder that this equipment is present.
Each airbag system consists of:
- an airbag and gas generator fitted on the steering wheel for the driver and in the dashboard for the passenger;
- an electronic unit for monitoring the system controlling the gas generator electrical trigger;
- a single warning light
on the instrument panel; - remote sensors (depending on the vehicle).
warning
The airbag system uses pyrotechnic principles. This explains why, when the airbag inflates, it will generate heat, produce smoke (this does not mean that a fire is about to start) and make a banging noise. In a situation where an airbag is required, it will inflate immediately and this may cause some minor, superficial grazing to the skin or other problems.
Operation
This system is only operational when the ignition is switched on.
In the event of a severe frontal impact, the airbag(s) inflate rapidly, cushioning the impact of the driver's head and chest against the steering wheel and of the front passenger against the dashboard. They then deflate immediately so that the passengers are not in any way hindered when leaving the vehicle.
Operating faults
This warning light comes on when the engine is started and then goes out after approximately three seconds.
If it does not come on when the ignition is switched on or if it stays on, there is a fault in the system.
Contact your approved Dealer as soon as possible;
Your protection will be reduced until this fault is rectified.
The following cases trigger the pretensioners or the airbags :
In a frontal impact against a rigid (non-deformable) surface at an impact speed equal to or greater than 16 mph (25 km/h) km/h.
In a frontal impact with another vehicle of an equivalent or higher category, with an impact area equal to or greater than 40%, where the speed of both vehicles is equal to or greater than 25 mph (40 km/h) km/h.
In a side impact with another vehicle of an equivalent or higher category, at an impact speed equal to or greater than 31 mph (50 km/h) km/h.
In the following examples, the pretensioners or airbags may be triggered:
- impacts to the underside of the vehicle, from kerbs;
- potholes;
- a fall or a hard landing;
- stones;
- ...
The pretensioners or airbags may not be triggered by:
- a rear impact, however severe;
- the vehicle overturning;
- side impact at the front or rear of the vehicle;
- frontal impact, underneath the tail of a lorry;
- frontal impact against an obstacle with a sharp angle;
- ...
Warnings
All of the warnings below are given so that the airbagis not obstructed in any way when it is inflated and also to prevent the risk of serious injuries caused by items which may be dislodged when it inflates.
warning
Warnings in relation to the driver's airbag
- Do not modify the steering wheel or the boss.
- Do not cover the steering wheel boss under any circumstances.
- Do not attach any objects (badge, logo, watch, telephone cradle, etc.) to the steering wheel boss.
- The steering wheel must not be removed (except by qualified personnel from our Network).
- Do not sit too close to the steering wheel: adopt a driving position whereby your arms are slightly bent Seat belts. This will allow sufficient space for the airbag to deploy correctly and be fully effective.
Warnings in relation to the passenger airbag
- Do not attach or glue any objects (badge, logo, clock, telephone holder, etc.) to the dashboard on or near the airbag.
- Do not place anything between the dashboard and the passenger (animal, umbrella, walking stick, parcels, etc.).
- The passenger must not put his or her feet on the dashboard or seat as there is a risk that serious injuries may be sustained. As a general rule, keep all body parts (knees, hands, head, etc.) away from the dashboard.
- Reactivate the passenger airbag as soon as you remove the child seat to ensure the protection of the front passenger in the event of an impact.
A REAR-FACING CHILD SEAT MUST NOT BE FITTED TO THE FRONT PASSENGER SEAT UNLESS THE ADDITIONAL RESTRAINT SYSTEMS ARE DEACTIVATED Child safety: deactivating, activating the front passenger airbag.
