2021-2023 Citroen C4 Seat Belts Operation
The Citroen C4’s seat belts are more than just cloth straps; they are the foundation of passenger safety and demonstrate the manufacturer’s unwavering dedication to saving lives. In the event of a collision or sudden halt, these seat belts act as the first line of defense, making them essential in preventing injuries and saving lives. Citroen has included three-point seat belts for all seating positions as part of the C4’s innovative seat belt technology. With adjustable lengths to fit passengers of all sizes, these belts are made with comfort and safety in mind. Additionally, they have pretensioners and force limiters that, when activated in an emergency, eliminate slack and distribute forces evenly across the body to lower the danger of harm. Additionally, the Citroen C4 has seat belt reminder devices to encourage everyone to wear their seat belts, ensuring that safety is always put first on every trip. In addition to being a requirement, Citroen’s unwavering dedication to passenger safety and peace of mind is symbolized by these seat belts.
Seat belts
Inertia reel
- The seat belts are equipped with an inertia reel which allows the strap length to adjust automatically to the shape of the user. The seat belt returns to its storage automatically when it is not used.
- The inertia reels are fitted with a device which automatically locks the strap in the event of a collision, emergency braking or if the vehicle rolls over. It can be released by pulling the strap firmly and then releasing it so that it reels in slightly. Pyrotechnic pretensioning
- This system improves safety in the event of a frontal or side impact.
- Depending on the severity of the impact, the pyrotechnic pretensioning system instantly tightens the seat belts against the body of the occupants.
- The pyrotechnic pretensioning seat belts are enabled when the ignition is on.
Force limiting system
This system reduces the pressure of the seat belt on the chest of the occupant, thus improving their protection.
In the event of an impact
- Depending on the nature and seriousness of the impacts, the pyrotechnic device may trigger before and independently of airbag deployment. Deployment of the pretensioners is accompanied by a slight discharge of harmless smoke and a noise, due to the activation of the pyrotechnic cartridge incorporated in the system.
- In all cases, the airbag warning lamp comes on.
- Following an impact, have the seat belt system checked, and if necessary replaced, by a CITROËN dealer or a qualified workshop.
