500€ - 2000€
The center airbag, also known as the far-side airbag or inter-occupant airbag, is a major automotive passive safety innovation. Usually positioned in the inner bolster of the driver's seat or in the center console, it deploys between the two front occupants during a collision. Its primary objective is to prevent the driver and passenger from violently colliding with each other, particularly in the head and torso areas, during a side impact. This technology is particularly effective in far-side impact scenarios, where the body can be projected significantly across the cabin. By creating a flexible protective barrier, the center airbag limits the lateral movement of occupants, thereby reducing the risk of severe head and chest trauma. Its introduction has been widely encouraged by the tightening of safety test protocols, such as those of Euro NCAP, which now evaluate the interaction between passengers during a crash. Increasingly common in new vehicles, it complements the action of front, side, and curtain airbags to provide 360-degree protection.

The center airbag represents one of the most significant advancements in automotive passive safety in recent years. Less well-known than its frontal or side counterparts, its role has nevertheless become essential to guarantee optimal occupant protection. It is an airbag that deploys between the driver and the front passenger to prevent them from colliding in the event of an accident.
How does the center airbag work?
Unlike frontal airbags housed in the steering wheel and dashboard, the center airbag is most often integrated into the inner side of the driver's seatback or, more rarely, into the center console. Using lateral acceleration sensors, the vehicle's electronic control unit detects a severe side impact. Within milliseconds, it commands the deployment of the center airbag, which forms a protective barrier between the two front passengers. Its deployment is synchronized with that of other restraint systems, such as side airbags and seatbelt pretensioners, for maximum effectiveness.
What are the benefits of the center airbag?
The introduction of this equipment has made it possible to address a very specific safety issue: injuries caused by occupant-to-occupant interaction. Its benefits are numerous:
- Prevention of head-to-head impacts: This is its primary role. In the event of a side collision, it prevents the driver and passenger from striking each other, drastically reducing the risk of severe head trauma.
- Protection during far-side impacts: When a vehicle is struck on the passenger side, the driver's body is projected laterally toward the center of the cabin. The center airbag restrains them and protects them from an impact against the center console or the passenger.
- Improved occupant positioning: By limiting the lateral movement of the torso and head, it maintains the occupant in a safer position, allowing other airbags (curtain, side) and the seatbelt to function optimally.
- Better safety ratings: Crash-test organizations such as Euro NCAP have integrated far-side impact tests into their protocols. The presence of a center airbag has become virtually indispensable for a vehicle to achieve the maximum 5-star rating.
Is the center airbag standard equipment?
Initially reserved for high-end vehicles, the center airbag is rapidly becoming widespread. Driven by the pursuit of Euro NCAP stars, many manufacturers now include it as standard across a large part of their lineup, including on recent city cars (such as the Honda Jazz or Toyota Yaris). On other models, it may be offered as an option, often within a safety pack (Safety Pack) that groups together several driving aids and advanced protection equipment. Its cost, when optional, is integrated into a package whose price can range from €500 to over €2,000 depending on the manufacturer and the technologies included.
Conclusion: One step closer to comprehensive safety
The center airbag is not a mere gadget, but an essential component of modern passive safety. By specifically addressing the risk of injuries from occupant-to-occupant interaction, it completes the existing protection arsenal and proves that automotive safety innovation continues to progress. When purchasing a new or recent used vehicle, checking for the presence of this equipment is an excellent reflex to ensure the highest possible level of protection for oneself and one's passengers.

Curtain airbags
Curtain airbags, also known as 'curtain airbags' or Inflatable Tubular Structure (ITS), are essential passive safety devices in modern vehicles. Integrated into the headliner (roof lining) above the side windows, they deploy vertically downwards, like a curtain, in the event of a severe side impact or rollover. Their primary objective is to protect the heads of occupants, whether seated in the front or the rear, by creating a protective cushion between their heads and hard interior surfaces, such as windows, door pillars (B-pillar, C-pillar), or external objects. Unlike front or side airbags (which protect the thorax), curtain airbags remain inflated longer (several seconds) to provide continuous protection during multiple impacts or rollovers, and to prevent passenger ejection. Triggered by lateral acceleration sensors and gyroscopes, they are an integral part of the Supplemental Restraint System (SRS) and are a major criterion in safety assessments such as Euro NCAP. Today, they are virtually standard on new cars sold on the French market.
ESP
ESP, or Electronic Stability Program, is an essential active safety system in modern vehicles, also known as Electronic Stability Control. Its primary role is to keep the vehicle on the trajectory intended by the driver, by preventing loss of grip and skidding. To do this, the ESP uses a series of sensors (wheel speed, steering wheel angle, lateral acceleration, yaw) that continuously analyze the consistency between the direction desired by the driver and the actual behavior of the car. If a discrepancy is detected, signaling the onset of understeer (the front wheels skid) or oversteer (the rear wheels skid), the system intervenes in a fraction of a second. It independently brakes one or more wheels and can also reduce engine power to bring the vehicle back onto the correct trajectory. Mandatory on all new vehicles sold in Europe since 2014, ESP is an electronic guardian angel that significantly increases safety during emergency avoidance maneuvers, in tight corners, or on slippery surfaces (rain, snow, ice). It works in synergy with other aids such as ABS and ASR (traction control).
Safety Pack
The Safety Pack is a bundle of driver-assistance equipment and technologies (ADAS - Advanced Driver-Assistance Systems) grouped together by car manufacturers to improve a vehicle's active and passive safety. Rather than offering these options individually, brands market them as a package, often at a more attractive price. The main objective is to prevent accidents by assisting the driver in critical situations and to reduce the severity of collisions when they are unavoidable. A typical Safety Pack includes features such as automatic emergency braking, which can detect pedestrians and cyclists, lane departure warning with lane keep assist, blind-spot monitoring, and adaptive cruise control. The content and naming of these packs vary considerably from one manufacturer to another (e.g., Drive Assist Pack, Safety Plus Pack, etc.), but their purpose remains the same: to offer a higher level of protection for the driver, passengers, and other road users. These systems rely on a combination of sensors, radars, and cameras to continuously analyze the vehicle's surroundings and anticipate potential hazards.
Frontal airbags
Frontal airbags are a fundamental passive safety feature in modern vehicles. Designed to protect the driver and front passenger in the event of a frontal or near-frontal collision, they are an integral part of the Supplemental Restraint System (SRS). Their function is to deploy in a fraction of a second to create a cushioning pad between the occupant and the rigid parts of the cabin, such as the steering wheel or dashboard. The system is activated by sensors (accelerometers) that detect sudden and sharp deceleration, which is characteristic of an impact. An electronic control unit analyzes these signals and, if the crash is deemed sufficiently severe, triggers a pyrotechnic gas generator. This produces a large amount of gas (primarily harmless nitrogen) that inflates the nylon bag in less than 50 milliseconds. Modern frontal airbags are often adaptive (dual-stage or multi-stage), adjusting their deployment force based on the severity of the crash, seat position, or even the occupant's weight. They are designed to work in synergy with the seatbelt, which remains the primary restraint device.
Side airbags
Side airbags are an essential passive safety feature in modern automobiles, belonging to the Supplemental Restraint System (SRS). Their mission is to protect occupants in the event of a side collision, one of the most dangerous situations. There are two main types: the thorax airbag, generally integrated into the side of the seat backrest, and the curtain airbag, housed in the vehicle's headliner above the windows. During a side impact, pressure sensors and accelerometers send information to the Electronic Control Unit (ECU). Within milliseconds, if the impact is deemed severe, the ECU triggers deployment. The thorax airbag forms a protective barrier for the torso, abdomen, and pelvis. Simultaneously or independently, the curtain airbag deploys like a curtain along the windows, protecting the heads of front and rear passengers against impact with the glass, door pillar, or external objects. This technology has drastically reduced the severity of head and chest injuries, contributing significantly to achieving high crash-test ratings, notably those of Euro NCAP.
