Welcome to the essential deconstruction of the Ensemble de ceinture de sécurité FAW J6P Pour le FAW Jiefang CA3250P66K2L1T1E 6×4 tombereau. This is the most critical passive safety system in the vehicle. Ce guide déconstruira le 4 key components, from the main retractor to the buckle and trim, ensuring flawless technician service.
Le Ensemble de ceinture de sécurité FAW J6P est un complexe, engineered safety device. It is the primary restraint system, designed to work in fractions of a second to protect the driver and passenger during a sudden stop or collision. In the demanding environment of a 6×4 tombereau, this system must withstand constant vibration and dust while remaining 100% fiable.
This deconstruction will go beyond a simple parts list. We will analyze the pyrotechnic, mécanique, and energy-absorbing logic built into each component. Pour un technicien, understanding this Ensemble de ceinture de sécurité FAW J6P is not just about maintenance; it is about ensuring the vehicle’s core safety features are intact and functional. A seatbelt is a one-time-use device in a crash, and replacing it correctly is a critical, non-negotiable task.
Ce composant est le cœur du Ensemble de ceinture de sécurité FAW J6P. It houses the belt webbing and the majority of the safety mechanisms. The Qty 2 indicates this part (or its mirrored equivalent) is used for both driver and passenger sides.
1. Composant: ‘Outer Seatbelt Assy’ (8212010-A86-C00) – Quantité 2
Ce (Marque 1) is the main retractor and webbing assembly. It is a highly complex, sealed unit that must not be tampered with. It contains multiple, distinct safety logics.
The Locking Logic (ELR): This is the fundamental feature. The assembly contains an Emergency Locking Retractor (ELR). This mechanism allows the belt to be pulled out slowly and retract freely, but it locks instantly during a sudden change in velocity (un accident) or a change in orientation (un retournement).
This is achieved mechanically, often with a small pendulum or ball-in-cage that is displaced by G-forces, triggering a locking pawl that engages the retractor’s gear. C'est le “jerk” sensitivity of the belt.
The Pyrotechnic Logic (Pretensioner): This is the active safety part of the Ensemble de ceinture de sécurité FAW J6P. This retractor contains a pyrotechnic pretensioner. Upon receiving a signal from the truck’s airbag control unit (UCA), un petit, controlled explosive charge (a gas generator) les incendies.
This gas rapidly expands, spinning the retractor spool backwards *before* the occupant has moved forward. Ce “pre-tensions” the belt, removing all slack and pulling the occupant firmly into their seat. This action is critical for positioning the occupant correctly for the load-limiting phase.
The Webbing Logic: The belt itself is a key component. Le “sangles” is made from high-tensile, woven polyester, specifically designed to stretch in a controlled, predictable way. This stretch is not a flaw; it is an energy-absorbing feature. It acts like a spring, slowing the occupant’s deceleration and reducing the peak force transferred to their chest and pelvis.
The Load Limiter Logic: This is the final and most sophisticated logic. After the Ensemble de ceinture de sécurité FAW J6P has pretensioned and the occupant’s full weight is thrown against the locked belt, an immense force is generated. To prevent the belt itself from causing severe chest or collarbone injuries, a load limiter is activated.
This is often a “torsion bar” inside the retractor spool. At a pre-set force (Par exemple, 4 kilonewtons), this bar will twist, allowing the belt to “pay out” a few centimeters in a controlled manner. Ce “yielding” action absorbs the most violent peak forces of the impact, protecting the occupant.
La logique de service: A deployed Ensemble de ceinture de sécurité FAW J6P is a deployed pyrotechnic. It is a single-use device. Once the pretensioner has fired or the load limiter has been activated (which it will be in any significant collision), the entire assembly (8212010-A86-C00) is scrap. It *must* be replaced. It cannot be “reset.”
C'est le “femelle” half of the Ensemble de ceinture de sécurité FAW J6P. It provides the secure locking point for the belt’s latch plate and communicates the belt’s status to the truck’s computer.
1. Composant: ‘Left Buckle Assy’ (8212025-A01) – Quantité 1
Ce (Marque 2) is the buckle assembly, spécifié pour le “Gauche” (driver’s) côté. This implies it is different from the passenger side, likely due to its integrated electronics.
The Latching Logic: This is the core mechanical function. The assembly contains a high-strength, spring-loaded latch mechanism. It is designed to capture the belt’s metal tongue and lock it securely with a positive “click.” The red “PRESS” button is a mechanical release that must function easily for egress.
The mechanism is designed to be “over-center” et “load-proof,” meaning the harder the occupant pulls on it during a crash, the more securely it locks. It cannot be pulled open under load.
La logique électrique (Seatbelt Switch): Ce Ensemble de ceinture de sécurité FAW J6P buckle is not just mechanical. It contains an integrated switch. This switch detects the presence of the metal latch plate. It is a simple open/close circuit that communicates with the vehicle’s body control module (BCM).
This switch is the logic that controls the “fasten seatbelt” warning light and audible chime on the dashboard. A failure of this switch (Par exemple, light stays on even when buckled) is a common diagnostic item.
The Structural Logic: This buckle assembly is not bolted to the seat fabric. It is mounted via a short, high-tensile steel cable or a solid steel stalk, which is then bolted directly to the high-strength steel frame of the driver’s seat. This anchor point is just as strong as the retractor’s anchor.
La logique de service: Like the retractor, this component is often a single-use device. Many buckles also contain a pretensioner (using a cable to pull the lap belt down). If this Ensemble de ceinture de sécurité FAW J6P buckle has been part of a pyrotechnic deployment, il faut le remplacer. A technician must also replace it if the switch fails or the mechanical latch becomes weak or damaged.
These components are the interior trim pieces that conceal and protect the Ensemble de ceinture de sécurité FAW J6P mécanismes. They are safety components in their own right.
1. Composant: ‘Left Side Panel Fixed Cover – Seatbelt’ (8212057-A01) – Quantité 1
Ce (Marque 3) is the interior trim cover for the “Gauche” (driver’s) côté, likely covering the B-pillar where the retractor (Cœur 1) is mounted.
2. Composant: ‘Right Side Panel Fixed Cover – Seatbelt’ (8212058-A01) – Quantité 1
Ce (Marque 4) is the corresponding interior trim cover for the “Droite” (passenger’s) côté, which also houses a Ensemble de ceinture de sécurité FAW J6P rétracteur.
The Protective Logic: The most basic function of these covers is cosmetic and protective. They conceal the steel body of the cab and the retractor mechanism. They prevent dust, Débris, and moisture from fouling the Ensemble de ceinture de sécurité FAW J6P mécanisme, which could cause it to jam.
They also protect the webbing from UV light from the sun, which can degrade the polyester fibers and weaken the belt over many years.
The ‘Tear-Seam’ Logique: C'est un point critique, non-obvious safety logic. These covers are not just simple plastic. They are engineered with “tear-seams” ou “rompre” points, especially if the vehicle is equipped with side-curtain airbags.
If an airbag or the Ensemble de ceinture de sécurité FAW J6P itself needs to deploy with massive force, this cover is designed to split open in a controlled, predictable way. This allows the safety device to deploy correctly without sending plastic shrapnel into the cabin.
The Guide Logic: These covers also incorporate the upper “Boucle D” or guide for the seatbelt. This is a plastic or metal loop that guides the webbing from the retractor to the occupant’s shoulder. This loop is made of a low-friction material to allow the belt to move smoothly and, crucialement, is anchored to the steel pillar to take the full crash load.
La logique de service: A technician must use extreme care when removing these panels. Using metal tools can damage the plastic, break the mounting clips (leading to rattles), ou, most critically, damage the hidden tear-seams. After a collision, these panels must be inspected and are often replaced as part of a full Ensemble de ceinture de sécurité FAW J6P system replacement.
