Seat belt device in Nissan Almera Classic: diagram and principle of operation
Seat belts in Almera Classic (as in most cars Nissan early 2000s) are built according to the classic three-point design with an inertial mechanism. Main components:
- 🔧 Лямка ремня — fabric part with metal fastening to the body.
- 🔄 Inertia coil — the belt blocks during a sharp jerk (in an accident) or during sudden braking.
- 🔒 Lock (latch) - secures the belt in the buckle.
- 🛠️ Tensioner (squib) - triggered in the event of an accident, instantly tightening the belt (not available in all trim levels).
- 📏 Height adjuster — allows you to adjust the position of the belt according to the driver’s height (only in versions since 2006).
The principle of operation is simple: with a smooth movement, the reel allows the belt to rewind/unwind freely. During a sharp jerk (acceleration > 0.7g), the inertial mechanism blocks the shaft, fixing the passenger's body. B Almera Classic N16 (2003–2012) coils are common TRW or Takata, and in B10 (1995–2000) - simpler mechanisms without squibs.
How to check the serviceability of the inertial mechanism?
Pull the belt out with a sharp jerk - it should lock. If there is no blocking or the belt “slips,” the mechanism is worn out and requires replacement. B Almera Classic This is a common problem after 150–200 thousand km.
Important: in Almera Classic 2006–2012 release, the front belts are equipped with squibs (tensioners) that operate once. After an accident, they must be replaced, even if outwardly they look good.

| Symptom of malfunction | Possible reason | Solution |
|---|---|---|
| The belt does not extend or gets stuck | Coil contamination, shaft corrosion, spring wear | Cleaning/lubricating or replacing the coil |
| Belt won't retract | Return spring failure, strap deformation | Replacing a spring or the entire mechanism |
| The lock does not secure the belt (clicks, but does not hold) | Worn plastic parts of the lock or tongue | Replacing a lock or tongue |
| The belt locks spontaneously (when turning) | Malfunction of the inertial sensor or pendulum | Coil diagnostics, replacement if necessary |
| Extraneous sounds (creaking, knocking) when moving | Wear of the reel bearings, friction of the strap on the plastic | Lubrication or replacement of the mechanism |
Most often they break front belts - due to more intensive use. In the rear seats there are problems: jamming due to infrequent use or the strap breaking (if passengers jerk the belt sharply). B Almera Classic N16 after 2008, sometimes there is a defect in the squibs (they can fire spontaneously during strong shaking).

If the belt is too long or short:
- 🔧 Pull the belt all the way and release slowly - the reel should retract the excess length.
- 🔄 If the belt does not retract, check to see if any debris (such as coins or sand) has gotten into the mechanism.
- 🛠️ As a last resort, you can disassemble the rack trim and manually tighten the tensioner (but this is a temporary solution).
Is the belt strap twisted?
Is the reel mechanism clean (no sand/dust)|
Is the lock working (the tongue should fit freely)|
Are there any cracks in the plastic fastening parts-->
B Almera Classic B10 (until 2000) height adjustment is not provided - the belt is fixed. In this case, you can purchase universal guide clips (article Nissan 80310-4M000), which are attached to the stand and change the trajectory of the belt.
