Checking the 3-point automatic-reel belt: Notes

WARNING: This page is about a different car, the 2019 MINI Cooper, 2018 MINI Cooper, 2017 MINI Cooper, 2016 MINI Cooper, and 2015 MINI Cooper. However, it is still accessible from the selected car via links, so may be relevant.

General considerations when checking safety belts: 

  1. After replacing the EMA/REMA* electrically motorized reel 

    * EMA = electromotive automatic (safety belt) reel

    *REMA = reversible electromotive reel

    Check the additional functions for functionality when replacing the EMA/REMA electrically motorized reel after programming/coding the vehicle.

    For the EMA/REMA electrically motorized reel functional check, it is sufficient to check that the belt slack* has been eliminated.

    * Belt slack is safety belt play when the safety belt is fastened. When the safety belt is fastened, it does not immediately lie taut against the body.

    Check if belt slack was eliminated for REMA as follows:

    • Lock left seat belt buckle contact and perform functional check with diagnostic system.
    • Alternatively, take a test drive at a speed of > 10 km/h

    The electrically motorized reel is completely maintenance-free and must not be opened.

  2. After an accident 

    The safety belts must be checked after an accident.

At the beginning of the check, attempt to obtain information about the occupation of the seats in the vehicle that was involved in an accident. If this is not possible, check all of the safety belts in the vehicle and replace them if necessary.

In the event of deformations on the vehicle, you must subject the restraint system components affected in this area to a functional check and a visual inspection, including:

IMPORTANT: If you are in any doubt as to the unimpaired operability of restraint system components, these components must be replaced in the interests of safety!

If a safety belt has to be replaced following an accident (e.g. in the event of a frontal and/or oblique collision with permanently deformed impact absorbers/deformation elements or cross-members), the complete safety belt must be replaced! The complete safety belt comprises:

The following must also be checked and replaced, if applicable:

IMPORTANT: Alignment tests on the seat and the seat rails are not permitted!

The following explanations and the CHECKLIST  for the 3-point automatic-reel safety belt may be helpful.

An unusable safety belt or a safety belt worn in a serious accident should be destroyed immediately after removal to guarantee that it can not be used again.

Check the electrically motorized reel and seat belt strap: 

The electrically motorized reel has two independent activation systems for seat-belt locking.

The first activation system locks the electrically motorized reel when driving quickly around curves, driving in tight curves, on extreme inclinations (vehicle rolls over) and during sharp braking or crash.

To check, the backrest must be placed in the upright position and both hands held in a supporting position close to the steering wheel. The brakes are then operated with full intensity while driving on a dry roadway and at double walking speed.

The safety belt must lock.

The second activation system provides additional safety and is controlled by inertial mass.

If the reel locks when the seat belt strap is pulled out suddenly, this system is also OK.

In addition, the electrically motorized reel (EMA/REMA) must eliminate belt slack.

Check whether an attempt was made to eliminate belt slack:

If belt slack was not eliminated, the procedure described below must be followed:

Replace the faulty or activated electrically motorized reel.

The electrically motorized reel is completely maintenance-free and must not be opened.

Precondition for complete, problem-free retraction of seat belt straps:

When placed to one side, the seat belt straps of the front seats must retract fully.

With the seat belt straps in the rear seat bench, a small remaining loop in the seat belt strap is acceptable due to increased friction between the seat belt strap and the rear seat bench cover if:

The seat belt strap should only be cleaned with a lukewarm soap solution or a commercial mild detergent.

Seat belt strap must never be cleaned chemically or dyed.

The electrically motorized reel and seat belt strap must be replaced in the event of:

  1. creasing
  2. unraveling
  3. pinches
  4. cracks and tears
  5. traces of melting
  6. Traces of wear on the coating of the buckle tongue or on the seat belt guide loop.

Check the lower strap (belt tensioner): 

To fasten a safety belt, the buckle tongue should insert easily and engage in the seat belt buckle with an audible click.

When the "Red button" is pressed, the buckle tongue must be ejected from the seat belt buckle under spring pressure.

If the seat belt buckle cover is missing or damaged, the lower strap must be replaced.

Replace the activated belt tensioner including the complete safety belt with seat belt height adjustment and mounting bolts and check the

Criteria for an activated mechanical belt tensioner:

Criteria for an activated pyrotechnic belt tensioner:

The belt tensioners can be activated under certain circumstances even when the seat is not occupied. If it is definite that the seat belt system was not used (seat was not occupied), there is no need to replace the following components after a check.

Checking end fitting pretensioner: 

Replace the triggered end fitting pretensioner including the complete safety belt with seat belt height adjustment, lower strap and mounting bolts and check the

Criteria for a triggered end fitting pretensioner:
