Technical Information
The buckle is mounted at the lower centre section of the rear bench and provides the locking point for the rear middle passenger’s seat belt tongue.
Its main functions are to:
* Secure the rear centre passenger seat belt
* Lock the belt tongue positively into position
* Maintain the correct restraint geometry
* Allow quick manual release using the buckle button
* Work with the original BMW seat belt webbing and anchorage arrangement
The buckle itself is a passive safety component and forms part of the vehicle’s occupant restraint system.
Rear Seat Belt System Information
The rear seat belt system is designed to restrain passengers during:
* Heavy braking
* Sudden deceleration
* Collision events
The buckle must securely retain the belt tongue and release only when the release button is intentionally pressed.
A damaged or contaminated buckle should not be ignored because reliable engagement of the locking mechanism is essential for correct seat belt operation.
Common Reasons for Replacement
Typical reasons for replacing this part include:
* Seat belt tongue will not lock into the buckle
* Belt releases unexpectedly
* Release button sticking
* Internal locking mechanism becoming stiff
* Broken or damaged buckle housing
* Buckle becoming trapped or damaged during seat removal
* Previous accident damage
* Missing buckle after rear seat replacement
* Incorrect buckle fitted during interior conversion or repair
Important Diagnostic Information
Before replacement, inspect both the buckle and the mating seat belt tongue.
A belt that does not latch correctly may be caused by:
* Dirt or foreign objects inside the buckle
* Bent or damaged belt tongue
* Incorrect seat belt being used
* Damaged buckle mechanism
* Misaligned mounting point
* Damage caused during previous seat removal
Do not lubricate the internal buckle mechanism unless specifically permitted by BMW repair information, as contamination may interfere with proper locking operation.
Safety Information
Seat belts are safety-critical components.
Do not use a buckle that shows signs of:
* Accident loading
* Cracking
* Heavy deformation
* Damaged mounting points
* Unreliable locking
* Unreliable release operation
After installation, insert the correct seat belt tongue several times and confirm that it locks securely and releases normally.
Installation
The buckle mounts to the original rear seat/belt anchorage position.
During installation:
* Use the original mounting location
* Ensure the buckle is not twisted
* Ensure no trim or seat foam obstructs operation
* Tighten the mounting fastener to the correct BMW specification
* Test locking and release before carrying passengers
Programming / Coding
No programming or coding is normally required.
This is primarily a mechanical seat belt latch component.
Important Compatibility Note
Please compare before ordering:
* Part number – 7243275-04
* OE reference – 72117243275
* Rear centre position
* Buckle shape
* Seat belt tongue profile
* Mounting arrangement
* Strap/bracket design
* Vehicle body type and rear-seat specification
BMW can use different rear belt components depending on vehicle specification and seat configuration, so matching the number printed on the original buckle is strongly recommended.
