need help to identify parts
 

The following are the parts I have found inside my car while cleaning. The picture is showing both sides of these 3 parts.
I have no idea where they came from but would like to put them back.
Does anyone have any thoughts about this ?
part numbers from left to right are
124 919 16 20,
124 919 15 20,
124 899 00 14.

Sounds like some protection of the seats attachment on the floor

The light colored ones look like seat belt harness covers...

These are not protection of the seats attachment on the floor.
I checked 10 times under the seats and there is no place for them.
What G-Benz is saying may be correct.
I will see tomoroow.

124 919 16 20 - covering rear left, right seat
124 919 15 20 - not listed for the US cars
124 899 00 14 - bracket, jack fixture
This is from EPC for the US midels.
