Hi guys!
I've found this part after car wash and can not find from where the worker was remove it to clean. The worker of car wash service was fired and I can't ask him plz help me
Where did you find it? That might give some clue as to where it came off. The 2nd pic looks like it might be a rail cap/cover, but the size is a little large. I believe the backside of the front seats have plastic caps/covers over the rails they slide on. I'll try an take a look.
