Dismantling Of E46's Rear Seat

[mkmy]

salam aidilfitrimy ride is e46 2003 ckd. my problem is the middle passenger of the rear seat can't buckle up as the belt fastener is nowhere to be found and i have a feeling that it has been concealed underneath the seat. but then another problem encountered because i could not locate any bolt & nut to unsecure the seat. so, i'd appreciate it if you guys could enlighten me. tq mkmy

salam, i've never thought that it was so easy to remove the rear seat, well by simply pulling the seat upward! so, now the 3rd rear passenger can buckle up
