seatbelts locked?!

[pete b]

recently had a lil bang, one of the airbags came out and now both back right and middle seatbelts in the back are locked in? probably a safety mechanism but how do you unlock them? cheers

Has it got pre tensioners in the back? If so you have to replace them if they went off.

They definately need replacing.
