I have the same problem with mine, you have to lift the catch up, tilt the seats as much as it can go forwards then pull the catch up till it clicks, i thought mine was broke, but then i realised i think its to stop the person in the back seat from recieving a head rest to the nose :ninja: this would be usefull tho so they dont squirm when you try to force them in the bag :shock: but you cant have everything :shrug:
