fiesta mk5 drivers seat issue
 

Hi fellas, I wondered if any of you might be able to help, I have a mk5 fiesta lx and the drivers seat cushion keeps springing up.there appears to be 2 small square headed nuts which the mounting bolts stick out of and I presume these should fit into the tear drop holes located underneath the seat cushion but what should hold the seat down as it just keeps lifting up.
