lost under car seat, i cant get it out!

[blakxhart]

hey everyone,
today i dropped something and it went underneath the passenger car seat. sorry that i dont really know any of the proper terms, but its gone into this small gap under a metal thing which the seat looks like it slides back and forwards on. i reached for it and accidently pushed it in further, and now i really have no idea how to get it back out. is there anyway the seat might tilt backwards or something, to give me better access? =\
any help would be great, thanks
