The pictures of the escutcheon is not broken. The break allows the seat belt to be put in place, prior to clipping it in place. You can see the bits of plastic on the underside that clip onto the metal part of the seat belt assembly.

You can see the metal letter box rectangular aperture that the escutcheon fits into. You can also just see the bit where the wood gets in the way. (Upper bit)
