I finally found a description for most of the Airbag type codes. Here is what I have:
2F - 2 Front airbags
2L - 2 Side airbags
2T - Curtain airbags
2P - Seat Belt Pretensioners (driver + passenger)
I - Switch to disable the passenger Airbag
S - Front Seat Passenger detection system

So, if the name of your airbag ECU has "2F-2P-I", it means that it has capabilities for 2 front airbags, 2 pretensioners and a switch to exclude passenger airbag.
Also, have in mind that these are the capabilities of the ECU. You may have only a driver airbag although the ECU supports 2 front airbags.
