Door frame module for a modularly structured motor vehicle door and modularly structured motor vehicle door comprising such a door frame module

In order to best exploit the advantages of modular system construction for vehicle doors, a door frame module (2) is proposed which, as a component separate from a body-in-white module (1), can be placed onto the body-in-white module via a support frame (5) and forms a fastening receptacle for a functional module (3) that is separate from the door frame module and is to be placed onto the door frame module on the inside.
