Abstract

The invention relates to a method for producing an ultrasound sensor (20) for a motor vehicle, in which method, for the ultrasound sensor (20), a diaphragm (23) for emitting ultrasound signals in an emitting direction (21) and a sensor housing (24) are provided, in and/or on which sensor housing the diaphragm (23) is fastened, wherein the sensor housing (24) has a front side (25), which points in the emitting direction (21) of the diaphragm (23), and a rear side (26), which points in a rearward direction (27) which is opposite to the emitting direction (21), and wherein the sensor housing (24) is, on the rear side (26), formed with a rear-side installation opening (29) for components of the ultrasound sensor (20), wherein the diaphragm (23) is inserted into the sensor housing (24) through the rear-side installation opening (29) in the emitting direction (21), and said diaphragm is placed, through an interior space (30) of the sensor housing (24), into an installed position at the front side (25) of the sensor housing (24), and is fastened in the installed position.
