Stefan,

You cannot subset the features within a shapefile with ogr2ogr, you need
to copy the subset to a new shapefile.

So instead use:

  ogr2ogr -spat 3500000 5300000 3540000 5400000 out.shp rastervorlage.shp

Once complete you can delete the original, and rename the new to the
original if you want.

Best regards,
