h – at least 500 mm above the door opening (the distance from the top of the door opening to the ceiling)

b1/b2 – requires a lateral distance of at least 150 mm left and right (distance from the corresponding edge of the door opening to the obstacle)

L is the depth of the room

When measuring H and B, take the maximum value as the final size
When measuring h, b1, b2 and L, take the smallest value as the final size
