Boot Floor Assembly
This is a section of the floor between the seat panel and the extreme
back of the boot. It is strengthened by the use of cross members to
carry the rear seat passengers. This area forms the rear bulkhead
between the two rear wheel arches forming the rear seat panel or
heelboard and in a saloon body
shell can incorporate back seat
supports and parcel shelf. The boot
floor is also strengthened to
become the luggage compartment,
carrying the spare wheel and petrol
tank. At the extreme back it
becomes the panel on to which the
door or tailgate closes.
Complete Underbody Assembly
This is commonly called the floor pan assembly and is usually
composed of several smaller panels welded together to form a
single floor unit. All floor panels are reinforced on the underside
body stiffening members or cross members. Most floor pans are
irregular in shape for several reasons. They are formed with
indentations or heavily swaged areas to strengthen the floor section
between the cross members and foot room for the passengers is
often provided by these recessed areas in the floor.
