The partition of a cabin (fig. 10.1) — metal, continuous, has a window (is established by request) with movable glass. The partition fastens to body racks self-cut screws, the shelf of a partition fastens to roof laths bolts.
The thermonoise isolation of a cabin consists of the formed multilayered details of isolation of a guard of a front, rugs of a floor and polyurethane foam details pasted on the formed upholsteries of a roof and a partition of a cabin.
The closed surfaces of sidewalls and the basis of a body are processed by vibration-absorbing BPM-1 mastic for noise reduction and protection against corrosion. Anticorrosive processing consists in phosphate coating and the subsequent priming of a body. After primer and putting mastic external and internal surfaces are enameled two layers of ML-12 or ML-1110.
Tightness of a body is provided with application of rubber sealants of doors, hatches, glasses of doors, elements of electric equipment, levers, drives of engine management and chassis units. Glass of a wind window is pasted to an aperture by Terostat-8590 glue.
The body consists of in advance subcollected knots: bases, right and left sidewalls, front, roof, back. At assembly welding they form the power framework based on box-shaped sections. Apertures of forward doors are executed in tselnoshtampovanny sidewalls. Apertures of side and back doors compound, are formed when welding a body in conductors.
Part of details of plumage — removable. The top panel of facing of a radiator with the lock of a cowl and wings fasten to a body bolts. The cowl is established on the rotary loops fixed on a front guard by bolts.

Fig. 10.2. Fastening of a body to a frame: 1 — a nut; 2 — a washer; 3, 8 and 11 — an arm; 4 — a pillow; 5 — the expansion plug; 6 and 9 — bolts; 7 — a cap; 10 — laying of an average cross-piece
|
The body fastens to a frame (fig. 10.2) in ten points through rubber pillows and laying (six points of elastic fastening: two on forward longerons frames in podkapotny space; two under a body cabin; two in a back part of salon; and four points of semifixed fastening: in salon, around back nadkolesny niches). Elements of fastening of a body in salon are closed by caps.
Forward doors of a cabin consist of the external and internal panel, the hinged amplifier who is carrying out a role of a protective bar from side blow, and a connector. On the internal panel of a door the window regulator, the lock, the drive of opening of the lock closed by the formed upholstery are fixed. On a door are mounted motionless and lowering flew down. The side door and back doors consist of external and internal panels and amplifiers. Locks and their drives are in the doorway mounted. Consolidation of doorways is carried out by rubber sealants of the closed section.
The formed cabin partition upholstery consisting from top and two side upholsteries and upholstery are roofed outside by nonwoven fabric like "малифлис". Other upholsteries, the dashboard and floorings of footboards from polypropylene. Fastening of upholsteries is made by means of plastic percussion caps or the self-cut screws and flange nuts.
In a cabin seats are established: single for the driver and double for passengers. The seat of the driver has the adjustment mechanism on a pillow tilt angle, a tilt angle of a back and longitudinal movement. The seat of passengers of adjustments has no. All seats are equipped with seat belts; extreme places — humeral three-point with inertial coils, internal (central) — zone point-to-point.
Belts with inertial coils do not need adjustment, individual adjustment of its length is necessary for zone belts — the zone strap has to adjoin to hips densely. Change of length of a strap is carried out by the regulator.
At pollution of straps they need to be cleared soap solution. It is forbidden to iron straps the iron.
Belts are subject to obligatory replacement new if they underwent critical loading in the road accident or have attritions, gaps or other damages.
The Podkapotny space is formed by power details of a front, casings of headlights, racks of a radiator and longerons of a cabin. They are connected among themselves by spot welding and form rigid spatial power system. In podkapotny space on details of a body the accumulator, details and knots of electric equipment, cooling system of the engine, drive of a brake, coupling and an accelerator, a screen wiper etc. are fixed. On radiator racks through elastic elements the engine cooling system radiator is established. Radiator racks, for rigidity giving to the power scheme of plumage, by means of bolts are connected by the removable top panel of facing of a radiator. From above the podkapotny space is closed by the cowl consisting of internal and external panels. The angle of opening of a cowl to 74 °.
The body of a motor van of GAZ-2705 of "Kombi" unlike a body of GAZ-2705 is equipped:
- back row of passenger seats;
- the additional heater of a cabin located behind a seat of passengers of a forward row;

The body of buses is structurally similar to a motor van body with a triple cabin and has difference in a design of flooring of salon (depending on quantity of seats and planning), and also a design of a partition (low).
By buses of general purpose on 12 (13) places the partition is not established.
Buses are completed with two types of belts: three-point with inertial coils — at the driver, passengers of single and extreme places of seats and point-to-point zone — at passengers of average places of the seats and seats turned back (a compartment arrangement). Adjustment of belts is carried out according to specified for the GAZ car - 2705. By buses on 6 (7) — 8 (9) places the zone belts with the automatic coil of taking-up of a strap which are not demanding manual adjustment of its length can be established.
For providing a normal microclimate the additional heater established on a floor behind a passenger seat of a cabin or in a forward part of passenger salon is entered into system of heating. On a roof the ventilating and light hatch is installed.
