Rotary front door locks
The teeth of the rotor 60 mounted on the central roller, when the door is closed, run into the teeth of the latch and turn the roller and the ratchet 54 installed on it, which is locked by the protrusion of the external drive lever 56 under the action of the spring 55. When the door is completely closed, the second tooth of the rotor 60 enters the second cavity latch, and the support at the end of the central roller (not shown in the figure) comes into contact with the latch nut 59 and, choosing a gap, prevents the door from moving vertically when the car is moving. At the same time, the support does not allow spontaneous opening of the door in the event of a collision or overturning of the car, when, due to deformation of the door or body, the lock rotor tends to disengage from the latch in the longitudinal direction of the car. The support, going beyond the walls of the latch, blocks the movement of the door. The door latch is secured with three bolts to the body pillar. Enlarged holes in the rack allow you to adjust the position of the latch in height and ensure its alignment with the lock, as well as in depth to ensure the full fit of the door to the seals and the location of the door flush with the outer surfaces of the body. The ratchet 54 has two teeth that provide preliminary and complete locking of the lock. This prevents spontaneous opening if the door is not fully closed. When the door is opened, the ratchet returns to its original position by spring 55.
Opening the door with the outer handle 50 is carried out through the leash 49, the force from the leash is transmitted through the rod 51 to the lever 56 of the external drive, which rotates and releases the ratchet. The door under the pressure of the compressed seal opens. The lower end of the rod 51 is locked with a screw on the external drive lever. From the passenger compartment, the door is opened by the handle 43 of the internal drive, mounted on a bracket, which is fixed with two screws on the inner panel of the door. By loosening the screws, you can move the bracket with the handle to the desired position. The force from the handle 43 is transmitted through the rod 42 to the lever 44 of the internal drive, which in turn presses the lever 56, releases the ratchet, and the door opens.
The lock can be blocked with button 48 to prevent access to the passenger compartment from the outside. When the button 48 is pressed with the door closed, the rod 47 rotates the lock lever 41 to the position where the groove in the lever 41 blocks the external drive lever 56. When the front door is open, the lock does not work and in order to avoid damage to the lock, it is forbidden to press the button. The lock button is installed on the threaded end of the rod 47 using a bracket. By moving the bracket to the next threads of the rod, the position of the button is adjusted. From the interior side, the button groove and the bracket inserted into it are closed with a cap. The lock buttons are located in the most convenient places for the driver near the central pillars.
The locked front door lock can be released by lifting the button 48, or pulling the handle 43, or the lock switch 52. When the switch key is turned, the leash of the latter acts through the rod 57 on the roller. The roller turns the lever 41, which with its groove blocks the lever 56 of the external drive when the lock is closed. When the key is turned in the opposite direction, the lever 41 releases the external drive lever and returns the button to the upper position. By pulling the handle 43 of the internal drive, the force is transmitted through the rod 42 to the levers 44 and 41, releasing the lock and returning the lock button to the upper position.
Rear door locks
The locks of the rear doors, unlike the front ones, can be blocked both with the doors closed and with the doors open (the button can be pressed with the door open and then closed). The lock can only be unlocked by lifting the lock button. This ensures the safety of transporting passengers in the rear seat.
The locks of the front and rear doors comply with safety requirements. The handles of the internal drive are located in such a way that if they are accidentally touched, it is impossible to open the doors. External handles do not have protruding parts. The design of the lock latches prevents spontaneous opening of the doors in the event of collisions and overturning of the car.
The limiter of opening of a door fixes its maximum opening preventing deformation of the external panel of a door. The limiter has a steel rod, the front end of which is connected with the help of a pin to the lugs of the plate welded to the body sidewall pillar. The rod passes through a plastic housing, fixed with two bolts to the door. There are two steel balls in the body, which are pressed against the rod by a spring. The free end of the rod is riveted, a steel washer is installed on it, in front of which there is a rubber buffer that limits the maximum opening angle of the door. There are two pairs of curly protrusions on the limiter rod, which, when the door is opened, push the balls apart and allow you to fix the full and intermediate position of the door opening.
Power windows
The front door window regulator is cable-operated, fastened with three nuts on the inner panel of the door. Four rollers 24 and 29, which covers the power window cable, are fixed on the brackets. The front lower roller 29 tensions the cable. To do this, pre-tighten the tension roller bolt with a nut and, with a blow through a special device, displace them along the groove on the inner door panel. After tightening, the bolt is finally tightened. The total length of the cable after drawing is 2930±5 mm. The cable is wound on a drum 31, the ring gear of which is engaged with the drive gear 32. In the support 33 of the drive roller 37, a spring brake is placed coaxially with the gear 32, which prevents the glass from spontaneously lowering. On the vertical sections of the cable with the help of two screws 27 and pressure plates 26, brackets 28 of the sliding glass are attached. The sliding window is placed in guide grooves bolted to the door panel.
The handle 40 of the power window is installed on the splined end of the drive shaft 37 and is fixed by facing 39 into the groove of the shaft. A plastic socket 38 is installed under the handle, which is pressed against the lining by the door upholstery. To remove the power window handle from the roller, you must first move the lining 39 along the handle and remove the handle with the lining.
Hood lock
The hood lock is attached with two nuts to the air intake box. The body of the lock is stamped from sheet steel. At the top, in the middle part, the body has a special cutout for fixing the latch pin welded to the hood and keeping the hood from transverse displacements. A hook and a hood ejector are installed on the body on the axles, which are pulled together by one spring.
When the hood is closed, the latch pin on the hood depresses the hook due to the oblique cut and sinks the ejector, stretching the spring. The hook under the action of the spring captures the pin. When acting on the handle, the wire rod, which is in a plastic sheath, pulls the hook and unlocks the lock. The ejector, under the action of a spring, lifts the hood above the surface of the body, making it possible to open it further by hand. The lock drive handle is mounted on a bracket under the instrument panel on the left side.
Adjustment of the hood lock is carried out by shifting the lock due to enlarged oval holes in the lock body.
Trunk lid lock
The trunk lid lock has a plastic housing attached with two nuts to a bracket on the inner panel of the lid. A rotor and a lever are installed in the housing on the axles, which are acted upon by a spring. The axes of the rotor and lever are riveted in the lock cover.
When closing the trunk lid, the rotor turns by pressing the latch. In this case, the lower arm of the lever under the action of the spring engages with the tooth of the rotor and fixes the closed position of the lock. The latch enters the groove of the body and fixes the trunk lid from vibrations and transverse displacements. The latch is welded to the plate, which is fastened with two nuts to the studs of the tailgate cross member.
To open the lock, the cylinder with the drive extension is turned with a key, the extension turns the lever by the upper arm and releases the rotor.
The normal operation of the lock can be adjusted by repositioning the lock or* the retainer due to the enlarged holes in the body and the retainer plate. Having outlined the contours of the lock body and the latch plate and loosening the fastening nuts, they are shifted in the right direction, after which the nuts are finally tightened.
Tailgate lock
The tailgate lock of the VAZ-2104 car consists of a body made of zinc alloy. In the case there is a hook with a spring; drive with a button and a larva locked with a key. The hook engages with the latch tooth, which is fixed on the cross member of the tailgate. To prevent vibration of the door, the lock has a special spike, which, when the door is closed, enters the conical socket on the top of the latch. The chrome-plated handle is also made of zinc alloy. The normal operation of the lock is regulated by the rearrangement of the lock or latch due to enlarged holes in the lock body and latch.
The sun visors are mounted above the windshield and can be rotated both horizontally and vertically to protect against direct and lateral sunlight. The visors have a wire frame and are lined with a film similar to that of the roof upholstery; foam pads are located between the film and the frame. On the sun visor, the driver has a pocket for documents.
Passenger handrails consist of a steel band on which a plastic facing of a shaped seat is put on. They are fixed on the top of the sidewall. The screws for fastening the handrails are closed with plastic decorative caps. There are plastic hooks for clothes on the rear handrails.
Seats
The front seats are separate with individual adjustment of the position of the seat and backrest. Each seat is installed on a slide, on which it moves forward and backward within 175 mm, and when unfolded into a sleeping position within 325 mm (total slide travel).
The seat slides consist of guides 17 and sliders 16 stamped from sheet steel. The sliders can move along the guides on two rollers 14 each. A limiter 12 is installed between the rollers, preventing the rollers from approaching each other. A comb lock is welded to the inner rail of each seat. The handle 19 for moving the seat is rigidly connected to the latch, which, under the action of a spring, enters one of the grooves of the latch comb. When the handle 19 is pressed down, the latch is released and the seat can be moved to the desired position. The seat slides are attached to brackets welded to the body floor. The seat back has coarse and fine tilt adjustment.
The backrest tilt adjustment mechanism is located on the outer side of the seat and consists of a screw with a handle 18 and a rod, a spring, a backrest amplifier 9 and a latch welded to the front of the pillow frame 21. A screw with a handle 18 is screwed into the end of the rod. There is a cylindrical groove on the threaded section of the screw, into which a cotter pin 15 is inserted through the groove. The cotter pin prevents the screw from completely turning out of the rod. On the screw between the handle and its threaded end there are annular grooves that engage with the teeth of the latch. The rear end of the rod is connected with a finger to the lower end of the amplifier 9, welded to the frame of the front seat back. The back of the seat is pivotally mounted on the frame 21 of the pillow and is fixed by means of a rod and a latch. If the handle 18 of the screw is lifted up (coarse backrest adjustment), the screw disengages from the lock; the thrust spring at the same time moves the screw with the thrust relative to the latch back, and the backrest forward. The driver or passenger can press the backrest back to the desired position. When turning the handle (fine adjustment) the screw is held in place by a latch, and the pull on the booster 9 moves the seatback to a comfortable position.
The frames of the cushion 21 and the back of the seat consist of thin stamped and wire metal frames. Wire springs 20, bent in the form of snakes, are attached to the framework of the frame 21 of the pillow using metal brackets. To avoid creaking, the brackets and the ends of the springs are covered with a layer of polyethylene. The back springs are connected to the frame with special plastic holders. The seat cushion and backrest frame are padded with polyurethane foam. On the cars of the first releases, the back padding was made from coconut palm linters. Seat upholstery in knitted imitation leather with a synthetic weldable wadding backing for crisp decorative patterns.
The front seats have 3 headrests adjustable in height and tilt. In the desired position, the head restraint is held by spring clips in guides 4 welded to the seat back frame. The headrest has a frame with two posts inserted into guides 4. The frame is padded with polyurethane foam and upholstered. By turning the headrest relative to the uprights, its position in terms of the angle of inclination changes.
The front seats can be folded down for relaxation. To do this, you need to remove the head restraints up from the guides 4, move the seat forward to failure (seat travel 325 mm) and, having raised the handle 18, disengage the screw from the latch, put the seatback in a horizontal position or comfortable for rest.
To fold the seat back, it is necessary, by raising the handle 18, to return the backrest to its original position and move the seat back, lower the handle 18 down and engage the screw with the lock.
The rear seat of the VAZ-2105 car consists of a separate back and cushion. The pillow with two holes 11 in the frame is mounted on spikes welded to the cross member of the body floor. The seatback in the upper part is fastened with two slats included in the brackets, which are welded to the tailgate shelf. In the lower part, the back is fastened with two tongues, which are welded to the wheel arches and bent onto the brackets of the lower corners of the back frame. Cushion and back frames are made of thin stamped and wire frames, to which springs are attached using metal brackets. Staples to prevent creaking of the springs are covered with a PVC film. The padding 7 of flexible polyurethane foam is installed on the pillow frame. A support 10 is placed under the padding 7 of the pillow. The upholstery of the seat is made of artificial leather on a knitted basis.
The rear seat of the VAZ-2104, unlike the VAZ-2105, can be folded to increase the area of the luggage compartment. The seat cushion and backrest are articulated on the body with hinges that allow the cushion to be raised vertically against the backs of the front seats, and the backrest to be placed in place of the cushion. The hinges are fastened with screws to the cross members of the body. The backrest in the unfolded position is fixed by two stops, which are included in the brackets on the bottom of the pillow. In the passenger version, the backrest is locked with two latches on the inner sidewalls of the body.
To fold the rear seat, raise the rear seat cushion to the upright position. If necessary, move the front seats forward. Press the locking levers and place the backrest in place of the cushion in such a way that the backrest stops fit into the brackets. To return the seat to its original position, it is necessary to raise the seatback, locking it in the normal position. Lower the pillow to a horizontal position.
Body sealing
Sealing is achieved by various rubber seals, sealing mastics, rubber plugs for technological holes and careful fitting of mating parts.
The air intake box is sealed against smoky air from the engine compartment entering the passenger compartment with a rubber seal installed on the upper flange of the box. The seal is fastened due to the elasticity of the metal perforated frame placed in the lower part of the seal.
The trunk lid in the opening is sealed with a seal made of sponge rubber and installed on the flanges of the drain grooves along the contour of the opening. The design of the seal is similar to that of the air inlet box.
Door opening seals are made of sponge rubber with a process to which a plastic edging with a metal frame is sewn, which ensures the seal is attached to the door opening flanges. Non-drying mastic 51-G-7 was applied under the sealant at the corners of the central pillars and door hinges.
The windshield and rear windows are sealed with rubber seals that do not require the use of sealing mastics. The lower seals of the sliding door windows are made of plastic, the profile of which ensures easy and reliable installation. To reduce friction, pile is glued to the seals of the sliding windows. When water seeps under the seal, it flows to the bottom of the door and then pours out through the drain holes. The mechanisms of the lock, power window and the inner surface of the upholstery of the doors are protected from water by a plastic film, which is attached to the door panel with spring holders.
The internal cavities of the racks, which have an outlet to the outside, are sealed from the ingress of cold air and dust with rubber seals, which, when the body is heated during the drying of the paintwork, increased in volume and filled the internal cavities of the racks. The internal cavities of the rear pillars are sealed with foam rubber and gaskets inserted inside the racks.
