Abstract: The bodywork is accomplished with longitudinal members of the passenger compartment, and with upper crosspieces of the doors, which can be adapted to different models of automobiles by means of the use of supplementary section bars. This is done according to whether the bodywork is accomplished with doors of traditional type, or with doors of the so-said "enveloping" type. To the longitudinal member or to the structure of the crosspiece of the door at least a supplementary section bar is fastened. In particular, it is welded and shaped as to at least partially seal the longitudinal chamber defined between the longitudinal member and the structure of the crosspiece.

Abstract: At least one arm of suspension of each wheel of a vehicle axle is formed by at least two rods interconnected by telescopically-coupled members, which, on command, are capable of approaching or taking away the same rods to/from each other, in order to reduce or increase the length the same arm, so as to change the orientation of the rear wheels of the vehicle.

Abstract: A rearview mirror located in the interior of a motor vehicle passenger compartment, the support for the mirror being adjustable telescopically be the guided movement of an inner tube within an outer tube.

Abstract: The valve unit comprises non-return valves disposed within the intake duct and formed from longitudinal channels and flaps which engage these latter. The channels are provided with seal gaskets at their edges and are formed with their base walls shaped on their outer side in such a manner as to improve the valve reliability and life. The flaps comprise fixing tabs which are clamped between ledges and support surfaces of the superposed channels.

Abstract: In a multi-cylinder engine, equipped with at least two induction valves per cylinder, with one of said valves having a narrower induction and crossing stroke, and with another of said at least two valves having a wider induction and crossing stroke, and with a choke valve per each cylinder, the invention provides for a fuel injector to be installed substantially in correspondence of the induction valve having the narrower induction stroke and crossing.

Abstract: A silencer for the exhaust gas of motor vehicle internal combustion engines is proposed comprising an outer wall having in its upper part a deformable zone, preferably in the form of a transverse indentation, which provides preferential deformation under impact, and if a rear impact occurs prevents the silencer from rigidly striking the most inner structure of the vehicle floor and the fuel tank.

Abstract: The device comprises a control center arranged to control a first and second ignition coil and to operate the engine under double ignition during normal use and under single ignition during full induction; in this latter case, ignition by the spark plugs of a first set is alternated with ignition by the spark plugs of a second set, for predetermined numbers of engine cycles.

Abstract: A device for extracting to atmosphere the air from the interior of an automobile passenger compartment, comprising at least one air outlet aperture (12) provided in a wall (11) of the luggage compartment (10), and at least one non-return valve (14) engaged with said aperture (12), said valve (14) formed from a framework (16) comprising a grid (19) and a casing (18), and from a diaphragm (20) which is rotatably supported in the casing of the framework and which, when in the rest state, adheres to the grid (19). The framework (16) is mounted in the aperture (12) in the wall (11) of the luggage compartment (10), with the framework (18) and grid (19) disposed mainly within the interior of the luggage compartment (10).

Abstract: The device comprises an integrated unit formed by a container element having an opening for the filler, a door hinged onto the container element and subject to the action of an opening spring and an electrically actuatable lock for the door. The container element with the door and the lock mounted thereon are fastened as a single unit to the metal sheet of the bodywork.

Abstract: The proposed device comprises a cylinder rigid with a camshaft drive pulley, and a piston restrained to said cylinder and camshaft by helical groove connections and prismatic pair connections which, on command, allow said camshaft to undergo rotation relative to said pulley.

Abstract: A movable cover device for an automobile lock, comprising a plate supporting the lock operating actuator and fixed to a wall of an automobile compartment, and a cover pivoted on the plate, the device having in the cover an area substantially equal to that of the plate and is provided with a pivot substantially orthogonal to its wall and rotatably supported by a bush which is rigid with the plate and is also orthogonal to its wall, so that the walls of the plate and of the cover are in contact, at least when they are completely superposed.

Abstract: The object of the present invention is an electrical system for distributing electrical power to the user devices installed on board of a motor vehicle, and, in particular, the wiring of the electrical system located in the area of the dashboard, which is realized as a subsystem of multiplex type, comprising three electronic microprocessor control units connected by a communication bus constituted by a serial interconnection line for the transmission of data.

Abstract: An automobile light cluster, particularly a rear light cluster, formed from a central unit and two side units, where the central unit (12) comprises a base (16) having a structure in the form of cells aligned along a substantially horizontal axis (22), with at least one central cell (18) arranged to house at least one number plate light, and with at least one pair of flanking cells (19 and 20) forming the reversing and rear fog lights. The central unit (12) comprising for the base (16) a cover (15) formed from a single semitransparent sheet which is coupled with suitably colored inner walls (28), at least in correspondence with the central cell (18).

Abstract: A motor vehicle steering column comprises two telescopically interconnected portions, between which at least an elastic means is mounted which keeps conjugated walls of the said telescopic portions in reciprocal play-free contact in order to cancel out the rotational clearances, or play, between the said telescopic portions.
