Finally, a method is described for ergonomic analysis using the system in question.

In a motor-vehicle, the windshield and/or the rear window and/or one or more side windows or a roof window each comprise a multi-layer glass plate (3), including two glass layers (3A, 3B) with a film (5) of synthetic material interposed therebetween. At least along one part of the perimeter of the multi-layer glass plate (3), the peripheral surface (32) of the plate has a portion which is permanently exposed to air and atmospheric agents. In order to prevent the formation of air bubbles in the contact aria between the film of synthetic material and the plate layers, said peripheral surface (32) of the plate is covered by a paint protective coating (4).

A motor-vehicle lattice frame (T) is described here that includes a plurality of structural nodes (N1, N2) each having a central body (1) and at least one hollow arm (2, 3, 4, 30) protruding from the central body (1). The lattice frame (T) also includes a plurality of beam elements (5, 6, 11, 27) connected to each other by means of the hollow protruding arms (2, 3, 4, 30). The structural nodes (N1, N2) are made by an additive manufacturing technique and at least one arm (2, 3, 4, 30) of one of the nodes (N1, N2) has an end portion opposite to said central body (1) having a channel shape (C) with an open cavity both at a front end (12) of the arm (2, 3, 4, 30) and along one side (13) of the arm (2, 3, 4, 30).

A joint between at least one element of metal material (1) and at least one element of plastic material (2) is obtained by pressing these elements in contact against each other, with a simultaneous application of heat. The method further comprises the step of applying a cladding (C) of metal material and/or of plastic material above the joint by additive manufacturing technology.

A heat exchanger, in particular a radiator for a cooling system of a motor-vehicle engine, comprises a plurality of tubes (8). The plurality of all the tubes (8) is defined by a single body in one piece, made by additive manufacturing technology. The tubes (8) each extend along a tortuous path, so as to increase the surface for heat exchange, without requiring the provision of auxiliary fins within the spaces between the tubes. The above-mentioned tubes (8) may have a sinusoidal configuration and may be aligned in rows and columns, according to a matrix arrangement, or they can define a three-dimensional net arrangement, with the tubes which communicate, or do not communicate, with each other, or they can define a tangled chaotic arrangement, with the tubes being in communication, or not in communication, with each other. The body of the heat exchanger may have a non-conventional configuration, such as an elongated and curved shape, so that it can be adapted to the shape of the front wall of a motor-vehicle, adjacent to which the heat exchanger is to be mounted.

A light duty vehicle comprises a vehicle frame (3), including a pair of longitudinal beams (4) connected to each other by a plurality of cross-members (5) and a cabin frame (2), comprising a pair of longitudinal beams (7) rigidly connected to the front ends of the longitudinal beams (4) of the vehicle frame (3). The vehicle further comprises a supporting structure (8) for auxiliary units (9), such as gaseous fuel tanks or electric batteries, this supporting structure being carried by the vehicle frame (3). The supporting structure (8) for the auxiliary units (9) comprises an auxiliary frame (80) which extends between the longitudinal beams (4) of the vehicle frame (3) and has at least two connection plates (P) arranged in vertical planes parallel to the longitudinal direction of the vehicle frame (3) and which are in contact with the mutually facing inner lateral walls (4D) of the longitudinal beams (4) of the vehicle frame (3) and are rigidly connected to these longitudinal beams (4). The auxiliary frame (80) fulfills a structural function equivalent to the structural function of one or more cross-members (5) at an area of the vehicle frame (3) where the cross-members (5) are omitted.

A motor-vehicle is equipped with an auxiliary refrigeration circuit (F') with an electrically-operated compressor (C') of reduced size and power compared to the compressor (C) of the main refrigeration circuit (F). An air guide duct (2) which drives a flow of air towards the passenger compartment of the motor-vehicle includes an auxiliary inlet portion (201) - arranged upstream of the main portion (200) - which contains the evaporator (E') of the auxiliary refrigeration circuit. The vehicle comprises one or more electronic control circuits programmed to activate a refrigeration mode and a heating mode of the passenger compartment when the motor-vehicle is parked with the engine off, even with the driver outside the vehicle. In this operating mode, the auxiliary circuit is active and the flow of air towards the passenger compartment is cooled by passing through the evaporator (E') of the auxiliary refrigeration circuit (F'), or is heated by using the heat generated by the condenser (D') of the auxiliary refrigeration circuit. The electronic control circuits are programmed to also activate a ventilation mode of the passenger compartment, which comprises controlling at least partial opening of one or more windows of the motor-vehicle and the opening of one or more communication valves (101) of the passenger compartment with the external environment, to generate the natural circulation of air from the bottom upwards through the passenger compartment. The cooling, heating and ventilation modes can be controlled by the user by means of an electronic interface device such as a smart-phone, a tablet or the like.

Motor-vehicle seat, in particular a rear motor-vehicle seat, comprising a backrest frame (5) including an upper cross-member (5A), and a headrest (HR) connected to the upper cross-member (5A) and tiltable between an upright operative position and an inoperative position rotated forwardly relative to the operative position. The headrest (HR) is rotatably mounted on the upper cross-member (5A) of the backrest frame (5), whereby it is adapted to tilt between its operative and inoperative positions around a transversal axis (50) which is vertically located substantially at the same height of the cross-member (5A).
