Abstract: A battery pack for the propulsion of electric road, boat or aircraft vehicles, includes a plurality of battery modules. The battery cells of the pack are arranged with their planes oriented horizontally, according to a “lasagna” configuration, over a lower tray. Superimposed layers of cells are provided, separated by aluminum sheets, which hinder the propagation of heat and flame. Between the cells there are tubes of a circuit for a coolant or alternatively a cooling panel is provided under the cell layers. The cells have one side glued to an adjacent aluminum sheet and the opposite side also glued to an adjacent aluminum sheet or covered by a pad of elastically deformable material. The terminals of some cells side-by-side are connected to each other by means of bars held in position by clamps, with an arrangement such as to simplify the assembly procedure.

Abstract: A motor-vehicle door comprises a structure including an inner panel (3), a carrier (5) fixed to the inner panel (3), for supporting a plurality of auxiliary members of the door, and a trimming panel (6, 7) which covers the carrier (5) and the inner panel (3) on the inner side of the door. The carrier (5) is made of fibre-reinforced synthetic material and it is rigidly connected to the inner panel (3) and it is configured to also serve as a structural reinforcement for said inner panel. The carrier (5) also has at least one portion (50, 52) exposed to view, not covered by said trimming panel (6, 7) and having a structure and a configuration such to directly serve the function of trimming panel at the exposed portions thereof. In a variant, the inner panel is constituted by a quadrangular framework constituted by one or more C-section elements defining an upper crosspiece, a lower crosspiece and two uprights which connect the ends of said crosspieces to each other.

Abstract: A locking device for preventing the rotation and/or the axial movement of a pin includes a coil spring wound around at least a portion of the pin and having one end rigidly connected to a support structure. In its undeformed condition, the spring has an internal diameter smaller than the diameter of the pin, whereby in its resting condition the spring is tightened around the pin to prevent a rotation thereof at least in a direction or an axial movement in any direction. The device includes shape memory means for causing the unwinding of the turns of the spring for the purpose of temporarily releasing the pin.

Abstract: A system for distributing air in the passenger compartment of a vehicle, e.g. of a motor vehicle, comprises at least one outlet for the outflow of air in the passenger compartment which can be activated placing a hand at a short distance therefrom without touching it.

Abstract: A system for air distribution in the passenger compartment of a vehicle, for example a motor vehicle, includes at least one outlet for outflow of air into the passenger compartment, which can be activated by putting one's hand at a short distance therefrom without touching it. Associated to the air outlet is an optical sensor, which is set at distance from the air outlet and is optically connected to a window adjacent to the air outlet.

Abstract: A sunshade device comprises a sunshade in the form of a roller blind forming part of a roller-blind device, comprising a supporting structure, a shaft for rolling of the sunshade blind, mounted so that it can rotate on the aforesaid supporting structure, and a shape-memory actuator device for causing displacement of the blind from the rolled-up condition to the distended condition.
