Abstract: A seat backrest for a motor vehicle has a structure, which supports a padding covered by a cover; the structure has a rear plate provided with a coupling portion, to which an end of the cover is fixed along a peripheral edge of the plate itself; the plate is fixed to a front frame by means of a snap-on connecting device having a plurality of deformable appendages, which are carried by the plate in positions that are spaced apart from one another; the appendages are part of respective brackets, which are fixed to the plate and have respective stiffening portions, which are arranged at the coupling portion.

Abstract: A motor vehicle cup holder with a support made of a rigid material and having a receptacle, which extends along a vertical axis and is radially delimited by a side surface, having at least one retaining seat. The cup holder has a lining device, separate from the support and having a liner, which lines at least part of the side surface and defines a seat for housing a container. The lining device has an elastically deformable inner protuberance to grip the container and an outer protuberance to engage the retaining seat of the support and is elastically deformable to enable disengagement of this outer protuberance.

Abstract: A vehicle is provided with a luggage compartment that houses an additional support unit having a loading floor, height-adjustable between a lowered position and at least one raised position; when in the raised position, the loading floor is supported, but can rotate upwards about a horizontal axis of rotation; the unit has two levers, which are hinged to a fixed structure about a first horizontal axis and to the loading floor about a second horizontal axis, which is set apart from the first horizontal axis by a variable distance.

Abstract: The spectrometer comprises at least a first optical path for a beam of electromagnetic radiation, along which the following are set: a beam-entry slit (1) for an incoming beam; a collimator (5) comprising a convergent spherical mirror for collimation of the incoming beam; a first dispersor (9) for dispersion of the beam into its chromatic components; a first focusing system (19); and a first detector (21) which receives the beam dispersed and focused by said first focusing system. Set along the first optical path there is set at least one first aspherical corrector element (7; 17) comprising an aspherical mirror for correction of spherical aberration.
