## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application is the 35 U.S.C. §371 national stage of PCT Application No. PCT/EP2013/057661, filed Apr. 12, 2013, which is herein incorporated by reference in its entirety and which also claims priority to, and the benefit of, Italian Patent Application MI20120000151, filed Apr. 13, 2012, which is herein incorporated by reference in its entirety.
The present invention relates in general to an assembly composed of a saddle and a saddle compartment for motorcycles and, more in particular, to an assisted opening system of the saddle in relation to the relative saddle compartment.
On some types of motorcycle, in particular but not exclusively, mopeds with two or more wheels, it is known of to apply saddles which can be opened to permit access to a saddle compartment. Such saddle compartment is normally utilisable as a compartment for holding helmets and/or as a luggage container and may also provide access to some technical and functional components of the motorcycle, such as for example the fuel tank or battery.
The saddle is usually connected to the relative saddle compartment by hinge means which enable it to pass from a closed position, in which the saddle is positioned substantially horizontally above the saddle compartment and permits the rider and any passenger to sit on the motorcycle, and an open position, in which the saddle is positioned in a substantially vertical position and permits access to the saddle compartment. Closing means may then be provided, normally consisting of a lock with key, to prevent the unauthorised opening of the saddle and thus protect the contents of the saddle compartment.
In some embodiments, the hinge means which connect the saddle to the relative saddle compartment act in conjunction with a gas spring which permits a particularly smooth opening of said saddle. The gas spring in addition makes it possible to safely keep the saddle open, and makes such saddle close silently and gently without any noisy impact.
In the embodiments of the known type the gas spring is visibly positioned inside the saddle compartment, thereby subtracting a part of the useful space available in such saddle compartment. Such visible arrangement of the gas spring may in addition prove inconvenient to the user, who may accidentally interfere with the proper functioning thereof.
The general purpose of the present invention is therefore to make an assembly composed of a saddle and of a saddle compartment for motorcycles which is able to resolve the drawbacks of the prior art mentioned above in an extremely simple, economical and particularly functional manner.
In detail, it is a purpose of the present invention to make an assembly composed of a saddle and of a saddle compartment for motorcycles which makes it possible to fully use the space available in said saddle compartment.
Another purpose of the invention is to make an assembly composed of a saddle and of a saddle compartment for motorcycles which is able to guarantee greater stability of the saddle in its open position.
A further purpose of the invention is to make an assembly composed of a saddle and of a saddle compartment for motorcycles in which the gas spring is present but not visible by the user.
These purposes of the present invention are achieved by making an assembly composed of a saddle and a saddle compartment for motorcycles as described in claim 1.
Further characteristics of the invention can be seen from the dependent claims, which form an integral part of this description.



The characteristics and advantages of an assembly composed of a saddle and of a saddle compartment according to the present invention will be more clearly evident from the description below, made by way of a non-limiting example with reference to the appended drawings, wherein:
FIG. 1 is a side elevation view of the assembly composed of a saddle and of a saddle compartment according to the invention, in which the saddle is shown in the open position;
FIG. 2 is a perspective view of the assembly composed of a saddle and of a saddle compartment according to the invention, in which the saddle is shown in the open position;
FIG. 3 is a detailed view of the components carrying out the opening and closing of the saddle; and
FIG. 4 is another perspective view of the assembly composed of a saddle and of a saddle compartment according to the invention, in which the components carrying out the opening and closing of the saddle are shown.



With reference to the figures, a preferred embodiment of the assembly composed of a saddle and of a saddle compartment for motorcycles according to the invention is shown. The saddle and relative saddle compartment are respectively denoted by reference numerals 10 and 12.
The saddle 10 comprises, in a manner in itself known, an upper padded portion (not shown), which constitutes the seat for the rider and/or passenger of the motorcycle, and a substantially rigid bottom portion 14 operatively connected to the relative saddle compartment 12 by hinge means 16. In turn the saddle compartment 12 is made integral with a fixed portion (frame or chassis) of the motorcycle by attachment means of the known type.
The hinge means 16 enable the saddle 10 to pass from a closed position, in which the saddle 10 is positioned substantially horizontally above the saddle compartment 12 and permits the rider and any passenger of the motorcycle to sit on it, and an open position, obviously obtained when the motorcycle is at a standstill, in which said saddle 10 is positioned in a substantially vertical position and permits access to the saddle compartment 12. Closing means (not shown) may then be provided to prevent the unauthorised opening of the saddle 10 and thus protect the contents of the saddle compartment 12. For example, such closing means may consist of a lock with key.
The saddle 10 is of the type with an assisted opening system and at least one gas spring 18 is thus provided positioned between the saddle 10 and relative saddle compartment 12. More specifically, according to the embodiment shown in the figures, the gas spring 18 is attached at the bottom to a fixed portion of the motorcycle and is operatively connected, at its upper end, to the saddle 10 by means of interposed articulated connection means which permit said saddle 10 to maintain a stable open position. As shown in FIG. 3, the gas spring 18 may be attached to a fixed portion of the motor cycle by means of an interposed shaped coupling element 26.
In detail, the aforementioned articulated connection means comprise a plate 20, attached to the saddle 10 and to the hinge means 16, and a curved arm 22, fixed at the top to such plate 20 and at the bottom hinged to the upper end of the gas spring 18. The curvature radius of the curved arm 22 is calculated so as to firmly maintain the saddle 10 in the open position shown in FIGS. 1, 2 and 4.
The gas spring 18 is guided, in its extension and contraction movements corresponding respectively to the opening and closing movements of the saddle 10 in relation to the respective saddle compartment 12, inside a casing 24 made in the side wall of such saddle compartment 12. This way the gas spring 18 always remains hidden during the opening of the saddle 10 and the user sees only the curved arm 22 which, directly attached to the plate 20 in turn attached to the saddle 10 and to the hinge means 16, makes the saddle 10 more stable in its open position. The casing 24 may be made in one piece with the side wall of the saddle compartment 12, or may be attached to such side wall of the saddle compartment 12 by means of generic attachment means, reversible or otherwise.
It has thus been seen that the assembly composed of a saddle and of a saddle compartment for motorcycles according to the invention achieves the purposes specified earlier.
The assembly composed of a saddle and of a saddle compartment for motorcycles thus conceived, is in any case susceptible to numerous modifications and variations, all falling within the same inventive concept; moreover, all the parts may be replaced with technically equivalent elements. In practice, the materials used, as indeed the shapes and dimensions may be varied as needed according to technical requirements.
The sphere of the invention is thus defined by the appended claims.
