     THERMO-EXPANDABLE DEVICE IN BODIES OF MOTOR VEHICLES FIELD OF THE INVENTION The present invention has as an object a thermo-expandable device 6, whose function is to create a wall or partition in a hollow space existing inside the body of a car body. vehicle, preventing air, dust, water, sound, etc., from being able to propagate through said holes, said device allowing to adapt to the assembly process of said bodies when plates must slide 12 over others until they reach their final assembly position , when the device recovers its working position, ready for its thermo-expansion and the creation of the hollow closing wall when the bodywork is introduced into the drying ovens. 18 BACKGROUND In the automobile industry it is known the need to close the cavities or gaps that remain inside the body once different laminar surfaces have been joined that make up what will be the exterior cover of the vehicle. This is because otherwise air, dust, water, and also noise or sound would spread through the body resulting in vibrations, noises, water inlets, etc., annoying and inadmissible in driving. In the known technique this type of partitions, whose object 30 is to cut the circulation of air, dust, water, noise, sound, etc. , in a hollow space, it is normally carried out by injecting in such gaps a material type DESCRIPTION6 rubber or fiber foam that fills and plugs. This is done once accessing the pouring an expandable. finished the assembly of the hollow by means of a conduit pre-established amount body, injector and foam It is a tedious process that can be perfected for example by means of the present invention which has as main objective as to provide a thermo-expandable device that can be installed in the initial stages of body formation so that when the 12 assembly of the assembled body is introduced into the furnaces, producing thermal expansion of the material, the closing wall of the body gaps is constructed automatically . Another of the objectives set forth by the present invention 18 is that the thermo-expandable device adapts to the pressure that the parts of the sheet in which by sliding of some sheets over others, until they reach, can reach in the assembly stage. Its final assembly position is temporarily compressed and crushed to the device, deforming it, but once the assembly of the bodywork is finished, the device can recover elastically and restore its initial configuration designed to close the existing gap. Another of the objectives envisaged by the present invention is that said devices incorporate stops or barriers, 30 when necessary, that prevent the expansion of unwanted areas of the device material.Another object of the invention is that anti metal device during the vehicle. collisions between plates or assembly process of the serve as chassis sheets of the 6 These and other advantages of the present invention will be more apparent throughout the description that follows. BRIEF DESCRIPTION OF THE INVENTION The present invention describes an expandable thermo-12 device in motor vehicle bodies, aimed at closing, cutting sections or filling the gaps that can be formed in the construction of vehicle bodies, for example between two of their formative sheets of the vehicle plate; said device is formed by an expandable thermo-18 base material that includes one or more flexible fingers, said finger / s projecting outwardly from said base material. The device can preferably incorporate a rigid plastic and rigid support, thermofix, not deformable by heat, of convenient shape and arrangement 24 in relation to its location in the body where it should be installed, which is support for said base material. This rigid support can incorporate containment stops, whose purpose is to block and limit the expansion of the base material of the device, due to heat, towards an unwanted hollow area of both the body and outside it.The present invention also includes the method of using said thermo-expandable device, according to which said device is previously installed in a sheet or in an open structure of the body, before finishing the assembly thereof by superposition 6 of the sheet antagonist, either directly or by sliding one sheet over another until it reaches its final position. The procedure includes the fact that once the vehicle plate has been created and the holes in the vehicle have been enabled, 12 the fingers of said device recover their original position, facilitating the subsequent creation of a partition that closes said hole when heating of the the body in drying ovens. The described procedure also foresees the existence of a support in said device for its fixation in the sheet of the vehicle, for example made of rigid thermofix plastic, which incorporates retaining or stop surfaces to the thermo-expansion of the base material towards places unwanted vehicle. 24 BRIEF EXPLANATION OF THE DRAWINGS For a better understanding of the invention, the present specification is accompanied by two sheets of drawings provided solely by way of illustration and not limiting the invention. Figure 1 is a perspective representation of a preferred embodiment of the present invention, within other possible ones, showing athermo-expandable device armed in a support structure, said device having flexible fingers. Figure 2 is a perspective representation of the embodiment of the previous figure, 6 individualizing the rigid material support. Figure 3 is a perspective representation of another possible embodiment of the present invention, in which a device with a base thermo-expandable material supported by a support structure 12 incorporating containment elements to the expansion of said expansion is shown. base material. Figure 4 shows a schematic representation, in cross-section, of the process of assembling two parts of the body of a vehicle, in which line 18 of dotting shows the part of the sheet that is assembled by sliding on another part sheet metal, this movement compressing the fingers of the device of the present invention. Figure 5 shows in cross section the body part of the previous figure already assembled, in which the flexible and elastic fingers previously compressed in the sheet assembly have recovered their original extended position. DETAILED EXPLANATION OF THE INVENTION The present invention consists of a thermo-expandable device in bodies of motor vehicles (1), used to close, cut sections or fill in thegaps inside the body of a vehicle, between its laminar surfaces (2). For example, in Pillar A, the construction of the vehicle body left a hollow space that must be closed to prevent air and noise transmission through the vehicle body. However, in this specific case, the welding order of the formative metal sheets of said body part makes said task difficult because a sheet moves over the base structure until the section is closed. 12 The present invention allows said section to be closed by incorporating the thermo-expandable device (1) to the bodywork at an initial stage of its construction, the section being still open and easily accessible for installing the device (1). The constructive arrangement 18 of the present invention is capable of overcoming, even, the mutual sliding of two parts of the forming sheet of said bodywork, as shown in Figures 4 and 5 that accompany the present specification. The device (1) is formed by a flexible base material (3) that is thermo-expandable and includes one or a plurality of fingers (4), as shown in the different embodiments of Figures 1 to 3. Said fingers (4) are areas of the base material (3) that project outwardly thereof. 30 This arrangement of the device (1), according to the present invention, incorporating fingers (4), gives the elasticityenough to support the assembly, welding or machining in the construction of the body. As Figure 4 shows, when one sheet (2) of the body moves over another until it reaches its final position, Figure 5, where it will finally be welded, the device 6 (1) is pinched and the fingers (4) compressed against the base material (3), but once the sheets (2) have reached their final and final position, leaving the hollow space between them, the fingers (4) thanks to their elasticity recover their extended position. 12 When in the manufacture of the body it is heated in the process furnaces thereof, the base material (3), and with it the fingers (4), will expand creating a partition between the sheets (2) of the body which will seal the section against the circulation of air, dust and noise. 18 It is also to be appreciated that the presence in the initial stages of the formation of the vehicle body provides another additional advantage to the present invention, which is that the device (1) avoids collisions between plates (2) during the Thanks to the fact that it acts as a shock absorber against the collision of two plates, avoiding not only noise but also the deterioration of said metal sheets in the assembly process. The device (1) can incorporate a support (5) of the rigid material, with the convenient shape in relation to its location in the body, made of any convenient material.6 12 18 In the preferred embodiments shown in the attached figures, this support is made of rigid plastic. In other envisaged embodiments, however, it is made of metal or other material, all within the present invention. Figure 1 shows a thermo-expandable device of this type. The plastic can conveniently be more or less rigid, being thermofixed, that is, supporting the heating in the furnace of processing of the body without deforming. Said support (5) can incorporate fixing means to the body of the vehicle, suitable to the area of the sheet (2), for example, where it must be installed. Said means within the known technique, being mechanical, adhesive fixings, etc. Finally, in another possible embodiment, as shown in Figure 3, said support (5) has containment surfaces (6), for example in the form of lateral fins, whose objective is to limit the expansion of the base material ( 3) by the effect of heat towards an unwanted area 24 or concentrate or direct to a specific area. On the other hand, the present invention includes the method of using the thermo-expanding device (1) in bodyworks of motor vehicles, according to which: Said device (1) is fixed and installed in a section of the bodywork before closing it. section superimposing and fixing the antagonist plate, including in the appropriate case the6 sliding said sheet over said section until reaching its final position, process in which compression of said fingers (4) and recovery of its original working position occurs, by elasticity, when said sheet reaches said final position, Expanding said base material (3) and with it said fingers (4) by the action of heat, creating a partition and closing said section against dust, water, air, sound and noise, etc. 12 The method includes fixing the device (1) to the body by means of a support (5), where said support incorporates means to limit the expansion of said base material (3) and / or of said fingers (4) towards unwanted areas of the body or in order to direct said expansion to a specific area. 18 24 It is understood that in the present case, how many details of finish or shape do not modify or alter the essence of the invention or its alternative embodiments, according to the claims made.
