     OBJECT OF THE INVENTION The present invention relates to a lumbar abatement system of 5 the front seats of a three-door vehicle, with which remarkable advantageous characteristics are achieved in relation to the current ball system pushed by radial appendix of the type that It is described in U 200002024, which is replaced by a similar system but with a cylinder, being aimed at achieving that the mechanism that retains the seat in its position of use is released when acting on a lever located in one of the upper angles of the backrest . When released, it can be folded down to allow people to enter the rear seats. When the seat regains its position of use, retention or interlocking automatically occurs. The improvement consists in that instead of the ball a cylinder is placed that is pushed by the radial appendix of the actuation lever, in addition the ramp through which the cylinder slides adjusts to its shape. The essence of the patent is that the cable does not have to be fixed to the actuation lever as is done in conventional designs, thus allowing assembly in 2 20 parts since the ramp-shaped part and the actuation lever allow the radial thrust of the end of the cable. The placement of the cylinder comes to solve low durability problem since the radial appendix was easily broken with the ball and thus the mechanism is more durable in addition to solving the mounting problem, in the seat since the cable assembly with the ramp and the cylinder, the foam and the fabric can be assembled before and after the assembly of the housing with the lever, thus improving the quality and ease of assembly of the fabric. The advantages of this invention are the following: It can be marketed as a durable product since with the previous system it did not pass the durability tests. DESCRIPTION5 Assembly is easier because the assembly with the housing and the actuating lever is assembled after the fabric. The mechanism can not only be used in the folding of seats but also in any gadget that serves to pull a lever push a cable that acts on a mechanism. The industrial application of this invention is within the seat folding systems, and more specifically lumbar abatement of the front seats. BACKGROUND OF THE INVENTION 10 Although no invention in force identical to that described has been found, we present below the documents found that reflect the state of the art related thereto. Thus document ES1047776U refers to a lumbar folding system of the front seats in three-door vehicles, 15 of the type that have a lever located in one of the upper angles of the backrest and that when actuated releases a seat retention mechanism by means of a drive cable, which includes a ramp-shaped piece that is fixed to the seat structure and in which a solidary ball is guided guided by the end of the drive cable, which is passed through a stepped hole provided in the body of this piece and in which the end of the sheath for said cable is housed, it being provided that the movement of the ball to release the seat is carried out by the direct thrust of a radial appendix of the actuation lever which rotates oscillatingly on an axis fixed to a housing 25 that also locks in the seat structure, after mounting the esp uma and fabric that define the seat upholstery. It is the utility model invention already in the public domain that caused the low durability of the system due to the ball that comes to solve the current patent by replacing the ball with a cylinder and the relevant modifications.Thus ES2313339T3 proposes a seating system, comprising: a seat frame comprising a pair of side rails and an upper beam; an energy transmission mechanism, comprising a pair of side bars, a pair of articulated connecting rods and a transverse bar 5 connected between said pair of side bars, in which said pair of side bars extend along said side rails from the pair of articulated connecting rods near said upper beam to said crossbar away from said upper beam; a headrest supported by said upper beam of said seat frame and connected 10 to said power transmission mechanism by said pair of articulated connecting rods; a lumbar support connected to said seat frame, said lumbar support comprising a front side, a rear side, an upper section, a lower section and a middle section between them, in which the periphery of said lumbar support is located inside with respect to said pair of side bars, said crossbar connecting said pair of side bars, and wherein said middle section is located near said crossbar, wherein said lumbar support has a set of operating positions and a set of impact positions; and an actuator operatively connected to said lumbar support, said actuator moving said lumbar support through said set of operating positions from a first position to a second position, in which in said set of operating positions it is not in contact with said power transmission mechanism and in which, in said set of impact positions, it is in contact with said 2S power transmission mechanism through said crossbar. In the aforementioned invention, the lumbar lever and cable chipping system proposed by the main invention is not mentioned. Document ES2256628T3 refers to a method for the control of a lumbar adjustment system of the seat of a vehicle, where the lumbar adjustment system shows -a first drive for an adjustment in a first direction of adjustment and -a second drive for an adjustment in a second adjustment direction, and the adjustment directions move away from each other, which, at the same time, drives a drive movementin the first direction of adjustment and in the second direction of adjustment. In the aforementioned invention, the lumbar adjustment drive mechanism is not contemplated, while in the main invention it focuses on the system that forms it, explaining its lever, cable and cylinder system in detail. ES1147634U refers to a self-adjusting seat device characterized in that it comprises a backrest formed by a back support plate, supported by a horizontal axis joint arranged in a support. It is a seating device that does not correspond to the front seats of the three-door vehicles, which are those that support the system described in the main invention. Conclusions: As can be seen from the research carried out, none of the documents found solves the problems raised as the proposed invention does. DESCRIPTION OF THE INVENTION 15 The lumbar folding system of the front seats of a three-door vehicle object of the present invention is constituted from a cylinder that is capable of ascending by an arched ramp configured for the stabilized effect in the housing provided in the frame or backrest structure. The rest of the support comprises the actuation lever of the mechanism, which is rotatable about an axis fixed to the housing and carrier of a double appendix with a circular groove where the cylinder fits and is capable of being pushed, forcing it to ascend through the ramp and in this movement the cable is pulled. In a different embodiment, the cylinder can have at least one cover or stopper elements in one of its bases to avoid displacements thereof in the axis direction.BRIEF DESCRIPTION OF THE DRAWINGS For a better understanding of the present description, some drawings that represent a preferred embodiment of the present invention are attached: Figure 1: Perspective view of the assembly that rotates separately to better visualize the ramp with the cylinder connected to the cable drive. Figure 2: Perspective cut of the system with the lever actuated and the cylinder with cable in extreme position. The numerical references that appear in these figures correspond to the following constituent elements of the invention: 1. Drive cable 2. Housing 3. Swivel lever 4. Lever shaft 15 5. Spring 6. Cylinder 7. Ramp 8. Appendix double 9. Circular groove 20 DESCRIPTION OF A PREFERRED EMBODIMENT A preferred embodiment of the lumbar folding system of the front seats of a three-door vehicle object of the present invention, with reference to the numerical references, can be based on the release of a mechanism of retention of the seat, through a cable of actuation (1) that relates the pieces mounted in the upper part of the backrest, with the interlocking latch located in the base of the seat, not represented in the figures and so that said seat can rotate around a front lower articulation axis. The rotating assembly comprises the housing (2) itself, the rotating lever (3) around an axis (4), and the spring (5) that assists thelever (3) to recover its retracted position. Said assembly is the one that moves the cylinder (6) that is capable of ascending through an arched ramp (7) configured for stabilized effect in the housing provided in the frame or backrest structure, by means of a double appendix (8) with 5 circular groove (9) of the lever (3), where the cylinder (6) fits.
