    [0004] OBJECT OF THE INVENTION
    [0005] The present invention refers to a retention system that comprises a seat belt that incorporates air chambers by means of which it is achieved that the fit on the user's body is not so tight, providing a high degree of comfort.
    [0007] It finds special application in the field of the industry of security elements in transport vehicles.
    [0009] TECHNICAL PROBLEM TO BE SOLVED AND BACKGROUND OF THE INVENTION
    [0010] In the current state of the art, belt restraint systems have evolved from an initial concept based simply on providing a stop in the movement of the user's body to providing different degrees of tension including stops that are activated when reaching a certain level. forward movement or even if there is a sudden movement.
    [0012] In either case, however, the initial tension of the belt, once it adjusts to the user's body, is continuous and with a greater tendency to be tight than to be loose, based on the fact that, in the event of a accident, the belt must be in contact with the body in order to stop the movement as soon as possible.
    [0014] However, this tension to which the seat belt submits the user's body causes discomfort in terms of lack of movement capacity of the user due to the pressure of the belt, the generation of heat due to the pressure generated by the belt and wrinkles in clothes among others.
    [0016] The present invention is focused on avoiding this series of drawbacks by incorporating a comfortable retention system formed by a seat belt that, while remaining in contact with the user's body, has a slack. whereby the pressure caused by the belt over the entire width of the belt on the body is avoided, thereby avoiding the discomfort described above. In addition, the system also modifies the fixed belt anchorage and the winding device to adapt to the new seat belt.
    [0018] DESCRIPTION OF THE INVENTION
    [0019] In order to achieve the objectives and avoid the aforementioned drawbacks, the present invention describes a comfortable restraint system that comprises a seat belt formed by a textile strap, a permanent anchoring device, for fixing one end of the belt, with means for the coupling of a fixing plate, a removable anchoring device to house a buckle that incorporates a pin that is crossed by the belt and a reel that houses the other end of the seat belt that is not in use .
    [0021] The novelty of the invention resides in that the seat belt comprises a chamber longitudinally attached to each side of the textile belt and pneumatically connected to a compression system located in the permanent anchoring device.
    [0023] For this, the permanent anchoring device incorporates connection ports and the chambers end at one end in adapters that fit into the connection ports, so that the chambers are pneumatically connected to the compression system.
    [0025] The restraint system is intended to be located in a vehicle that incorporates an electronic braking system governed by a control unit, in order to synchronize the restraint system with the electronic braking system, so that the restraint system is also regulated by the control unit. In this way, the air extraction flow from the chambers can be proportional to the intensity of braking.
    [0027] The comfortable restraint system preferably incorporates a depressurization mechanism by which the pressure of the belt on the wearer's body is reduced when unfolded, so that it separates from the wearer's body. The mechanism of Depressurization can be synchronized with the electronic braking system, so that the folding is proportional to the intensity of the braking and the depressurization mechanism does not have to return to its folded position to fully adjust the belt to the user's body, but only partially.
    [0029] The chambers are preferably configured in the form of highly flexible tubes made of polyurethane, for example, so that they quickly adapt to different shapes depending on whether they are inflated or deflated, and are attached to the textile belt by means of a coating that surrounds it. , preferably by sewing.

    [0053] DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION
    [0054] The present invention refers to a comfortable restraint system that comprises a seat belt (1) by means of which a non-contact zone is created between the user's body and the seat belt itself (1) that allows the continuous seat belt pressure (1) decrease.
    [0056] As shown in figure 1, the comfortable restraint system of the invention is configured by means of a seat belt (1), a permanent anchoring device (2), a removable anchoring device (3) and a reel ( 4) to collect the belt (1). Each of the components is described in detail below.
    [0058] Figure 3 represents the permanent anchoring device (2) of the restraint system and one of the ends of the seat belt (1), intended to be fixed in the permanent anchoring device (2). The other end of the belt (1) is fixed on the reel (4).
    [0060] As can be seen, the belt (1) is configured by a textile belt (6) and a chamber (5) longitudinally attached to each of the sides of the textile belt (6). Each of the chambers (5) ends in an adapter (9) and is attached to the textile tape (6), for example, by stitching a covering that surrounds it, leaving both chambers (5) fully integrated into the tape textile (6) and configuring a seat belt (1) without practical differences in flexibility or width with respect to the known ones. For its part, the textile tape (6) ends in an anchor plate (8).
    [0062] The permanent anchoring device (2) is firmly attached to the chassis of the vehicle. It incorporates an entrance for the introduction of the anchor plate (8) of the belt (1) and some connection ports (7) for coupling the adapters (9) and thus proceed to supply air to the chambers (5) of the belt (1).
    [0064] For its part, the interior of the permanent anchoring device (2) has not been represented, as it incorporates elements known from the state of the art. As essential elements, it incorporates a system for the mechanical fixing of the anchor plate (8) of the belt (1) and a compression system with a proportional valve, in charge of supplying and extracting air to the chambers (5).
    [0066] It must be taken into account that both the fixing of the anchor plate (8) to the permanent anchoring device (2) and the connection of the adapters (9) to the connection ports (7) are pre-established in the vehicle and are not elements accessible to the user. As for the anchor plate (8), it is solidly fixed inside the permanent anchor device (2), so it is not accessible to the user of a vehicle either. As for the adapters (9), they are solidly attached to both the chambers (5) and the connection ports (7), preferably by welding, so that they are not removably attached so that they are not manipulated by an user.
    [0068] Thus, by fixing the adapters (9) to the connection ports (7), the seat belt (1) is pneumatically connected to the permanent anchoring device (2) so that, through the compression system, it is possible to supply air to the chambers (5) or extract it at will, depending on the need.
    [0070] In figure 5 a cross section of the seat belt (1) can be seen, where it can be seen that, preferably, the chambers (5) are formed by hollow tubes of a highly flexible material, so that it can quickly absorb the dimensional changes due to air inlet or outlet. This material can be, for example, polyurethane.
    [0072] On the other hand, figure 4 shows the removable anchoring device (3) intended to receive the belt buckle (11) when the user puts on the belt (1). The buckle (11) is attached to a pin (10) that is crossed by the belt (1) to adjust to the size of the user intended to be retained. The pin (10) has dimensions superior to those of the state of the art, since it must be able to accommodate the chambers (5) of the belt (1) once they are inflated.
    [0074] The belt winder (4) has not been detailed in the figures either, as it is known in the state of the art. An end of the belt (1) is housed in it, as mentioned, being fixed to a shaft with rotation capacity where the belt is wound as it is housed inside the reel (4) to house the unused part . However, the reel (4) of the invention presents a difference from the known ones, in that it requires a system that allows the chambers (5) not to be inserted inflated into the reel (4). To do this, one of the devices that can be used to avoid this effect consists of rollers trapping the belt (1) on each side, so that the belt (1) is compressed between the rollers but can slide between them, preventing the passage of air through the chambers (5) beyond the location of the rollers.
    [0076] In addition, the system can incorporate an electromechanical depressurization mechanism (12) as shown in figure 2. This depressurization mechanism (12) is in charge of slightly separating the belt (1) from the user's body, so as to reduce pressure when the belt (1) does not need to be too tight. The depressurization mechanism (12) can be located near the reel (4), in an area of the seat near the reel (4) or in a place with which the objective of separating the belt (1) perpendicularly with relative to the user's body.
    [0078] The depressurization mechanism (12) can be constituted, for example, by a plate with the capacity to rotate around a joint, so that it can be folded and unfolded to fit or separate from the user's body. The plate incorporates a hole through which the belt (1) passes, so that, when unfolded, it also separates from the body of the belt user (1), causing a reduction in the pressure of the belt (1) on the user.
    [0080] Once the components of the comfortable restraint system of the invention have been described, it can be understood that, if the compression system blows air, the chambers (5) fill and cause the contact of the belt (1) with the user's body to be solely through of the outer zones of the belt (1), those occupied by the chambers (5), leaving the inner zone, occupied by the textile belt (6), free and providing a space without contact that reduces both the pressure on the user's body such as the generation of heat by contact, which results in greater comfort for the user.
    [0082] Regarding the operation of the restraint system, it must be said that it is run by the vehicle's control unit, which is in charge, through the use of sensors, of gathering the necessary information on the status and behavior of the vehicle.
    [0084] Through the information collected by the control unit, the activity of the brakes is promoted through an electronic braking system that incorporates the vehicle, always depending on the needs and in such a way that the percentage of braking that each receives is controlled. one of the vehicle's wheels. In this way, by operating the brake pedal of the vehicle, the intensity of the braking is controlled, making it more or less strong and based on the requirement that we are printing.
    [0086] In this way, the electronic braking system is synchronized with the restraint system of the invention, mainly through the compression system, which is responsible for the supply and extraction of air in the chambers (5) of the belt (1). This means that the air extraction flow from the chambers (5) is proportional to the intensity of the braking.
    [0088] Regarding the operation of the restraint system, both the belt (1) itself and the depressurization mechanism (12) are activated once the user of the vehicle puts on the belt (1), anchoring the buckle (11) in the device removable anchor (3) and starts the vehicle's engine, without the brake being activated. In this situation, the compression system is activated and, through the proportional valve, supplies air to the chambers (5), which are inflated to leave the belt (1) slightly slack with respect to the user's body and, in case if the depressurization mechanism (12) is incorporated, it is activated to provide a slight clearance with the user's body.
    [0090] On the contrary, when operating the brake pedal, the instructions sent to the compression system are in the sense of extracting the air from the chambers (5), so that the belt (1) adjusts immediately to the driver's body, understanding the system that is possible that a withholding will be necessary. In this case, the amount of air extracted can be variable, depending on the intensity of braking and proportional to it, as indicated.
    [0092] In the same way, the depressurization mechanism (12) is also synchronized with the electronic braking system so that, being in the deployed position, causing minimal pressure to the user's body, if the brake pedal is actuated, the depressurization mechanism (12) will fold to fit the belt to the user's body. This folding is preferably proportional to the intensity of braking.
    [0094] In addition, the restraint system can also be synchronized with adaptive cruise control, a method by which the speed at which you want to drive is regulated automatically and which, with the help of a radar system, also controls automatically, the driving distance with respect to the preceding vehicle, braking the vehicle if necessary to maintain said safety distance.
    [0096] Finally, it must be taken into account that the present invention should not be limited to the embodiment described here. Other configurations can be made by those skilled in the art in light of the present description. Accordingly, the scope of the invention is defined by the following claims.
