    DESCRIPTION
    Clip for airbag.
    Field of the invention
    The present invention develops an airbag clip, of the type used in the automotive industry in the fixing of airbag devices, especially in side-curtain or curtain airbags, with the particularity that various constructive improvements have been made thereof. they allow, among other advantages, to increase the resistance of the clip to the extraction forces caused by the activation of the airbag mechanism.
    Background
    Airbags are a safety device increasingly used in the automotive industry and in combination with other safety elements, such as the safety belt, help to reduce fatal accidents in the event of collisions. The airbag deploys in fractions of a second, which represents a huge pull for its fasteners that suffer the consequences of this impact. In this way the industry is known for the tedious work that it represents for the operators to replace an air bag once it was activated.
    This task represents the disassembly of all the airbag fixings, the replacement of the airbag and the installation of a new one, placing all its fixings again.
    This is the reason that despite being the fastening elements of the airbag described in this invention mere fastening devices by fastening clips from elements to panels, the enormous stresses that they must support has determined specific configurations very elaborate face to face. favor the non-deterioration of the panel and the comfortable and easy installation of the airbag.
    The applicant of the present invention is also the patents EP 2 356 342 B1, EP 2 404 067 B1 and WO 2012/129233 A1 that develop some elements of such airbag clips, improving their effectiveness, and that with variations are widely used by the industry. Also said content is used in the clips of the present invention as prior art. The truth is that the use of such clips has shown that despite their advantages can still be improved, for example with the improvements included in the present invention.
    The patent DE 102010013612 A1 is a circular airbag clip that is constructed inverted to previous patents. Starting from one end of it, the furthest point in the insertion of the clip in the hole of the panel, a cylindrical box with two halves is formed, with the two parts of the half-shell facing each other, and from which the elements of fixing interiors and exteriors to the panel. The drawback of this arrangement is that its inverted arrangement facilitates disarming the clip against compression forces that tend to crush the clip and open it, separating its two halves.
    The patent W02012104250 A1 develops an airbag clip also in the line of the preceding patents, starting from a base on the outside of the clip, this is the part that is not inserted in the hole of the panel, said base generates by the extension of nail

    descending legs a box, formed by two facing half-shells, said half-shells presenting windows through which the wings created in the extension of the descending legs emerge, after coming out through said window, they form the work surfaces with the inner surface of the legs. panel.
    These surfaces that are working against the internal face of the panel must face the extractive forces of the clip in front of the activation of the airbag, have side walls of backrest and an inclined profile that works against the edge of the aforementioned window, offering a support . The outer part of the clip has a pronounced height and lacks adequate flexibility, it is quite rigid. The shape of the descending legs and the loop of them, essentially forming a semicircular segment, does not allow an adequate distribution of the forces in the piece. When facing the high forces of extraction due to the activation of the airbag, these forces, due to the constructive nature of the clip, do not tend to cohere the clip, but to destroy it, disengaging its parts that fail to act in all its resistant capacity.
    This type of clip is susceptible to be improved, mainly in what refers to its work performance, increasing the level of extraction forces that the clip can withstand the activation of the airbag and the distribution and direction of the forces that act on it
    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 develops improvements in the airbag clips, of the fixing clips of the airbag devices used in the automotive industry, especially the side or curtain airbags.
    The present improvements consist in a general reinforcement of the structure of the clip avoiding that when receiving the forces of use of the airbag, the clip is dismantled due to its geometry and prevents its structures from offering all their efficiency and performance.
    The clip forms a box that is a union of two half-surfaces and that at its joining ends presents linking means, both in the form of flanges and of the fitting elements of said flanges. This is the case of protrusions in said flanges that fit in openings present in the surface of the box.
    The descending wings of the clip present an inclination towards the center of the clip, they have a final loop that gives origin to the section of the descending wings that form the working surfaces against the internal face of the panel. These loops are in resistant contact, one against the other, acting against forces of both clip compression and extraction.
    The effort of the working surface of the clip against the internal face of the panel of installation of the same, is reinforced by lateral tabs in the window of the box that offer a support to said wings before forces of extraction of the clip.

    The wings of the clip have reinforcement protrusions and enlarged areas or enlarged surfaces, both to act against the inner face of the panel, as well as on the part of the wing that can rest against the edges of the clip case.
    The clip has flexible legs external to the surface of the installation panel that present the peculiarity that the opposing pairs are threaded, due to the existence of openings in one of said legs that the other crosses.
    These flexible legs are linked to the box of the clip by means of flexible joints by means of bends that present an elastic reserve.
    It must be taken into account that the clip of the invention has been made by means of the same sheet metal piece, its three-dimensional shape being obtained by bending and die-cutting. The clip is made of metal, heat treated steel, the piece being configured as high strength and incorporating the appropriate elasticity to respond to their workloads.
    In this way, all the intended objectives have been obtained, by providing an improved airbag clip which has high performance characteristics and which in particular maintains its cohesion when the airbag is triggered.

    Detailed explanation of the invention
    The present invention consists of an improved airbag clip, of the type of clips used in the fixing of airbags, for example side or curtain airbags, of which they are formed by a body from which flexible elements of support against the surface originate. of entrance, outside, of said clip in the fixing panel, as well as descending legs that generate different structures of said clip, as are lateral wings that present support surfaces against the inner face of said panel.

    fixing, so that said support surfaces and those provided by said flexible support elements are related to said fixing panel on both sides, in the manner of a sandwich, allowing the clip to be held in said panel.
    The clip (1), in fact, is formed with a single bent and die-cut laminar surface that realizes the three-dimensional body thereof. It is a metallic clip made of carbon steel heat treated to give it better resistant qualities.
    Airbag clips such as the one of the present invention are inserted in a hole made in a surface. This surface, formally, divides the clip into an upper, outer part, which is not inserted in said hole and a lower, inner part, which is introduced into the hole. The upper part of the clip corresponds to the outer part and the lower part of the clip corresponds to the inner part. In the same way, the ascending direction is built from the inner to the outer (lower-> upper) and the descending from the outer to the inner (upper-> lower) zone.
    A box (2) is formed by the union of two surfaces (3) with the approximate shape of a "Un, in cross section, are linked by one of its ends, said union being reinforced by tabs caused by the division of the zones. of union forming opposing surfaces (10) As can be seen in the attached figures the tabs (10) that are located inside the box (2) have nails (11) that have been configured to fit into openings provided in the box (two).
    The objective of this construction, which allows a greater solidity of the box, is to consolidate it preventing its disunion, making it difficult. As mentioned when citing the prior art, one of the known problems of the known art is that this type of boxes may not reach its full function, which is to support high compressive forces thereof, due to the fact that its structure it has been slightly disarmed, losing its resistant qualities and favoring its collapse.
    Figure 4 shows, in said front internal view of the piece, the crimp described above, between the nail (11) created in the inner flange (10) that passes through the hole in the outer surface of the box (2). Figure 3, which is a cross section to the previous one, also highlights said union.
    From this box (2) and away from the center of the clip (1), wings (5) extend internally with an inclination toward the axial axis of the clip center until reaching a loop (6) and extend in the opposite direction in some wings ascending (7). In the preferred construction of the invention and as shown in the graphs, the loops (6) of each wing (5) are in contact. This mutual contact is a resistant contact of one against another.
    This descending wing (5) has an enlarged surface (12), almost like a triangle, which allows its base to surpass the formative walls of the box (2). Obviously, this prevents the box (2) from being able to "descend" under pressure and surpass those stops represented by said enlarged surface (12).
    On the other hand, the ascending wings (7) are configured to emerge from the inner zone of the box (2) towards the outside thereof, through a space, hollow, opening or window made in its surface (3), creating a surface (8) that is approximately parallel to that of the installation panel and that is configured to

    act against it, in the known operation and previously described of said type of clips.
    This surface (8) is optimized for its function, being in fact broader than the own one of the ascending wing (7), in order to offer a greater contact surface between the clip and the lower surface of the installation panel.
    The sides of said window have flanges (16) that constitute a support for said surfaces (8) of the box (2) against the inner face of the panel in response to forces tending to the extraction of the clip (1).
    The ascending wings (7) have a continuation, towards the upper part of the clip by bending at an angle greater than 90 ° forming an upper convergence, without necessary contact, with the respective wing of the other side of the clip. This construction allows the unclamping of said clip (1), for its removal, because the ends of said upward wings are configured as tabs (9) that allow to retract, when compressed towards the center of the clip, the surfaces (8) with respect to the edges of the hole in the panel, which allows the extraction of the clip (1).
    The working assembly of said wings (5 and 7) is optimized to offer improved structural resistances, incorporating reinforcement protuberances (15) on its surface.
    At this point, special attention should be paid to the specific geometry of the wings (5 and 7) and how they work resisting the stresses that the clip (1) must withstand. Mainly forces in ascending and / or descending direction. The design of these wings allows a dynamics of forces in which the tensions experienced by the clip (1) require the participation of all its elements that contribute positively, in this way, to increase its efficiency. When, for example, the surfaces (8) of the ascending wings (7) are compressed against the internal face of the installation panel, both the resistive contact of the loops (6) and the descending wings (5) work against this tension. ) and its reinforcements (15) in tension against the edges of the windows of said box (2) and the flanges (16); the reinforced strength of the same box (2) helps to cope with the aforementioned received voltage. The enlarged surface (12) of said descending wings (5) abutting against the box (2) prevents collapse of the wings (5).
    Analogously, the elements of the clip (1), characteristic of the present invention are configured to offer an improved structural resistance of the clip against compressive forces thereof.
    As seen in the figures accompanying the present invention, said box (2) at the top, in the direction of its position in relation to the hole of the installation panel, has two pairs of flexible legs (4) connected to it. they crisscross, two from each side. One of said legs (4) has an opening (13) that allows the other leg, the antagonist, to threaded, through it, said opening. These legs (4) are linked by an elastic fold (14) to the box (2).
    As can be seen from said construction, this gives a convenient strength and flexibility of the piece against compressive forces of the clip (1). The crossing of the legs (4) gives some lateral support, avoiding the misalignment of the legs. This effect,
    the prevention of mutual misalignment of the legs (4) is ensured with the openings (13) and the threading of the opposing leg in said opening.
    The number, the height and the flexed shape with an elastic zigzag structure of said 5 legs (4) ensure a good behavior of the device against the received compression loads.
    The clip of the invention can be subjected to an anticorrosive treatment and / or receive a suitable coating in order to improve its useful life and wear against dust, moisture or other elements that could attack the clip.
    It is understood that in the present case can be variable how many details of finishing and form do not modify the essence of the invention.
