Par conséquent, les présents Iodes de réalisation doivent être considérés à titre d'illustration, mais peuvent être modifiés dans le domaine défini par la portée des revendications jointes, et n ne doit pas être limitée aux détails donnés ci-dessus. Currently, the vehicle element attachments as they are today do not make it possible to comply with them. They are usually too rigid. Moreover, there are no elements of the engine compartment in the regulatory shock zone under the vehicle hood. The object of the present invention is to meet these requirements of 20 C 1tes by proposing an element fixing device which allows the element supported by this attachment to be removed from the regulatory shock zone in such a way that irreversible 1 (shock, this fix) is gone). suitably adapted to light elements such as ducts, resonators, scoops, and air boxes of engine air mission systems. This goal eE by a fixing device making the connection, by a beam, between the element to be supported and the part of the vehicle supporting the element, characterized in that the beam corn - in a zor medi (- (3 to support and the part of the vehicle stile wind, a pendicular to the axis of the beam, this ° i consists of a groove ending, in order, a groove of larger size and a vacuum, the dimensions of the grooves and the vacuum being adeptées so that the beam resists the mounting force according to a: c parallel to the axis of the beam and deforms f) n reversible or irn a-sible in the direction the impact force perforce at the axis of the beam so as to fade from the shock zone reg the beam is eudée or end, to the suppor ié ei element having, opposite, fixing system to the part of the vehicle supporting the é: it According to other particularity, the opening of the bleeding is made This according to L 1 other particu, the length of the groove is equal to the width of the beam along an axis perpendicular to the axis of the beam. According to another feature, the length ee is less than 15 the width of the beam along a perimeter axis Joaaire xe of the beam, so as to form bridges along the axis of the beam. In another feature, the widths and depths of the grooves of the groove are defined so that ation resists assembly of the element on the vehicle as well as the current seilieilaLlons suffered by the supported element. According to another pa.i 3r. the dimension between the lowest positic of the groove and the surface of the beam opposite to the axis of the axis parallel to the direction of the ulloc force is determined so that the device It is also possible for the supported element to be removed from the regulation shock zone in the event of an impact and, in another feature, the denier zone (FIG. It is maintained by the fastening device in the direction of the impact force and is free to allow the element to penetrate into the shock. In another feature, the fastening element to the supported element is a glue or In another embodiment, the fastening device for the part of the element is a clip with an abutment. Another special feature is that the fastening systems can be reversed. other features and advantages of this invention The following description will be made more clearly apparent with reference to the accompanying drawings, in which: FIG. 1 is a diagrammatic view of the fixing device according to the embodiment; Figure 1 shows a side view of the fastening device according to an idea of the figure showing a side view of the region of the fastener having the groove in a mode of reflection; Figure 4 shows a view of a side view. i isposil fixation ls comprising the supported element and the zone behind: d ~ r .sit The invention provides a 1 fixing device () making the link by a tre (1) between the element (2) suppo . `er and the part of the vehicle (3) to support the element with reference to Figure 1. Referring to Figure 2, the r ~ fixation device () supports the element (2) in such a way that the beam (1) rf the training effort (7) in a direction parallel to the axis (12) of the pc * e (1) and s. reversibly or irreversibly in the direction of the perpendicular impact force axis (12) of the pou The fixing device (0) comprises a groove (11) in an intermedia zone, (5) between the element and the vehicle part (3) supporting the element (2) perpendicular to the axis (12) of the beam (1). 3, the groove (11) of depth t is a groove of width d1 and depth p1 ending, in order, by a groove of depth p2 and = ur d2, d2 being greater than d1, and a dime gap d3, d1, d2, p1 and p2 being defined so that the fixing device n '. the mounting of the element (2) on the worm a = ue (3) and the common stresses experienced by the element (2) supporta. According to this embodiment, the dimension e, between the lowest one of the first one; ) a (11) and the surface of the p (1) opposite the opening of the groove (11) along an axis parallel to 1 on one of the shock force (6), is de finie for the device of fixa :; it is resistant to the DC forces, suffered by the element (2) supported and t '' '(-me re rrevel `` ale or irreversible for the element (2) sup erases ze regulatory shock in case of By reference to FIG. 4, the supported element (2) of height h is outside a height z1 of the boundary (10) of the zone of elemental area. the direction of the free impact force of a height z2 at least equal to h so that the supported element (2) can penetrate completely into the zone. As is apparent from the present invention, the embodiments of the present invention can be considered as present in many specific embodiments without departing from the scope of the claimed concept. illustration, but may be modified in the field defined by the scope of the attached claims, and n must not be limited to they given above.
