As shown in FIGS. 1 and 2, the inverse 2 fixed the floor 4 by Finterm & liaim with an O-ring. At least two holes of ixa'tiori. 22 are provided in the sole 20 to secure the traverse 2 garlic floor 4. Advantageously, these at least two fixing nuts. 22 malt dispi. at the transverse ends of the sole 20 and substantially to base plate 20, This dipusition allows an absorption of forces opnailsée under the constraint imposed by the impact of the baggage back of the positive & Mtenue. The notch 2 must be kept in place so that the soft spots 22 of the sole 20 are placed 2.5 e.i.:em ::ementement compared to the pianehe.r.4, in order not to eon. to be born of. problem of holding e ee. 's fastenings following the trays, the dimensions of the crossbar 2 around these fastener holes 22 being weak, tui maintain in position A front of the crossbar 2 is 4n: l1ement provided, a rang &. The seat is disposed ell before the cross 2, For reasons of holding the siep during shocks may be experienced by the vehicle, each armchair independent of this rang6t must be maintained in relation to the body, and in particular in a substantially vertical direction A To this end, a tab formed in the backrest of a rear seat is oriented towards floor 4 and requires receiving means 9 able to eeope.rer with a fixing means 10 integral with the floor 4. Fastening means 10 are the floor 4 and extends substantially vertically so that these means 10 allow- on the one hand the setting in position do traverses 2 relative to these A: rems fixed, and other pan, [e maintaining the position of the record 4, these fastening means take the 1'rrm of a pin 10 substantially vertical_ This pin IO has- an axis 1 1 of diamirrre déteminent at the top of which a T 12 is realized, the diameter of the tac. 12 Rani greater than the determined diameter of Faxe 1 T of the pin 10. The free extremity 13 and oppo4e to the t 12 of the pawn present_e appropriate means for fixing the pin 10 daiv, the floor 4, these means apprcipe. may elect a. As a csetnplc thread for screwing dd endte end. of the pin 10 in a bore of the floor 4. The axis] l has Len besides a groove 14 diarnere the diameter (.

A tita-e dVsemPle, Teprtsenté on [os figures, the indexago element is. Due roudette 1.6 -. t4me.e. The lower portion 18 of the washer has a diameter smaller than the diameter of the upper portion 17 of the washer.

  Positioning and maintaining in position of the cross member 2 relative to the floor 4 are then obtained by the cooperation of the washer 16 mentioned above and a fastening tab 24 made on the cross member 2. This bracket 24 extends longitudinally forwards the baggage retaining cross-member 2 so that it is oriented towards the seat row and towards the attachment means 10 of the arrangement according to the invention. The fastening tab 24 mainly comprises a notch 26 whose dimensions ro correspond to the diameter of the lower part 18 of the washer forming the indexing element 16. The complementary shapes of the lower part 18 of the washer and the notch 26 of the bracket 24 allow on the one hand the guide of the fastening tab 24 relative to the corresponding fixing pin 10. On the other hand, the presence of a shoulder 19, formed by the dimensional differences between the lower portion 18 and the upper portion 17 of the washer, allows the stop in longitudinal translation of the cross member 2. These means allow a setting effective position of the crossbar 2 with respect to the floor 4, this setting precise and repeatable position being essential for the fixing of the crossbar 2 on the floor 4 through the two fixing holes 22 located at the rear of the cross 2. Maintaining complementary position of this cross member 2 relative to the floor 4 is further obtained by adjusting the dimensions of the lower portion 18 of the washer 16 and the notch 25 of the bracket 24, and also thanks to the presence of the upper portion 17 of the washer 16 under which the fastening lug 24 is slid and which vertically locks in position this fastening tab 24. The fixing of the trave rse 2 on the floor 4 is provided at the front and the back of the cross 2 and is thus reinforced, the risk that the screws used at the rear of the cross 2 cede under the violence of a shock being thus discarded.

  A leg forming part of the back of a honeycomb seat is oiked towards the rear of the vehicle. In view of the cross member 2 of the baggage retainer 10 and the attachment means 10 of the arrangement according to the invention. This leg of the backrest has at least one first groove 9a substantially longitudinal and horizontal. The end of this first groove 9a oriented towards the back of the vtlnoule is free or, as shown in the figures, opens on a pamii equipped with a second The groove 9b is vertical so that these first and second grooves 9a, 9b are substantially perpendicular. In both cases, it is necessary to determine the dimensions of the grooves 9 and the fastening member. 10 are determined so that the fixing pin IO can slide in the preirdese groove 9a substantially horizontal.The first groove 9a cooper: thus with the fixing pin 10, and ea particular with the zone of the pin 1 () located under the tae 12, and located above the barley 14 of the pioa and the indexing natin 16 associated, 1.5 vertical movement of the leg of the backrest 8, and the associated movement of the seat, is blocked vt% s down by 1'Ilement indexing 16 and, from above by the head 12 of the pin 10: the arrangement of the fixafion according to the invention comprises the various elements referred to above, in order to optimize their interactions in the ull. Scheme of mit'ttagé these elements clam the 'vehicle can be following, Each fixing pin. is: everything first. mounted in the floor 4 of the vaieqle, has a determined place, while neither the. row of siege: arriee, nor traVONC 2: retention of hames are not undone in the as previously exemplary pawn 10 for. viase dariN Floor 4. te pawn 10 is onfbocé. in plarieher 4 until the party. lower 18de the rondelle 16 further in contact with the floor 4, the irférieui'o washer 18 pad ensures then: a sufficient espaec between plancha 4 and the upper part 17 of the mn delle 16 so that the paw ' fixing bracket 24 may extend the work 2 can be slid under the washer 16.
