Definitions

  • the present invention relates to a folding backrest of a rear seat of a motor vehicle according to the preamble of claim 1.
  • Such backrests are hinged to the seat part to provide a through-loading possibility between the trunk and the passenger compartment.
  • they In addition to a reliable anchoring to the body, they must have sufficient rigidity and rigidity to ensure that they z. B. act as a barrier in a rear-end collision and prevent cargo from entering the passenger compartment.
  • a generic backrest which has a manufactured by extrusion, one-piece base element, which consists of a base plate and two extending in the extrusion direction extrusion profiles.
  • base element which consists of a base plate and two extending in the extrusion direction extrusion profiles.
  • cross beams are preferably inserted between the two extrusion profiles extending in the extrusion direction, preferably also in the form of extrusion profiles, and connected to the base plate.
  • Object of the present invention is to provide a further generic backrest available, which is easy to build, easy to assemble, requires relatively low tooling costs and allows flexible construction.
  • the supporting structure of a hinged backrest therefore consists of four profile parts made of a light metal.
  • Each of these profile parts has a hollow frame area and a plate area. They are mitred from extruded profiles in such a way that when welded together they form the base plate with circumferential hollow frame. Due to the production of a light metal such a backrest undoubtedly builds easily. Furthermore, it is easy to assemble by the four profile parts are joined together by welding. Since the tooling costs are comparatively low, - - can be responded to the desired design changes by cost-effective production of new tools.
  • a further reduction of the tool cost can be achieved, in particular, by virtue of the fact that the profile parts lying opposite each other in the welded-together state are cut out of an extruded profile. As a result, only two extrusion tools are required, being cut from the profiles thus produced for the supporting structure of a backrest two profile parts. This section is low in waste.
  • FIG. 1 a plan view of two extruded profiles with drawn cutting lines for cutting of profile parts in a second embodiment of the invention, which are assembled into a supporting structure of a backrest, - -
  • FIG. 4 shows a plan view of the supporting structure of a backrest, which is composed of profile parts cut out of the profiles according to FIG. 3
  • FIG. 5 shows a section A-A according to FIGS. 1 and 3
  • Fig. 6-11 a detail B of FIG. 5 in various embodiments and on enlarged scales
  • Fig. 12 is a plan view of the supporting structure of a backrest in a further embodiment.
  • each of the profiles 1, 2 consists of two hollow frame portions 3, which communicate with each other through a plate portion 4.
  • the cross section of the profiles 1, 2 is apparent from the illustration of FIG. 5.
  • the profiles 1, 2 differ in this embodiment, only in that the plate portion 4 of the profile 1 is wider than the plate portion 4 of the profile. 2
  • profile parts 5 are separated by cutting. These profile parts 5 are identical and have the shape of an isosceles triangle in plan view. Each profile part 5 is due to the cutting guide of a hollow frame portion 5.1 and a Piatte Hoch 5.2.
  • profile parts 6 are separated by cutting.
  • the profile parts 6 have in plan view, the shape of an isosceles triangle and each consist of a hollow frame area 6.1 and a plate area 6.2.
  • a difference between the profile parts 5 and 6 is that the base angle ⁇ of the profile parts 5 are greater than the base angle ß of the profile parts 6.
  • the profile parts 5 and 6 are mitred in such a way, - - that their base angles ⁇ and ß complement each other to 90 °.
  • the height h of the profile parts 5 is greater than the height h of the profile parts 6, since the plate portion 4 of the profile 1 is wider than the plate portion 4 of the profile 2.
  • Each profile part 10 in turn has a hollow frame portion 10.1 and a plate be rich 10.2. From the extruded profile 9 profile parts 11 are separated, which have the shape of a symmetrical trapezium in plan view.
  • the cutting guide for separating the profile parts 11 is shown in Fig. 3. The cutting guide is chosen so that waste is produced in as minimal a frame as possible.
  • Each of the profile parts 11 in turn has a Hohi- frame area 11.1 and a plate area 11.2. - -
  • each two profile parts 10 and 11 complement each other to a support structure 7 of a backrest, as shown in FIG. 4.
  • the joining of the profile parts 10 and 11 takes place here also by welding.
  • the hollow frame portions 5 of the extruded profiles 1, 2, 8 and 9 are identical and designed with the same wall thickness, as shown in Fig. 6.
  • the extrusion technology offers the possibility of easily adapting the profile parts 5, 6, 10 and 11 to the strength requirements in accordance with their installation situation in the finished backrest.
  • This can z. B. by increasing the wall thickness in certain areas, such. B. is shown in Fig. 7 on the basis of the inner web 12 of the hollow frame portion 5, done, or by Eckversteifept 13, as shown in Fig. 8.
  • the hollow frame regions 5 according to FIGS. 10 and 11 can be optimized for bending or torsion by providing corresponding transverse webs 14 and 15, respectively.
  • FIG. 9 differs from that of Figure 6 in that in addition a hook-shaped in cross-section channel 16 is provided, the z. B. can serve the hanging of reference parts.
  • FIG. 12 another embodiment of a supporting structure 7 of a backrest is shown. This corresponds to the supporting structure 7 of Fig. 4 with the difference that the plate portions 10.2 and 11.2 of the profile parts 10 and 11 are not designed as wide as in the embodiment of FIGS. 3 and 4. This remains in assembled profile parts 10 and 11 in the central region of the supporting structure 7 a rectangular hole which is closed by welding a sheet metal part 17. - -
  • Attachments, locking devices, etc. are then welded or otherwise fastened to the supporting structures 7 produced in this way.

Abstract

La présente invention concerne un dossier rabattable pour un siège arrière d'un véhicule automobile, dont la structure porteuse se compose d'une plaque de base ayant un cadre périphérique creux. Un tel dossier doit être facile à construire, être facile à monter, entraîner des frais d'outillage relativement faibles et autoriser une construction souple. Afin d'atteindre ces objectifs, la structure porteuse (7) se compose de quatre pièces profilées (5, 6 ; 10, 11) faites dans un métal léger, en particulier un alliage d'aluminium. Les pièces profilées (5, 6 ; 10, 11) comportent chacune une partie de cadre creux (5.1, 6.1 ; 10.1, 11.1) et une partie plane (5.2, 6.2 ; 10.2, 11.2) et sont découpées avec onglets à partir de profils extrudés (1, 2 ; 8, 9) de manière à former dans leur état soudé la plaque de base ayant le cadre périphérique creux.
