  • the carrier 41 are additionally connected via angle 60 with the hollow profile carrier 47. Between the support members 41 45 longitudinally extending carrier 43 are attached. Between the longitudinally extending supports 43, in turn, vertically extending supports 44 are mounted. In addition, they serve in this particular embodiment also for the attachment of comfort devices, such as magazine holders, storage compartments, cabinets, operating devices o. ⁇ .
  • On the lower plate 51 is a base 70th mounted for a magazine rack.
  • the air channel elements 42 having a tubular cavity have a high rigidity and a relatively high mass, which contributes to the reduction of the natural frequency of the bottom pan.
  • Towards the cabin cover plates 55 are attached to the supports 41 and 46 (s. Fig. 6c ).
  • FIG. 6a and 6b As in Fig. 6a and 6b is shown, at the top of the side part 11 on the air channel elements 42 and the support 41 and 46, an upper plate 52 is placed, which where the air duct elements 42 are attached, has openings which are congruent with the openings 50 of the air duct elements 42. An These openings close up further air channel elements 56 in the region of the cabin side wall 8a, as in the Fig. 6c shown.
  • Fig. 6c shows the view interconnected cabin side walls 8a and 8c from the outside, ie by the (not shown) car body side wall 4a toward the cabin interior. Visible are the sides of the cabin side walls 8a and 8c, which are opposite the car body side wall 4a.
  • the plate 52 forms the upper end of the side part 11 of the floor pan.
  • the side part 11 of the bottom pan has a greater thickness, ie a greater extent transverse to the vehicle longitudinal direction, as the adjoining side wall 8 a, as in the Fig.1 . 2 and 6c is recognizable.
  • the side part 11 together with the plate 52 protrudes into the interior of the cabin, as in Fig. 1 and 6c
  • the panels 52 form a shelf or sill for the window 13a provided above in the cabin side wall 8a.
  • the side member 11 has, in addition to the upper plate 52 and a lower plate 51, which is arranged at the lower end of the side part and as the upper plate extends in the vehicle longitudinal direction. Due to their rigidity, the upper plate 52 and the lower plate 51 also assume a supporting function for the side part 11 of the floor pan. Corresponding as stated above applies to the side part 11 mirror-symmetrical side part 12th
  • the Fig. 7a and 7b show an elastic connection between a cabin side wall and a side part of the floor pan in the region of the transition between two side wall elements 8a and 8c.
  • the Fig. 7a shows a part of the Fig. 6c in the region between the windows 13a and 13c, where two side wall elements 8a and 8c are interconnected.
  • Fig. 7a shows how Fig. 6c shows the view of cabin side walls 8a and 8c from the outside, ie by the (not shown) car body side wall 4a toward the cabin interior.
  • In the lower part of the Fig. 7a is a section of the side part 11 of the floor pan with the air duct / support members 42 and the upper plate 52 shown.
  • Fig. 7b shows the structure in section transverse to the longitudinal axis of the vehicle, wherein the cabin space 1 is arranged on the left side.
  • the profile 105 opens on the left side of the cabin interior 1 in a hollow profile part, which is approximately quarter-circle in cross section.
  • This hollow profile part forms the transition between the upper plate 52 and the side walls 8a, 8c and conceals the gap between the plate 52 and the side walls as a diaphragm.
  • Air duct elements 56 are shown in the region of the cabin side walls 8a and 8c, which continue the air duct of the carrier / air duct elements 42 upwards and laterally, below the windows 13a, 13c.
  • the air channel elements 56 sit with a flange or a projection 111 on the profile part 105. Between the projection 111 and the profile part 105, an elastic sealing layer is arranged, which is not shown in this figure.
  • This elastic sealing layer for example an elastic sealing foam, is an elastic connection between a cabin side wall and a side part of the floor pan, which allows the side part of the floor pan relative to the wall parts which are fixed in the region of the windows relative to the surrounding car body, and relative to the air channel elements 56, which are fixed to the wall parts, can move, for example, during a movement of the trough in the Z direction downwards.
  • FIG. 7b The connection between the side walls 8a and 8c is based on FIG. 7b explained.
  • a here in cross-section hat-shaped profile 101 covers as cover the slot between two side wall portions 8a and 8c. It may for example be attached to the side wall parts with an adhesive connection or Velcro connection.
  • a section through the center of the profile 101 is shown, approximately at the level of the connecting line of the walls 8a and 8c, where the profile is spaced from the walls 8a and 8c.
  • an angle 100 is set, which is fastened with its horizontal leg 112 to a pin 104.
  • the bolt 104 is part of the profile 105.
  • the vertical leg 110 of the angle 100 bears against the profile 101.
  • a protruding from the profile 101 and the profile carrier parallel leg 106 has a vertical slot.
  • This slot is a horizontally projecting from the vertical leg 110 of the angle 100 pin 107 with an inserted thereon elastic ring 102 introduced.
  • the bearing of the pin 107 with the elastic ring in the vertical slot allows a resilient relative movement of the bottom pan and the upper board 52 against the cabin side walls 8a and 8c in the z direction in the region of the transition between the side walls.
