The invention is based on a seat part 12 the rear seat row of the motor vehicle described. The seat part 12 is arranged independently of the illustrated backrest part movable. The function of the seat part 12 Can also be on a rear seat, which consists of several seat parts 12 exists, be transferred. In this case, the seat is the seat part 12 dar. The 1A is the 1B associated, in a single representation provided with the same reference numerals components, in particular the seat part 12 , represents. The seat part 12 has a seat top side 14 and a seat bottom 16 on. The seat part 12 is made of a seat upholstery 18 and a seat base 20 educated. Side of the seat part 12 there is a groove-like backdrop 22 , preferably on both sides of the seat part 12 is arranged, but can also be arranged only on one side. The scenery 22 indicates a first stop 24 and a second stop 26 on. In the in the 1A and 1B shown use position for receiving an occupant is the backdrop 22 arranged substantially horizontally. Below the seat part 12 is in the range of a body 30 a recording room 28 arranged. At the front edge of the recording room 28 that has a recess in the bodywork 30 represents is near the front edge of the seat part 12 a swivel arm 32 body shop arranged. The swivel arm 32 is rotatably formed on a first horizontal pivot axis A. As the 1A and 1B show, the swivel arm engages 32 in the use position of the seat part 12 in the groove-like scenery 22 and is how 1B enlarged, in this position between the first stop 24 and the second stop 26 arranged to form a second horizontal pivot axis B.

The 2A to 5B show a pivoting movement of the seat part 12 from the use position to a first non-use position P ₁ in a sequence-like representation. The 2A . 3A . 4A . 5A show essentially the positioning of the seat part 12 within the motor vehicle interior, wherein the 2 B . 3B . 4B . 5B Sequentially in a detailed manner, the pivoting movement about the first and second pivot axis A, B and the arrangement of the pivot arm 32 in the scenery 22 between the first stop 24 and the second stop 26 demonstrate.

For the sake of simplicity, the pivoting movement of the seat part will be described briefly below 12 based on 2 B . 3B . 4B . 5B described. The 2A . 3A . 4A . 5A show the same process in the overall context in the vehicle interior.

First, how 2 B shows, the swivel arm 32 from the central position between the first stop 24 and the second stop 26 to the second stop 26 shifted. By pivoting the seat part 12 around the first pivot axis A according to 3B hangs the seat part 12 according to 3B and 4B upon transfer from the substantially horizontal use position into the substantially vertical first non-use position P ₁ according to FIG 5B in the second stop 26 in its highest position on the swivel arm 32 , 5B shows the first non-use position P ₁ , the - as out 5A is apparent - now the recording room 28 in the body 30 releases. In this first non-use position P ₁ can now load in an advantageous manner 34 , which is not shown in the figures, in the receiving space 28 be spent.

The swing-and-tilt movement of the seat part 12 is in accordance with the 1 to 5 either by means of a lock or the like of the swivel arm 32 generated or is limited by the fact that the seat part 12 with its leading edge the bottom of the body 30 reached.

The 6A . 7A . 8A . 9A . 10A again show the position of the seat part in the side view 12 within the motor vehicle interior during the pivoting movement from the first non-use position P ₁ in a second non-use position _P2. The 6B . 7B . 8B . 9B . 10B again show in individual representations, the pivoting movement of the seat part 12 with the same reference numerals, on the basis of which the further description is made.

As 6B shows, becomes the seat part 12 from the position of 5B First raised slightly, leaving the seat part 12 facing end of the swing arm 32 now at the first stop 24 the scenery 22 attacks. By this substantially vertically upwardly displaced movement of the seat part 12 can the seat part 12 now by simultaneously pivoting about the first or second pivot axis A, B via the individual positions shown in sequence 7B . 8B . 9B . 10B be turned. 10A . 10B Finally, represent the second non-use position P ₂ in its final position. It will be seen that the seat top side 14 namely, the seat cushion 18 , now on the previous seat underside 16 according to 1A is arranged. The scenery is like in 1A and 1B again arranged substantially horizontally.

11A and 11B show the already described pivoting operation of the seat part as part of a rear seat 12 from the use position of the motor vehicle seat 10 in a perspective view. 11B shows the perspective view during the pivoting movement of the seat part 12 , In this further possible embodiment variant, the swivel arm 32 essentially centrally above the receiving space 28 at the body 30 (not shown in detail) arranged. The 11A (Starting position) and in particular the 11B (Swivel position analogous to the first non-use position P ₁ ) shows only the other basic arrangement of the swivel arm 32 this embodiment. To achieve the same functionality as in the 1A to 10B is described, the pivot arm moves 32 also about the first and second horizontal pivot axis A and B and is also analogous to the 1A to 10B in a backdrop, not shown 22 movably arranged, so that at substantially central arrangement of the pivot arm 32 the same functions are possible with the same described features. In contrast to the previous figures, however, in this embodiment, only smaller items - load 34 - in the recording room 28 be brought, since the central arrangement on the pivot axis A of the seat part in the substantially vertical position the receiving space 28 not completely releases, as it is approximately in the 7A is shown.

From the perspective 12A and 12B goes according to the one shown in the side view 10A . 10B and also the 11A . 11B a further variant essential to the invention, namely, that the seat part underside 16 closure elements 36 which, in the turned position of the seat part 12 are accessible. The closure elements 36 close the seat part body 20 such that only an opening of the closure elements 36 according to 12B the interior of the seat part body 20 releases. This thereby released depression in the seat part body 20 can in an advantageous way, like 12B indicates, to be used, cargo 34 on the seat part 12 to spend non-slip. This inventive concept therefore has the seat part 12 in the second non-use position to a different use or another function regardless of the normal suitability for receiving occupants in the use position. The advantage is in particular that the seat part 12 Depending on the position, you can take on or facilitate another function. The well-known use position serves to accommodate the occupant. The first non-use position P ₁ is used for the shipment of cargo 34 in the recording room 28 and for extended through-loading, inasmuch as the backrest part offers such a possibility. The second non-use position P _2, in turn, can for non-slip deposition of objects in the recess of the seat part body 20 be used.
