It is an object of the invention to provide a motor vehicle in which, in each case, three or more child seats can be arranged adjacent to one another on a second seat row and/or further rear seat row.

This and other objects are achieved by a motor vehicle according to the invention having a body which has a passenger cell with a vehicle interior. On a floor of the vehicle interior, there are provided at least one front seat and at least one rear seat row. The rear seat row has at least two seating positions. The seating positions provided on the rear seat row are composed in each case of a seat base part with seat base surfaces and of a backrest with backrest surfaces. In each case one lateral support is formed on lateral ends of the rear seat row, wherein in each case one middle seat base surface section is formed between the two seat base surfaces.

The two seat base surfaces can advantageously be displaced from a lowered position into a raised position and vice versa, wherein the two optionally provided lateral supports can be moved from a raised position into a lowered position and the middle seat base surface section can be moved from a raised position into a lowered position, such that the upwardly directed outer surfaces of the lateral supports, the upwardly directed outer surfaces of the seat base surfaces and the upwardly directed outer surface of the middle seat base surface section form a flat seat base surface of the seat bench.

In an advantageous embodiment, the seatbelt fasteners, the seat belts, the seatbelt retractors and the fastening devices for the child seats can be displaced from a respective position for a non-flat seat base surface into corresponding positions for a flat seat base surface of the seat bench, and vice versa.

In an advantageous embodiment, in each case at least one airbag is arranged in the optionally provided lateral supports.

Other objects, advantages and novel features of the present invention will become apparent from the following detailed description of one or more preferred embodiments when considered in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE DRAWINGS

FIG. 1 is a schematic illustration of a rear seat row 2 of a motor vehicle 1 (not illustrated in any more detail). In the embodiment shown, the rear seat row 2 is composed of a seat bench 3 with two sunken seat base surfaces 4 and 5. The two seat base surfaces 4 and 5 are spaced apart from one another by a middle seat base surface section 6. The middle seat base surface section 6 is generally narrower than the two seat base surfaces 4 and 5.

On the two lateral ends 7, 8 of the seat bench 3 there is formed a respective height-adjustable lateral support 9, 10. The seat bench 3 is adjoined by a backrest 13. The backrest 13 may be of dividable or non-dividable form.

In the embodiment shown, the respective seat base surface 4 and 5 of the seat bench 3 is assigned a respective backrest surface 14, 15 of the backrest 13. The middle seat base surface section 6 is assigned a backrest surface 16. This yields two outer, lateral seats 17 and 18 and a middle seat 19. Arrangement of child seats is possible only on the two sunken seat base surfaces 4 and 5.

In FIG. 1, the two lateral supports 9, 10 are, in each case, situated in a maximally raised or upwardly adjustable position 11, 12, and the middle, height-adjustable seat base surface section 6 has also been adjusted into a maximally raised position 20. In FIG. 1, the two seat base surfaces 4 and 5 are, in each case, situated in a maximally lowered position 21 and 22. The seat bench 3 thus has a non-flat seat base surface 3a.

In FIG. 2, the seat base surfaces 4 and 5 that are shown have been displaced upward by a height z_4,max, z_5,max by way of a raise/lower device (not illustrated), whereas the two lateral supports 9 and 10 and the middle seat base surface section 6 have been lowered by a height z_6,min, z_9,min, z_10,min into a minimal position.

In FIG. 2, the two lateral supports 9 and 10 and the middle seat base surface section 6 are situated in a maximally lowered position 23, 24 and 25. The two seat base surfaces 4 and 5 have been displaced upward into a maximally raised position 26, 27.

The lowering of the two lateral supports 9, 10 and of the middle seat base surface section 6 and the raising of the two seat base surfaces 4 and 5 is performed so as to give rise to a flat seat base surface 28 of the seat bench 3, as shown in FIG. 2. On the flat seat base surface 28 of the seat bench 3, it is thus possible for three child seats 29, 30, 31 to be arranged adjacent to one another, as shown by dashed lines in FIG. 2.

FIGS. 3 to 5 show the arrangement and displaceability of the three provided seatbelt fasteners 32, 33, 34 for the three seatbelts 35, 36, 37 and the three seatbelt retractors 38, 39, 40 for the three seatbelts 35, 36, 37. Furthermore, FIGS. 3 to 5 show a displaceability of, in each case, two (ISOFIX) fastening points 41, 42 and also 43 and 44.

FIG. 3 shows a state in which the two seat base surfaces 4 and 5 are situated in the lowered position 21, 22 corresponding to FIG. 1. When the seat base surfaces 4 and 5 are raised into the respective maximally raised position 26, 27 shown in FIG. 2, with the lateral supports 9, 10 simultaneously being lowered into the lowermost position 23, 24, the seatbelt fasteners 32, 33, 34 are displaced in terms of position, the seatbelts 35, 36, 37 are displaced in terms of position, the seatbelt retractors 38, 39, 40 are displaced in terms of position, and the ISOFIX fastening devices 41, 42 and 43, 44 are displaced in terms of position from the respective positions 45, 46, 47 shown in FIG. 3 for the seatbelt fasteners 32, 33, 34, from the respective positions 48, 49, 50 shown in FIG. 3 for the seatbelts 35, 36, 37, from the respective positions 51, 52, 53 shown in FIG. 3 for the seatbelt retractors 38, 39, 40, and from the respective positions 54, 55 and 56, 57 shown in FIG. 3 for the ISOFIX fastening devices 43, 44 into the positions 58, 59, 60 shown in FIG. 4 for the seatbelt fasteners 32, 33, 34, into the respective positions 61, 62, 63 shown in FIG. 4 for the seat belts 35, 36, 37, into the respective positions 64, 65, 66 shown in FIG. 4 for the seatbelt retractors 38, 39, 40, and into the respective positions 67, 68 and also 69 and 70 shown in FIG. 4 for the respective (ISOFIX) fastening devices 41, 42 and also 43 and 44.

The upwardly directed outer surfaces 71, 72 of the lateral supports 9, 10, the upwardly directed outer surfaces 73, 74 of the seat base surfaces 4, 5 and the upwardly directed outer surface 75 of the middle seat base surface section 6 thus form a flat seat base surface 28 of the seat bench 3.

As is evident from a comparison of FIGS. 3 and 4, the seatbelt 35 is displaced to the left in the direction of the outer lateral end 7 of the seat bench 3. Correspondingly, the seatbelt fastener 32 moves to the left and upward by a predefined distance. The seatbelt retractor 38 likewise moves to the left.

The seatbelt 36 for the middle seat 19 moves to the right together with the seatbelt retractor 39. Correspondingly, the seatbelt fastener 33 is displaced to the left. The seatbelt 37 moves together with the seatbelt retractor 40 to the right. Correspondingly, the seatbelt fastener 34 moves upward. The fastening devices 41, 42 move to the left into a higher position.

The (ISOFIX) fastening devices 43, 44 move from the sunken positions 41, 42 and 43, 44 into the higher positions 67, 68 and 69, 70 and to the right, in the direction of the lateral end 8 of the seat bench 3, by a predefined distance.

FIG. 5 shows a state in which, by contrast to the state shown in FIG. 4, the left-hand lateral support 9 has, for example owing to a side-on impact, been activated and inflated or moved, and is thus situated in the raised position 11.

The foregoing disclosure has been set forth merely to illustrate the invention and is not intended to be limiting. Since modifications of the disclosed embodiments incorporating the spirit and substance of the invention may occur to persons skilled in the art, the invention should be construed to include everything within the scope of the appended claims and equivalents thereof.
