Referring to FIGS. 3 and 4, there are provided perspective views showing lateral slide rails 29 for the center row seats 12, 113. The slide rails 29 are buried in the floor parallel with each other to extend in the lateral direction. The slide rails 29 are provided with strikers 30 and lock and lever mount 31 for mounting the center row seats at a desired position. Each of the seats is formed with a book 33 for engaging the striker 30 and a lock and lever structure for engaging the lock and lever mount 31.

In FIG. 5, there is generally shown a relationship between the lateral slide rails 29 and longitudinal slide rails 32. As shown in FIG. 5, the longitudinal rails 32 are fixed to the center row seat 12, 13. To a lower side of each of the slide rails 32 is fixed a hook 33 which is brought into engagement with the rail 29. As shown in FIG. 6, the slide rail 29 is slidably provided with a slide guide 34 for supporting the striker 30 which is brought into engagement with the hook 33 so that the right and left center row seats 12 and 13 are movable in the lateral direction along the lateral slide rails 29.

The lateral slide rails 29 are buried so as to be installed within a pair of recesses 8a, 8a formed on the floor panel 8. Referring further to FIG. 7, the slide rails 29 are constituted by a pair of long panel members of substantially S like configuration in section. The panel members are supported by the brackets 39 which are fixed to the floor panel by means of bolts. The brackets 39 are disposed at a predetermined interval in the lateral direction, fixed to a horizontal flange portion of the panel member forming the slide rail 29 at one end for supporting the panel member and fixed to the floor panel 8 through bolts 40.

As shown in FIG. 6, beneath the recess of the floor panel is positioned a cross member 41 of a channel configuration which is fixed to the slide rails 29 at opposite ends so that a cross sectioned panel structure extending in the lateral directions is formed by the cross member 41 and a lower surface of the floor panel 8.

An upper surface of the slide rail 29 is substantially aligned with the upper surface of the floor panel 8. As a result, when the center low seats 12 and 13 are removed, a substantially flat floor surface is formed although the strikers 30 and the mounts 31 are slightly projected upwardly.

When the seats 12, 13 are slid with guides 35 which engage the longitudinal slide rails 32, the seats 12 and 13 can be moved in the longitudinal direction of the vehicle along the longitudinal rails 32. On top of that, the center row seats 12, 13 can be removed by disengaging the hook 33 form the strikers 30.

Further, in the illustrated embodiment, the front row seats 9 and 10 are also removable. These seats can be mounted oppositely longitudinally.

Hereinafter, with the vehicle structure having the above seat device, how to utilize the cabin space is to be explained.

A basic seat arrangement of the illustrated vehicle is, as shown in FIG. 1, of a captain mode in which the front row seats 9, and 10, the center row seats 12 and 13, and the rear row seat 14 are all arranged for a forward looking attitude. In this case, the center row seats 12 and 13 are fixed to produce a distance in between.

As shown in FIG. 8, it is possible to provide so called a bench mode in which one of the seats 12 and 13 is slid in the lateral direction to either one side so that two seats 12 and 13 are positioned at one side in contact with each other with regard to the lateral direction of the vehicle 1.

As shown in FIG. 9, with the bench mode, the seats 12, 13 and 14 are all entirely folded to establish a two seating vehicle condition. With this condition, the cabin space rearward of the front row seats 9 and 10 can be widely opened so that a big amount of luggage can be loaded.

In addition, as shown in FIG. 10, the assistant's seat can be entirely folded to obtain a further open space in the cabin. As shown in FIG. 11, the center row seats 12 and 13 are moved laterally toward either one side of the cabin so as to be brought into contact with each other and entirely folded. With this arrangement, flat back surfaces of the seat backs 16b of the seats 12 and 13 can be utilized like a table. In this case, if the center row seats 12 and 13 are constituted in a manner that the seat backs 16 are formed with hard and horizontal flat surfaces in the back sides when entirely folded, the back sides of the seat backs of the center row seats 12 and 13 can be effectively used like a table.

Further, as shown in FIG. 12, when the front row seats 9 and 10 are arranged oppositely in the longitudinal direction of the vehicle and the center row seats 12 and 13 are entirely folded, a face to face mode can be established in which the persons seated in the front row seats 9 and 10 face the persons seated in the rear row seat 14 over the center row seats 12 and 13. In FIG. 13, a condition is shown that the center row seats 12 and 13 are removed. With this arrangement, a widely open space can be obtained forward of the rear row seat 14. The removed center row seats 12 and 13 can be stored in the storage pan 20. Alternatively, they can be arranged rearward of the front row seats 9 and 10 with the entirely folded condition as shown in FIG. 14.

Further, as shown in FIG. 15, when the center row seats 12 and 13 and the rear row seat 14 take full flat conditions, it is possible to establish a bed like condition by means of the seats. In this case, if the head rests 17 are able to be removed and mounted laterally thereto, a wider flat bed like condition can be established with this arrangement.

Further, as shown in FIG. 16, when the rear row seat 14 is retracted into the storage pan 20, it is possible to obtain a widely open space rearward of the center row seats 12 and 13 in the cabin. With this arrangement, a widely open space of a flat surface in line with the floor surface can be formed at a side of the side door extending from the rearward of the assistant's seat to the rear end of the cabin space. As a result, a long and wide luggage such as ski, table, mattress can be loaded along a longitudinal and vertical side of the vehicle as shown in FIG. 16. This is because a full space from the floor surface to a ceiling of the cabin can be obtained with no obstacle.

Further, the center row seats 12 and 13 can be removed with the rear seat 14 being retracted in the storage pan 20 as shown in FIG. 17. As a result, a flat and widely open space in line with a floor level can be established rearward the front row seats with a full width to the rear end of the cabin. Such wide and open space of the cabin cannot be established in any conventional passenger vehicle. Thus, the vehicle according to the present invention can be used like a truck. In this case, the center row seats 12 and 13 can be stored rearward of the front row seats 9 and 10 with an entire folded condition (FIG. 18). In addition, when the front row seats 9 and 10 and the center row seats 12 and 13 are fully reclined to establish substantially full flat condition with the rear row seat 14 being arranged for a normal seating condition, it is possible to obtain a broad and open bed like condition forward the rear row seat 14. In this case, if the head rest 17 is removed and arranged between the seats, it is possible to form a wide and flat surface substantially completely covered by the seats and head rests.

As shown in FIG. 20, when the rear row seat 14 is rolled back with keeping the normal seating attitude around a hinge 37 which is disposed at a rear side of the seat so as to be seated on the seat back 16 in lieu of the seat cushion 15 with an inverted condition.

In this case, the seat back 16 takes a horizontal state. The storage pan 20 positioned under beneath the seat back 16 so that a person can sit on the seat back 16 with a rear door 40 open. Further, as shown in FIG. 21, one of the center row seats 12 and 13 can be removed to leave only one.

Referring to FIG. 22, there is shown another embodiment in accordance with the present invention. In this embodiment, the center row seats are constituted by three seats in which a middle seat 36 is not mounted on the rails 29 and removably mounted. Therefore, when the middle seat 36 is removed, it is possible to utilize the cabin space with broad variations as mentioned in connection with the former embodiment. When the middle seat 36 is attached, a wider bench mode can be established with the center row seats 12, 13 and 36.

As mentioned above, according to the present invention, the cabin space can be utilized with many variations as a whole so as to improve the operability of the cabin space drastically. Thus, the utility of the vehicle can be greatly expanded.

Although the present invention has been explained with reference to a specific, preferred embodiment, one of ordinary skill in the art will recognize that modifications and improvements can be made while remaining within the scope and spirit of the present invention. The scope of the present invention is determined solely by the appended claims.
