Abstract

A vehicle, especially a minivan, having at least one rear seat located behind the front seat as viewed in the direction of travel. The seat has a seat back that can be pivoted onto a seat part. A floor pan is located in front of the rear seat in the vehicle floor for accommodating lowering of the rear seat. A folding mechanism pivots the rear seat, folded together by folding the seat back onto the seat part, into the floor pan. To achieve a limited floor pan thickness while retaining a seat height of the seat part of the rear seat that is determined by seating comfort, the folding mechanism has two front and two rear supports, each of the supports being pivotable around a pivot axis aligned transversely to the lengthwise direction of the vehicle and secured to the seat part. The supports hold the rear seat in its operating position at a predetermined seat height above the vehicle floor. The two front supports are mounted so that their ends remote from the seat part can pivot around a pivot axis that is aligned transversely to the lengthwise direction of the vehicle and is defined below the vehicle floor, while the two rear seats are each mounted releasably in a supporting bearing accommodated in the vehicle floor.

7. Vehicle according to one of claim 1, wherein the floor pan is extended up to a point below the at least one front seat and additionally receives a spare wheel.

8. Vehicle according to claim 2, wherein the floor pan is extended up to a point below the at least one front seat and additionally receives a spare wheel.

9. Vehicle according to claim 4, wherein the floor pan is extended up to a point below the at least one front seat and additionally receives a spare wheel.

10. Vehicle according to claim 5, wherein the floor pan is extended up to a point below the at least one front seat and additionally receives a spare wheel.

11. Vehicle according to claim 6, wherein the floor pan is extended up to a point below the at least one front seat and additionally receives a spare wheel.

12. Vehicle according to claim 3, wherein said at least one front seat comprises a device for at least one of displacing said at least one front seat lengthwise by at least one motor and adjusting a pitch of a seat back of said at least one front seat by at least one motor;

and

a control device provided for controlling, said at least one motor, wherein a control function is integrated into the control device, said function causing a displacement movement of the front seat in a way that one of increases the distance from the rear seat and causes an erecting movement of a seat back of the front seat into a specified position when the floor pan opening is exposed by removing the floor panel, allowing the rear seat to pivot into the floor pan, unimpeded by the seat back of the front seat.

13. Vehicle according to claim 5, wherein said at least one front seat comprises a device for at least one of displacing said at least one front seat lengthwise by at least one motor and adjusting a pitch of a seat back of said at least one front seat by at least one motor;

and

a control device provided for controlling said at least one motor, wherein a control function is integrated into the control device, said function causing a displacement movement of the front seat in a way that one of increases the distance from the rear seat and causes an erecting movement of a seat back of the front seat into a specified position when the floor pan opening is exposed by removing the floor panel, allowing the rear seat to pivot into the floor pan, unimpeded by the seat back of the front seat.

14. Vehicle according to claim 6, wherein said at least one front seat comprises a device for at least one of displacing said at least one front seat lengthwise by at least one motor and adjusting a pitch of a seat back of said at least one front seat by at least one motor;

and

a control device provided for controlling said at least one motor, wherein a control function is integrated into the control device, said function causing a displacement movement of the front seat in a way that one of increases the distance from the rear seat and causes an erecting movement of a seat back of the front seat into a specified position when the floor pan opening is exposed by removing the floor panel, allowing the rear seat to pivot into the floor pan, unimpeded by the seat back of the front seat.

15. Vehicle according to claim 7, wherein said at least one front seat comprises a device for at least one of displacing said at least one front seat lengthwise by at least one motor and adjusting a pitch of a seat back of said at least one front seat by at least one motor;

and

a control device provided for controlling said at least one motor, wherein a control function is integrated into the control device, said function causing a displacement movement of the front seat in a way that one of increases the distance from the rear seat and causes an erecting movement of a seat back of the front seat into a specified position when the floor pan opening is exposed by removing the floor panel, allowing the rear seat to pivot into the floor pan, unimpeded by the seat back of the front seat.

16. Vehicle according to claim 1, wherein the vehicle is a minivan.

17. A seating arrangement for a vehicle comprising:

a vehicle floor,

a front seat,

a rear seat disposed behind the front seat and having a seat part mounted on the vehicle floor and a seat back pivotally connected to the seat part,
