Movement adjustment system

Abstract

In order to suppress a claustrophobic feeling that a person sitting on a rear seat receives due to a front seat, and to make the front seat easy to use as an ottoman by the person, a movement adjustment system is used for a passenger seat and a rear seat, and includes a slide rail for moving the rear seat in the front to back direction, and a control part for changing the movement region of the rear seat by the slide rail. The passenger seat has a seat cushion, and a seat back mounted to be changeable between an upright state and a lowered state with respect to the seat cushion. The control part changes the movement region so that the passenger seat and the rear seat can come closer when the seat back of the passenger seat is in the lowered state than in the upright state.

What is claimed is: 
     
         1 . A movement adjustment system used for conveyance seats including a front seat and a rear seat, the movement adjustment system comprising:
 a moving mechanism configured to move at least one of the front seat and the rear seat in a front to back direction; and   a movement region change part configured to change a movement region of the at least one of the front seat and the rear seat moved by the moving mechanism, wherein   the front seat has a seat cushion, and a seat back mounted to be changeable between an upright state and a lowered state with respect to the seat cushion, and   the movement region change part is configured to change the movement region so that the front seat and the rear seat can come closer when the seat back of the front seat is in the lowered state than when the seat back of the front seat is in the upright state.   
     
     
         2 . The movement adjustment system according to  claim 1 , wherein
 the clearance between the front seat and the rear seat includes a first clearance in which an occupant of the rear seat can put his feet through between the front seat and the rear seat, and a second clearance in which the occupant cannot put his feet through between the front seat and the rear seat, and   only when the seat back of the front seat is in the lowered state, the movement region change part sets the movement region to a range in which the clearance between the front seat and the rear seat is the first clearance and a range in which the clearance between the front seat and the rear seat is the second clearance.   
     
     
         3 . The movement adjustment system according to  claim 1 , wherein when the front seat and the rear seat are in the positions close to each other, the moving mechanism moves the front seat or the rear seat so that the relative position of the rear seat to the front seat is higher than when the front seat and the rear seat are in the positions separated from one another. 
     
     
         4 . The movement adjustment system according to  claim 1 , comprising a detection part for detecting the lowered state and the upright state of the seat back of the front seat, wherein
 the movement region change part:   determines the lowered state and the upright state of the seat back based on the signal obtained from the detection part, and   when the seat back is in the lowered state, changes the movement region so that the front seat and the rear seat can be moved to the positions close to each other than when it is in the upright state.   
     
     
         5 . The movement adjustment system according to  claim 1 , comprising another detection part for detecting the existence of a sitting person on the front seat, wherein
 the movement region change part:   determines the presence and the absence of the sitting person on the front seat based on the signal obtained from the another detection part, and   when the sitting person is absent, changes the movement region so that the front seat and the rear seat can be moved to the positions close to each other than when the sitting person exists.   
     
     
         6 . The movement adjustment system according to  claim 1 , wherein
 the front seat and the rear seat are composed of a plurality of rows, and   of the front seat or the rear seat in one row, to one whose movement region is changed by the movement region change part, a table projecting in front of the rear seat in another row adjacent to the one row is mounted.   
     
     
         7 . The movement adjustment system according to  claim 1 , wherein
 the front seat and the rear seat are composed of a plurality of rows,   of the front seat or the rear seat in one row, one whose movement region is changed by the movement region change part has another seat cushion, and another seat back mounted to the other seat cushion, and   the another seat back is mounted to the another seat cushion to be rotatable to the other row side.   
     
     
         8 . The movement adjustment system according to  claim 1 , wherein
 the front seat and the rear seat are composed of a plurality of rows,   of the front seat or the rear seat in one row, one whose movement region is changed by the movement region change part has another seat cushion, and another seat back mounted to the other seat cushion,   the other seat back has edge portions that bulge forward on both sides of a seat width direction, and   the other row side in the edge portion is formed to be more compressively deformable than the counter side of the other row side.   
     
     
         9 . The movement adjustment system according to  claim 1 , wherein
 the front seat and the rear seat are composed of a plurality of rows,   the movement region change part changes the movement region of at least one of the front seat and the rear seat in one row so that the front seat and the rear seat can come closer when the seat back of the front seat is in the lowered state than in the upright state,   a supply opening of an air-conditioner is arranged on the other row side of at least one of the front seat and the rear seat in the one row, and   air flow is provided obliquely backward from the supply opening toward the rear seat in the other row.   
     
     
         10 . The movement adjustment system according to  claim 1 , wherein
 the front seat and the rear seat are composed of a plurality of rows,   the movement region change part changes the movement region of the rear seat in one row so that the front seat and the rear seat can come closer when the seat back of the front seat is in the lowered state than in the upright state,   the rear seat in the other row adjacent to the one row includes a belt buckle into which a tongue of a seat belt is inserted, and   the rear seat in the one row is changed in the movement region by the movement region change part to be movable to the front side in the front to back direction than the belt buckle of the rear seat in the other row when the seat back of the front seat is in the lowered state.
