The back 32 is superposed, and the sub seat back 32 is configured to be usable as an armrest.

  According to this configuration, when the sub seat back 32 and the sub seat cushion 31 are interlocked by the sub seat interlocking mechanism 50 and moved to the arrange position, the sub seat cushion 31 is superposed below the sub seat back 32. Since the sub-seat back 32 in the arrangement position can be used as an armrest, the comfort of the passenger can be improved.

  In addition, when the sub seat back 32 and the sub seat cushion 31 are moved to the arrange position, the pair of main seat backs 20 and 20 and the pair of main seat cushions 19 and 19 come close to each other in the vehicle width direction. It is configured to be movable toward the direction.

  According to this configuration, when the sub seat S moves to the arrangement position, the pair of main seat backs 20 and 20 and the pair of main seat cushions 19 and 19 can be variably adjusted in the vehicle width direction.

  The pair of main sheets M1 and M2 are provided so as to be movable obliquely rearward so that the main sheets M1 and M2 approach each other.

According to this configuration, the slide rails extending in the lateral direction and the front-rear direction are not required, so that the main seats M1, M2 can be moved rearward with a simple structure.
Further, a pair of left and right wheel houses 22 and 22 projecting inward in the vehicle width direction toward the vehicle interior 2 are provided behind the main seats M1 and M2, and the main seats M1 and M2 are provided with a pair of left and right wheel houses 22. , 22 is configured to be movable.

According to this configuration, since the pair of main seats M1, M2 moves between the pair of left and right wheel houses 22, 22 protruding toward the passenger compartment 2, the comfort of the rear seat passenger sitting on the main seats M1, M2 is improved. Can be achieved.
In the above embodiment, the vehicle seat device is applied to the second row of the front seats 14 and the rear seats 18 arranged in a plurality of rows (two rows) in the longitudinal direction of the vehicle. Of course, in the seat structure in which a total of three rows or a total of four rows are arranged in the front-rear direction, the vehicle seat device described above may be applied to the rear row seats close to the wheel house.
