Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicular seat apparatus that can be reclined by, for example, dividing a seat back of a rear seat.

[0002]

2. Description of the Related Art Japanese Patent Laying-Open No. 9-86241 discloses a structure in which a seat back of a rear seat is divided into two parts so that each seat back can be reclined.

[0003]

The conventional rear seat is
The seat back is divided into two parts at a ratio of 5: 5 or 6: 4 in the width direction of the vehicle, so that each seat back can be reclined one step forward (in a state of being fallen on the seat cushion) and several steps backward. It is possible to access the rear trunk room by tilting one seat back horizontally into the seat cushion, and it is possible to load long luggage such as skis and surfboards,
The other seat back secures a space for adults to sit on.

However, in the above-mentioned conventional seat back, for example, when a wide seat back is tilted down and an adult sits on the narrow seat back side, the seating space is narrow, and the seat back side is narrow. When the user sits down and reclines the seat back rearward, a step is generated between the two seat backs, so that the back holding ability and the riding comfort due to the seat back deteriorate.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has as its object to provide a vehicle seat device capable of securing a large area of a seat back even when reclining, improving a holdability of a back and improving ride comfort. It is to provide.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems and achieve the object, a vehicle seat device according to the present invention is a vehicle seat device having a reclining seat back, comprising a first seat. Back, a second seat back, and a third seat back disposed between the first and second seat backs.
A seat back, and a connecting means for connecting the third seat back to at least one of the first and second seat backs and reclining with the one of the seat backs.

Preferably, the connecting means includes first connecting means for connecting a third seat back to the first seat back, and second connecting means for connecting a third seat back to the second seat back. The third seat back is reclined in conjunction with the reclining side of the first and second seat backs.

Preferably, the third seat back is divided so as to be reclineable independently of the first and second seat backs.

[0009] Preferably, the third seat back is provided with an armrest which can be protruded and retracted on a seat cushion.

Preferably, the third seat back is divided in a vehicle width direction, and the divided portions on the first seat back side and the second seat back side are interlocked with the first seat back and the second seat back, respectively. And each of the divided portions can be independently reclined.

[0011]

As described above, according to the first aspect of the present invention, the seat back is divided into the first to third seat backs, and the third seat back between the first and second seat backs is divided into the first and second seat backs. And by reclining with at least one of the second seat backs and reclining together with the one seat back, it is possible to secure a large area of the other seat back even when one of the seat backs is tilted down and reclined. And the ride comfort can be improved.

According to the second aspect of the present invention, the connecting means includes a first connecting means for connecting the third seat back to the first seat back and a second connecting means for connecting the third seat back to the second seat back. And the third seat back includes the first seat back.
Of the second seat back, the reclining is performed in conjunction with the reclining side, so that even when one of the seat backs is tilted down and reclined, the area of the other seat back can be secured and the back can be held easily. To improve the riding comfort.

According to the third aspect of the present invention, the third seat back is divided so as to be reclineable independently of the first and second seat backs, so that the third seat back is provided between the first and second seat backs. A space open at the top can be formed, and long and tall luggage can be stored.

According to the fourth aspect of the present invention, since the third seat back is provided with the armrest which can be protruded and retracted on the seat cushion, the riding comfort can be improved by the armrest.

According to the fifth aspect of the invention, the third seat back is divided in the vehicle width direction, and the first seat back side and the second seat back side are divided.
The divided portions on the seatback side can be reclined in conjunction with the first and second seatbacks, respectively, and each divided portion can be reclined independently, so that the seat can be adjusted according to the size of the luggage or the occupant. The degree of freedom in selecting the back area increases.
