[Prior art]
Conventionally, the above-mentioned seat device with an auxiliary seat for automobiles is disclosed in Japanese Utility Model Publication No. 58-29528.
[0003]
According to the above publication, a main seat and an auxiliary seat are arranged on the passenger compartment floor so as to line up with the main seat in the width direction of the main seat, and each of these seats has a seat cushion and a seat cushion. And a “vertical posture” seat back that protrudes upward from the rear end side. The auxiliary seat is provided with a pivoting tool for pivotally supporting the lower end portion of the auxiliary seat on the rear end portion of the seat cushion so that the seat back can be reciprocally rotated toward the front lower side.
[0004]
The seat back of the auxiliary seat can be superimposed on the seat cushion by its forward rotation, and the end side opposite to the main seat side in the width direction of the auxiliary seat in this “overlapping state” faces upward. A pivotal support is provided to pivot the end of the main seat on the main seat so that it can be reciprocated. The auxiliary seat in the “overlapping state” rotates forward until it is in the “standing position”. It is possible.
[0005]
Each seat cushion in each seat can be seated by an occupant from the front, and each seat back can seat an occupant seated on the seat cushion.
[0006]
On the other hand, when the auxiliary seat is not used, the upper surface of the seat back can be used as a small baggage stack if the auxiliary seat is brought into the “superposed state”.
[0007]
Further, if the auxiliary sheet in the “overlapping state” is set to the “standing posture”, the left-right width dimension of the auxiliary sheet is reduced, and the auxiliary sheet is displaced to the main sheet side. A passage is formed on the side opposite to the auxiliary seat, and the passage of the occupant in this passage can be smoothly performed without the interference of the auxiliary seat. Further, the upper end surface of the auxiliary seat in the “standing position” is used as an armrest for a passenger seated on the main seat.
[0008]
[Problems to be solved by the invention]
By the way, in the above conventional technique, in order to make the backrest of the auxiliary seat with respect to the seatback equivalent to that in the main seat, the upper end of the seatback in the “vertical posture” of the auxiliary seat is made higher, There has been proposed a technique in which the heights of the upper ends of both seat backs in the “vertical posture” are substantially the same.
[0009]
However, if the above is performed, the seat back becomes long. Therefore, when the auxiliary seat is set to the “overlapping state”, the rotation end of the seat back is at least one of the two seat cushions. It may protrude forward from the front end of the seat cushion, and in this case, the protruding portion of the seat back may interfere with the occupants who want to pass the front side of each seat in the width direction. It is not preferable.
[0010]
The present invention has been made paying attention to the circumstances as described above, and in the case where the backrest of the auxiliary seat arranged side by side with the main seat is as good as the main seat, When the auxiliary seat is not in use, when the seat back is rotated forward and overlapped with the seat cushion to be in an “overlapping state”, the occupant whose rotational end of the seat back tries to pass the front side of each seat The problem is to enable smooth traffic without disturbing the traffic.
[0011]

And the auxiliary seat pivotally supports the lower end of the auxiliary seat on the rear end of the seat cushion so that the seatback can be reciprocally turned toward the front and lower direction. The heights of the upper ends of both seat backs in the “vertical orientation” are substantially the same, and the seat back of the auxiliary seat can be superimposed on the seat cushion by its forward and backward rotation. A seat device with an auxiliary seat for an automobile in which the pivot end of the seat back projects forward from the front end of at least one of the two seat cushions. Stomach,
[0045]
The protruding portion of the seat back that protrudes forward from the front end of the one seat cushion in the “overlapping state” of the auxiliary seat is configured to be able to be detached and restored from the rotation center side portion of the seat back. .
[0046]
For this reason, when the auxiliary seat is in the “overlapping state”, if the protruding portion of the seat back is separated from the portion on the rotation center side, the protruding portion causes the front passage of each seat to move left and right. It is possible to prevent the passengers who are going to pass and prevent smooth passage.
[0047]
That is, as described above, the height of the upper end of the “vertical orientation” seat back of the auxiliary seat arranged side by side on the main seat is positioned so as to be the same as that of the main seat, so that the seat back is good. Even when the backrest is secured, when the auxiliary seat is not in use, when the seat back is rotated forward and overlapped with the seat cushion to be in an “overlapping state”, the rotational end portion of the seat back Is prevented from obstructing an occupant trying to pass through the front side of each of the above seats, and smooth passage can be achieved.
[0048]
Also, a pair of left and right main sheets are provided, the auxiliary sheet is installed between the two main sheets, and one end side in the width direction of the auxiliary sheet in the “overlapping state” moves forward and backward. When the auxiliary seat is set in the “standing posture” by the forward rotation, the auxiliary seat is displaced toward one of the main seats, and It is designed to be an armrest for the passenger seated on the main seat.
[0049]
For this reason, on the side of the auxiliary sheet opposite to the one main sheet, another path connected to the path in the front-rear direction is formed between the auxiliary sheet and the other main sheet. Passing in the front-rear direction of the occupant in the other passages can be performed smoothly without the auxiliary seat getting in the way. The auxiliary seat in the “standing position” is used as an armrest for a passenger seated on the one main seat.
[0050]
Further, the protruding portion can be supported on a side portion of the other main seat on the auxiliary seat side so that the protruding portion becomes an armrest of an occupant seated on the other main seat.
[0051]
For this reason, when the auxiliary sheet is not used, the auxiliary sheet is placed in an “overlapping state” and in a “standing position”, and the auxiliary sheet is used as an armrest for one main sheet, while the auxiliary sheet is used. If the protruding portion is separated from the rotation center side portion and supported by the other main seat, the protruding portion is used as an armrest for the other main seat.
[0052]
Therefore, not only is it unnecessary to store the protruding portion that has become useless after being detached from the rotation center side portion, but it is beneficial because this protruding portion is used. .
