BACKGROUND OF THE INVENTION
The present invention relates to a vehicle seat device, and more particularly, to a seat device that can seat three people.
[0002]
[Background Art and Problems to be Solved by the Invention]
Conventionally, as a vehicle seat apparatus for three seats, a so-called bench seat provided with a seat cushion having a width for three seats and a seat back, a seat cushion having a width for one seat, and a seat for one person having a seat back And a seat apparatus called a 1.5-divided seat divided into a seat cushion having a width for two persons and a seat for two persons in a seat back, and a seat cushion having a width for one person and a seat back A seat device in which three seats for one person are arranged is known.
[0003]
In terms of sitting comfort and freedom of seat arrangement, a seat device with three seats for one person is the best, but if there is a restriction on the width of the passenger compartment, it is possible to secure a sufficient width for each seat for one person. difficult. Thus, when the width | variety of each one-person seat cannot fully be ensured, it will become difficult to obtain favorable seating comfort. In addition, the position of the center of the seat for one person on both the left and right sides tends to be away from the center of the vehicle, and these seating positions are close to the doors and windows on the side of the vehicle. However, there was a problem that it was difficult to obtain a good sitting comfort.
[0004]
Therefore, in order to solve the above-mentioned problem, the applicant of the present application first sets the width of the central seat that is less frequently used to be smaller than the left and right seats that are frequently used, and as a seat belt device for the center seat. A first seat belt device having a tongue and a buckle engageable and disengageable with the tongue, and a second seat belt device similarly having a tongue and a buckle engageable and disengageable with the tongue The first seat belt device is provided with one of the tongue and the buckle attached to the left side of the central seat and the other at the position near the vehicle center of the right seat, and the second seat belt device. Proposed a vehicle seat device in which one of a tongue and a buckle is attached to the right side of the central seat and the other is provided at a position near the vehicle center of the left seat.
[0005]
In the vehicle seat device proposed earlier, the center seat is narrowed to a small width that cannot be used alone, so that the left and right seats that are frequently used have sufficient width as the width even if the vehicle width is limited. If the center seat is also used, it can be seated even with a small width by using it side by side with the left and right seats, and the seat belt device for the center seat straddles both the left and right seats. By providing two sets of seat belt devices, the first seat belt device and the second seat belt device, the seat belt can be secured with a sufficient width even when the central seat is used side by side with either the left or right seat. It was characterized by being able to wear the device.
[0006]
However, in the vehicle seat device proposed previously, two sets of seat belt devices for the central seat are provided, and when one of the two sets of seat belt devices is used, the other is not used. Since the buckle and tongue of the seat belt device remain mounted on the seat cushion of the central seat, there is a risk of giving a sense of protrusion to the seated person.
The buckle or tongue of the seat belt device attached to the central seat may hang down to the side of the seat cushion when not in use. In this case, when the left and right seats are slid, In this case, it is necessary to slide the seat in order to take out the buckle and tongue that are sandwiched between them, and it has been desired to improve usability.
[0007]
The present invention has been made paying attention to this conventional problem, to secure a good seating comfort by securing the seat width on the left and right outer sides, which are frequently used, and to ensure a high degree of freedom of seat arrangement. The seat belt device for a vehicle capable of setting the seat belt device for three persons is provided, and the seat belt device for the central seat gives a sense of protrusion to the seated person. It is an object of the present invention to improve the vehicle seat device by preventing the seat belt device from being sandwiched between adjacent seats.
[0008]

In this case, a tongue or buckle attached to the right side of the central seat is paired with this. The other side of the tongue or the buckle provided at a position near the center of the left seat is engaged.
[0013]
As described above, in the present invention, the other of the tongue or the buckle that is paired with one of the tongue and the buckle provided on the left and right of the central seat is provided on the right seat and the left seat outside the center seat. Therefore, even if the center seat itself does not have a sufficient width, the seat belt device can be provided to the occupant seated in the center seat.
[0014]
Further, in the central seat, the seat belt device that is not used in the first and second seat belt devices stores the buckle or tongue provided in the central seat in the recess in the rear portion of the seat cushion.
Therefore, when seated on the central seat, the buckle or tongue of the seat belt device in a non-use state does not give a sense of protrusion. In addition, when a seated person sits on the buckle or tongue housed in the recess, a cushioning material is provided at the lower part of the recess, so the buckle or tongue housed in the recess is It sinks by the amount of deformation and does not give a sense of protrusion or foreign body to the seated person. Furthermore, since the buckle or tongue provided in the central seat is hidden in the recess, the appearance can be improved.
[0015]
Further, when the first and second seat belt devices are stored in the recess when not in use, the seat belt device does not hang down on the side of the central seat, and the central seat and the left and right seats are relatively moved. When it is slid, the buckle or tongue of the seat belt device is not caught between the seats, and the usability can be improved.
[0016]
Furthermore, in the invention according to claim 2, the buckle and tongue of the seat belt device are taken in and out of the recess while deforming the skin from the opening. In this case, since the skin is the skin of the seat cushion and has flexibility, it can be easily put in and out with a small opening area.
In addition, when the buckle or tongue is stored in the recess, the buckle or tongue is hidden to improve the appearance, and further, when seated on the central seat, the seat belt device buckle or tongue is difficult to touch directly to the seated person. It makes it harder to feel the protrusion.
[0017]
In the invention according to claim 3, the central seat is provided with only the tongue or the buckle only on the left and right, and the buckle or the tongue that is paired with the tongue is provided on the right seat and the left seat.
Accordingly, since the tongues provided on the left and right sides or the buckles cannot be engaged with each other in the central seat, the central seat alone cannot be seated on the seat belt device. Therefore, the single use of the center seat can be prevented.
