Description

[Detailed description of the invention] [Technical field] This invention relates to two-person seats for vehicles, and more specifically, this invention utilizes the back of the seat back of the seat located in the front row of a vehicle equipped with two or more rows of seats in the front and rear. This is a facing seat for a vehicle that allows left and right seated people in the same row to sit facing each other, and is applicable not only to buses, wagons, and railway vehicles, but also to general passenger cars.

[Prior art]

Ordinary two-row seats are used in wagons and other vehicles with three or more rows of seats, where the second row of seats rotates, allowing the person seated in the third row to seat the person seated in the third row, and the second row of seats to rotate. It is normal for the seated person to sit opposite the seated person. Such a seating system must include a mechanism for rotating and locking the second row of seats, that is, a rotating mechanism. Therefore, the weight of such a rotating mechanism itself becomes heavy, which increases the overall weight of the vehicle and increases fuel consumption.In addition, since the rotating mechanism has a large number of parts, it takes time to assemble and increases material costs. This leads to an increase in costs, and furthermore, there are drawbacks such as troublesome rotation operations.

〔the purpose〕

This invention improves the seating system using rotating seats as described above, and provides a seating system for vehicles that can be applied to passenger cars with only two rows of seats in the front and back, has a simple mechanism, has excellent operability, and does not increase weight. The purpose is to

〔composition〕

In order to achieve the above object, this invention attaches a back plate to the back of the seat back of the front row seats, and attaches both upper ends of this back plate to the upper sides of the seat back so as to be rotatable, so as to position the seat back of the rear row seats. The seat back of the seat located in the rear row of the seat to which the back plate is attached can be tilted backward.

〔Example〕

Preferred embodiments of this invention will be described below with reference to the drawings.

In FIG. 1, a seat 1 consists of a seat cushion 2 and a seat bag 3.
A back plate 4 is attached to the back of the seat bag 3, and both upper ends of the back plate 4 are rotatably attached to both upper sides of the seat bag 3. To attach the back plate 4 to the seat bag 3,
As shown in FIG. 2, it is rotatably attached to a bracket 3B provided on a frame 3A of the seat bag 3. In this embodiment, the seat bag 3
The back surface of the device is not aesthetically treated, and the back plate 4 covers this untreated portion. That is, the back side of the seat back 3 in a normal vehicle seat is covered with a decorative plate called a garnish, but in this embodiment, the back plate 4 is used instead of the garnish. Of course, there is no problem in attaching the back plate 4 after providing the garnish.

A leaf spring 4A is attached to the back surface of the back plate 4, and an engagement member 3C provided on the frame 3A
The snap engagement of the leaf spring 4A ensures that the back plate 4 is housed in the seat bag 3 (see FIG. 3). Further, when the back plate 4 is rotated to serve as a backrest for a person sitting in the rear seat, a lock mechanism 5 as shown in FIG. 4 is provided to prevent the back plate 4 from returning after rotation. As this locking mechanism 5, for example, two locking mechanisms as shown in FIGS. 5 and 6 are used.
Book arm (first arm 5B/second arm 5D)
Rotatably connect each end of (rotation connection part b),
A stopper 5C is provided at the tip of the first arm 5B,
Similarly, a bracket 5A attached to the frame 3A is rotatably attached to the base end of the first arm 5B (rotating part a), and a bracket 5E attached to the back side of the back plate 4 is rotatably attached to the tip of the second arm. It is attached (rotating part c). Therefore, the first and second arms 5B, 5
When D is fully extended, the second arm 5D comes into contact with the stopper 5C as shown in FIG. Leaning back or even backboard 4
will not return. When the back plate 4 is stored in the seat bag 3 as shown in FIG. 3, the lock mechanism 5 is in a folded state as shown in FIG. As the locking mechanism 5, in addition to such a mechanism, a reclining mechanism for rotating the normal seat bag 3 may be provided in the rotating portion of the back plate 4, and various other known mechanisms may be employed.

The back plate 4 can be made of various synthetic resin materials, a U-shaped frame covered with soft polyurethane foam and a skin, wood materials, metal materials, and the like.

The back plate 4 configured in this way is attached to the back of the seat back 3 of the front seat of a passenger car equipped with two rows of seats in the front and rear as shown in FIG. can sit opposite each other.
At this time, the seat back 3 of the rear seat is configured so that it can be tilted backwards, and as shown in Fig. 7, the person who wants to sit opposite the person sitting in the rear seat on the right side is seated in the front passenger seat (left side of the front seat, in the case of a Japanese car). The user raises the back plate 4 provided on the seat back 3 of the passenger seat, leans against it, and places his/her legs on the seat back 3 that is reclined toward the rear of the rear seat.

〔effect〕

As explained above, this idea utilizes the back of the seat back of the seat located in the front row (not necessarily the front row) of a vehicle equipped with two or more rows of seats in the front and rear rows. This is a seat for a vehicle that allows two people to sit opposite each other, and a back plate is attached to the back of the seat back of the front row seats, and both upper ends of this back plate are rotatably attached to both sides of the upper part of the seat back, so that the seat back can be used as the seat back for the rear row seats. The seat back of the seat located in the rear row of the seat with the backboard attached can be tilted backwards, making it significantly lighter and cost-effective compared to installing a rotating seat. This not only makes it extremely easy to operate, but it also makes it possible for people sitting in the back row of the left and right seats to sit face-to-face in a regular passenger car, which was previously thought to be impossible.
