Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a seat device for a wagon type automobile having three rows of seats.

(Prior Art) In this type of wagon type automobile, it is known that the seat cushion and seat back of the rear seat are held upright to form a large cargo room behind the center seat (for example, , see Utility Model Application Publication No. 58-80332). However, in this case, it is not possible to satisfy the demand for moving and deforming the rear seat to form a cargo room and effectively utilizing the rear seat as a part of the seat device. Also known is a vehicle in which a center seat and a rear seat are movable along a curved rail (for example, see Japanese Utility Model Publication No. 118134/1983). However, in this case, although it is possible to form a flat mat surface on both seats, it is not possible to satisfy the demand for the rear seat to be used for both forward-facing and rear-facing seats. In recent years, there has been a particular demand for diversification of the usage of automobile seats as described above.

(Purpose of the invention) The present invention was made to solve the above problems, and its purpose is to make it possible to create a half-bed between the center seat and the rear seat, and to make the rear seat available in two types: a forward-facing seat and a rear-facing seat. The purpose is to make it usable in various ways.

(Structure of the invention) The present invention includes a front seat placed on a front floor at the front of a vehicle interior, a seat cushion placed on a rear floor behind the front floor, and a seat cushion connected to the seat cushion through a reclining member. In an automobile equipped with a center seat and a rear seat consisting of a tiltably mounted seat back, guide rails for guiding the rear seat in the longitudinal direction are provided in the rear tire houses on both sides of the rear floor, and the guide rails include the a first holding part that positions and holds the seat cushion of the rear seat below the seatback when the seatback of the center seat is tilted backward; and a second holding part that is located behind the first holding part and holds the seat cushion of the rear seat in a rearwardly upright state. When the center seat is tilted back, the rear seat is moved forward to secure cargo room space behind the rear seat, and the center seat and rear seat can be made into a half-bed. The feature is that it can be moved rearward and used as a rear-facing seat.

(Embodiment) Hereinafter, an automobile seat device according to an embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows a schematic diagram of a wagon-type automobile with three rows of seats. and the rear floor 4 behind the front floor 2
A center seat 5 and a rear seat 6 are placed thereon.

The center seat 5 and the rear seat 6 have seat cushions 5a and 6a on which passengers sit.
and seat backs 5b and 6b, which are attached to the seat cushions 5a and 6a via reclining members 7 and 8 so as to be tiltable rearward, respectively, and serve as backrests for the occupant.

Seat cushion 5a of the center seat 5
is horizontally slidable in the front-rear direction with respect to a slide member 9 fixed to the rear floor 4.

On both sides of the lower surface of the seat cushion 6a of the rear seat 6, there are a pair of guide rollers 10, 1 in the front and rear.
0, 10, and 10 are provided (see FIGS. 5 and 6).

On the other hand, the guide rollers 10,
10 and cross-sectional guide rails 12, 12 for guiding them are provided. In other words, the rear seat 6 is guided by the guide rails 12, 12, and is configured to move in a circular arc trajectory in the front-rear direction. Reference numeral 13 is a seat frame.

Also, on both sides of the seat cushion 6a of the rear seat 6, there are lock pins 14 that position and hold the seat cushion 6a in a predetermined position.
It is attached so that it can rotate freely in an arc relative to 3. The lock pin 14 can be freely engaged with and detached from three lock holes 15, 16, and 17 formed in the side wall of the guide rail 12. Code 18 is lock pin 1
4 is an operating lever for rotating operation (see Fig. 7).

The lock hole 15 is bored in the center of the guide rail 12, and is used to hold the rear seat 6 in the position where it is used as the original rear seat.

The lock hole 16 is bored in the front side of the guide rail 12, and is used to hold the seat cushion 6a of the rear seat 6 in a position below the seat back 5b of the center seat 5 when tilting backward (as shown by the chain line in FIG. 2). It acts as a first holding part.

The lock hole 17 is bored on the rear side of the guide rail 12, and functions as a second holding portion for holding the seat cushion 6a of the rear seat 6 in an upright rearward state (shown by chain lines in FIG. 3).

Furthermore, a lock stay 19 is rotatably attached to the lower surface of the seat cushion 6a of the rear seat 6 to hold the rear seat 6 in an upright state (as shown by the chain line in FIG. 4). There is. When the lock stay 19 is not in use, it is stored in a state in which it is engaged with a locking tool 20 protruding from the lower surface of the seat cushion 6a. Reference numeral 21 indicates a notch hole for removing the rear guide roller 10 from the guide rail 12 when the rear seat 6 is upright.

However, the seat cushion 6 of the rear seat 6
A is moved forward along the guide rail 12 with the lock pin 14 unlocked,
Place the center seat 5 under the rearwardly tilted seat back 5b, and insert the lock pin 14 into the lock hole 16.
When engaged, the rear seat back 6b
At the same time, a cargo room space is formed behind the seat cushion 5a of the center seat 5.
A half bed is formed in which the seat back 5b of the rear seat 6 serves as a seating surface, and the seat back 6b of the rear seat 6 serves as a backrest surface (as shown by chain lines in FIG. 2).

Also, with the seat cushion 6a of the rear seat 6 unlocked by the lock pin 14, move it rearward along the guide rail 12, and engage the lock pin 14 with the lock hole 17 so that the seat is in the rearward standing position. When held, the rear seat 6 forms a rear-facing seat with the seat back 6b serving as a seating surface and the seat cushion 6a serving as a backrest surface (as shown by chain lines in FIG. 4). in this case,
The rear seat 6 can be used as a leisure seat for fishing and the like.

Furthermore, in the case of this embodiment, when a large cargo room space is desired at the rear of the vehicle cabin, the seat cushion 6a of the rear seat 6 is moved forward along the guide rail 12, as shown by the chain line in FIG. , the seat cushion 6a and the seat back 6b may be brought into an upright state by pivoting forward in an arc around the front guide roller 10. In addition, at this time, the seat cushion 6a is attached to the lock stay 19.
The posture is maintained by engaging the lock hole 16.

(Effects of the invention) As mentioned above, according to the invention, if necessary,
The seat cushion of the rear seat can be moved forward and backward along the guide rail provided in the rear tire house, and when moving forward, a cargo room space is created behind the rear seat back, and at the same time, the seat cushion of the center seat and the rear tilting While the half-bed can be configured with the seat back used as a seating surface and the rear seat back used as a backrest surface, when moving backwards,
Since the rear seat can be configured as a rear-facing seat with the seat back as the seating surface and the seat cushion as the backrest surface, the center seat and rear seat can be used effectively, resulting in the practical effect of making multifaceted use of the interior space of the vehicle. There is.

In addition, it is possible to use the seat in a wide variety of ways, such as half-bed and rear-facing seats, thereby satisfying the user's demands for diversifying the manner in which the seat is used.
