Description

[Detailed Description of the Invention] This invention relates to a rear seat device for an automobile that allows the seat back of the rear seat to be reclined rearward.

BACKGROUND OF THE INVENTION It is common practice to configure the seat back of a front seat of an automobile to be reclinable, thereby allowing a front seat occupant to obtain a seating position according to his or her preference, thereby improving comfort. In recent years, there has been an increasing demand for improved comfort for rear seat occupants, and a structure that allows the seat back to recline in the same way as the front seats has begun to be adopted for the rear seats. Because the vehicle body or other parts are located in the 6th
As shown in FIG. 7, the conventional structure has various drawbacks. The rear seat 30 in FIG. 6 has a seat cushion 31 attached to the vehicle floor 32 via a slide rail 33 so as to be freely movable back and forth. By moving the seat cushion 31 forward, the seat back 3
4 is configured to be reclined rearward to the state shown by the imaginary line X.

However, in the above configuration, by moving the seat cushion 31 forward, that is, to the front seat side (not shown), the distance between the seat cushion 31 and the front seat becomes narrower, the leg space is reduced, and seating comfort for the occupant is deteriorated. There is a drawback.

On the other hand, in the rear seat 30 shown in FIG. 7, a seat cushion 31 is fixed to the vehicle floor 32, and a bellows-shaped seat cushion 36 is provided between the seat back 34 and the rear package tray 36 provided on the upper front surface of the rear package 35. A flexible member 37 is interposed, and the lower end of the seat back 34 is connected to the recliner 3.
It is configured to be attached to the vehicle body floor 32 via 8. Therefore, the seat back 34 can be reclined backwards as shown by the imaginary line X by operating the recliner 38 without moving the seat cushion 31 forward. There is a drawback that the length is shortened by the length l necessary for interposing the flexible member 37, and the effective area becomes small.

Incidentally, Japanese Utility Model Application No. 56-98740 discloses a seat in which the seat back is divided into upper and lower parts so that the angle of the seat back corresponding to the back and lumbar region of the occupant can be varied. As with the seat shown in FIG. 6, it has the disadvantage that the leg space is small.

Further, Japanese Patent Laid-Open No. 56-34310 discloses a seat in which a headrest is rotatably attached to the upper end of the seat back. This device had a structure as shown in FIG. 7, and had the above-mentioned drawbacks.

This invention was made in view of the above-mentioned conventional drawbacks, and it is possible to recline the seat back of an automobile without moving the seat cushion forward and without reducing the effective area of the package tray. The purpose is to provide a rear seat device.

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

FIG. 1 shows a perspective view of the entire rear seat to which this invention is applied, and FIG. 2 shows a side view of this invention to which the invention is applied to a forward-folding type rear seat. In these figures, the rear seat 1 consists of a seat cushion 2 and a seat back 3. The seat cushion 2 is fixed to the vehicle floor 4, and the seat back 3 is attached to a seat back frame 5 which is wider than the seat back 3. It is attached via a recliner 6. The lower end of the seat back frame 5 is rotatably attached to a bracket 7 fixed to the vehicle floor 4 via a pin 8. For this purpose, the seat bag 3 is folded forward as shown by the imaginary line A in FIG. 2 and superimposed on the seat cushion 2 by the operation described below.

Reference numeral 9 designates a head rest, whose central portion is rotatably attached via a pin 11 to a bracket 10 fixed to the upper end of the seat back frame 5, and whose lower end is attached to the upper end of the seat back frame 3 via a pin 12. are rotatably connected.

A rear package 13 is provided behind the rear seat 1 and has an opening 14 at the front thereof.
The upper end, that is, the front lower edge 15a of the rear package tray 15 provided on the upper front surface of the rear package 13 is set to be somewhat higher than the height position of the upper end of the seat back 3.

A locking member 16 for holding the seatback frame 5 in an upright position is rotatably provided at the rear of the upper end of the seatback frame 5, and this locking member 16 is attached to the upper surface of the rear package tray 15. It is removably engaged with a locking claw 17 located therein. In the figure, 18 indicates a cushion body.

In the above configuration, the locking member 16 is connected to the locking claw 17.
By, for example, pulling up the operating lever 6a of the recliner 6 while the seatback 3 is engaged with the seatback frame 5, the seatback 3 is no longer interfered with by the seatback frame 5 and can be rotated about the pin 8, for example. When the occupant presses the seat back 3 backward with his or her back, the seat back 3 is rotated rearward about the pin 8, and the right seat back 3 in FIG. 1 is moved as shown by the imaginary line B in FIG. A reclining state in which the rear package 13 is inserted can be obtained. At the same time, the pin 12 of the connecting portion between the seat bag 3 and the head rest 9 moves rearward, so the lower end of the head rest 9 pivots rearward about the pin 11, and the right head rest 9 in FIG. 1 and the right head rest 9 in FIG. The state shown by the virtual line C is reached. In this case, no step is formed between the front upper end of the seat bag 3 and the front lower end of the headrest 9, and they are smoothly continuous, resulting in a good appearance and not causing pain to the neck of the occupant. In addition, seat back 3
When returning the headrest 9 from the reclined state to the normal upright state, as in the past, this is done by pulling up the operating lever 6a of the recliner 6 and releasing the rearward pressure on the seat back 3. Ru.

The seat back 3 can be folded forward by disengaging the locking member 16 and the locking pawl 17 and then pulling up the operating lever 6a of the recliner 6. The rear package cage 13 communicates with the passenger compartment to expand the storage space for luggage.

FIG. 3 shows an example in which this invention is applied to a rear seat with a fixed seat back. It is rotatably attached to a fixed bracket 10. With this configuration, when the operating lever 6a of the recliner 6 is pulled up, the seat back 3 is reclined as shown by the imaginary line B and the headrest 9 is rotated as shown by the imaginary line C, as in the above embodiment. can be done.

FIG. 4 shows a side view of another embodiment of this invention applied to a forward-folding rear seat.
