Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in the structure of a lower portion of a rear seat cushion of an automobile and a rear floor to which the rear seat cushion is attached.

[0002]

2. Description of the Related Art FIG. 4 shows a structure near a rear floor 1 of a conventional automobile. A rear seat cushion (hereinafter referred to as a seat cushion) 2 is mounted on the rear floor 1. A fuel tank 3 is located in the lower center of the rear floor 1.
Is arranged. Further, suspension members 4 are arranged on both lower sides of the rear floor 1. In order to secure the capacity of the fuel tank 3, the central portion 1a of the rear floor should be formed at a position as high as possible. However, in order to improve the ability of the suspension,
It is necessary to position the suspension member 4 as low as possible and to place the actuation shaft 6 of the trailing arm 5 in a low position. (By the way, in FIG. 4, 7 is a shock absorber, 8 is a suspension spring, and 9 is an axle.) For this reason, it is preferable that both side portions 1b of the rear floor are formed low. For the above reasons, the rear floor 1
Requires a shape having a height difference between the central portion 1a and both side portions 1b as shown in FIG.

In order to fix the seat cushion 2 on the rear floor 1 having this height difference, the thickness of the cushion is changed between the cushion central portion 2a and the cushion both sides 2b as shown in FIG. It was in close contact with both the part 1a and both sides 1b. Further, as shown in FIG. 7, the cushion central portion 2a is closely attached to the rear floor central portion 1a, and the tip portions of both side portions 1b of the rear floor are
A form in which the spacer 10 is attached to fill the height difference was also used. In this case, the spacer 10 was also used as a strength member for the vehicle body.

[0004]

However, the conventional structure has the following drawbacks. In the form shown in FIG. 6, the thickness necessary for the seat cushion 2 to exert sufficient cushioning properties is sufficient if the thickness of the central portion 2a is sufficient, and the thickness of both side portions 2b is excessive. there were.
In addition, the difference in cushion thickness between the central portion 2a and both side portions 2b causes unevenness in sitting comfort, which causes discomfort.

Further, in the type using the spacer 5 as shown in FIG. 7, since the spacer 10 supports only the tips of the cushion both side portions 2b, the center of the both cushion side portions 2b is not supported. It sank and made me feel uncomfortable. Also, both of the above formats
The space formed by the height difference between the rear floor central portion 1a and both side portions 1b (the space below the cushion both side portions 2b) has not been effectively used.

The present invention has been made in view of the above problems, and an object of the present invention is to effectively use the space generated by the difference in height of the rear floor and to improve the sitting comfort of the rear seat.

[0007]

Means for Solving the Problems According to the present invention for solving the above problems, a rear seat cushion divided into three parts for a center and both sides is arranged on a rear floor where both side parts are formed in a low position. The side cushion has a vertical rotation shaft at the rear end and a frame at the bottom, and the rear floor has a stepped portion on which the frame below the side cushion can be placed. Characterize.

In the present invention, it is desirable that the tray is detachably arranged in the space formed between the upper surfaces of both sides of the rear floor and the side cushion frame placed on the stepped portion.

[0009]

The rear seat cushion is divided into three parts, and the side cushion having the frame at the lower part can be opened and closed with the rear end as an axis. The rear floor is provided with a step portion for mounting the cushion frame at a predetermined distance from the upper surfaces of both side portions of the rear floor. All the load received by the side cushion is temporarily supported by the lower frame, and the lower frame is supported by the step portion, so that unnecessary deformation of the side cushion is eliminated. Further, the thickness of the center cushion and the side cushions is made uniform, and the space between the side cushions and the upper surfaces of both side portions of the rear floor is used as a tray placement location.

[0010]

The present invention will be described below with reference to the drawings. In the figure, the same or corresponding parts as those of the conventional example are indicated by the same reference numerals,
Detailed explanation is omitted.

1 and 2 show an embodiment of the present invention. 1 and 2 show a structure near a rear floor 1 of an automobile (a two-door vehicle, a three-door vehicle, etc.) having no door beside the rear seat. In the rear floor 1, the central portion 1a is formed high in order to secure the capacity of the fuel tank 3 provided below. Further, since the pivot shaft 6 of the trailing arm 5 needs to be placed in the low position (see FIG. 4), the rear floor both side portions (only one side is shown) 1b are formed low in order to place the suspension member 4 in the low position. Has been done.

Therefore, the rear seat cushion has a three-part structure composed of the center cushion 11 and the side cushions 12 corresponding to the positions where the height difference of the rear floor 1 occurs. Here, the center cushion 11 and the side cushion 12 have the same thickness. Similarly to the conventional seat cushion 2 (see FIGS. 6 and 7), the center cushion 11 is fixed in close contact with the rear floor central portion 1a. The side cushion 12 can be opened and closed up and down about a rotary shaft 13 provided at the rear. Further, a pipe frame 14 is formed in a frame shape at the lower portion of the side cushion 12 so that the load of the cushion 12 can be uniformly received.

On the rear floor 1, side cushions 12 are provided.
Is formed into a stepped portion 15 (hatched portion) on which the pipe frame 14 can be placed. Further, the striker 16 is attached to the pipe frame 14 so as to face downward, and the lock mechanism 17 of the striker 16 is installed on the step portion 15, so that when the side cushion is closed,
I try not to open it carelessly.

Further, a tray 18 having a shape capable of being stored in a space S formed between the upper surfaces of both sides 1b of the rear floor and the side cushion 12 in the closed state is provided. The tray 18 is removable by opening the side cushion 12, and is fixed inside the space S when the side cushion 12 is closed.

The pipe frame 14 formed under the side cushion 12 once supports all the load received by the side cushion, and is placed on the step portion 15 to transmit the load to the rear floor 1. Therefore, the side cushion 12 is unnecessary. There is no deformation or partial depression, and the sitting comfort is even. Further, since the side cushion 12 is formed to have the same thickness as the center cushion 11, there is no difference in sitting comfort from the center cushion, and the side cushion 12 is a comfortable rear seat cushion as a whole.

Further, the pipe frame 14 provided at the lower portion of the side cushion 12 receives the force when a shock is applied to the vehicle body from the lateral direction, and the rigidity of the vehicle body can be further improved. Furthermore, the space S below the side cushion 12 that has not been effectively used in the past can be used as a storage space, thereby enhancing the commercial value of the automobile.

FIG. 3 shows a case where the present invention is applied to an automobile having a door beside a rear seat (four-door, five-door car, etc.).
Shown in. In the case of a 4-door vehicle, the corner 1 of the side cushion 12 'should be set so as not to impair the ease of getting on and off from the rear door.
It is necessary to chamfer 2'c. Therefore, the pipe frame 14 'and the tray 18' are formed according to this chamfered shape. Other parts are the above-mentioned 3,
Since the structure is the same as that of the four-door vehicle, the detailed description is omitted.

[0018]

As described above, the present invention has the following effects. The tray can be arranged in a space formed by the height difference between the central portion of the rear floor and both side portions (a space below both side portions of the cushion) to be used as a storage space.

The pipe frame formed under the side cushion of the rear seat cushion divided into three parts is
Since the side cushion is placed on the step portion 15 and supports the entire side cushion evenly, a part of the side cushion does not sink and the sitting comfort is even. Further, since the center cushion and the side cushions are formed to have the same thickness, there is no difference in sitting comfort between the center cushion and the side cushions, and the rear seat cushion is comfortable as a whole as a whole. Moreover, the pipe frame below the side cushion also functions as a strength member of the vehicle body.

Further, the rear seat cushion of the three-part structure can be used for other models by changing the combination, and the parts cost can be reduced.
