In addition, in such a conventional structure, the rear side of the seat back 53 serving as a cargo bed is covered with garnish or the like to prevent dirt, but there is a sense of resistance when loading a heavily soiled or angular object. There is also dissatisfaction from.

The present invention has been made in view of the above problems. An object of the present invention is to provide a vehicle rear seat that eliminates the above problems and has a relatively simple structure and an optimum luggage space. Still other objects will be sequentially clarified in the contents described below.

[0006]

According to the present invention, as shown in FIGS. 1 and 2, a rear seat 1 comprises a seat cushion 2 and a seat back 3.
In a rear seat for an automobile, which is separated from a luggage compartment 14 provided on the back side by the seat back 3, the seat cushion 2 is rotatable in a standing direction with the front side as a fulcrum relative to the floor surface 21a side. The seat back 3 is provided so as to be rotatable in a vertical direction with an upper side as a fulcrum with respect to a corresponding portion of the vehicle body, and a lower side is provided. The rear end of the seat cushion 2 is connected via a hinge 4 so that the seat cushion 2 can be lifted to a substantially horizontal state with the upper side as a fulcrum in conjunction with the turning operation of the seat cushion 2 in the upright direction. Chamber 14 is seat cushion 2
, And is enlarged in accordance with the rising movement of the seat back 3 and the lifting movement of the seat back 3.

In this structure, when a long load or a large amount of load is to be placed, the seat cushion 2 is rotated in the upright direction in which the rear side is used as a front fulcrum. Then, the seat back 3 is lifted while being rotated as an upper fulcrum via the hinge portion 4 in conjunction with the rotation of the seat cushion 2. This state is maintained by the holding means 11. The luggage compartment 14 is communicated with the rear portion of the vehicle compartment 15 by the upright seat cushion 2 and the seat back 3 raised to a substantially horizontal state, and is greatly enlarged. In addition, the expanded luggage compartment portion includes the seat cushion 2 in the upright state and the seat back 3 in the substantially horizontal state.
And is separated from the front side of the cabin 15. Therefore, the present invention can be applied to a case where the luggage compartment 14 is expanded even if the luggage compartment 14 is enlarged.
Since the space between the front side and the front side is partitioned, the safety and appearance are superior to those of the conventional structure shown in FIGS. 3 and 4, and at the same time, the risk of the sheet itself being soiled or damaged by luggage is eliminated.

The present invention is more preferably embodied as follows. First, the holding means 11 is interposed between the lower surface side of the seat cushion 2 and the floor surface 21a side, and is constituted by a damper mechanism which urges the seat cushion 2 in a direction to be erected as a front fulcrum. . In this structure, in addition to the original function of the holding means 11 supporting the seat cushion 2 in the upright state, the seat cushion 2 can be operated with a small force when the seat cushion 2 is rotated to the upright state, and the switching operability of the seat cushion 2 is improved. Can be improved. Second
In addition, the seat cushion 2 has a lock means 8 provided on the rear side and engaged with and disengaged from the floor surface 21a side, and a pull cord 10 which is rotated about the front side in the upright direction. is there. This structure is necessary for the locking means 8 to reliably maintain the seat cushion 2 itself in the used state and for the drawstring 10 to rotate the seat cushion 2. In this case, it is more preferable that the drawstring 10 can also be used for unlocking the lock means 8 from the viewpoint of operability.

[0009]

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. The embodiments described below are preferred specific examples and have various technically preferred limitations, but do not limit the technical scope of the present invention.

FIGS. 1 and 2 show the main parts of an automobile to which the present invention is applied. FIG. 1 schematically shows a state where a luggage compartment is enlarged, and FIG. 2 schematically shows a normal state before the luggage compartment is enlarged. Is shown. 1 and 2, the rear structure of the vehicle has a rear seat 1 disposed thereon and a luggage compartment 14 on the rear side thereof.
Is located. The rear seat 1 has a seat cushion 2
And the seat back 3, and is separated from the cargo room 14 by the seat back 3. The luggage compartment 14 has a seat back 3
Is a vertical wall member, and the tonneau board 5 located behind the seat back 3 and disposed substantially horizontally above is used as a horizontal wall member.
Each is partitioned from the vehicle compartment 15. The tonneau board 5 is held by brackets (not shown) provided on both inner sides of the vehicle body. However, a tonneau cover may be used instead.

The most different point from the related art is that the seat cushion 2 and the seat back 3 are connected by a hinge portion 4. That is, the two members are connected to the connecting member 4 b protruding from the rear end side of the seat cushion 2.
A connecting member 4c protruding from the lower end of the seat back 3 is rotatably connected by a pivot 4a. The connecting members 4b and 4c are fixed to a frame (not shown) of the seat cushion 2 or the seat back 3, respectively. Here, the seat back 3 is installed at a fixed position in the vehicle compartment 15 in a state where the upper end side is supported by a bracket 6 a provided on both inner sides of the vehicle body via a pivot 6 b so as to be rotatable clockwise. The chamber 14 is partitioned. When the seat back 3 is pivotally operated in a direction of lifting the lower side with the hinge 6 composed of the bracket 6a and the pivot 6b as a fulcrum, the relative position with respect to the seat cushion 2 is reversed via the pivot 4a. That is, the mode can be switched between the modes shown in FIGS.

On the other hand, the front side of the seat cushion 2 is rotatably connected to the floor surface 21a on the vehicle cabin 15 side via the hinge bracket 7 and the pivot 7a, and the rear side is a part in FIG. It is disengaged via the lock means 8 as shown in a partially enlarged manner. A gas damper 11 is a holding means for urging and supporting the seat cushion 2 in an upright state.
have. Of these, the hinge bracket 7 is provided so as to protrude from the floor surface 21a on the vehicle cabin 15 side. Axis 7a
Is fixed to the upper part of the hinge bracket 7 and its front end side is fitted in a long hole 2a provided on the corresponding side of the seat cushion 2 in a state where it cannot be removed. Although details of the long hole 2a are omitted, a guide plate with the long hole 2a is fixed to the frame of the seat cushion 2, and the portion is decorated with a resin product. Accordingly, in this structure, the front end side of the seat cushion 2 forms a hinge portion by fitting the pivot 7a and the elongated hole 2a, and the rear side of the seat cushion 2 is rotated upward through the hinge portion. It is structured so that it can be moved slightly in the front-rear direction when performing.

The locking means 8 is provided for the seat cushion 2.
Is provided at a substantially intermediate portion on the rear side, and is engaged with and disengaged from the striker 9 protruding from the floor surface 21a of the passenger compartment 15, and has a pull cord 10 for releasing the engagement. The structure is substantially the same as that described in Japanese Utility Model Laid-Open No. 2-108624, and as shown in FIG.
Is attached to a bracket 8a provided at the rear end of the seat cushion 2 via a pivot 8a in a state where it is urged in a locking direction by an urging means (not shown). The tip of the drawstring 10 is connected to a member. The drawstring 10 is the seat cushion 2
From the rear end to the holding surface side. Therefore,
When the seat cushion 2 is placed in the normal horizontal state in FIG. 2, the locking means 8 moves over the striker 9 while elastically displacing the locking means 8a. Restored to locked state.
To release the locked state, the drawstring 10 is pulled against the spring pressure of the urging means. Then, the claw-shaped member, which is the locking means 8, is rotated to the unlocked position as shown by the one-dot chain line in the enlarged view. Such a lock means 8 is convenient because the same pulling cord 10 can be used to perform the operation of engaging and disengaging the striker 9 and the operation of rotating the seat section 2 in the upright direction. However, the present invention is not limited to this structure, and a general lock means and drawstring may be used.

The gas damper 11 comprises a damper mechanism for expanding and contracting the rod 11a by gas pressure, and is disposed between the rear side of the lower surface of the seat cushion 2 and the front side of the floor surface 21a corresponding to the seat cushion 2. . The case base end side of the gas damper 11 is rotatably supported via a pivot 12a with respect to a bracket 12b fixed to a floor surface 21a of the vehicle body 21. The protruding end of the rod 11b is rotatably supported via a pivot 13a on a bracket 13b fixed to the rear of the lower surface of the seat cushion 2. The gas damper 11 is mounted on the bracket 1
A force is always applied in a direction separating the hinge portion 12 composed of the pivot 2a and the pivot 12a and the hinge portion 13 composed of the bracket 13a and the pivot 13b.

Next, the operation of the rear seat 1 will be outlined. FIG. 2 shows a seat mode used as a normal rear seat 1. In this embodiment, the locking means 8 is in the locked state, and at the same time, the rear seat 1 and the vehicle body 21 or the vehicle body 21 are urged by the spring pressure of the gas damper 11 biasing the hinge part 12 and the hinge part 13 away from each other. The play between the floor surface 21 and the floor surface 21 is removed.

When it is desired to use the luggage compartment 14 with a large expansion, the pull cord 10 is first pulled strongly in the direction of the arrow in FIG. Then, the engagement between the locking means 8 and the striker 9 is released, and the rear of the seat cushion 2 and the lower side of the seat back 3 are rotated while the hinge 6, the hinges 12 and 13, and the hinge 4 rotate. The seat cushion 2 and the seat back 3 are pivoted upward while both are pulled forward in the passenger compartment 15. Finally, as shown in FIG. 1, the seat cushion 2 is tilted to the front side and rises, and the seat back 3 is in a substantially horizontal state above the seat cushion 2, and the luggage compartment is expanded inside the cabin 15. 14 are formed. In this state, a "bulk room enlargement mode" in which large luggage can be loaded or a large amount of luggage can be loaded is achieved.
Further, in this structure, when the seat cushion 2 and the seat back 3 are pivoted while being lifted upward, the force from the gas damper 11 is applied through the seat cushion 2, so that the seat cushion 2 and the seat back 3 are applied with a light force. Can be rotated upward. Further, after the rotation, the state after the rotation, that is, “the luggage compartment enlargement mode” is also generated by the pushing force generated by the gas damper 11.
Is held. In the luggage compartment enlargement mode, the interior of the luggage compartment 14 is in an expanded state, but is separated from the outside by the seat cushion 2 and the seat back 3 as before the enlargement.

When returning from the above-described "enlargement mode" to the "normal mode" in FIG. 2, for example, the seat cushion 2 is pushed in a direction of falling down. Then, both the seat cushion 2 and the seat back 3 are pivoted downward while receiving the damper action of the gas damper 11, and the locking means 8 is engaged with the striker 9 at the final position to return to the "normal mode". Therefore,
In such a rear seat 1 for an automobile, the operation can be switched between the normal mode and the luggage room expansion mode with relatively simple and weak force, and the luggage room 14 can be expanded as necessary. Thereby, the luggage compartment 14 can be easily enlarged,
A large object or a large amount of luggage can be stored in the expanded luggage compartment 14. Also, luggage room 1
Even in a mode in which 4 is enlarged, the baggage in the luggage compartment 14 can be kept invisible from the outside because it is covered with the seat back 3 and the seat cushion 2, and the appearance is improved. Can be done. In addition, compared to the conventional trunk-through system, it is possible to load luggage without worrying about dirt on the seat itself.

The present invention relates to the above embodiment,
Although the example in which the gas damper 11 is used as the holding means for holding at the position of the "package expanding mode" has been described, the invention is not limited thereto, and a simpler one such as a mechanical spring means may be used. The above embodiment is an example of a bench seat, but may be a separate type.

[0019]

As described above, the rear seat of the present invention has the following effects. As the luggage compartment enlargement structure, the seat cushion is set upright with the front side as a fulcrum, and the seat back is lifted in a substantially horizontal state with the upper side as a fulcrum. , The cabin is more widely available. From the viewpoint of livability, in the state where the luggage compartment is enlarged, the seat back acts as the upper horizontal wall and the seat cushion acts as the front vertical wall, so that the luggage in the enlarged luggage compartment is not visible. For this reason, since luggage cannot be seen from the front seat side or the outside, it is possible to maintain indoor livability. From the viewpoint of usability, the switching operation only needs to be performed by rotating the seat cushion (the seat back is lifted in conjunction with the seat cushion), and since the luggage is placed on the floor surface, the user is concerned about the dirt on the seat as in the past. It is excellent in that luggage can be loaded without any problems.
