Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is a vehicle that can be effectively used by removing the partition between the passenger compartment (same as the passenger compartment) and the cargo compartment by bringing the seat back to the front side among the rear seats, and making the interior space one. This is related to the rear seat.
[0002]
[Prior art]
As a vehicle rear seat, if the seat back that divides the compartment between the compartment and the cargo compartment is tilted forward, the compartment between the compartment and the compartment is removed, and one large space can be secured and large luggage can be mounted. There are some packages that allow easy loading of luggage (hereinafter referred to as seat back-through for convenience). In addition, when a rear seat for a vehicle is provided with an armrest storage recess in a part of the seat back, and the armrest body stored in the storage recess is rotated forward and pulled out to the use position, the vehicle compartment and the load are passed through the storage recess. A so-called armrest through structure is also known, in which a room communicates and through which a thing can be taken in and out between a passenger compartment and a cargo compartment.
[0003]
[Problems to be solved by the invention]
However, in the conventional vehicle interior design, either the seat back through or the arm rest through is employed, and there is no one that combines both. For this reason, in the case of the seat back-through structure, even when the small articles placed in the cargo compartment are taken in and out from the passenger compartment side, it is necessary to knock down the entire seat back, which is very inconvenient. On the other hand, in the armrest through structure, articles that can be taken in and out are limited to the size of the storage recess, and excessively large items cannot be taken in and out, which is very inconvenient.
In addition, in the conventional armrest through structure, there is one in which a lid is provided together with the armrest body, but the lid is only devised from the viewpoint of protecting the armrest body. Moreover, the conventional lid is not stable when it is stacked on the armrest body because the armrest body is formed on the curved surface of the seat, for example, it becomes unstable when a long object is placed on the lid, etc. Lack of usability and luxury. Furthermore, the armrest body is mounted in the storage recess by various mounting structures, but it does not complicate the mounting structure of the armrest body, adding value by maintaining the stability of the mounting state and making it removable. I want to grant.
[0004]
The present invention aims to solve the above-described problems. Specifically, by combining the seat back-through and the armrest through, the convenience of the occupant is further improved, and the above-mentioned problems are relatively easily eliminated, and the vehicle rear seat is designed to be more user-friendly and upgraded. It is to be realized. Still other objects will become apparent in the following description.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a foldable vehicle rear seat in which a seat back is tumbled from a standing position onto a seat cushion or a floor surface.
An armrest body that is provided in a part of the seat back and is housed in a storage recess that penetrates back and forth, and a rear opening of the storage recess that is disposed in the storage recess together with the armrest body. And a lid that can be opened and closed in a substantially flush state, the armrest body and the lid being overlapped with each other, disposed between both opposing mounting portions on the lower fixed side of the storage recess, The attachment portions and the corresponding side surfaces are rotatably attached through engagement of engagement pins and shaft holes, and the lid protrudes to the front side facing the armrest body and A gap-absorbing abutment portion that can be held in close contact with the back surface of the armrest body, and a front side that is formed using the abutment portion and that faces the armrest body and has an entrance and exit, It is characterized in that the armrest body has a pocket for small parts that become available are exposed to the storage recess in a state of being pulled out from said storage recess.
[0006]
According to this structure, when the seat back is turned over substantially parallel to the seat cushion or the vehicle body floor surface, the interior of the vehicle compartment and the cargo compartment partitioned by the seat back are communicated, and the interior space becomes one, It can be used effectively as a seat back-through, and even in that case, the back of the seat back, including the lid, is flush with each other, so that the usability can be maintained.
Further, in a normal state where the seat back is erected, only the armrest main body can be used as an armrest if it is rotated to the front side with the engagement pin and the shaft hole fitted as a fulcrum and pulled out to the use position. Furthermore, when the lid is rotated forward with the engagement pin and shaft hole fitted as a fulcrum at the armrest body use position, the storage recess functions as an armrest through, and small items can be taken in and out through the communication hole by the storage recess. It can be carried out. Accordingly, the occupant operates the seat back, the armrest main body, and the lid, and selects various modes according to the application such as the size and amount of the target article, and the size and length of the load to be loaded. be able to.
[0007]
Moreover, a seat back rear surface by being held over the invention, the back of the armrest body through an elastic abutting portions lid since it has a butting portion for clearance absorption on the front side facing the armrest body flush of Ru reliably obtain the. That is, the conventional lid has a flat plate shape, and stable contact with the seat curved surface of the armrest main body cannot be obtained, and it is meaningful to improve the usability during seat back-through.
Moreover, the lid has a pocket for small parts that are I lifting the entrance to the front side. This is because the abutting part is set on the front side of the lid as a structure for filling the gap between the lid and the armrest body, and a pocket for storing accessories is provided using the abutting part. There is. This pocket is exposed to the storage recess when the armrest body is in the armrest use state, and is effectively utilized as a small case for a CD or the like. In this case, it is more preferable that a plurality of the pockets are formed as in the second aspect, and the pockets can be stored in a state where small items are sorted and arranged.
Further, the armrest body and the lid are arranged with a gap between the both attachment portions as in claim 3 and are attached to the members such as the engagement pins so as to be detachable by filling the gap. It is a structure which has a stopper and is attached from the said attachment part through this stopper so that attachment or detachment is possible. This is because when the armrest body and the lid are detached from the storage recess, the substantial size of the storage recess is increased by an amount corresponding to the thickness of the armrest body and the lid in the armrest through described above. Larger articles can be taken in and out through the storage recess. At the same time, in the seat back-through, it is possible to form a recess by a storage recess on the back surface of the seat back and to restrain an article or the like in the recess. In other words, this advantage is meaningful in that the selection mode according to the above-described application can be further expanded to further improve the convenience of the passenger. In this attachment / detachment configuration, the armrest main body and the lid are disposed between the opposing attachment portions of the seat back side storage recess, and the attachment pins and the corresponding side surfaces are fitted to the engagement pins and the shaft holes, respectively. It is a structure on the premise of maintaining the stability of the attachment state, the rotation operability, and the simplification of the attachment structure. Then, the mounting procedure is arranged between the mounting portions as shown in FIG. 9B with the armrest body and the lid engaging the shaft holes on one side with the mounting portion side engaging pins of the storage recess. Next, as shown in FIG. 9A, after the engagement pin on the other side surface is slightly moved in a direction to engage with the mounting portion side shaft hole, the stopper is a corresponding engagement pin (or guide pin) as shown in FIG. And the like are engaged with each other. The disengagement procedure is to pull out the stopper and release the engagement, and then allow the armrest body and the lid to move between the engagement pin and the shaft hole by play through the gap and to disengage the front armrest body from the mounting portion. Become.

The pocket 43 includes a first pocket 43a defined by a front wall and both side walls of the lid and a concave portion inside the abutting portion 35a, and a concave shape inside the inner partition wall and both side walls of the abutting portion 35a and the abutting portion 35b. And a second pocket 43b partitioned by a portion. Then, from the state shown in FIG. 7B, the occupant can take in and out the small items 44 such as CDs from the entrances on the upper side with respect to the pockets 43a and 43b.
[0018]
(Operation) Next, a method of using the above-described vehicle rear seat will be outlined together with operational features with reference to FIGS.
Normally, the seat back 3 is used in the standing position indicated by the circled numeral 1 in FIG. 2, and the armrest body 10 and the lid 35 are housed in the storage recess 4. In this state, the armrest body 10 is in close contact with the front side of the lid 35, and the doorways of the pockets 43a and 43b are closed. When the armrest body 10 is used in the normal state where the back half 3A is in the upright position, when the pull string 18 of the armrest body 10 is pulled, the armrest body 10 is engaged with the engagement pins 14 and 24 and the shaft hole 26. , 16 as a fulcrum and pulled out from the storage recess 4 onto the seat cushion 2 as shown in FIG. In this state, the lid 35 remains in the storage recess 4 and the interior of the luggage compartment 7 cannot be seen from the passenger compartment side. In the storage recess 4, the pockets 43 of the lid 35 are exposed in an open state, and the small items 44 can be taken in and out as described above. When the armrest body 10 is rotated in the reverse direction, it is housed again in the storage recess 4 as shown in FIG.
[0019]
When it is desired to use the storage recess 4 as an armrest through, the lid 35 is engaged with the engagement pin 14 as shown in each of FIGS. 8 and 9 in a state where the armrest body 10 is tilted on the seat cushion 2. , 24 as a fulcrum, the storage recess 4 is penetrated in the front-rear direction. Therefore, the vehicle interior and the interior of the cargo compartment 7 are communicated with each other through the opening of the storage recess 4, and a long object can be placed therethrough or articles can be taken in and out. In this case, since the lid 19 is closely held on the back surface of the armrest body 10 via the gap absorbing abutment portions 35a and 35b, the lid 19 is not inadvertently moved or unstable, and is ideal as a placement portion. It is in a state. In this armrest through state, as in the conventional structure, the effective height cannot be obtained largely because the heights of the armrest body 10 and the lid 35 are obstructed. Accordingly, when it is desired to secure a large height of the armrest through, the armrest body 10 is temporarily removed together with the lid 35 as shown in FIG. 5, and the armrest body 10 and the lid 35 are mounted again when not in use. Become.
[0020]
The above operations or modes will be described in relation to the armrest attaching / detaching structure. Normally, as described above, the stopper 41 is a pin of the engaging pin 24 (or the guide pin 25) on the bracket 20A side as shown in FIG. The armrest body 10 is inserted and engaged with the periphery to fill a gap between the bracket 20 </ b> A and the one side surface 10 a, the movement of the armrest body 10 in the left-right direction is restricted, and the attached state is maintained. When removing the armrest body 10 and the lid 35, as shown in each of FIGS. 8 and 9B, after pulling the string member 42 and releasing the engagement of the stopper 41, the armrest body 10 and the lid 35 are removed. As shown in FIG. 8 and FIG. 9 (c), it moves slightly and is removed from between the brackets 20A and 20B. FIG. 5 shows a state in which the armrest body 10 and the lid 35 are removed in this way. Further, when the armrest body 10 and the lid 35 are attached, the operation opposite to this, that is, the operation from the state shown in FIG. 9B to the state shown in FIG. 9A is performed. Therefore, in this structure, since the armrest main body 10 and the lid 35 are attached and detached collectively, it is excellent in usability.
[0021]
Next, seat back-through will be described. When the back half 3A is used in the standing position indicated by the circled numeral 1 in FIG. 2, when the unlocking knob 6a (the knob 6b in the case of the back half 3B) is picked and pulled upward, The engagement lock at the position D of 1 is released, whereby the shaft 5a (or 5b) can be rotated forward with the shaft 5a (or 5b) as a fulcrum, and can be brought down on the seat cushion 2. In this state, the back rear surface is substantially flush with the floor surface 7A of the luggage compartment 7, and the space in the passenger compartment can be expanded to place a relatively large object. In this case, the lid 35 closing the inside of the storage recess 4 is flush with the back surface of the back, and the armrest body 10 and the lid 35 are in close contact with each other as described above. Even if a heavy object is placed on the portion including the lid 35, there is no possibility that the lid 35 sinks into the storage recess 4 and a step is formed. As another advantage, when the seat back-through is made with the armrest body 10 and the lid 35 detached, only the portion corresponding to the storage recess 4 becomes concave, and it is possible to put the article in a constrained state. Become.
[0022]
The present invention only needs to have the technical elements of claim 1, and the details are variously deformed and developed. For example, in the structure of the above-described embodiment, the structure in which the seat back 3 is divided into the back halves 3A and 3B is disclosed, but a bench-type seat back may be used without being divided.
[0023]
【The invention's effect】
As described above, according to the vehicle rear seat of the present invention, when the seat back is tilted forward, the seat back through is achieved, and a large article or the like can be stably placed on the back surface including the lid. In a state where the seat back is erected, only the armrest body can be rotated forward and used as an armrest with the engagement portion of the engagement pin and the shaft hole as a fulcrum. In addition, when the armrest body is pulled out to the use position and the lid is rotated forward with the engaging pin and shaft hole fitting part as the fulcrum, it functions as an armrest through and loads through the storage recess. Small items can be taken in and out of the room. Therefore, according to the present invention, by combining the seat back through and the arm rest through, various modes can be selected according to the size, amount, etc. of the target article, and the size, length, etc. of the load to be loaded. . At the same time, the problems described in the above-mentioned problems are wiped out relatively easily to improve usability and to achieve higher quality.
