Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an improvement of an automobile rear seat device.

(Prior art) In the rear seat of a car, as often seen in light vans and hatchbacks, the seat back separates the passenger compartment from the trunk.By folding the seat back forward, the trunk There is one in which the back surface of the folded-forward seat bag can also be used as a cargo loading surface by substantially enlarging the seat bag. In such a rear seat, there is a risk that luggage placed on the seat bag in the forward folded position may slide on the seat bag and move significantly forward due to sudden braking, for example.

Therefore, in order to prevent the luggage from moving forward,
As shown in Japanese Utility Model Application Publication No. 53-40923, a guide bar for securing cargo is provided at the upper end of the back of the seat bag so that it can be raised and lowered, and when the back of the seat bag is used as a cargo loading surface, this guide bar must be installed. It has been proposed that the bag is in an upright position, and a guide bar in this upright position restricts the forward movement of the baggage.

(Problem that the invention aims to solve) By the way, recently, seat backs that partition the vehicle interior and the trunk room as described above are often designed to have a left-right split structure. Increasingly, only the seat bag is in the forward folded position (the other split seat bag is in the upright position), and luggage is placed only on the back surface of one of the split seat bags.

In this case, if only a guide bar is provided for each split seat bag, the baggage will shift laterally if only one split seat bag as described above is used. In other words, the guide bar raised from the split seat bag on one side in the forward-folded position and the front surface of the split seat bag on the other side in the upright position are quite far apart in the front-rear direction, and this large space separates In other words, the baggage moves from the center end in the vehicle width direction of one split seat bag in the forward folded position to the front side of the split seat bag in the upright position (lateral shift diagonally forward). Such a situation could easily occur.

Therefore, the purpose of the present invention is to prevent the forward movement of the luggage when the seat bag has a left-right split structure and luggage is placed on one side of the split seat bag with the seat bag folded forward. Needless to say, the object of the present invention is to provide a rear seat device for an automobile that can also prevent lateral displacement.

(Means and effects for solving the problem) In order to achieve the above-mentioned object, in the present invention, in order to prevent the luggage from moving forward, a seat is provided at the upper end of the back of at least one split seat bag. A guide bar is provided.

In addition, in order to prevent the cargo from shifting laterally,
Basically, an armrest that can be raised and folded is provided between the two split seat bags, that is, at the center end in the vehicle width direction. When the armrest is in the forward-folded position, the height of the armrest in the forward-folded position is set to be higher than the back surface of the split seat back on one side which is in the forward-folded position and has a guide bar. be. As a result, the center end in the vehicle width direction of the split seat back on one side that is in the forward folded position is covered by the armrest in the forward folded position. It will function as

The front end of the armrest is supported in a cantilevered manner as a free end, and in consideration of the fact that the lateral rigidity is relatively low, the armrest is supported by a guide bar provided on the back of the split seat back and a lock that is held on the armrest. Lateral reinforcement is performed using rods. Specifically, the locking rod is held in each armrest so as to be rotatable and freely withdrawn by a predetermined amount toward the front end of the armrest, and a locking portion is formed at the front end of the locking rod, while An engaging portion with which this locking portion is engaged is formed on a guide bar provided on the back surface of the split seat bag and located in an upright position. That is, with only the split seat back on one side in the forward position and the armrest in the forward position, the locking rod is pulled out from the armrest in the forward position, and the rotation of the locking rod is then utilized. Then, by locking the locking portion to the engaging portion of the guide bar, the armrest tip end side and the guide bar are connected in the vehicle width direction, and sufficient lateral rigidity of the armrest is ensured. That will happen.

(Embodiments) Examples of the present invention will be described below with reference to the attached drawings.

In FIG. 1, numeral 1 is a so-called hatchback-type automobile, and luggage 3 can be taken in and out of a trunk room A using a hatch door 2.

A rear seat B as shown in FIGS. 2 and 3 is provided on the floor of the trunk room A, that is, in front of the rear floor 4. The rear seat B is composed of a seat cushion 5 and a seat back 6. This seat back 6 is divided into two left and right split seat backs 7 and 8 at the middle portion in the vehicle width direction, and each of the split seat backs 7 and 8 can be independently positioned in the upright position shown in FIGS. 1 to 3. , and the forward folded position shown in FIG. 4 (FIG. 4 shows the case where only one side of the split seat bag 7 is folded forward). Of course, when both the split seat bags 7 and 8 are in an upright position, the trunk room A is separated from the vehicle interior C. In addition, when each split seat back 7, 8 is placed in the forward position, its back surface is
It is arranged to be almost flush with the rear floor 4.

At the upper end of the back of each split seat bag 7, 8,
As shown in FIG. 5, guide bars 9 are provided respectively. In this embodiment, the guide bar 9 includes a locking portion 9a that extends long in the vehicle width direction, and a pair of short leg portions 9b that are bent at approximately right angles from both ends of the locking portion 9a. , this leg 9b
The distal end portions of the seat bags 7 and 8 are rotatably connected to the frames (not shown) of each of the divided seat bags 7 and 8. As a result, the guide bar 9 can take a collapsed position as shown in FIG. 3 and an upright position as shown in FIGS. 4 and 5.

Further, an armrest storage recess 10 is formed at the end of each split seat bag 7, 8 on the split side, and each storage recess 10 is shaped to open to the front and split surfaces of the split seat bags 7, 8. . Corresponding to the position of such storage recess 10,
Each divided seat bag 7, 8 is provided with an armrest 11, respectively. That is, each armrest 11 is connected to the split seat bag (frame) 7 or 8 so as to be rotatable about an axis extending in the vehicle width direction while the base end side thereof is inserted into the storage recess 10. There is. As a result, each armrest 11 independently extends from the upright position shown by the solid line in FIG. 2 (the stored position in the storage recess 10) and toward the front as shown by the dashed line in FIG. It is designed to be able to take a forward position and a forward position. Armrest 1 of one of the split seat backs 7 or 8 in the upright position.
1 is in the forward-folded position, the height of the armrest 11 in the forward-folded position is higher than the back surface of the other split seat bag 7 or 8 in the forward-folded position.

As shown in FIGS. 4 and 5, each armrest 11 has an opening 12 opened at its front end surface.
are formed, and a locking rod 13 is housed and held in each opening 12. That is, as shown in FIG. 6, the frame 14 of the armrest 11 has a cylindrical shape, and a guide pipe 15 is welded to the upper part of the inner peripheral surface of the frame 14. 13a is rotatably and slidably penetrated therethrough. The distal end of the locking rod 13 is shaped as shown in FIG. 5, and the locking rod 13 has a storage position where it is completely stored within the armrest 11, and a front end that is pulled out from the front end of the armrest. A locking rod 13 is used to draw out more than a predetermined number of drawers.
A stopper portion 13b formed by bending the rear end portion is regulated by coming into contact with the base end surface of the guide pipe 15 (see FIG. 6).

The front end of the locking rod 13 has a connecting portion 13c extending perpendicularly to the axial direction of the guide pipe 15, and by bending the tip of the connecting portion 13c at a right angle, the main body portion 13a A locking portion 13d is formed that extends parallel to a plane perpendicular to . By welding a bottomed cylindrical body to the leg portion 9b of each guide bar 9 from the center side in the vehicle width direction, an engaging portion 9c having an engaging hole into which the locking portion 13d can be inserted is formed. It is formed. This engaging portion 9c is configured such that its engaging hole faces upward when the guide bar 9 is in the upright position.

Note that when the locking rod 13 is in the storage position, the lock member 16 provided inside the armrest 11
The connecting portion 13c is gripped (fitted) to the housing to securely hold the storage position.

Next, the operation of the above configuration will be explained.

First, when both the split seat bags 7 and 8 are used in the upright position, each guide bar 9 is placed in the reclined position (see Figures 1 and 3) so that it does not interfere with the luggage 3 being loaded into the trunk A. Ru. Also, in this state, each armrest 1
1 is used for the comfort of a passenger seated on the rear seat B, with both or any one of them folded forward (see FIG. 2).

In addition, large luggage 3 in the vehicle width direction and front/rear direction
When loading the vehicle, both the divided seat bags 7 and 8 may be placed in the forward position, thereby substantially expanding the trunk room A. At this time, the guide bars 9 of both the divided seat bags 7 and 8 are both placed in the upright position, and the forward movement of the luggage 3 is restricted.

Here, regarding the case where only one of the split seat bags 7 and 8, for example only the split seat bag 7, is placed in the forward folded position and the luggage 3 is placed on top of it, which is most intended in the present invention, FIG. As will be described in detail with reference to FIG. 5, such an embodiment is often performed when the luggage 3 is long in the front-rear direction and relatively short in the vehicle width direction.

In this case, the guide bar 9 of the split seat bag 7 in the forward folded position is set to the upright position, and the armrest 11 of the split seat bag 8 in the upright position is set to the forward folded position. Then, move the locking rod 13 to the fifth position.
As shown in the figure, after being pulled out from inside the armrest 11, it is rotated to engage its engaging portion 13d with the engaging portion 9c of the guide bar 9. In this state, the luggage 3 is placed on the split seat bag 7 which is in the forward folded position. In this placed state, the forward movement of the luggage 3 is restricted by the guide bar 9, and the armrest 11 restricts the luggage 3 from shifting laterally. And this armrest 11
Since the tip end side of the guide bar 9 is locked to the guide bar 9, even if it receives a large external force in the lateral direction from the load 3 during a sudden turn, it will be able to firmly hold the load 3 against this force. can. Of course, to return the locking rod 13 to its original storage position, the procedure described above may be reversed. Of course, if there is an occupant sitting on the split seat bag 8 in the upright position, the armrest 11 of the split seat bag 8 may be folded forward and used for comfort.

It should be noted that the case where the split seat bag 8 is used in the forward folded position and the split seat bag 7 is used in the upright position is similar to that described above, so a redundant explanation thereof will be omitted.

(Effects of the invention) As is clear from the above, the invention has the following effects:
Even if the seat back of the rear seat has a left-right split structure, and only one side is placed in the forward position and luggage is placed on top of it, it is possible to prevent the luggage from moving forward, or from shifting sideways. This is preferable in terms of the stable placement of luggage.

In addition, since the above-mentioned lateral shift is controlled by using the armrest provided between the two split seatbacks, the appearance is good, and the occupants seated in the rear seat can always use the armrest, ensuring the safety of the occupants. A favorable result can also be obtained in terms of points.

Furthermore, the front end of the armrest used to prevent the above-mentioned lateral slippage, that is, the side that is the free end with respect to the split seat back, is firmly reinforced in the lateral direction, thereby reliably preventing the above-mentioned lateral slippage. , it is also advantageous in terms of ensuring its durability.
