Description

[Detailed Description of the Invention] Technical Field The present invention provides a seat cushion that is supported so as to be rotatable between a use position that is located almost horizontally and supports the buttocks of a seated person and a storage position that is in an upright position. The present invention relates to a jump seat for a truck, which is provided with a seat back that supports the back of a seated person, and is arranged in a space between a seat in a vehicle interior and a back panel at the rear of the vehicle interior.

PRIOR ART In order to make effective use of the space between the seat and the back panel, it has been well known to provide a jump seat of the type described above in the space. When the jump seat is not in use, the seat cushion can be rotated to the upright storage position to expand the space behind the seat and allow luggage to be loaded therein.

However, with this configuration alone, the top surface of the pedestal that supports the seat cushion is located far above the floor panel of the vehicle body, so when the seat cushion is rotated to the retracted position, the top surface of the pedestal and There will be a large step between it and the floor panel.
This makes it difficult to place cargo here in a stable manner.

Therefore, the seat cushion was divided into two parts, one of which was placed in an upright storage position, and the other was folded down into the gap between the seat cushion pedestal and the seat so that its top surface was flush with the top surface of the pedestal. A flat surface with a shape of
For this reason, a jump seat has been proposed that allows large items to be loaded in a stable manner (see Japanese Utility Model Application Publication No. 157936/1983).

This jump seat can be said to be an excellent and highly practical seat that provides stability for loaded cargo and does not impair the seat cushion's original function of seating.

However, with this configuration, the seat cushion must be divided into two parts, which increases the total number of parts, complicates the structure, and increases cost. Since the gap between the seat and the base is narrow, in order to cover this space with the seat cushion, the seat cushion must be divided into two parts. Furthermore, when the two seat cushions are used by placing them on a base, if the seat cushions are split into two, there is also the problem that sitting comfort is reduced.

In addition, various automobile seats have been proposed in which the seat bag can be rotated to the area in front of the seat cushion and luggage can be loaded in the space above the seat bag and the seat cushion. The structure is complex and the cost is high.
Moreover, it has the disadvantage of not being able to secure a large cargo loading space.

Purpose The purpose of the present invention is to eliminate all of the above-mentioned drawbacks of the conventional method, to ensure a large cargo loading space in the space behind the seat when the jump seat is not in use, and to have a simple structure, low cost, and a reduced number of parts. To provide a jump seat which can reduce the number of passengers and does not reduce seating comfort during use.

Configuration In order to achieve the above object, the present invention provides a jump seat that is arranged in a space between a seat in a vehicle interior and a back panel at the rear of the vehicle interior, and is held in a position facing the back panel. , a seat back that supports the back of a seated person; a stay that protrudes from one end surface of the seat back; and a stay attached to the back panel that locks the stay of the seat back that is inserted from below to position the seat back in a position facing the back panel. a pedestal having an upper surface located above a front panel constituting the floor surface of the vehicle body; The seat back is positioned almost horizontally on the upper surface of the pedestal and supports the buttocks of the seated person, and the seat back is separated from the back panel and stands up facing the back panel, or is placed on the side of the passenger compartment. A seat cushion is rotatably supported between a storage position that stands up opposite a side wall, and a stay of a seat bag that is attached to the base and inserted from the front is locked, and the upper surface of the seat bag is locked. and a second seat back support means that holds the seat bag in front of the pedestal so that the stay and the top surface of the pedestal are substantially flush with each other, and that allows the stay to be removed forward by releasing the lock. We propose a jump sheet consisting of:

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Figure 1 is a perspective view showing the interior of the truck;
The figure is a partially sectional side view of the vehicle, and two sets of jump seats 3, 3a are arranged in the space between the seat 1 shown in FIG. 2 and the back panel 2 at the rear of the vehicle compartment. Since these jump sheets 3 and 3a have the same structure, only one jump sheet 3 and its related structure will be explained below.

The jump seat 3 includes a base 6 having an upper surface 13 (FIG. 3) located above a floor panel 7 that constitutes the floor surface of the vehicle body, and a seat cushion 4.
and a seat bag 5, and FIGS. 1 and 2 show these in the use position where they are used as a seat. At this time, the seat cushion 4 is positioned substantially horizontally on the upper surface of the base 6. The sea bag 5 is supported by the back panel 2 while being held in a position facing the panel 2. In this state, the seat cushion 4 can support the buttocks of a seated person (not shown), and the seat back 5 can support the back of the seated person.

The illustrated pedestal 6 includes a seat riser 8 fixed to a floor panel 7 of the vehicle body, and a lid 1 supported by the riser 8 and a support bracket 9 of the back panel 2.
0, and a seat cushion 4 is placed on the upper surface of the lid 10 and the seat riser 8. Lid 10
The inside can be used as a storage space.

The seat cushion 4 has a frame 11 pivotally attached to the back panel 2 via a hinge device 12, and when the jump seat 3 is not in use, the seat cushion 4 can be moved with the seat back 5 separated from the back panel 2 as described later. 4 can be rotated in the direction of arrow A and placed in the upright storage position facing the back panel 2, as shown in FIG.

As mentioned above, the seat cushion 4 is supported so as to be rotatable between the use position shown in FIG. 2 and the storage position shown in FIG. Therefore, the upper surface 13 of the pedestal 6
can be exposed and cargo can be loaded here. However, if the baggage is to be placed only on this top surface 13, the pedestal 6 protrudes upward from the floor panel 7, as explained earlier, so that a large baggage that extends from the pedestal 6 to the seat 1 can be placed in a stable state. It cannot be loaded.

Therefore, in the jump seat 3 according to the present invention, the seat back 5 supported by the back panel 2 as shown in FIGS. It is held forward, and the upper surface 13 of the base 6 and the upper surface 15 of the seat bag 5 are substantially flush with each other, so that even large items 14 can be loaded therein in a stable manner.

According to this configuration, there is no need to divide the seat cushion 4 into two parts as in the conventional case, and it is therefore possible to reduce the number of parts, simplify the structure, and reduce costs. In addition, when the seat cushion 4 is placed on the pedestal 6 as shown in FIGS. 1 and 2, and the seated person places his or her buttocks on it, the seat cushion 4 is not divided into two parts, so the seat cushion 4 is not divided into two parts, so the seat cushion 4 is not divided into two parts. will not decrease.

Moreover, as shown in FIG. 3, the upper surface 13 of the pedestal 6
Since the luggage 14 is loaded on the upper surface 15 of the seat bag 5 which is almost flush with this, a large luggage space can be secured. Like conventionally proposed seats, the seat cushion is placed on the base,
If a seat cushion is placed in front of the seat cushion, and the upper surfaces of both are flush, and the cargo is loaded there, the upper surfaces of the seat cushions will be located higher than the top surface of the pedestal, so there will be no space for cargo loading. The space is too narrow to carry large items.
With the configuration according to the present invention, such drawbacks can be eliminated.

Seat cushion 4 also occupied an unused position.
is located opposite the back panel 2 as shown in FIG. If the seat cushion 4 is rotated to the non-use position while the seat bag 5 is held in the position shown in Figure 2, the seat cushion will move forward (to the right in Figure 3) by the thickness of the seat bag 5. ), the cargo loading space is narrowed, but the configuration according to the present invention can reliably eliminate this drawback.

Next, a specific example of the structure of the support means for detachably supporting the seat back 5 with respect to the back panel 2 and the base 6 will be explained.

FIG. 4 is an enlarged sectional view of the seat back 5 when it is supported by the back panel 2, and 16 is a back window fixed to the back panel 2;

A lock hole 26 that can be aligned with the center hole 21 of
are mated. As a result, lock plate 2
5 can be slid in the left-right direction by an amount corresponding to the length of the elongated hole 27, and the plate 25 can be prevented from coming off from the slit 24. Furthermore, as shown in FIG. 6, the holder 20
A compression coil spring 30 is inserted into the guide hole 29 formed in the lock plate 25, and this spring 30 presses and biases a knob 31 fixed to the lock plate 25.

On the other hand, the seat bag 5 is fixedly provided with a stay 32 protruding from one end surface thereof, and when the seat bag 5 is supported by the back panel 2 as shown in FIG. It is fitted into the center hole 21 of the holder 20 of No. 20. At this time, the notch 33 formed in the stay 32 engages with the lock plate 25, and this engagement is supported by the biasing force of the spring 36. Therefore, the stay 32 is supported by the holder 20, and the seat back 5 is eventually supported immovably by the back panel 2.

To remove the seat bag 5 from the back panel 2, push the knob 31 of the lock plate 25 in the direction shown by arrow B in FIG. All you have to do is release it and pull the stay 32 downward from the holder 20. On the contrary, holder 20
When the stay 32 is inserted into the center hole 21 from below, the notch 33 and the lock plate 25 are automatically engaged by the action of the spring 30, and the seat back 5 is supported by the back panel 2.

Although the number of holders 20 and stays 32 can be set as appropriate, in the illustrated example, two of each are provided.

The above-mentioned reinforcing member 18, support bracket 19,
The holder 20, the lock plate 25, the compression coil spring 30, and the knob 31 constitute an example of first seat back support means attached to the back panel 2, and this support means constitutes one component of the jump seat 3. As mentioned above,
Stay 32 of seat bag 5 inserted from below
is locked to hold the seat bag 5 in a position facing the back panel 2, and by releasing the lock, the stay 32 is allowed to come out downward.

On the other hand, as shown in FIG. 7, a pair of support brackets 119 similar to the above-mentioned support bracket 19 are also fixed to the seat riser 8 of the base 6, and to these a pair of holders 120, which are completely similar to the above-mentioned holder 20, are fixed.
is fixedly supported, and the holder 120 has an opening toward the outside at the end of the center hole of the holder on the side where the lock plate (not shown; see FIG. 5) is provided.

Therefore, the stay 32 of the seat bag 5 removed from the back panel 2 is placed in the holder 120 on the side of the base 6.
If you insert it from the front into the center hole of holder 2,
Just as in case 0, the notch 33 of the stay 32 is engaged with the lock plate of the holder 120, that is, locked, and the seat back 5 can be held in front of the base 6. By pressing a knob (not shown) on the holder 120, the above-mentioned lock can be released, the seat back 5 can be removed from the pedestal 6 in the forward direction, and it can be attached to the back panel 2 again.

The above-mentioned bracket 119, holder 120, its lock plate, knob, etc. constitute an example of the second seat back support means attached to the base 6, and this support means also constitutes one component of the jump seat 3. Then, as described above, the stay 32 of the seat bag 5 inserted from the front is locked, the upper surface 15 of the seat bag 5 and the upper surface 13 of the pedestal 6 are brought into a substantially flush state, and the seat bag 5 is moved from the front of the pedestal 6. By releasing the lock, the stay 32 is allowed to come out forward.

In the above embodiment, the seat cushion is stored in an upright position on the side facing the back panel. It can also be supported rotatably between the ivy storage position and the ivy storage position.

The configuration of the holder and stay described above is basically the same as that often used as a support device for supporting the headrest on the seat of general automobiles, and is described in, for example, Japanese Utility Model Publication No. 51-24664. Details are disclosed.

Effects According to the present invention, luggage can be stably loaded in the space behind the jump seat when the jump seat is not in use.

Furthermore, when attaching or detaching the seat bag to or from the back panel or pedestal, it is only necessary to insert or remove the stay protruding from the seat bag into the first or second support means, and the operation is extremely simple. can be simplified.

Furthermore, the seat cushion is rotated to an unused position facing the back panel or side wall, widening the top surface of the pedestal, and in front of it, the seat back is placed flush with the top surface of the pedestal to create a cargo loading space. Because of this, a larger cargo loading space can be secured than before, and large cargo can be loaded.

In addition, the stay of the seat back is inserted upward into the first seat back support means, and is removed by lowering it downward, so when the seat back is held on the back panel side, the first seat back support means , will be located above the seat back. Therefore, by removing this seat back from the back panel, the seat cushion can be reliably rotated to the non-use position facing the back panel without interfering with the first seat back support means, and a large It is possible to secure cargo loading space.
