DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an auxiliary seat provided on the side of the driver's cab of a motor vehicle, particularly a parcel delivery motor vehicle.

Recently, the service industry called courier service, which delivers parcels etc. to companies, homes, etc., has been expanding. The delivery vehicle used for this delivery is required to have several special functions due to its purpose. For this reason, delivery vehicles such as those shown in FIGS. 1 and 2, for example, have been designed. That is, the interior of the delivery vehicle 1 is divided into a driver's cabin 5 and a luggage compartment 6 by a partition wall 3 on the rear side of the driver's seat 2 and a partition door 4 that is slidable in the vehicle width direction. Further, the right door 7 on the side of the driver's seat 2 slides along the outer surface of the vehicle body 8, while the left door 9 on the opposite side slides along the outer surface of the vehicle body 8.
is adapted to slide into a recess 10 formed on the outer surface of the vehicle body 8. Furthermore, a double door opening/closing door 11 is provided at the rear of the luggage compartment 6.

In such a delivery vehicle 1, loading parcels for delivery into the cargo compartment 6 is done by opening the opening/closing door 11 at the rear of the vehicle body, but when delivering to each home, the driver The partition door 4 is opened and closed to take in and take out cargo, and the left door 9 is opened and closed to load and unload. (The reason why the right side door 7 is not used is because in Japan, people drive on the left side, so it is dangerous to go in and out on the right side, and also because the houses of delivery destinations are often on the left side.) For this reason, the driver is seated in the seat. Rather than getting on and off on the right side of seat 2,
Since many passengers board and exit vehicles on the left side, it is especially desirable that the left side of the driver's seat be easily accessible.

By the way, in many of these delivery vehicles, the parcels normally handled are relatively small, the driver can deliver by himself, and there is only one driver's seat.
In many cases, it is sufficient to carry one person, but depending on the baggage, an assistant may be required, and there are requests to provide an auxiliary seat. In this case, the auxiliary seat is usually installed to the left of the driver's seat, and when there is no assistant, that is, when the auxiliary seat is not in use, emphasis is placed on the ease of getting out of the seat on the left side of the driver's seat. ,
There is a desire to store the auxiliary seat in a position where it will not interfere with getting out of the seat as much as possible.

Regarding storing the auxiliary seat,
For example, as disclosed in Utility Model Publication No. 49-40100, there is an auxiliary seat for bus passenger seats in which the auxiliary seat is erected on the side of the main seat after the back seat is folded. However, when such an auxiliary seat is used in a delivery vehicle, when the auxiliary seat is raised to the side of the driver's seat, it is higher than the upper end of the auxiliary seat and the driver's seat, so it becomes a nuisance when leaving the seat. There is a problem with becoming.

In view of the above-mentioned problems, the present invention provides an auxiliary seat that is installed on the side of the driver's seat in a delivery vehicle or the like, and when not in use, can be raised on the driver's seat side and then lowered and stored in a low position. The purpose is to

In the auxiliary seat of the present invention, a support column is fixed to the floor next to the driver's seat, and a base is rotatably supported in the left and right direction of the driver's cabin by a rotating shaft provided at the top of the support column, and a slide mechanism is mounted on the base. A seat bottom is provided so as to be able to slide in the left and right direction of the driver's cabin through the seat, and the end of the seat back is rotatably supported so that it can be folded over the seat bottom. The seat bag is held in a horizontal use position, and when not in use, the locking means is released, the seat bag is folded over the seat bottom, and then rotated around the rotation axis to stand up on the driver's seat side.
Furthermore, the device is characterized in that it can be slid down by the slide mechanism and stored in a low position. Note that, due to the structure of the auxiliary seat, the locking means can be divided into means for preventing rotation of the base relative to the support column, and means for preventing sliding of the seat bottom relative to the base.
These may be combined into one means, or each means may be separate.

According to the present invention, when the auxiliary seat provided on the side of the driver's seat is not in use, it can be placed upright on the driver's seat side and then lowered and stored in a low position, so that the upper end of the auxiliary seat can be kept low. This significantly improves the ease of leaving the seat without obstructing the driver when leaving the seat during work (delivery), and the floor space occupied by the auxiliary seat is also reduced, saving floor space on the side of the driver's seat. It can be used widely and has many advantages, such as being able to take out the next delivery package from the cargo compartment and temporarily store it there. That is, according to the present invention, it is possible to provide an auxiliary seat for carrying an assistant along, and to prevent the driver from leaving the seat due to the auxiliary seat.
And the pressure on the space to the side of the driver's seat can be minimized. The auxiliary seat position when raising the auxiliary seat to the side of the driver's seat and lowering it downwards is as follows.
It is best for the upper end of the auxiliary seat to be lower than the driver's seat; however, there may be cases where it cannot be lower than the driver's seat due to structural reasons or seat dimensions/position, and even in such cases, it should be made as low as possible. It is desirable to keep it low. Note that in this specification, all directions such as front and rear, left and right, etc. are expressed with the driver sitting in the driver's seat. That is, the direction in which the vehicle is traveling is the front, and the left and right sides in the direction of travel are shown as left and right.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 3 is a sectional plan view of an automobile equipped with an auxiliary seat according to the present invention, and is the same as the example of the automobile shown in FIG. 2 except that it is equipped with an auxiliary seat 12, and the same parts are Numbers are given and explanations are omitted. As shown in this figure, the auxiliary sheet 12
is provided on the left side of the driver's seat 2, and when the driver opens and closes the partition door 4 to put in and take out luggage, or when the driver opens and closes the left door 9 to get on and off, the Since you often sit down, work efficiency can be greatly improved if you keep the auxiliary seat out of the way.

4 to 9 show examples of the auxiliary seat according to the present invention, in which FIG. 4 is a front view, FIG. 5 is a right side view, and FIGS. 6, 7, and 8 are The sectional view and FIG. 9 are perspective views. Examples of the auxiliary sheet according to the present invention will be described below using these drawings.

As shown in FIGS. 4 and 5, a column 21 is fixed to the floor 20 next to the driver's seat, and a cylindrical body 21a extending in the front-rear direction is fixed to the upper part of the column 21. As shown in FIGS. A shaft 22 is rotatably inserted into this cylindrical body 21a to constitute a rotating shaft. However, the cylindrical body 21a is provided with a groove 21b extending in the circumferential direction as shown in FIG.
The shaft 22 inserted into this cylindrical body 21a through 1b
This restricts the rotation of the shaft 22 relative to the cylindrical body 21a, and prevents movement in the axial direction. It goes without saying that a pin or the like may be used instead of the bolt 30. Furthermore, both ends of the shaft 22 are fixed to the base 23, which is shown in FIG.
As shown in the cross-sectional view taken along the
Insert the shaft 22 into the hole, and insert the pins 23b and 23 into the hole coaxially penetrating the bush 23a and the shaft 22 in the radial direction.
b is press-fitted to fix the shaft 22 to the base 23. Therefore, the base 23 is rotatable with respect to the support 21 in the left and right directions around the shaft 22 and within the range in which the bolt 30 can move together with the shaft 22 in the groove 21b provided in the cylinder 21a (indicated by arrow B in the figure). ).

As shown in FIG. 7 (a partial cross-sectional view of only the base part taken along the line - in FIG. 4), the upper surface of the base 23 has two parallel angles 23c extending in the left-right direction. 23c are fixedly installed, two roller shafts 23d are provided at right angles to each angle 23c and at equal intervals, and two rollers 23e are rotatably provided on each of the shafts 23d.
In addition, two U-shaped rails 24b, 24b extending in the left-right direction and parallel to each other are fixedly installed on the lower surface of the seat frame 24, which integrally forms the seat bottom with the cushion 24a placed on the upper surface. The open portions of the rails 24b, 24b are fixed so as to face forward in the rail placed on the front side, and toward the rear in the rail placed on the rear side. On the other hand, the roller 23e
is attached so as to protrude rearward at the angle 23c provided on the front side, and is attached so as to protrude forward at the rear angle 23c. Therefore, by fitting the rollers 23e to the U-shaped rails 24b, the base 23 moves the seat frame 24 in the left-right direction (as indicated by the arrow C in FIG. 8, which shows a cross section along the line - in FIG. 7). Direction) It is supported so that it can slide freely. That is, the U-shaped rail 24b and the rollers 23e constitute a sliding mechanism. In addition,
The above configuration is for holding the seat frame 24 slidably in the left and right directions with respect to the base 23, and from this point of view, the number of rollers is not limited to four, and the mounting of the rails and rollers may be reversed. That is, a rail may be provided on the base 23 and a roller may be provided on the seat frame 24. Furthermore, the seat frame 24 may be made to slide with respect to the base 23. For example, base 23
A groove extending left and right may be provided in the seat frame 24, and a convex portion provided on the seat frame 24 may be fitted into the groove and slid along the groove.

In addition, the seat back 25 has one end connected to the seat frame 2.
It is rotatably supported in the front-rear direction (in the direction shown by arrow A in the figure) by a support shaft 26 provided at the rear of 4, and is in the operating position shown by the solid line (from this point onward, it is located at one of the locking means). It is prevented from falling over by a stopper 25a), and can be folded forward to overlap with the cushion 24a (indicated by a two-dot chain line in the figure).

Furthermore, a stay 27 for holding the seat bottom consisting of the cushion 24a and the seat frame 24 in a substantially horizontal use position is rotatable at one end by a stay shaft 29 provided at the bottom of the seat frame 24. It is supported, and the other end is received by a stay receiver 21c fixed to the side of the support column 21. (See Fig. 8) In order to prevent the stay 27 received by the stay receiver 21c from coming off, the hook 27a fixed to the end of the stay 27 is pulled downward by a locking tool 28 as a locking means. It is tension-locked. The purpose of this stay 27 is to hold the seat bottom in an almost horizontal use position. For example, instead of the stay, the groove position shown in FIG. It may be stopped by the bolt 30 hitting it. However, in this case, it is necessary to separately provide a locking means to prevent the seat bottom from rotating around the shaft 22.

However, the seat bottom (seat frame 24
Since the entire structure (consisting of the seat frame 24a and the cushion 24a) can slide on the base 23 while rotating around the shaft 22 and is unstable, it can be used as a removable locking means to prevent the seat frame 24 from moving relative to the base 23. Blocking means (not shown), e.g. base 23
The screw means etc. for tightening the seat frame 24 together with the seat frame frame 2
4 is provided.

Furthermore, a handle 24c is fixed to the side of the seat frame 24 to facilitate storage of the auxiliary seat.

In the auxiliary seat configured as described above, when the auxiliary seat is used, the stay 27 locked by the locking tool 28 prevents the rotation shown by the arrow B about the shaft 22, and also prevents the above-mentioned prevention. Seat frame 2 relative to base 23 by means (not shown)
4 and hold the seat bottom in a substantially horizontal use position, and move the seat back 25 in the direction of arrow A.
It can be raised in the direction shown by and held in a substantially vertical use position determined by the stopper 25a, and can be provided as an auxiliary seat for an assistant or the like. When the auxiliary seat is not used, after folding the seat back 25 over the seat bottom cushion 24a (operation in the direction of arrow A), the locking tool 28 and the movement preventing means between the base 23 and the seat frame 24 are removed. Release the seat, rotate the base 23, seat bottom, and seat back 25 together around the shaft 22 toward the driver's seat (located on the right side of the auxiliary seat) to stand up (operation in the direction of arrow B), and then remove the base. By sliding the seat frame 24 relative to the seat frame 23, the seat bottom and seat back are pushed down as one (operation in the direction of arrow C);
It can be stored.

As explained above, according to the present invention, when the auxiliary seat provided on the side of the driver's seat is not in use, it can be raised up on the driver's seat side and lowered to be stored in a low position. becomes lower,
The auxiliary seat is less of a hindrance to the driver, allowing them to leave and leave the seat smoothly, and the space to the side of the driver's seat is larger than when the auxiliary seat is fixed, improving the efficiency of delivery operations. .
