Description

[Detailed Description of the Invention] The present invention relates to an engine room inspection lid device. For example, in a cab-over type truck as shown in Fig. 1, the engine room 2 is located directly below the seat 1.
Furthermore, the seat 1 is placed on an opening/closing lid 3, and the opening/closing lid 3 can be freely opened and closed with the seat 1 placed thereon, with its rear end serving as a fulcrum P, in order to facilitate inspection of the engine, etc. It is becoming.

That is, when inspecting the inside of the engine room 2, the opening/closing cover 3 is opened.

By the way, such engine room inspection devices conventionally have the following problems.

Seat 1 is usually equipped with a seat longitudinal adjustment mechanism, allowing the occupant to select a seating position suitable for driving.
Assume that the longitudinal position of is set at a relatively forward position as shown in FIG. In this case, when the opening/closing lid 3 is rotated around the fulcrum P and lifted, the tip of the seat cushion 1a moves on an arc indicated by the reference numeral 5, so it interferes with the steering wheel 4 on the way. In this case, the seat back and forth adjustment mechanism (not shown) is activated as shown in FIG. The position where the tip of the seat cushion 1a no longer interferes with the steering wheel 4,
For example, it is necessary to move the sheet 1 backward until it moves along an arc indicated by the reference numeral 5'.

As mentioned above, in the conventional technology, when the seat 1 is set forward, the opening/closing lid 3 can be opened sufficiently only by moving the seat 1 backward in advance, which is extremely complicated in terms of operation. It is.

The present invention has been developed in view of the above-mentioned problem, and provides an engine room inspection device that can sufficiently open the opening/closing lid 3 without interfering with the steering wheel 4, regardless of the position of the seat 1 in the longitudinal direction. The purpose is to

Hereinafter, the present invention will be explained in detail with reference to Examples.

The engine room inspection device according to the present invention is characterized in that a fulcrum is provided at the rear end of the seat cushion to rotatably support the seat cushion with respect to the opening/closing lid.

The principle of the present invention will be explained with reference to FIG.

In the figure, when the opening/closing lid 3 is rotated about the fulcrum P, the seat 1 follows a circular arc 6 shown by a broken line, and is at a position where the tip of the seat cushion 1a interferes with the steering wheel 4.

Therefore, if a fulcrum O is provided at the rear end of the seat cushion 1a and the seat cushion 1a is set to be rotatable with respect to the opening/closing lid 3 around this fulcrum O, the tip of the seat cushion 1a will be Since it rotates on the circular arc 6', interference with the steering wheel 4 can be avoided. In this way, if the opening/closing lid 3 is rotated about the fulcrum P after the seat cushion 1a passes the steering wheel 4, the tip of the seat cushion 1a will trace the arc 7, and the engine Enables sufficient opening for room inspection.

FIG. 5 shows an embodiment of the present invention, in which a seat cushion 10a is pivotally supported by a pin 13 on a support member 12 that stands up from the rear end of an upper rail 11 that is a component of the seat longitudinal adjustment mechanism. There is. This pin 13 has the same function as the fulcrum O described above.

A seat back 1 is attached to the upper end of the support member 12.
4 is fixed with a mounting screw 15 or the like. The upper rail 11 is fitted into the lower rail 16, and is movable in the front and rear directions relative to the lower rail 16, and is fixed at a predetermined position. Reference numeral 17 indicates a seat frame;
The tip of a latch 18, one end of which is attached to the seat frame 17, is hooked onto the upper rail 11, thereby preventing unnecessary rotation of the seat cushion 10a. Further, reference numeral 19 indicates a support member that supports the tip of the seat cushion 10a on the upper rail 11.

In this example, when inspecting the engine room, if the latch 18 is released, the seat cushion 1
Even if the seat cushion 10a is in the forward position, the seat cushion 10a can be rotated about the pin 13 serving as a fulcrum without interfering with the steering wheel. After that, as explained in FIG. 4, even if the cover is fully opened, the seat cushion 10a
does not cause interference with the steering wheel, and allows inspection of the engine room with sufficient opening.

In the embodiment described above, the attachment relationship of the seat back 14 to the seat cushion 10a is fixed in a fixed relationship, and as the seat cushion 10a is rotated, the seat back 14 is also tilted backward.

In this case, there is no problem if the vehicle has a structure that has sufficient space at the rear of the seat back 14, but for example, a truck may have a back panel, or a van-type vehicle may have a partition bar, so that the tip of the seat back is located near the back panel. Otherwise, it interferes with the partition bar, and the rotation of the seat cushion and the rotation of the opening/closing lid are significantly restricted.

For example, referring to FIG. 6, the upper end of the seat back 140 is already in a position close to the back panel 150 when the seat is in normal use. Even if the seat back 140 is rotated to the position shown by the imaginary line where it does not interfere with the wheel 400, the seat back 140 will come into contact with the back panel 150, and the opening/closing lid 300 will not be able to open around the fulcrum P.

In this case, a fulcrum Q may be further provided at the base end of the seat bag 140, and the seat bag 140 may be configured to be able to rotate around the fulcrum Q so as to approach the seat cushion 100a, that is, to be able to be folded forward.

If configured in this way, as shown in Figure 7,
Once the seat cushion 100a is
If the opening/closing lid 300 is opened after rotating to a spatial position where it does not interfere with the wheel 400, the tip of the seat back 140 will immediately come into contact with the back panel 150, but after this contact, the opening/closing lid 30
In response to the opening operation of 0, the seat back 140 begins to rotate forward about the fulcrum Q, and eventually it becomes possible to open the opening/closing lid to the position shown by the imaginary line, and the engine room is fully opened. can be inspected. In addition, in the figure, it appears that the tip of the opening/closing lid 300 and the steering wheel 400 are interfering with each other, but the interference part of the opening/closing lid 300 is locally cut out in a concave shape and a notch 159 (eighth
There is no problem if you form the following (see figure).

Next, with reference to FIG. 8, a configuration for rotating the seat bag 140 forward will be described.

In the figure, a first bracket 141 in the shape of an elongated plate is attached to the side of a seat bag 140 with a mounting screw 14.
2,143 etc. is fixed. Next, the lower half of the first bracket 141 is superimposed on the inside of the second bracket 144, which is a plate-like plate having a substantially triangular shape, and forms the fulcrum Q. It is pivotally connected by a pin 145.

The second bracket 144 is fixed to a vertical wall 146a of a mounting plate 146 having an L-shaped side surface using mounting screws 147 and 148. Furthermore, this mounting plate 146 is integrally constructed with an upper rail 110 that is a part of the seat longitudinal adjustment mechanism, and this upper rail 110 is engaged with a lower rail 160. The lower rail 160 is fixed to the opening/closing lid 300.

Next, the seat cushion 100a is supported by a seat frame 149, and the seat frame 149 is constructed substantially integrally with the mounting plate 146.

With the above configuration, the entire seat is placed on the upper rail 110, which moves back and forth while being guided by the lower rail 160, and is positioned by a stopper mechanism (not shown) at an appropriate seat position suitable for driving.

Next, a stopper pin 151 is implanted inside the second bracket 144, and the stopper pin 151 is engaged with a recess 152b of a stopper member 152 having an arcuate surface 152a.

The stopper member 152 is stacked on the inside of the first bracket 141, and is pivotally supported on the second bracket 144 by a pin 153 that constitutes the fulcrum O, which is the center of rotation of the seat cushion 100a. Furthermore, this stopper member 15
A tension spring 155 is provided between the seat frame 149 and the raised cut 154 formed at the rear end of the seat frame 149.
is hung.

Next, on the inside of the stopper member 152, a bracket 156 whose base end is integral with the seat frame 149 is stacked, and an upper fold 156a of the bracket 156 is hung over the upper part of the stopper member 152.

In such a configuration, the following operations are performed when inspecting the engine room.

First, a latch (not shown) is removed and the seat cushion 100a is lifted. Then, the seat cushion 100a rotates around the pin 153 (fulcrum O), and at the same time, the fold 156a pushes down the stopper member 152. That is, the stopper member 152 is rotated clockwise about the pin 153 (fulcrum O) against the tension force of the spring 155, and as a result, the stopper member 152
51 comes to come off the concave portion 152b and ride on the circular arc surface 152a.

In this state, the seat back 140 is attached to the pin 14.
This means that the seat cushion 100a can now be tilted forward around point 5, and corresponds to when the seat cushion 100a is located at the position shown by the imaginary line in FIG.

Therefore, if the opening/closing lid 300 is lifted from this state, the seat back 140 is relatively pushed by the back panel and rotates about the pin 145 (fulcrum point Q) in a tendency to fall forward. Achieve the posture shown by the line.

After completing a predetermined task such as inspecting the engine room, the seat cushion 100a is lowered and the seat back 140 is raised. At that time, pin 151
slides on the arcuate surface 152a. And spring 1
of the stopper member 152 due to the tightening force of 55.
By rotating counterclockwise about the pin 153 (fulcrum O), the pin 151 falls into the recess 152b, and the position of the seat back 140 is locked.

As explained above, according to the present invention, the opening/closing operation of the opening/closing lid can be easily performed, which is convenient for inspecting the engine compartment.
