Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to cab structures for large trucks and the like.

[Conventional technology]

Large trucks used for long-distance transportation are equipped with nap beds behind the driver's seat and passenger seat, but this is not necessarily suitable for short-term rests. Since the parts of the body where drivers feel the most fatigue are the legs that operate the clutch and accelerator, it is preferable to be able to straighten the legs when taking a rest.

However, in the case of a cab-over type truck, even if the driver tilts the backrest backwards using the reclining mechanism, the driver cannot fully stretch his or her legs due to space constraints and the seat structure, as shown in FIG.

[Problem that the invention attempts to solve]

The object of the present invention is to provide a cab structure for a large truck that allows a person to take a resting position with legs stretched out by combining a seat and a bed.

[Means for solving the problem] In order to achieve the above object, the structure of the present invention is such that the backrest of the auxiliary seat is placed on the upper side of the seat so that it is flush with the driver's seat and the bed on the rear side of the auxiliary seat. It can be folded into
The front edge of the bed is axially supported so that it can tilt relative to the floor,
The rear wall is provided with a locking means that engages with a hook provided at the rear edge of the bed to fix the bed in a tilted state, and a resting surface is obtained by the folded state of the backrest and the tilted state of the bed. .

[Effect]

When half or all of the bed 7 is tilted rearward and upward using the front edge as a fulcrum, in combination with the auxiliary seat with the backrest 5 tilted forward, a resting surface is obtained, allowing the occupant to stretch out and rest. It becomes possible to adopt a posture.

[Example of idea]

As shown in Figure 2, the cab of a truck has a driver's seat 3 consisting of a seat 1 and a backrest 2, an auxiliary seat 6 consisting of a seat 4 and a backrest 5, and a seat located behind these seats. It is equipped with a bed 7. The rear part of the bed 7 is defined by a rear wall 12 having a window 10.
Headrests 8 and 9 are attached to the upper end surfaces of each backrest portion 2 and 5.
is installed. The auxiliary seat 6 is configured so that when the backrest portion 5 is tilted forward, it presents a flat surface approximately at the same height as the bed 7.

The floor portion 30 of the cab is raised one step higher from the rear side of the auxiliary seat 6, and the floor portion 30a supporting the bed 7 is raised from the rear wall 12.
It spreads to. Such a configuration is almost the same as the conventional one.

According to the invention, preferably the bed 7 is replaced by the auxiliary seat 6.
The divided body 7 is divided into a rear part and another part.
As shown in FIG. 3, the front edge of the divided body 7a is tiltably supported by a hinge 26 on the floor 30a. A hook 24 is provided at the rear edge of the divided body 7b.

In order to obtain a locking means for fixing the bed 7 in an inclined state, a mounting bracket 21 is fixed to the rear wall 12 with bolts 25, and one end of a band 22 whose length can be adjusted by a buckle 23 is connected to this. band 2
The other end of 2 is engageable with a hook 24.

In the above-mentioned cab structure, when the user takes a nap, when the hook 24 is removed from the band 22, the divided body 7a is placed on the floor 30a, forming the bed 7 which is flush with the divided body 7b.

In the case of rest, as shown in FIGS. 1 and 3, the backrest 5 of the auxiliary seat 6 is folded forward, the divided body 7a of the bed 7 is pulled up around the hinge 26, and the hook 24 is attached to the lower end of the band 22. When the split body 7a is engaged with the split body 7a, the divided body 7a is held at a desired inclined position, and a resting floor surface that is long and inclined in the front and back direction is formed. Therefore,
The occupant can use the divided body 7a as a backrest, place the lower half of his body on the backrest part 5, and stretch his legs straight.

This resting position provides a sense of freedom as you can look out at the scenery outside through the windshield, and is also suitable for smoking or reading, helping to recover from physical and mental fatigue.

[Effect of idea]

As mentioned above, the present invention allows the backrest of the auxiliary seat to be folded upwards so that it is flush with the bed behind the driver's seat and the auxiliary seat, and the front edge of the bed is placed against the floor. Since the rear wall is equipped with a locking means that fixes the bed in a tiltable state, when the bed is tilted rearward and upward using the front edge as a fulcrum, the backrest can be tilted forward and the locking means can be fixed on the rear wall. The combination provides a resting surface and allows the occupant to take a stretched resting position.

The present invention can be implemented at a small cost by simply adding a bed shaft support and a locking member, and by effectively utilizing the cab space, it is possible to rest with a sense of freedom that allows the body to fully stretch.

Claims (1)

[Scope of utility model registration request] The backrest of the auxiliary seat can be folded up to the top of the seat so that it is flush with the bed behind the driver's seat and the auxiliary seat, and the front edge of the bed is pivotably supported so that it can tilt relative to the floor. The cab of a large truck is provided with a locking means on the rear wall that engages with a hook provided at the rear edge to fix the bed in a tilted state, and provides a resting surface depending on the folded state of the backrest and the tilted state of the bed. structure.
