Description

Detailed Description of the Invention (Industrial Application Field) This invention is a cab-over type vehicle in which a passenger seat is mounted above a service hole in an engine deck that is raised in the center of the floor between the driver's seat and the driver's seat. vehicle seat equipment,
In particular, it relates to a seat device on the passenger side.

(Prior Art) In many cab-over type vehicles, a passenger seat is installed above a service hole in an engine deck that is raised in the center of the floor.

In order to open the service hole and inspect the engine, the passenger seat is constructed so that it can be flipped forward (for example,
No. 02532 ¥Q).

(Problem to be solved by the invention) In recent cab-over type vehicles, the driver's cabin and luggage compartment are integrated, the passenger seat in the driver's seat tank is eliminated, and the driver can walk directly into the luggage compartment without exiting the vehicle. There are vehicles that are structured to go there. This vehicle is called a walk-through vehicle and is used as a collection and delivery vehicle for parcel deliveries.

Since the walk-through vehicle described above does not have a passenger seat, it is not possible for a driver's assistant to ride along with the vehicle, which greatly limits its usage. In a typical cab-over type vehicle with a passenger seat, the driver cannot move into the luggage compartment without getting out of the vehicle unless the driver makes an unnatural movement such as climbing over the seat.

This invention was made in view of the above-mentioned conventional problems, and its purpose is to maintain good engine serviceability in cab-over type vehicles where the passenger seat is located above the service hole of the engine deck next to the driver's seat. To provide a seat device for a vehicle that allows a driver to pass through the side of a passenger seat and walk to the rear of a vehicle interior, and that provides good comfort through various moving operations.

(Means for Solving the Problems) Therefore, in the present invention, in a vehicle in which a passenger seat is mounted above an engine service hole that is raised in the center of the floor between the driver's seat and the driver's seat, the seat is and a lateral flip-up mechanism that rotates the seat upward using the driver's seat side end of the seat cushion as a fulcrum.

Further, the seat device provided with the above-mentioned lateral movement mechanism and lateral flip-up mechanism is provided with a slide mechanism for moving the seat in the front-rear direction.

(Function) When the passenger seat is moved to the driver's seat side by the lateral movement mechanism, a space is created on the side opposite to the driver's seat by the amount that the passenger seat has moved, and the driver can slip through the space and enter the vehicle. You can walk to the rear of the car. Further, when the seat is rotated upward by the side flip-up mechanism, a service hole for the engine deck appears below, and the engine can be inspected from the side where the passenger seat was located.

Further, the seat can be slid forward and backward as desired according to the passenger's preference.

(Embodiment) FIGS. 1 and 2 show a schematic configuration of a cab-over type vehicle according to a first embodiment of the present invention.

1a and 1b are the seat cushion and seat back of the driver's seat. 2a and 2b are the seat cushion and seat back of the passenger seat. Driver's seat 1a on floor 3 of the vehicle body

The passenger seat cushion 2a is mounted above the service hole cover 5. With the configuration described in detail below, the passenger seats 2a and 2b are movable in the vehicle width direction from the illustrated state toward the driver's seat. Further, the seat back 2b can be folded onto the seat cushion 2a (this is a normal configuration and will therefore be omitted). In this state, use the end of the seat cushion 2a on the driver's seat side as a fulcrum to hold the passenger seats 2a and 2b.
It is configured as a sideways flip-up type that rotates upward.

3 to 6 show detailed configurations of the lateral movement mechanism and lateral flip-up mechanism for the passenger seat.

Near the top of the engine deck 4 is a roller 9 shown in FIG.
is fixed to the floor panel via a bracket 10. There are two rollers 9, and their respective rotation centers are on the same straight line, and the rotation center lines are parallel to the longitudinal direction of the vehicle body. The seat frame 6 includes a front frame 6a, a rear frame 6b, a frame 6c near the driver's seat, and a left frame 6d on the door side.

Note that the structure of the attachment of the seat frame 6 and the floor panel side is symmetrical from front to back, and although the configuration of the rear side is hidden in FIG. 3, etc., it is the same as the configuration of the front side.

The front frame 6a and rear frame 6b of the seat frame 6 are attached so as to embrace a roller 9 on the floor 3 side (engine deck 4 side), and the seat frame 6 is moved in the vehicle width direction using this roller 9 as a guide. A sideways flip-up movement is performed.

Two cylindrical hooks 11 and 12 are attached to the front side of the front frame 6a near the driver's seat. Cylindrical hooks 11 and 12 are also attached to the rear frame 6b symmetrically in the front and rear. In addition, two hooks 13 and 14 are provided on the lower surface of the front frame 6a on the door side.

As shown in FIG. 3, the state in which the hook 11 is locked by the toggle clamp 5 and the hook 13 is locked by the toggle clamp 16 is the normal usage state of the passenger seats 2a and 2b. In this state of use, the stand 17 provided at the left end of the floor 3 is erected, and the stand 17 supports the left break 6d of the seat frame 6 from below. The stand 17 can be laid down horizontally using a bracket 18 as a hinge, and four parts 19 are formed on the floor 3 surface of this portion, as shown in FIG. 5, to accommodate the stand 17 laid down horizontally.

In addition, in FIG. 4, 20 is a stop rubber attached to the upper surface of the engine deck 4, and the seat frame 6 comes into contact with this.

When the passenger seat is in use as described above, the center point of the cylindrical hook 1 coincides with the center point of the roller 9, as shown in FIG. If you want to inspect the engine from this state, flip up the passenger seat laterally as follows. First, the seat back 2b is folded onto the seat cushion 2a. Next, open the two toggle clamps 16 and attach the hook 13.
Remove from.

In this state, when the left end (door side) of the seat cushion 2a is lifted upward, the roller 9 and the cylindrical hook 11 become rotational fulcrums, and the seat frame 6 (the entire passenger seat) rotates and flips up to the driver's seat. Then, the service hole cover 5 that was hidden on the passenger seat appears, open the cover 5 and remove the engine deck 4.
The engine inside can be inspected. Incidentally, at this time, the stand 17 is set down.

Further, in order to move the passenger seat from the above-mentioned usage state to the driver's seat side and enter the walk-through state, the following operation is performed. First, remove the two toggle clamps 15 from the hooks 11, and then remove the two toggle clamps 16 from the hooks 13.
Remove from. Then, the seat frame 6 is only engaged with the two rollers 9 and released from the floor panel side.

Therefore, as shown by arrow Y in FIG.
When pushed toward the driver's seat, the seat frame 6 (the entire passenger seat) moves toward the driver's seat using the rollers 9 as a guide. When the seat frame 6 is moved laterally by a predetermined amount, the hook 12 comes to the position of the toggle clamp 15 and the hook 14 comes to the position of the toggle clamp 16. Therefore, the hook 12 is locked with the toggle clamp 15, and the hook 14 is locked with the toggle clamp 16. Also, the stand 17 is laid down on the floor panel. In this way, passenger seats 2a and 2b
The entire body is fixed in a position moved closer to the driver's seat than in normal use, resulting in a large space being opened between the passenger door and the passenger seat. The driver can walk through this space to the luggage compartment at the rear of the vehicle.

Further, in this first embodiment, the seat frame 6 has two
Book support frames 7 and 8 are fixed in parallel in the front-rear direction, and slide rails 7a and 8a for moving the seat cushion 2a in the front-rear direction are mounted on the support frames 7 and 8.
is attached so that the passenger seats 2a and 2b are movable in the front and rear directions.

Note that the configuration in which the seat is movable in the front and rear directions by the slide rails 7a and 8a is well known, so a description thereof will be omitted.

Next, a second embodiment of the present invention will be described with reference to FIGS. 7 to 10.

(Effects of the Invention) As explained in detail above, in the vehicle seat device according to the present invention, the passenger seat seat attached to the upper part of the service hole of the engine deck is moved in the width direction of the vehicle and brought closer to the driver's seat side. Since the vehicle is constructed so that a person can easily pass between the passenger seat and the door on the passenger side, a space is created through which a person can easily pass between the driver's seat and the rear of the vehicle body. In other words, a cab-over type vehicle with a passenger seat can be used for purposes similar to a walk-through panel pan. Furthermore, since the passenger seat is configured to flip up toward the driver's seat, engine servicing work can be easily performed from the large space on the passenger's seat side.

Furthermore, while maintaining good walk-through performance and engine serviceability, it also has the function of moving the seat back and forth, and provides good comfort for the occupants.
