Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a seat device for a cab-over type vehicle or a one-box vehicle in which the upper part of the engine compartment is covered with a floor panel.

[Prior Art] As is well known, in a cab-over type car or a one-box car in which the upper part of the engine room is covered with a floor panel, a driver's cab is provided above the floor panel, and the floor surface of the driver's cab is formed. The front seat is placed on the floor panel. In such automobiles, in order to secure a storage space for the engine, a protrusion that protrudes upward is formed approximately at the center of the portion of the floor panel that forms the floor surface of the driver's cab. In addition, front wheels are usually placed on the left and right sides of the engine, and in order to avoid complicating the shape of the floor panel by providing tire houses that cover the upper part of the front wheels on the left and right sides of the protrusion, It is known that the protrusion extends over the entire length of the vehicle in the width direction so that it can be used as both left and right tire houses. In such automobiles, for example,
As shown in Japanese Patent No. 53925, front seats such as a driver's seat and a passenger's seat are placed on the protrusion (engine deck).

On the other hand, the rear floor following the engine deck needs to be set as low as possible in order to ensure head clearance for rear seat occupants and ease of getting in and out of the vehicle.For this reason, the engine deck should be lowered at its rear end. and is connected to the rear floor. In other words, the engine deck and rear floor are not flat, but there is a large step between them.

However, when the floor surface of an automobile is formed as described above, the front side and the rear side of the passenger compartment are psychologically separated by the engine deck, which extends over the entire length of the vehicle in the width direction. This is unfavorable in terms of communication between the front and rear sides, and also prevents smooth movement of passengers between the front and rear sides, resulting in a so-called walk-through. There are disadvantages such as poor sex.

By the way, it has been considered to increase the distance between the front and rear wheels for the purpose of improving the driving stability of a car, but in this case,
Since the front wheels can be positioned ahead of the engine, there is no need to extend the engine deck across the entire width of the vehicle, and the engine deck and rear floor can be made flat except for the upper part of the engine. , problems such as communication and walk-through performance between the front side and the rear side can be solved.

[Problem to be solved by the invention] However, when the front seat is placed on the engine deck, especially when the engine deck has a protruding part for storing engine auxiliary equipment, etc. There was a problem that it was difficult to take a sufficiently comfortable posture, such as the inability to fully recline the seat.

Furthermore, conventionally, the front seat and the rear seat have not been associated with each other during use.

This invention was made in view of the above-mentioned problems, and the purpose of this invention is to provide a seat device for a cab-over type car or a one-box car that can put the front seat in a comfortable position and improve the seating comfort. shall be.

[Means for solving the problem] Therefore, in this invention, the upper part of the engine compartment is covered with a floor panel, and on the floor panel, there are seats located in the first row (front seats) and behind the front seats. In a car with a second row seat (rear seat) installed in parallel,
A front seat that can be placed flat is placed on the engine deck, while a rear seat that can be folded is placed on a rear floor that continues behind the engine deck, and one of the front and rear legs that supports the seat cushion of the rear seat is placed on the rear floor that follows the engine deck. The front legs are pivotally supported on the rear floor at both left and right ends, and an adjustment mechanism is provided between the seat cushion and the front legs to adjust the support angle of the front legs, and the front seat of the engine deck is placed on the part where the front seat is placed. and the rear floor are formed flat, and when the front seat is in a flat state, the folded rear seat forms a backrest of the front seat.

[Effects of the invention] According to this invention, since the portion of the engine deck on which the front seat is placed and the rear floor are formed flat, the front seat can be fully reclined. In addition, when the front seat is fully reclined to a flat state, the folded rear seat forms the backrest of the front seat, so the occupant can lean against the backrest while stretching their legs on the front seat. The front seat can be placed in a so-called half-bed state, and the comfort of the front seat can be improved.

Furthermore, the adjustment mechanism is provided between the seat cushion of the rear seat and the front legs so that the support angle of the front legs can be adjusted. The inclination angle can be adjusted. That is, the reclining angle in the half-bed state can be freely adjusted, and the sitting comfort in the half-bed state can be made even more comfortable.
