BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for forming a cot in a truck having a bedless cab, and particularly in a medium or small truck.

[0002]

2. Description of the Related Art Conventionally, when waiting for receipt of goods, bedless 4
Since a medium-sized vehicle such as a ton vehicle is not equipped with a bed, the occupant is usually forced to rest in an inconvenient posture by reclining the seat, and some improvement measures are desired.

To solve the above problem, it has been proposed to provide a bed 55 on the back of a passenger seat similar to a large vehicle as shown in FIG. 7 (A). In this case, the cab space Y is used.
Has the same size as a large-sized vehicle, and there is a problem in the medium-sized vehicle in which the total length of the vehicle is restricted, resulting in a reduction in the length of the luggage loading section. Further, as shown in FIG. 2B, a seat back 54 of an occupant seat 53 provided on the floor 52.
A retractable bed has been proposed in which a bed 55 is provided on the upper part of the seat so that it can be stored in the direction of the arrow. A sufficiently large bed can be provided even for the cab space, but when the vehicle is in operation, the rear window 56 is in a stored state, so that its field of view is blocked, making it difficult to directly confirm the rear field of view and the height inside the cab room. The height must be increased, and a fall prevention device from the bed is also required.

As a solution to this, as shown in FIG. 7 (C), the mounting position 57 of the bed 55 is lowered so that the seat back 54 of the occupant seat 53 can be tilted forward to secure a space for use. Although a thing has been considered and proposed, in this case, the bed needs to be provided with a window portion 55a which functions as a rear window at the time of storage.
There is a problem that requires significant changes on the body side (addition of reinforcement, etc.).

In addition to the above proposal, the bed is divided into a fixed bed cushion fixed horizontally in the cab space behind the rear of the occupant seat, and the cushion is tilted backward toward the rear side of the cab via a hinge-like joint. Proposals for providing a movable bed cushion having a length facing the driver's seat side and forming a simple bed effectively using the passenger seat and the center seat have been proposed, for example, in Japanese Utility Model Laid-Open No. 2-868.
No. 24 publication. In this proposal, after the seat backs of the center seat and the passenger seat side are folded forward, the driver side seat is pivotally moved to the front side by using a special link mechanism, and then the movable bed cushion is moved. Lie down to the front through the joint. As a result, the movable bed cushion, the passenger side seat, and the center seat have three seat cushions in the longitudinal direction on the side of the narrow fixed cushion.
Two divided bed surfaces are formed, and thus a simple bed is formed. However, in such a proposal, a major change work such as changing from the conventional slide system derived from the structure for lying down the movable bed cushion to the retracted position in conjunction with the retracting movement of the driver side seat forward to the link mechanism type In addition to the above-mentioned problem, the movable bed cushion side has three divided bed surfaces formed in the longitudinal direction of the cushion, the passenger side seat, and the seat back of the center seat. bad. It can only be used for cabs with a center seat.

[0006]

The present invention has been made in view of the above problems, and an object thereof is to provide a cot which solves at least the following matters under the above-mentioned limited conditions. That is, a, enabling effective use of a small space in a bedless cab to lie down on a person, b, its recumbent surface being flat and comfortable to sleep on, c, installation without significant changes on the body side D. It is possible to secure a rear view from the rear window.

In a method of forming a simple bed composed of a movable bed cushion,
When using the bed, fold the seat back of the passenger side seat onto the seat surface, slide the driver side seat forward and tilt the seat back forward, and then tilt the movable bed cushion forward. The fixed bed cushion is formed so as to form a simple bed which is substantially flush with the fixed bed cushion by contacting and sticking it to the back side of the passenger seat side seat back and the inclined surface of the forward tilting seat back of the driver side seat. Is characterized by. That is, the bed required for recumbent is divided into two parts by a hinge connection into a fixed bed cushion and a movable bed cushion, and the movable bed cushion does not serve as a passenger seat or a center seat seat back. Compared to the gazette,
Sleep comfort is greatly improved, and a center seat-equipped vehicle that can seat three people or the same portion can be applied to any of the console box types.

In use of the present invention, the seat back of the front passenger side seat is placed on the seat surface in the forward direction and the driver side seat is slid forward as much as possible and tilted forward, and then the movable bed cushion is used. The movable bed cushion is fixed forward on the back of the seat back on the passenger side, on the console box, and on the inclined surface of the forward-sloping seat back on the driver's side to form a simple bed. That is, the space required for the movable bed cushion to be placed on the front side is secured by the front side of the seat back on the passenger seat side, and the seat side is slid forward as much as possible on the driver's side. The space for installing the cot should be secured by tilting it so that the cab space for the fixed bed cushion and the assistant Those which attained effectively utilized by the space that contains the console box formed by the front 倒載 location of the side of the seat back and front slide driver's side seat.

In addition, since the movable bed cushion is folded and folded down from the hinge portion of the fixed bed cushion and leans toward the rear side of the cab during storage, the rear window on the rear side of the cab is not blocked. It is inevitable that the fixed bed cushion is on the bottom side and the movable bed cushion is on the hypotenuse side while allowing the driver's rear view to be secured and the movable bed cushion is leaned toward the rear side of the cab. Moreover, the movable bed cushion can be widened and the fixed bed cushion can be set narrowly, so that a narrow cab space can be effectively used.

The inclined surface may be provided on the inclined surface of the seat back with a fixing means that engages with a side edge portion of the movable bed cushion and fixes the position of the movable bed cushion. Specifically, the fixing means forms an inclined contact surface of a side edge of the movable bed cushion formed in conformity with the inclined surface of the seat back, and an inclined surface of the seat back and / or the movable bed for fixing the position of the movable bed cushion. By configuring with the engaging means provided on the side edge of the cushion, the abutting and positioning of the tilted movable bed cushion on the inclined surface can be performed more reliably.

Further, at the time of storage, the width length in the vehicle front-rear direction when the movable bed cushion is tilted forward is set to be wider than the fixed bed cushion width length, and the movable bed cushion is tilted backward toward the rear side of the cab. When this happens, the cushion side end abuts the cab back wall, and a storage space for storing bedding and the like when the bed is used may be formed between the fixed bed cushion and the cab to effectively utilize the cab space. .

Further, when the movable bed cushion is tilted backward, a small table for accommodating and folding a small table is provided on the back side of the movable bed cushion facing the occupant seat so that the movable bed cushion can be effectively used when stored. Good.
