Summary of the Invention

Problems to be Solved by the Invention

[0004] When the bed is arranged behind the driver's seat and the passenger seat as in Patent Document 1, when the seat back is tilted backward, it contacts a part of the bed, and the seat back cannot obtain a sufficient tilt angle. Therefore, before tilting the seat back backward, the user has to secure space by manually retracting a part of the bed that contacts the seat back.

[0005] Therefore, an object of the present disclosure is to provide a vehicle bed that can reduce the labor of the user when moving the seat back and improve the comfort of the user.

Means for Solving the Problems

[0006] The present disclosure is made to solve at least part of the above problems and can be realized as the following aspects or application examples.

[0007] The vehicle bed according to this application example is characterized by comprising: an auxiliary pack portion that moves rearward with the lower side and base end of the seat back in contact due to the rearward tilt of the seat back, and with the tip end opposite to the base end that is in contact lifted; and a bed member that is connected to the tip end of the auxiliary pack portion via a connecting member, and when the auxiliary pack portion moves rearward, the other end opposite to the end to which the connecting member is connected lifts up with the other end as a fulcrum.

[0008] According to this application example, a force is applied diagonally downward and rearward from the contact point between the seat back and the base end of the auxiliary pack, causing the front end of the auxiliary pack to lift and move rearward, and the moved auxiliary pack comes into contact with the bed member. The bed member is then held in an inclined state, and one end of the bed member lifts up with the other end of the bed member as a pivot point, while the auxiliary pack is suspended. In other words, the vehicle bed moves rearward in accordance with the rearward tilt of the seat back. Therefore, the seat back can be tilted fully to the rear. Furthermore, the user does not need to move the auxiliary pack out of the way or perform other tasks to secure space each time they tilt the seat back to the rear. This reduces the effort required of the user when moving the seat back and improves user comfort. [Brief explanation of the drawing]

[Figure 2] Figure 1, section AA shows a cross-sectional view of the vehicle bed according to this embodiment. [Figure 3] This is an enlarged view of the main part I of the vehicle bed shown in Figure 2. [Figure 4] Figure 2 is a cross-sectional view AA showing the vehicle bed when the seat back is tilted. [Modes for carrying out the invention]

[0010] Embodiments of the present invention will be described below with reference to the drawings. However, the present invention is not limited to what is described below, and can be modified and implemented as such without altering its essence. Furthermore, in these embodiments, when referring to the up / down, left / right, and front / back directions, the description will be based on a user seated in the driver's seat.

[0011] Figure 1 is a plan view showing the interior of the cab of a vehicle equipped with a vehicle bed (hereinafter also referred to as "bed") according to this embodiment. Figure 2 is a cross-sectional view of AA in Figure 1. Figure 3 is an enlarged view of the main part I in Figure 2. The vehicle equipped with the bed in this embodiment is, for example, a cargo vehicle such as a truck. The vehicle in this embodiment will be described based on a right-hand drive vehicle.

[0012] As shown in Figure 1, the vehicle's cab 1 includes a driver's seat 2 on the right side of the vehicle, a passenger seat 3 on the left side of the vehicle, a steering wheel 4 in front of the driver's seat 2, an instrument panel 5 in front of the steering wheel 4, and a bed 6 behind the driver's seat 2 and passenger seat 3.

[0013] The driver's seat 2 and the passenger seat 3 are seats for the user to sit in. The driver's seat 2 and the passenger seat 3 have a seat cushion 2a (3a) and a seat back 2b (3b). Both the seat cushion 2a and the seat back 2b are formed of cushioning material with a frame (not shown) built inside.

[0014] The seat cushion 2a is thick and roughly rectangular in shape, and functions as a cushion to support the user's buttocks. The seat back 2b is thick and roughly rectangular in shape, and functions as a backrest to support the user's upper body. The seat back 2b is rotatably attached to the seat cushion 2a at its lower end and can be tilted forward or backward by the user.

[0015] The steering wheel 4 controls the direction of travel of the vehicle via the steering mechanism, based on the driver's steering input. The instrument panel 5 displays information necessary for driving the vehicle, such as the speedometer and fuel level warning light.

[0016] The bed 6 is provided between the driver's seat 2 and the passenger seat 3 and the rear panel 1a of the cab 1. As shown in FIG. 2, the bed 6 is placed on a support blanket 10 fixed to the floor panel 1b forming the floor surface of the cab 1 with fastening materials. There is a space B between the placed bed 6 and the floor panel 1b.

[0017] The support blanket 10 has a flat surface at the upper end and is arranged at a plurality of locations as shown by the broken line in FIG. 1. The plurality of arranged support blankets 10 are configured such that the placed bed 6 is in a flat state (substantially horizontal plane state). In the present embodiment, it is arranged at six locations, specifically at the boundary between the bed unit 60 and the central member 61 described later, the front edge of the central member 61, the central part of the rear edge, and the cab inner wall part side of the bed unit 60.

[0018] As shown in FIG. 1, the bed 6 includes two bed units 60 and a central member 61. The bed units 60 are arranged behind the driver's seat 2 and behind the passenger seat 3. The central member 61 is formed in a rectangular plate shape and is arranged between the left and right bed units 60. Since the configurations of the left and right bed units 60 are the same, the following description will be about the right bed unit 60 (on the driver's seat 2 side), and the description about the left side (on the passenger seat 3 side) will be omitted.

[0019] The bed unit 60 includes a plate-shaped auxiliary pack part 60a and a plate-shaped bed member 60b arranged on the side opposite to the seat back 2b with respect to the auxiliary pack part 60a.

[0020] The auxiliary pack part 60a is formed in a substantially rectangular shape in the vehicle width direction and is arranged behind the seat back 2b in a state separated from the seat back 2b.

[0021] The bed member 60b is formed in a substantially right trapezoidal shape such that the side toward the cab inner wall portion gradually narrows inward as it goes toward the rear panel 1a side in plan view. The bed member 60b is disposed in a state of being separated from the auxiliary pack portion 60a and the rear panel 1a.

[0022] As shown in FIG. 3, the auxiliary pack portion 60a and the bed member 60b are connected via a belt-like connecting member 7. Specifically, one side of the connecting member 7 is fixed to the upper surface edge portion on the rear side of the auxiliary pack portion 60a, and the other side of the connecting member 7 is fixed to the upper surface edge portion on the front side of the bed member 60b. The connecting member 7 has flexibility and is held in a state of being bent in a substantially U shape between the fixed one side and the other side. In the present embodiment, the portion bent in a U shape is housed between the auxiliary pack portion 60a and the bed member 60b.

[0023] Next, the operation of the bed 6 will be described.

[0024] FIG. 4 shows the relationship between the bed 6 and the bed unit 60 when the seat back 2b is tilted maximally to the rear side. The seat back 2b rotates circumferentially about a hinge portion (the center point P in FIG. 4 in the present embodiment) attached to the seat cushion 2a. As shown in FIG. 4, when the seat back 2b is rotated clockwise in a left side view, that is, tilted to the rear side, the lower side of the back surface of the seat back 2b and the upper surface edge portion on the front side (base end side) of the auxiliary pack portion 60a come into contact. In the present embodiment, the portion where the seat back 2b and the auxiliary pack portion 60a come into contact is defined as the contact point Q.

[0025] When the seat back 2b is tilted to the rear side about the center point P, a force is applied to the auxiliary pack portion 60a obliquely downward to the rear at the contact point Q. In FIG. 4, the direction of the applied force is indicated by an arrow X. The auxiliary pack portion 60a to which a force is applied due to the tilt of the seat back 2b moves rearward on the surface of the support blanket 10 while lifting the rear side (tip side) of the auxiliary pack portion 60a.

[0026] As the auxiliary pack section 60a moves towards the rear while lifting its rear end (front end), the front end of the auxiliary pack section 60a comes into contact with one end of the bed member 60b, and moves towards the rear together with the bed member 60b. The other end of the bed member 60b then comes into contact with the rear panel 1a, but because a force is continuously applied from the seat back 2b, an upward force acts (the force escapes) from the point of contact between the auxiliary pack section 60a and the bed member 60b.

[0027] Then, the bed unit 60 is bent upward at the point where the auxiliary pack portion 60a and the bed member 60b come into contact, and the other end of the bed member 60b enters space B. At this time, the lower surface of the bed member 60b comes into contact with the upper edge of the rear end of the support blanket 10, and one end (front side) of the bed member 60b is lifted up using the contact point (fulcrum R in Figure 4 in this embodiment) as a pivot point.

[0028] This makes it possible to automatically move the bed unit 60 to the rear in accordance with the tilt angle (rotation angle) of the seat back 2b.

[0029] Furthermore, when the seat back 2b is returned from a rearward tilted position to a nearly vertical position, the auxiliary pack section 60a tilts downwards at its rear end due to its own weight and falls from an inclined position to a horizontal position. The bed member 60b is then pulled towards the auxiliary pack section 60a via the connecting member 7, causing it to roll over towards the auxiliary pack section 60a. As a result, the auxiliary pack section 60a and the bed member 60b are automatically positioned side by side in a flat position.

[0030] In this embodiment, the bed 6 is subjected to a force applied diagonally downward and rearward from the contact point Q between the seat back 2b and the base end of the auxiliary pack portion 60a. This lifts the front end of the auxiliary pack portion 60a, causing it to move backward, and the moved auxiliary pack portion 60a comes into contact with the bed member 60b. The bed member 60b is then held in an inclined position, with one end lifting up using the other end of the bed member 60b as a pivot point R. In other words, the auxiliary pack portion 60a and the bed member 60b move backward in accordance with the rearward inclination of the seat back 2b. Therefore, the seat back 2b can be tilted fully backward. Furthermore, the user does not need to move the auxiliary pack portion 60a out of the way or perform other tasks to secure space each time they tilt the seat back backward. This reduces the effort required of the user when moving the seat back and improves user comfort.

[0031] This concludes the description of embodiments of the present invention. However, the specific configurations shown in these embodiments are merely examples, and the embodiments of the present invention are not limited to those shown in these embodiments.

[0032] In this embodiment, one end of the connecting member 7 is fixed to the rear upper edge of the auxiliary pack portion 60a, and the other end is fixed to the front upper edge of the bed member 60b. However, for example, the other end of the connecting member may be fixed to the front lower edge of the bed member.

[0033] Furthermore, the bed 6 may act such that, depending on the width of the space between the support blanket 10 and the rear panel 1a, the bed member 60b suspends the auxiliary pack section 60a by the connecting member 7 during the process in which the seat back 2b is tilted to its maximum rearward position. Also, for example, the auxiliary pack section 60a may move even after it has suspended the bed member 60b.

[0034] Furthermore, a string-like connecting member may be provided on the front (base) upper surface of the auxiliary pack section 60a, which connects to the lower back of the seat back 2b. The connecting member holds the auxiliary pack section 60a in a flat position and the seat back 2b in a nearly vertical position, taut and without slack. As a result, when raising the seat back 2b, the auxiliary pack section 60a is pulled forward by the seat back 2b, and the auxiliary pack section 60a and the bed member 60b are automatically positioned side by side in a flat position, reducing the effort required from the user.
