Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a support structure for a retractable double-row seat in a passenger/freight vehicle.

[Conventional technology]

As shown in FIG. 1, in a conventional vehicle for both cargo and passenger use, a front floor section 31 on which a driver's seat 1 is installed is higher than a rear floor section 32 due to the relationship with the engine arranged under the floor. The front seat 2 and the rear seat 12 are attached to the rear floor part 32. Rear seat 12 has backrest 1
4 to the upper side of the seat part 13, the front legs 15 are folded forward about the pins 17 that support the rear floor part 32, and the rear legs 16 are folded to the lower side of the seat part 13 to be stored. However, this only increases the cargo loading space in the rear floor section 32 by the floor of the rear seat 12, and the floor of the front seat 2 cannot be utilized.

In the retractable double-row seat disclosed in Utility Model Application Publication No. 57-168438, the front legs of the rear seat are moved forward along a longitudinal guide rail installed on the floor between the front seat and the rear seat. Since the seats and backrests of the front and rear seats are stored in close contact with each other on the same plane and upright, the floors of the front and rear seats can be used as cargo loading space.

However, this requires fixing the guide rail that moves the rear seat forward to the floor, attaching the guide roller that engages the guide rail to the lower end of the front leg of the rear seat, and preventing the rear seat from moving forward when in use. The structure is complicated, including the provision of an anti-slip mechanism, and the rather long guide rail protrudes above the floor, causing problems in loading and moving luggage.

In the seat disclosed in Utility Model Publication No. 54-92524,
The front legs of the rear seat are connected to links extending rearward from the rear legs of the front seat, while the backrest and the rear legs are integrally supported in a tiltable manner by a shaft at the rear end of the seat. When the front legs of the rear seat are folded forward and the backrest and rear legs are also folded down on their axis, the seat and backrest are stored on the same plane and stand upright on the floor. In this seat, the front seat and the rear seat are connected by a link, so when the vehicle body is subjected to vibrations, the vibrations are transmitted between the seats, resulting in poor ride comfort and an excessive load acting on the link. In addition, when the front and rear seats are stored in an upright position with their seat portions and backrests extended, the effective use of space is limited when bulky items are loaded above.

[Problem that the invention attempts to solve]

An object of the present invention is to provide a support structure for a double-row seat that is simple in construction, has few component members protruding from the floor in the stored state, and allows the storage state to be selected depending on the shape of the luggage. It is in.

[Means for solving problems]

In order to achieve the above object, the configuration of the present invention is such that the front legs of the front seat are pivotably supported on the floor so that they can be tilted forward.
The front legs of the rear seat are connected to the tip of a link whose base end is pivotably supported on the floor between the front and rear seats so that it can be tilted back and forth, and the rear legs are connected to the rear ends of the seats of the front and rear seats. The backrest is pivoted so that it can be folded downwards, and the backrest can be tilted to the top and rear of the seat. The front and rear seats can be stored close to each other in a state where the seat is folded upward and stands upright on the floor.

[Effect]

The seat can be stored in a stored state in which the backrest is folded backwards relative to the seat and stands upright on the floor, and in a state in which the backrest is folded over the seat and stands upright on the floor. Therefore, depending on the load to be loaded, for example, the latter storage state can be selected for a bulky item such as a table, and the former storage state can be selected for a heavy item such as a box.

[Example of idea]

As shown in FIG. 2, the front seat 2 can be tilted rearward about an axis 8 by a known reclining mechanism, with the lower end of the backrest 4 attached to the rear end of the seat 3. foldably coupled to. Front legs 5 fixed to the seat 3 are supported on the rear floor 32 by a shaft 7 so as to be tiltable forward. The rear legs 6 are supported by a shaft 8 against the rear end of the seat 3, and cannot be rotated counterclockwise from the illustrated state, but can be rotated clockwise and folded toward the bottom of the seat 3. .

The same applies to the rear seat 12, and a backrest 14 is provided at the rear end of the seat 13, which can be tilted rearward about an axis 18 by a reclining mechanism.
It is foldably connected to the upper side of 3. Seat part 13
A front leg 15 is fixed to the seat, and a rear leg 16 is foldably connected to the lower side of the seat 13 by a shaft 18.

According to the present invention, the lower end of the front leg 15 of the rear seat 12 is connected to the tip of the link 22 by the pin 17. The base end portion of the link 22 is supported by the rear floor portion 32 by the shaft 21 so as to be tiltable back and forth. Link 2
2 is determined in relation to the arrangement of the front seat 2. Although it is preferable that the links 22 be provided on the left and right front legs 15, they may be connected to a horizontal member that connects the left and right front legs 15. In this case link 22
It is sufficient to arrange only one at the center of the rear floor portion 32 in the vehicle width direction.

To store the rear seat 12 from the usage state shown in FIG. 2, as shown by the chain line in FIG.
The backrest 14 of the backrest 14 is tilted to the rear so that it is almost flush with the seat 13. Next, the seat portion 13 and the backrest 14 are pulled up around the axis 17 of the front legs 15. By folding the rear legs 16 to the underside of the seat 13, the cargo loading space on the rear floor 32 is expanded.

To store the front seat 2 as well, as shown in Figure 4, fold the backrest 4 to the rear and fold the seat 3 and front legs 5 forward about the axis 7.
is stored in an upright position. Next, as shown by the broken line in FIG. 4, when the rear seat 12 is lifted and the link 22 is rotated 180 degrees around the shaft 21 and tilted forward, the rear seat 12 changes from the state shown in FIG. Move forward in parallel by twice the length. In this manner, the front seat 2 and the rear seat 12 are stored close to each other behind the driver's seat 1, so that the rear floor portion 32 of the front seat 2 and the rear seat 12 becomes a cargo loading space.

In addition, in the stowed state shown in Fig. 4, there is a slight gap between the stowed front seat 2 and the rear seat 12, but this gap can be used to prop up and transport plate-shaped items such as picture frames and plate glass. If you do this, there is less risk of damage.

As shown in FIG. 5, when the backrests 4 and 14 of the front seat 2 and the rear seat 12 are folded above the seat parts 3 and 13 and stored in an upright position with respect to the rear floor part 32, the stored front seats are 2 and the space above the rear seat 12 is expanded, making it suitable for loading bulky items such as tables.

[Effect of idea]

As mentioned above, the present invention is based on the tip of a link that has the front legs of the front seat axially supported on the floor so that they can be tilted forward and the base end axially supported on the floor between the front and rear seats so that they can be tilted back and forth. The front legs of the rear seats are connected, and each front and rear seat has a shaft support at the rear end of the seat so that the rear legs can be folded to the bottom of the seat, and the backrest can be tilted to the top and rear of the seat. However, the front and rear seats can be stored close together in a state where the seat and backrest extend straight and stand upright on the floor, and a state where the backrest is folded over the seat and stand upright on the floor. Therefore, depending on the shape of the cargo to be loaded, a stored state in which the seat and backrest extend in series and stand upright on the floor, and a stored state in which the backrest is folded over the seat and stand upright on the floor can be obtained. . In the former case, it is convenient for loading plate-shaped luggage by leaning it against the space between the stowed front seats and the rear seats.
In the latter case, the area of the ground contact area is small and it is convenient for loading items that extend upward (such as tables).

According to the present invention, the configuration is very simple and the number of parts is small, which helps reduce costs.

Compared to conventional models, the number of guide rails and other items that protrude above the floor when stored is halved, making it easier to move loaded cargo.

Since the link does not completely block the space between the front seat and the rear seat, the passenger's passage to the seat is not obstructed.
