Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a folding vehicle seat suitable for use in vehicles such as double cab trucks in which the rear wall of the passenger compartment is close to the rear side of the seat.

[Conventional technology]

For example, in a double-cab type truck, a wall on the back side of the passenger compartment is located close to the back side of the rear seat, and has generally been fixedly provided in the past. Therefore, when the rear seat side is used as a space for storing luggage when the rear seat is vacant, the space on the seat cushion is simply used as a space for storing luggage. .

[The problem that the idea aims to solve]

However, in the conventional configuration as described above,
The space above the seat cushion on the rear seat side is limited, making it difficult to place large items on top of the seat cushion, and the seats constituting the rear seat often get in the way.

For this reason, it has conventionally been considered to configure the seat back so that it can be folded down in front of the seat, or to configure the seat cushion so that it can be flipped up and rotated in front of the seat to expand the space as a cargo platform as much as possible. However, there are limits, and it is desired that some kind of countermeasure be taken to eliminate these problems.

In particular, for vehicles such as double-cab type trucks that use this type of folding seat, the rear seat is not a very important seat and may be used merely as an auxiliary seat. Taking this into consideration, measures are needed to expand luggage storage space.

[Means to solve the problem]

In order to meet such demands, the foldable vehicle seat according to the present invention has a rear end connected to the free end side of a support arm that is rotatably supported on the floor of the vehicle interior, and a rear end of the support arm that is rotatably supported on the floor of the vehicle interior. The seat cushion is provided so that it can be flipped up and rotated, and the lower end is rotatably supported on the eccentric position of the support arm, which is erected on the rear end side, and the upper end is linked to the rear side wall of the passenger compartment. When the seat cushion flips up and rotates, the seat bag is brought close to the rear side wall of the vehicle interior so as to be approximately parallel to the seat cushion, and the seat cushion is overlapped with respect to the seat bag. It is constructed so that it can be folded together.

[Effect]

According to this invention, the seat cushion is always worn.
The support arm allows the seat to be tilted forward and rotated, allowing it to function as a normal seat.
When using this seat installation space as a storage space for luggage, the seat cushion can be flipped up and rotated to the rear of the seat using the support arm, so that it can be placed over the seat back and along the wall on the back side of the seat. It can be stored and folded into the minimum required space.

〔Example〕

Hereinafter, the present invention will be explained in detail using embodiments shown in the drawings.

Figures 1 to 3 show an embodiment of the folding vehicle seat according to the present invention. In these figures, reference numeral 1 indicates the front part of a double cab type truck, such as a driver's seat (not shown). This is an installation space for a rear seat formed on the back side of the seat, and is formed by a vehicle interior floor surface 2 and a wall portion 3 on the back side of the seat. In this installation space 1, a foldable vehicle seat (hereinafter simply referred to as a foldable seat) 10, which characterizes the present invention, is disposed on the floor surface 2 of the vehicle interior.

Now, according to the present invention, the folding seat 1 arranged in the installation space 1 of such a rear seat
0, the rear end of which is connected and fixed to the free end side of a support arm 11 which is rotatably supported on the cabin floor 2 with bolts 12a etc., and is provided so that it can be flipped up and rotated behind the seat 10. The seat cushion 12 is erected on the rear end side, and its lower end is rotatably supported by a pivot pin 13a at an eccentric position of the support arm 12, and its upper end is linked 14 to the rear side wall 3 of the passenger compartment. When the seat cushion 12 flips up and rotates, the seat back 13 is moved approximately parallel to and approached the rear side wall 3 of the vehicle interior, and the seat back The feature is that the seat cushion 12 is folded over the seat cushion 13. In addition, 15 in the figure is a bracket for pivotally supporting the rotating shaft portion 11a of the support arm 11 on the stepped portion on the side of the floor surface 2 of the vehicle compartment, and as is clear from FIG. Then, on the lower side of the front end of the seat cushion 12, there is a pivot pin 16.
A foldable leg portion 16 is attached by a, and the leg portions 16 can be folded together and stacked on top of each other when the sheet 10 described above is folded. Here, FIG. 3 shows only the frame structure of the seat cushion 12 and seat bag 13.

According to this configuration, the seat cushion 12 is normally rotated forward by the support arm 11 and supported by the legs 16, so that it can be used as a normal seat 10, as is clear from FIG. In addition, when using the seat installation space 1 as a luggage storage, the seat cushion 12 can be raised and rotated to the rear of the seat 10 by the support arm 11 to support the seat back 13. The seat can be stored by being moved closer to the wall 3 by the arm 11 and stacked one on top of the other, and then folded so as to be substantially parallel to the back side wall 3 of the seat as shown in FIG. It is.

Therefore, in such a configuration, although the configuration is simple and inexpensive, the normal sheet 1 is always used.
By flipping up and rotating the seat cushion 12 to the rear of the seat by the support arm 11, the seat cushion 12 can be raised and rotated to the rear of the seat, so that the seat back wall 3
It has the advantage that it can be folded and stored in the minimum necessary space along the lines, and that this seat installation space 1 can be expanded and utilized to the maximum as a luggage storage space.

Note that the present invention is not limited to the structure of the embodiment described above, and the shape, structure, etc. of each part of the foldable seat 10 can be changed.
It is free to modify and change as necessary, and the sheet to which it can be applied is not limited to the double cab type track mentioned above.
This can be effectively applied to various vehicles that require this type of luggage storage space.

[Effect of idea]

As explained above, according to the foldable vehicle seat according to the present invention, the rear end portion is connected to the free end side of the support arm rotatably supported on the floor surface of the vehicle interior, and the rear end portion is flipped up to the rear of the seat. The seat cushion is rotatably provided, and the lower end is rotatably supported on the eccentric position of the support arm, and the upper end is connected to the rear side wall of the passenger compartment via a link. and a seat back supported by the seat cushion, and when the seat cushion flips up and rotates, the seat back approaches the rear side wall of the vehicle interior so as to be approximately parallel to the seat back, and the seat cushion is overlapped with the seat back. Because it is constructed to be foldable, despite its simple and inexpensive construction, the seat cushion can normally be rotated forward by the support arm to function as a normal seat. By flipping up and rotating the seat to the rear of the seat using the support arm, it can be stored along the wall on the back side of the seat while stacked on top of the seat bag, and folded into the minimum necessary space. This has various practical effects, such as being able to expand the seat installation space as a luggage storage space and make maximum use of it.
