Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a seat in which a front seat and a rear seat are foldably connected.

[Prior art]

Conventionally, in the case of one-box type automobiles, the front and rear seats are placed on the floor behind the bulkhead, which covers the opening of the engine compartment and has the so-called front seats, such as the driver's seat and the auxiliary seat, mounted on the top surface of the bulkhead. There is a vehicle in which the seats are arranged vertically so that they can be folded, and by folding them toward the bulkhead side, the vehicle floor can be used as a luggage compartment. This seat will be explained with reference to FIGS. 3 and 4. The seat 1 consists of a front seat 4 and a rear seat 5 which are foldably connected vertically to a vehicle floor 3 behind a bulkhead 2. This front seat 4 includes a front leg 6 fixed to the vehicle floor 3, a seat cushion part 8 whose front lower part is attached to the upper part of the front leg 6 via a hinge part 7 so as to be rotatable forward, and this seat cushion part. At the rear of the seat cushion section 8, there is a seat back section 10 which is arranged to stand upright in a rearwardly inclined manner and which is attached to the lower part of the seat cushion section 8 so as to be rotatable forwardly via a hinge section 9; It consists of a rear leg 12 which is arranged in a backward-slanting manner via a hinge part 11 and is foldable toward the back side of the seat cushion part 8 with the hinge part 11 at the center. Further, the rear seat 5 has a front leg 13 which is attached to the hinge part 7 at the upper part of the front leg 6 of the front seat 4 so as to be able to rotate upwardly, and which is U-shaped in side view and extends over the vehicle floor 3. Seat cushion part 15 is attached to the upper end of the rear vertical part 13a of 13 via a hinge part 14 so as to be freely rotatable forward.
, a seat back part 17 which is arranged to stand upright at the rear of the seat cushion part 15 and is assembled so as to be tilted forward so as to be rotatable forward via a lower hinge part 16; A rear leg 19 is disposed at the rear lower part of the section 15 in a backward-slanting manner via a hinge section 18 and is foldable toward the back side of the seat cushion section 15 around the hinge section 18.
It consists of

Therefore, the seat 1 having the above structure moves forward with the seat back part 10 of the front seat 4 centered on the lower hinge part 9, and moves the seat back part 10 together with the seat back part 10 in a state where its seating surface overlaps the seating surface of the seat cushion part 8. Then, the seat back part 8 is moved upward around the upper hinge part 7, the rear legs 12 are folded around the hinge part 11 and overlapped with the back surface of the seat cushion part 8, and then the seat back part 17 of the rear seat 5 is folded. It is moved forward around the lower hinge part 16, its seating surface is overlapped with the seating surface of the seat cushion part 15, and it is latched onto the seat cushion part 15 by a locking means (not shown), and the seat cushion part 15 is fixed to the upper part. The rear legs 19 are folded around the hinge part 18 and overlapped with the back surface of the seat cushion part 15, and finally the front legs 13 are folded up around the hinge part 14.
By moving the front seat 4 upward around the upper hinge part 7 of the front leg 6, it can be folded as shown in FIG. It is made possible to do so.

[Problem that the invention attempts to solve]

However, in the above-mentioned structure, when the seat 1 is folded, the front seat 4 is vertically arranged above the vehicle floor 3, and the rear seat 5 is arranged horizontally above the front seat 4, so there is no cargo space. When trying to spread out the front seat 4
If the fixed position of the front legs 6 of the front legs 6 is arranged close to the bulkhead 2 side, the rear seat 5 will collide with the seat back portion 21 of the float seat 20 on the bulkhead 2 when the seat 1 is folded. Therefore, a large gap is left as a dead space between the front seat 4 and the bulkhead 2 in the folded state.

Therefore, the present invention provides an easy-to-fold seat that can reduce the front-to-back width of the dead space and expand the cargo space.

[Means for solving problems]

The present invention provides a hinge that is formed by pivotally connecting the upper end of the front leg and the lower end of a connecting arm that protrudes toward the vehicle floor from the bottom of the front part of the seat cushion part, which is located closer to the rear than the front part of the seat cushion part. The seat cushion part is rotatable forward through a seat cushion part, the seat back part is rotatable forward, a vertical part that is integrated with the seat back part and extends toward the vehicle floor, and a vertical part extending rearward along the floor. a front seat having rear legs formed of an extending horizontal portion; a seat cushion portion having legs whose lower ends are rotatably supported forwardly on the rear end of the horizontal portion; and a seat back portion rotatable forwardly. , and a rear seat having rear legs that are foldable toward the back surface of the seat cushion.

〔Example〕

Hereinafter, the first and second embodiments of the seat according to the present invention will be described.
This will be explained in detail based on the figures. In addition, the third and fourth
The same parts as those in the figure are given the same reference numerals. 1st, 2nd
In the figure, a seat 1A is a front seat 4A and a rear seat 5A that are foldably connected to the vehicle floor 3 behind the bulkhead 2.
It consists of The front seat 4A has a connecting arm 8a that projects in the direction of the vehicle floor 3 from the upper end of the front legs 6 fixed to the vehicle floor 3 and the bottom 8B of the front portion 8A of the seat cushion portion 8.
The seat cushion part 8 is rotatable forward via a hinge part 7 formed by pivotally connecting the lower end of the seat cushion part 8 located closer to the rear than the front part 8A; Section part 8
A seat back part 10 is attached to the rear of the vehicle so as to be rotatable forward about a hinge part 22, a vertical part 23 that is integrated with the seat back part 10 and extends in three directions of the vehicle floor, and a vertical part 23 that extends along the vehicle floor 3 from this vertical part 23. Rear leg 25 consisting of horizontal portion 24 extending rearward
It is made up of. Further, the rear seat 5A has a front leg 26 whose lower end is pivotally supported to the rear end of the horizontal section 24 so as to be rotatable forward about a hinge section 29, and a seat cushion section 15 with the front leg 26 fixed to the front section.
A seat back part 17 is arranged at the rear of the seat cushion part 15 in a rearwardly tilted manner via a hinge bracket 28 and is rotatably connected to the front about a hinge 33; A rear leg 19 is provided at the rear lower part of the seat cushion section 15 and is foldable toward the rear surface of the seat cushion section 15 around a hinge section 18. Above rear seat 5A
The upright position of the seat bag 17 is ensured by engaging a pin 30 protruding from the seat bag frame 27 into a locking groove 31 cut into the hinge bracket 28. Reference numeral 32 designates a locking means consisting of a pin 30 and a hook member 35 which is pivotally supported in the upper vertical direction of the seat back portion 10 of the front seat 4A and has a locking hook portion 34 at its tip.

According to the above configuration, when folding the seat from the usage state shown in FIG. Superposition, second
As shown in Figure A, rotate the seat cushion section 15 forward together with the seat back section 17, align the back surface of the seat back section 17 of the rear seat 5A with the back surface of the seat back section 10 of the front seat 4A, and then press the hook member. 3
4 to the pin 30 and locking the locking means 32, the seat back part 10 of the front seat 4A is rotated forward about the upper hinge part 22 as shown in FIG. The seat cushion part 8 of the front seat 4A is rotated forward together with the seat back part 10 as shown in FIG. 2C, and the seat cushion part 8 of the rear seat 5A is End 15a rests on bulkhead 2. As a result, the front seat 4A and the rear seat 5A, in which the seat cushion parts 8, 15 and the seat back parts 10, 17 are superimposed, can be arranged vertically in a superimposed state. In addition,
