Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a double seat installed in a vehicle such as an automobile.

[Conventional technology]

Conventionally, in a seat 1 in which the seat part 2 and the backrest part 3 are hinged as shown in Fig. 6, the backrest part 3 is folded all the way backward as shown by the dotted line to be in a fully flat state and used for a bed, etc. However, when the seat 1 is placed in a fully flat state, the space above the seat 1 is wasted.

[Means to solve the problem]

The present invention, as a means to solve the above-mentioned conventional problems, hinges the upper backrest part 13 to the upper seat part 12 so as to be rotatable until it becomes a fully flat state, and the lower backrest part 15 to the lower seat part 14. The upper seat part 1 is hinged so that it can rotate until it is in a fully flat state.
2 on the lower seat part 14, and the upper backrest part 13 on the lower backrest part 15,
The root ends of a pair of left and right L-shaped armrests 16 are pivotally attached to both sides of the front part of the lower seat part 14, and the hinge parts of the upper seat part 12 and the upper backrest part 13 are attached to the tips of the armrests 16 on both sides. A pair of left and right stays 17 are provided upward from both sides of the rear portion of the lower seat portion 14, respectively.
The upper backrest portion 13 is located at the tip of the stay 17.
This provides a double seat with both upper sides pivotally connected.

[Effect]

In use, the upper seat part 12 and the lower seat part 14 overlap, and the upper backrest part 13 and the lower backrest part 1
5 in an upright state. Upper backrest part 13
are supported by a pair of left and right stays 17 extending from both rear sides of the lower seat portion 14. When creating a two-tiered bed, the lower backrest 15 is rotated backward to bring it into a fully flat state, and the upper backrest 13 is rotated upward together with the upper seat 12 around the pivot point of the stay 17. The upper backrest portion 13 is rotated to the fully flat state, and the pair of left and right armrests 16 are further rotated upward about the pivot portion, and the receiving portion 26 at the tip of the armrest 16 is placed in the upper side of the fully flat state. The pins 23 extended from both sides of the hinge parts of the seat part 12 and the upper backrest part 13 are received respectively.

[Effect of idea]

Therefore, in the present invention, since a fully flat seat is placed above the fully flat seat, the space above the lower seat can be effectively utilized.

〔Example〕

To explain the present invention with reference to an embodiment shown in FIGS. 1 to 5, the seat 11 has an upper seat part 12 and an upper backrest part 13 mutually hinged, and a lower seat part 14 and a lower backrest part. The upper seat part 12 and the upper backrest part 13 are hinged together with the lower seat part 14.
It has a double structure in which the upper and lower backrests 15 are overlapped, and the root ends of a pair of left and right L-shaped armrests 16 are pivotally attached to both sides of the front part of the lower seat 14, and A pair of left and right stays 17 are extended upward from both sides of the rear portion of the side seat portion 14.
The upper backrest part 13 is connected to the tip of the
Both sides of the upper part are pivoted.

Hinges 19 as shown in FIG. 2 are interposed on both sides of the upper seat part 12, upper backrest part 13, and hinge part, respectively, and the hinges 19 are composed of a seat part side arm 20 and a backrest part side arm 21. , the arm 2
0 and the arm 21 are hinged to each other via a shaft 22, and the shaft 22 is extended to form a pin 23.
Furthermore, a pin 24 is provided protruding from the arm 21, and the pin 24 is slidably fitted into a guide groove 25 of the arm 20, so that the upper backrest portion 13 of the arm 21 is moved from the upright state shown by the dotted line in FIG. 2 to the state shown by the solid line. The rotation of the upper seat part 12 and the upper backrest part 13 is guided and restricted until they become fully flat. A receiving portion 26 for the pin 23 of the hinge 19 is formed at the tip of the armrest 16. A rear bracket 27 is attached to both rear sides of the lower seat part 14, and an arm 28 of the lower backrest part 15 is pivotally connected to the rear bracket 27 via a shaft 29.
0 is extended and the pin 30 is attached to the rear bracket 27.
The arm 28 is slidably fitted into the guide groove 31 of the arm 28.
From the upright state of the lower backrest 15 shown in solid lines in Figure 1, the lower seat 14 and lower backrest 1 shown in dotted lines
The lower backrest 15 is designed to guide and restrict the rotation of the lower backrest 15 until the lower backrest 15 is in a fully flat state.
5. The pins 32 protruding from both sides of the upper part are attached to the lower seat part 1.
It is engaged by a hook 34 attached to a bracket 33 on the upper part of the stay 17 extending from the stay 17. Furthermore, the rear bracket 27 of the lower seat portion 14
A hook 35 is attached to the upper part, which engages the pin 24 of the arm 21 of the upper backrest part 13.
A root end 36 of the armrest 16 is pivotally connected to front brackets 38 on both sides of the front of the lower seat 14 via a shaft 37, and a locking groove 39 is formed in the root end 36. An engaging piece 40 attached to the bracket 38 is engaged with the locking groove 39 to prevent the armrest from rotating upward from the state in which the armrest is used as shown in FIG. The distal end portion of is received by a receiving piece 41 extended from the stay 17.

In the above configuration, when the seat 11 is used as shown in FIG.
The pin 24 of the arm 21 is engaged with the hook 35 of the rear bracket 27 of the lower seat part 14, and the pin 32 of the lower backrest part 15 is engaged with the hook 34 of the stay 17.
The engagement piece 40 of the front bracket 38 of the lower seat part 14 is engaged with the engagement groove 38 of the base end 36 of the armrest 16. Then the stay 1

The lower seat 14 and the lower backrest 15 are disengaged from each other and rotated backward.
and the hook 35 of the rear bracket 27 of the lower seat part 14 and the upper backrest part 1.
3, and release the engagement between the locking groove 39 of the root end 36 of the armrest 16 and the engagement piece 40 of the front bracket 38 of the lower seat 14, The upper backrest part 13 is connected to the upper seat part 1
2 and the stay 17 is rotated upward about the shaft 18 at the tip of the stay 17, and the upper backrest 13 is rotated relative to the upper seat 12, so that the upper seat 12 and the upper backrest 13 are in a fully flat state. Then, the pair of left and right armrests 16 are respectively rotated upward so that the pins 23 of the hinges 19 of the upper seat part 12 and the upper backrest part 13 are received by the receiving parts 26 of the armrests 16, respectively. In this way, a two-tiered bed as shown in FIG. 3 is formed.

In the above embodiment, a two-tiered bed was formed by one sheet 11, but as shown in FIG.
