Description

[Detailed Description of the Invention] a. Field of Industrial Application The present invention relates to an automobile seat, and particularly to an improvement of an automobile seat that enables a full flat seat structure in a small car with a narrow interior.

b. Prior art Large passenger cars or full cab wagons (one-box cars), etc. have a front seat 1 and a rear seat 2 as shown in Figure 1.
Since the distance L between the front seat 1 and the front seat 1 is large, a fully flat seat can be constructed by tilting the seat back 3 of the front seat 1 backward so that it becomes almost horizontal using the reclining device 4 and connecting it to the rear seat 2. However, in the small car 5 where the distance L is narrow, it is difficult to obtain a fully flat seat with the same seat structure as that of a large car. For this reason, it is necessary to have a complicated seat sliding structure that moves the front seat 1 forward by more than the practical seat sliding amount, a special high headrest with a high back, and a special seat back structure (low back seat) with a removable pillow. However, as a result, there was a drawback that the cost of the product increased. Therefore, conventionally, the seat back 3 of the front seat 1 is tilted backward to the position shown by the chain line in FIG. 1 using the reclining device 4, and
The lower part 6b of the seat back 6 of the rear seat 2 is lifted using its upper part 6a as a fulcrum and rotated to the position shown by the chain line, thereby forming a fully flat seat.

However, with such a conventional configuration, not only is it not possible to obtain a completely flat seat, but also the seat back 6 cannot be folded forward and used as a loading platform, so it cannot be used in a two-box type vehicle. There was a problem.

c. Purpose of the invention The purpose of the invention is to provide an automobile seat that solves the problems of the above-mentioned prior art.

d Structure of the invention The feature of the invention is that in an automobile seat in which the seatbacks of the front and rear seats are configured to be able to rotate almost vertically and horizontally with respect to the front seat and the rear seat, the tilting fulcrum of the rear seatback is A support body is disposed above the rear seat and between the rear seat seat back and the cargo bed, and the rear seat back is configured to be rotatable around its lower part, and the front and rear seat backs By tilting the front seat back backwards and connecting the front seat back to the rear seat seat back, the rear seat seat back and the front seat seat back are formed substantially horizontally and on the same plane.

e Embodiment Figures 2 to 4 show one embodiment of the present invention. In the figures, 1 is a front seat, 2 is a rear seat, and 3 is a seat that is attached to the front seat 1 so that it can be raised and folded. A front seat back; 4 is a reclining device for enabling the front seat back 3 to be raised and folded; 5 is a small passenger car; 6 is a rear seat back that is attached to the rear seat 2 so that it can be raised and folded; 7 is a rear seat back 6 8 is the rear seat back 6.
A striker pin 9 protrudes from both sides of the vehicle; 9 engages with the striker pin 8; and 11 is a seat back locking device provided on the vehicle body 10 side to maintain the upright position of the rear seat seat back 6; be.

The support body 7 is disposed above the rear seat 2 and between the rear seat back 6 and the cargo platform 11, and the support plate 12 is rotated to the end of the L-shaped base body 14 via a pin 13. Combine freely. The abutment plate 12 is fixed to the lower back surface 15 of the rear seat back 6, and the base 14 is fixed to the front surface 16 of the cargo platform 11, so that the rear seat back 6 can be raised and folded back and forth around the lower part thereof. It is set as.

As shown in FIGS. 3 and 4, the seat backlock device 9 includes a lock lever 19 and a fork lever 20 rotatably attached to the upper surface of a lock body 17 by a pivot pin 18. A coil spring 21 is wound around the pivot pin 18 between the lock body 17 and the lock lever 19, and one end of this coil spring 21 is attached to the lock body 17.
The other end is fixed to a lock lever 19. The lock lever 19 is biased by a coiled spring 21 so that its engaging portion 22 rotates clockwise. Further, engagement grooves 23 and 24 are formed in the upper and lower parts of the fork lever 20, the engagement groove 23 engages with the engagement portion 22 of the lock lever 19, and the engagement groove 24 engages with the striker pin 8. It is configured to match. Projections 25 are formed on both sides of the upper part of the fork lever 20, and the other end of a coiled spring 26, which has one end fixed to the lock body 17, is fixed to one of the projections 25. The fork lever 20 is biased by a coil spring 26 to rotate clockwise.

FIG. 4 shows the rear seat back 6 in an upright state. From this state, when the lock lever 19 is rotated counterclockwise against the elastic force of the coiled spring 21 to the position shown by the chain line, the engagement portion 22 comes out of the engagement groove 23, and at the same time, the fork lever 20 is rotated clockwise by the coil spring 26 as shown by the chain line, so the striker pin 8 comes out of the engagement groove 24 as shown by the chain line, and the striker pin 8 comes out of the engagement groove 24 as shown by the chain line. The seat back 6 can be folded back and forth.

f. Effect To obtain a fully flat sheet with the configuration of the present invention, the following operation is performed.

First, the lock lever 19 is pulled forward to remove the striker pin 8 from the seat back lock device 9, and then the rear seat back 6 is rotated rearward about the support 7 to the position indicated by the chain line 6' and brought down. As a result, the rear seat back 6' is set in a substantially horizontal state. Next, the front seat back 3 is tilted back to the position indicated by the chain line 3' by the reclining device 4, and is connected to the rear seat back 6', which is in a substantially horizontal state, so as to be on the same plane.

By operating in this manner, a fully flat seat is constructed from the front seat 1, the front seat back 3' and the rear seat back 6'.

In addition, if the rear seat back 6 is rotated forward using the support 7 as a fulcrum to the position indicated by the chain line 6', then
The back of the rear seat back 6'' can be used as a cargo platform.

In this example, the application was applied to the seats of a two-row seat type car, but the application is not limited to this.
It is also possible to apply the present invention to the third and second rows of row seat type automobile seats.

g. Effects of the invention As described above, in the automobile seat according to the invention, the support that serves as the fulcrum for raising and lowering the rear seat back is arranged above the rear seat and between the rear seat back and the cargo bed. Since the rear seat back is configured to be rotatable around its lower part, a step is formed between the rear seat back and the rear seat when the rear seat back is folded back. Therefore, when the front seat back is folded back and connected to the rear seat back, the front seat back and the rear seat back become almost horizontal to the same plane, even in small passenger cars where the distance between the front and rear seats is narrow. A fully flat sheet can be obtained quickly with very simple operations. In addition, the seat of the present invention has a simple structure, and there is no need to install a special seat slide device on the front seat or make the front seat a low-back seat, so there is no need to increase the cost of the product. It is extremely advantageous economically. In addition, depending on the position of the support, even when the rear seat back is folded forward and used as a cargo platform, the back of the rear seat back and the cargo platform are almost horizontal, making it easy to load and unload cargo easily and quickly. It also makes it possible to carry a lot of luggage.
