Description

[Detailed description of the invention] [Technical field of the invention]

The present invention relates to a seat used in a vehicle, and more particularly to a seat that allows a normal seat to be used as a two-way seat with simple operation.

[Prior art and its problems]

BACKGROUND ART In automobiles such as wagons and vans, there has been a desire for a seat that can be converted into a facing seat when resting. For this reason, a vehicle has also been developed in which the front seat is extended rearward to face the rear seat. However, the reality is that all of these conventional seats have complex configurations and have not yet been developed to allow for easy switching operations.

[Purpose of the invention]

It is an object of the present invention to have a simple mechanism and to be able to easily convert the seat into a two-person seat.

[Structure of the invention]

The seat of the present invention has a reclining device in which a pair of seat cushions are arranged side by side and a seat back can be tilted with respect to the seat cushions, the pair of seat cushions being a substantially rectangular seat cushion body. It is composed of the front part of the seat cushion main body and a hook-shaped rotating corner facing the two opposite sides of the central side, and the part of both rotating corners corresponding to the front part of the seat cushion main body is The cushion body is configured so that they can be rotated in the direction of expanding each other using the outer ends as rotation fulcrums to face each other, and the center portion of the seat bag is removable to form a cushion body. A pair of shallow container-shaped openings are formed in the seat bag, and the cushion body is inserted into a space formed by both rotating corners of the seat cushion and the seat cushion body when the rotating corners of the seat cushion face each other. When inserted, a new seat bag is constructed, and when the seat bag is tilted flat with respect to the seat cushion, the shallow container-shaped opening can be configured as a side table, thereby forming a seat-type seat. It is characterized by being able to be formed.

[Embodiments of the invention]

FIG. 1 shows a vehicle rear seat to which the present invention is applied. In the figure, reference numeral 1 denotes a pair of seat cushion bodies supported by legs 2. The cushion bodies 1 have a substantially rectangular shape. A seat cushion is constructed by allowing insertion of opposing hook-shaped rotating corners 3 on two sides of the seat cushion. The rotating corner 3 is
90 degrees from each other around a fulcrum shaft 4 provided at the outer end of a portion corresponding to the front part of the seat cushion body 1.
It has an L-shape that allows it to rotate and face each other in the direction of tilting and expanding. A bench seat type seat back 5 is arranged on the back of the seat cushion body 1. The seat bag 5 has a structure that allows it to be unfolded from the state shown in the figure to a substantially horizontal state by means of a reclining device 6 provided on the side. The seat back 5 has a pair of shallow container-shaped openings 7.
A cushion 8 is removably fitted into the opening 7. A semicircular groove 9 is formed approximately in the center of the cushion 8, and a cushion fixing lever 10 is rotatably disposed within this groove 9. Cushion 8
Inside, the lever 10 is provided with a toggle mechanism 11 that is perpendicular to each other at 90 degrees, and a stopper pin 12 connected thereto projects from the side of the cushion 8 at an orthogonal angle of 90 degrees. Further, reference numeral 13 is a locking device provided on the lower edge of the cushion 8. In the cushion 8 having the above structure, stopper holes 3a and 3b are formed at an angle of 90 degrees on the inner side of the rotating corner 3, and furthermore, the engagement holes 3a and 3b are formed at the rear of the seat cushion 1. Stop 13
A locking pin 14 for hooking and locking is provided protrudingly. In order to rearrange the rear seat configured as described above into a two-person seat, first remove the cushion 8 from the seat bag 5, and then operate the doubler 6 in the reclining position to rotate it to a horizontal position as shown in Figure 2. , the rotating corner 3 is rotated about the fulcrum shaft 4 into a substantially upright state. Rotating corner 3
is locked in that position. FIG. 4 shows its rotation and locking mechanism. In the figure, a movable frame 30 installed in the rotating corner 3 is rotatably supported by a fixed frame 20 on the seat cushion 2 side with respect to the fulcrum shaft 4. A gear 40 concentric with the fulcrum shaft 4 is fixed to the fixed frame 20. The other end of the hooking piece 31 is connected to the movable frame 30 by a shaft 32 on the gear 40.
The gear 4 is always supported by a spring 33.
It is biased in the zero meshing direction. Also, the hooking piece 3
A knob 34 is fixedly installed near the movable frame 30 and protrudes to the outside through an arcuate elongated hole 35 formed in the movable frame 30. Therefore, when the knob 35 is moved along the elongated hole 35, the locking piece 31 and the gear 40 are separated, and in this state, the movable frame 30 (and therefore the rotating corner 3)
can rotate about the fulcrum shaft 4 as the center of rotation, and can bring about the rotating corner 3. Further, when the knob 34 is turned, the latch piece 31 meshes with the gear 40, so that it can be locked in that position. Next, the removed cushion 8 is fitted into the space formed between the seat cushion body and the rotating corner 3, the locking tool 13 is attached to the locking pin 14, and the fixing lever 10 is then rotated. This causes the stopper pin 12 to protrude into the stopper holes 3a and 3b. Through the above operations, a new seat bag is constructed by the rotating corner 3 and the cushion 8 as shown in FIG.
The seats face each other, forming a pair of seats. When the original seat bag 5 is pulled down horizontally, it constitutes a side table with the opening 7 serving as a tray.

【Effect of the invention】

As explained above, according to the present invention, by adjusting the folding direction of the seat cushion and seat bag, it is possible to convert the seat from a normal operating state to a facing seat with a simple operation.
