Description

[Detailed Description of the Invention] The present invention mainly relates to a seat installed in a van-type vehicle. It is desirable that this type of seat has the flexibility to change its direction forward or backward depending on the situation, or to change from a two-person seat to a three-person seat.

The present invention aims to meet the above-mentioned requirements, and its main feature is to extend one of a pair of seats rotatably arranged side by side on a base to accommodate two people.

To explain the present invention with reference to an embodiment shown in the figure, the rails 1, 1, 11, laid on the foundation G,
Bases 2 and 12 are slidably mounted on 11,
Seats 3 and 13 are rotatably installed on the bases 2 and 12. Seats 3 and 13 are seat parts 3A and 13A,
Backrest parts 3B, 13B are attached to the seat parts 3A, 13A so as to be reclinable, headrests 3C, 13C are attached to the upper part of the backrest parts 3B, 13B, and seat parts 3A, 13.
Armrests 3D, 1 attached to both sides of A
Consists of 3D.

If the seats 3 and 13 are rotated backwards, the state shown in FIG. 2 will be obtained. If the inner armrest 3D of one seat 3 is folded sideways, it becomes an extension of the seat part 3A, and if the inner armrest 13D of the other seat 13 is removed, it becomes the backrest part 3B of one seat 3.
It is attached to the side surface and serves as a backrest portion of the seat extension. Thus, as shown in FIG. 3, one of the seats 3 is extended to accommodate two people.

As shown in FIGS. 4 and 5, the armrests 3D, 13D have a plurality of insertion rods 5 that can be bent 90 degrees from the mounting side.
When using D as an extension of the seat parts 3A, 13A and backrest parts 3B, 13B of the seats 3, 13, insert the insertion rod 5 into the armrest 3D, as shown in FIG.
Stretch out horizontally to 13D and seat 3A, 13A
The insertion rod 5 is inserted into the plurality of insertion holes 3'A, 3'B provided on the mounting side of the backrest parts 3B, 13B, and when the armrest is used for its original purpose, the insertion rod 5 is inserted into the armrest 3D, as shown in FIG. against 13D
Bend it 90 degrees to make it vertical, and insert it into the insertion holes of the seats 3A and 13A.

In order to make the insertion rod 5 bendable by 90 degrees, the configuration shown in FIGS. 6 and subsequent figures is applied to the insertion rod 5, for example. In FIG. 6 and FIG. 7, 4 is a side frame of the armrest 3D, 13D, and the root end portion 5A of the insertion rod 5 is extended to the side frame 4.
One end of a connecting rod 7 is pivotally connected to the groove 5'A at the end of the connecting rod 7 by a pivot pin 6. An elongated hole 7A is provided at the other end of the connecting rod 7, and a pivot pin 8 of the tip portion 5B having a groove 5'B at the end of the insertion rod 5 is fitted into the elongated hole 7A. The tip portion 5B is hollow and has a built-in spring 10 fixed at one end with a pin 9, and the other end of the spring 10 is fixed to the end of the connecting rod 5. Thus, the tip portion 5B is It is urged in the direction of the root end portion 5A.

In the above configuration, armrests 3D, 13D
When used as a proper armrest, the tip portion 5B of the insertion rod 5 is bent at right angles to the position shown by the dotted line in FIG. 7 against the elasticity of the spring 10. In addition, the armrests 3D and 13D are attached to the seats 3 and 13 of the seats 3 and 13.
A, when used as an extension of 13A or as a backrest of the extension part, the tip part 5B of the insertion rod 5
Stretch horizontally to the position shown by the solid line in Figure 7.

Since the present invention has the above configuration, the seat can be rotated on the base to face forward or backward, and the armrest of the seat can be used as an extension of the seat or backrest to seat two people. This provides the desired versatility as a seat for a van-type vehicle or the like.
