Embodiments of the present invention will be described below by assigning the same reference numerals to parts equivalent to those of the conventional device. In FIG. 1, a base 11 that is supported by a center turntable 10 and is rotatable in a horizontal plane is installed on a floor 1 of a vehicle, and a rail 12 that extends linearly in a substantially horizontal direction is provided on an upper surface of the base 11. A main seat 15 is connected via a leg portion 14 to a slide rail 13 which is fixed and combined with the rail 12.

A link base 3 is fixed to an arm 16 extending obliquely downward from the main seat 15 with a small clearance from the floor 1, and two lower ends of the links 4 and 5 are pivotally supported by the link base 3, respectively. The upper ends of the auxiliary seats 6 are pivotally attached to the lower surfaces of the auxiliary seats 6 so that the auxiliary seats 6 are supported by the link base 3 in the same manner as in the conventional device, and the links 4 and 5 are rotated to move the auxiliary seats 6 from the use state in the figure. Rotate in the direction of the arrow and move it in sequence as shown by the chain double-dashed line,
It is configured so that it can stand on the side of 5.

As shown in FIG. 2 in which the essential portions are extracted, a transmission member 21 is pivotally supported by a shaft 22 on an abutment 20 whose lower surface is fixed to the link base 3, and a transmission member 21 is also provided. 2 is urged clockwise by the return spring 23 in FIG. 2 and held upright by the stopper 20a. Further, the link base 3 extends to the full width in the small gap between the link base 3 and the floor 1. The bracket 24 is disposed on the link base 3 by the shaft 25 substantially horizontally, and is urged clockwise by the return spring 26 in the clockwise direction of FIG. 2 to be held upright by the stopper (not shown). Rubber damper 2 fixed to the lower surface of 24
In the state shown in the figure, the auxiliary sheet 6 is in contact with the floor 1
It is able to support the weight of the occupants sitting on it.

On the other hand, operating levers 28 and 29 are pivotally or slidably attached to the left and right side surfaces of the main seat 15, respectively, and one ends of wire cables 30 and 31 are connected to the operating levers 28 and 29, respectively, and the wires are connected. The other ends of the cables 30 and 31 are connected to the left and right wall portions 32 and 33 of the transmission member 21, respectively, and the other end of the wire cable 34 whose one end is connected to the right wall portion 33 is connected to the upper end of the bracket 24. There is.

Therefore, if one end of the wire cable 30 is pulled by rotating or pulling the one operating lever 28, the left wall portion 32 of the transmission member 21 is pulled by the wire cable 30 and the transmission member 21 is returned to the return spring. Since it rotates on the shaft 22 in the counterclockwise direction in FIG. 2 against the biasing force of 23, the wire cable 34 having one end connected to the right wall portion 33 is pulled, and the upper end of the bracket 24 is pulled. As a result of the bracket 24 rotating counterclockwise in FIG. 2 on the shaft 25 against the urging force of the return spring 26, the rubber damper 27 on the lower surface of the bracket 24 is fixed to the floor as shown by the chain double-dashed line in FIG. 1 or separate the rubber damper 27 from the floor 1

For this reason, the main seat 15 together with the auxiliary seat 6 supported on the link base 3 can be easily rotated in any direction on the turntable 10 and / or the slide rail 13 can be slid along the rail 12. It is possible to easily perform linear displacement in the front-rear direction or the like, and after the main seat 15 is displaced as desired, if the operator releases the operating lever 28 or the operating lever 29, the return spring 23 and the return spring 26 can be moved. Each part is returned to the original state by the urging force, and the rubber damper 27 on the lower surface of the bracket 24 comes into contact with the floor 1 again, so that the weight of the occupant sitting on the auxiliary seat 6 can be supported.

That is, even if the auxiliary seat 6 to be seated on the floor 1 is attached to the main seat 15, the main seat 15 can be easily rotated horizontally or slid in the front-rear direction or the like as required, so that comparison is made. The main seat 15 can be freely and variously used even in a narrow vehicle compartment, which is practically very convenient.

In the above embodiment, the bracket 2
Even when 4 is not grounded to the floor 1, the link base 3 also serves as a reinforcement for the mounting portion of the auxiliary seat 6, so that the weight of the auxiliary seat 6 can be sufficiently supported. Further, in the above-described embodiment, the wire cable 34 is connected to the upper end of the bracket 24 so that the bracket 24 can rotate. However, the wire cable 34 is connected to the lower portion of the bracket 24 to connect the bracket 24 to the bracket 24. The bracket 24 can be rotated in the opposite direction to the above, or the bracket 24 can be slid vertically with respect to the link base 3, and the bracket 24 can be pulled upward by the pulling force of the wire cable 34. However, it goes without saying that the same effects as those of the above embodiments can be obtained.

Further, as shown in FIG. 3, the operating lever and the wire cable 3 are pivotally supported by the link base 3.
Even if the attachment of the rubber damper is omitted by making the lower end of the bracket 24 driven by an operation mechanism such as 4 into a shoe shape and abutting it on the floor 1, the same operational effect as that of the above-described embodiment can be obtained. Is something that can be done.

[0017]

In the vehicle seat according to the present invention, even if the link base for supporting the auxiliary seat which can be erected sideways of the main seat is attached to the side portion of the main seat, the link base is installed from the floor. Since the brackets are arranged at intervals and the brackets are driven by the operation mechanism to move the brackets away from the floor, the brackets cannot be slid relative to the floor when the main seat is displaced on the floor. Since it is possible to surely eliminate or reduce the movement, it becomes possible to easily rotate or displace the main seat together with the auxiliary seat, and it becomes very convenient in practice.
