[0008]

[Effects of the Invention] Each cantilever support device 1 configured as described above.
00 has the following actions, but the cantilever support device 100 according to claim 2 substantially includes the cantilever support device 100 according to claim 1, and therefore the cantilever support device 100 according to claim 2 will be described below. The operation of the cantilever support device 100 will be mainly described.

First, in this cantilever support device 100, whether the vehicle seat 200 is for one person or for a plurality of people, the load applied thereto is the lever member 40 attached to the lower surface thereof. Through the cantilever support device 100
The vertical support arm 20 and the tilt arm 30
Will be lost. Since the vertical support arm 20 and the tilted arm 30 are integrated with the support base 10 fixed to the floor surface opposite to the passage of the vehicle, the load of the vehicle seat 200 can be applied to the support base 10. It will hang on the part of the floor opposite to the passage. Therefore, the vehicle seat 200 is cantilever-supported on the floor surface opposite to the aisle by the support base 10 fixed in this way, and the vehicle seat 200 is provided below the aisle side portion. Therefore, a large free space as shown in FIG. 1 is secured.

At this time, since the lever member 40 is supported by the vertical support arm 20 and the tilt arm 30 tilting toward the free space side, for example, when only one person sits on the passage side. Even if the load is ubiquitous on the vehicle seat 200, the load is always applied on the support base 10 without being largely biased.
Further, since the shape of the support base 10 is considerably smaller than the lateral width of the vehicle seat 200, the free space formed in the aisle side portion of the vehicle seat 200 is sufficient for accommodating feet and luggage. It has a large size.

Particularly, the cantilever support device 100 according to claim 2.
In the above, the support base 10 is mainly used as the positioning support base 1
Since it is composed of 1 and the connecting support 12, its assembly is easy as follows. That is, the positioning support base 11 has a gate shape having a small width and an insertion connection port 11a.
After fixing 1 to the floor surface, the connection support 12 is
For example, since it suffices to insert and connect from the aisle side, the work of fixing the vehicle seat 200 to the floor surface is simple.

Specifically, the positioning support base 11 is placed on the floor surface.
And the positioning pin 50 are fixed, while the lever seat 40 and the tilt arm 30, and the vertical support arm 20 and the tilt arm 30 are integrally connected to the lower surface of the vehicle seat 200. Since the connection support bases 12 are assembled respectively, these operations can be performed without being disturbed by the existence of the vehicle seat 200.
Then, the projection 12a of the connection support base 12 integrated on the vehicle seat 200 side is inserted into the insertion connection opening 11a of the positioning support base 11 already fixed on the floor surface,
The positioning of the vehicle seat 200 with respect to the floor is completed by engaging the head 51 of the positioning pin 50 on the floor with the engagement groove 13 formed in the lower surface of the connection support base 12. After that, as shown in FIG. 4, if each fixing bolt 14 is inserted into the connection support base 12 and then screwed to the positioning support base 11, the connection support base 12 is connected to the positioning support base 11. Completed, vehicle seat 20
0 is firmly fixed on the floor through this support 10.

According to the cantilever support device 100 as described above, the load from the vehicle seat 200 side is mainly applied from the inclined arm 30 to the support base 10 side, and the load is used to form the support base 10. A rotating force centering on 12 will work. However, this torque is
Since it is completely canceled by the positioning support base 11 fixed on the floor surface, the supporting and fixing state of the vehicle seat 200 becomes stable. The force applied when the vehicle swings up and down is sufficient due to the fitting of the projection 12a of the connection support base 12 to the insertion connection port 11a and the fixation of the connection support base 12 to the positioning support base 11 by each fixing bolt 14. The force in the front-rear direction of the vehicle seat 200, which is caused by acceleration or deceleration of the vehicle, is prevented by the engagement groove 13 of the connection support base 12 and the positioning pin 5.
It is prevented by the engagement with 0.

In the embodiment described below, the connection between the vertical support arm 20 and the lever member 40 is adjusted by the adjusting screw 2.
2 and the adjustment screw 22 has threaded portions on both sides of the handle portion 22a, each of which has a reverse thread. Therefore, by rotating the handle portion 22a, the lever member 40 is vertically supported. The height of the arm 20 can be freely adjusted.
