In the cantilever support device 100, the vehicle seat 200
Is applied to the cantilever support device 100 via the lever member 20 attached to its lower surface, regardless of whether it is for one person or for multiple persons. Since the cantilever support device 100 is fixed to the inner wall surface on the side opposite to the vehicle passage, the vehicle seat 20
The zero load is applied mainly to the inner wall surface of the vehicle via the cantilever support device 100. Therefore, the vehicle seat 200 is cantilevered on the floor opposite to the aisle by the cantilever support device 100 fixed in this manner, and the vehicle seat 200 is below the aisle-side portion of the vehicle seat 200. A large free space as shown in FIG.

Since it is supported by the receiving arm 11 of the support body 10, for example, when only one person is seated on the passage side,
Even if the load is ubiquitous on the vehicle seat 200, the load is always applied to the wall without largely biasing. Since the shape of the cantilever support device 100 is considerably smaller than the width of the vehicle seat 200, the free space formed in the passage-side portion of the vehicle seat 200 is a space for storing feet and luggage. It is of sufficient size.

In particular, the cantilever support device 100 according to the present invention.
In the above, the stopper portion 12 is integrated with the upper end portion of the support body 10 to form an insertion portion 13 into which the end of the lever member 20 can be inserted between the stopper portion 12 and the receiving arm 11. Lever member 2
The end of the vehicle seat 20 may be inserted and connected to the insertion portion 13 from, for example, the passage side.
The fixing work for the zero vehicle has been simplified.

Specifically, first, the support body 10 of the cantilever support device 100 is fixed at a predetermined position on the wall of the vehicle. This attachment is provided on a mounting plate of the support body 10 constituting the side surface of the wall. This is performed using the mounting holes 16. In the embodiment shown in FIG. 1, the support main body 10 is mounted on a mounting rail 50 or the like which is fixed to the inner surface of the vehicle wall in advance by using bolts or the like. In order to secure a storage space for the mounting rail 50, the supporting body 10 of the embodiment has the step 14 formed on the end face on the wall side, but the step 14 is not always necessary. .

On the other hand, the lever member 20 is previously fixed to the lower surface of the vehicle seat 200 in a factory or the like where the vehicle seat 200 is manufactured, and the end of the lever member 20 is attached to the support body 10. It is inserted into the insertion section 13. At this time, the wedge plate 30 is provided between the distal end portion of the receiving arm 11 of the support body 10 and the insertion portion 13.
Is to intervene. Then, after the wall-side end of the lever member 20 is inserted into the insertion portion 13 of the support main body 10, the end of the lever member 20 is positioned so as to be securely locked to the stopper portion 12 of the support main body 10. Then, the lever member 20 is placed on the wedge plate 30 and temporarily fixed to the receiving arm 11 with bolts or the like. At this time, if the lever member 20 does not appear to be substantially horizontal with respect to the floor of the vehicle, the wedge plate 30 is moved in and out to adjust the lever member 20 horizontally. Since the wedge plate 30 has a literal wedge shape as shown in FIG. 2, the above adjustment can be easily performed. When the position adjustment of the lever member 20 is completed, the temporarily fixed bolts and the like are fully tightened, so that the support and fixing of the vehicle seat 200 to the vehicle wall by the cantilever support device 100 is completed.

In the fixing operation as described above, the fixing of the support body 10 to the wall side and the fixing of the lever member 20 to the vehicle seat 200 side are performed separately, and finally the lever member 2 is fixed.
0 can be fixed to the support body 10, so that each operation can be performed in a wide place and without much skill, so that it is very easy as a whole. is there. In the following embodiment, the support leg 40 fixed to the floor is fixed to the tip of the receiving arm 11 in order to more securely fix the support body 10 to the vehicle. However, since the fixing of the support leg 40 to the floor surface and the connection to the support main body 10 are simple, even when the support leg 40 is used, the cantilever support device 100 of the vehicle seat 200 is used. The supporting and fixing work is easy.

According to the cantilever support device 100 as described above, the load from the vehicle seat 200 is mainly applied from the lever member 20 to the receiving arm 11 on the cantilever support device 100 side. 100, the rotational force about the wedge plate 30
Will work. However, since this rotational force is completely canceled out by the stopper portion 12 constituting the support main body 10, the support fixed state of the vehicle seat 200 is stable against the wall. The force applied when the vehicle swings up and down is sufficiently prevented by the fitting of the support body 10 to the insertion portion 13 and the fixation of the support body 10 itself to the wall. Alternatively, the same applies to the longitudinal force of the vehicle seat 200 caused by the deceleration.
