The present invention relates to a coupling structure of the seat frame for the bus, and in detail, the fasteners are attached to the outer circumferential surface of the seat frame, respectively, and the upper portion of the vertical member positioned below the seat frame to support the seat frame is When an error occurs in the joint between the seat frame and the vertical member by attaching the guide members to be inserted into the fasteners attached to the lower part of the seat frame to move the seat frame to the front and rear surfaces from the vertical member. In order to correct the error by properly adjusting the coupling position between the seat frame and the vertical member in the front and rear directions.

In general, a plurality of seats are installed in the interior of the bus in the longitudinal direction, such seats are to be supported by the seat frame made of steel to increase the safety for passengers, conventionally such a seat frame As shown in the figure, the seat frame S and the vertical member V are fixed by being integrally coupled with the vertical member V to be attached to the bottom of the room by welding.

However, the coupling structure 30 of the conventional seat frame as described above has a fixed coupling relationship with the vertical member (V), so when an error occurs in the coupling portion with the vertical member (V), the front and Since the distance between the seats adjacent to the rear side becomes narrow or extremely wide, the joint of the seat frame S and the vertical member V must be exactly matched, while the seat frame S and the vertical member V Many problems, such as a lot of manpower and work time required for the combination.

The coupling structure of the seat frame for a bus according to the present invention is devised in view of the above-described problems, and an object of the present invention is to couple the seat frame and the vertical member by movably coupling the seat frame and the vertical member. Even when an error occurs in the part, the mating position between the seat frame and the vertical member is properly adjusted in the front-rear direction so that the error can be corrected, thereby improving the completeness of the vehicle.

Features of the present invention for achieving the above object, the ring portion formed on the upper side of the channel-shaped fastener to the bolt is fastened by a screw hole formed in the inner side of the seat frame constituting the skeleton of the bus seat Attached through each, and the upper portion of the vertical member to support the seat frame is inserted into the inside of the fastener attached to the lower portion of the seat frame attached to the guide member of the rectangular cross section to guide the forward and backward movement of the seat frame It is made of a structure, when described in detail with reference to the accompanying structure of the seat frame for the bus according to the present invention as follows.

FIG. 2 is a perspective view of the present invention, and FIG. 3 is a cross-sectional view taken along the line AA of FIG. 2, wherein the coupling structure 10 of the seat frame for a bus according to the present invention is attached to the outside of the seat for the bus. On one side of the seat frame (S) to form the frame of the seat ring portion (2) formed in the upper part of the channel-like fastener (3) to fasten the bolt (1) by a screw hole (3A) formed on the inside Attached through each, and the fastener (3) attached to the lower portion of the seat frame (S) on the upper portion of the vertical member (V) positioned at the lower portion of the seat frame (S) to support the seat frame (S) It is made of a structure that is attached to the guide member 5 having a rectangular cross-section so as to be in close contact with the inside of the guide to guide the back and forth movement of the seat frame (S).

Referring to the operation and effects of the present invention as described above, the coupling structure 10 of the seat frame for the bus according to the present invention, the vertical member ( V) is fixed to the bottom of the room and installed in the interior of the bus. When an error occurs in the installation interval between the seat frame located on the front and back surfaces during the installation of the seat frame S and the vertical member V, In this case, the bolt 1 fastened to the screw hole 3A of the fastener 3 is relaxed to appropriately move the seat frame S back and forth. When the bolt 1 is relaxed in this manner, the fastener 3 of the seat frame S is loosened. ) Is able to move back and forth from the guide member 5 of the vertical member (V) it is possible to adjust the coupling position of the seat frame (S), the adjustment of the coupling position of the seat frame (S) by the above process After completion of the fixture (3) By strongly fastening like the bit 1 and the initial condition is to achieve a seat frame (S) and the combined relationship are fixed vertical member (V).

As described above, the coupling structure 10 of the seat frame for the bus according to the present invention, the seat frame (S) and the vertical member (V) by movably coupling the seat frame (S) and the vertical member (V) in the forward and backward direction If an error occurs in the engagement portion between (V), by adjusting the engagement position between the seat frame (S) and the vertical member (V) appropriately in the front and rear direction to correct the error, thereby improving the completeness of the vehicle, There is a lot of effects, such as to increase the latitude of the coupling position between S) and the vertical member (V) to facilitate the coupling between the seat frame (S) and the vertical member (V).

Claims (1)
