[0002]

2. Description of the Related Art Conventionally, as a guide seat or the like having a seat belt, a flip-up seat is installed in a passenger compartment of a bus, and the seat belt of the flip-up seat or a locking device for the belt is stored on the floor surface of the bus. A seatbelt mounting structure for a flip-up seat in which a possible recess is formed is disclosed (Japanese Utility Model Laid-Open No. 54-68322). The seat belt is a two-point seat belt that restrains the waist of a seated person. With this seatbelt mounting structure, the seatbelt of this seat and the belt locking device can be stored under the same plane as the floor when the seat is lifted up without using the flip-up seat. Never be. Further, by mounting an opening / closing lid that forms the same plane as the floor surface in the recess, it is possible to prevent stains on the seat belt and the like.

On the other hand, a cushion pad of the seat cushion is partially cut out on the seat belt mounting side of the seat cushion, and an auxiliary seat used in a vehicle in which a seat belt retractor is housed in the cutout portion. Is disclosed (Actual Kaihei 1-65727). The seat belt is a two-point seat belt that restrains the waist of a seated person. With this auxiliary seat, a seatbelt with a retractor can be easily attached to this seat, folding and storing of this seat are easy, and further, it is possible to avoid hanging of the seatbelt when folding or storing this seat. It has become.

[0004]

However, the above-mentioned conventional seat belt attachment structure for flip-up seats and seat belts for auxiliary seats used in automobiles are both two-point seat belts for restraining the waist of a seated person. Therefore, there was a problem that the seat restraint performance was relatively low. The object of the present invention is to improve the restraint performance of the occupants of the guide seats, not to impair the appearance of the front of the cabinet, and to prevent the guide seats from getting in and out when the guide seats are not used. It is to provide a bus that they have.

7 has an inner belt 34 attached to the front surface of the belt 7 and provided with a buckle 33 at its tip, and a tongue plate 36 loosely fitted to the webbing 32 and detachably locked to the buckle 33 (FIGS. 1 to 5). As shown in detail in FIG. 3, the lower cabinet 17 includes a cabinet body 17b having a fuel tank 37 inserted therein and a cabinet body 17b.
It has a cover part 17c that covers the front surface of the cabinet body 17b at a predetermined distance from the front surface of b.

A lower reinforcing plate 38 is welded to one side, that is, the right side of the guide seat 19 from the step 13 toward the front surface of the cabinet 16 in the lower part of the rear surface of the front wall 17d of the cabinet body 17b. The nut 38a is welded. The lower bracket 39 is fixed to the lower part of the front surface of the front wall 17d of the cabinet body 17b by screwing the bolt 38b into the nut 38a via the lower bracket 39 having a hat-shaped cross section. The lower bracket 39 has a protruding piece 39a whose front surface abuts on the rear surface of the cover portion 17c, and a nut 39b is welded to the rear surface of this protruding piece 39a. A wrap outer anchor 41 is attached to one end of the webbing 32 (FIGS. 2 and 3). A bolt 39c is attached to the nut 39b via a lap outer anchor 41.
The lap outer anchor 41 is attached to the lower front portion of the lower cabinet 17 by screwing.

An upper reinforcing plate 42 is welded to an upper portion of the rear surface of the front wall 17d of the cabinet body 17b so as to be located above the lower reinforcing plate 38, and a nut 42a is welded to the reinforcing plate 42 (see FIG. 3). ). By screwing the bolt 42b into the nut 42a via the retractor 31, the retractor 31 is attached to the front wall 1 of the cabinet body 17b.
It is fixed to the upper part of 7d, that is, the retractor 31 is housed inside the lower cabinet 17. Again cabinet 1

The nut 43a is welded to the (FIGS. 1 to 3). The shoulder anchor 44 is attached to the upper bracket 43 by screwing a bolt 43b into the nut 43a via a shoulder anchor 44 that slidably holds the webbing 32.

The cover portion 17 of the lower cabinet 17
Insertion hole 17e is provided at the upper end of the c so as to face the shoulder anchor 44.
(FIG. 3) is formed, and the other end of the webbing 32 is connected to the retractor 3 via the shoulder anchor 44 and the insertion hole 17e.
It is configured to be wound up into a roll 1 (FIGS. 1 to 3). The webbing 32 is provided in a substantially vertical direction from the step 13 toward the front surface of the lower cabinet 17 to one side of the guide seat 19, that is, rightward in a non-use state (FIGS. 1 to 3). Further, the base end of the inner belt 34 extends from the step 13 toward the front surface of the cabinet 16 and wraps on the inner surface of the recess 17a on the other side of the guide seat 19, that is, on the left side.
Attached (FIGS. 1, 4 and 5).

A method of using the bus having the guide seat thus configured will be described. When using the guide seat 19, first, the handle 29 is operated to release the lock device (not shown), and the seat cushion 19a is rotated in the direction indicated by the solid arrow in FIG. At this time, the second link 22 rotates in the direction of the one-dot chain line arrow around the second fixed side pin 22a, and the first link 21 rotates in the direction of the broken line arrow around the first fixed side pin 21a. When the seats 21 and 22 reach the positions shown in FIG. 5, the seat cushion 19a is held in the horizontal position. That is, the links 21 and 22 that have reached the position shown in FIG. 5 interfere with each other to prevent the seat cushion 19a from rotating further downward from the horizontal position.
Is kept in a horizontal position.

Next, after the arm 27 folded on the upper surface of the seat cushion 19a is rotated around the third pin 23 together with the seat back 19b in the direction shown by the solid line arrow in FIG. 5, the seat back 19b is lifted up. When the seat back 19b reaches the position indicated by the alternate long and two short dashes line by rotating around the 4-pin 24 in the direction of the broken line arrow, the guide seat 19 is deployed in a usable state. Further, a bus guide or a passenger (not shown) sits in the guide seat 19, pulls the tongue plate 36 loosely fitted to the webbing 32 of the three-point seat belt 20 toward the chest, and the inner belt 3 stored in the recess 17a.
Pull the buckle 33 of No. 4 to the waist and pull out the tongue plate 3
6 is locked to the buckle 33. As a result, the three-point seat belt 20 surely restrains the waist and chest of the bus guide or the passenger, so that the restraining performance of the bus guide or the passenger is improved.

When the guide seat 19 is returned from the use state to the non-use state, the inner belt 34 and the guide seat 19 are placed in the recess 1 of the lower cabinet 17 in the reverse order of the above procedure.
7a, and the bottom surface of the seat cushion 19a is substantially flush with the front surface of the lower cabinet 17, so that the guide seat 19 does not interfere with passengers and passengers not shown in the drawing, and the appearance of the front surface of the cabinet 16 is improved. There is no loss.
