Description

[Detailed Description of the Invention] Industrial Field of Application This invention relates to improvements in auxiliary seats used in buses.

BACKGROUND TECHNOLOGY Normally, the auxiliary seats installed in buses are made to be foldable, but the height of the seat in use is fixed in relation to the aisle, so the aisle is located on the general surface of the floor. If it is lower than , there will be a step between it and the two-seater seats when in use,
It was difficult to use it to lie down comfortably in the audience seats or take a nap.

Further, Japanese Utility Model Publication No. 49-11787 discloses a foldable driver's seat.

In this seat, the fastening metal fittings that are slidably guided in the vertical direction by the partition rod have a 2-split structure.
In addition, the number of parts is large and manufacturing is complicated, and the surface of the partition bar, the so-called guide surface, is damaged by the sliding of the fastening fittings, so the appearance of the partition bar deteriorates as it is used.

Furthermore, Japanese Patent Publication No. 48-14738 describes a grooved guide rail with an inward flange and its guide.
A movable seat for a vehicle is disclosed that utilizes an outwardly flanged slider that is reciprocally slidably fitted to a rail.

In this movable seat, the slider is fixed to the guide rail by crimping the outward flanges of the slider to the inward flanges of the guide rail, so those flanges are not bent by forceful crimping. There was a risk that the seat would not be able to be fixed in an appropriate position.

Furthermore, Japanese Utility Model Application Publication No. 59-165234 discloses a seat device for a tractor.

In this seat device, a turntable is rotatably supported on a seat base by a spindle,
A nut with a handle lever connected to the threaded portion of the spindle was used to fix the turntable to the seat base. The nut was tightened and loosened several times, making setting up the seat cumbersome and requiring a large space to turn the handle.

Purpose and problem of this invention The purpose and problem of this invention is to make the seat height adjustable according to the usage conditions, and to make it possible to adjust the seat height with a simple operation, especially in narrow spaces, and to make it possible to adjust the seat height to a two-seater passenger seat. It allows you to lie down comfortably, makes resting and napping easier, reduces the number of parts and makes manufacturing and assembly easier, and
The objective is to provide an auxiliary seat used in a bus that is of a foldable type that ensures good appearance when used.

Description of Specific Examples Specific examples of the sheet of this invention will be described below with reference to the drawings.

1 to 4 show a specific example 10 of an auxiliary seat for use in a bus according to the present invention, which is made foldable and applied to a bus.

The auxiliary seat 10 has a pair of guide rails 1
4, 14, a pair of sliders 15, 15, and
A pair of clamp means 16, 16 are provided and fixedly arranged on the seat frame 31 and leg 32 on the aisle 40 side of the two-seater passenger seats 30, 30 arranged in the vehicle interior.

The pair of guide rails 14, 14 are connected to the seat frame 31 and leg 3 of the two-seat passenger seats 30, 30 on the side of the aisle 40 inside the vehicle.
2 so that it can be guided in the vertical direction.

The guide rails 14, 14 are cut to a predetermined length from a channel material with an inward lip, as shown in FIG.
4 was punched out using a press to create a cross-sectional shape of a channel with an inward lip.

The pair of sliders 15, 15 are fixed to corresponding arms 17, 17 that support the auxiliary seat frame 13, and are fitted so as to be reciprocally slidable in correspondence with the guide rails 14, 14.

The sliders 15, 15 are connected to the guide rails 14, 14 as shown in FIGS.
The channel material with the outward lip is cut to a predetermined length and the arm 1 is attached to the web.
The arms 17, 17 were welded at their bases, and the arms 17, 17 were more firmly connected by welded auxiliary members 18, 18 and a connecting member 19, and were manufactured in a cross-sectional shape with an outward lip.

The pair of clamping means 16, 16 are attached to the slider 15, 1 on the guide rail 14, 14.
5 was manufactured in a structure that allows for corresponding fixation.

The clamping means 16, 16 are welded to the webs of the sliders 15, 15 and are attached to threaded rods 20, 20 extending through elongated holes in the guide rails 14, 14 and to the webs of the guide rails 14, 14. A clamping block 21, 21 having a pressed cam surface (not shown) and threadedly connected to the threaded rod 20, 20; a handle 22 integrally formed on the clamping block 21, 21; 22.

Further, in this auxiliary seat 10, 11 is a foldable seat cushion, 12 is a foldable seat back, and 23 is a bracket.

Next, to explain the use of the auxiliary seat 10, the auxiliary seat 10 has its handles 22, 22.
and its clamping block 21,2
1 and slide the sliders 15, 15 downward along the guide rails 14, 14,
Move the seat cushion 12 to the position shown by the solid line in FIG.
If the clamping blocks 21, 21 are tightened by operating the handles 22, 22, the clamping blocks 21, 21 are set in the normal use position;
and slide the sliders 15, 15 upward along the guide rails 14, 14,
Move the seat cushion 11 to the position shown by the chain line in FIG.
operate the clamping block 2 again.
If seats 1 and 21 are tightened, the seat height will match that of the passenger seat 30, allowing for a relaxing nap.

As such, the clamping block 2
1 and 21 are equipped with cam surfaces, the seat height can be adjusted in a narrow space with a simple operation. In addition, the guide rail 14,
14 and the outward lips of the sliders 15, 15 are avoided, and the guide surfaces of the guide rails 14, 14 and the slider 1, which are damaged by the sliding of the sliders 15, 15, are avoided.
The sliding surfaces of 5 and 15 are the guide rails 14 and 1.
In use, its guide rails 14, 14 and slider 15,
15 good looks were ensured.

Convenience and benefits of the invention As can be understood from the above, the auxiliary seats used in the bus of this invention have guide rails with elongated holes in the web and are arranged in the aisle of the two-seat passenger seats. The slider has a channel cross-sectional shape with an inward lip that is fixed to the side leg and can be guided in the vertical direction, and the slider has an outward lip that is secured to the inward lip of the guide rail. the slider is reciprocatingly slidably fitted to the guide rail and configured with an outwardly directed lip for supporting the passenger seat frame; further clamping means is fixedly connected to the web of the slider and configured to support the passenger seat frame; - A threaded rod that passes through a long hole in the rail, a clamping block that has a cam surface that is pressed against the web of the guide rail and is screwed to the threaded rod, and is integrally attached to the clamping block. It consists of a handle that is connected to the slider, and the slider can be fixed to the guide rail at an appropriate position, so the seat height can be adjusted according to the usage condition by simple operation using the clamping means in a narrow space. That is, when the seat height is adjusted to the aisle, it can be used as a stool, and when the seat height is adjusted to that of a two-seater passenger seat, it can be used to lie comfortably on the passenger seat. This makes it much easier to take a break or take a nap.Furthermore, deformation of the guide rail and the lip of the slider can be avoided and the slider can be firmly fixed to the guide rail. The seat is firmly and reliably supported in the appropriate position, and the number of parts is reduced, making manufacturing and assembly easier. - Located inside the rail, in use, the appearance of its guide rail and slider is ensured, which is very useful and practical for tour buses.
