Description

Detailed Description of the Invention [Industrial Field of Application] The present invention is intended for use in various vehicles that transport passengers, such as aircraft, ships, trains, buses, etc. The present invention relates to a method for changing a passenger cabin space, for changing the passenger living space itself by widening the pitch between seats, and a vehicle seat used in the changing method.

[Prior Art] In various conventional vehicles for transporting passengers, a large number of vehicle seats (hereinafter simply referred to as seats) are installed at intervals on the floor of the cabin, and the cabin is Mostly used as passenger living space,
It may also be used for other purposes (for example, cargo loading space).

- Taking an aircraft as an example, a conventional aircraft seat is attached to the floor of a passenger cabin in the following structure.

As shown in FIGS. 10 to 15, on the floor surface 6 of the cabin of the aircraft 1, there is a channel-shaped floor rail 7 having a plurality of insertion holes 8 and a retaining edge 9 alternately provided at the upper end opening. Multiple lines are laid in parallel depending on the seat rows. On the other hand, a mounting bracket 53 is attached to the lower end of the front leg 52 of the seat 51, and a mounting bracket 53 is provided with a mounting bracket 53 that slides freely into the floor rail 7 from the insertion hole 8 and is latched to the retaining edge 9. A number of retaining studs 54 are attached. Further, a mounting bracket 56 is attached to the lower end of the rear leg 55, and two retaining studs 57 are similarly attached to the mounting bracket 56.
A fixing stud 58 is attached that fits into and locks into the insertion hole 8, and the fixing stud 58 can be moved up and down by manually rotating the operating member 59 (using a screwdriver or the like). It is configured.

To attach the seat 51 to the floor rail 7, first raise the fixing studs 58 of the rear legs 55 by manually rotating the actuating member 59 as shown in FIG. and each retaining stud 54 of the rear leg 55
．． 57 into the floor rail 7 through the insertion hole 8. Next, by manually moving the seat 51 slightly in the front and back direction, each of the retaining studs 54 and 57 slide within the floor rail 7, as shown in FIG. 13, and the seat 51 is moved to the planned mounting position. let Then, with each of the locking studs 54 and 57 positioned between adjacent fitting holes 8 and hooked to the locking edge 9, the actuating member 59 is manually rotated again to fit the fixing studs 58 into the fitting holes 8. All you have to do is fit it in and lock it.

[Problems to be Solved by the Invention] However, as shown in FIG. When changing the passenger accommodation space itself, the conventional seat 51 described above has a problem in that it is extremely troublesome to remove it.

i.e. when there are few passengers on the aircraft or on charter flights! When there are no passengers at all, as was the case in Japan, in order to maximize the efficiency of aircraft transportation, it is possible to create a cargo loading space in the cabin and load not only passengers but also cargo, or to load only cargo. Sometimes, it is common practice to directly load cargo onto the seat 51.

Furthermore, when there are few passengers, the pitch between seats may be widened in order to improve comfort for the passengers and improve serviceability.

However, to change the cabin space as described above, seat 51
The following methods are being explored because the presence of the person and the presence of his/her support become a hindrance.

(1) As shown in Fig. 15, for example, seat 5 at the rear of the audience seats.
1 from the floor rail 7 and take it out of the aircraft, and create a cargo loading space for cargo F in the empty space.

However, in order to remove this seat 51, it is necessary to manually raise the fixing stud 58 of each seat 51 and remove it from the insertion hole 8, and to carry each seat 51 out of the aircraft individually, which requires a lot of work. It took a lot of effort and time. Further, there were also problems such as not being able to carry passengers during the flight when returning to install the removed seats 51, and having to carry each removed seat 51 back into the aircraft and attach it to the floor rail 7.

(2) Although not shown, a method of manually moving some or all of the seats 51 along the floor rail 7 and gathering them in one or several locations to create a cargo loading space in the empty space.

However, in order to move this seat 51, after manually removing the fixing stud 58 of each seat 51 from the insertion hole 8, each seat 51 is manually moved largely, and then the fixing stud 58 is manually lowered again. Since the troublesome work of latching it into the fitting hole 8 is required, it takes more labor and time than the method (1) above.

(3) Although not shown, when loading cargo directly onto the seats 51, manually fold the backrests of each seat 51 forward,
It was necessary to carry out work to allow cargo to be loaded on the back (top surface) of the back support, which again took a lot of effort and time.

(Method for changing cabin space No. 1) A method of changing the cabin space from the original passenger living space to a usage space (here, cargo loading space) using the seats 11 configured as described above, together with the effects and effects. explain.

(1) First, when only passengers board the full-capacity cabins 2a to 2e of the aircraft 1, the seats 11 of this embodiment are spaced apart from each other as shown in FIG. 14, just like the conventional seats. It is arranged at a predetermined initial position, and a passenger living space is formed in the full-capacity rooms 2a to 2e. At this time, each seat 11
The spring body 25 of the fixing and unfixing device A drives the fixing stud 24 downward so that it fits into and latches into the insertion hole 8 of the floor rail 7, and also drives the fixing stud 24 downwardly so that it fits into and latches into the insertion hole 8 of the floor rail 7.
22 is located between the insertion holes 8 and hooked to the retaining edge 9, so that each seat 11 is fixed to the floor rail 7.

(2) Next, when trying to load not only passengers but also cargo in the cabins 2a to 2e, for example, as shown in Figures 5 and 6, passengers are loaded in the first cabin 2a to third cabin 2c, and When attempting to load cargo F into the fifth cabin 2e, proceed as follows.

As shown in FIG. 3, by operating the control device, the electromagnetic solenoid and id 26 of the fixing and unfixing device A for the seats 11 of the fourth passenger cabin 2d and the fifth passenger cabin 2e are operated, and the fixing stud 2 and the fixing stud 2 are operated. 1 upward and remove it from the insertion hole 8 of the floor rail 7.

Subsequently, the electric motor 3.4 as a drive source in the seat moving device B, which is automatically controlled by the control device, is rotated in the forward direction to drive the plurality of hooks 33 to sequentially hook them into the insertion holes 8. As a result, the seat 11 is moved forward along the floor rail 7 from the initial position, and
They close the distance between each other and stop at the fourth cabin 2d, which serves as the gathering location.

Subsequently, as shown in FIG.
The seat 11 is re-fixed by driving the fixing stud 24 downward by the elastic force and fitting it into the insertion hole 8 of the floor rail 7. As a result of the above, a cargo loading space as an example of a usable space is formed in the fifth cabin 2e, and the cargo F can be loaded in this space.

At this time, by tilting the backrest 49 of the seat 11 forward by a backrest tilting device automatically controlled by the control device, the backrest 49 of the seat 11 is turned to the back (upper surface) to form a cargo loading space. I can do it.

Note that the gathering position of the seats 11 can be set at any one place or three or more places in the passenger rooms 2a to 2e, and the gathering position can also be set to be arbitrarily changeable. Also,
Even when loading only the cargo F into the cabins 2a to 2e, the seats 11 may be moved to one or more arbitrary gathering positions in the same manner as described above.

(2) Next, if there are few passengers and you want to change the passenger living space by widening the pitch between seats, for example, as shown in FIG. In order to widen the pitch between the seats in the passenger cabins 2a to 2d, the following steps will be taken.

The method of unfixing the seat 11 using the fixing and unfixing device A is the same as step (2) of the modification method 1 above.

Next, the seat moving device B automatically controlled by the control device moves the seats 11 of the fifth cabin 2e from the initial position to the rear along the floor rail 7, closes the distance between them, and sets them as a gathering position. It will be stopped at the rear of the fifth cabin 2e. At the same time, the seats 11 of the first cabin 2a to the fourth cabin 2d are moved backward from the initial position along the floor rail 7, and the pitches between the seats are widened and the seats 11 are stopped at the moving position.

The subsequent method of fixing the seat 11 using the fixing and unfixing device A is the same as step (2) of the first modification method.

In this case, the gathering position can be set to one arbitrary location or three or more locations, or can be set to be arbitrarily changeable.

(3) If you want to return the passenger living space to its original state, do the following.

The method of unfixing the seat 11 using the fixing and unfixing device A is the same as step (3) of the first modification method.

Subsequently, the seat moving device B automatically controlled by the control device moves the seats 11 of the first cabin 2a to the fourth cabin 2d from the moving position forward along the floor rail 7, and moves the seats 11 between the seats to each other. Return the pitch to the original position and stop at the initial position.

At the same time, the seats 11 of the fifth passenger cabin 2e are moved forward along the floor rail 7 from the gathering position, and are stopped at the initial position at a distance from each other.

The subsequent method of fixing the seat 11 using the fixing and unfixing device A is the same as step (3) of the modification method 1 above.
