Description

The present invention relates to a seating system installed in a vehicle such as an aircraft.

Conventionally, in a seat system installed in an aircraft or the like, a plurality of rows of seats have been installed on both sides of the aisle. For example, in the case of a large aircraft, three rows of seats were installed on the left side of the aircraft, four rows of seats were installed in the center of the aircraft, and three rows of seats were installed on the right side of the aircraft. And there was an aisle between each seat row. In addition, many seat rows were installed along the aisle.

However, the distance between the rows of seats along the aisle was only large enough to accommodate the passengers' feet. For this reason, for example, among the passengers sitting in the three rows of seats on the left side of the aircraft, in order for the passengers in the window seat and the passengers in the center seat to enter the aisle, the passengers in the aisle are asked to withdraw. Or I had to get them to stand in the aisle. For this reason, when the passengers near the aisle are sleeping, in order for the passengers on the window side to enter the aisle, the passengers near the aisle must be called out to wake up.

The present invention has been made in view of the above problems, and the first means of the present invention is a seating system installed in a vehicle having an aisle in a direction orthogonal to the longitudinal direction of the aisle. It has multiple seats, each seat has a lateral movement function that moves in a direction orthogonal to the aisle, and the aisle-side seat of each seat has a vertical movement function that moves along the aisle. It has a structure of being. By adopting such a configuration, the aisle-side seats move laterally toward the aisle and vertically along the aisle. As a result, the seat on the back side of the aisle can be laterally moved to a position facing the aisle. Passengers in the back seats can enter the aisle without calling out to the aisle passengers.

Further, in the second means, each seat is provided with a step for placing the passenger's feet. Therefore, when the seat moves, the passenger's feet also move together with the seat, so that the seat can be moved without the passenger noticing.

Further, in the third means, each seat is provided with a seat movement switch, and the seat is moved according to the operation of the seat movement switch by the passenger. Therefore, the seats can be moved according to the wishes of the passengers.

Further, in the fourth means, the lateral movement function has a configuration in which it has a lateral movement regulating function that regulates lateral movement when another seat is present on the aisle adjacent to the seat. Therefore, collision between adjacent seats is prevented.

Further, in the fifth means, at least three seats are provided in a direction orthogonal to the longitudinal direction of the aisle, and at least two seats near the aisle have a vertical movement function. For this reason, the seat at the innermost part (near the window) when viewed from the aisle can also be moved to a position facing the aisle, further improving convenience.

Further, in the sixth means, a toilet is installed at a predetermined position in the aisle, and the vertical movement function has a usage status detection function for detecting the usage status of the toilet, which is opposite to the position of the unused toilet. The structure is such that the seat is moved vertically in the direction. Therefore, the seat moves in an appropriate direction according to the usage status of the toilet, which facilitates the use of the toilet.

According to the present invention, since the seat itself moves, the seat of the passenger on the back side of the aisle can be moved to a position facing the aisle. This allows passengers in the back seats to enter the aisle without waking up passengers in the aisle seats.

It is a top view of the seat system which concerns on one Embodiment of this invention, and is the figure which shows the seat arrangement in the initial state. From the seat arrangement disclosed in FIG. 1, it is a figure which shows the seat arrangement after the two seats at the aisle and the center move laterally toward the aisle. From the seat arrangement disclosed in FIG. 2, it is a figure which shows the seat arrangement after one seat at the aisle vertically moves backward along the aisle. It is a figure which shows the state which the passenger of the central seat went out to the aisle in the seat arrangement disclosed in FIG. In the seat arrangement disclosed in FIG. 4, it is a figure which shows the state which the passenger of the central seat has returned to the seat. From the seat arrangement disclosed in FIG. 5, it is a figure which shows the seat arrangement after one seat by the aisle moves forward longitudinally along the aisle. From the seat arrangement disclosed in FIG. 6, it is a figure which shows the seat arrangement (the same as the initial state) after the two seats at the aisle and the center move laterally toward a window side. It is a figure which shows the seat arrangement after the two seats at the aisle and the center move vertically rearward along the aisle from the seat arrangement in the initial state, and the seat on the window side moves laterally to the position facing the aisle.

An embodiment of the seating system of the present invention will be described below with reference to the drawings. In the description, common parts are designated by the same reference numerals, and duplicate description will be omitted as appropriate.

The seat system of the present embodiment is installed in a vehicle having an aisle, has a plurality of seats S1 to S3 in a direction orthogonal to the longitudinal direction of the aisle, and each seat S1 to S3 has an aisle. The seats S1 and S2 on the aisle side of the seats S1 to S3 are provided with a lateral movement function of moving in a direction orthogonal to the aisle. Examples of vehicles include aircraft, buses, trains, ships, automobiles, etc., but all vehicles in which a plurality of seats are installed in a direction orthogonal to the longitudinal direction of the aisle are targeted.

FIG. 1 is a plan view showing the seat arrangement in the initial state. In the example of FIG. 1, three seats S1 to S3 are arranged in a direction orthogonal to the longitudinal direction of the aisle. In FIG. 1, for convenience of explanation, a state in which passengers P1 to P3 are seated in three rows of seats S1 to S3 sandwiched between front seats and rear seats is illustrated. In the initial seat arrangement, in order for the passenger P2 of the central seat S2 to enter the aisle, it is necessary to have the passenger P1 of the seat S1 near the aisle make a space. However, in the seat system of the present embodiment, as described below, since the seat itself moves, it is not necessary for the passenger P1 of the seat S1 near the aisle to make a space. This will be described in detail below.

Each seat S1 to S3 is provided with a seat movement switch. The seat movement switch is for moving the seats S1 to S3 according to the wishes of the passengers P1 to P3. Further, seat rails 3 are provided on the aisle and the floor surface. Seats S1 to S3 are engaged with the seat rails 3, so that the seats S1 to S3 can move along the seat rails 3. For example, when the passenger P2 of the central seat S2 in FIG. 1 operates the seat movement switch, as shown in FIG. 2, the seat of the aisle S1 and the central seat S2 move toward the aisle along the seat rail 3. Move sideways. At this time, each of the seats S1 and S2 includes a step 5 for placing the feet of the passengers P1 and P2, and when the seats S1 and S2 move, the passengers P1 and P2 remain on the steps 5. Seats S1 and S2 move at. However, the lateral movement function also has a lateral movement regulation function. This is a function of restricting the movement of seats S1 and S2 when there are other seats in the adjacent aisle. Therefore, even when the passenger P2 of the central seat S2 operates the seat movement switch, the seats S1 and S2 do not move laterally if there are other seats in the adjacent aisle. Seats S1 and S2 move laterally after the other seats no longer exist on the adjacent aisle.

After that, as shown in FIG. 3, the seat S1 near the aisle moves vertically toward the rear. As a result, the passenger P2 in the central seat S2 after the movement can freely go out to the aisle without having the passenger P1 in the seat S1 at the aisle leave a space. Even in the seat arrangement shown in FIG. 2, since the passenger P2 of the central seat S2 can go out to the aisle, it is not essential that the seat S1 at the aisle moves vertically backward.

In the examples of FIGS. 1 to 4, the seat S1 near the aisle moved vertically toward the rear of the aisle. However, the seating system of the present invention is not limited to this. For example, when toilets are installed in front of and behind the aisle when viewed from seats S1 to S3, it is desirable to control the direction of vertical movement according to the distance to the toilet and the usage status of the toilet. If the distance from the seats S1 to S3 to the toilet in front of the aisle is shorter than the distance to the toilet in the rear, the seat S1 at the aisle moves rearward along the aisle. As a result, the passenger P2 in the central seat S2 can go to the toilet in front of the aisle.

In addition, the vertical movement function of the seat has a toilet usage status detection function. Therefore, for example, when the toilet in front of the aisle is in use and the toilet in the rear is vacant, the seat S1 near the aisle moves forward along the aisle. This allows passengers in central seat S2 to head to the toilet behind the aisle.

Next, the process of returning the seat arrangement to the initial state will be described with reference to FIGS. 5 to 7. FIG. 5 shows a state in which the passenger P2 in the central seat S2 has returned to the seat S2. From this state, as shown in FIG. 6, the seat S1 near the aisle vertically moves forward along the aisle. After that, as shown in FIG. 7, the aisle seat S1 and the central seat S2 laterally move to the window side. As a result, the seat arrangement returns to the initial state.

FIG. 8 is a diagram illustrating a case where the passenger P3 of the seat S3 near the window goes out to the aisle. As shown in this figure, the aisle seat S1 and the central seat S2 (collectively referred to as "aisle-side seats") move laterally and then vertically move backward along the aisle. As a result, the seat S3 near the window can be moved to a position facing the aisle. Passenger P3 in seat S3 by the window can easily enter the aisle. Further, as a secondary effect, even if an elderly person with a physical disability is sitting on the seat S3 near the window, the seat S3 can easily go out to the aisle because the seat S3 moves laterally.
