Problems solved by technology

[0008] However, the structure in Patent Document 1 is a system that detects changes in the current value of the motor that drives the leg rest, so unless a phenomenon such as collision or entrapment of the leg rest occurs, the operation cannot be stopped.
Therefore, in the structure of Patent Document 1, it is impossible to prevent the collision between the leg rests, or the luggage or the user's legs, etc. are caught in the leg rests.

[0068] figure 1 is a perspective view showing the entire seat device 100 according to one embodiment of the present invention. figure 2 is a schematic block diagram showing the structure of the seat device 100 . In addition, each figure shows three axial directions perpendicular to each other, X-axis, Y-axis, and Z-axis, and the X-axis, Y-axis, and Z-axis correspond to the front-rear direction, the left-right direction, and the height direction, respectively.

[0069] [Overall structure of the seat unit]

[0070] The seat device 100 includes: a seat main body 10; a base F fixed to a floor surface; an inversion portion 20 supporting the seat main body 10 in such a manner that the seat main body 10 is reversible with respect to the base F; control unit 30. The seat device 100 constitutes, for example, a part or all of a plurality of seats arranged in a row in a passenger compartment of a railway vehicle such as a Shinkansen or an express train.

[0136] Figure 9 is a schematic configuration diagram of a seat system 120 according to a second embodiment of the present invention.

[0137] Hereinafter, structures different from those of the first embodiment will be mainly described, the same structures as those of the first embodiment will be given the same reference numerals, and descriptions thereof will be omitted or simplified.

[0138] The seat system 120 of the present embodiment is constituted such that the structure of the control unit 40 of each seat (the own seat 100, the front seat 101, and the rear seat 102) is different from that of the first embodiment, and the control unit 40 detects each The posture of the seat can not only restrict the tilting motion of the leg rest 14 but also restrict the tilting motion of the backrest 12 . Hereinafter, although the description is centered on the control unit 40 of the own seat 100 , the same applies to the control units 40 of the front seat 101 and the rear seat 102 ....

[0156] Figure 11 is a schematic configuration diagram of a seat system 130 according to a third embodiment of the present invention. Figure 12 It is a schematic block diagram showing the configuration of a seat device 200 constituting each seat of the seat system 130 .

[0157] Hereinafter, structures different from those of the first embodiment will be mainly described, the same structures as those of the first embodiment will be given the same reference numerals, and descriptions thereof will be omitted or simplified.

[0158] The seat device 200 constituting the own seat 100, the front seat 101 and the rear seat 102 has the same structure as the seat device 100 of the first embodiment, but in this embodiment, as Figure 12 As shown, the seat apparatus 200 has a sensor 24 for detecting that the positioning of the seat body 10 relative to the base F by the locking mechanism (lock pin 21 ) is released. The output of the sensor 24 is output to a control unit 50 described la...

Abstract

A seat device according to one aspect of the present invention is provided with a seat body and a control unit. The seat body has a leg rest, a first operation part for operating the leg rest, and a first driving part that tilts the leg rest forward and backward on the basis of the input operation of the first operation part. The control unit has a first detection part and a control part. The first detection part detects the direction of a front seat positioned in the front row of the seat body. When the front seat faces at least the seat body, the control part invalidates, on the basis of theoutput from the first detection part, the command, issued from the first operation part, for operating the leg rest to tilt forward relative to the first driving part.

Description

technical field [0001] The invention relates to a seating arrangement with a leg rest and a seating system. Background technique [0002] Conventionally, seat devices equipped on railway vehicles and the like have leg rests for providing a comfortable ride. A seat device having such a leg rest is configured so that the leg rest can be tilted forward and backward by a motor between the leg rest position and the stowed position by an input operation by a user (seat occupant). [0003] On the other hand, seat devices equipped on railway vehicles and the like are each rotatably provided on a base provided on a floor surface. Usually, each seat device is used facing the traveling direction, but it can be used while facing the direction opposite to the traveling direction by turning it in the opposite direction by an operation by a user such as a passenger. In this way, when the respective leg rests are operated in a state where the fronts of the seat device face each other in t...
