Problems solved by technology

[0008] However, in the structure of reference document 1, since the current change of the motor driving the leg drag is detected, if the leg drag is not collided with each other, is After the occurrence of clamping, etc., it will not stop the action
Therefore, in the structure of Reference Document 1, it is impossible to prevent the leg drags from colliding with each other or the leg drags from catching luggage, the user's feet, etc.

Abstract

To prevent leg rests from bumping against each other, for example, and to allow a leg rest of a seat to move even when a power supply failure or the like occurs. The seat device according to a mode of the present invention is equipped with a seat body, a control unit, and a setting means. The seat body has a leg rest. The control unit has a controller. The controller determines whether the seat body is in a first state in which the seat body does not face a seat in front or a seat in back thereof or a second state in which the seat body faces either the seat in front or seat in back thereof. The controller enables an inclination operation command for the leg rest to incline forward when the controller has determined that the seat body is in the first state, and invalidates the inclination operation command when the controller has determined that the seat body is in the second state. The setting means fixes the first state for the determination result from the controller.

Description

technical field [0001] The present invention relates to a seating device with a leg drag and a seating system. Background technique [0002] Currently, among seat devices equipped on railway vehicles and the like, there are seat devices equipped with leg drags for providing comfortable seating. A seat device including such a leg drag is configured to be able to tilt the leg drag in the front-rear direction between the footrest position and the storage position by a motor according to an input operation by a user (occupant). [0003] On the other hand, seat devices equipped on railway vehicles and the like are each rotatably installed on a floor-mounted base. Typically, each seat device can be used facing the forward direction, but it can also be used in a state of facing in a direction opposite to the forward direction by reversing the operation by a user such as a passenger. In this way, if the respective leg drags are operated in a state where the fronts of the seat devi...
