[0043] The seat heater 85 is disposed between the pad material 80a and the cover material 80b, and can warm an occupant who touches the cushion body 80. The power receiving unit 86 is disposed between the padding material 80a and the covering material 80b, and when attached to the vehicle seat 1 or the vehicle door 101, receives electricity through the vehicle seat 1 (power supply unit 75) or the vehicle door 101 (power supply unit 160). Inside the cushion body 80, a harness that electrically connects the seat heater 85 and the power receiving portion 86 is disposed.

[0044] In the above configuration, the cushion body 80 is attached to the inner surface of the vehicle door 101 so as to cover the handle portion 112 of the armrest 110, as shown in FIG. Therefore, it is possible to prevent the occupant from directly hitting the armrest 110 when leaning against the vehicle door 101. This improves the seating feeling of the occupant.

[0045] In the above configuration, the seat cushion 10 has a holding member 16 that holds the cushion body 80, as shown in FIG. Therefore, the cushion body 80 can be stably attached to the outer surface of the seat cushion 10 by utilizing the holding member 16.

[0046] In the above configuration, as shown in FIG. 4, when the detection sensor 150 detects that the cushion body 80 is attached to the vehicle door 101, the control device 70 controls the vehicle door 101 (opening / closing lock device) so that it cannot be opened or closed. This makes it possible to prevent the vehicle door 101 from being opened or closed unintentionally when an occupant is seated and leaning against the vehicle door 101 (cushion body 80). At this time, when the control device 70 receives the detection results from the detection sensor 150, the pressure detection sensor 60, and the pressure detection sensor 84, it is preferable to control the vehicle door 101 so that it cannot be opened or closed. This makes it possible to control the vehicle door 101 so as to be unable to open or close when the occupant is leaning against the vehicle door 101 (cushion body 80) and seated on the seat cushion 10. That is, the pressure detection sensor 60 inside the seat cushion 10 can detect that the occupant is sitting sideways on the seat cushion 10. In addition, the control device 70 may appropriately control the opening and closing locking of the vehicle door 101 by using the detection sensor 17 of the vehicle seat 1, the pressure detection sensor 60, the pressure detection sensor 84 of the cushion body 80, and the detection sensor 150 of the vehicle door 101.

[0047] In the above configuration, when it is detected that the cushion body 80 is attached to the vehicle door 101 as shown in Figures 3 and 4, the control device 70 controls the operation of the cushion changing device 50 so as to lower the protruding portion of the cushion side portion 12. At this time, the control device 70 may control the operation of the reclining device 40 so as to tilt the seat back 20 slightly forward or slightly backward. This can improve the seating comfort of the occupant. For example, the seat cushion 10 can be changed to a flat seating surface.

[0048] <Vehicle interior decoration method> Next, an example of the processing of the vehicle interior program (vehicle interior method) executed by the vehicle interior system S1 (control device 70) will be described with reference to FIG. The above program is executed by a CPU (processor) of the control device 70 having a storage unit. The execution of the above program is triggered, for example, by an occupant sitting in the vehicle seat 1. Alternatively, the execution of the program is triggered by a user operating an operating device (not shown).

[0049] The process flow shown in FIG. 5 starts with step 1 (S1) in which the control device 70 detects that the cushion body 80 is attached to the vehicle seat 1 when the detection sensor 17 of the vehicle seat 1 is turned ON. At this time, the cushion body 80 is in a state of being integrally attached to the vehicle seat 1 as shown in FIG.

[0050] Then, in step 2, when the detection sensor 17 of the vehicle seat 1 is turned OFF, the control device 70 detects that the cushion body 80 has been removed from the vehicle seat 1. This makes it clear that the occupant has removed the cushion body 80.

[0051] Then, in step 3, when the detection sensor 150 of the vehicle door 101 is turned ON, the control device 70 detects that the cushion body 80 has been attached to the vehicle door 101. At this time, the cushion body 80 is attached so as to cover the arm rest 110 as shown in FIG.

[0052] Then, in step 4, when the pressure detection sensor 84 of the cushion body 80 is turned ON, the control device 70 detects that the occupant is leaning against the cushion body 80. At this time, the control device 70 receives the detection signal (ON) of the pressure detection sensor 84 and the detection signal (ON) of the pressure detection sensor 60 of the vehicle seat 1, and detects the seating state of the occupant (leaning to the side). By using a plurality of pressure detection sensors in this manner, the control device 70 can detect the state of the occupant with higher accuracy.

[0053] Then, in step 5, the control device 70 controls the locking of the vehicle door 101 for opening and closing. This makes it possible to control the vehicle door 101 so that it does not open or close when an occupant is leaning against the vehicle door 101 (cushion body 80).

[0054] Then, in step 6, the control device 70 determines whether the pressure detection sensor 84 has been turned OFF. If the pressure detection sensor 84 is OFF (step 6: Yes), the process proceeds to step 7, where the control device 70 unlocks the vehicle door. On the other hand, if the pressure detection sensor 84 is not turned OFF (step 6: No), the process returns to step 5. After going through steps 1 to 6 above, the process of FIG. 5 is completed.
