Summary of the Invention
Problems to be Solved by the Invention
[0004] For the switch described in Patent Document 1 and the like, a separate switch for switching the function of the switch is required. Therefore, the user needs to operate the switch for executing the function after operating the function switching switch. The present disclosure discloses an example of a reclining seat including a switch in view of this point.
Means for Solving the Problems
[0005] A reclining seat capable of displacing the posture of a seat body (2) including a seat back (4) and a seat cushion (5) between a reclining posture for reclining and a seating posture for sitting preferably includes at least one of the following constituent requirements.
[0006] That is, the said constituent element is a posture detection unit (10) for detecting the posture of the sheet body (2), a user detection unit (11) for detecting whether or not a user exists on the sheet body (2), an operation panel (7) provided on the sheet body (2) and operated by the user, a switch unit (12) provided at a part other than the operation panel (7), and a function determination unit (9) for determining the function to be executed when the switch unit (12) is operated, wherein the function determination unit (9) determines the said function by using at least one detection signal out of the detection signal of the posture detection unit (10) and the detection signal of the user detection unit (11).
[0007] According to the inventor's consideration, in the nap sheet, in many cases, the function to be executed is specified by at least one piece of information out of the posture of the sheet body (2) and whether or not a user exists on the sheet body (2).
[0008] On the other hand, in the said nap sheet, the function to be executed by the operation of the switch unit (12) is automatically determined by using at least one detection signal out of the detection signal of the posture detection unit (10) and the detection signal of the user detection unit (11). Therefore, without providing a switch for switching the function, the execution of a specific function can be easily instructed and operated.
[0009] Incidentally, the said nap sheet may have, for example, the following configuration. That is, it is desirable to include a notification unit (9) for notifying the content of the function determined by the function determination unit (9). Thereby, the person who operates the switch unit (12) can grasp the function executed by the operation of the switch unit (12).
[0010] Furthermore, it is desirable to include a covering part (3) that covers the entire sheet body (2), and the switch unit (12) is provided on the outer surface of the covering part (3) or outside the covering part (3). Incidentally, the reference numerals in the above parentheses are an example showing the correspondence with the specific configuration etc. described in the embodiments described later, and the present disclosure is not limited to the specific configuration etc. indicated by the reference numerals in the above parentheses.

Mode for Carrying Out the Invention
[0012] The following "Embodiments of the Invention" show an example of embodiments belonging to the technical scope of the present disclosure. That is, the invention-specific matters described in the claims are not limited to the specific configurations, structures, etc. shown in the following embodiments.
[0013] This embodiment is an example in which the nap sheet according to the present disclosure is applied to a stationary nap sheet installed indoors. The arrows, hatching, etc. indicating the directions attached to each figure are described to facilitate understanding of the relationship between the figures and the shape of the members or parts.
[0014] Therefore, the nap sheet is not limited to the directions attached to each figure. The directions shown in each figure are the directions in the state where the nap sheet according to this embodiment is installed. The figure with hatching does not necessarily show a cross-sectional view.
[0015] At least the members or parts described with reference numerals are provided with at least one, unless otherwise stated such as "one". That is, when there is no statement such as "one", two or more of the members may be provided. The nap sheet shown in the present disclosure includes components such as at least the members or parts described with reference numerals, and the illustrated structural parts.
[0016] (First Embodiment) <1. Outline of Nap Sheet> The nap sheet 1 includes at least a sheet body 2 and a covering portion 3 as shown in FIG. 1. The sheet body 2 has at least a sheet back 4, a seat cushion 5, an ottoman 6, and an operation panel 7.
[0017] The sheet back 4 is a part for supporting the back of the user. The seat cushion 5 is a part for supporting the buttocks of the user. The ottoman 6 is provided on the front end side of the seat cushion 5 to support the calves and the like of the user.
[0018] The operation panel 7 is an operation part operated by the user. Various operation switches such as an operation switch for changing the posture of the sheet body 2 (hereinafter referred to as a posture switching switch) are provided on the operation panel 7.
[0019] The nap sheet 1 has an electric posture changing mechanism 8 (see FIG. 2) that displaces the postures of the ottoman 6, the seat cushion 5, and the sheet back 4, that is, the posture of the sheet body 2, between a sitting posture (the state shown in FIG. 1) and a nap posture.
[0020] The sitting posture is a posture assumed when the user sits on the sheet body 2. The nap posture is a posture assumed when the user sleeps using the sheet body 2. Specifically, in the sitting posture, at least the sheet back 4 and the ottoman 6 are in a state of standing up more than in the nap posture.
[0021] When the posture switching switch is operated, the posture changing mechanism 8 operates, and the posture of the sheet body 2 automatically becomes the nap posture or the sitting posture. The operation panel 7 provided with the posture switching switch is arranged at a position where it can be easily operated when the user is sitting on the sheet body 2.
[0022] In addition to the posture switching function, the sheet body 2 according to the present embodiment can also execute other functions (for example, a massage function, a stretch function, etc.). The user can execute the other functions by operating the operation panel 7.
[0023] The covering part 3 is a member that covers the entire seat body 2. The covering part 3 is configured to be able to switch between a state where it covers the seat body 2 and a state where the seat body 2 is opened. Specifically, the covering part 3 is configured to have a curtain or an openable door or the like.
[0024] <2. Configuration for external control (see Fig. 2)> As shown in Fig. 2, the operation of the posture changing mechanism 8 is controlled by the control unit 9. The control unit 9 is a controller of a microcomputer system, and is configured to have a CPU, a ROM, a RAM, and the like.
[0025] The software executed by the control unit 9, that is, the CPU, is pre-stored in a non-volatile storage unit (not shown) such as a ROM. Then, when the software is executed by the control unit 9, the operation control of the posture changing mechanism 8, the function determination unit, the notification unit, and the like are realized.
[0026] Connected to the control unit 9 are a posture detection unit 10, a user detection unit 11, a switch unit 12, and a display 13. The posture detection unit 10 detects the posture of the seat body 2 and inputs a signal indicating the detection result to the control unit 9.
[0027] Note that the posture detection unit 10 according to the present embodiment detects the posture of the seat body 2 from the state of the posture changing mechanism 8. Specifically, the posture detection unit 10 is configured by a limit switch, a proximity switch, or the like that indicates the positions of the seat back 4, the seat cushion 5, and the ottoman 6.
[0028] The user detection unit 11 detects whether or not a user exists on the seat body 2 and inputs a signal indicating the detection result to the control unit 9. The user detection unit 11 according to the present embodiment detects the presence of a user by using the load acting on the seat body 2 (particularly, the seat cushion 5).
[0029] The switch unit 12 is an operation unit provided at a part other than the operation panel 7 (in this embodiment, on the outer surface of the covering part 3 or outside the covering part 3). When the switch unit 12 is operated, the function determined by the function determination unit is executed.
[0030] The display 13 is a display or the like that displays information according to the control of the notification unit. The notification unit notifies the content of the function by causing the display 13 to display the content of the function determined by the function determination unit.
[0031] <Function determination unit> The function determination unit realizes a function of determining a function (hereinafter referred to as an execution function) to be executed when the switch unit 12 is operated. Specifically, the function determination unit determines the function using at least one of the detection signals of the posture detection unit 10 and the user detection unit 11.
[0032] Specifically, as shown in FIG. 3, it is as follows. That is, the detection signals of the posture detection unit 10 are two types: a signal indicating a sitting posture and a signal indicating a dozing posture. The detection signals of the user detection unit 11 are two types of signals indicating whether a user exists or not.
[0033] Therefore, there are four types of combinations of the detection signals of the posture detection unit 10 and the user detection unit 11. And the function determination unit, that is, the control unit 9, determines the function corresponding to the current combination among the four types of combinations as the execution function.
[0034] For example, when the user is present on the seat body 2 and the other functions are not being executed on the seat body 2, the control unit 9 determines the function of calling the user as the execution function.
[0035] For example, when the user is present on the seat body 2 and the seat body 2 is executing the other functions, the control unit 9 determines the function of stopping the other functions as the execution function.
[0036] For example, when the user is not present on the seat body 2 and the seat body 2 is in the dozing posture, the control unit 9 determines the function of changing the seat body 2 to the sitting posture as the execution function.
[0037] For example, when the user is not present on the seat body 2 and the seat body 2 is in the sitting posture, the control unit 9 determines the function of changing the seat body 2 to the sleep mode as the execution function. Note that the sleep mode is an operation mode for reducing power consumption.
[0038] <3. Features of the dozing seat according to the present embodiment> In the dozing seat 1, in many cases, the function to be executed is specified based on at least one of the information on the posture of the seat body 2 and whether the user is present on the seat body 2.
[0039] On the other hand, in the dozing seat 1 according to the present embodiment, since the execution function is automatically determined using the detection signal of the posture detection unit 10 and the detection signal of the user detection unit 11, it is possible to easily instruct and operate the execution of a specific function without separately providing a switch for switching the function.
[0040] The dozing seat 1 includes a notification unit that notifies the content of the function determined by the function determination unit. Thereby, the person operating the switch unit 12 can grasp the function executed by the operation of the switch unit 12.
[0041] (Other embodiments) In the above-described embodiment, the execution function is determined using the detection signal of the posture detection unit 10 and the detection signal of the user detection unit 11. However, the present disclosure is not limited to this. That is, the present disclosure may be configured such that the execution function is determined using, for example, the detection signal of the posture detection unit 10 or the detection signal of the user detection unit 11.
[0042] The posture detection unit 10 according to the above-described embodiment was configured by a limit switch, a proximity switch, or the like. However, the present disclosure is not limited thereto. That is, the present disclosure may be configured to detect the posture of the seat body 2 by, for example, photographing the seat body 2 with a camera and analyzing the photographed image.
[0043] The user detection unit 11 according to the above-described embodiment detected the presence of a user by using the load acting on the seat body 2. However, the present disclosure is not limited thereto. That is, the present disclosure may be configured to detect the presence or absence of a user by, for example, photographing the seat body 2 with a camera and analyzing the photographed image.
[0044] In the above-described embodiment, an example in which the nap sheet according to the present disclosure is applied to a stationary seat was shown. However, the application of the invention disclosed in this specification is not limited thereto. That is, the present disclosure is applicable to, for example, vehicle seats used in vehicles such as automobiles, railway vehicles, ships, and aircraft.
[0045] Furthermore, the present disclosure only needs to conform to the gist of the disclosure described in the above-described embodiment and is not limited to the above-described embodiment. Therefore, a configuration in which at least two of the above-described plurality of embodiments are combined, or a configuration in which any one of the configuration elements shown or the configuration elements described with reference numerals in the above-described embodiment is abolished may be used.
