Summary of the Invention

Problems to be Solved by the Invention

[0004] For example, when stretching for awakening a user during reclining, if the output required for stretching is determined only by weight, it is difficult to give an appropriate stretching effect for awakening to a thin and tall person or a fat and short person respectively. The present disclosure discloses an example of a reclining seat in view of this point.

Means for Solving the Problems

[0005] A reclining seat including a seat back (4) and a seat cushion (5) and capable of displacing at least the seat back (4) between a reclining posture for reclining and a seating posture for sitting preferably includes at least one of the following constituent elements.

[0006] That is, the constituent element includes a pressing mechanism (3) built in the seat back (4) and capable of exerting a protruding function of protruding the surface of the seat back (4) toward the user, a physical condition sensor (10) provided in at least one of the seat back (4) and the seat cushion (5) and detecting information related to the physical condition including information on at least one of the user's seat height and body width, and a control unit (9) for controlling the operation of the pressing mechanism (3), the control unit (9) being capable of exerting a protruding amount changing function of changing the protruding amount of the pressing mechanism (3) in the dozing posture using the detection value of the physical condition sensor (10).

[0007] Thereby, in the dozing seat, it becomes possible to give a stretching effect for awakening suitable for the user's physical condition. Note that the stretch is realized by protruding the surface of the seat back (4) toward the user.

[0008] Note that the dozing seat may have the following configuration. That is, instead of the physical condition sensor (10), a configuration may be provided with an input unit (7) for inputting information related to the physical condition including information on at least one of the user's seat height and body width.

[0009] Further, instead of the physical condition sensor (10), a configuration may be provided with a receiving unit (11) capable of receiving information related to the physical condition including information on at least one of the user's seat height and body width by wireless communication or wired communication.

[0010] Further, the pressing mechanism (3) includes a first airbag (3A) extending in the seat width direction, a second airbag (3B) extending in a direction orthogonal to the extending direction of the first airbag (3A), and pumps (3C, 3D) for supplying air to the first airbag (3A) and the second airbag (3B). The control unit (9) changes the protruding amount by adjusting the amount of air supplied to the first airbag (3A) and the second airbag (3B) to change the inflation amount of the first airbag (3A) and the second airbag (3B). Further, it is desirable that the control unit (9) inflates the second airbag (3B) after inflating the first airbag (3A).

[0011] As a result, it may be possible to effectively provide a stretching effect for awakening. Incidentally, the reference numerals in each of the above parentheses are examples showing the correspondence with the specific configuration and the like described in the embodiments described later, and the present disclosure is not limited to the specific configuration and the like indicated by the reference numerals in the parentheses.

Modes for Carrying Out the Invention

[0013] 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 and the like described in the claims are not limited to the specific configurations, structures, and the like shown in the following embodiments.

[0014] This embodiment is an example in which the nap sheet according to the present disclosure is applied to a stationary nap sheet installed indoors. Arrows, hatching, etc. indicating directions attached to each figure are described to facilitate understanding of the relationship between each figure and the shape of members or parts.

[0015] 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.

[0016] At least one member or part described with a reference sign is provided, unless otherwise specified, such as "one". That is, when there is no such specification as "one", two or more of such members may be provided. The nap sheet disclosed herein includes at least components such as members or parts described with reference signs, and structural parts shown in the drawings.

[0017] (First Embodiment) <1. Overview of Nap Sheet> As shown in FIG. 1, the nap sheet 1 includes at least a sheet body 2, a pressing mechanism 3, a control unit 9, etc. The sheet body 2 includes at least a seat back 4, a seat cushion 5, an ottoman 6, an operation panel 7, etc.

[0018] The seat 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 of the user.

[0019] Each of the seat back 4 and the ottoman 6 is displaceable with respect to the seat cushion 5. Specifically, the seat back 4 is swingably connected to the rear end side of the seat cushion 5. The ottoman 6 is swingably connected to the front end side of the seat cushion 5.

[0020] Each of the seat back 4 and the ottoman 6 according to the present embodiment is displaceable electrically. Specifically, electric motors 8A and 8B are provided in the sheet body 2. The electric motor 8A displaces the seat back 4. The electric motor 8B displaces the ottoman 6.

[0021] Then, the nap sheet 1 has a function of displacing the postures of the ottoman 6, the seat cushion 5, and the seat back 4, that is, the posture of the sheet body 2, between the sitting posture and the nap posture (see FIG. 1).

[0022] The sitting posture is the posture assumed when the user sits on the seat body 2. The dozing posture is the posture assumed when the user sleeps using the seat body 2. Specifically, in the sitting posture, the seat back 4 and the ottoman 6 are in a state of standing up from the dozing posture.

[0023] When the seat body 2 is in the sitting posture and the posture switching switch (not shown) is operated, the seat body 2 becomes the dozing posture. When the seat body 2 is in the dozing posture and the posture switching switch is operated, the seat body 2 becomes the sitting posture.

[0024] The operation panel 7 is an operation unit operated by the user. Various operation switches such as a posture switching switch, a display device, and an input device are provided on the operation panel 7. The operation panel 7 can exchange signals with the control unit 9.

[0025] The pressing mechanism 3 is built into the seat back 4. The pressing mechanism 3 is a mechanism capable of exerting a protruding function (hereinafter referred to as a stretch function) of protruding the surface of the seat back 4 toward the user.

[0026] Specifically, the pressing mechanism 3 is configured to include at least a first airbag 3A, a second airbag 3B, a first pump 3C, and a second pump 3D. As shown in FIG. 2, the first airbag 3A is an airbag (air bladder) extending in the seat width direction.

[0027] The second airbag 3B is an airbag (air bladder) extending in a direction orthogonal to the extending direction of the first airbag 3A. The first pump 3C supplies air to the first airbag 3A as shown in FIG. 1. The second pump 3D supplies air to the second airbag 3B.

[0028] When air is supplied to at least one of the first airbag 3A and the second airbag 3B and the airbag expands, the surface of the seat back 4 protrudes toward the user. Each of the airbags 3A and 3B is provided with a discharge valve (not shown) for discharging the filled air inside. Thereby, the inflated airbag can be contracted.

[0029] <2. Control unit and stretch control unit, etc.> <2.1 Configuration of control unit, etc.> The control unit 9 is a controller that controls the operation of the electric motors 8A and 8B and the pressing mechanism 3, that is, the first pump 3C, the second pump 3D, and the discharge valve. As shown in FIG. 3, the control unit 9 is a controller of the microcomputer type and includes a CPU, a ROM, a RAM, etc.

[0030] The software executed by the CPU is stored in advance in a non-volatile storage unit (not shown) such as a ROM. And when the software is executed by the CPU, that is, the control unit 9, a posture changing unit, a stretch control unit, etc. are realized.

[0031] The posture changing unit is a functional block that controls the operation of the electric motors 8A and 8B based on signals from a posture change switch or the like. The stretch control unit is a functional block that realizes the stretch function by controlling the operation of the pressing mechanism 3.

[0032] The nap seat 1 also includes a physique sensor 10, a receiving unit 11, etc. The physique sensor 10 detects physique information. The physique information refers to information related to the physique including at least one of the seat height and the body width of the user. Specifically, the physique sensor 10 is composed of, for example, pressure sensors respectively embedded at a plurality of locations on the seat back 4.

[0033] The receiving unit 11 is a receiving unit for receiving the physical information of the user by wireless communication or wired communication. Specifically, the receiving unit 11 receives the physical information from a portable terminal device (e.g., a smartphone) used by the user.

[0034] That is, an application for inputting and transmitting information indicating physical characteristics such as weight, height, sitting height, and body width is pre-installed in the smartphone. When the user inputs their physical information into the smartphone via the application, the application transmits the input physical characteristics to the receiving unit 11.

[0035] The operation panel 7 is provided with an input function for the user to input physical information. That is, the operation panel 7 also functions as an input unit for the user to input physical information. And the detection signal of the physical sensor 10, the output signal of the operation panel 7, and the signal indicating the information received by the receiving unit 11 are input to the control unit 9.

[0036] <2.2 Stretch control unit> The stretch function is a function that is executed when the wake-up mode is executed when the seat body 2 is in the dozing posture. The wake-up mode is a mode for waking up the user during sleep (dozing). The wake-up mode is executed at the wake-up time set and input by the user via the operation panel 7.

[0037] The stretch function is a function of inflating at least one of the first airbag 3A and the second airbag 3B to project the surface of the seat back 4 toward the user. And the amount of projection at the time of executing the stretch function, that is, the amount of air supplied, is changed and adjusted according to the physical information.

[0038] That is, the control unit 9 changes and adjusts the amount of air supplied to the first airbag 3A and the second airbag 3B by using at least one of the physical condition information detected by the physical condition sensor 10 (hereinafter referred to as sensor information), the physical condition information input to the operation panel 7 (hereinafter referred to as panel information), and the physical condition information received by the receiving unit 11 (hereinafter referred to as received information).

[0039] Note that when neither the panel information nor the received information can be used, the control unit 9 uses the sensor information. However, when the panel information or the received information can be used, the control unit 9 uses the panel information or the received information.

[0040] Then, when the physical condition becomes larger, the control unit 9 increases the amount of air supplied to the first airbag 3A and the second airbag 3B accordingly. As a result, the protruding amount of the pressing mechanism 3 increases according to the increase in the physical size (see FIGS. 4A, 4B, 5A, and 5B).

[0041] The control unit 9 according to the present embodiment sets the timing of inflating the first airbag 3A and the timing of inflating the second airbag 3B to different timings. Specifically, after inflating the first airbag 3A, the control unit 9 inflates the second airbag 3B when the first airbag 3A contracts.

[0042] <3.
