Summary of the Invention

Problems to be Solved by the Invention

[0004] In order to grasp the condition of the occupant after a collision, measuring vital signs such as arterial oxygen saturation SpO2 and pulse rate is an effective means, for example. However, when measuring vital signs in a non-contact state using, for example, a camera, there is a concern that the occupant may go out of the imaging angle of the camera or a foreign object may intervene between the camera and the occupant after the collision. The same problem occurs when measuring vital signs in a non-contact state using a detection wave such as an electromagnetic wave. On the other hand, it has also been proposed to incorporate a sensor for measuring vital signs in the seat sheet. In this case, however, there is a concern that accurate measurement of vital signs may not be possible due to the occupant's clothing. In this regard, if a sensor that directly contacts, for example, the occupant's finger is used, the measurement accuracy of vital sign measurement is ensured. However, it is difficult for an occupant who has been injured or is in a panic state after a collision to extend their hand to the vital sign measurement sensor of their own will. In view of the above problems, an object of the present invention is to provide a vital sign measurement device that allows a subject to easily measure vital signs after a collision.

Means for Solving the Problems

[0005] In order to solve the above problems, a vital sign measurement device according to an aspect of the present invention includes a seat surface portion on which the thigh and buttocks of the subject are placed, and a seat back portion arranged along the back of the subject.

Mode for Carrying Out the Invention

[0012] Hereinafter, an embodiment of a vital sign measuring device to which the present invention is applied will be described. The vital sign measuring device of the embodiment is provided, for example, on a seat for the front seats (driver's seat, passenger seat) of an automobile such as a passenger car, and measures the vital signs of an occupant (subject) sitting on the seat after the occurrence of a collision accident.

[0013] FIG. 1 is a schematic external perspective view of a vehicle seat on which the vital sign measuring device of the embodiment is provided, and shows a state in which the upper body of the occupant is reclined against the seat back. The seat 1 has a seat surface portion 10, a seat back 20, a headrest 30, a seat trim 40, and the like. The seat 1 is attached to a vehicle body (not shown) in a posture where the occupant 100 faces the front side of the vehicle. The seat surface portion 10 is a portion on which the buttocks 110 and thighs 120 of the occupant 100 are placed. The seat surface portion 10 has a cushion placed on the seat frame F. The seat back 20 is a backrest-shaped portion arranged along the back of the upper body 130 of the occupant 100. The seat back 20 is formed to extend upward from the vicinity of the rear end portion of the seat surface portion 10. The headrest 30 is provided to protrude upward from the upper end portion of the seat back 20, and is a portion that supports the rear portion of the head 140 of the occupant 100.

[0014] The seat trim 40 is provided at the lower portion of the seat surface portion 10, and is a cover-shaped member that covers the seat frame F provided inside the seat 1, a seat rail (not shown), a drive mechanism for changing the seat position, and the like. The seat frame F is a frame-shaped structural member provided at the lower part of the seat surface portion 10 and formed of, for example, a metal member having a closed cross section. The seat trim 40 has side surface portions 41, front surface portion 42, and the like. The side surface portion 41 is a surface portion formed by extending downward from the side edge portion of the seat surface portion 10. The side surface portion 41 is disposed facing the side of the vehicle. The front surface portion 42 is a surface portion formed by extending downward from a region near the side end portion at the front edge portion of the seat surface portion 10. The front surface portion is disposed facing the front side of the vehicle. At the rear part of the side surface portion 41, a switch 43 for changing the seat position such as the front-rear position, up-down position, front-rear direction inclination of the seat surface portion 10, and the inclination (reclining angle) of the seat back 20 of the occupant 100 is provided.

[0015] The seat 1 is provided with, for example, a sensor for measuring the vital signs of the occupant 100 after the occurrence of a collision accident. As the vital signs, for example, pulse, arterial oxygen saturation SpO2, etc. can be measured. The seat 1 has a rear side sensor 200, a front side sensor 300, a front sensor 400, and the like.

[0016] The rear side sensor 200 is provided at the rear part of the side surface portion 41 of the seat trim 40. The rear side rear sensor 200 typically measures the vital signs of the occupant 100 in a state where the upper body 130 of the occupant 100 leans against the seat back 20 and the arm 150 hangs down to the side of the seat surface portion 10 after the occurrence of a collision accident. The rear side sensor 200 has an opening 210, a lever 220, and the like. The opening 210 is a portion into which the finger 160 of the occupant 100 is inserted when measuring the vital signs. The probe 230 (see FIGS. 6 to 8) of the fingertip type pulse oximeter, which is the detection part of the rear side rear sensor 200, is provided inside the opening 210. The openings 210 can be configured to be arranged in three in a way that, for example, the index finger, middle finger, and ring finger of the occupant 100 can be inserted. (The same applies to the openings 310 and 410 described later.) The openings 210 are arranged, for example, along the vehicle's longitudinal direction. The openings 210 are disposed below the switch 43.

[0017] The lever 220 is a member that guides the fingers 160 of the occupant 100 to be inserted into the openings 210 during a collision. The lever 220 is disposed above the openings 210 and the switch 43. Generally, in the human body, when the arm hangs down to the side of the torso in a relaxed state, the hand often faces with the palm facing inward (toward the torso side / hip side). Therefore, the longitudinal direction of the lever 220 is arranged along the vehicle's longitudinal direction. Normally (before a collision occurs), the lever 220 is housed in or adjacent to the side surface portion 41 of the seat trim 40, and is extended outward in the vehicle width direction so as to protrude from the side surface portion 41 after a collision occurs. The configuration, operation, and function of the lever 220 will be described in detail later.

[0018] The front side sensor 300 is provided at the front portion of the side surface portion 41 of the seat trim 40. Typically, the front side sensor 300 measures the vital signs of the occupant 100 when the upper body 130 of the occupant 100 has fallen forward and the arm 150 has hung down to the side of the seat surface portion 10 after a collision accident has occurred. FIG. 2 is a schematic external perspective view of a vehicle seat provided with the vital sign measuring device according to the embodiment, showing a state where the upper body of the occupant has fallen forward and the arm has hung down to the side of the seat surface portion. The front side sensor 300 has openings 310, a lever 320, and the like. The opening 310 is a portion into which the fingers 160 of the occupant 100 are inserted when measuring the vital signs. The probe (not shown) of the fingertip pulse oximeter, which is the detection unit of the front side sensor 300, is provided inside the opening 310. For example, three openings 310 are arranged along the vehicle longitudinal direction.

[0019] The opening 310 of the front side sensor 300 is arranged at a position higher in the vertical direction than the opening 210 of the rear side sensor 200. For example, the opening 210 is arranged at a low position with respect to the seat frame F, while the opening 310 can be arranged at a high position with respect to the seat frame F. The difference in height between the openings 210 and 310 is set in consideration of the difference in the height of the fingers 160 between the state where the upper body 130 of the occupant 100 leans against the seat back 20 and the state of forward inclination.

[0020] The lever 320 is a member that guides the finger 160 of the occupant 100 to the opening 310 during a collision. The lever 320 is located above the opening 310 and is arranged near the upper edge of the side surface portion 41 of the seat trim 40. The longitudinal direction of the lever 320 is arranged along the vehicle longitudinal direction. Normally, the lever 320 is housed in or adjacent to the side surface portion 41, and is extended upward so as to protrude from the side surface portion 41 after a collision occurs.

[0021] The front sensor 400 is provided on the front surface portion of the seat trim 40. Typically, after a collision accident occurs, when the upper body 130 of the occupant 100 falls forward, the front sensor 400 measures the vital signs of the occupant 100 in a state where the arm 150 hangs down along the outside of the thigh 120 in front of the seat surface portion 10. Figure 3 is a schematic plan view of the side portion of the seat surface portion in a state where the grip portions of the respective sensors protrude in the vehicle seat according to the embodiment. The front sensor 400 has an opening 410, a lever 420, etc. The opening 410 is a portion into which the finger 160 of the occupant 100 is inserted when measuring vital signs. A probe (not shown) of a fingertip pulse oximeter, which is a detection unit of the front sensor 400, is provided inside the opening 410. For example, three openings 410 are arranged along the vehicle width direction.

[0022] The lever 420 is a member that guides the finger 160 of the occupant 100 to the opening 410 during a collision. The lever 420 is located above the opening 410 and is disposed near the upper edge of the front surface portion 42 of the seat trim 40. Generally, in the human body, when the arm hangs down in front of the torso in a relaxed state, the back of the hand often faces the front side. Therefore, the longitudinal direction of the lever 420 is arranged along the vehicle width direction. Normally, the lever 420 is housed in or adjacent to the front surface portion 42, and is extended forward of the vehicle so as to protrude from the front surface portion 42 after a collision occurs.

[0023] The above-described levers 220, 320, and 420 are extended so as to protrude from the seat 1, for example, in response to the acceleration acting on the vehicle body during a collision. FIG. 4 is a schematic external perspective view of a vehicle seat provided with the vital sign measuring device according to the embodiment, showing a state in which the levers of the respective sensors are extended. FIG. 5 is a schematic plan view of a side portion of the seat surface portion in a state where the grip portions of the respective sensors protrude in the vehicle seat according to the embodiment.

[0024] The lever 220 of the rear side sensor 200 is extended outward in the vehicle width direction from the side surface portion 41 of the seat trim 40. In the extended state, the lever 220 is supported by the stay 221. The stay 221 is provided so as to protrude inward in the vehicle width direction from the rear end of the lever 220 on the vehicle rear side. A gap is formed between the lever 220 and the side portion 41 of the seat trim 40 into which the thumb of the occupant 100 can be inserted, and the thumb can be inserted into this gap from the upper side or the front side of the vehicle.

[0025] The lever 320 of the front side sensor 300 is extended upward from the side portion 41 of the seat trim 40. In the extended state, the lever 320 is supported by the stay 321. The stay 321 is provided so as to protrude downward from the rear end of the lever 230 on the rear side of the vehicle. The lever 320 is arranged to be sandwiched between the fingers 160 and the thumb of the occupant 100 when the upper body 130 of the occupant 100 falls forward and the arm 150 drops.

[0026] The lever 420 of the front sensor 400 is extended forward from the front portion 42 of the seat trim 40. In the extended state, the lever 420 is supported by the stay 421. The stay 421 is provided so as to protrude rearward from the inner end of the lever 420 in the vehicle width direction. A gap is formed between the lever 420 and the front portion 42 of the seat trim 40 into which the thumb of the occupant 100 can be inserted, and the thumb can be inserted into this gap from the upper side or the outer side in the vehicle width direction.

[0027] Hereinafter, regarding the function of the levers 220, 320, and 420 described above to guide the finger 160 of the occupant 100 to the measurement position where it contacts the probe, the lever 220 of the rear side sensor 200 will be taken as an example for explanation. Note that the levers 320 and 420 have substantially the same operations and effects except that the protruding directions from the seat 1 are different. FIG. 6 is a schematic cross-sectional view of the rear side sensor unit in the vital sign measurement device of the embodiment, showing the state in normal times (before a collision occurs). The rear side sensor 200 further includes a spring 222, a lock mechanism 223, a support shaft 224, a probe 230, a plate 231, an interlocking mechanism 232, and the like.

[0028] The spring 222 is provided at the end of the stay 221 opposite to the lever 220 side, and biases and presses the stay 221 in the feeding direction of the lever 220 (the outer side in the vehicle width direction in the case of the lever 220). The locking mechanism 223 is configured by pressing a weight by a biasing means such as a spring in a recess formed in the stay 221. During normal use of the vehicle (except when a collision occurs), the stay 221 is locked to prevent the lever 220 from being extended by the spring 222, and when a collision occurs, the lock of the stay 221 is released to allow the lever 220 to be extended by the spring 222. The locking mechanism 223 is configured to release the lock when an acceleration (for example, about 10 G) that does not occur during normal use of the vehicle occurs in the vehicle body. The support shaft 224 is a rotation center shaft that rotatably supports (oscillates) the stay 221 in the downward direction of the lever 220 in a state where the lever 220 is extended outward in the vehicle width direction and protrudes from the side surface portion 41 of the seat trim 40.

[0029] The probe 230 is a detection unit that measures vital signs from the finger 160 of the occupant 100. The probe 230 has functions such as detecting the arterial oxygen saturation SpO2 by irradiating the nail portion of the finger 160 of the occupant 100 with light emitted by a red LED, and acquiring the pulse rate. The probe 230 is provided on the lower surface portion of the opening 210. The plate 231 is a pressing member that abuts on the fingerprint side (upper side) of the finger 160 of the occupant 100 and presses downward to press the nail portion against the probe 230. The plate 231 is adjacent to the upper surface portion of the opening 210 and is attached so as to be relatively displaceable in the vertical direction with respect to the opening 210. The interlocking mechanism 232 is interlocked with the rotation of the stay 221 around the support shaft 224 and moves the plate 231 downward. As the interlocking mechanism 232, for example, a region inside the vehicle width direction from the support shaft 224 of the stay 221 and the lower surface portion of the plate 231 may be connected by a cord-like member having flexibility and elasticity, and the plate 231 may be configured to be pulled downward in accordance with the rotation of the stay 221. However, the configuration of the interlocking mechanism 232 is not limited to this and can be appropriately changed.

[0030] FIG. 7 is a schematic cross-sectional view of the rear side sensor unit in the vital sign measuring device of the embodiment, showing the state immediately after a collision occurs. After a collision occurs, the locking mechanism 223 is released according to the acceleration acting on the vehicle body, and the lever 220 and the stay 221 are extended in the vehicle width direction by the spring 222. As a result, the lever 220 protrudes from the seat 1 in a state of having a gap with the side surface portion 41 of the seat trim 40. When the impact of the collision causes the occupant 100 to become unconscious, the body loses strength, and the upper body 130 leans against the seat back 20 and the arm 150 descends due to its own weight, the lever 220 is sandwiched between the fingers 160 and the palm 170 and the thumb 180.

[0031] FIG. 8 is a schematic cross-sectional view of the rear side sensor unit in the vital sign measuring device of the embodiment, showing the state during vital sign measurement. The lever 220 rotates in a direction of descending around the support shaft 224 with respect to the state shown in FIG. 7 due to the own weight of the arm 150 of the occupant 100. At this time, the spring 222 and the locking mechanism 223 can be configured to release the engagement and connection with the stay 221 so as not to prevent the rotation of the stay 221. The finger 160 of the occupant 100 rotates around the support shaft 224 following the rotation of the lever 220, and the fingertip is guided to be inserted and accommodated in the opening 220. Note that in a state where the occupant 100 is relaxed, the joints of the normal finger 160 often bend loosely, so the fingertip can be inserted into the opening 220 by utilizing the bending of this joint.

[0032] In response to the rotation of the stay 221 around the support shaft 224, the interlocking mechanism 232 moves the plate 231 downward. As a result, the fingertips of the fingers 160 of the occupant 100 are pressed and restrained so that the claw portions are crimped to the probe 230. Further, in response to the completion of the rotation of the stay 221 (the completion of the insertion of the finger 160 into the opening 210), the probe 230 starts measuring vital signs such as the arterial oxygen saturation SpO2 and pulse of the occupant. Note that the measured vital signs can be configured to be automatically transmitted to a base station (not shown) provided remotely via a communication device (not shown). The base station can share the vital signs of the occupant obtained from the vehicle in which a collision accident has occurred with organizations such as emergency, medical, and police organizations.

[0033] In addition, the levers 320 and 420 of the front side sensor 300 and the front sensor 400 also have a function of being extended so as to protrude from the seat 1 at the time of a collision and guiding the fingers of the occupant 100 to be inserted into the openings 310 and 410, similar to the lever 220 described above.

[0034] As described above, according to the present embodiment, the following effects can be obtained. (1) Even when the occupant 100 is in a state of being exhausted, if the hand drops and the levers 220, 320, and 420 are sandwiched between the thumb 180 and the palm 170 or the fingers 160, the levers 220, etc. guide the finger 160 to the measurement position. Therefore, even when the consciousness of the occupant 100 is in a drowsy state or the like, the vital signs can be easily measured. (2) The levers 220, etc. are stored in the seat trim 40 of the seat 1 during normal times and protrude from the seat 1 in response to the occurrence of a collision. Thus, it is possible to prevent the levers 220, etc. from deteriorating the usability of the vehicle during normal use of the vehicle or getting caught on the body, clothing, etc. of the occupant 100. (3) By providing the plate 231 that presses against the finger 160 of the occupant 100 so as to crimp it to the probe 230, the finger 160 of the occupant 100 can be restrained at the measurement position, and the vital sign measurement can be performed more reliably. (4) When the finger 160 of the occupant 100 guided by the lever 220 or the like is inserted into the opening 210 or the like formed in the seat trim 40, the positioning accuracy of the finger 160 with respect to the probe 230 or the like is improved, and the vital sign measurement can be performed more reliably. (5) By providing the rear side sensor 200, the front side sensor 300, and the front sensor 400, in a state where the occupant 100 relaxes and the upper body 130 leans against the seat back 20, or in a state where the upper body 130 falls forward, the above-described effects can be obtained more reliably by arranging the sensor at a location where the arm 150 naturally hangs down.

[0035] (Modification) The present invention is not limited to the embodiments described above, and various modifications and changes are possible, and these are also within the technical scope of the present invention. (1) The shape, structure, arrangement, material, manufacturing method, quantity, etc. of each member constituting the vital sign measuring device and the seat are not limited to the above-described embodiments, and can be appropriately changed. (2) The configuration of the sensor for measuring the vital sign in the embodiment and the mechanism for guiding the finger of the subject to the sensor are examples, and can be appropriately changed. In the embodiment, the arterial oxygen saturation concentration and the heart rate are measured as vital signs, but the present invention does not require the measurement of both, and may be configured to measure only one of them. Also, other vital signs may be additionally or selectively measured. For example, blood pressure may be measured. (3) In the embodiment, the rear side sensor, the front side sensor, and the front sensor are provided as sensors for measuring the vital sign, but one or two of these may be provided. Also, other sensors may be additionally provided in addition to these. (4) The configuration of the mechanism for guiding the finger of the person to be measured to the measurement position is not limited to the configuration of the embodiment and can be appropriately changed. For example, the shape of the lever, the feeding direction, the configuration of the mechanism for performing the feeding operation, the movement locus of the lever when guiding the finger, etc. can be appropriately changed. Further, in the embodiment, each lever is configured to be fed by a spring in response to the impact of a collision, but it is not limited thereto. For example, various actuators of an electric actuator may be used to feed the lever. Further, for example, when a pre-crash determination is established based on the output of a sensor such as a stereo camera device or a millimeter-wave radar device (when there is a precursor to a collision), it may be configured to be fed prior to an actual collision. Furthermore, the lever may be configured to protrude from the seat during normal use of the vehicle. In this case, the mechanism for feeding the lever becomes unnecessary, and the device configuration can be simplified. (5) In the embodiment, the seat was provided, for example, for the front seat of an automobile such as a passenger car, but the type of vehicle and the installation location of the seat are not limited thereto. For example, the seat may be installed in the second row or later of a passenger car.
