Description

  The present invention relates to a vehicle seat structure including a living body detection sensor that detects biological information of an occupant.

  For example, a technique for detecting a biological condition (vital sign) of an occupant (driver) of a vehicle, for example, breathing or heartbeat of the occupant is known (for example, Patent Document 1). In this technique, the occupant's respiration and heartbeat can be monitored using a living body detection sensor, and the vehicle can be controlled in accordance with the occupant's physical condition management and the occupant's situation. As a living body detection sensor, a sensor that irradiates a physical wave (electromagnetic wave, sound wave) toward an occupant and detects respiration or heartbeat is applied. The living body detection sensor is attached to a vehicle seat (seat cushion, seat back, etc.), and can irradiate electromagnetic waves or the like toward a predetermined part (for example, chest) of the occupant.

  In the conventionally proposed technology for detecting a vital sign of an occupant, a living body detection sensor is provided on a vehicle seat, and there is no significant change in the positional relationship between the biological detection sensor and the occupant during normal driving. Can accurately detect respiration and heartbeat.

  However, if the relative position of the seat and the occupant changes when the vehicle collides, etc., the positional relationship between the living body detection sensor and the occupant (irradiation direction of electromagnetic waves, etc.) may change significantly, and the vital sign of the occupant is detected. It may be impossible to do so. For this reason, the technique for detecting the vital sign of the occupant that has been proposed in the past is not supposed to detect the vital sign of the occupant in a situation where the relative position of the seat and the occupant changes due to a vehicle collision or the like. It was technology.

For this reason, the living body detection sensor 4 is in a state in which movement in the front-rear direction of the vehicle is restricted with respect to the driver seat 1.

  The living body detection sensor 4 is controlled when the driver seat 1 is moved in the front-rear direction of the vehicle by the slide rail 10 because the sensor support member 5 restricts the movement of the vehicle in the front-rear direction of the vehicle. It follows and moves with the seat 1. Therefore, regardless of the position of the driver's seat 1 in the front-rear direction, that is, regardless of the position of the driver's seat 1 adjusted / changed due to differences in the physique of the seated occupant, the driver's seat 1 (seats The positional relationship between the occupant) and the biological detection sensor 4 and the positional relationship in the vehicle width direction of the biological detection sensor 4 in the console box 3 can be maintained in a predetermined relationship.

  As shown in FIGS. 2 and 3A, 3B, and 3C, the sensor support member 5 includes a pair of long connecting members 12 that extend toward the console box 3 and are fixed to the driver seat 1. Has been. A base end portion of the pair of long connecting members 12 is fixed to the side surface portion of the driver seat 1 facing the passenger compartment side of the seat pan 8 and the console box 3 so as to be orthogonal to the side surface portions. The members 12 are arranged in parallel at a predetermined interval. The living body detection sensor 4 is provided with a fixing portion 13 having a shaft portion and a retaining portion, and the fixing portion 13 is disposed between the pair of long connecting members 12.

  That is, as shown in FIGS. 3B and 3C, the shaft portion 13 a of the fixed portion 13 is arranged between the pair of long connecting members 12, and the shaft portion 13 a is interposed between the pair of long connecting members 12. In a state of being interposed, the pair of long connecting members 12 are sandwiched between the living body detection sensor 4 and the retaining portion 13b. Thereby, the biological detection sensor 4 is supported movably along the longitudinal direction of the pair of long connecting members 12, and the rotation of the biological detection sensor 4 is restricted.

  The long connecting member 12 is formed of an elastic body such as a leaf spring, and as shown in FIG. 2, the long connecting member 12 penetrates into the console box 3 from the opening of the side portion of the console box 3, and the distal end portions 12 a of the pair of long connecting members 12. Is a curved portion curved downward. And the control wall material 14 as a control member extended in the front-back direction of a vehicle from the console box 3 or the bottom part of a vehicle body is provided in the approximate center part of the vehicle width direction of the console box 3. As shown in FIG. The regulation wall member 14 is disposed along the slide rail 10 and the guide guide member 11, and is formed of a material harder than the long connecting member 12 at a position higher than the position of the long connecting member 12. Movement of the front end portion 12a of the pair of long connecting members 12 in the vehicle width direction (passenger seat 2 side) by the restriction wall member 14 facing at least from the front end position to the rear end position of the guide guide member 11 in the vehicle width direction Movement) is regulated.

  By using the sensor support member 5 described above, the living body detection sensor 4 is supported slidably in the longitudinal direction by a pair of long connecting members 12 extending in the width direction of the vehicle, and the living body detection sensor 4 is moved in the width direction of the vehicle. The vehicle is movable and is restricted from moving in the front-rear direction of the vehicle. And when the driver's seat 1 moves to the center side of the vehicle (passenger seat 2), the curved tip 12a of the long connecting member 12 contacts the regulating wall member 14 and bends downward. The movement of the long connecting member 12 toward the center of the vehicle is restricted, and the long connecting member 12 is prevented from entering the passenger seat 2 side.

The state of operation of the vehicle seat structure will be described with reference to FIGS.
As shown in FIG. 4A, the long connecting member 12 is provided near the front of the vehicle on the console box 3 side of the driver's seat 1 (seat pan 8). Thereby, living body detection sensor 4 can irradiate an irradiation wave to the range of a crew member's chest to a thigh. Further, the irradiation wave of the living body detection sensor 4 passes through the resin member and the like but does not pass through the metal member. Therefore, the seat back portion extends substantially vertically from the rear end portion of the seat cushion portion of the seat pan 8 of the driver seat 1. Interference with the metal member can be avoided.

  When the driver's seat 1 (seat pan 8) is at the front end, the living body detection sensor 4 is held by the long connecting member 12 of the sensor support member 5 and is positioned at the front end of the guide guide member 11 of the console box 3. . As shown in FIG. 4B, when the driver's seat 1 (seat pan 8) moves to the rear end, the living body detection sensor 4 is held by the long connecting member 12 of the sensor support member 5, and the driver's seat. 1 (seat pan 8) is moved, the guide guide member 11 of the console box 3 is moved, and the guide guide member 11 is moved to the rear end.

  The length of the space in the vehicle front-rear direction is set so that the guide guide member 11 corresponds to the movement amount of the long connecting member 12 according to the front-rear slide amount of the seat slide position. Further, at least the opening in the longitudinal direction of the vehicle through which the long connecting member 12 is inserted into the console box 3 is set in the side surface portion of the console box 3.

  Whether the driver's seat 1 (seat pan 8) is at the front end or the driver's seat 1 (seat pan 8) is moved to the rear end, the living body detection sensor 4 is in the vehicle width direction of the console box 3. The state of being arranged at the same position (the state of the positional relationship being a predetermined relationship) is maintained. For this reason, the electromagnetic wave irradiation range X of the living body detection sensor 4 does not depend on the position of the driver's seat 1 in the front-rear direction, that is, at the position of the driver's seat 1 adjusted / changed due to the difference in the physique of the seated passenger. Regardless, a predetermined irradiation angle is set and maintained at the same position so that the driver's seat 1 (seat pan 8) can irradiate the area from the chest of the occupant to the thigh.

  As shown in FIGS. 5 and 6, when a side collision load P acts on the driver's seat 1 (seat pan 8), the driver's seat 1 (seat pan 8) moves to the console box 3 side. The living body detection sensor 4 is allowed to move in the vehicle width direction with respect to the driver's seat 1 (seat pan 8) by the pair of long connecting members 12 of the sensor support member 5.

  Thereby, when the driver's seat 1 (seat pan 8) moves in the width direction of the vehicle (the center side of the vehicle), the pair of long connecting members 12, the rear side surfaces of the console box 3 and the guide guide members 11 are vertically arranged. The driver's seat 1 (seat pan 8) moves in a state where the position of the living body detection sensor 4 with respect to the console box 3 does not change due to the wall surface. When the driver's seat 1 (seat pan 8) moves to the center side (passenger seat 2) of the vehicle, the distal end portion 12a of the long connecting member 12 contacts the restriction wall member 14 and bends downward. .

  Thereby, when the driver's seat 1 (seat pan 8) moves in the vehicle width direction (vehicle center side), the position of the living body detection sensor 4 with respect to the console box 3 remains unchanged. Pan 8) will move. When the driver's seat 1 (seat pan 8) moves to the center side (passenger seat 2) of the vehicle, the distal end portion 12a of the long connecting member 12 contacts the restriction wall member 14 and bends downward. .

  For this reason, even if the driver's seat 1 (seat pan 8) moves to the center side due to a side collision or the like, the absolute position of the living body detection sensor 4 with respect to the vehicle (console box 3) does not change. The irradiation range X of the electromagnetic wave does not change, and the vital sign of the occupant can be detected more appropriately. And the curved front-end | tip part 12a of the elongate connection member 12 contact | abuts to the control wall material 14, and it bends below, the movement to the center part side of the elongate connection member 12 is controlled, and the elongate connection member 12 is controlled. Is prevented from entering the passenger seat 2 side.

  Therefore, in the vehicle seat structure provided with the living body detection sensor 4 for detecting the vital sign of the occupant, the vital sign of the occupant is more appropriately detected even when the driver's seat 1 is moved due to a side collision or the like. It becomes possible.

A second embodiment of the sensor support member will be described with reference to FIGS.
FIG. 7 shows the situation of the main part of the seat structure for a vehicle according to the second embodiment of the present invention. FIG. 7 (a) shows a state where the seat pan is viewed from above, and FIG. It is a VII-VII line arrow view in 7 (a). Further, FIG. 8 shows a state in which the seat at the time of a side collision moves to the center side of the vehicle as viewed from the upper surface of the seat pan. The same members as those in the first embodiment shown in FIGS. 1 to 6 are denoted by the same reference numerals.

The sensor support member 21 is composed of a pair of long stretchable connecting members 22 fixed to the driver seat 1. A base end portion of a pair of long stretchable connecting members 22 is fixed to the side surface portion of the seat pan 8 of the driver's seat 1 that faces the console box 3 on the passenger compartment side so as to be orthogonal to the side surface portions. The members 22 are arranged in parallel at a predetermined interval. The long telescopic connecting member 22 is formed by projecting and urging a nesting composed of a plurality of cylindrical members having different diameters, and nesting the plurality of cylindrical members. And the side part of the console box 3 is set so as to correspond to the movement amount of the long expansion / contraction connection member 22 according to the front / rear slide amount of the seat slide position, and the long expansion / contraction connection member 22 is an opening of the side part of the console box 3. The living body detection sensor 4 is attached to the tips of the pair of long stretchable connecting members 22 through the console box 3.

  As shown in FIG. 7 (b), the shaft portion 13 a of the fixed portion 13 of the living body detection sensor 4 is arranged between the pair of long stretchable connection members 22, and a pair of long stretchable connection portions are provided on the lower surface of the living body detection sensor 4. The distal end of the member 22 (the smallest diameter cylindrical member) is attached, and the distal ends of the pair of long stretchable connecting members 22 are held by the retaining portion 13b. Thereby, the living body detection sensor 4 is supported movably in the longitudinal direction of the long expansion / contraction connection member 22 by the expansion / contraction movement of the pair of long expansion / contraction connection members 22, and the rotation of the biological detection sensor 4 is restricted.

  When the driver's seat 1 (seat pan 8) moves back and forth, the living body detection sensor 4 is guided by the guide guide member 11 of the console box 3 and moves forward and backward along with the pair of long telescopic connection members 22. For this reason, the electromagnetic wave irradiation range of the living body detection sensor 4 is maintained at the same position with respect to the driver seat 1 (seat pan 8) regardless of the position of the driver seat 1 in the front-rear direction.

  As shown in FIG. 8, when a side collision load P is applied to the driver's seat 1 (seat pan 8), the driver's seat 1 (seat pan 8) moves to the console box 3 side. The living body detection sensor 4 is contracted by a pair of long stretchable connection members 22 of the sensor support member 21 in contact with the guide guide member 11 and the long stretchable connection member 22 (nested shape) configured in a nested state. The driver seat 1 (seat pan 8) is allowed to move in the width direction of the vehicle.

  Thereby, when the driver's seat 1 (seat pan 8) moves in the width direction of the vehicle (the center side of the vehicle), the console box is formed by the telescopic long wall member 22 and the guide wall 11 of the guide guide member 11. Thus, the driver's seat 1 (seat pan 8) moves in a state where the position of the living body detection sensor 4 with respect to 3 does not change.

  For this reason, even if the driver's seat 1 (seat pan 8) moves to the center side due to a side collision or the like, the absolute position of the living body detection sensor 4 with respect to the vehicle (console box 3) does not change. The irradiation range of the electromagnetic wave does not change, and the vital sign of the occupant can be detected appropriately. And since the living body detection sensor 4 moves relatively with respect to the driver's seat 1 (seat pan 8) by expansion / contraction of the long expansion / contraction connecting member 22, there is no member that moves toward the center of the vehicle, and driving Even if the seat 1 moves to the center of the vehicle, other members do not enter the opposite side of the seat.

FIG. 10 shows a state in which the seat at the time of a side collision has moved to the center of the vehicle as viewed from the upper surface of the seat pan. The same members as those in the first embodiment shown in FIGS. 1 to 6 are denoted by the same reference numerals.

  As shown in FIG. 9A, a sensor support member 31 extending toward the console box 3 is provided on the side of the driver's seat 1 (seat pan 8) on the console box 3 side. The sensor support member 31 includes a pair of long link members 32 that are supported by the driver's seat 1. The base end portions of the pair of long link members 32 are rotatably supported in the vehicle front-rear direction on the side surface portion of the seat pan 8 of the driver seat 1 that faces the console box 3 on the passenger compartment side. The front end of the length link member 32 is provided extending in the width direction of the vehicle. The side surface portion of the console box 3 is set so as to correspond to the moving amount of the long link member 32 according to the front / rear slide amount of the seat slide position and the opening / closing amount described later. The pair of long link members 32 are inserted into the console box 3 from the opening of the side surface portion of the console box 3, and the living body detection sensor 4 is attached to the pair of long link members 32 in the closed state.

  As shown in FIG. 9B, a support piece 33 is fixed to a portion of the seat pan 8 where the base ends of the pair of long link members 32 are supported, and the pair of long link members 32 are supported on the support piece 33. The base end portion is supported rotatably. The support piece 33 is provided with a coil spring member 34, and the coil spring member 34 urges the closing side (the side indicated by the arrow in the figure) to rotate so that the distal ends of the pair of long link members 32 approach each other. Has been. The living body detection sensor 4 is clamped between the pair of long link members 32 by the pair of long link members 32 being pivotally biased toward the closed side.

  As shown in FIG. 9, on the opposite side of the driver seat 1 of the guide guide member 11 of the console box 3, a regulating wall member 35 is provided upright from the bottom of the console box 3 along the guide guide member 11. . An inclined portion 36 that gradually narrows outward is formed at the distal ends of the pair of long link members 32, and the distal end of the inclined portion 36 is in contact with the regulating wall member 35 in a normal state (a state in which no side impact load is applied). It is in contact.

  The shaft portion 13a of the fixing portion 13 of the living body detection sensor 4 is sandwiched between the pair of long link members 32, and the removal prevention portion 13b prevents the removal. Thereby, rotation of the living body detection sensor 4 is regulated. The rotation of the living body detection sensor 4 can be restricted by providing a support plate material whose rotation position is restricted with respect to the guide guide member 11 of the console box 3 and fixing the living body detection sensor 4 to the support plate material. .

  When the driver's seat 1 (seat pan 8) moves back and forth, the shaft portion 13a of the fixing portion 13 of the living body detection sensor 4 is sandwiched between the pair of long link members 32, and is prevented from being detached by the retaining portion 13b. Since it is blocked, the living body detection sensor 4 is guided by the guide guide member 11 of the console box 3 and moves forward and backward with the pair of long link members 32. For this reason, the electromagnetic wave irradiation range of the living body detection sensor 4 is maintained at the same position with respect to the driver seat 1 (seat pan 8) regardless of the position of the driver seat 1 in the front-rear direction.

  As shown in FIG. 10, when a side collision load P is applied to the driver's seat 1 (seat pan 8), the driver's seat 1 (seat pan 8) moves to the console box 3 side. When the driver's seat 1 (seat pan 8) moves to the console box 3 side, the restricting member serves as a guide through the inclined portions 36 of the pair of long link members 32, whereby the urging force of the coil spring member 34 In contrast, the pair of long link members 32 are operated in the opening direction, and movement of the living body detection sensor 4 is allowed. Thereby, when the driver's seat 1 (seat pan 8) moves in the vehicle width direction (vehicle center side), the position of the living body detection sensor 4 with respect to the console box 3 remains unchanged. Pan 8) will move.

  For this reason, even if the driver's seat 1 (seat pan 8) moves to the center side or is deformed by movement due to a side collision or the like, the absolute position of the living body detection sensor 4 with respect to the vehicle (console box 3) changes. Without being changed, the irradiation range of the electromagnetic wave of the living body detection sensor 4 is not changed, and the vital sign of the occupant can be detected appropriately. And since a pair of long link member 32 contact | abuts to the regulation wall material 35 and is operated to an opening direction, the penetration | invasion to the sheet | seat side on the opposite side of the front-end | tip of a pair of long link member 32 is suppressed.

  The vehicle seat structure described above is a vehicle seat structure provided with the living body detection sensor 4 for detecting a vital sign of an occupant, even if the driver's seat 1 is moved due to a side collision or the like. Since the absolute position (radiation range of the electromagnetic wave) of the living body detection sensor 4 with respect to the box 3) does not change, it becomes possible to detect the occupant's vital sign more appropriately.

  The embodiments described above are merely examples and do not exclude application of various modifications and techniques. In addition, each configuration of this example can be implemented with various modifications without departing from the spirit, and can be selected and combined as appropriate. For example, in each of the above embodiments, the console box is used as the vehicle body constituent member. However, the present invention may be used for another vehicle body constituent member in a vehicle in which the console box does not exist.

  INDUSTRIAL APPLICABILITY The present invention can be used in the industrial field of a vehicle seat structure provided with a living body detection sensor that detects a vital sign of an occupant.
