  As a result, when the occupant gets out of the vehicle, the entire vehicle seat takes a posture suitable for getting out of the vehicle body, and the dismountability is further improved.

  As described above, the vehicle seat according to the present invention has an excellent effect of being able to take a posture suitable for getting off when getting off.

  A vehicle seat 10 according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 3. An arrow FR and an arrow UP that are appropriately described in each figure indicate the forward direction (traveling direction) and the upward direction of the automobile S to which the vehicle seat 10 is applied, respectively.

  FIG. 1 shows a schematic overall configuration of the vehicle seat 10 in a side view. As shown in this figure, a vehicle seat 10 is a front seat for a passenger to get on and off from a vehicle body opening O located in front of a center pillar P that is a vehicle body skeleton (driver seat in this embodiment). And includes a seat cushion 12 on which an occupant of the automobile is seated and a seat back 14 that supports the upper body of the seated occupant from behind. The seat cushion 12 is mounted on an electric seat slider 16 as a power seat slide device provided on the vehicle body floor F, and is moved forward and backward within a predetermined range with respect to the vehicle body floor F by the operation of the electric seat slider 16. It slides in the direction (relative displacement).

  The electric seat slider 16 operates so that the seat cushion 12 (that is, the vehicle seat 10) slides back and forth according to the operation direction when the seated passenger of the vehicle seat 10 operates the hand switch, and gets off as described later. The seat cushion 12 is sometimes actuated to retract. In addition, about the mechanical structure of the electrically driven seat slider 16, since well-known various structures can be taken, description is abbreviate | omitted.

  The seat back 14 has a lower end portion 14A connected to the rear end portion 12A of the seat cushion 12 via an electric recliner 18 as a power type reclining device. The seat back 14 is configured to change (adjust) the inclination angle with respect to the seat cushion 12 by the operation of the electric recliner 18.

  The electric recliner 18 operates to cause the seat back 14 to be tilted or tilted backward with respect to the seat cushion 12 according to the operation direction when a seated occupant of the vehicle seat 10 operates a hand switch. The tilt angle (rear tilt angle) with respect to the seat cushion 12 is configured to operate so as to decrease (cause the seat back 14). In addition, about the mechanical structure of the electric recliner 18, since well-known various structures can be taken, description is abbreviate | omitted.

  The vehicle seat 10 described above is controlled by a seat ECU 20 as a control device. The seat ECU 20 is electrically connected to a slide position sensor 22 that outputs a signal according to the front-rear position of the seat cushion 12 with respect to the vehicle body floor F, and a reclining position sensor 24 that outputs a signal according to an inclination angle of the seat back 14 with respect to the seat cushion 12. The output signals of these sensors 22 and 24 are inputted.

  The slide position sensor 22 is, for example, a sensor that outputs a signal corresponding to the sliding direction and the sliding amount of the seat cushion 12 with respect to the reference position. For example, a magnetic sensor using a Hall IC or an electric motor constituting the electric seat slider 16 is used. A rotation sensor or the like that detects a rotation position or a pulse can be used. Therefore, the slide position sensor 22 is configured to be able to detect the current position with respect to the reference position of the seat cushion 12. The reclining position sensor 24 may be a rotary encoder or a rotation sensor that detects a rotation position or pulse of an electric motor that constitutes the electric recliner 18.

  The seat ECU 20 includes, for example, an ignition switch (not shown), a door lock switch that outputs a signal according to the lock or release of the door lock, a door knob switch that outputs a signal according to an operation of a door knob (door handle), and a seat belt device. Is electrically connected to a part or all of a buckle switch or the like that outputs a signal corresponding to whether or not the tongue plate is attached to the buckle device that constitutes the vehicle. Based on the output signals of these switches (sensors), the vehicle The seat 10 is configured to determine whether or not the seated occupant intends to get off. Since various known methods can be adopted as a method for determining whether a seated occupant of the vehicle seat 10 intends to get off, a description thereof will be omitted.

  When the seat ECU 20 determines that the seated occupant of the vehicle seat 10 intends to get off based on signals from the various switches (for example, a door open signal), an imaginary line and an arrow A in FIG. As described above, the electric seat slider 16 is operated to retract the seat cushion 12 (that is, the vehicle seat 10). Specifically, the seat ECU 20 moves the seat cushion 12 backward by a predetermined amount based on the output signal of the slide position sensor 22 from the front-rear position (hereinafter referred to as “use position”) of the seat cushion 12 while riding with respect to the vehicle body floor F. It is like that. Thereby, in the automobile S to which the vehicle seat 10 is applied, the space for removing the occupant's feet is increased when the passenger gets off.

  The predetermined amount by which the seat cushion 12 is retracted may be constant regardless of the use position, and changes depending on the position of the seat cushion 12 during the ride (for example, the use position is rearward (corresponding to the riding of a large passenger). It is also possible to increase the reverse amount). When the seat ECU 20 determines that the seat cushion 12 has reached (or has reached) the rearward movement limit of the electric seat slider 16 based on the output signal of the slide position sensor 22 (or the detection signal of the limit switch). Thus, even when the retracting amount of the seat cushion 12 does not reach the predetermined amount, the operation of the electric seat slider 16 is stopped.

  In addition, the seat ECU 20 is configured such that the seat cushion 12 is retracted or the retracted target (predicted) position (an output signal of the slide position sensor 22 or a control signal to the slide position sensor 22 or the like) at the time of getting off, and the seat cushion of the seat back 14. 2, when it is determined that the front surface 14B of the seat back 14 overlaps the center pillar P in the longitudinal direction of the vehicle body based on the inclination angle (output signal of the reclining position sensor 24) with respect to 12, as shown in FIG. The electric recliner 18 is actuated to cause the seat back 14. The phantom line in FIG. 1 shows the seat back 14 after this has occurred.

  Specifically, the seat ECU 20 is configured to cause the seat back 14 so that the front surface 14B (at least a part thereof) of the seat back 14 is positioned in front of the center pillar P. As a result, in the automobile S to which the vehicle seat 10 is applied, the center pillar P is not located on the side of the occupant who is about to get off, in other words, the seat back 14 is retracted to a position where it overlaps the center pillar P. Even in this case, an exit route that avoids the center pillar P is formed for the seated occupant of the vehicle seat 10.

  Furthermore, the seat ECU 20 maintains the front and rear positions of the seat cushion 12 and the inclination angle of the seat back 14 with respect to the seat cushion 12 when getting off, and secures a passenger's boarding space for the next boarding. Then, for example, when a door close signal is input, the seat ECU 20 slides (forwards) the seat cushion 12 to the stored riding position and tilts the seat back 14 backward to the stored inclination angle. It is configured.

  Next, the operation of the first embodiment will be described with reference to the flowchart shown in FIG.

  In the vehicle seat 10 having the above-described configuration, the seat ECU 20 determines whether or not the occupant intends to get off at step S10 based on, for example, whether or not a door opening / closing signal is input. If it is determined that there is no intention to get off, the process returns to step S10 and is repeated until the intention to get off is confirmed. On the other hand, the seat ECU 20 confirming the intention to get off at step S10 proceeds to step S12, and operates the electric seat slider 16 to retract the seat cushion 12, that is, the vehicle seat 10 by a predetermined amount.

  Next, the seat ECU 20 proceeds to step S14, and based on the output signal of the slide position sensor 22 (front and rear position information of the seat cushion 12) and the output signal of the reclining position sensor 24 (inclination angle information of the seat back 14), the vehicle seat. It is determined whether or not the center pillar P is located on the exit route of the ten seated passengers. When it is determined that the center pillar P does not exist in the getting-off route, the seat ECU 20 ends the control as it is.

  On the other hand, the seat ECU 20 that has determined that the center pillar P is located in the exit path of the seated occupant of the vehicle seat 10 in step S14 operates the electric recliner 18 so that the front surface 14B of the seat back 14 is in front of the center pillar P. The seat back 14 is caused to be positioned at the position, and then the control is terminated.

  Here, in the automobile S provided with the vehicle seat 10, the seat cushion 12 is retracted when the occupant seated in the vehicle seat 10 gets off, so that the foot space for the occupant is expanded and the dismounting property is improved. When the seat cushion 12 is moved backward as described above, the center pillar P in which the front surface 14B of the seat back 14 overlaps the center pillar P in the longitudinal direction of the vehicle body as in the comparative example seat 100 shown in FIG. There is a concern that the occupant's getting-off route may be blocked (the hatched portion H of the center pillar P projects over the getting-off route). However, in the vehicle seat 10, when the center pillar P is located on the getting-off route, the seat back 14 can be formed (switched) so as to get off the route without the center pillar P, while securing the above-mentioned underfoot space.

  Thus, in the vehicle seat 10 according to the first embodiment, when the seated occupant gets out of the vehicle seat, the posture is suitable for getting off and the dismounting property is improved.

  Further, in the vehicle seat 10, the seat back 14 is raised in accordance with the occupant's dismounting operation (rotates in the direction of the arrow B), thereby supporting the occupant's center of gravity movement operation (the driving force of the electric recliner 18 is It can be given as an alighting assistance force). Thereby, the getting-off operation of the seated occupant of the vehicle seat 10 becomes easier.

  Further, in the automobile S to which the vehicle seat 10 is applied and includes the rear seat 26 as shown in FIG. 2, the seat cushion 12 is retracted as described above by causing the seat back 14 (see the solid line). In some cases, the seat back 14 is prevented or suppressed from narrowing the knee space of the rear seat (see imaginary line). Thereby, in the motor vehicle S in which the vehicle seat 10 is applied to the front seat, it is possible to improve the boarding / alighting ability of the front seat occupant without sacrificing the boarding / alighting performance of the rear seat occupant.

  In the first embodiment, the example in which it is determined whether the center pillar P is located on the getting-off route based on the output signals of the slide position sensor 22 and the reclining position sensor 24 has been described. For example, it is assumed that the inclination angle of the seat back 14 is within a predetermined range, and it is determined whether or not the center pillar P is located on the getting-off route based only on the output signal of the slide position sensor 22. May be. In addition, for example, instead of the slide position sensor 22, a switch that outputs an ON signal when the seat cushion 12 is located behind a predetermined position is provided, and when the switch outputs an ON signal, a predetermined angle set in advance is provided. It is good also as a structure controlled so that the seat back 14 may be caused.

  Next, another embodiment of the present invention will be described. Note that parts and portions that are basically the same as those in the first embodiment or the previous configuration are denoted by the same reference numerals as those in the first embodiment or the previous configuration, and description thereof is omitted. Illustration may be omitted.

(Second Embodiment)
FIG. 4 is a schematic side view showing a vehicle seat 30 according to the second embodiment of the present invention. As shown in this figure, the seat ECU 32 constituting the vehicle seat 30 is electrically connected to a center pillar sensor 34 as an overlap detector in place of the reclining position sensor 24. It differs from the vehicle seat 10 according to the embodiment. FIG. 4 shows a state in which the seat cushion 12 is retracted by a predetermined amount when getting off the vehicle.

  The center pillar sensor 34 is, for example, a magnetic sensor in which a detection unit is provided in the seat back 14 and a detection unit is provided in the center pillar P, and the seat back 14 has a predetermined posture with respect to the center pillar P. It is configured (arranged) to output an ON signal when it is taken and to output an OFF signal in other cases. In this embodiment, the center pillar sensor 34 outputs an OFF signal when the front surface 14B of the seat back 14 overlaps the center pillar P in the front-rear direction as shown by a solid line in FIG. As shown in the drawing, the arrangement of the detection unit and the detected unit is set so that the front signal 14B of the seat back 14 outputs an ON signal at a position where the front surface 14B protrudes forward of the center pillar P.

  In this embodiment, the position of the seat cushion 12 after retreating at the time of getting off is fixed regardless of the use position, or the difference due to the use position is small (the seat back in the assumed inclination angle range). 14 is located within the detection range of the center pillar sensor 34). The seat ECU 32 is configured to operate the electric recliner 18 in the direction in which the seat back 14 is raised until the ON signal is input from the center pillar sensor 34 when the seat cushion 12 is retracted when the vehicle gets off. Yes. Other configurations of the vehicle seat 30 are the same as the corresponding configurations of the vehicle seat 10.

  Next, the operation of the second embodiment will be described with reference to the flowchart shown in FIG.

  In the vehicle seat 30 having the above-described configuration, the seat ECU 32 determines whether or not the occupant intends to get off at step S10 based on, for example, whether or not a door opening / closing signal is input. If it is determined that there is no intention to get off, the process returns to step S10 and is repeated until the intention to get off is confirmed. On the other hand, the seat ECU 32 confirming the intention to get off at step S10 proceeds to step S12, and operates the electric seat slider 16 to retract the seat cushion 12, that is, the vehicle seat 10 by a predetermined amount.

  Next, the seat ECU 32 proceeds to step S20, and determines whether or not the output signal of the center pillar sensor 34 is an ON signal. If the center pillar sensor 34 is outputting an ON signal, the electric recliner 18 is stopped in step S22 (if the electric recliner 18 is not operated), the control is terminated. On the other hand, the seat ECU 32 that determines that the center pillar sensor 34 does not output the ON signal in step S20 proceeds to step S24, operates the electric recliner 18, and returns to step S20. That is, the electric recliner 18 continues to operate in the direction in which the seat back 14 is raised until the center pillar sensor 34 outputs an ON signal, thereby causing the seat back 14. When the center pillar sensor 34 outputs an ON signal, the seat ECU 32 stops the electric recliner 18 in step S22 and ends the control.

  As described above, the vehicle seat 30 according to the second embodiment is different from the first embodiment only in the method for determining whether or not the center pillar P is present on the getting-off route. As a result, the same effect as in the first embodiment can be obtained.

(Third embodiment)
FIG. 6 is a schematic side view showing a vehicle seat 40 according to the third embodiment of the present invention. As shown in this figure, the seat ECU 42 constituting the vehicle seat 40 is electrically connected to an obstacle sensor 44 as an obstacle detector instead of the reclining position sensor 24 and the center pillar sensor 34. Thus, the vehicle seat 10 and the vehicle seat 30 according to the first or second embodiment are different. FIG. 6 shows a state in which the seat cushion 12 is retracted by a predetermined amount when getting off.

  The obstacle sensor 44 is, for example, an optical sensor and is attached to the upper portion of the seat back 14, and an object (an obstacle that reflects light) is present within a predetermined range from the outer side in the width direction to the front of the part. In this case, an ON signal is output. In other words, the seat ECU 42 can determine whether the center pillar P or an obstacle other than the center pillar P exists based on the output signal of the obstacle sensor 44.

  When the obstacle sensor 44 outputs an ON signal after the seat cushion 12 is retracted when the vehicle gets off, the seat ECU 42 tilts until the output signal of the obstacle sensor 44 is switched to the OFF signal or the inclination angle of the seat back 14. Is configured to operate the electric recliner 18 in the direction in which the seat back 14 is raised until a predetermined inclination angle (for example, an angle standing upright with respect to the seat cushion 12) is reached. Other configurations of the vehicle seat 30 are the same as the corresponding configurations of the vehicle seat 10.

  In the vehicle seat 40 according to the third embodiment, the seat ECU 42 determines whether or not the signal of the obstacle sensor 44 is an ON signal when the seat cushion 12 is retracted when the vehicle gets off. When the obstacle sensor 44 outputs an ON signal, that is, when there is an obstacle on the getting-off route, the seat ECU 42 operates the electric recliner 18 to cause the seat back 14. When the output signal of the obstacle sensor 44 is switched to the OFF signal before the inclination angle of the seat back 14 reaches the predetermined inclination angle, or when the inclination angle of the seat back 14 reaches the predetermined inclination angle. The seat ECU 42 stops the operation of the electric recliner 18. As a result, an exit route in which no obstacle exists for the seated occupant of the vehicle seat 40 is formed, or an exit route that is suppressed from being narrowed by the obstacle is formed.

  That is, the vehicle seat 40 according to the third embodiment can basically obtain the same effect by the same operation as that of the first embodiment. Further, in the vehicle seat 40, obstacles other than the center pillar P can be detected by the obstacle sensor 44, and the obstacles can be prevented from being positioned on the getting-off route. For example, even when the center pillar P is not positioned on the getting-off path in a posture in which the seat cushion 12 is retracted when getting off, it is assumed that a part of the luggage protrudes forward from the center pillar P, that is, on the getting-off path. In such a case (in the case where the control for causing the seat back 14 is not performed in the first embodiment), it is possible to cause the seat back 14 to form an exit route in which no obstacle exists (or the amount of protrusion is small).

  In each of the above embodiments, an example in which the seatback 14 is caused when an obstacle such as the center pillar P is present on the getting-off route is shown. However, the present invention is not limited to this example. Regardless of whether or not P or the like is positioned, or when the seat cushion 12 is retracted to a position where the center pillar P is present in the getting-off path, the seat is always taken when the seated occupant of the vehicle seat 10, 30, 40 gets off. You may make it control so that the back | bag 14 may be caused.

  Further, in each of the above embodiments, an example has been shown in which the seat cushion 12 is automatically retracted to cause the seat back 14 when getting off, but the present invention is not limited to this. For example, the seat cushion 12 is manually retracted. In this case, the seat back 14 may be caused, or only the control for causing the seat back 14 may be performed for assisting the movement of the center of gravity of the seated occupant in the configuration in which the seat cushion 12 is not retracted.
