  By the way, at the time of a side collision of the vehicle, for example, as shown in FIG. 4, the inertial force Fi toward the collision side seat 3L with respect to the occupant PD of the opposite side seat 3R across the collision side seat 3L and the center console 2 is sandwiched. Will act. However, in the shoulder belt portion 41R of the seat belt device 4R, the movement of the occupant PD in the forward direction of the vehicle 1 can be restricted due to its structure, but the occupant PD toward the seat 3L on the collision side is limited. Since the movement cannot be restricted accurately, the passenger PD may pass through the shoulder belt portion 41R and move largely toward the collision side seat 3L. In this case, there is a risk of contact with the occupant of the collision side seat 3L and the door trim 11L deformed by the collision, and the occupant PD cannot be protected accurately.

  In addition, as an apparatus which suppresses a passenger | crew's side movement at the time of the side collision of a vehicle, there exists a passenger | crew protection device of the vehicle described in patent document 1 and patent document 2, for example. In conventional general occupant protection devices including those described in Patent Document 1 and Patent Document 2, an airbag is housed inside a console box provided at the top of the center console, and at the time of a side collision of the vehicle, By inflating and deploying the airbag from the inside of the console box to the outside and the outside, an occupant trying to fall down to the center console side is protected. However, in such an occupant protection device for a vehicle, since the airbag is only fixed to the vehicle by its base end portion, when the occupant tries to fall to the console side, the airbag falls with the occupant. End up. For this reason, a passenger | crew cannot fully be supported and a passenger | crew cannot be protected appropriately.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a vehicle occupant protection device capable of suppressing the occupant from largely moving to the side during a side collision of the vehicle. is there.

Hereinafter, means for solving the above-described problems and the effects thereof will be described.
According to the first aspect of the present invention, the vehicle occupant protection device is disposed so as to extend in the front-rear direction of the vehicle in the passenger compartment, and the occupant sits on the center console whose upper surface is located above the vehicle floor The gist of the invention is to provide a moving mechanism for moving the seat to be relatively moved so as to suppress movement of the occupant in the vehicle width direction at the time of a side collision of the vehicle.

  According to this configuration, in the event of a side collision of the vehicle, that is, when a force that causes the occupant to fall toward the center console acts, the center console is configured to suppress the movement of the occupant in the vehicle width direction. Since the seat and the seat move relative to each other, the occupant is supported by the center console. For this reason, it can suppress that a passenger | crew moves largely in the vehicle width direction at the time of the side collision of a vehicle.

  The gist of the invention described in claim 2 is that, in the vehicle occupant protection device according to claim 1, the moving mechanism moves the center console upward during a side collision of the vehicle.

  According to this configuration, the center console moves to a higher position in the event of a side collision of the vehicle than in the non-collision, so that the force that causes the occupant to fall down to the center console side acts upward from the waist. This part can be widely supported by the side surface of the center console, and the occupant can be prevented from largely moving to the side.

  More specifically, according to the invention described in claim 3, the center console has a console box having an accommodation space inside, and the moving mechanism is the console box of the center console. It is possible to adopt a configuration in which the is moved upward.

  Here, by making the relative position of the center console higher with respect to the seat on which the occupant is seated, it is possible to surely suppress the occupant from largely moving to the side. However, if the center console becomes excessively high with respect to the seat, a relatively weak portion such as an occupant's chest may collide with the side surface of the center console.

  In this regard, according to the fourth aspect of the present invention, the vertical distance between the center position in the front-rear direction of the vehicle on the upper surface of the seat portion of the seat and the hip point of the occupant conforming to the ISO 6549-1999 standard is H1. When the distance in the vertical direction between the center position and the upper surface of the center console is H2, the moving mechanism relatively moves the seat and the center console within a range satisfying the relationship of H2 / H1 ≦ 6.0. If this is done, it is possible to suppress the occurrence of the above-described problems associated with the position of the center console being relatively high with respect to the seat.

  According to a fifth aspect of the present invention, in the vehicle occupant protection device according to any one of the first to fourth aspects, the moving mechanism moves the center console forward of the vehicle in a side collision of the vehicle. The gist.

  According to this configuration, in the event of a side collision of the vehicle, the center console moves further forward than in the non-collision, so that the front side of the occupant's body can be supported by the side of the center console. Large lateral movement can be suppressed.

  Here, by supporting the front portion of the occupant's body by the side of the center console, it is possible to surely prevent the occupant from moving largely to the side. However, when the center console supports most of the occupant's body, which is closer to the front, the rotation of the body around the occupant's upper body will be suppressed, and the occupant's head will change to the side. There is a risk of moving to

  In this regard, as in the sixth aspect of the invention, the horizontal distance between the occupant's hip point conforming to the ISO 6549-1999 standard and the center position in the front-rear direction of the vehicle on the upper surface of the seat portion of the seat is L1. When the horizontal distance between the hip point and the end surface of the center console in the vehicle front direction is L2, the moving mechanism moves the center console within a range satisfying the relationship of L2 / L1 ≦ 1.6. Such a configuration can be adopted. If the range of movement of the center console to the front of the vehicle is set in this way, the above-mentioned problems associated with the center console supporting most of the occupant's body closer to the front will also occur. This can be suppressed.

  According to the seventh aspect of the present invention, if the moving mechanism moves the center console and the seat relative to each other when a side collision of the vehicle is predicted, Prior to falling down, the center console and the seat can be moved relative to each other at appropriate timing.

  It is possible to prevent the occupant from moving greatly to the side during a side collision of the vehicle.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which a vehicle occupant protection device according to the present invention is applied to a side collision occupant protection device provided on the front side of a passenger compartment will be described below with reference to FIGS. In this embodiment, since the same configuration as the seat 3 shown in FIG. 3 is adopted as the configuration of the seat provided in the vehicle width direction of the center console, the same reference numeral is used here for explanation. Omit. Further, in this embodiment, it is assumed that the seat 3 does not move specially at the time of a side collision of the vehicle.

  Fig.1 (a) is the side view which showed typically the state of the passenger | crew protection device at the time of non-collision. Moreover, FIG.1 (b) is the side view which showed typically the state of the passenger | crew protection device at the time of a collision.

  As shown in FIG. 1A, a rail 51 is provided on the floor 10 in the passenger compartment so as to extend in the front-rear direction of the vehicle. A console 20 is provided. The center console 20 includes a console body 21 having a substantially rectangular parallelepiped shape and a console box 22 having a substantially rectangular parallelepiped shape housed in the console body 21. The console box 22 is located in the upper part of the center console 20, and an accommodation space is formed therein. A roller 52 that moves along the rail 51 and a motor 53 for driving the roller 52 are provided at the lower portion of the console body 21. In this embodiment, the rail 51, the roller 52, and the motor 53 constitute the first moving mechanism 5 that moves the center console 20 forward of the vehicle.

  In addition, a second moving mechanism 6 for moving the console box 22 upward is provided below the console box 22 inside the console main body 21. The moving mechanism 6 includes a cylinder 61 disposed so that the longitudinal direction thereof is the vertical direction, and a rod 62 that is accommodated in the cylinder 61 and movable upward, and is filled in the cylinder 61. By igniting the generated gas, the rod 62 is pushed upward by utilizing the expansion energy.

  Further, the vehicle is provided with a collision prediction device for predicting the collision of the vehicle. When the vehicle is predicted to collide through the collision prediction device, the first moving mechanism 5 is based on the collision prediction signal. Is driven, and the rod 62 constituting the second moving mechanism 6 is pushed upward. As a result, as shown in FIG. 1B, the center console 20 moves forward of the vehicle and the console box 22 moves upward of the vehicle.

FIG. 2 is a side view showing the positional relationship between the center console 20, the driver's seat 3 positioned in the vehicle width direction of the center console 20, and the occupant PD seated on the seat 3.
Next, the allowable range of upward movement of the console box 22 will be described with reference to FIG.

  As shown in FIG. 2, the center position in the front-rear direction of the vehicle on the upper surface of the seat 31 of the seat 3 is defined as a position CS. Further, the hip point of the occupant PD conforming to the ISO 6549-1999 standard is set as the position HP. The vertical distance between the position CS and the position HP is H1, and the vertical distance between the position CS and the upper surface 22A of the console box 22 is H2. At this time, in this embodiment, the console box 22 is moved upward within a range satisfying the expression (1).

H2 / H1 ≦ 6.0 (Expression 1)
Here, when H2 / H1 = 6, the upper surface 22A of the console box 22 is positioned slightly below the chest of the occupant PD.

Next, the allowable movement range of the center console 20 to the front of the vehicle will be described with reference to FIG.
As shown in FIG. 2, the horizontal distance between the position HP and the position CS is L1, and the horizontal distance between the position HP and the end surface 20b of the center console 20 in the vehicle front direction is L2. At this time, in this embodiment, the center console 20 is moved forward in the range satisfying the expression (2).

L2 / L1 ≦ 1.6 (Expression 2)
Here, at the time of a side collision of the vehicle, a force that rotates the lower half about the upper half of the body of the occupant PD often acts. Specifically, when the occupant's waist is supported by the center console 20, the knee portion tries to rotate with the support portion as a fulcrum. When such body rotation occurs, the upper body of the occupant is inclined in an oblique direction with respect to the vehicle width direction. The amount of movement in the vehicle width direction decreases.

  On the other hand, as the center console 20 moves to the front of the vehicle, a wider range of the front portion of the body of the occupant PD is supported by the center console 20. When L2 / L1> 1.6, most of the front part of the body of the occupant PD is supported by the center console 20. For this reason, the rotation of the body around the upper body of the occupant PD is excessively suppressed, and the amount of movement of the head of the occupant PD may increase. On the other hand, when L2 / L1 ≦ 1.6, the front portion of the body of the occupant PD is moderately supported by the center console 20. For this reason, the rotation of the body around the upper body of the occupant PD is not excessively suppressed, and an increase in the amount of movement of the head of the occupant PD can be suppressed.

According to the vehicle occupant protection device of this embodiment described above, the following effects can be obtained.
(1) In the event of a side collision of the vehicle, the second moving mechanism 6 moves the console box 22 of the center console 20 upward. As a result, at the time of a side collision of the vehicle, that is, when a force that causes the occupant PD to fall toward the center console 20 is applied, the center console 20 moves to a higher position than at the time of non-collision. For this reason, it is possible to widely support the upper part of the waist from the waist where a large force is applied to the occupant PD toward the center console 20 by the side surface of the center console 20, and at the time of a side collision of the vehicle, It is possible to suppress the occupant PD from largely moving to the side.

  (2) By making the relative position of the center console 20 with respect to the seat 3 on which the occupant PD is seated higher, it is possible to surely prevent the occupant PD from moving greatly to the side. However, if the center console 20 becomes excessively high with respect to the seat 3, there is a possibility that a relatively weak portion such as the chest of the occupant PD may collide with the side surface of the center console 20.

  In this regard, in the above embodiment, the vertical distance between the center position CS of the front and rear direction of the vehicle on the upper surface of the seat 31 of the seat 3 and the hip point HP of the occupant conforming to the ISO 6549-1999 standard is H1, and the center When the vertical distance between the position CS and the upper surface of the center console 20 is H2, the seat 3R and the center console 20 are moved within a range satisfying the relationship of H2 / H1 ≦ 6.0. As a result, it is possible to suppress the occurrence of the above-described problem associated with the position of the center console 20 being relatively high with respect to the seat 3.

  (3) In the event of a side collision of the vehicle, the first moving mechanism 5 moves the center console 20 forward of the vehicle. Thereby, at the time of a side collision of the vehicle, the center console 20 moves more forward than at the time of non-collision. For this reason, it can be supported by the side of center console 20 to the part near the front among occupant PD's bodies, and it can control that occupant PD greatly moves to the side.

  (4) By supporting the portion closer to the front of the body of the occupant PD by the side surface of the center console 20, it is possible to surely suppress the occupant PD from largely moving to the side. . However, when the center console 20 supports the most part of the body of the occupant PD closer to the front, the rotation of the body around the upper body of the occupant PD is suppressed, and the head of the occupant PD and the like However, there is a risk of moving to the side.

  In this regard, in the above embodiment, the horizontal distance between the occupant's hip point HP conforming to the ISO 6549-1999 standard and the center position CS in the front-rear direction of the vehicle on the upper surface of the seat 31 of the seat 3R is L1, and the hip When the distance in the horizontal direction between the point HP and the front end face 20b of the center console 20 is L2, the center console 20 is moved within a range satisfying the relationship of L2 / L1 ≦ 1.6. The occurrence of the above-described problem associated with the center console 20 supporting the most part of the body of the passenger PD closer to the front can also be suppressed.

  (5) The center console 20 is moved when a side collision of the vehicle is predicted. Accordingly, the center console 20 can be moved at an appropriate timing prior to the occupant PD falling down to the center console 20 side.

(Other embodiments)
Note that the vehicle occupant protection device according to the present invention is not limited to the configuration exemplified in the above embodiment, and can be implemented as, for example, the following forms appropriately modified.

  As in the above-described embodiment, when the collision is predicted, the console box 22 is moved upward and the center console 20 is moved forward of the vehicle before the passenger falls to the center console 20 side. It is desirable to move at a precise timing. However, for example, if a highly responsive moving mechanism can be used, the moving mechanism can be driven based on the fact that an actual collision has been detected.

  In the above embodiment, the configuration in which the console box 22 of the center console 20 is moved upward through the second moving mechanism 6 and the center console 20 is moved forward of the vehicle through the first moving mechanism 5 has been illustrated. However, the configuration of the moving mechanism for moving the center console 20 is not limited to these, and for example, the center console 20 is moved forward of the vehicle using the expansion energy of the gas as in the second moving mechanism. A moving mechanism may be employed, or a moving mechanism that moves the console box 22 upward using a motor may be employed. Of course, other moving mechanisms may be employed.

  -As in the above-described embodiment, moving the center console 20 forward of the vehicle is desirable in order to obtain an effect that the front side portion of the occupant's body is supported by the side surface of the center console 20. However, if the center console 20 has a sufficient length in the front-rear direction of the vehicle, the center console 20 is not moved forward, that is, only the console box 22 is moved upward. Can also achieve the above effects.

  In the above embodiment, the center console 20 has the console box 22 having an accommodation space inside, and the console box 22 alone of the center console 20 is moved upward through the second moving mechanism 6. However, the console body 21 may be moved upward together with the console box 22. Further, the center console is not limited to one having a console box, and may be one having no console box. In this case, the entire center console may be moved upward.

  In the above embodiment, only the center console of the center console and the seat is moved upward or forward of the vehicle. However, for example, the seat is moved downward while moving the center console upward. It may be. Alternatively, only the sheet may be moved downward without moving the center console. On the other hand, the seat may be moved rearward of the vehicle while moving the center console forward of the vehicle. Further, only the seat may be moved rearward of the vehicle without moving the center console.

  In short, the center console, which is disposed so as to extend in the vehicle front-rear direction in the passenger compartment and whose upper surface is located above the vehicle floor, and the seat on which the occupant sits, What is necessary is just to provide the moving mechanism to move relatively so that the movement to a direction may be suppressed.
