Description

  The present invention relates to a driving attitude control device that controls the attitude of a driver who is seated in a vehicle seat when the vehicle turns.

  In a turning operation of a vehicle such as an automobile, the driver often complains that the driving feeling (for example, ease of driving) differs between the left turn and the right turn even if the turning radius is the same. . As a result, for example, for any one of the left and right turns, there may be a difference in actual driving operation and vehicle behavior, such as an increase in the number of corrective rudder and a decrease in the steering speed.

  Here, as shown in FIG. 30, the driver 1 tilts the upper body toward the turning center in order to counter the inertial force and perform the steering operation when turning.

  However, when the inventors investigated the actual behavior of the upper body of the driver 1 during a turn, the tilt center 23 of the upper body tilt of the driver 1 is as shown in FIG. It has been found that the center line (trunk) CL is offset to either the left or right side (left side for the driver 1 in this example; right side in front view). The tilt center 23 of the tilt is a straight line extending in the direction perpendicular to the movement direction from the middle point of the left shoulder movement locus and the direction perpendicular to the movement direction from the middle point of the right shoulder movement locus. It was defined as the intersection with the stretched straight line.

By the way, what is disclosed by patent document 1 and 2 is known as an apparatus for protecting a passenger | crew.
Japanese Patent Laid-Open No. 2004-75015 JP 2003-335215 A

  And when the inventors repeated research on the offset of the tilt center of the upper body of the driver at the time of turning, in addition to the driver seat being offset from the vehicle center, the driver is a so-called three-point seat belt, etc. It was confirmed that one of the major factors was being restrained by the asymmetric seat belt.

  Therefore, the present invention reduces the amount of offset of the tilt center of the driver's upper body during turning when the driver is restrained to the seat by a laterally asymmetric seat belt, and turns left and right. The purpose is to reduce the difference in driving feeling.

  The driving posture control device according to the present invention is a driving posture control device that adjusts the posture of a driver who is constrained to a seat by a laterally asymmetric seat belt when the vehicle turns, and is a center line of the driver's body A contact mechanism that contacts the driver on the opposite side of the contact area with the shoulder or chest of the seat belt, and the contact surface pressure in the contact area with the driver of the contact mechanism The main feature is that it is higher than the contact surface pressure in the region.

  According to the present invention, the contact mechanism is brought into contact with the driver at a contact surface pressure higher than that of the seat belt on the opposite side of the contact area with the shoulder portion or the chest portion of the seat belt. The offset amount of the tilt center from the center line of the driver's upper body can be reduced, so that the difference in driving feeling between the left turn and the right turn can be reduced.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  (First Embodiment) FIG. 1 is a front view showing a state where a driver is seated on a seat, FIG. 2 is a perspective view of a driving posture control device according to the present embodiment, and FIG. 3 is a contact of the driving posture control device. FIG. 4 is a front view showing a contact mechanism of a driving posture control device, a contact region by a seat belt, and a contact surface pressure, and FIG. 5 is (a) a conventional method. FIG. 6B is a diagram showing the distribution of the tilt center of the driver's upper body during a turn in this embodiment. FIG. 6 shows the tilt of the driver's upper body during a turn in the conventional method and this embodiment. It is a graph which shows the average value of the distance of a center and the centerline of a driver | operator's upper body.

  The driver 1 is seated on a seat (seat; driver's seat) 5 installed on the floor surface 4 of the vehicle body 3 in the passenger compartment 2, and is restrained by the seat 5 by the seat belt 6 in this state. Yes.

  The seat belt 6 includes a shoulder belt 6a that spans from the upper shoulder portion of the driver 1 to the left or right of the driver 1 (right side for the driver 1 in the present embodiment; left side in front view) and the outer side of the waist on the other side. 1 is a belt that is horizontally asymmetrical in front view, and includes a lap belt 6b that is laid horizontally in front of one waist. The shoulder belt 6a is bridged between an anchor 8 provided above the pillar 7 and a tongue 10 inserted into a buckle 9 attached to the vehicle body 3 or the seat 5, and a lap belt 6b is connected to the tongue 10 and others. It is bridged between the fixed part 11 on the side. Further, the shoulder belt 6a is folded back by an anchor 8 and drawn into a belt winding mechanism 12 installed below the shoulder belt 6a.

  Here, in the present embodiment, the seat belt 6 is equipped with a contact mechanism 13 that touches the shoulder or chest of the driver 1 to give a tactile stimulus. That is, the contact mechanism 13 is configured to include a base portion 14 provided with a through hole 16 through which the shoulder belt 6 a is inserted, and a pad portion 15 attached to the base portion 14. Further, the pad portion 15 is configured to have an arm portion 17 and a protruding contact portion 18 provided at the tip of the arm portion 17 on the opposite side of the base portion 14, and the arm portion 17 is configured to have the base portion 14. From the center line CL of the upper body of the driver 1 to a region that is opposite to the left and right of the contact region with the shoulder or chest of the shoulder belt 6a, and the contact portion 18 contacts the driver 1 in the region. I try to let them. The pad portion 15 is preferably formed from an elastic material such as urethane sponge.

  In the present embodiment, a contact position setting mechanism 19 is provided so that the position where the contact portion 18 contacts the driver 1 can be set. Specifically, as the contact position setting mechanism 19, a washer 20 that is fastened to the pillar 7 together with the anchor 8, and a wire 21 that is installed between the washer 20 and the base portion 14 are provided. Accordingly, the position of the base portion 14, that is, the contact mechanism 13 along the shoulder belt 6 a can be set. The length of the wire 21 can be variably set, such as a spiral shape, and the contact area where the contact mechanism 13 contacts the driver 1 can be variably set according to the physique of the driver 1. Is preferred. Further, the mounting angle of the pad portion 15 (arm portion 17) with respect to the base portion 14 may be variably set.

  According to the above embodiment, the offset amount of the center of tilt of the upper body of the driver 1 from the center line CL of the upper body of the driver 1 can be reduced, so that the left turn and the right turn can be reduced. The difference in driving feeling can be reduced. The principle will be described with reference to FIGS.

  When the driver 1 is restrained by the seat 5 by the left-right asymmetric seat belt 6, the degree of freedom of movement of the upper body of the driver 1 differs between the left and right. For example, in the case of the present embodiment, the right side (left side in front view) of the upper body of the driver 1 is restrained by the shoulder belt 6a and hardly moves, whereas the left side (in front view) of the driver's upper body. The right) is a situation where you can move relatively freely. Such a left-right asymmetric restraint state contributes to the offset from the center line CL of the tilt center 23 of the upper body shown in FIG.

  As a result of intensive research, the inventors have given tactile stimulation to the shoulder or chest of the upper body of the driver 1 that is not constrained by the seat belt 6, so that the center line of the tilt center 23 can be obtained. It was discovered that the offset from the CL was reduced, and that the difference in driving sensation between the left turn and the right turn could be reduced.

  It can be said that this phenomenon is caused by causing the driver 1 to have a masking effect of contact feeling with the seat belt 6 by applying the tactile stimulus as described above. The masking effect means that, for example, in a situation where a part of the body is strongly squeezed, if the other part is squeezed, the feeling of pressure in the part that was previously squeezed is diminished (or disappears). . In the case of the present embodiment, as shown in FIG. 4, the shoulder belt 6a is stretched from the upper right shoulder portion of the driver 1 to the outer left waist portion, and mainly on the right side of the shoulder portion and the chest (center line). A region (contact region A1) on the right side of CL and on the left side in front view is in contact with the shoulder belt 6a. Therefore, the masking effect is produced by bringing the contact portion 18 of the contact mechanism 13 into contact with the region (contact region A2) on the left side of the shoulder or chest (left side of the center line CL; right side in front view). Can do. Even when the shoulder belt is bridged from above the left shoulder of the driver to the outside of the right waist, the same applies if a tactile stimulus is applied to the right shoulder or waist of the driver using the contact mechanism. The effect of can be obtained.

  In addition, the above phenomenon causes a phantom sensation effect of contact sensation for the contact sensation with the seat belt 6 and the haptic stimulus by giving the driver 1 the tactile stimulus as described above. It can be said that there is. The phantom sensation effect means that when a tactile stimulus is received at two separated points, it feels as if the tactile stimulus is received at an intermediate part between the two points. In the case of the present embodiment, as described above, since the region (contact region A1) on the right side of the shoulder and chest (right side of the center line CL; left side in front view) is in contact with the shoulder belt 6a, contact is made. The phantom sensation effect is achieved by bringing the contact portion 18 of the mechanism 13 into contact with the opposite side, that is, the region (contact region A2) on the left side of the shoulder or chest (left side of the center line CL; right side in front view). Can be generated. Even when the shoulder belt is bridged from above the left shoulder of the driver to the outside of the right waist, the same applies if a tactile stimulus is applied to the right shoulder or waist of the driver using the contact mechanism. The effect of can be obtained.

  And in order to acquire the above effect, like this embodiment, it is between the peak position (center of A2 of FIG. 4) and the contact area A1 by the seatbelt 6 where the contact surface pressure by the contact mechanism 13 peaks. In addition, a non-contact region in which the pressing force does not substantially act on the driver 1 from the contact mechanism 13 is provided, or the pressing force from the contact mechanism 13 to the driver 1 is low (that is, the contact surface pressure is low). It will be appreciated that it is preferred to have a pressure contact area.

  5 and 6 show that tactile stimulation is applied to the shoulder or chest of the upper body of the driver 1 that is not restrained by the seat belt 6 using the contact mechanism 13 according to the present embodiment. This shows the effect (experimental result). 5 and 6, when the contact mechanism 13 is provided, the separation distance d from the center line CL of the tilt center 23 is smaller than when the contact mechanism 13 is not provided, and the tilt center 23 is the center line CL. You can see that you are approaching the side. By doing so, it was verified that the difference in the sense of the driver 1 between the left turn and the right turn was reduced, and the difference in the driving operation and the vehicle behavior was reduced.

  Furthermore, according to the inventors' research, these phenomena are caused by the contact surface pressure P2 in the contact region A2 (area S2) of the contact mechanism 13 and the contact surface pressure P1 in the contact region A1 (area S1) of the seat belt 6 in particular. If the distance from the center line CL to the center of the contact areas A1 and A2 (center of gravity of the distributed load) is L1 and L2, P1 × L2 = P2 × L1. It has been found to be even more effective. By doing so, the driver 1 is given a sense as if the pressing by the seat belt 6 and the pressing by the contact mechanism 13 are balanced on the left and right. Further, from the viewpoint of symmetry of the contact position, the contact area A2 of the contact mechanism 13 may be set to a position that is substantially symmetrical with respect to at least a part of the contact area A1 of the seat belt 6 with respect to the center line CL. The above effects are even more effective. In addition, when it is set as P1 <P2 as mentioned above, there also exists an advantage that the contact mechanism 13 (the contact part 18) can be comprised more compactly.

  Moreover, according to this embodiment, since the contact position setting mechanism 19 which sets the contact position with the driver | operator 1 of the contact mechanism 13 was provided, according to the physique of the driver | operator 1, a contact position is set more appropriately. Will be able to.

  In addition, according to the present embodiment, since the protruding contact portion 18 is provided, a configuration in which the contact mechanism 13 applies tactile stimulation to the shoulder portion or the chest portion of the driver 1 can be configured relatively simply. In addition, the contact surface pressure can be adjusted relatively easily by the size, number, and curvature of the tip of the protrusion.

  Further, according to the present embodiment, since the contact mechanism 13 is held by the seat belt 6, the contact mechanism 13 can be configured more simply than the case where the contact mechanism 13 is provided in another part (for example, the seat 5). .

  (Second Embodiment) FIG. 7 is a front view showing a state where a driver is seated on a seat, and FIG. 8 is a perspective view of a vehicle interior including a seat belt equipped with a driving posture control device according to the present embodiment. 9 is a perspective view of the driving posture control device, FIG. 10 is a cross-sectional view of the contact mechanism of the driving posture control device (cross-sectional view along BB in FIG. 9), and FIG. 11 is a plan view showing the back side of the contact mechanism. FIG. 12 is a front view showing a state where the driver is seated on the seat when the anchor is set at a higher position, and FIG. 13 is a case where the driver is seated on the seat when the anchor is set at a lower position. It is a front view which shows a state. In this embodiment, the same components as those in the first embodiment are included. Therefore, the same reference numerals are given to these components, and redundant description is omitted below.

  The contact mechanism 13A according to the present embodiment can be used in place of the contact mechanism 13 according to the first embodiment.

  However, in this embodiment, the contact mechanism 13A is provided with a plurality (two in this embodiment) of base portions 14Aa and 14Ab provided with through holes 16 through which the shoulder belt 6a is inserted, and the contact mechanism 13A is provided on the shoulder belt 6a. To be supported more stably.

  In the present embodiment, the tip of the arm portion 17A of the pad portion 15A is bent in a substantially L shape when viewed from the front, and a plurality (two in this embodiment) of contact portions 18Aa and 18Ab are provided in the bent portion. ing. These contact portions 18Aa and 18Ab are attached to the seat belt 6 (shoulder belt 6a), and the tilt angle direction of the shoulder belt 6a centered on the tongue 10 accompanying the vertical movement of the anchor 8 (the arc shape in FIG. 13). (Directions of arrows) are arranged so as to be shifted from each other. By doing so, as shown in FIGS. 12 and 13, regardless of the anchor 8 fixing position (up and down position), one of the two contact portions 18Aa and 18Ab can be subjected to the masking effect or the phantom sensation effect. It becomes possible to contact a more suitable area. Furthermore, in this case, the angle of the arrangement direction of the plurality of contact portions 18Aa, 18Ab with respect to the stretching direction BL of the shoulder belt 6a is adjusted appropriately, and the contact area by the contact portions 18Aa, 18Ab is high within the variable range of the anchor 8 position. It is preferable to overlap in the vertical direction as much as possible.

  Further, in the present embodiment, the arm portion 17A is curved so as to protrude in the direction away from the upper body surface of the driver 1 (that is, the front side of the vehicle), and the elastic force of the arm portion 17A is used, A higher contact surface pressure is obtained at the contact portion 18Aa.

  In the present embodiment, the rigidity of the arm portion 17A between the base portions 14Aa and 14Ab and the contact portions 18Aa and 18Ab is higher than that of other portions between them (particularly, the torsional rigidity around the stretching axis of the shoulder belt 6a). ) Is provided with a low fragile portion 24. With this configuration, when the upper body of the driver 1 is twisted due to vehicle behavior or the like, the arm portion 17A bends with the fragile portion 24 as a fulcrum, thereby twisting the base portions 14Aa and 14Ab and the shoulder belt 6a. It is possible to suppress the contact surface pressure of the contact portions 18Aa and 18Ab from becoming too high while suppressing the collision safety by the seat belt 6 from being impaired. In this case, the fragile portion 24 is set to be bent in a situation where a contact surface pressure higher than an intended contact surface pressure acts on the contact portions 18Aa and 18Ab. Moreover, as shown in FIG. 11, you may provide the rib 25 extended along a longitudinal direction at the front-end | tip part side of 15 A of pad parts. In this case, a difference in rigidity may be generated depending on the presence / absence of the rib 25, and a portion where the rib 25 is not set may be used as the fragile portion.

  (Third Embodiment) FIG. 14 is a perspective view of the driving posture control device, FIG. 15 is a sectional view of the contact mechanism of the driving posture control device (CC sectional view of FIG. 14), and FIG. It is a top view which shows a back surface side. In addition, in this embodiment, the component similar to the said embodiment is included. Therefore, the same reference numerals are given to these components, and redundant description is omitted below.

  The contact mechanism 13B according to the present embodiment can be used in place of the contact mechanism 13 according to the first embodiment, and includes two base portions 14Aa similar to the contact mechanism 13A according to the second embodiment. 14Ab and a pad portion 15B having a similar planar shape.

  However, in the present embodiment, a number of protruding contact portions 26 are provided on the back surface of the pad portion 15B (arm portion 17B), and the installation density of the contact portions 26 is changed along the longitudinal direction of the arm portion 17B. The density of the contact portion 26 is increased (closely) toward the tip end side, and the density of the contact portion 26 is decreased (coarse) toward the base portion 14Aa side. With this configuration, the rigidity of the pad portion 15B increases as the pad portion 15B is separated from the shoulder belt 6a (base portions 14Aa and 14Ab), and the same effect as that provided by the fragile portion 24 in the second embodiment can be obtained. Note that the density of the contact portion 26 and the rigidity of the pad portion 15B may be changed stepwise instead of continuously.

  Moreover, in this embodiment, the height from the back surface of the arm part 17B of the contact part 26 is made high, so that it separates from the shoulder belt 6a (base | substrate part 14Aa, 14Ab). According to such a configuration, the contact surface pressure increases toward the tip end side of the arm portion 17B, and the peak position (near the tip portion) where the contact surface pressure peaks and the contact region (base portions 14Aa and 14Ab) by the seat belt 6 are obtained. Since a low surface pressure contact region having a low contact surface pressure is set during this period, there is an advantage that the masking effect or the phantom sensation effect can be easily obtained. In addition, by gradually increasing the height of the contact portion 26, there is an advantage that the followability to the surface unevenness and posture change of the driver 1 is improved. Note that the contact surface pressure may be changed stepwise instead of continuously.

  However, in the present embodiment, the pad portion 15B (arm portion 17B) is formed to be thinner, and a wire 37 made of a shape memory alloy is embedded therein. The wire 37 is curved so as to protrude in a direction away from the upper body surface of the driver 1, and a state in which the radius of curvature is smaller is a memory shape, and an electric heating mechanism (not shown) is provided. When 37 is energized and heated, the radius of curvature is made small. The energization heating mechanism can be constructed by drawing the wires through the inside of the pad portion 15B and the inside of the seat belt 6 from the electrodes provided at both ends of the wire 37 to the vehicle body side.

  Therefore, when the turning of the vehicle is detected by the steering angle or the like of the steering, the energization heating mechanism is controlled by a control mechanism (not shown) such as an ECU, and the wire 37 is heated and bent to increase the contact surface pressure. Can do. That is, this embodiment embodies a contact surface pressure variable mechanism that changes the contact surface pressure with the driver 1 of the contact mechanism 13C according to the behavior of the vehicle. In addition to the turning of the vehicle, the posture (position of the upper body) of the driver 1 or a change thereof may be detected as appropriate using a sensor, and the contact surface pressure may be variably controlled based on the detection result.

  According to the present embodiment described above, since the contact surface pressure variable mechanism is provided, the masking effect and the phantom sensation effect can be obtained only when necessary, thereby reducing the uncomfortable feeling when no tactile stimulation is required. In addition to the presence / absence of turning of the vehicle, the contact surface having a more appropriate size can be selected according to various parameters such as the turning radius, turning speed, the physique of the driver 1, and the position of the contact portion 18Aa. Pressure can be applied to make the above effect even more effective.

And rod-shaped pad portions 15D and 15E extending from the base portion.

  However, in the present embodiment, the pad portion 15D (arm portion 17D) is made of a highly rigid elastic member such as hard rubber, for example, and the pad portion 15D (arm portion 17D) is made thicker as it is separated from the shoulder belt 6a (base portion 14). It is higher. In addition, the arm portion 17D is curved so as to protrude in a direction away from the upper body surface of the driver 1, so that the distal end portion is expanded by using the elastic force of the arm portion 17D. A higher contact surface pressure is obtained at the portion 18D. According to this configuration, the contact mechanism 13D can be configured more compactly, the contact surface pressure by the contact mechanism 13D can be ensured, and the masking effect or phantom sensation effect can be obtained more reliably. The same effect as that in which the fragile portion 24 is provided in the second embodiment can be obtained.
