Description

  The present invention relates to a vehicle harness arrangement structure, and more particularly to a harness arrangement structure in which a harness is arranged in an intermediate pillar in which an impact absorbing material is arranged in a space between a pillar structure and a pillar trim.

  In recent years, a so-called curtain airbag device in which an airbag body is deployed and inflated in a curtain shape on a side portion of a vehicle interior in order to protect passengers in the vehicle interior when a vehicle crashes or rolls over is well known. (For example, see Patent Documents 1 and 2), some of which have already been put to practical use.

  In the case of this curtain airbag device, it is necessary to expand and inflate the airbag over a wider area compared to the airbag device provided in the driver's seat and passenger seat, and in particular, the airbag is activated during rollover or rollover prediction. In order to allow the rollover to occur, an inflator for supplying gas is disposed, for example, at the upper part of the rearmost pillar in order to supply the gas from the upper part on the center side of the airbag and deploy the airbag at an early stage. It has been proposed.

On the other hand, a control unit that controls the operation of in-vehicle components including an airbag device is generally arranged, for example, on a floor portion between a driver seat and a passenger seat. As described above, when the inflator is arranged on the upper part of the rearmost pillar, the harness for supplying the operation signal from the control unit to the inflator is arranged via the rearmost pillar.

  By the way, in order to quickly and evenly inflate and inflate the entire curtain airbag, it is preferable to dispose the inflator at a position as close as possible to the gas supply port usually provided at the upper center. For this reason, it is conceivable to arrange the inflator at a position as close as possible to the center in the front-rear direction of the roof side rail that extends in the front-rear direction of the vehicle body on the roof side. In this case, if the harness is arranged via the rearmost pillar as in the prior art, the arrangement length of the expensive harness becomes very long, the workability of attaching the harness and the like deteriorates, and the cost increases. There is a problem.

  For this reason, if the harness can be disposed via the intermediate pillar closest to both the inflator and the control unit, the harness length can be shortened, which is very convenient. Thus, it is desired to be able to arrange a harness for supplying signals to in-vehicle components including an airbag device or the like without any trouble using an intermediate pillar.

  However, the intermediate pillar is narrower than the rearmost pillar and the internal space is not sufficient, and it is necessary to accommodate a part of the mechanism of the seat belt device for the driver's seat or the passenger seat. In particular, it is required to have an impact absorbing material for absorbing an impact when the head collides with the inside. Accordingly, there is a problem that it is very difficult to arrange the harness via the intermediate pillar.

  The present invention has been made in view of such technical problems, and is intended to enable a harness to be disposed in an intermediate pillar without hindrance without impairing the capacity and shock absorption of a seat belt mechanism of the intermediate pillar. Objective.

For this reason, the first invention of the present application is that when the occupant comes into contact with the pillar trim in the space between the pillar structure that forms the intermediate pillar portion of the vehicle body and the pillar trim that covers the pillar structure from the passenger compartment. A harness arrangement structure for a vehicle in which a harness for supplying a signal to a vehicle-mounted component is arranged in the space of the intermediate pillar in which an impact absorbing material that absorbs the impact of
The pillar structure is provided with an anchor member that supports a webbing of a seat belt device that can restrain an occupant seated in the seat, and the anchor member includes a webbing support part that supports the webbing by inserting the webbing in a vertical direction. And a guide part that allows the vertical position of the webbing support part to be adjusted, and the harness extends vertically between the guide part and the pillar structure and absorbs the shock. The guide portion is disposed in the vertical direction as a whole while passing through a predetermined space portion that avoids interference with the material, and the guide portion is displaced outwardly from the passenger compartment when the occupant comes into contact with the guide portion or the webbing support portion. Te so that the possible shock absorption, by being placed in a predetermined distance or more from the pillar structure, shock absorption between the pillar structure and the guide portion Of which free space is secured, the harness, this is arranged in a free space, it is obtained by it said.

Further, according to a second aspect of the present invention, in the first aspect , the pillar trim is made of a synthetic resin, and the shock absorber is formed integrally with the synthetic resin pillar trim. It is made of metal.

Still further, according to a third invention of the present application, in the first or second invention, the pillar trim is composed of an upper trim and a lower trim formed separately from each other, and the anchor member is a pillar structure. And the webbing is formed in the space between the pillar trim and the pillar structure through an opening formed in or near the connecting portion between the lower trim and the upper trim. From the upper trim to the vehicle interior side along the longitudinal direction of the upper trim to the webbing support portion.

Still further, according to a fourth invention of the present application, in any one of the first to third inventions, the in-vehicle component is installed in a vehicle body roof and in the vicinity thereof, and air for occupant protection is provided when the vehicle is in a predetermined condition. This is an airbag device for deploying a bag.

According to the first invention of the present application, the harness extends in the vertical direction between the guide portion of the anchor member of the seat belt device and the pillar structure, and avoids interference with the shock absorber. Since it is arranged in the vertical direction as a whole while passing through the section, without impairing the shock absorption by the shock absorber of the intermediate pillar, and without impairing the function and accommodation of the seat belt mechanism such as the anchor member The harness can be disposed in the intermediate pillar without any trouble.
In particular, the guide portion is installed at a predetermined distance or more away from the pillar structure so that when the occupant comes into contact with the guide portion or the webbing support portion, the guide portion is displaced outward from the passenger compartment and can absorb the shock. As a result, the shock absorption of the intermediate pillar can be further increased, and the harness can be disposed by utilizing the space between the two due to the separation of the guide portion from the pillar structure. In this case, since the harness can be disposed in such a large space, when the occupant adjusts the height of the webbing support portion, interference between the harness and the webbing support portion can be suppressed.

Further, according to the second invention of the present application, the same operational effects as those of the first invention can be obtained. In particular, the pillar trim is made of a synthetic resin, and the shock absorber is integrated with the synthetic resin pillar trim. On the other hand, since the guide part is made of metal, when the occupant comes into contact with the intermediate pillar with a relatively large impact, the resin pillar trim and the metal guide part are more effective than the metal guide part. The integrated shock absorbing material is deformed to a greater extent and effectively absorbs the shock, thereby effectively protecting the harness disposed between the metal guide portion and the pillar structure with relatively small deformation. be able to.

Still further, according to the third invention of the present application, the same effects as those of the first or second invention can be obtained. In particular, the webbing is provided at or near the connecting portion between the lower trim and the upper trim. Through the formed opening, it extends from the space between the pillar trim and the pillar structure to the vehicle interior, and extends from the upper trim to the webbing support portion along the longitudinal direction of the upper trim on the vehicle interior side. Since the pillar trim can be interposed between the webbing and the harness above the opening, it is possible to reliably prevent the webbing and the harness from interfering with each other.

Still further, according to the fourth invention of the present application, a harness that is installed in the vehicle body roof and in the vicinity thereof and that supplies a signal to an airbag device that deploys an occupant protection airbag when the vehicle is in a predetermined condition is disposed. At this time, the same operational effects as any one of the first to third aspects of the invention can be achieved.

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.
FIG. 1 is a perspective view partially showing a structure of a vehicle body side part and a floor part of an automobile according to an embodiment of the present invention. In FIG. 1, only the right side portion of the vehicle body is shown, but the left side portion of the vehicle body is also symmetrical with the right side, but basically has the same configuration. In the following description, the description will be given mainly by taking the right side of the vehicle body as an example, but this description also applies to the left side.

  As shown in FIG. 1, in the automobile, an intermediate pillar portion 2 that partitions a front door opening 1 </ b> F and a rear door opening 1 </ b> R of a side panel 1 that constitutes a vehicle body side portion is formed integrally with the side panel 1. Yes. The upper end side of the intermediate pillar portion 2 is connected to the roof side rail portion 5 that supports the left and right side portions of the roof portion (not shown) at the upper end of the left and right side portions of the vehicle body, and extends in the vehicle body longitudinal direction. At the lower ends of the left and right side portions, the left and right side portions of the floor portion 8 (floor panel) are supported and connected to the side sill portion 6 that extends in the longitudinal direction of the vehicle body. The intermediate pillar portion 2 is a combination of an outer plate (outer panel: not shown in FIG. 1) and an inner plate 3 (pillar inner panel) integrated with an outer plate of the side panel 1, or a reinforcing plate (lane) between them. (Force: not shown) is sandwiched and joined.

  FIG. 2 is a perspective view showing a relatively upper portion of the intermediate pillar portion with the pillar trim removed, and FIG. 3 is a front view showing the relatively upper portion of the intermediate pillar with the pillar trim attached. As can be seen from these drawings, the intermediate pillar 20 is configured by covering the passenger compartment side of the intermediate pillar portion 2 (that is, the passenger compartment side of the pillar inner panel 3) with the pillar trim 22. The pillar trim 22 can serve as a vehicle interior product corresponding to the intermediate pillar portion 2, and is preferably manufactured by molding using a synthetic resin material. A space 25 (trim space) is formed by the pillar inner panel 3 and the pillar trim 22 in a state where the pillar trim 22 is attached to the passenger compartment side of the intermediate pillar portion 2.

  The intermediate pillar portion 2 is located slightly behind the driver's seat (the passenger seat on the left side of the vehicle body) and slightly rearward. A so-called three-point seat for the driver's seat is placed at a relatively upper position of the intermediate pillar portion 2. An adjuster unit 30 is attached as an anchor portion of the belt device. As will be described in detail later, the adjuster unit 30 supports the webbing 15 that can restrain an occupant seated in the driver's seat. On the other hand, a so-called pretensioner mechanism portion 14 of the seat belt device is disposed at a relatively appropriate position below the intermediate pillar portion 2. The pretensioner mechanism 14 is the same as that well known in the art. Most of these adjuster units 30 and the pretensioner mechanism portion 14 are accommodated in the trim space 25 of the intermediate pillar 20.

  In addition, the automobile is equipped with a so-called curtain airbag device that deploys and inflates the airbag body 10 in a curtain shape on the side of the vehicle interior in order to protect the passengers in the vehicle interior when the vehicle collides or rolls over. Has been. The airbag main body 10 covers at least the inside of the side part of the passenger compartment including the window glass (not shown) of the front door and the rear door (both not shown) and the intermediate pillar 20 when deployed and inflated.

  The airbag body 10 of the curtain airbag device is disposed along the roof side rail portion 5 in a folded state. The inflator 12 for supplying gas to the airbag main body 10 is preferably arranged as close as possible to the gas supply port provided in the approximate center of the airbag main body 10 in the longitudinal direction of the vehicle body. Therefore, in the present embodiment, As shown in more detail in FIG. 2, the inflator 12 is disposed near the center of the roof side rail portion 5 in the longitudinal direction of the vehicle body, that is, near the upper end of the intermediate pillar 20.

In the present embodiment, more preferably, the curtain airbag device is adapted to roll over to operate the airbag body 10 at the time of rollover or rollover prediction, and the inflator 12 has a predetermined compressed gas inside. Is a cylindrical cylinder structure.
That is, the inflator 12 is configured to operate when a rollover of the vehicle is detected or predicted by a rollover detection sensor (not shown) installed in the center of the vehicle. Since it is the same as that conventionally known, it will not be described in detail. However, when the rollover detection sensor detects a vehicle body roll angle of a predetermined angle or more (for example, 5 to 30 degrees), the control unit C (see FIG. 1). ) Is determined to be rollover or rollover prediction, and an operation signal is output to the inflator 12.

  The control unit C can control the operation of in-vehicle components including the curtain airbag device, the driver and passenger airbag devices, and the pretensioner 14 of the seat belt device. For example, it is arranged on the floor portion between the driver's seat and the passenger seat as a location that is least affected. The control unit C is preferably configured with, for example, a microcomputer including a CPU as a main part.

In the present embodiment, when the harness W for supplying the operation signal from the control unit C to the inflator 12 is disposed, in order to shorten the length of the expensive harness W as much as possible, the internal space of the intermediate pillar 20 To use. Hereinafter, the arrangement structure of the harness W using the intermediate pillar 20 will be described.
4A and 4B are explanatory views of the adjuster unit 30 as an anchor member of the seat belt device, in which FIG. 4A is a perspective view seen from the vehicle interior side, and FIG. 4B is a perspective view seen from the vehicle exterior side. It is. FIG. 5 is an explanatory view showing a state in which a webbing support portion for a shoulder anchor of a seat belt, which is called a so-called D ring 31, is removed from the adjuster unit 30, and FIG. (B) is the perspective view seen from the vehicle compartment outer side.

  As can be seen from FIGS. 2 and 3, an adjuster unit 30 as an anchor member for supporting the webbing 15 of the seat belt device capable of restraining an occupant seated in the driver's seat is located at a relatively upper position of the intermediate pillar portion 2. Is attached. As can be clearly understood from FIG. 4, the adjuster unit 30 has a so-called D-ring 31 as a webbing support portion for inserting and supporting the webbing 15 and is capable of adjusting the vertical position of the D-ring 31 by extending in the vertical direction. And a vertical position adjustment mechanism 40 as a guide portion. The pillar inner panel 3 is provided with a concave guide groove 3g having a predetermined width extending in the vertical direction in order to guide the drawing operation and the winding operation of the webbing 15. By providing such a concave groove 3g, it is possible to contribute to the improvement of the rigidity of the pillar inner panel 3.

  As can be clearly understood from FIG. 5, the vertical position adjusting mechanism 40 includes a lower rail 41 that is extended and fixed in the vertical direction on the pillar inner panel 3 of the intermediate pillar portion 2, and is located closer to the vehicle interior side than the lower rail 41. An upper rail 44 that is arranged and supported so as to be slidable in the vertical direction with respect to the lower rail 41, and a slider 45 fixed to the vehicle interior side of the upper rail 44 are provided. A boss portion 46 is provided for fastening and fixing according to FIG. The boss portion 46 is covered with a plastic cover 37 (see FIG. 5) after the D-ring 31 is attached.

  The lower rail 41 is formed with a plurality of holes 41h arranged in the vertical direction, and a positioning projection 44p provided on the back side of the upper rail 44 fits into any of the plurality of holes 41h. Thus, the vertical position of the upper rail 44 (that is, the slider 45 and the D ring 31) is determined. The slider 45 is provided with a release button 32 for releasing the fitting state of the positioning protrusion 44p with respect to the hole 41h (see FIG. 4). By pressing the release button 32, for example, the fitting state is set. The position of the D ring 31 fixed to the slider 45 can be adjusted by releasing the slider 45 and sliding the slider 45 in the vertical direction and fitting the positioning projection 44p into the other hole 41h. The release button 32 is covered with a plastic cap 38 at normal times when position adjustment is not performed. The structure and function of the vertical position adjusting mechanism 40 are the same as those conventionally known.

  The lower rail 41 includes upper and lower mounting legs 42 and 43 that protrude outward from the passenger compartment. The terminal portion 43b of the lower mounting leg 43 is engaged with a vehicle body longitudinal direction groove 3s (see FIG. 2) provided on the pillar inner panel 3, and in this engaged state, the terminal portion of the upper mounting leg 42 is engaged. 42 b is fastened and fixed to the pillar inner panel 3 using the bolt member 49, whereby the lower rail 41 is fixed on the pillar inner panel 3. At this time, the lower rail 41 is set apart from the surface of the pillar inner panel 3 by a distance corresponding to the height of the upper and lower mounting leg portions 42 and 43. In this embodiment, the distance is set to 10 mm to 30 mm, for example.

Therefore, when the occupant hits the adjuster unit 30 (that is, the vertical position adjusting mechanism 40 or the D ring 31), the vertical position adjusting mechanism 40 is the distance that the lower rail 41 is separated from the surface of the pillar inner panel 3. Accordingly, the vehicle can be displaced outward. Thereby, the shock absorption property of the intermediate pillar 20 can be further increased.
Further, as will be described later, the harness W (having a diameter of, for example, about 5 mm) can be disposed by utilizing the space between the lower rail 41 and the pillar inner panel 3 that is separated from the pillar inner panel 3. In this case, since the harness W can be disposed in such a large space, interference between the harness W and the vertical position adjusting mechanism 40 can be suppressed when the occupant adjusts the height of the D-ring 31. In addition, when the occupant contacts the adjuster unit 30 (that is, the vertical position adjusting mechanism 40 or the D-ring 31), the distance between the lower rail 41 and the pillar inner panel 3 is set as large as possible. Thus, interference with the harness W can be suppressed.

  In the present embodiment, as described above, the lower rail 41 is separated from the pillar inner panel 3 by providing the lower rail 41 with upper and lower mounting legs 42 and 43 each having a predetermined height. In addition, the lower rail can be formed flat, and the pillar inner panel can be provided with an attachment base portion having a predetermined height so that the same effect can be obtained.

  The lower rail 41, the upper rail 44, and the slider 45 are all made of a metal such as a steel plate, while the pillar trim 22 is made of a synthetic resin as described above. As shown in FIGS. 6 and 7 to be described later, a plurality of shock absorbers that absorb an impact when the occupant comes into contact with the pillar trim 22 on the back surface side (outside of the passenger compartment) of the pillar trim 22 made of synthetic resin. The ribs R are integrally formed. These ribs R extend in the horizontal direction on the back surface side of the pillar trim 22 and project by a predetermined amount outward from the passenger compartment. The protruding amount of the rib R to the outside of the passenger compartment is such that the distance between the tip of the rib R and the pillar inner panel 3 is larger than the diameter of the harness W in a state where the pillar trim 22 covers the pillar inner panel 3. Is set to

  Since the rib R is formed on the back side of the pillar trim 22, the rib R is formed between the pillar trim 22 and the pillar inner panel 3 when the pillar inner panel 3 of the intermediate pillar portion 2 is covered. It will be located in the trim space 25. The rib R is more preferably integrally formed when the pillar trim 22 is formed. However, a rib formed separately from the trim main body can be retrofitted to the rear surface side of the trim main body by bonding or welding.

  As described above, the pillar trim 22 is made of synthetic resin, the rib R for absorbing shock is formed integrally with the synthetic resin pillar trim 22, and the vertical position adjusting mechanism 40 is made of metal. When an occupant hits the intermediate pillar 20 with a relatively large impact, the resin pillar trim 22 and the rib R integrated therewith are more greatly deformed and effective than the metal vertical position adjusting mechanism 40. By absorbing the shock, the harness W disposed between the metal vertical position adjusting mechanism 40 and the pillar inner panel 3 with relatively small deformation can be effectively protected.

  Since the pillar trim 22 is relatively large as a resin molded product, in this embodiment, from the viewpoint of facilitating molding and handling, the pillar trim 22 is divided into a separate upper trim 23 and lower trim 24. The configuration is as follows. The upper trim 23 and the lower trim 24 are formed so that the width of the upper trim 23 is relatively narrow and the width of the lower trim 24 is relatively wide corresponding to the shape of the intermediate pillar portion 2 that they cover. Further, when the occupant hits the intermediate pillar 20, the rib R as the shock absorber is mainly provided on the upper trim 23, particularly from the viewpoint of more effectively protecting the occupant's head.

  The adjuster unit 30 is installed at a portion of the pillar inner panel 3 that is covered with the upper trim 23, and at or near the connecting portion between the upper trim 23 and the lower trim 24, the interior of the trim space 25 moves into the vehicle interior. An opening 22H through which the webbing 15 is drawn is formed. The webbing 15 extending from the pretensioner mechanism portion 14 extends from the trim space 25 into the vehicle interior via the opening 22H, and the vehicle interior side of the upper trim 23 extends in the longitudinal direction (vertical direction) of the upper trim 23. ) To the D ring 31. And after inserting the slot 31s of this D ring 31, it is turned down toward the bottom.

  That is, after the webbing 15 is pulled out from the opening 22H into the vehicle interior, it extends upward on the vehicle interior side along the upper trim 23 from the upper trim 23 and reaches the D-ring 31. On the other hand, since the upper trim 23 can be interposed between the webbing 15 and the harness W, the webbing 15 and the harness W can be reliably prevented from interfering with each other.

  FIG. 6 is a front view showing the arrangement structure of the harness in the intermediate pillar. FIG. 7 is a longitudinal sectional view taken along line Y7-Y7 in FIG. As shown in these drawings, the harness W is formed between the vertical position adjusting mechanism 40 of the adjuster unit 30 and the pillar inner panel 3 such that the lower rail 41 of the vertical position adjusting mechanism 40 is separated from the pillar inner panel 3. It is extended in the vertical direction using the space part.

In this embodiment, the diameter of the harness W is about 5 mm, and the distance is set to 10 mm to 30 mm. Therefore, in this region, there is no possibility that the harness W interferes with components of the adjuster unit 30 and the harness W can be easily disposed.
Further, in this region, as described above, when the distance between the lower rail 41 and the pillar inner panel 3 is set as large as possible, the occupant operates the adjuster unit 30 to adjust the height of the D ring 31. It can suppress that the upper rail 44 which connects the moving D ring 31 interferes with the harness W.

In the vicinity of the terminal portion 42b of the upper mounting leg portion 42 of the lower rail 41, the harness W is routed slightly behind the terminal portion 42b in order to avoid interference with the terminal portion 42b. Yes. In this case, the harness W is arranged so as not to overlap with the rib R in a side view shown in FIG. 6 when exceeding the bank portion 3d (see FIG. 2) that protrudes toward the passenger compartment side of the pillar inner panel 3. Thus, the interference between the harness W and the rib R can be further prevented.
Further, also in the vicinity of the terminal portion 43b of the lower mounting leg portion 43 of the lower rail 41, in order to avoid interference with the terminal portion 43b, when the harness W crosses the bank portion 3d of the pillar inner panel 3, In this case, in order to avoid interference with the rib R, the harness W is horizontally moved so as to pass through the space between the adjacent ribs R. The direction of the rib R is changed to a relatively rear portion of the rib R, and the rib R is extended downward between the tip of the rib R and the pillar inner panel 3.

  In this case, in order to avoid interference between the harness W and the mechanisms and members inside the intermediate pillar 20, the harness W is routed to the relatively rear part in the intermediate pillar 20. This is because, based on the positional relationship with the driver's seat (or passenger seat), the rear portion of the intermediate pillar 20 is considered to be less frequently or more likely to require shock absorption than the front portion.

  As described above, according to the present embodiment, the harness W extends in the vertical direction between the vertical position adjusting mechanism 40 of the adjuster unit 30 of the seat belt device and the pillar inner panel 3, and the pillar trim. Since it is arranged in the vertical direction as a whole while passing through a predetermined space that avoids interference with the shock absorbing rib R, the adjuster unit does not impair the shock absorption by the rib R of the intermediate pillar 20. The harness W can be disposed in the intermediate pillar 20 without hindrance without impairing the function and capacity of the seat belt mechanism such as 30.

  The present invention relates to a harness arrangement structure in which a harness is arranged in an intermediate pillar in which a shock absorbing material is arranged in a space between a pillar structure and a pillar trim. For example, a signal is transmitted to an inflator of a so-called curtain airbag device. This harness can be used effectively when the harness that supplies the power is installed using an intermediate pillar, and the harness can be installed in the intermediate pillar without any problem without impairing the capacity and shock absorption of the seat belt mechanism of the intermediate pillar. become able to.

Although the above explanation is about the case where a harness for supplying a signal to an inflator of a so-called curtain airbag device is provided using an intermediate pillar, the present invention is limited to such a case. However, if the intermediate pillar is used, the present invention can be effectively applied even when a harness for other in-vehicle components is provided.
Thus, it goes without saying that the present invention is not limited to the above-described embodiment, and various modifications and improvements can be made without departing from the scope of the invention.
