Description

  The present invention relates to an instrument panel structure provided in an automobile compartment, and in particular, to an instrument panel structure arranged so that an airbag body of an airbag system is inflated.

  In recent years, the number of vehicles equipped with airbag systems for protecting passengers has increased, and for passengers in front passenger seats, the top panel of the instrument panel is mainly installed inside the instrument panel. The bag-shaped airbag body is designed to swell obliquely upward from the passenger seat toward the passenger seat.

  The inflated airbag body is supported at the lower part by the upper surface of the instrument panel and supported at the upper part by the interior of the windshield, thereby restraining the movement of the airbag body. In addition, the shock absorbing function for the occupant is properly exhibited.

In addition, in order to smoothly inflate the lower portion of the airbag body that is in contact with the upper surface of the instrument panel, the instrument panel is displaced downwardly by the pressure applied to the instrument panel due to the inflation of the airbag body. An invention of a panel structure has been proposed (Patent Document 1).
JP 11-208403 A

  By the way, the vehicle is required to improve the occupant's comfortability in the passenger compartment. From this viewpoint, it is required to secure a wider passenger compartment space.

  On the other hand, the above-described proposed technique displaces the entire instrument panel in the inflated state of the airbag body, but does not meet the demand for securing a large vehicle interior space.

  The present invention has been made in view of the above circumstances, and provides an instrument panel structure capable of stabilizing the position and posture of an inflated airbag body while ensuring a wide vehicle interior space. It is intended.

  The instrument panel structure according to the present invention is configured such that when the airbag is not in operation, the length in the longitudinal direction of the vehicle body is short to suppress the occupied volume in the vehicle interior space, and when the airbag body bulges, A portion that is at least a part of the ment panel and supports the inflated airbag body from below protrudes rearward of the vehicle body and stably restrains the airbag body.

  That is, the first instrument panel structure according to the present invention includes an instrument panel that includes an airbag and is fixed to the vehicle body, and is provided at least on the upper surface of the instrument panel by the operation of the airbag. A receiving surface that supports the airbag main body from below is projected toward the rear of the vehicle body.

  Here, as long as the receiving surface protrudes toward the rear of the vehicle body, any type of protruding operation may be employed. For example, the receiving surface protrudes rearward of the vehicle body by sliding backward. The rear surface of the receiving surface may be supported around an axis extending in the vehicle width direction, and the receiving surface may be rotated around the axis so as to protrude rearward of the vehicle body. Good.

  The receiving surface may be a surface of a plate-like body or a surface of a three-dimensional structure, and such a plate-like body or a three-dimensional structure may slide or rotate. As long as it is formed as an upward facing surface that supports the airbag body from below.

  Note that the operation of the airbag means the operation of the airbag system, not only the operation of the airbag body inflating, from the detection of the collision to the ignition of the inflator, This means that the operation before the airbag body is inflated is also included.

  Accordingly, the protruding operation of the receiving surface starts due to the fact that the airbag body has actually expanded (in time series, the expanding operation of the airbag body precedes, and then the protruding operation of the receiving surface) Is not limited to those that start due to the detection of a collision, etc. (time-sequential projection operation of the receiving surface precedes, and then the airbag body inflates) May be started).

  Further, the second instrument panel structure according to the present invention includes an airbag, a fixed instrument panel fixed to the vehicle body, and movable in the vehicle longitudinal direction with respect to the fixed instrument panel, And a movable instrument panel having a receiving surface for supporting the airbag main body inflated from the fixed instrument panel from below in a protruding state of moving to the rear of the vehicle body.

  Here, the protruding state moved rearward of the vehicle body means a state protruding into the space in the vehicle interior.

  The receiving surface only needs to be formed as an upward facing surface that supports the airbag body from below by moving the movable instrument panel to the rear of the vehicle body.

  According to the instrument panel structure of the present invention, when the airbag is not in operation, the length in the longitudinal direction of the vehicle body is short, so that the occupied volume in the vehicle interior space can be suppressed. When the bag body bulges out, at least part of the instrument panel and the part that supports the bulged airbag body from below protrudes toward the rear of the vehicle body, so that the airbag body can be stably restrained. Thus, it is possible to achieve both a large vehicle interior space and the stability of the airbag body.

  That is, according to the first instrument panel structure of the present invention, the receiving surface protruding rearward of the vehicle body by the operation of the airbag supports the expanded airbag body from below, so that the receiving surface does not protrude. Compared to the above, the position, posture, and shape of the inflated airbag body can be stabilized.

  On the other hand, since the receiving surface does not forcibly protrude to the rear of the vehicle body when the airbag is not in operation, the amount of protrusion to the rear of the vehicle body can be suppressed, and a large space in the vehicle interior can be secured. it can.

  Therefore, it is possible to achieve both a large vehicle interior space and the stability of the airbag body.

  Further, according to the second instrument panel structure of the present invention, when the movable instrument panel is located at the rear of the vehicle body, the receiving surface of the movable instrument panel has the bulging airbag body. Since the instrument panel is supported from below, the position, posture, and shape of the bulged airbag body can be stabilized as compared with the instrument panel that does not move.

  On the other hand, since the movable instrument panel does not move to the rear of the vehicle body when the airbag is not in operation, the amount of protrusion to the rear of the vehicle body can be suppressed, and a large space in the vehicle interior can be secured. .

  Therefore, it is possible to achieve both a large vehicle interior space and the stability of the airbag body.

  Hereinafter, the best embodiment of the instrument panel structure according to the present invention will be described with reference to the drawings.

  FIG. 1 is a schematic perspective view showing an instrument panel 10 to which the instrument panel structure of the present invention is applied, and this instrument panel 10 is installed in a front part of a vehicle interior of a vehicle.

  Here, the portion where the AA line indicating the cross section is described is a portion facing the front seat occupant, particularly the passenger seat, in the passenger compartment, and the cross section along the AA line is shown in FIGS. It has become a thing.

  That is, the instrument panel 10 is movable to be movable in a vehicle longitudinal direction (vehicle front Fr, vehicle rear Rr) within a predetermined range with respect to the fixed instrument panel 20 fixed to the vehicle body and the fixed instrument panel 20. And an instrument panel 30.

  In the structure in which the movable instrument panel 30 is movable in the longitudinal direction of the vehicle body, both side portions of the movable instrument panel 30 are connected to the fixed instrument panel 20 by, for example, movable skeleton members 40 and 40 shown in FIGS. It is realized by the structure.

  That is, as shown in the exploded perspective view of FIG. 4, the movable skeleton member 40 is connected to the fixed instrument panel 20 and is connected to the guide member 41 extending in the longitudinal direction of the vehicle body and the movable instrument panel 30. 41, a slide member 42 that is slidable in the longitudinal direction of the vehicle body, an instrument panel inflator 45 fixed to an end of the slide member 42 on the vehicle body front Fr side, an instrument panel inflator 45, Two grooves 43a and 43a that are loosely fitted between the two rails 41a and 41a of the guide member 41 and the receiving plate 44 disposed on the front Fr side of the vehicle body with a slight gap are formed so as to be slidable on the guide member 41. The holes 43b through which the protrusions 44a of the receiving plate 44 are inserted and the protrusions 42a of the slide member 42 are inserted. Hole 43c is configured such that a connecting plate 43 for connecting the receiving plate 44 is drilled and the slide member 42.

  Here, the hole 43c of the connecting plate 43 into which the protrusion 42a of the slide member 42 is inserted communicates with the outside on the vehicle body rear side Rr side via the constricted portions 43d and 43d. The opposing distance between the two constricted portions 43d and 43d is smaller than the diameter of the projection 42a inserted through the hole 43c. However, when a predetermined load or more is applied to the rear portion Rr of the vehicle body, the projection 42a is constricted. The space between the portions 43d and 43d is widened so that it can be detached from the hole 43c to the vehicle body rear side Rr.

  When the inflator 45 is actuated, the load (pressure) acting on the inner space formed by the receiving plate 44, the slide member 42, the guide member 41, and the connecting plate 43 is set to a load higher than the predetermined value. However, the load is set so as not to reach a predetermined load or more when the slide member 42 is pulled to the rear Rr side of the vehicle by hand without operating the inflator 45.

  That is, as shown in FIG. 5 (a), when the slide member 42 is pulled toward the vehicle body rear side Rr from a state where most of the slide member 42 in the length direction is inserted into the guide member 41, ), The slide member 42, the connecting plate 43, and the receiving plate 44 are integrally displaced toward the rear of the vehicle body Rr.

  On the other hand, when the inflator 45 is operated, the pressure in the internal space surrounded by the receiving plate 44, the slide member 42, the guide member 41, and the connecting plate 43 is rapidly increased to a high pressure. A load of a predetermined amount or more to the vehicle body rear side Rr acts on the projection 42a of 42, and the hole 43c is detached, so that only the slide member 42 is displaced to the vehicle body rear side Rr as shown in FIG.

  The instrument panel inflator 45 is controlled by a control unit (not shown) so that the instrument panel inflator 45 starts to operate slightly earlier than an airbag inflator 81 described later.

  As shown in FIG. 2, an airbag system 80 is provided on the inside (lower part) of the upper wall portion of the fixed instrument panel 20, and when the airbag is activated, based on detection information such as a gravity sensor (not shown). The airbag body 82 is inflated by the action of the airbag inflator 81, the upper wall portion is split by the pressure of the inflation, and the airbag body 82 is expanded into the vehicle interior.

  Here, FIG. 2 shows a state where the movable skeleton member 40 is in a state where the overall length in the longitudinal direction of the vehicle body is the shortest as shown in FIG. 5 (a). At this time, the movable instrument panel 30 is located closest to the vehicle body front side Fr in the movable range in the longitudinal direction of the vehicle body. At this time, the space length in the vehicle longitudinal direction in the vehicle interior is the longest length L1.

  On the other hand, FIG. 3 shows a state in which the airbag system 80 is activated and the airbag main body 82 is inflated into the vehicle interior, but prior to the operation of the airbag inflator 81, As shown in FIG. 5C, the instrument panel inflator 45 is actuated to show that the overall length in the longitudinal direction of the vehicle body is in the longest state. The panel 30 is displaced to the rear of the vehicle body Rr with respect to the fixed instrument panel 20 due to the extension of the movable skeleton member 40, and the space length in the longitudinal direction of the vehicle body in the vehicle interior is the shortest length L2 (<L1). .

  The front edge of the movable instrument panel 30 is a fixed instrument panel during the displacement period of the movable instrument panel 30 from the longest state of the vehicle interior space shown in FIG. 2 to the shortest state of the vehicle interior space shown in FIG. The upper surface 21 of the upper wall portion 20 is displaced rearward Rr so as to come into sliding contact.

  Here, as shown in FIG. 3, after the movable instrument panel 30 is retracted and displaced backward in the vehicle body Rr, the airbag body 82 is directed from the upper wall portion of the fixed instrument panel 20 toward the passenger seat passenger in the vehicle interior. The inflated airbag main body 82 is formed by a vehicle interior surface 91 of a front windshield (front glass) 90 that covers an upper space from the vehicle body front Fr side to the vehicle body rear Rr side of the instrument panel 10. The upper portion abuts and the lower portion abuts against the upper surface 31 of the movable instrument panel 30 that has been retracted (hereinafter simply referred to as the upper surface (receiving surface)). Is restrained by the vehicle interior surface 91 of the front windshield 90 and the upper surface 31 of the movable instrument panel 30. Bag body 82 by the restraint toward the passenger side to be subjected to the shock-absorbing, accurate and proper positions, can be inflated in a shape and orientation.

  On the other hand, in the non-operating state of the airbag system 80, the movable instrument panel 30 does not move to the vehicle body rearward Rr, so that it is possible to suppress the amount of protrusion to the vehicle body rearward Rr, and to The vehicle interior space can be secured widely with the directional length as the longest L1.

  Therefore, the instrument panel 10 of the present embodiment can achieve both a wide vehicle interior space and the stability of the airbag body 82.

  In addition, the movable instrument panel 30 includes an instrument panel inflator 45 different from the airbag inflator 81 for inflating the airbag body 82, and the instrument panel inflator 45 is provided on the airbag body 82. In order to move the movable instrument panel 30 to the vehicle rear side Rr prior to the inflation operation, the timing of the inflation operation of the airbag body 82 by the airbag inflator 81 and the movable instrument by the instrument panel inflator 45 are described. It is possible to control the timing of the movement operation of the panel 30 to the vehicle body rearward Rr completely independently.

  Therefore, the airbag inflator 81 and the instrument panel inflator 45 are operated so that the movement operation of the movable instrument panel 30 toward the rear Rr of the vehicle body precedes the inflation operation of the airbag body 82. When the main body 82 is inflated, the movable instrument panel 30 has already been reliably moved to the vehicle body rear side Rr, and the inflated airbag main body 82 can be reliably supported by the upper surface 31 of the movable instrument panel 30. .

  When the airbag main body 82 is completely inflated, it is necessary that the movable instrument panel 30 has already been moved to the rear of the vehicle body Rr. This is not necessarily the case before the airbag inflator 81 is operated. It is not necessary to operate the inflator 45 for the ment panel.

  That is, since the airbag inflator 81 and the instrument panel inflator 45 are different from each other, there may be a performance difference between the two inflators 81 and 45, and the airbag body 82 is inflated. There may be a time difference between the time required to move the movable instrument panel 30 and the time required to completely move the movable instrument panel 30 to the vehicle body rear side Rr, and qualitatively determine which inflator 81 or 45 is to be operated first. The operation start timings of these two inflators 81 and 45 are determined individually and specifically.

  Further, the instrument panel 10 can extend the length along the longitudinal direction of the vehicle body even when the movable skeleton member 40 is in an inoperative state of the instrument panel inflator 45 as shown in FIG. 5B. Therefore, even when the airbag main body 82 is not inflated, the movable instrument panel 30 can be moved to the state shown in FIG.

  That is, the movement of the movable instrument panel 30 toward the vehicle body rear side Rr when the airbag body 82 is not inflated is caused by the sliding friction between the guide member 41 and the slide member 42 and the rails 41a and 41a of the guide member 41. And the grooves 43a and 43a of the connecting plate 43 are prevented to some extent by a normal vehicle behavior such as simple vehicle start and stop inertia, and the movable instrument panel 30 is fixed to the fixed instrument panel. There is no displacement with respect to 20.

  However, the holding by such friction can be released by placing a finger on the handle portion 32 of the movable instrument panel 30 and applying a load to the vehicle body rear Rr or the vehicle body front Fr.

  That is, the above-described sliding friction functions as a holding unit that prevents the movable instrument panel 30 from moving toward the vehicle body rear side Rr, and also has a function of releasing this blocking state by a manual operation.

  As a result, the movable instrument panel 30 can be moved toward the vehicle body rear side Rr by manual operation of the occupant. Therefore, even when the airbag main body 82 is not inflated, the movable instrument panel 30 can be moved as required by the occupant's preference. The ment panel 30 can be arbitrarily moved to the rear Rr side of the vehicle body.

  In addition, as described above, instead of causing the sliding friction to function as the holding means, an engagement member provided on one of the movable instrument panel 30 and the fixed instrument panel 20 or the instrument panel 30 or 20; The holding means is an engaging means that is composed of an engaged part formed on the other instrument panel 20 or 30 as a part that engages with the engaging member and can be manually released from the engaged state. It can also be applied.

  By the way, since the instrument panel 10 is configured to expand and contract in the longitudinal direction of the vehicle body as a whole, for example, as shown in FIG. 6, the glove spans between the movable instrument panel 30 and the fixed instrument panel 20. When the box 50 is formed, the depth direction length inside the glove box 50 can be changed, which is very convenient in practice.

  That is, an opening is formed in the vertical wall of the movable instrument panel 30, and this opening is covered with an openable / closable lid 51 having an opening / closing lock knob 52, and surrounds the opening on the back side of the movable instrument panel 30. Thus, the inner glove box 53 having a cylindrical wall surface is fixed to the movable instrument panel 30, while the fixed instrument panel 20 is in sliding contact with the outer peripheral surface of the inner glove box 53, and the end surface on the vehicle body front side The cylindrical outer glove box 54 closed with is fixed.

  In this way, by forming the single glove box 50 by the inner glove box 53 and the outer glove box 54, when the movable instrument panel 30 is at the position of the front Fr end of the vehicle body in the movable range, FIG. As shown in (a) and (b), the capacity of the glove box 50 is the minimum capacity V1, while when the movable instrument panel 30 is at the position of the vehicle body rear Rr end of the movable range, FIG. , (B), the capacity of the glove box 50 is the maximum capacity V2 (> V1).

  When the movable instrument panel 30 is located in the movable range between the front Fr end of the vehicle body and the rear Rr end of the vehicle body, the capacity of the glove box 50 is a capacity between the minimum capacity V1 and the maximum capacity V2. The capacity of 50 can be changed according to the displacement position of the movable instrument panel 30.

  Therefore, in the instrument panel 10 of the present embodiment in which the movable instrument panel 30 can be moved by a manual operation, not only can the movable instrument panel 30 be set at a desired front-rear position, but also the glove box 50. It is also possible to change the capacity of the battery, and usability can be improved.

  In addition, as a structure which makes the capacity | capacitance of the glove box 50 variable according to the front-back position of a movable instrument panel, it is not limited to the thing of the structure shown to FIGS.

  That is, in the glove box 50 shown in FIGS. 6 to 8, a part of the inner wall is overlapped with two wall members, the inner glove box 53 and the outer glove box 54, and the overlapped length is changed. For example, even when the movable instrument panel 30 is positioned at the front Fr end of the vehicle body within the movable range, there is an overlapping portion of the inner glove box 53 and the outer glove box 54. Without joining, the outer glove box 54 and the inner glove box 53 are joined by an expandable / contractible bellows member, and the expansion / contraction of the bellows member absorbs the movement of the movable instrument panel 30 and changes the capacity of the glovebox 50. Can be made.

  The instrument panel 10 of the above-described embodiment is configured by two large members, the fixed instrument panel 20 and the movable instrument panel 30, but the instrument panel structure according to the present invention is limited to such a form. For example, as shown in FIGS. 9 and 10, only a part of a conventional instrument panel (referred to as a fixed instrument panel 20 for convenience) is inflated by the operation of the airbag system 80. As a receiving surface that supports the airbag body 82 from below, it may protrude toward the vehicle body rear side Rr.

  That is, FIG. 9 shows that a part of the upper wall (sliding portion 60) of the fixed instrument panel 20 that includes the airbag main body 82 and is fixed to the vehicle body is slid to the vehicle body rear R by the operation of the airbag system 80. The upper surface 61 after the slide portion 60 is displaced is a receiving surface that supports the airbag body 82 from below, as shown in FIG. 9C. Yes.

  Also with the instrument panel configured in this manner, the upper surface 61 of the slide portion 60 that protrudes toward the rear of the vehicle body by the operation of the airbag system 80 is inflated as in the instrument panel 10 of the above-described embodiment. It functions as a receiving surface that supports the main body 82 from below, and the position, posture, and shape of the inflated airbag main body 82 can be stabilized as compared with those in which such a slide portion 60 does not exist.

  On the other hand, when the airbag system 80 is not in operation, the slide portion 60 does not protrude toward the vehicle body rear side Rr, so that the amount of protrusion to the vehicle body rear side Rr can be suppressed, and a large space in the vehicle interior can be secured. Can do.

  Therefore, it is possible to ensure both a large vehicle interior space and the stability of the airbag body 82.

  The slide portion 60 shown in FIG. 9 has a stopper 63 formed at the rear end of the slide direction, that is, the front Fr end of the vehicle body, to prevent the slide portion 60 from falling off the fixed instrument panel 20. .

  Further, the rear end surface of the sliding direction, that is, the front end surface 62 of the vehicle body is formed as an inclined surface having an upper end edge portion having an acute angle. Then, the inclined surface rides, and the entire slide portion 60 is slightly rotated so that the tip end in the slide direction faces the vehicle body Up (FIG. 9C).

  As a result, the upper surface 61 is in a posture toward the inflated airbag body 82, and the airbag body 82 can be supported more reliably from below, and the restraint of the airbag body 82 can be improved.

  Further, FIG. 10 shows that a part of the upper wall (rotating portion 70) of the fixed instrument panel 20 that includes the airbag main body 82 and is fixed to the vehicle body is the rear edge of the vehicle body rear Rr by the operation of the airbag system 80. The front Fr end edge of the vehicle body is displaced so as to be displaced upward around the hinge portion 73 (FIG. 10B), and the upper surface 72 after the rotational portion 70 is rotationally displaced (FIG. 10B). The lower surface before the rotational displacement shown in a) is a receiving surface that supports the airbag body 82 from below.

  Similarly to the instrument panel 10 of the above-described embodiment, the instrument panel configured as described above has an upper surface 72 after the rotational displacement of the rotating portion 70 protruding rearward of the vehicle body by the operation of the airbag system 80. Functions as a receiving surface for supporting the inflated airbag body 82 from below, and stabilizes the position, posture, and shape of the inflated airbag body 82 as compared with those without such a rotating portion 70. Can do.

  On the other hand, when the airbag system 80 is not in operation, the rotating portion 70 does not protrude from the vehicle body rearward Rr, so that the amount of protrusion to the vehicle body rearward Rr can be suppressed, and a large space in the vehicle interior is secured. be able to.

  Therefore, it is possible to ensure both a large vehicle interior space and the stability of the airbag body 82.

  Since the upper surface 71 before the rotational displacement has an arcuate convex surface in the vicinity of the hinge portion 73, the upper surface 72 as the receiving surface is swollen like the inclined surface in the slide portion 60 of FIG. The attitude toward the bag body 82 is achieved, the airbag body 82 can be supported more reliably from below, and the restraint of the airbag body 82 can be improved.
