Definitions
- the present invention relates to a reinforcement that connects right and left-side front pillars of a vehicle body in order to reinforce an instrument panel and the vehicle body and, more particularly, to a reinforcement that allows effective use of space.
- a reinforcement disclosed in Japanese Patent Application Laid-Open No. HEI 11-115550 has a rectangular closed-section portion for securing a strength and an open-section portion for retaining a wire harness .
- the reinforcement since the aforementioned reinforcement is provided with the closed-section portion and the open-section portion, the reinforcement has a problem of an increased size (increased diameter) as a whole.
- a characteristic thereof is that in a reinforcement of an instrument panel that connects left and right-side front pillars of a vehicle body, a section of at least a portion of the reinforcement has a generally letter-H type shape (generally letter-H shape) . Therefore, the reinforcement has opening portions, so that members and component parts , such as a vehicle functional component part-mounting member, a functional component part, a wire harness and the like, can be disposed and laid in the opening portions. Hence, the space occupied by the reinforcement (the external shape thereof) can be effectively used. Furthermore, since the section of the reinforcement is a generally letter-H shape, the reinforcement secures a necessary torsional rigidity while having a reduced sheet thickness .
- the reinforcement is formed integrally with at least one of a mounting member for mounting a vehicle functional component part, such as a steering column (assembly) , a passenger seat airbag (assembly) and the like, a vehicle functional component part, such as a striker of a glove box and the like, and a center brace, a reduction of the number of component parts can be accomplished. At the same time, since there is no need to separately secure such component parts by welding or the like, the production cost can be reduced.

- FIGURE 5B is a VB-VB sectional view of the reinforcement shown in FIGURE 3.
- a reinforcement 10 of an instrument panel shown in FIGURE 1 is a reinforcement member for reducing a damage (fall of a front pillar) that a vehicle body receives at the time of a side impact on a vehicle or the like.
- the reinforcement 10 has connecting portions 11, 12 in its two end portions in a direction of a length (a right-left direction with respect to the vehicle body), each of the connecting portions having a plurality of bolt holes.
- the connecting portion 11 and the connecting portion 12 are connected and secured to a left-side front pillar via a bracket that is not shown in the drawings and to a right-side pillar FP indicated by a virtual line, respectively, by means of bolts .
- the reinforcement may be secured to the front pillars by other means, for example welding, caulking, riveting or the like.
- the reinforcement 10 thus connects the right and left-side pillars.
- a section of the reinforcement 10 perpendicular to the direction of the length of the reinforcement 10 (a section taken on II-II in FIGURE 1) has a generally letter-H type shape as shown in FIGURE 2. That is, the reinforcement 10 has a configuration formed by disposing two generally identically-shaped thin sheets 10c, lOd (hereinafter, the thin sheet 10c will be referred to as "upper thin sheet 10c", and the thin sheet lOd as “lower thin sheet lOd", for convenience in description) substantially parallel to each other so as to face each other, and connecting the thin sheets at their center axes extending in a direction of the length of the sheets by a thin sheet lOe.
- the reinforcement 10 defines a pair of opening portions lOf, lOg that are open forward and rearward with respect to the vehicle, respectively.
- a center brace 13 extending downward from the lower thin sheet lOd is formed integrally with the lower thin sheet lOd in a substantially central portion of the reinforcement 10 in the direction of the length thereof.
- a lower end of the center brace 13 is formed so as to be bolted to a side surface of a floor tunnel portion FT formed in a front floor.
- the first steering support 14 which directly (or indirectly via another member) supports, on its lower surface side, a breakaway bracket 31a of the steering column assembly 31, is formed so that the first steering support 14 sandwiches the lower thin sheet lOd and so that an upper end of the first steering support 14 is positioned at a substantially central portion of the connecting thin sheet lOe so as not to close the opening portion lOg.
- the mounting member 16 for the passenger seat airbag assembly 32 is a member for housing and securing the passenger seat airbag assembly 32.
- the mounting member 16 has a generally rectangular parallelepiped shape whose upper side is open .
- the mounting member 16 is formed on an upper surface of the upper thin sheet 10c, at a position corresponding to a position of a passenger seat.
- a striker 17 of a glove box (a member having, at its distal end, a squared letter-U shaped member that engages with a hook of the glove box not shown in the drawing), that is, a vehicle functional component part, extends from a suitable portion of the lower thin sheet lOd corresponding to the passenger seat position, rearward and downward with respect to the vehicle.
- a wire harness 33 for the vehicle is laid in the instrument panel, and is connected to, for example, meters, an air- conditioner appliance and the like, or a center cluster panel (switches and the like, displays, etc.).
- the wire harness 33 is secured and laid in the direction of the length of the reinforcement 10, within the opening portion lOg of the reinforcement 10 (within the sectional shape of the reinforcement 10, that is, within an outer contour defined by the section) .
- the second steering support 15 may be provided with a hole or a cutout (not shown) penetrating the main plane of the second steering support 15, so that a wire harness or an air duct or the like may be arranged in the second opening portion lOf.
- the above-described reinforcement 10 (including the end portions 11, 12) is made of aluminum, magnesium alloy, or the like .
- the reinforcement 10 is formed integrally with the center brace 13, the first and second steering supports 14, 15, the mounting member 16, and the striker 17 of the glove box, by a die-cast method.
- the reinforcement 10 is connected between the right and left-side front pillars, thereby reinforcing a vehicle body construction . Furthermore, since the sectional shape of the reinforcement 10 is of a letter-H type, a torsional rigidity can be secured without a need to considerably increase the sheet thickness of the reinforcement 10. Thus, vibrations and noises produced in the vehicle body are reduced and, at the same time, the riding comfort also improves .
- the sectional shape of the reinforcement 10 is set to the letter-H type shape, a space (roomage) occupied by the reinforcement 10 can be effectively used. That is, in the foregoing embodiment, because the first and second steering supports 14, 15 are partially or entirely placed within the opening portions lOf, lOg defined by the upper thin sheet 10c, the lower thin sheet lOd and the connecting thin sheet lOe, the roomage of the opening portion lOg, that is, the space occupied by the external shape of the reinforcement 10, is effectively used.
- the wire harness 33 can be laid within the outer contour defined by a section of the reinforcement 10. This also makes effective use of the space occupied by the reinforcement 10.
- the path of the wire harness 33 becomes linear, so that occurrence of an unnecessary bending stress in the wire harness 33 is avoided and so that interference between the wire harness 33 and other component parts present within the instrument panel can be avoided.
- the mounting members for securing vehicle functional component parts such as steering column assembly 31, the passenger seat airbag assembly 32 and the like, vehicle functional component parts, such as the striker 17 of the glove box and the like, and the center brace 13 are formed integrally with the reinforcement by a die-cast method. Therefore, the number of component parts is reduced. Moreover, since these component parts do not need to be separately secured to the reinforcement by welding or the like, the production cost as a whole can be reduced.
- a reinforcement 20 of an instrument panel of the second embodiment has a configuration that is slightly different from the configuration of the reinforcement 10. That is, the reinforcement 20 has connecting portions 21, 22 in its two end portions in a direction of a length thereof, each of the connecting portions having a plurality of bolt holes.
- the connecting portion 21 and the connecting portion 22 are secured to a left-side front pillar and a right-side front pillar, respectively, by bolts, so that the reinforcement 20 connects the right and left-side front pillars, as in the reinforcement 10.
- Alternative securing methods and means can be used as described for the first embodiment.
- the shape of a section of the reinforcement 20 perpendicular to the direction of the length thereof at any site is a generally letter-H type shape
- the sectional shape of a first portion of the reinforcement 20 between the connecting portion 21 and a center brace 23 is slightly different from the sectional shape of a second portion between the center brace 23 and the connecting portion 22. That is, the section of the first portion (a section taken on VA-VA in FIGURE 3) has a letter-H type shape that is the same shape as in the reinforcement 10, as shown in FIGURE 5A.
- the section of the second portion (a section taken on VB-VB in FIGURE 3 ) has a generally letter-H type shape, as shown in FIGURE 5B, in which upper and lower thin sheets 20c, 20i extend further leftward in the drawing (forward with respect to a vehicle) than those in the first portion, and a connecting thin sheet 20e extends further downward in the drawing (downward with respect to the vehicle) than that in the first portion, and thus the width and the height are increased in comparison with the first portion.
- the reinforcement 20 is formed integrally with the center brace 23, first and second steering supports 24, 25, etc.
- the first steering support 24 is formed on a upper position in the lower thin sheet 20d, and is formed so that a distance LI between an upper end surface of the steering support 24 and a lower surface of the upper thin sheet 20c substantially equals a distance L2 between an upper surface of the lower thin sheet 20d and the lower surface of the upper thin sheet 20c in the first portion.
- a plurality of generally rectangular cutouts 26 are formed in the upper thin sheet 20c and the lower thin sheet 20d of the reinforcement 20.
- the cutouts 26 are portions through which a main line and branch lines of a wire harness 33 are passed when the wire harness 33 is laid in an opening portion 20g of the reinforcement 20.
- the cutouts 26 function to allow the main line and the branch lines to be oriented in adequate directions. Similar cutouts can be provided as with the first embodiment.
- the above-described reinforcement 20 (including the end portions 21, 22) is made of aluminum, magnesium alloy, or the like, as in the reinforcement 10.
- the reinforcement 20 is formed integrally with the center brace 23 , the first and second steering supports 24, 25, and the like, by a die-cast method.
- the second embodiment achieves the advantages of the first embodiment.
- the rigidity of the second portion intended also to reduce steering vibrations is increased. Therefore, a more efficient weight distribution can be achieved, and a weight reduction as a whole is possible.
- the first steering support 24 in the second portion is formed so as not to close the opening portion 20g, so that a layout path of the wire harness is secured.
- the wire harness 33 can be linearly laid substantially throughout the length of the reinforcement 20, thereby achieving an advantage of not giving an unnecessary stress to the wire harness 33 and an advantage of shortening the wire harness 33.
- the second steering support 25 may also be provided with a hole or cutout penetrating the main plane thereof, thus not closing the second opening portion 20f.
- the sectional shape of the reinforcement is a generally letter-H type shape, and therefore, the reinforcement has a construction wherein other component parts or the like can be disposed within the outer contour defined by a section of the reinforcement (within a section) , so that the space can be effectively used, and wherein a necessary torsional rigidity can be secure without a need to considerably increase the sheet thickness.
- the reinforcements 10, 20 are formed by a die-cast method, the reinforcement may also be formed so as to have a letter-H-shaped section by an extrusion forming method, a technique in which a group of squared-letter-U-shaped iron members are bonded together, etc.
- the reinforcements 10, 20 are secured to the front pillars so that the opening portions lOf , lOg, 20f , 20g of the reinforcements 10, 20 face forward and rearward with respect to the vehicle, this construction is not restrictive, but the reinforcement may also be secured so that the opening portions face upward and downward or in diagonal directions with respect to the vehicle.
- each reinforcement 10 , 20 is mounted to the vehicle body before the wire harness 33 and the like are mounted, the invention is not limited by the embodiments . The invention is also applicable to a case where the wire harness 33, an airbag, a steering column, an instrument panel and the like are mounted to the reinforcement 10, 20 to form an assembly (instrument panel module) and the assembly is mounted to a vehicle body.
- a reinforcement 10 is connected between right and left-side front pillars, and reinforces an instrument panel.
- a section of the reinforcement 10 has a letter-H type shape.
- the reinforcement 10 is formed integrally with a center brace 13, the first and second steering supports 14, 15, a passenger seat-side airbag-securing member 16, a striker 17 of a glove box, and the like, by a die-cast method, so that the number of component parts and the production cost can be reduced.
