  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 is a cross-sectional view showing one embodiment of a brake pedal fastening structure according to the present invention in a side view of a vehicle. FIG. 2 is an enlarged view of a portion X in FIG.

  As shown in FIG. 1, the dash panel 20 is separated from the front portion (typically, the engine compartment) of the vehicle body and the interior space. An instrument panel assembly 70 is disposed on the vehicle rear side of the dash panel 20. As shown in FIG. 1, the instrument panel assembly 70 includes a surface panel member 71 made of resin or the like and constituting a design surface (skin layer), and a pipe member having a circular cross section extending in the vehicle width direction from side to side. And a reinforcement panel (hereinafter referred to as “instrument panel R / F72”). A meter 74 and a cluster panel 75 for performing various displays, a steering mechanism 76, an air conditioner, and the like are attached to the instrument panel assembly 70.

  FIG. 3 is a perspective view when the instrument panel R / F 72 is viewed from the front side of the vehicle. A mounting bracket 78 for supporting the brake pedal assembly 30 is formed in the instrument panel R / F 72. The mounting bracket 78 is disposed corresponding to the brake pedal arrangement position in the vehicle width direction. The mounting bracket 78 may be formed, for example, by bending or punching a sheet metal, and may be attached to the instrument panel R / F 72 (pipe material) by welding or the like. Alternatively, the mounting bracket 78 may be formed integrally with the instrument panel R / F 72. Although not shown in FIG. 3, in the instrument panel R / F 72, various mounting brackets such as a steering column are similarly formed in addition to the mounting bracket 78.

  As shown in FIGS. 2 and 3, the mounting bracket 78 has a mounting surface 78 a (hereinafter referred to as “detaching bracket mounting surface 78 a”) to which a release bracket 36 of the brake pedal assembly 30 described later is fastened. The detachment bracket mounting surface 78a is a surface that is fitted and fastened to a first surface 36a of a later-described detachment bracket 36. Similar to the first surface 36a, the vehicle rear side is downward and the vehicle front side is upward in a side view. The normal direction is inclined in the direction of The technical significance of having such a normal direction will be described later with reference to FIG.

  The position of the detachable bracket mounting surface 78a in the vehicle front-rear direction is determined according to the configuration of the brake pedal assembly 30 (particularly, the mounting point of the detachable bracket 36), but normally the vehicle front side of the instrument panel R / F72. (See FIG. 1 etc.). Therefore, as shown in FIG. 3, the detachable bracket mounting surface 78 a of the mounting bracket 78 is constructed between the vehicle front side end portions of the left and right side surfaces 78 b extending from the instrument panel R / F 72 to the front of the vehicle. The side surface 78b is provided in a region / range where the strength and rigidity necessary for the mounting bracket 78 can be secured.

  As shown in FIGS. 2 and 3, a bolt hole 73 slightly larger than the shaft diameter of the fastening bolt 50 is formed in the detachment bracket mounting surface 78 a. A fastening bolt 50 (see FIG. 2) for fastening the release bracket 36 is obliquely upward from the rear side of the vehicle due to the inclination (normal direction) of the above-described release bracket mounting surface 78a. It is inserted toward. Note that the position of the bolt hole 73 in the release bracket mounting surface 78a depends on the configuration of the brake pedal assembly 30 (particularly, the mounting point of the release bracket 36), but in general, in front of the instrument panel R / F 72. In addition, the height is substantially the same in the vertical direction (see FIG. 1).

  A bottom surface 78c of the mounting bracket 78 extends toward the rear of the vehicle from the lower end of the detaching bracket mounting surface 78a. That is, the bottom surface 78c closes the lower side of the space defined by the separation bracket mounting surface 78a and the two side surfaces 78b. The bottom surface 78c of the mounting bracket 78 may be formed separately from the separation bracket mounting surface 78a and the side surface 78b, and may be fixed by welding or the like, or may be formed integrally. As shown in FIG. 1, the bottom surface 78c is inclined in such a direction that the rear side of the vehicle is downward and the front side of the vehicle is upward. That is, the mounting bracket 78 forms a bag-like space on the inner side that is inclined so that the rear side of the vehicle is downward and the front side of the vehicle is upward. The technical significance of the inclination of the bottom surface 78c will be described later in connection with FIGS.

  Referring again to FIG. 1, a brake pedal assembly 30 is disposed in an appropriate space near the passenger's feet. The brake pedal assembly 30 includes a brake pedal 32, a brake pedal support (pedal bracket) 34 that rotatably holds the brake pedal 32, and a release bracket 36.

  The brake pedal support 34 has a mounting portion 34 b that faces the dash panel 20. The side surface portion 34c is erected from the attachment portion 34b toward the rear of the vehicle, and a rotating shaft 32a of the brake pedal 32 is formed on the rear side of the vehicle. The brake pedal support 34 also integrally includes a release bracket fastening portion 35 to which the release bracket 36 is fastened.

  FIG. 4 is a perspective view showing an example of the separation bracket 36. The release bracket 36 is formed of, for example, a sheet metal and has an L-shaped cross section in a side view as shown in FIG. That is, the release bracket 36 is removably fastened to the first surface 36a fastened to the instrument panel R / F 72 (the mounting bracket 78 extending from the instrument panel R / F 72) and the release bracket fastening portion 35 of the brake pedal support 34. Two surfaces 36b. In the example shown in FIG. 4, an inclined surface 36 c that connects these two surfaces is formed between the first surface 36 a and the second surface 36 b. That is, the first surface 36a and the second surface 36b form an angle (about 90 degrees in this example) with the inclined surface 36c.

  The first surface 36a is a surface that is fastened in conformity with the detachable bracket mounting surface 78a of the mounting bracket 78 described above. In the normal state in which the brake pedal assembly 30 is attached to the vehicle (normal state in the sense that the vehicle body is not deformed due to a collision or the like), the rear side of the vehicle is downward when viewed from the side, like the release bracket attachment surface 78a. It has a normal direction inclined in a direction in which the front side of the vehicle is upward. The technical significance of having such a normal direction will be described later with reference to FIG.

  A bolt hole 37a (see FIG. 2) slightly larger than the shaft diameter of the fastening bolt 50 is formed in the first surface 36a. As shown in FIG. 4, a weld nut 52 corresponding to the bolt hole 37a is provided on the surface of the first surface 36a facing the vehicle front side in the assembled state of the vehicle. Due to the inclination (normal direction) of the first surface 36a described above, a fastening bolt 50 for fastening the release bracket 36 and the instrument panel R / F 72 is obliquely upward from the rear side of the vehicle. (See FIG. 1).

  As shown in FIG. 4, the second surface 36b is formed with a detachment hole 42 through which a bolt 40 (see FIG. 2, hereinafter referred to as “detachment bolt 40”) is detachably inserted. The detachment hole 42 extends in a groove shape along the vehicle front-rear direction from the vicinity of the substantially central portion of the second surface 36b, and extends to the inclined surface 36c. The width of the separation hole 42 (the width of the hole in the vehicle width direction) is determined corresponding to the shaft diameter of the separation bolt 40. The width of the detachment hole 42 is enlarged on the inclined surface 36c so that the head of the detachment bolt 40 (if the washer is provided, the washer and the head) can pass. That is, the separation hole 42 has a width corresponding to the shaft diameter of the separation bolt 40 on the second surface 36b, and a width and height corresponding to the diameter and height of the head of the separation bolt 40 on the inclined surface 36c. Have Unlike the present example, the first surface and the second surface are formed without using a substantially flat inclined surface (that is, the first surface and the second surface are formed by a relatively small bend R). ), A slot corresponding to the shaft diameter of the same bolt 40 is formed on the first surface, and a width and height corresponding to the diameter and height of the head of the separation bolt 40 are formed on the second surface. In addition, a bolt head passage hole that is continuous with the groove hole on the first surface may be formed.

  Referring back to FIG. 2, the release bracket fastening portion 35 of the brake pedal support 34 has an upper surface 34a (hereinafter referred to as “bracket holding surface 34a”) with which the second surface 36b is aligned. A bolt hole 34b through which the separation bolt 40 is inserted is formed.

  Since the brake pedal assembly 30 is configured, the release bracket 36 is fixed to the release bracket fastening portion 35 of the brake pedal support 34 by a release bolt 40 and a corresponding nut 41. At this time, as shown in FIG. 2, the separation bolts 40 are in a state where the second surface 36 b of the separation bracket 36 and the bracket holding surface 34 a of the separation bracket fastening portion 35 are aligned, and the respective separation holes 42 and bolt holes 34 b. Passed through. Then, a nut 41 is fastened to the screw portion of the separation bolt 40 protruding from the back side of the bracket holding surface 34a of the separation bracket fastening portion 35. The nut 41 may be a weld nut. In this fastened state, the detachment bolt 40 is located in the detachment hole 42 (elongate portion) in the second surface 36b of the detachment bracket 36, and is brought into contact with the seat surface around the detachment hole 42 in the second surface 36b (axial force). Be bound. Further, the detaching bracket 36 is sandwiched between the lower surface of the head of the detaching bolt 40 and the bracket holding surface 34 a of the detaching bracket fastening portion 35.

  Here, with reference to FIG. 5, the detachment operation / function of the detachment bracket 36 will be outlined. When an obstacle (for example, another vehicle) collides with the front part of the vehicle, the front part of the vehicle body is crushed. With the deformation of the front part of the vehicle at that time, the dash panel 20 and the brake pedal support 34 (detachment bracket fastening part 35) move to the vehicle rear side. That is, the brake pedal support 34 (integrated with the separation bracket fastening portion 35) moves relative to the instrument panel R / F 72 toward the vehicle rear side. At this time, the difference in relative displacement between the two members is not absorbed by the large deformation of the release bracket 36 attached to both members of the brake pedal support 34 and the instrument panel R / F 72, but in the above-described release hole 42. It is absorbed by the rearward movement of the separation bolt 40. That is, as shown in FIG. 5, the brake pedal support 34 moves to the vehicle rear side with respect to the mounting bracket 78 of the instrument panel R / F 72 together with the release bolt 40 by the movement of the release bolt 40 in the release hole 42 to the rear of the vehicle. . When the rearward movement amount of the brake pedal support 34 with respect to the instrument panel R / F 72 is further increased, the head of the release bolt 40 finally comes out of the widened release hole 42 in the inclined surface 36c of the release bracket 36. As shown in FIG. 5, the brake pedal support 34 is detached from the separation bolt 40. At this time, the vehicle rear end portion of the bracket holding surface 34a of the separation bracket fastening portion 35 collides with the inclined bottom surface 78c of the mounting bracket 78, and is dropped downward in the vertical direction (that is, the brake pedal support 34 after separation). Is corrected). Thereby, it can prevent appropriately that brake pedal support 34 after detachment falls toward a crew member's leg. As a result, the brake pedal 32 itself also moves downward, and the brake pedal 32 can be prevented from moving toward the passenger. As shown in FIG. 5, the vehicle rear end of the bracket holding surface 34 a of the detachable bracket fastening portion 35 is stuck into the bottom surface 78 c of the mounting bracket 78 and cannot be detached when colliding with the bottom surface 78 c of the mounting bracket 78. It has a round shape that is convex and not sharp so that it does not become.

  In the present invention, the detaching operation / function of the detaching bracket 36 is not particularly limited to the above. For example, the detaching operation may be realized by breaking or deforming the detaching bracket 36 or breaking a bolt. Good.

  Next, a method for assembling the instrument panel assembly 70 to the vehicle body and a method for assembling the brake pedal assembly 30 to the instrument panel assembly 70 in this line will be described with reference to FIG. Note that the following various types of assembly are performed by an operator getting on the floor of the vehicle body.

  The brake pedal assembly 30 and the instrument panel assembly 70 are first assembled from the brake pedal assembly 30. Note that the brake pedal assembly 30 is preassembled by a subline or a supplier.

  The assembly of the brake pedal assembly 30 to the vehicle body is primarily realized by fixing the mounting portion 34 b of the brake pedal support 34 of the brake pedal assembly 30 to the dash panel 20. The fastening and fixing method for the dash panel 20 may be arbitrary. For example, a brake booster (not shown) is disposed on the back side of the dash panel 20 (the side opposite to the side where the brake pedal support 34 exists). A collar (cylindrical member with a screw cut inside) may be inserted and screwed into a stud bolt protruding from the brake booster through the hole of the dash panel 20.

  After the fastening of the mounting portion 34b of the brake pedal support 34 is finished, the instrument panel assembly 70 is then assembled to the vehicle body. The assembly of the instrument panel assembly 70 is performed in a so-called modular state. That is, for example, various predetermined components (meter 74, cluster panel 75, steering mechanism 76, air conditioner, etc.) are mounted on the front panel member 71 and instrument panel R / F 72 in the sub-line, and the instrument panel assembly 70 in a module state. Is assembled to the car body in this line. This so-called instrument panel module mounting has very good work efficiency, and since various components can be assembled in advance in the sub-line, the assembly of the instrument panel assembly 70 in this line is greatly improved. To do.

  When the instrument panel assembly 70 is assembled to the vehicle body, the detachable bracket mounting surface 78a of the mounting bracket 78 (the vehicle) with respect to the first surface 36a (the vehicle rear side surface) of the detachable bracket 36 of the brake pedal support 34. In other words, the front side surface) is aligned, that is, the fastening bolt 50 between the release bolt 40 of the brake pedal support 34 and the mounting bracket 78 of the instrument panel R / F 72 can be fastened.

  In this state, the fastening bolt 50 between the release bolt 40 of the brake pedal support 34 and the mounting bracket 78 of the instrument panel R / F 72 is normally fastened at a relatively far position as shown in FIG. The tool is executed by a tool suitable for bolt tightening (in this example, an impact wrench 90 with an extension bar 92 attached).

  At this time, in this embodiment, as described above, the first surface 36a of the release bracket 36 is inclined obliquely downward toward the rear of the vehicle in a side view, so that the release bracket 36 is attached as shown in FIG. The bracket 78 can be fastened from diagonally below the vehicle. That is, in this embodiment, for example, the extension bar 92 of the impact wrench 90 can be fastened through the lower side in the vertical direction of the pipe material of the instrument panel R / F 72 as shown in FIG. In this case, the extension bar 92 of the impact wrench 90 does not interfere with any components of the instrument panel assembly 70 as shown in FIG. Therefore, according to the present embodiment, the instrument panel assembly 70 is completely modularized (that is, the meter 74, the cluster panel 75, and the like are assembled, and the wire connection by the harness 80 (see FIG. 1) is completed with a sub-sign. It is possible to assemble with this line.

  Here, as a configuration in contrast to the present embodiment, in the comparative example in which the first surface 36a of the separation bracket 36 is inclined obliquely upward toward the rear of the vehicle in a side view, as shown in FIG. It is necessary to fasten the bracket to the instrument panel assembly 70 from diagonally above and behind the vehicle. That is, in this comparative example, the extension bar 92 of the impact wrench 90 needs to be fastened through the vertical direction upper side of the pipe material of the instrument panel R / F 72 (through the opening on the upper side of the mounting bracket 78) as shown in FIG. There is. In this case, the extension bar 92 of the impact wrench 90 interferes with components such as the meter 74 and the cluster panel 75 of the instrument panel assembly 70 as shown in FIG. For this reason, in this comparative example, the instrument panel assembly 70 is assembled to the vehicle body without the meter 74 or the cluster panel 75 assembled, and then the fastening bracket 50 and the mounting bracket 78 are fastened by the fastening bolt 50. Therefore, it is necessary to assemble the meter 74 and the cluster panel 75 and to connect harnesses related thereto. That is, after the instrument panel assembly 70 is made into a complete module state, it cannot be assembled in this line, and the number of work steps on the floor of the vehicle body increases.

  On the other hand, according to the present embodiment, as described above, the detachable bracket can be fastened to the instrument panel assembly 70 from obliquely below the rear of the vehicle, thereby facilitating instrument panel modularization. The work process can be reduced and workability can be improved.

  Further, in this embodiment, as shown in FIG. 6, when the operator inserts the extension bar 92 of the impact wrench 90 into the internal space of the mounting bracket 78 as shown in FIG. 6, the bottom surface 78 c of the mounting bracket 78. , The fastening bolt 50 attached to the tip of the extension bar 92 can be easily guided to the bolt hole 73 of the detachable bracket attaching surface 78a of the attaching bracket 78. As described above, the attachment point of the release bracket 36 with respect to the attachment bracket 78 is located in front of the instrument panel R / F 72. Therefore, after the instrument panel assembly 70 is assembled, the operator has a relatively low field of view. It is necessary to fasten the separation bracket 36 and the mounting bracket 78 with the fastening bolt 50 in a bad state. For this reason, being able to guide the extension bar 92 of the impact wrench 90 while relying on the inclination of the bottom surface 78c of the mounting bracket 78 is very effective in work in such a poor visibility state.

  FIG. 8 is a view showing another embodiment (embodiment 2) according to the present invention in a vehicle side view. Constituent elements similar to those in the first embodiment are given the same reference numerals, and description thereof is omitted.

  In this embodiment, the first surface 36 a of the detachable bracket 36 is on the vehicle front side with respect to the mounting bracket 78, and the first surface 36 a of the detachable bracket 36 is on the vehicle rear side with respect to the mounting bracket 78. This is different from the first embodiment. That is, in the present embodiment, the L-shaped cross section defined by the first surface 36a and the second surface 36b of the detachment bracket 36 is opposite to that of the first embodiment. .

  FIG. 9 is a perspective view showing an example of the detachable bracket 36 that may be used in the second embodiment. Similarly, the first surface 36a of the release bracket 36 has a bolt hole 37a and a corresponding weld nut 52 (not visible because of the back side of the first surface 36a in FIG. 9), and the second surface 36b A separation hole 42 through which the separation bolt 40 is removably inserted is formed. As shown in FIG. 9, the separation hole 42 is formed in a cutout shape that opens on the rear side of the vehicle on the second surface 36 b. As a result, in the same manner as in the first embodiment described above, the brake pedal support 34 is moved by the release bolt 40 as the brake pedal support 34 moves toward the rear of the mounting bracket 78 with respect to the mounting bracket 78 during the deformation process of the vehicle front. The vehicle can be detached from the rear side.

  In the second embodiment, the attachment point of the detaching bracket 36 with respect to the mounting bracket 78 is located on the vehicle front side (the side farther from the operator) than the first embodiment described above. In the second embodiment, the inclination of the first surface 36a of the detachable bracket 36 and the corresponding detachable bracket mounting surface 78a of the mounting bracket 78 is the same as in the first embodiment. By configuring so as to be obliquely downward toward the rear of the vehicle, the detachable bracket 36 can be fastened to the instrument panel assembly 70 from obliquely below the rear of the vehicle. That is, in this embodiment, for example, the extension bar 92 of the impact wrench 90 can be fastened through the lower side in the vertical direction of the pipe material of the instrument panel R / F 72 as shown in FIG.

  The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above-described embodiments, and various modifications and substitutions can be made to the above-described embodiments without departing from the scope of the present invention. Can be added.

  For example, in the above-described embodiment, the configuration in which the number of the fastening bolts 50 is one is shown, but it is naturally possible to fasten the mounting bracket 78 and the detaching bracket 36 with two or more fastening bolts 50. Also in this case, the region (the first surface 36a of the detachable bracket 36 and the detachable bracket mounting surface 78a of the mounting bracket 78 corresponding thereto) forming the fastening points of the two or more fastening bolts 50 is inclined downward toward the rear of the vehicle. What is necessary is just to comprise.

  The first surface 36a of the release bracket 36 and the release bracket attachment surface 78a of the attachment bracket 78 corresponding to the first surface 36a do not necessarily have the inclination as described above over the entire surface. In the peripheral region of the bolt hole 73 and the bolt hole 37a), the above-described inclination may be provided.

  Further, in the above-described embodiment, the weld nut 52 is provided on the release bracket 36 and the fastening is realized by the fastening bolt 50. However, it is also possible to provide the weld bolt on the release bracket 36 and realize the fastening by the corresponding nut. It is.

  Further, in the above-described embodiment, in order to increase the efficiency of the assembly, the detachable bracket 36 can be fastened to the instrument panel constituent member assembled to the vehicle as the instrument panel assembly 70 from the obliquely lower rear side of the vehicle. It is configured as follows. However, the present invention is not limited to this, and other instrument panel constituent members that can be attached to the instrument panel assembly 70 assembled in the vehicle (instrument panel constituent members that do not constitute the instrument panel assembly 70). ), The detachable bracket 36 may be configured to be fastened from diagonally below the rear of the vehicle. For example, when the mounting bracket 78 is not included in the instrument panel assembly 70, the mounting bracket 78 is attached to the instrument panel assembly 70 after the instrument panel assembly 70 is assembled to the vehicle, and then the mounting bracket is mounted. It is good also as attaching the detachment bracket 36 to 78 from the vehicle back diagonally downward.
