Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a collision safety device for a vehicle, which prevents a member disposed near the knee of an occupant from coming into contact with the knee during a vehicle collision.

[0002]

2. Description of the Related Art As shown in FIG.
A main column 13 is fixed to a front frame 11 and a front mount rail 12 which are connected to each other vertically. 24 and 26, a clutch master back 14 and a brake master back 15 are connected to the main pillar 13, and a clutch pedal support bracket 2a and a brake pedal support bracket for supporting the clutch pedal 23 and the brake pedal 24 are provided. 3a is fixed. Note that a clutch master cylinder 16 and a brake master cylinder 17 are disposed on the clutch master back 14 and the brake master back 15, respectively, protruding rearward. On the other hand, a steering support bracket 21 is connected to the rear end of the reinforcement that reinforces an unillustrated instrument panel. The steering support bracket 21 is attached to the floor panel 28.
The lower part is fixed to. The steering support bracket 21 holds the steering shaft 29, and the steering cowl 30 and the like are attached.

An occupant in a normal driving posture with the sole 20 in contact with the floor panel 28 is arranged with the steering cowl 30 and the like sandwiched between the two legs 31, 31 as shown by the two-dot chain line in FIG. Both knees 32 are connected to the clutch master cylinder 16 and the brake master cylinder 17.
And are arranged at positions facing each other with an appropriate space therebetween. In addition, the distal ends of the clutch pedal support bracket 2a and the brake pedal support bracket 3a are disposed with an appropriate gap from the front panel 22 during normal running.

[0004]

As described above, a gap is formed between the front panel 22 and the clutch pedal support bracket 2a and the brake pedal support bracket 3a, as shown in FIGS. 25 and 26. In the event of a collision, the front panel 22 is deformed from the position indicated by the two-dot chain line to the position indicated by the solid line. Therefore, the front panel 22 is hit by the clutch pedal support bracket 2a and the brake pedal support bracket 3a. The occupant also moves forward due to the inertial force at the time of the collision. As a result, there is a problem that the rear ends of the clutch master cylinder 16 and the brake master cylinder 17 hit the knee 32 and the knee 32 is damaged.

In order to solve the above problems, various types of collision safety devices have been disclosed. For example, Shokai 6
JP-A-3-58071 and JP-A-7-25329 are mentioned. "Supporting device for steering column in cab-over type vehicle" disclosed in Japanese Utility Model Laid-Open No. 63-58071.
Arranges a reinforcement (6) having a closed cross section having an inclined surface close to the rear end of the brake device (3), and moves the brake device (3) along the inclined surface of the reinforcement (6) at the time of collision. To prevent the knee and the like from interfering with the brake device (3). Japanese Unexamined Patent Publication No. 7-25329 discloses a "vehicle booster mounting structure" in which the lower end of a steering column (8) is swingable with a joint (23) as a fulcrum. This prevents the steering column (8) from hitting the knee or the like due to the column (8) swinging forward.

[0006] All of the above-mentioned known techniques are effective in protecting the knee in the event of a collision, but none of the above-mentioned techniques does not cause a lateral displacement between the clutch device or the brake device and the knee in the event of a collision. Depending on the distance between the device and the knee and the knee, there is a possibility that both will interfere or collide. Therefore, there is a problem that the knee cannot be completely protected. In addition, both have a rather complicated structure, and are more expensive than the present invention.

The present invention has been made in view of the above circumstances, and uses relatively simple means to shift the clutch device side or the brake device side to the right or left in the event of a collision, or to reduce the interference between them and the knee. It is an object of the present invention to provide a vehicle collision safety device that reliably prevents a collision and ensures occupant safety.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention forms a cab framework provided at the center of the front surface of the cab and connected to the upper side of the front panel across the vehicle width direction. A front frame, a front mount rail provided at a lower front part of the cab across the vehicle width direction and connected to a lower side of the front panel and a floor panel to form a skeleton of the cab; And a main pillar fixed to the upper end and disposed to face the front panel, a pedal bracket fixed to a center portion of the main pillar and fixed to a clutch master back and a brake master back at both ends protruding left and right, Clutch pedal support provided at the both ends of the pedal bracket to support a clutch pedal and a brake pedal A bracket and a brake pedal support bracket, and a steering support bracket for connecting an instrument panel connected to the front frame side to a rear end side of the reinforcement for reinforcing and supporting the instrument panel and connecting to the floor panel to hold a steering cowl and the like. A safety device for protecting an occupant's knee around a collision of a cab of a vehicle provided with each element, wherein the clutch pedal support bracket and the brake pedal support bracket are connected to or integrally formed with the both ends of the pedal bracket. However, a collision surface that first comes into contact with the front panel at the time of a collision is provided at a position of the front end portion most protruding toward the front panel side, and at a position of the front end portion most distant from the center of the pedal bracket. The pedal brake The packet constitutes a collision safety device for a vehicle master backplate thin to be stretched by an appropriate tension between the two ends, which are bridged. More specifically, the clutch pedal support bracket and the brake pedal support bracket are formed of separate members in which a plate material is formed into a U-shape and the open side is fixed to both ends of the pedal bracket. A collision safety device for a vehicle, wherein a surface and an inclined surface inclined downward from the collision surface toward the center of the pedal bracket are formed. Further, the clutch pedal support bracket and the brake pedal support bracket are formed of a support bracket plate material formed by projecting left and right ends of both ends of the pedal bracket toward the front panel side and a reinforcing plate material for reinforcing the support bracket plate material. A collision safety device for a vehicle, wherein the collision surface is formed at a protruding end of the support bracket plate material. Further, the collision safety device for a vehicle is characterized in that the collision surface is formed on a protruding end of a separate arm member fixed to the distal ends of the clutch pedal support bracket and the brake pedal support bracket. Further, the collision surface is formed of an arcuate surface, and a low rigid portion that can be bent and deformed by a bending load is formed at a boundary portion between a center portion and both end portions of the pedal bracket. Further, the present invention is characterized by a collision safety device for a vehicle in which an appropriately rigid stay is installed between a central portion of a master back plate installed on the pedal bracket and the steering support bracket.

During normal operation, a collision surface formed on the protruding end of the clutch pedal support bracket or the brake pedal support bracket is arranged at an appropriate distance from the front panel. However, at the time of a collision, the collision surface first contacts the front panel. The clutch pedal support bracket and the brake pedal support bracket are provided so as to be connected to both ends of a pedal bracket having a central portion fixed to the main pillar, and the collision surface is formed at a portion farthest from the central portion of the pedal bracket. You. The central portion of the pedal bracket has high rigidity because it is fixed to the main pillar, but the boundary between the central portion and both ends has low rigidity. Since the master back plate is stretched over the pedal bracket, the boundary portion is not deformed during normal running even if the boundary portion has low rigidity. However, at the time of a collision, a collision force acts on a collision surface located farthest from the center of the pedal bracket, so that both ends of the pedal bracket bend about the boundary even if there is a master back plate.
In particular, when a low-rigidity portion is formed at this boundary portion, it is easily bent.

On the other hand, since the clutch master back and the brake master back are connected to both ends of the pedal bracket, the clutch master back and the brake master cylinder also move with the bending of both ends, and the clutch master cylinder and the brake master cylinder are moved to the rear end. To the inside (toward the center). Therefore, interference between the rear end of the clutch master cylinder or the brake master cylinder and the knee is eliminated, and collision between the knee and the clutch master cylinder or the like is prevented even if the occupant moves forward. By making the collision surface arc-shaped, bending of both ends of the pedal bracket via the clutch pedal support bracket and the brake pedal support bracket is performed quickly and smoothly. In addition, by providing the stay between the central portion of the master back plate and the steering support bracket, the rigidity of the central portion of the pedal bracket is improved, and the bending deformation of both ends is more easily performed.

[0011]

Embodiments of the present invention will be described below in detail with reference to the drawings. First, a schematic structure of a cab steering, a clutch device, and a brake device around a cab of a vehicle provided with main components of the present invention will be described with reference to FIGS.

On the other hand, an instrument panel 18 is connected to the front frame 11 side as shown by a two-dot chain line in FIG.
And the steering support bracket 21.
The steering support bracket 21 holds the steering shaft 29 and attaches the steering cowl 30 and the like. The lower end of the steering support bracket 21 is fixed to the floor panel 28. As shown in FIG. 2, the legs 31 of the occupant are arranged with the steering cowl 30 and the like in between.

As shown in FIGS. 2 to 5, a pedal bracket 1, which is one of the main components of the present invention, has a convex portion 26 which is bent in a U-shape at the center thereof and which is stretched right and left from its base end side. The end portions are reinforced by flanges 33. In the following, for convenience of explanation, the left end 27a is the left end 27a and the right end 2 is the right end 2a.
7b.

A master back plate 4 made of a flat thin plate member is stretched and fixed between the left end 27a and the right end 27b of the pedal bracket 1. The master back plate 4 holds the posture of the convex portion 26 and the both end portions 27 and functions to prevent deformation of the pedal bracket 1 due to an acting force normally acting on the pedal bracket 1.

As shown in FIG. 4, a clutch master back 14 and a brake master back 15 are fixed to the left and right ends 27a and 27b of the pedal bracket 1, respectively, as shown in FIG. As shown in FIGS. 2, 3 and 5, etc., the clutch pedal support bracket 2 and the brake pedal support bracket 3, which are one of the main components of the present invention, are provided in front of the left end 27a and the right end 27b. The base ends are each fixed.

The clutch master back 14 and the brake master back 15 are provided with a clutch master cylinder 16 and a brake master cylinder 17 projecting rearward. Also, the clutch pedal support bracket 2 and the brake pedal support bracket 3
The rotating parts of the clutch pedal 23 and the brake pedal 24 are respectively connected to the protruding inside. As shown in FIGS. 3 and 4, a clutch switch bracket 34 and a brake switch bracket 35 are fixed below the pedal bracket 1, respectively. A switch (not shown) for detecting the operation of the clutch pedal 23 and the brake pedal 24 is provided between the clutch pedal 23 and the brake pedal 24.

As shown in FIG. 5, the pedal bracket 1 has a projection 26 at the center thereof fitted into the
The left end 27a and the right end 27b of the both ends 27 are arranged so as to protrude from the left and right ends of the main column 13. As shown in the figure, the base ends of the clutch pedal support bracket 2 and the brake pedal support bracket 3 are fixed to the left end 27a and the right end 27b by welding or the like. Further, as described above, the master back plate 4 is stretched between the left end portion 27a and the right end portion 27b, and is fixed thereto by welding or the like.

As shown in FIG. 5, when the clutch and the brake are operated during normal vehicle running, a force shown by an arrow P acts on the left end portion 27a and the right end portion 27b of the pedal bracket 1, and the pedal bracket 1 Main pillar 13
Bends about the virtual rotation fulcrum points a and b. However, the master back plate 4
This bending deformation is prevented by the tension of, and the state of FIG. 5 is maintained.

Next, the shapes of the clutch pedal support bracket 2 and the brake pedal support bracket 3 will be described. Since both are substantially symmetrical, only one brake pedal support bracket 3 will be described. As shown in FIGS. 5 and 6, etc., the brake pedal support bracket 3 is formed by bending a single plate into a U-shape, and the flange 36 at the base end thereof is fixed to the right end 27b as described above. Is done. A collision surface 8 is formed at the tip of the right end protruding portion in FIG. 6, and an inclined surface 25 that is inclined downward from the collision surface 8 toward the left end is formed. FIG.
As shown in FIG. 5, the collision surface 8 is formed at a position farthest from the projection 26 at the center of the pedal bracket 1, and is formed so as to protrude most. The collision surface 8 is formed as an arcuate surface as shown.

As shown in FIGS. 1 and 2, during normal vehicle running, the collision surface 8 of the clutch pedal support bracket 2 and the brake pedal support bracket 3 is arranged with an appropriate gap from the front panel 22. No contact occurs between the two. Also, as shown in FIG.
The knee 32 of the leg 31 is located at a position opposite to the rear end of the clutch master cylinder 16 or the brake master cylinder 17, but is arranged at an appropriate interval.

FIG. 7 shows the deformed state of each part at the time of a collision and the relative positions of the clutch master cylinder 16 and the brake master cylinder 17 and the occupant's knee 32 during the deformation. As shown in FIGS. 7 and 8, at the time of collision, the front panel 22 at the position indicated by the two-dot chain line is pressed by the input at the time of collision and moves to the position indicated by the solid line.
2, the collision surfaces 8, 8 of the clutch pedal support bracket 2 and the brake pedal support bracket 3 abut against the front panel 22, and the collision surface 8 is pressed. FIG.
As shown in the figure, the contact points between the collision surfaces 8, 8 and the front panel 22 are set at point c (clutch side) and point d (brake side).
The inputs Fc and Fd at the time of collision act on the position. Here, the crack pedal support bracket 2 and the brake pedal support bracket 3 are welded to the contact portions of the pedal bracket 1 together with the master back plate 4 and are fixed by the master backs 14 and 15 and the nuts. In this state, the portion is a stronger member than the single state of the crack pedal support bracket 2 and the brake pedal support bracket 3. For this reason, the inputs Fc and Fd at the time of the collision act on the virtual rotation fulcrum points a and b, respectively, to exert moments for rotating the corresponding parts integrally in the Fc ₁ and Fd ₁ directions, respectively. On the other hand, the master back plate 4 receives a buckling force and a bending force unlike the pulling force normally applied when the pedal is operated, and the plate 4 exerts a certain degree of drag against the moments Fc ₁ and Fd ₁ described above. FIG. 8
While deforming the master back plate 4, the left end portion 27a and the right end portion 27b are rotationally deformed as shown in FIG. Therefore, the clutch pedal support bracket 2 and the brake pedal support bracket 3 are inclined outward as shown in FIGS. Therefore, as shown in FIG. 7, the clutch master back 14 and the brake master back 15 tilt inward, and the rear ends of the clutch master cylinder 16 and the brake master cylinder 17 move inward as indicated by the arrow R.

As shown in FIG. 7, the occupant's leg 31 also advances due to the collision, and the knee 32 also advances to a position beyond the steering support bracket 21, but the clutch master cylinder 16 and the brake master cylinder 17 move as described above. Since the incline is inclined inward, the knee 32 has a phase difference with the tip portions of both master cylinders 16 and 17 and is reliably protected, so that safety in a collision is ensured.

FIGS. 9 to 11 show several examples of the low-rigidity portion 7 provided on the pedal bracket 1. FIG. The low-rigidity portion 7 is provided at the boundary between the convex portion 26 and both ends 27 of the pedal bracket 1, and more specifically, is provided near the virtual rotation fulcrum points a and b. The low-rigidity portion 7 reduces the rigidity in the vicinity of the points a and b so that the bending deformation of the both ends 27 at the time of a collision can be performed more reliably, quickly, and easily. FIG. 9 shows a notch 37 formed by cutting a part of the flange 33 of the pedal bracket 1. FIG. 10 shows a case in which a notch 38 in the shape of a through-hole is formed to have low rigidity. FIG. 11 shows a hinge 39 provided to facilitate bending. Of course, a structure having a structure other than that described above is also used as the low rigidity portion 7.

FIG. 12 shows another embodiment of the present invention. In the above-described embodiment, the clutch pedal support bracket 2 and the brake pedal support bracket 3 are provided with the collision surface 8 and the inclined surface 25 on the tip side. The inclined surface 25 allows only the collision surface 8 to abut on the front panel 22 to ensure that the clutch pedal support bracket 2 and the brake pedal support bracket 3 are deformed. A corresponding bending mold is required. Also,
If the collision surface 8 is deformed by the impact force and the arcuate surface is not maintained, the sliding between the collision surface 8 and the front panel 22 may not be performed smoothly, and the deformation may be uncertain. This example solves these problems.
In this example, the clutch pedal support bracket and the brake pedal support bracket are formed from flat ones having no inclined surface on the distal end side to facilitate processing at the time of press forming, and to which an arm member 5 as a separate product is fixed instead. It is. The arm member 5 is a pedal bracket 1 of a clutch pedal support bracket or a brake pedal support bracket.
12 is welded at the most distant position from the central part of FIG.
(A) is formed of a U-shaped rod-shaped member, and a collision surface 8 is formed as an arc-shaped surface at a protruding end thereof. In this example, the arm member 5 has a shape that is inclined outward.
Although the same function as that of the inclined surface 25 of the above-described embodiment is performed, the inclination may be omitted. According to this embodiment, the same effects as those of the other embodiments can be obtained.

FIGS. 13 to 17 show still another embodiment of the present invention. This embodiment is characterized in that a stay 6 is provided, and other portions are the same as those of the embodiment shown in FIG. Stay 6
Is provided between the central portion of the master back plate 4 which is stretched and fixed to the pedal bracket 1 and the steering support bracket 21. The steering support bracket 21 is supported by the reinforce 19 (FIG. 1) as described above, and is made of a rigid material that is relatively not deformed even in the event of a collision. The stay 6 is made of a plate member in this embodiment, but is made of a material having higher rigidity than the master back plate 4.

FIGS. 18 and 19 show the state at the time of collision in this embodiment. In general, the input at the time of a collision causes the entire brake and clutch system to move and cause a movement to reduce the distance between the steering system and the steering system. While increasing the strength of the master back plate 4 against buckling and bending in order to improve the operational feeling during operation, the movement at the time of the collision causes the stay 6 to move the joint with the plate 4 in reverse to the entire movement. By pushing in the direction, the plate 4 can be deformed, and the conflicting demands of making the plate 4 easy to deform while increasing the strength can be achieved. Thereby, the left end 2 of the pedal bracket 1
7a and the right end 27b are more reliably deformed at the time of a collision, and the safety protection effect of the knee 32 can be improved.

FIGS. 20 and 21 show still another embodiment of the present invention, and FIG. 22 shows a state of a collision in that case. In this example, the shapes of the clutch pedal support bracket and the brake pedal support bracket are different from those described above, but the other shapes are the same as those shown in FIG. In this example, as shown in FIG. 21, the pedal bracket 1a is formed by a central projection 26, a left end 27a and a right end 27b, and support bracket plates 9, 9 protruding forward from both end edges. Become. That is, the support bracket plates 9, 9 project from the left end portion 27a and the right end portion 27b toward the front panel 22 and constitute a part of the clutch pedal support bracket 2 and the brake pedal support bracket 3 described above. . As shown in FIGS. 20 and 21, a reinforcing plate 10 for reinforcing the support bracket 9 is fixed inside the support bracket plate 9. The reinforcing plate 10 is fixed to the left end 27a and the right end 27b.

A flange 33 formed on the pedal bracket 1 is formed on the support bracket plate 9 as it is, and a corner portion 40 at the tip of the flange 33 forms the collision surface 8. Therefore, the tip of the reinforcing plate 10 is located at the corner 40
It is located at the position retracted from. The corner portion 40 of the support bracket plate 9 is located farthest from the convex portion 26 at the center of the pedal bracket 1, and the same effects as in the above-described embodiment can be achieved. FIG. 22 shows a state at the time of a collision in this example, and it can be seen that interference between the knee 32 and the clutch master cylinder 16 and the brake master cylinder 17 is prevented.
