Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a floor structure below a vehicle pedal, and more particularly to a floor structure below a vehicle pedal on which an occupant foot is placed when the vehicle is traveling.
[0002]
[Prior art]
Conventionally, an example of a floor structure below a vehicle pedal on which an occupant's foot is placed when the vehicle travels is disclosed in JIII Journal of Technical Disclosure No. 90-18490.
[0003]
As shown in FIG. 8 , in the floor structure below the vehicle pedal, the accelerator pedal 100 is positioned below the arch 102A of the shoe 102 so that the shoe 102 contacts the accelerator pedal 100 as the vehicle pedal. A footrest 106 is disposed on the floor surface 104. As a result, the bend angle θ of the dripper's ankle 108 is reduced by the footrest 106, and the load on the ankle 108 can be reduced during long-time driving. Further, in a vehicle having such a structure in which the vicinity of the arch 102A of the shoe 102 is always in contact with the footrest 106 so that the movement of the heel 102B to the front of the vehicle is always restricted, the floor surface rises and deforms at the time of collision. Even if it occurs, the footrest 106 restricts forward movement of the collar 102B. For this reason, the change in the bending angle θ of the dripper's ankle 108 becomes small.
[0004]
[Problems to be solved by the invention]
However, in this floor structure below the vehicle pedal, the footrest 106 is always in contact with the arch 102A near the shoe 102 in the normal running state. As a result, as shown by a two-dot chain line in FIG. 8 , when the accelerator pedal 100 is depressed, the saddle 102B is lifted around the contact point P between the footrest 106 and the arch 102A and becomes unstable. . In addition, since the area around the arch 102A is always in contact with the footrest 106, a sense of discomfort may be felt when the accelerator pedal is operated.
[0005]
In consideration of the above facts, the present invention can stabilize the heel when the pedal is operated, and can control the movement of the heel when the occupant's heel moves a predetermined distance forward. Is the purpose.
[0006]
[Means for Solving the Problems]
The floor structure under the vehicle pedal according to the first aspect of the present invention is disposed on the floor panel below the vehicle pedal, and when the heel of the passenger foot moves forward by a predetermined distance in the event of a collision ,踵 movement restriction means made of a metal plate that restricts movement to
A mounting bolt for fixing the rod movement restricting means to the floor panel ;
A nut screwed onto the mounting bolt;
A carpet disposed in a vehicle interior side of the floor panel and the eaves movement restricting means;
And the heel movement restricting means is disposed at a position spaced a predetermined distance from a contact point between the heel of the occupant foot and the top surface of the carpet, which steps on the vehicle pedal.
[0007]
Therefore, in the normal running state, the heel of the occupant foot is not in contact with the heel movement restricting means made of a metal plate fixed to the floor panel by the mounting bolt and the nut screwed to the mounting bolt, and the occupant foot is not The bag can be swung forward about the contact point between the bag, the floor panel, and the upper surface of the carpet disposed on the side of the vehicle interior of the bag movement restricting means , and the bag does not float from the upper surface of the carpet . As a result, the heel can be stabilized when the pedal is operated. Further, when the accelerator pedal moves to the forward depression position, the movement of the occupant foot is not restricted by the heel movement restricting means. Further, since the saddle movement restricting means can ensure a predetermined rigidity and the saddle movement restricting means can have a thin plate structure, the floor space can be effectively utilized. Further, the position of the attachment portion is not limited to the front end of the floor panel in the vehicle front-rear direction.
[0008]
On the other hand, when the occupant foot moves forward by a predetermined distance with respect to the floor surface at the time of a collision such as a frontal collision, the heel movement restriction means restricts the movement of the heel forward relative to the floor surface. As a result, even when the front floor surface rises and deforms, the toe of the occupant foot does not abruptly contact the front floor surface, so the angle of the occupant foot relative to the horizontal plane, in other words, the bending angle of the ankle Can be prevented from changing suddenly.
[0009]
According to a second aspect of the present invention, in the floor structure below the vehicle pedal according to the first aspect, the heel movement restricting means is an energy for reducing the contact force between the metal plate, the occupant foot and the upper surface of the carpet. And an absorbent material.
[0010]
Therefore, in addition to the contents of claim 1, in the event of a collision, the heel movement restricting means not only restricts the movement of the heel forward relative to the upper surface of the carpet, but also the occupant's foot is located on the upper surface of the carpet in front by the energy absorbing material. The impact at the time of abutting can be reduced.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
A first embodiment of a floor structure below a vehicle pedal according to the present invention will be described with reference to FIGS.
[0012]
In the figure, the arrow UP indicates the upward direction of the vehicle, and the arrow FR in the figure indicates the forward direction of the vehicle.
[0013]
As shown in FIG. 4, in the present embodiment, the lower part of the front end of the passenger compartment is constituted by a floor panel 10 and a dash panel 12 that rises diagonally forward from the front end of the floor panel 10. A metal bracket 16 having a predetermined width as a movement restricting means is disposed in a portion adjacent to the dash panel 12. A lower portion of the bracket 16 is an attachment portion 16A, and the attachment portion 16A is fixed to the floor panel 10 by fixing means such as a pair of left and right attachment bolts 18 or the like.
[0014]
As shown in FIG. 1, the mounting bolt 18 is screwed into a nut 20 disposed on the back surface 10 </ b> B of the floor panel 10. Further, the upper portion of the bracket 16 is a saddle movement restricting portion 16B, and this saddle movement restricting portion 16B rises obliquely forward with a gap 17 of a predetermined width between the dash panel 12 and obliquely rearward in a side view. The shape is slightly bulged into a circular arc. Note that a carpet 24 is disposed on the side of the vehicle interior of the floor panel 10, and the bracket 16 is disposed between the floor panel 10 and the carpet 24.
[0015]
An accelerator pedal 28 as a vehicle pedal is disposed above the bracket 16, and the heel movement restricting portion 16 </ b> B of the bracket 16 includes a heel 30 </ b> A of an occupant foot 30 that steps on the accelerator pedal 28, and an upper surface of the carpet 24. (Floor surface) 25 is disposed at a position spaced a predetermined distance forward from the contact P with the floor. Accordingly, when the accelerator pedal 28 is depressed, the toe 30B of the passenger foot 30 swings forward (in the direction of arrow B in FIG. 1) around the contact P, and the accelerator pedal 28 is moved from the position indicated by the solid line in FIG. When moving to the step-down position of the front two-dot chain line, the movement of the occupant foot 30 is not restricted by the bracket 16.
[0016]
Next, the operation of this embodiment will be described.
[0017]
In the present embodiment, as shown in FIG. 1, the heel 30 </ b> A of the occupant foot 30 is spaced behind the bracket 16 in the normal running state. As a result, as shown by a two-dot chain line in FIG. 1, when the accelerator pedal 28 is depressed, the toe 30B of the occupant foot 30 swings forward (in the direction of arrow B in FIG. 1) about the contact P. However, at this time, the movement of the occupant foot 30 is not restricted by the bracket 16. For this reason, since the heel 30A of the passenger foot 30 does not float from the floor surface 25, the heel 30A can be stabilized when the accelerator pedal is operated, and a sense of incongruity is not felt.
[0018]
On the other hand, as shown in FIG. 2, when the occupant foot 30 moves forward (in the direction of arrow A in FIG. 2) with respect to the floor surface 24 during a frontal collision or the like, the heel 30 </ b> A It contacts the movement restricting portion 16B via the carpet 24. For this reason, the bracket 16 restricts the forward movement of the flange 30 </ b> A with respect to the floor surface 25. As a result, as shown in FIG. 3, even when the dash panel 12 rises and deforms, the toe 30 </ b> B of the occupant foot 30 does not abruptly contact the dash panel 12 via the accelerator pedal 28 and the carpet 24. . For this reason, it is possible to prevent the angle θ1 of the heel 30A with respect to the horizontal plane L, in other words, the bending angle θ2 of the ankle 30C from changing suddenly.
[0019]
Further, in the present embodiment, since the metal bracket 16 is used as the saddle movement restricting means, a predetermined rigidity is ensured and the saddle movement restricting means can be made into a thin plate structure, so that the floor space can be effectively utilized. Furthermore, since the metal bracket 16 is used as the saddle movement restricting means, a gap 17 having a predetermined width can be formed between the saddle movement restricting portion 16B and the dash panel 12 while ensuring a predetermined rigidity. Until the rising angle of the dash panel 12 becomes equal to or greater than a predetermined size, the heel movement restricting portion 16B and the dash panel 12 can be prevented from interfering with each other. As a result, until the rising angle of the dash panel 12 becomes equal to or larger than a predetermined size, the dash panel 12 can prevent the heel movement restricting portion 16B from being pushed up in the direction of the heel 30A.
[0020]
The position of the mounting portion 16A of the metal bracket 16 is not limited to the front end in the vehicle front-rear direction of the floor panel 10, and is a position that does not interfere with the occupant foot 30 at the normal time, and the heel of the occupant foot 30 that occurs during a collision. Any position that can regulate the forward movement of 30A may be used. In this case, the timing at which the dash panel 12 and the occupant foot 30 are in contact with each other can be delayed as the mounting portion 16A is located on the rear side of the vehicle, and the bending angle θ2 of the ankle 30C is reduced along with the rising deformation of the dash panel 12. Can be prevented. Also in this case, the metal bracket 16 is set at a position where it does not contact the occupant foot 30 when the pedal is operated.
[0022]
Next, a second embodiment of the floor structure of the pedal down for a vehicle according to the present invention will be described with reference to FIGS.

Has been. A lower portion 42A of the insert 42 serves as a mounting portion 40A for the energy absorbing spacer 40, and the mounting portion 42A is fixed to the floor panel 10 by fixing means such as a pair of left and right mounting bolts 44.
[0025]
As shown in FIG. 6, the mounting bolt 44 is screwed into a nut 46 disposed on the back surface 10 </ b> B of the floor panel 10. Further, pads 44 are disposed on both the upper and lower surfaces of the upper portion 42B of the insert 42, and the upper portion 42B of the insert 42 and the pad 44 constitute a heel movement regulating portion 40B of the energy absorbing spacer 40.
[0026]

When stepped on, the toe 30B of the occupant foot 30 swings forward (in the direction of arrow B in FIG. 5 ) around the contact point P. At this time, the movement of the occupant foot 30 is caused by the energy absorbing spacer 40. There are no restrictions. For this reason, since the heel 30A of the passenger foot 30 does not float from the floor surface 25, the heel 30A can be stabilized when the accelerator pedal is operated, and a sense of incongruity is not felt.
[0029]
On the other hand, when the occupant foot 30 moves forward (in the direction of arrow A in FIG. 6 ) with respect to the floor surface 25 at the time of a collision as shown in FIG. 6 , the heel 30 </ b> A of the occupant foot 30 moves to the energy absorbing spacer 40. It contacts the heel movement restricting portion 40B via the carpet 24 and the dash silencer 50. For this reason, the forward movement of the collar 30A with respect to the floor surface 25 is regulated by the energy absorbing spacer 40.
[0030]
Further, in the present embodiment, when the dash panel 12 rises and deforms, the pad 44 of the energy absorbing spacer 40 is crushed from the state before deformation indicated by the two-dot chain line in FIG. 6 to the state indicated by the solid line. The impact received by the occupant foot 30, specifically, the bending moment acting on the ankle 30 </ b> C and the axial force pushing up in the leg axial direction can be reduced.
