  In general, side frames and hinge pillars are provided on the outer side in the vehicle width direction of the front part of the vehicle body, and the rigidity is higher than the central part in the vehicle width direction of the vehicle body. The center part in the vehicle width direction of the vehicle body is easier to deform than the part, and the amount of retreat is large. For this reason, when the vehicle crashes, the brake pedal may retreat and swing (move) outward in the vehicle width direction as the dash panel retreats. In this case, the accelerator provided on the outer side in the vehicle width direction than the brake pedal. Since the brake pedal swings on the pedal side, there is a risk of damage to the legs even when the driver depresses the accelerator pedal.

  However, in the structure of Patent Document 1, in order to cope with the swing of the brake pedal to the outside in the vehicle width direction, there is a problem that the length of the pressing member needs to be increased and the structure becomes large. .

  It is an object of the present invention to prevent the operation pedal from retreating greatly in the event of a vehicle collision and to prevent the operation pedal from swinging outward in the vehicle width direction without increasing the size of the structure in the operation pedal retreat prevention structure. It is to be.

  The structure for preventing the operation pedal from retreating is provided with an instrument panel member installed in the vehicle width direction at the rear of the pedal arm of the operation pedal, and the pedal arm is brought into contact with the instrument panel member when the pedal arm is retracted in the event of a vehicle collision. An operation pedal retraction preventing structure configured to prevent the operation pedal from retreating by being in contact with a rocking restriction member for restricting the pedal arm from rocking outward in the vehicle width direction when a vehicle collides. A swing restricting member extending from the member to the front of the vehicle body and positioned on the outer side in the vehicle width direction than the pedal arm is provided.

  In this operation pedal retreat prevention structure, an instrument panel member is installed in the vehicle width direction behind the pedal arm of the operation pedal. In this instrument panel member, a swing restricting member extending forward of the vehicle body at a position outside the pedal arm in the vehicle width direction. A brake pedal or a clutch pedal can be applied to this operation pedal.

  In the event of a vehicle collision, when the operation pedal is retracted as the dash panel is retracted, the operation pedal is received by the pedal arm of the operation pedal coming into contact with the instrument panel member. Even when the operation pedal tries to swing outward in the vehicle width direction, the swing restriction member restricts swinging of the operation pedal in the vehicle width direction outer side.

  According to a second aspect of the present invention, there is provided the structure for preventing the operation pedal from retreating, wherein the pedal arm is provided with a contact bracket extending toward the instrument panel member.

  According to a third aspect of the present invention, there is provided the structure for preventing the operation pedal from retreating. In the second aspect of the invention, the pedal arm or the abutment bracket extends inward in the vehicle width direction of the swing restricting member from the instrument panel member to the front of the vehicle body. It is characterized in that an abutting portion for abutting is provided.

  According to a fourth aspect of the present invention, in the invention of the third aspect, the swinging restricting member and the contact portion are formed of an integral L-shaped member.

  According to a fifth aspect of the present invention, in the invention, the instrument panel member is a hinge pillar that supports the side door via a bolt that is inserted and screwed into an end of the instrument panel member. It is connected to.

  According to a sixth aspect of the present invention, there is provided a structure for preventing the operation pedal from retreating, wherein the operation pedal is a brake pedal.

  According to the first aspect of the present invention, since the swing restricting member extending from the instrument panel member to the front of the vehicle body and positioned outside the pedal arm in the vehicle width direction is provided, when the operation pedal is retracted at the time of a vehicle collision, the rigidity is high and the vehicle width is increased. An instrument panel member that is long in the direction can reliably catch the operation pedal. Therefore, since the operation pedal does not move backward from the instrument panel member at the time of a vehicle collision, it is possible to prevent the driver's leg from being damaged.

  Further, since the swing restricting member restricts the pedal arm from swinging outward in the vehicle width direction, when the operation pedal is a brake pedal, the driver has to depress the accelerator pedal provided outside the brake pedal in the vehicle width direction. Even when the vehicle is depressed, it is possible to prevent the driver's leg from being damaged. In addition, since it can be realized simply by providing a swing restricting member on the instrument panel member, the structure is simple and the structure is small, and can be implemented at low cost.

  According to the second aspect of the present invention, since the pedal arm is provided with the contact bracket extending toward the instrument panel member, the load from the operation pedal is reliably transmitted to the instrument panel member when the operation pedal is retracted at the time of a vehicle collision. Can do.

  According to the invention of claim 3, since the contact portion that extends forward from the instrument panel member to the vehicle body and contacts the pedal arm or the contact bracket at the time of the vehicle collision is provided on the inner side in the vehicle width direction of the swing restricting member. By bringing the pedal arm or the contact bracket into contact with the contact portion of the swing restricting member when the operation pedal is retracted, the load from the operation pedal can be reliably transmitted to the instrument panel member.

  According to the fourth aspect of the present invention, since the swing restricting member and the contact portion are formed of an integral L-shaped member, the pedal arm swings outward in the vehicle width direction at the swing restricting member and the contact portion. It is possible to secure the required rigidity and strength when regulating the pressure.

  According to the invention of claim 5, since the instrument panel member is connected to the hinge pillar supporting the side door via the bolt inserted and screwed into the end thereof, the connection strength between the instrument panel member and the hinge pillar is remarkably high. Thus, when the operation pedal is retracted at the time of a vehicle collision, the operation pedal can be reliably received by the instrument panel member.

  According to the invention of claim 6, since the operation pedal is a brake pedal, the above effect can be obtained in the brake pedal.

  The structure for preventing the operation pedal from retreating according to the present invention is a swing restricting member that restricts the pedal arm from swinging outward in the vehicle width direction in the event of a vehicle collision, and is installed in the vehicle width direction behind the pedal arm of the operation pedal. A swing restricting member extending from the instrument panel member to the front of the vehicle body and positioned on the outer side in the vehicle width direction than the pedal arm is provided.

A substantially linear reinforcing bracket 15 extending in the vertical direction is connected to the central portion in the vertical direction on the right side of the pedal arm 11 and the connecting portion 13 of the pedal arm 11. An accelerator pedal is provided on the outer side of the brake pedal 10 in the vehicle width direction, and is connected to and supported by the dash panel 4 through a pedal support bracket 14 so as to be swingable, similarly to the brake pedal 10.

Next, a structure for preventing the operation pedal from moving backward will be described with reference to FIGS.
In the structure for preventing the operation pedal from retreating, the instrument panel upper pipe 20 is installed in the vehicle width direction behind the cowl portion 5, and is installed in the vehicle width direction below the instrument panel upper pipe 20 and behind the pedal arm 11 of the brake pedal 10. An instrument panel lower pipe 21 (which corresponds to an instrument panel member) and a steel swing restricting member 30 for restraining the pedal arm 11 from swinging outward in the vehicle width direction at the time of a vehicle collision are provided.

  Flange portions 22 are respectively provided at the left and right ends of the instrument panel lower pipe 21, and the instrument panel lower pipe 21 is joined to the hinge pillar 37 (see FIG. 8) that supports the side door via the flange portion 22. The instrument panel lower pipe 21 is configured to receive the brake pedal 10 by bringing the pedal arm 11 of the brake pedal 10 into contact with the front side portion of the instrument panel lower pipe 21 when the brake pedal 10 moves backward in the event of a vehicle collision. ing.

  A swing regulating member 30 that is U-shaped in a side view and extends forward of the vehicle body is fixed to the front portion of the instrument panel lower pipe 21. The swing restricting member 30 is provided at a position on the right side of the pedal arm 11 of the brake pedal 10 with an interval of about 10 mm. Further, both the left and right ends of the instrument panel upper pipe 20 are joined to the hinge pillar 37.

Next, the rocking restriction member 30 will be described.
As shown in FIGS. 1-5, the rocking | fluctuation control member 30 has the upper board part 30a, the front board part 30b, and the lower board part 30c, and the upper board part 30a and the lower board part 30c are front-back. Two holes 30d are formed respectively. The longitudinal length of the upper plate portion 30a is formed to be slightly larger than the longitudinal length of the lower plate portion 30c, and the rear end of the lower plate portion 30c is welded to the central portion in the vertical direction at the front portion of the instrument panel lower pipe 21. In addition to being joined, the rear end portion of the upper plate portion 30a is joined to the upper portion of the instrument panel lower pipe 21 by welding, and a closed cross-sectional shape extending in the left-right direction between the swing regulating member 30 and the instrument panel lower pipe 21 ( Box-shaped).

  The swing restricting member 30 extends from the instrument panel lower pipe 21 to the front of the vehicle body. When the brake pedal 10 tries to swing outward in the vehicle width direction at the time of a vehicle collision, the pedal arm 11 moves to the left end of the swing restricting member 30. It is comprised so that contact | abutting is possible. As described above, the swing restriction 30 has a box shape and is joined to the instrument panel lower pipe 21 by welding. Therefore, the swing restriction 30 is necessary to prevent the pedal arm 11 from swinging outward in the vehicle width direction in the event of a vehicle collision. Even when the brake pedal 10 tries to swing outward in the vehicle width direction at the time of a vehicle collision, the swing of the brake pedal 10 outward in the vehicle width direction is restricted.

Next, the operation and effect of the operation pedal retreat prevention structure will be described.
In the event of a vehicle collision, when the brake pedal 10 is retracted as the dash panel 4 is retracted, the brake arm 10 is received by the pedal arm 11 coming into contact with the instrument panel lower pipe 21 and is indicated by a two-dot chain line in FIG. Thus, the brake pedal 10 swings forward. At this time, even when the brake pedal 10 tries to swing outward in the vehicle width direction, the brake pedal 10 is received by the swing restricting member 30 and the swing of the brake pedal 10 outward in the vehicle width direction is restricted. The

  As described above, since the swing restricting member 30 extending from the instrument panel lower pipe 21 to the front of the vehicle body and positioned outside the pedal arm 11 in the vehicle width direction is provided, when the brake pedal 10 is retracted at the time of a vehicle collision, the rigidity is high and the vehicle width is increased. The brake pedal 10 can be reliably received by the instrument panel lower pipe 21 that is long in the direction. Therefore, the brake pedal 10 does not retreat backward from the instrument panel lower pipe 21 at the time of a vehicle collision, so that it is possible to prevent the driver's leg from being damaged.

  Since the swing restricting member 30 restricts the pedal arm 11 from swinging outward in the vehicle width direction, even when the driver depresses the accelerator pedal provided on the outer side in the vehicle width direction of the brake pedal 10, the driver It is possible to prevent damage to the legs. In addition, since it can be realized simply by providing the swing restricting member 30 in the instrument panel lower pipe 21, the structure is simple and the structure is small, and can be implemented at low cost.

  Further, since the swing restricting member 30 is configured in a closed cross-sectional shape extending in the left-right direction with the instrument panel lower pipe 21, the rigidity of the swing restricting member 30 is increased, and the pedal arm 11 swings outward in the vehicle width direction. It is possible to reliably regulate movement.

Next, a reverse prevention structure for an operation pedal according to the second embodiment will be described with reference to FIGS. However, the same reference numerals are given to the same components as those in the above embodiment, and only different components will be described.
In this operation pedal retreat prevention structure, the instrument panel lower pipe 21 is provided with a rocking restriction bracket 30 </ b> A having an L shape in plan view, and an abutting bracket 40 having an L shape in side view on the pedal arm 11 of the brake pedal 10. Is provided.

  The swing restriction bracket 30A is integrally formed of a contact portion 35a extending in the vehicle width direction and a swing restriction member 35b protruding forward from the right end of the contact portion 35a. The rear end of the swing restriction bracket 30A is joined to the front side portion of the instrument panel lower pipe 21 by welding so that the center portion in the vertical direction of the swing restriction bracket 30A is positioned at the center portion in the vertical direction of the instrument panel lower pipe 21. ing.

  A contact bracket 40 having a lower end extending toward the instrument panel lower pipe 21 is connected to the connecting portion 13 of the pedal arm 11 on the right side of the pedal arm 11. In the swing restricting bracket 30A, a notch 35c is formed from the rear half of the swing restricting member 35b to the right end of the contact portion 35a. The rear end of the contact bracket 40 is positioned immediately in front of the contact portion 35a of the swing restricting bracket 30A. When the brake pedal 10 is retracted at the time of a vehicle collision, the contact bracket 40 becomes the contact portion 35a. It is comprised so that it may contact | abut.

  The contact bracket 40 is provided with a space of about 10 mm between the right side surface of the contact bracket 40 and the swing restricting member 35b of the swing restricting bracket 30A, and the brake pedal 10 is placed outward in the vehicle width direction when the vehicle collides. When swinging is attempted, the contact bracket 40 is configured to contact the swing restriction member 35b, and therefore, the swing of the brake pedal 10 to the outside in the vehicle width direction is reliably restricted.

Next, a connection structure between the instrument panel lower pipe 21 and the hinge pillar 37 will be described.
As shown in FIG. 8, in the state where the nut member 38 is inserted into the female screw portion 21 a formed at the left and right end portions of the instrument panel lower pipe 21 and screwed together, the hinge pillar 37, the nut member 38, and the instrument panel lower pipe 21 are connected. On the other hand, by inserting the bolt 39 and screwing the bolt 39 into the nut member 38, the instrument panel lower pipe 21 is assembled in a compressed state in the length direction, and the instrument panel lower pipe 21 is connected to the hinge pillar 37, respectively. Has been.

  Thus, since the contact bracket 40 extending toward the instrument panel lower pipe 21 is provided on the pedal arm 11 of the brake pedal 10, when the brake pedal 10 retreats at the time of a vehicle collision, the load from the brake pedal 10 is reduced to the instrument panel lower pipe. 21 can be reliably transmitted. Since a contact portion 35a extending from the instrument panel lower pipe 21 to the front of the vehicle body and contacting the contact bracket 40 at the time of a vehicle collision is provided on the inner side in the vehicle width direction of the swing restriction bracket 30A, the brake pedal 10 is retracted at the time of the vehicle collision. Sometimes, the load from the brake pedal 10 can be reliably transmitted to the instrument panel lower pipe 21 by bringing the contact bracket 40 into contact with the contact portion 35a.

  Furthermore, since the swing restricting bracket 30A is integrally formed with the contact portion 35a and the swing restricting member 35b in an L shape in plan view, it is necessary for restricting the swing of the pedal arm 11 to the outside in the vehicle width direction. High rigidity can be secured. Since the instrument panel lower pipe 21 is connected to the hinge pillar 37 that supports the side door via the bolt 39 and the nut member 38 inserted and screwed into the end portion thereof, the connection strength between the instrument panel lower pipe 21 and the hinge pillar 37 is determined. When the brake pedal 10 moves backward during a vehicle collision, the brake pedal 10 can be reliably received by the instrument panel lower pipe 21.

  In this case, coupled with the fact that the connection strength between the instrument panel lower pipe 21 and the hinge pillar 37 is remarkably increased, and that the vehicle width direction center portion of the vehicle body is more easily deformed than the vehicle width direction outer side portion of the vehicle body, and the retraction amount is large. Thus, the brake pedal 10 is likely to swing outward in the vehicle width direction when the backward movement of the brake pedal 10 is restricted by the instrument panel lower pipe 21, but the swinging of the brake pedal 10 can be reliably restricted by the swing restricting member 35b. It is.

Next, a modified example in which the above embodiment is partially modified will be described.
1] In the first embodiment, as in the second embodiment, the nut member 38 and the bolt 39 may be connected to connect the instrument panel lower pipe 21 and the hinge pillar 37.
2] In the second embodiment, the nut member 38 and the bolt 39 may be omitted with respect to the connection between the instrument panel lower pipe 21 and the hinge pillar 37, and the instrument panel lower pipe 21 and the hinge pillar 37 may be connected as in the first embodiment. Further, the hinge pillar 37 and the instrument panel lower pipe 21 may be assembled not in a compressed state but in a tensile state.

3] In the second embodiment, the abutment bracket 40 may be omitted, and the pedal arm 11 itself may be positioned on the inner side in the vehicle width direction of the swing restricting portion 35b.
4] The operation pedal can be applied to a clutch pedal provided inside the brake pedal 10 in the vehicle width direction in addition to the brake pedal 10.
5] In addition, those skilled in the art can implement the present invention in various forms added with various modifications without departing from the spirit of the present invention, and the present invention includes such modifications. .
