Description

  The present invention relates to a footrest structure for a vehicle attached to a vehicle body.

  There is a vehicle type in which a footrest is provided at the foot of the driver's seat of the vehicle. The footrest is a member for placing the driver's foot (for example, the left foot), which is not used much during driving, in an easy state while the driver is seated on the seat.

  Some footrests are attached to a lower part of a dash panel, a floor panel or the like of a vehicle body. In addition, the footrest is provided with a placement portion on which a driver's foot is placed, and the placement portion is inclined at a predetermined angle with respect to the upper surface of the floor panel of the vehicle body.

  For example, when the dash panel is deformed at the time of a vehicle collision, it is necessary to ensure the safety of the driver and the passenger in the passenger seat. In particular, it is important to prevent contact between the dash panel and the passenger. For example, as disclosed in Patent Document 1, a technique is known in which a convex shape is provided in front of the toe so that the foot does not contact the panel so that the foot does not contact the panel at the time of collision.

JP 2014-061783 A

  However, as in the above example, in order to provide a convex shape (convex step) for stopping the movement of the foot in front of the toes, it is necessary to increase the component shape in the vehicle front direction. This has a problem that it leads to an increase in component weight and component cost. In addition to setting a convex shape in front of the toes, a method of providing a large concave step in the buttock is also conceivable, but in this case, comfort during normal use may be deteriorated.

  The present invention has been made to solve the above problems, and its purpose is to regulate the movement of the occupant's feet during a vehicle collision without deteriorating comfort during normal use and increasing the size of the parts. It is to provide a footless structure that can ensure the safety of passengers.

  In order to achieve the above object, the footrest structure for a vehicle according to the present invention is attached to a dash panel or a floor panel at the front of the vehicle and covered with a floor carpet. In the footrest structure, a concave step portion penetrating in the vehicle width direction is provided at an intermediate portion of the footrest on the vehicle lower surface in the vehicle front-rear direction, and the footrest is attached to the dash panel or the floor panel. In this state, a reference surface that is an upper stage of the step portion is formed with respect to the lower surface of the vehicle, and a thin portion that is recessed upward of the vehicle is provided on the reference surface.

  Moreover, in the one aspect | mode of the footrest structure for vehicles which concerns on this invention, the attaching part for attaching the said footrest to the said dash panel or the said floor panel is provided in the vehicle front side rather than the said thin part.

  In one aspect of the footrest structure for a vehicle according to the present invention, a lower groove extending from the end in the vehicle width direction of the footrest toward the thin portion is formed on the reference surfaces on both sides in the vehicle width direction of the thin portion. ing.

  Moreover, in one aspect of the footrest structure for a vehicle according to the present invention, an upper groove extending so as to connect both ends of the footrest in the vehicle width direction is formed on the upper surface of the vehicle at a position corresponding to the vehicle longitudinal direction position of the lower groove. Has been.

  Further, in one aspect of the footrest structure for a vehicle according to the present invention, the footrest is formed of a foam material, and a firing magnification at a vehicle front portion rather than the step portion, and a firing magnification at a vehicle rear portion than the step portion. Are different from each other.

  Moreover, in one aspect of the footrest structure for a vehicle according to the present invention, the footrest is formed of a foam material, and the vehicle at the reference position when the vehicle longitudinal direction position of the upper groove and the lower groove is a reference position. The front portion and the rear portion of the vehicle are formed to have different firing magnifications.

  According to the present invention, by providing the stepped portion, the intermediate portion of the footrest fixed to the vehicle on the lower surface of the vehicle floats from the dash panel surface (or the surface of the floor panel), and the lower surface of the footrest A space (gap) can be created between the front panel and the surface of the dash panel, etc., and when the footrest breaks back and forth in the front and rear of the vehicle with a thin wall portion, A step can be generated in the fracture portion. As a result, the shoe heel can be caught on this step, and the foot can be prevented from moving forward.

  In addition, according to one aspect of the present invention, since the attachment portion is provided on the front side of the stepped portion, when the above-described breakage occurs, the front-side broken piece can be held in a posture without rotating. On the other hand, since the rear broken piece has no mounting portion, the rear broken piece rotates forward from the stepped portion, and the front end of the rear broken piece is lowered with respect to the front broken piece. In the rear fracture fragment, a step can be generated in which the front fracture fragment is surely higher than the rear fracture fragment. In addition, when the heel is caught, it is possible to reliably prevent the foot from moving due to the front breakage piece, so that the effect of restricting the movement of the foot forward of the vehicle can be enhanced.

  Further, according to one embodiment of the present invention, by providing the lower groove, the thin portion can be broken at the lower groove as a boundary, and thus can be broken at a target location.

  Moreover, according to one aspect of the present invention, by providing the upper groove together with the lower groove, a straight fracture surface can be formed in the vehicle up-down direction of the footrest.

  Moreover, according to one aspect of the present invention, by setting the firing magnification as described above, for example, the density of the material of the rear fracture portion can be reduced, and the rear side can be easily deformed. Thereby, generation | occurrence | production of a fracture | rupture can be produced reliably. Further, by changing the expansion ratio between before and after the stepped portion, breakage at boundary lines with different hardness is likely to occur. In addition, since the shoe heels can easily sink, the heels can easily stop behind the footrest, and when a step occurs, the heel is surely positioned behind the step so that the foot can slide forward. When this is done, the hook can be easily caught on the step.

  In addition, according to one aspect of the present invention, a synergistic effect is brought about by the effect of different firing magnifications and the brittle effect of the groove, and the position of the break can be controlled.

It is a disassembled perspective view of the vehicle front part provided with the footrest structure for vehicles concerning the present invention. FIG. 2 is a side sectional view of the footrest structure of FIG. 1, and is a longitudinal sectional view at the center of the footrest in the vehicle width direction. It is a perspective view when the footrest of FIG. 1 is seen from the vehicle lower side. It is a sectional side view which shows the state which the dash panel of FIG. 2 deform | transformed and the footrest fractured | ruptured.

  Hereinafter, an embodiment of a footrest structure for a vehicle according to the present invention will be described with reference to the drawings (FIGS. 1 to 4).

  In the vehicle footrest structure of the present embodiment, a footrest 30 is attached to a dash panel 10 as shown in FIG. The footrest 30 is covered with a rising portion 21 of a floor carpet 20 disposed on a floor panel (not shown). In FIG. 1, detailed structures of the dash panel 10, the footrest 30, and the floor carpet 20 are omitted.

  The dash panel 10 is a metal panel member that separates the vehicle compartment from the engine compartment. Although detailed explanation is omitted, instruments such as instruments are attached to the upper part of the dash panel 10 on the vehicle, and cables and the like of instruments operated by the driver pass therethrough.

  As shown in FIG. 2, the dash panel 10 includes a main surface portion 11 that extends in the vehicle vertical direction, a curved portion 12, and a bottom surface portion 13. The vehicle front side of the main surface portion 11 is an engine room. Various devices are attached to the upper portion of the main surface portion 11 as described above.

  The curved portion 12 is a portion that is disposed on the lower surface of the main surface portion 11 and is formed integrally with the main surface portion 11. The curved portion 12 is curved from the vehicle vertical direction to the vehicle front-rear direction as it goes rearward of the vehicle. The bottom surface portion 13 is a portion extending from the vehicle rear end of the curved portion 12 to the vehicle rear side, and is connected to a floor panel (not shown).

  The footrest 30 is attached from the vehicle front portion of the bottom surface portion 13 to the vehicle front portion of the bending portion 12. The curved portion 12 is provided with a protruding portion 15 for attaching the footrest 30. The projecting portion 15 projects upward from the upper surface of the curved portion 12. In this example, as shown in FIG. 2, it protrudes obliquely upward slightly to the rear of the vehicle.

  A clip insertion hole 15 a into which the clip 41 can be inserted is formed in the vehicle upper portion of the protruding portion 15. Further, a bolt insertion hole 15 b into which a stud bolt (welding bolt) 42 can be inserted is formed in the vehicle lower portion of the protruding portion 15. A wall 15c is provided between the clip insertion hole 15a and the bolt insertion hole 15b, and a through hole 15d is formed in the wall 15c so as to penetrate in the vehicle vertical direction. The stud bolt 42 inserted into the bolt insertion hole 15b is inserted into the through hole 15d.

  Next, the shape of the footrest 30 will be described. The footrest 30 is a member made of a foam material such as urethane or foamed polystyrene and extending in the vehicle front-rear direction.

  A mounting surface 31 for mounting the driver's feet is formed on the vehicle upper portion of the footrest 30. The mounting surface 31 is inclined so as to go upward in the vehicle as it goes forward of the vehicle in a state where the footrest 30 is attached to the dash panel 10. An installation surface 32 that is installed on the bending portion 12 and the bottom surface portion 13 is formed at the vehicle lower portion of the footrest 30. The installation surface 32 corresponds to the surface shapes of the curved portion 12 and the bottom surface portion 13 on which the footrest 30 is installed. On both sides of the footrest 30 in the vehicle width direction, outer surfaces parallel to each other are formed. Each outer surface is a surface that rises above the vehicle with respect to the curved portion 12 and the bottom surface portion 13.

  The shape of the lower part of the vehicle of the footrest 30 will be described. A concave stepped portion 33 is provided at an intermediate portion of the installation surface 32 in the vehicle front-rear direction so as to be recessed above the vehicle from the installation surface 32. The step portion 33 penetrates in the vehicle width direction, and a flat reference surface 33 a is formed on the bottom of the concave step portion 33. The reference surface 33a is formed above the installation surface 32 and extends in the vehicle width direction so as to connect the outer surfaces on both sides of the footrest 30 in the vehicle width direction. In a state where the footrest 30 is attached to the dash panel 10, the installation surface 32 is at the lower level, and the reference surface 33a is at the upper level.

  In the center of the reference surface 33a, a thin portion (meat stealing portion) 34 that is recessed toward the inside of the footrest 10 toward the vehicle upper side is provided. The thin portion 34 is formed with a substantially square hole as viewed from the bottom of the vehicle. The thickness of the thin portion 34 in the vehicle vertical direction is thinner than the thickness in the vehicle vertical direction of the vehicle front portion and the vehicle rear portion of the step portion 33. Here, the thickness of the thin portion 34 in the vertical direction of the vehicle is a thickness formed between the bottom surface 34a of the thin portion 34 formed above the reference surface 33a and the mounting surface 31. .

  Similarly, the thickness of the thin portion 34 in the vehicle width direction is thinner than the thickness in the vehicle width direction of the front portion and the rear portion of the step portion 33. Here, the thickness in the vehicle width direction of the thin portion 34 is the thickness formed between the side wall surface in the vehicle width direction of the hole forming the thin portion 34 and the outer surface of the footrest 30. The strength of the periphery of the thin portion 34 provided at the middle portion in the vehicle longitudinal direction is lower than the strength of the front and rear portions of the vehicle, and the thin portion 34 is more easily deformed than other portions.

  An attachment portion 37 for attaching the footrest 30 to the protruding portion 15 of the dash panel 10 is provided on the installation surface 32 of the thin portion 34 on the vehicle front side. The mounting portion 37 is formed with a quadrangular recess that is recessed upward in the vehicle as viewed in the vehicle vertical direction, and a through hole 37b that penetrates in the vehicle vertical direction is formed on the bottom surface 37a of the recess. The protrusion 15 of the dash panel 10 can be inserted into the through hole 37b.

  The clip 41 is inserted from the mounting portion 37 of the footrest 30 into the clip insertion hole 15 a of the protruding portion 15 in a state where the protruding portion 15 is inserted into the through hole 37 b of the mounting portion 37. On the other hand, the stud bolt 42 is penetrated from the vehicle lower side (back side) of the footrest 30 into the through hole 15d provided in the protruding portion 15, and the clip 41 inserted from above is fitted to the stud bolt 42. At this time, the head of the clip 41 is hooked on the bottom surface 37 a of the recess, and the footrest 30 is attached to the dash panel 10.

  Here, a state where the dash panel 10 is deformed and the footrest 30 is broken when the vehicle collides will be described. When receiving an impact from the front of the vehicle, a force F as shown in FIG. 4 acts on the dash panel 10. Due to the impact, the dash panel 10 is deformed rearward of the vehicle. Thereby, a force F from the front of the vehicle acts on the footrest 30. By this force F, it breaks at the thin-walled portion 34 of the stepped portion 33 that is easily deformed, and is divided into two broken pieces before and after the vehicle.

  By providing the stepped portion 33 as described above, the intermediate portion in the vehicle front-rear direction of the installation surface 32 of the footrest 30 in a state of being fixed to the dash panel 10 floats from the floor panel surface (not shown). Thus, a space (gap) can be generated between the installation surface 32 of the footrest 30 and the vehicle interior side surface of the dash panel 10. When the thin portion 34 breaks due to the above-described collision or the like, the rear broken piece 30b of the broken footrest 30 moves downward in the vehicle. That is, as shown in FIG. 4, the front end of the rear broken piece 30b moves below the step portion 33 of the front broken piece 30a. As a result, the step 22 can be generated before and after the broken portion 39 in the vehicle. It becomes possible to prevent the foot 43a of the shoe 43 from being caught on the step 22 and moving the foot forward.

  Since the attachment portion 37 is provided as described above, the posture can be maintained without the footrest 30 rotating. On the other hand, the rear portion of the vehicle rather than the step portion 33 does not have the attachment portion 37, and therefore can rotate forward from the step portion 33. As described above, the vehicle front end of the rear broken piece 30b when it breaks at the boundary of the stepped portion 33 is lowered below the vehicle with respect to the front broken piece 30a, and the front broken piece 30a and the rear broken piece 30b The step 22 can be generated such that the fragment 30a is reliably raised. Further, when the driver's heel 43a is caught, it is possible to reliably prevent the foot from moving by the front side breaking piece 30a, and it is possible to enhance the effect of restricting the movement of the foot to the front side of the vehicle.

  As shown in FIGS. 2 and 3, the footrest 30 of the present embodiment is provided with grooves 35 and 36. Hereinafter, the grooves 35 and 36 will be described. A lower groove 35 extending in the vehicle width direction from the outer wall of the footrest 30 to the inner wall of the thin portion 34 is formed in each of the reference surfaces 33a on both sides of the thin portion 34 in the vehicle width direction. The front and rear direction positions of the lower grooves 35 formed on the walls on both sides are formed to be the same position. On the other hand, an upper groove 36 is formed on the mounting surface 31 at a position corresponding to the position in the vehicle longitudinal direction of each lower groove 35. The upper groove 36 extends in the vehicle width direction so as to connect the outer surfaces of both sides of the footrest 30 in the vehicle width direction.

  The portion where the lower groove 35 is formed is a portion whose strength is lower than that of the thin portion 34 around the lower groove 35. Therefore, when the collision occurs, it is easy to break with the lower groove 35 as a boundary. That is, it is possible to break at the target portion.

  By forming the upper groove 36, the portion where the upper groove 36 and the lower groove 35 are formed becomes a portion whose strength is lower than that of the thin portion 34 around the grooves 35 and 36. Therefore, when the collision occurs, it is easy to break with the upper groove 36 as a boundary. Here, by aligning the vehicle longitudinal direction positions of the upper groove 36 and the lower groove 35, it is possible to form a straight fracture surface that connects the upper groove 36 and the lower groove 35 at the fracture portion 39. By forming such a fracture surface, the heel 43a is more easily caught and the effect of preventing the foot from moving forward is improved. At this time, it is desirable to set a groove width and a groove depth so that both the upper groove 36 and the lower groove 35 are the starting points of the fracture.

  Moreover, you may comprise so that the foaming magnification of a foam material may differ partially as a modification of the said structure. For example, the firing magnification at the front portion of the vehicle relative to the step portion 33 may be different from the firing magnification at the rear portion of the vehicle relative to the step portion 33. In this case, the firing magnification at the rear portion of the stepped portion 33 in the vehicle may be set to be higher than the firing magnification at the front portion of the stepped portion 33 in the vehicle.

  By setting the firing magnification as described above, the density of the material on the vehicle rear side of the step portion 33 is lowered, and the footrest 30 on the rear side of the step portion 33 is easily deformed. Thereby, generation | occurrence | production of a fracture | rupture can be produced reliably. Further, by changing the expansion ratio between before and after the step portion 33, breakage at boundary lines with different hardness is likely to occur. Further, since the heel 43a of the shoe 43 is likely to sink, the heel 43a is likely to stop behind the footrest 30, and when the step 22 is generated due to a collision, the heel 43a is surely positioned behind the step 22 in the vehicle. In addition, the heel 43a can be easily caught on the step 22 when the foot is about to slide forward.

  Further, the position that becomes the boundary of the expansion ratio may be the vehicle longitudinal direction position of the upper groove 36 and the lower groove 35. In other words, the firing magnification may be different before and after the surface including the upper groove 36 and the lower groove 35 extending in the vehicle vertical direction. A synergistic effect can be obtained by the fragility due to the upper groove 36 and the lower groove 35 and the effect of promoting the destruction caused by different firing magnifications. Moreover, it becomes easier to control the position of the break.

  The description of the above embodiment is an example for explaining the present invention, and does not limit the invention described in the claims. Moreover, each part structure of this invention is not restricted to the said embodiment, A various deformation | transformation is possible within the technical scope as described in a claim.

  For example, in this embodiment, although the footrest 30 is attached to the dash panel 10, it is not restricted to this. The vehicle may be attached across the floor panel and the dash panel at a position where the vehicle front end of the floor panel and the vehicle lower end of the dash panel are connected. In addition, when the floor panel has a shape that rises at the front of the vehicle, a footrest may be attached to the rising portion of the floor panel. In the above example, the lower groove 35 and the upper groove 36 are provided, but the present invention is not limited to this. In the modification, the firing magnification is set so that the rear part is higher than the front part of the vehicle, but it is also possible to set the front part to be higher.
