  However, when an organ-type pedal device is employed, for example, when the vehicle collides forward during the stepping operation of the pedal device, the foot of the occupant who has slid on the tread surface and moved forward is the front end (upper end) of the pedal device. There is a concern that the toes may interfere with a dash panel as a vehicle body panel located in front of the pedal device in the vehicle.

  By the way, in the said patent document 1, what hold | maintained the airbag apparatus between the 1st, 2nd plate members which comprise a pedal apparatus is disclosed, and when a vehicle collides ahead, the airbag mentioned above is developed. By doing so, the impact force input to the soles of the occupants who stepped on the pedal device can be absorbed and relaxed.

  However, in the prior art disclosed in Patent Document 1, the impact force input from the pedal device at the time of a forward collision of the vehicle is absorbed and alleviated, and the occupant's foot climbs over the front end of the pedal device and dashes. It does not prevent interference with the panel.

  An object of the present invention is to provide a vehicle compartment front structure that can prevent a passenger's foot from getting over the front end of a pedal device and interfering with a dash panel during a frontal collision of the vehicle.

  The vehicle compartment front structure of the vehicle according to the present invention includes a floor panel that forms a bottom surface of the vehicle interior, a dash panel that rises upward from the floor panel, a driver seat disposed on the floor panel, and the dash panel. And a pedal device disposed on the rear side of the vehicle, wherein the pedal device is supported by the floor panel so as to be pivotable in the vehicle front-rear direction in front of the driver's seat. An instrument panel is disposed in front of the driver's seat in the vehicle width direction, and at the front end of the pedal device, at least the pedal device is at a maximum depressed position, and the driver's seat When the occupant's feet seated on the vehicle move to the front of the vehicle, the occupant's feet are provided with a guide portion that guides the lower part of the instrument panel.

  According to this configuration, when at least the pedal device is at the maximum depression position and the foot of the passenger in the driver's seat moves forward of the vehicle due to a frontal collision of the vehicle, the foot is guided to the lower part of the instrument panel by the guide portion. With this configuration, it is possible to prevent the occupant's toes from getting over the front end of the pedal device and interfering with the dash panel.

  According to this configuration, it is possible to prevent an occupant's feet from inadvertently coming into contact with the guide portion during normal driving before the vehicle collides forward. In this case, the occupant does not feel the shape of the guide portion with his / her foot during normal driving, and thus can depress the pedal device without feeling uncomfortable.

  In one embodiment of the present invention, the instrument panel includes a drooping portion that hangs downward at a lower front end of the instrument panel, and the drooping portion is disposed so as to extend toward the guide portion.

  According to this configuration, the distance from the guide portion to the lower portion of the instrument panel can be set short, in other words, the moving distance until the foot of the occupant moving forward of the vehicle contacts the lower portion of the instrument panel. Can be shortened. In this case, it is possible to reduce the burden on the foot when it comes into contact with the lower part of the instrument panel, and it is possible to improve safety.

  Specifically, since the foot can be brought into contact with the lower part of the instrument panel at an early stage before the forward movement of the vehicle is accelerated, the impact applied to the foot tip can be reduced.

  Further, by shortening the distance, the passenger's feet can be restrained in as short a time as possible. For this reason, it is possible to restrain the foot at an early stage before the bending angle of the foot greatly changes, and it is possible to reduce the burden on the foot when contacting the lower portion of the instrument panel.

  In one embodiment of the present invention, an impact absorbing member that absorbs an input load from below is disposed at the lower portion of the instrument panel.

  According to this configuration, the impact when the occupant's foot comes into contact with the lower portion of the instrument panel can be reliably absorbed by the impact absorbing member, and safety can be improved.

  In one embodiment of the present invention, the impact absorbing member is disposed in a range corresponding to a rotation range of the pedal device.

  According to this structure, the said impact can be absorbed reliably irrespective of the rotation angle of a pedal apparatus.

  In one embodiment of the present invention, the front end of the guide portion is supported by the lower portion of the instrument panel so as to be slidable in the vehicle front-rear direction.

  According to this configuration, the gap between the pedal device and the instrument panel can be completely closed by the guide portion. For this reason, it can prevent more reliably that a passenger | crew's toe gets over the front end of a pedal apparatus and interferes with a dash panel.

  In one embodiment of the present invention, the front end of the guide portion is set wider than the rear end.

  According to this configuration, for example, even when the occupant's feet are displaced in the vehicle width direction and moved diagonally forward due to a frontal collision of the vehicle, the feet are reliably secured by the front end of the wide guide portion. Can be guided to the bottom of the instrument panel.

  According to the present invention, when at least the pedal device is at the maximum depression position and the foot of the driver's occupant moves forward of the vehicle due to a frontal collision of the vehicle, the foot is guided to the lower part of the instrument panel by the guide portion. With this configuration, it is possible to prevent the occupant's toes from getting over the front end of the pedal device and interfering with the dash panel.

  The accelerator pedal 8 and the brake pedal 9 are disposed behind the dash panel 4 in the vehicle and are positioned in front of the driver's seat 5 so that the occupant X can perform a stepping operation. As shown in FIG. 3, the accelerator pedal 8 is supported by the floor panel 2 so as to be pivotable in the vehicle front-rear direction, while the brake pedal 9 is attached to the cross car beam 10 as shown in FIG. The pedal bracket 11 is supported so as to be pivotable in the vehicle front-rear direction in a suspended state.

  Here, as shown in FIGS. 2 and 4, the cross car beam 10 is a cylindrical member extending in the vehicle width direction inside the instrument panel 6, and the instrument panel 6 is connected to the cross car beam 10. It is supported. The member 12 shown in FIGS. 2 and 4 is a knee protector attached to the cross car beam 10 in accordance with the position of the knee of the occupant X seated in the driver's seat 5.

  Next, the structure of the accelerator pedal 8 will be described in detail. As shown in FIGS. 1 to 4, the accelerator pedal 8 is supported by the base member 81 fixed to the front end of the floor panel 2, and the rear end hinge portion according to the stepping operation of the occupant. This is a so-called organ-type pedal device that includes a tread plate 82 that rotates about a fulcrum 82a.

  The tread plate 82 is made of a synthetic resin plate-like molded body or the like, and has a thin-walled rear end hinge portion 82a at a lower end portion thereof, and a locking portion 82b locked on the upper surface of the rear portion of the base member 81 (see FIG. 3). In addition, the intermediate portion has a tread surface portion 82c for the occupant X to abut on his / her foot Xa to perform a predetermined stepping operation.

  Further, a guide portion 82d that curves toward the lower portion of the instrument panel 6 is provided further forward of the tread surface portion 82c, and on both sides in the vehicle width direction at the front end of the guide portion 82d, FIG. As shown in FIG. 4, pins 83, 83 projecting outward in the vehicle width direction are attached.

  As shown in FIG. 3, the tread plate 82 can be rotated in the vehicle front-rear direction with the rear end hinge portion 82a as a fulcrum in a state in which the locking portion 82b located at the lower end thereof is locked to the base member 81. Has been.

  In the present embodiment, the fulcrum is formed by the thin rear end hinge portion 82a, but the present invention is not necessarily limited thereto. For example, a rod-shaped hinge shaft may be disposed at a position corresponding to the rear end hinge portion 82a, and the base portion 81 and the tread plate 82 may be connected via the hinge shaft.

  On the other hand, as shown in FIGS. 2 and 3, the base member 81 is formed with first and second mounting portions 81a and 81b that are recessed toward the lower floor panel 2, and at the rear end portion thereof, as shown in FIG. As shown, an engaging portion 81c having an engaging groove with which the engaging portion 82b of the tread plate 82 is engaged is formed. In the first mounting portion 81a, an insertion hole for the bolt 13 is formed in the bottom portion, and in the second mounting portion 81b, a clip locking portion 81d protrudes toward the lower floor panel 2 on the bottom surface of the bottom portion. It is installed.

  Further, as shown in FIG. 3, hat-shaped first and second attached portions 14 and 15 to which the first and second attachment portions 81a and 81b are fixed are disposed at the front end of the floor panel 2. At the same time, the floor mat 3 is provided with an installation hole for installing it at a predetermined position corresponding to the position of the base portion 81.

  Then, the bolt 13 of the first attachment portion 81a is screwed to the weld nut 16 fixed in advance to the lower surface of the upper wall of the first attachment portion 14, and the locking hole formed in the second attachment portion 15 is inserted. The base member 81 is attached to the floor panel 2 by inserting the clip engaging portion 81d of the second attachment portion 81b. Thus, the accelerator pedal 8 (tread plate 82) is supported by the flow panel 2 so as to be rotatable in the vehicle front-rear direction in front of the driver's seat 5 in the vehicle.

  By the way, the instrument panel 6 is composed of a synthetic resin plate-like molded body that is softer than the dash panel 4, such as the panel main body 61 and the under cover 62 shown in FIGS. 2 and 4.

  Among these, the under cover 62 is a member that covers the internal space of the instrument panel 6 from below, and has a drooping portion 62 a that hangs downward toward the accelerator pedal 8 at its front end. A pair of left and right recessed grooves 62b and 62b recessed in the vehicle width direction are formed on the lower surface portion of the hanging portion 62a, and a pin 83 attached to the guide portion 82d of the accelerator pedal 8 is formed in the recessed groove 62b. It is mated. Thereby, in this embodiment, the guide part 82d is supported by the lower part of the instrument panel 6. FIG.

  Further, as shown in FIG. 4, the concave groove 62 b of the under cover 62 is formed in a substantially arc shape along the movement locus of the pin 83 when the tread plate 82 (accelerator pedal 8) is depressed. Therefore, when the occupant X performs a stepping operation, the pin 83 slides in the vehicle longitudinal direction along the concave groove 62b, and the tread plate 82 is indicated by a solid line in FIG. 4 with the rear end hinge portion 82a as a fulcrum. It rotates from the non-operation position to the maximum depression position indicated by a two-dot chain line.

  Further, as shown in FIGS. 2 and 4, an impact absorbing member 17 made of urethane, synthetic rubber, or the like is disposed in the internal space of the instrument panel 6 corresponding to the rotation range of the tread plate 82. Yes. The shock absorbing member 17 is positioned between the under cover 62 and the stopper bracket 18 disposed above the shock absorbing member 17, and has a mounting seat 62c having a convex cross section formed on the under cover 62. By connecting the stopper bracket 18 with a bolt 19 and a nut 20, the shock absorbing member 17 is fixed at a predetermined position.

  Next, a case where the vehicle collides forward during the depression operation of the accelerator pedal 8 will be described with reference to FIG. In this case, the tread plate 82 of the accelerator pedal 8 is inclined to the front of the vehicle by the depressing operation. In particular, when the tread plate 82 is depressed to the maximum depressed position as shown in FIG. The orientation is closer to the horizontal direction. For this reason, as the tread plate 82 is stepped on more greatly, the foot Xa of the occupant X becomes easier to move toward the dash panel 4 in front of the vehicle.

  Therefore, in the present embodiment, when the tread plate 82 is at the maximum depressed position, the guide portion 82d moves the foot Xa forward and upward as indicated by the arrow α, and finally the foot tip is indicated by a two-dot chain line in the figure. As shown in FIG. 6, the instrument panel 6 is guided to a hanging part 62a at the lower part.

  Thus, in the present embodiment, when at least the tread plate 82 (accelerator pedal 8) is at the maximum depressed position shown in FIG. 5 and when the foot Xa of the occupant X moves forward of the vehicle due to a frontal collision of the vehicle, Since Xa is guided to the lower portion of the instrument panel 6 by the guide portion 82d, it is possible to prevent the foot of the occupant X from getting over the front end of the tread plate 82 and interfering with the dash panel 4.

  Further, by arranging the guide portion 82d in front of the tread portion 82c in the vehicle, it is possible to prevent the foot Xa from inadvertently coming into contact with the guide portion 82d during normal driving before the vehicle collides forward. In this case, since the occupant X does not feel the curved shape of the guide portion 82d with the foot Xa during normal driving, the occupant X can step on the tread plate 82 without feeling uncomfortable.

  In addition, since the hanging portion 62a extending toward the guide portion 82d is disposed at the lower front end of the instrument panel 6, the distance from the guide portion 82d to the lower portion of the instrument panel 6 can be set short. If it does so, the movement distance until the leg | foot Xa which moves ahead of a vehicle contact | abuts the lower part of the instrument panel 6 can be shortened. In this case, the burden on the foot Xa when it comes into contact with the instrument panel 6 can be reduced, and the safety can be improved.

  Specifically, since the foot Xa can be brought into contact with the lower portion of the instrument panel 6 at an early stage before the forward movement of the vehicle is accelerated, the impact applied to the foot tip can be reduced.

  Furthermore, by shortening the distance, the foot Xa can be restrained in as short a time as possible. For this reason, the foot Xa can be restrained at an early stage before the bending angle of the foot Xa largely changes, and the burden on the foot Xa when contacting the lower portion of the instrument panel 6 can be reduced.

  In addition, since the impact absorbing member 17 is disposed in the lower part of the instrument panel 6, a load from below can be absorbed by the impact absorbing member 17. For this reason, the impact when the foot Xa comes into contact with the lower portion of the instrument panel 6 can be reliably absorbed by the impact absorbing member 17, and the safety can be improved.

  Further, by disposing the shock absorbing member 17 in a range corresponding to the rotation range of the tread plate 82, the shock can be reliably absorbed regardless of the rotation angle of the tread plate 82.

  Further, the front end of the guide portion 82d is supported by a concave groove 62b formed in the lower portion of the instrument panel 6 so as to be slidable in the vehicle front-rear direction, so that the gap between the tread plate 82 and the instrument panel 6 is reduced. It can be completely blocked by 82d. For this reason, it can prevent more reliably that the foot tip of passenger | crew X gets over the front end of the tread board 82, and interferes with the dash panel 4. FIG.

  FIG. 6 shows another embodiment of the vehicle compartment front structure according to the present invention. In the embodiment shown in FIG. 6, in the tread plate 82 of the accelerator pedal 8, the front end of the guide portion 182 d is set wider than the rear end. In FIG. 6, the same components as those in the previous embodiment shown in FIGS.

  In the case of the present embodiment shown in FIG. 6, for example, even when the foot Xa (see FIG. 1 or the like) of the occupant X shifts in the vehicle width direction and moves diagonally forward due to a frontal collision of the vehicle, the width is increased. The foot Xa can be reliably guided to the lower part of the instrument panel 6 by the set front end of the guide portion 182d.

  By the way, in this embodiment, as in the first embodiment shown in FIGS. 1 to 5, pins 83, 83 are attached to both sides in the vehicle width direction at the front end of the guide portion 182 d. However, it fits into the concave grooves 162b and 162b formed in the lower part of the instrument panel 6 (the hanging part 62a). In the instrument panel 6, the concave grooves 162 b and 162 b are spaced apart from the concave grooves 62 b and 62 b (see FIG. 2 and the like) of the first embodiment, corresponding to the front end of the guide portion 182 d set to be wide. Is formed.

  Further, as shown in FIG. 6, when other pedals such as a brake pedal 9 are disposed on the side of the accelerator pedal 8, both pedals 8, 9 are prevented from the viewpoint of preventing the pedals 8, 9 from being mistakenly pressed. It is preferable to form a predetermined interval between them. Therefore, in the present embodiment, only the front end of the guide portion 182d positioned above the tread portion of the brake pedal 9 is set to be wide, and the tread portion 82c that is substantially at the same height as the tread portion of the brake pedal 9 is The same width as the first embodiment shown in FIGS. 1 to 5 is set.

  Other functions and effects are the same as those of the previous embodiment.

  7 and 8 show still another embodiment of the vehicle compartment front structure according to the present invention. In the embodiment shown in FIGS. 7 and 8, the front end of the guide portion 282 d is not supported by the lower portion of the instrument panel 6 in the tread plate 82 of the accelerator pedal 8. 7 and 8, the same components as those in the previous embodiment shown in FIGS. 1 to 5 are denoted by the same reference numerals and description thereof is omitted.

  In the present embodiment, when at least the tread plate 82 (accelerator pedal 8) is at the maximum depressed position shown in FIG. 8 and the foot Xa moves forward of the vehicle due to a forward collision of the vehicle, the foot Xa is moved to the arrow β by the guide portion 282d. Is moved forward and upward, and the toes are guided to a hanging portion 62a at the lower portion of the instrument panel 6 as indicated by a two-dot chain line in the figure. For this reason, it is possible to prevent the foot of the occupant X from getting over the front end of the tread plate 82 and interfering with the dash panel 4 as in the above-described embodiments.

  In the present embodiment, since the front end of the guide portion 282d is not supported by the lower portion of the instrument panel 6 as described above, the instrument corresponding to the grooves 62b and 162b is provided as shown in FIG. It is not necessary to form the lower part of the panel 6. For this reason, the lower surface of the under cover 62 (hanging part 62a) can be made into a simple shape.
