Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a vehicle heel stopper device that prevents a heel portion of a passenger's foot placed on a floor surface of a passenger compartment from moving forward during a collision.
[0002]
[Prior art]
The floor surface of the passenger compartment is generally formed flat, and the heel portion of the foot can be placed at an arbitrary position on the floor surface when operating a pedal such as an accelerator pedal.
By the way, at the time of a frontal collision, an occupant's lower limb may move forward due to inertia. In this case, the heel portion of the foot enters between the pedal and the floor surface, and the angle formed by the foot and the shin is reduced, which may put a burden on the occupant's lower limb.
[0003]
As a countermeasure for this, conventionally, according to JP-A-8-164782, a stopper portion that rises from the floor surface of the passenger compartment is provided, the heel portion of the occupant's foot is received by the stopper portion at the time of collision, and the heel portion is further forward. It is known to be able to prevent movement.
In this case, the floor panel of the vehicle body is bent upward to form a stopper portion, or a member to be a stopper portion is attached on the floor surface.
[0004]
[Problems to be solved by the invention]
The conventional example has a problem that the stopper portion always rises from the floor surface and the degree of freedom of movement of the occupant's feet is restricted.
In view of the above, the present invention provides a heel stopper device for a vehicle that can prevent the heel portion from moving forward in the event of a collision without impairing the freedom of foot movement during normal operation. It is an issue.
[0005]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention provides a vehicle heel stopper device that prevents a heel portion of a passenger's foot placed on a floor surface of a passenger compartment from moving forward at the time of a collision. It is provided to protrude on the floor surface only occasionally.
[0006]
In this case, the stopper member may be configured by an airbag that inflates at the time of collision and protrudes between the floor surface and the pedal, a spring member that urges the stopper member in the protruding direction, and the stopper member as the spring member. It is also possible to provide locking means for locking at the non-projecting position against the urging force, and the locking means may be configured to unlock the stopper member by an impact at the time of collision.
[0007]
Furthermore, since the toe board at the front end of the passenger compartment is deformed rearward in the event of a collision, the stopper member provided so as to protrude and retract on the floor surface is projected on the floor surface via the interlocking mechanism by the rearward deformation of the toe board. May be. In addition, an actuator that operates at the time of a collision may be provided, and the stopper member may be protruded on the floor surface via an interlocking mechanism by the operation of the actuator.
[0008]
In any case, since the stopper member does not normally protrude on the floor surface, the freedom of movement of the occupant's feet is not restricted. At the time of collision, the stopper member protrudes on the floor surface, so that the heel portion of the foot is received by the stopper member, and the heel portion is prevented from moving forward.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Referring to FIG. 1, reference numeral 1 denotes a floor panel of an automobile body. A carpet 2 constituting a floor surface 2 a of a passenger compartment is laid on the floor panel 1. In addition, a toe board 3 that rises obliquely forward from the front end of the floor panel 1 and a dashboard 4 that extends upward from the upper end of the toe board 3 are provided to form a bulkhead in the lower front part of the passenger compartment. A pedal 5 such as an accelerator pedal operated by the foot a is arranged.
[0010]
Further, a recess 6 is provided in a lateral position that matches the pedal 5 at the bottom of the toe board 3, and an airbag 7 containing a gas generator 7a is accommodated in the recess 6, and the opening of the recess 6 is covered with a cover 7b. Covering.
[0011]
At the time of a collision, the explosive in the gas generator 7a is ignited by a signal from the acceleration sensor and the airbag 7 is inflated. As shown in FIG. 1B, the airbag 7 breaks through the cover 7b and is on the floor surface 2a. It protrudes from the front and advances into the space between the floor surface 2a and the pedal 5. Therefore, the airbag 7 functions as a stopper member that receives the heel portion b of the foot a of the occupant, and the forward movement of the heel portion b due to inertia is prevented.
[0012]
FIG. 2 shows a second embodiment. In this embodiment, a plate-like stopper member 8 is locked to an opening of a recess 6 at the bottom of the toe board 3 by a claw portion 8a serving as a locking means, and the stopper member is fixed to the recess 6. A spring member 9 is housed that biases 8 toward the floor surface 2a , that is, backward. In the illustrated example, the spring member 9 is formed of a cylindrical body having a compressible bellows portion, but the spring member 9 may be formed of a coil spring or the like.
[0013]
According to this, the stopper member 8 is normally locked against the urging force of the spring member 9 at a non-projecting position that covers the opening of the recess 6. At the time of collision, the claw portion 8a is broken by an impact and the stopper member 8 is unlocked, and the stopper member 8 is moved forward on the floor surface 2a by the urging force of the spring member 9 as shown in FIG. Project from the floor surface 2a and enter the space between the pedal 5 and the floor surface 2a . Accordingly, as in the first embodiment, the heel portion b of the occupant's foot a is received by the stopper member 8, and the forward movement of the heel portion b due to inertia is prevented.
[0014]
FIG. 3 shows a third embodiment. In this embodiment, a recess 1a is formed in a portion of the floor panel 1 located below the pedal 5, and a plate-like stopper member 10 is provided in the recess 1a in the front-rear direction. The intermediate pivot 10a is attached so as to be tiltable. The stopper member 10 is normally held in a horizontal posture that is substantially flush with the floor surface 2a formed of the carpet 2 by the protrusion 11 in the recess 1a that abuts the rear end thereof.
[0015]
By the way, at the time of a frontal collision, the toe board 3 is deformed so as to rise rearward. As a result of this deformation, the stopper member 10 is tilted rearward as shown in FIG. 3B via the interlocking mechanism 12 so that the rear end portion of the stopper member 10 protrudes from below on the floor surface 2a . . Thus, at the time of collision, the heel portion b of the occupant's foot a is received by the stopper member 10, and the heel portion b is prevented from moving forward.
[0016]
The interlocking mechanism 12 of the third embodiment is configured by a link 12 b having an upper end pivotally attached to a bracket 12 a fixed to the upper portion of the toe board 3 and a lower end pivotally attached to the front end of the stopper member 10. When the toe board 3 is deformed so that it rises rearward with its lower end as a bending point, the pivot point 12c at the upper end of the link 12b is displaced along a circle centering on the lower end of the toe board 3, but the lower end of the link 12b is pivoted. Since the landing point 12d is located above the lower end of the toe board 3, the pivoting point 12d is pushed down via the link 12b, and the stopper member 10 is tilted rearward.
[0017]
The interlocking mechanism 12 is not limited to this. For example, on the floor panel 1, a bell crank-shaped lever having one end connected to the toe board 3 and the other end connected to the rear end of the stopper member 10 is pivotally supported. It is also possible to tilt the stopper member 10 rearward and upward by the rotation of the lever due to the rearward deformation.
[0018]
FIG. 4 shows a fourth embodiment. In this embodiment, a plate-like stopper member 13 is tiltable by a pivot 13a at its front end in a recess 1a formed in a portion of the floor panel 1 located below the pedal 5. Installed on. The depression 1a extends over the rear of the arrangement portion of the stopper member 13, and a cylinder type actuator 14 containing a gunpowder that is ignited by a signal from the acceleration sensor at the time of collision is fixed to the rear portion of the depression 1a. Yes. The rear part of the recess 1a is covered with a cover plate 1b.
[0019]
The stopper member 13 is normally held in a horizontal posture that is substantially flush with the floor surface 2 a formed of the carpet 2, but is tilted rearward and upward via the interlocking mechanism 15 by the operation of the actuator 14 in the event of a collision. As shown in FIG. 4B, the rear end portion of the stopper member 13 protrudes from below on the floor surface 2a . Thus, at the time of collision, the heel portion b of the occupant's foot a is received by the stopper member 13, and the heel portion b is prevented from moving forward.
[0020]
The interlocking mechanism 15 includes a rotating body 18 to which a pin 17 that engages with a cam groove 16 formed in the stopper member 13 is attached, and a wire 19 having one end connected to the rotating body 18. By pulling the wire 19, the rotating body 18 is rotated in the clockwise direction in FIG. 4, and the stopper member 13 is tilted backward via the cam groove 16 by the pin 17.
[0021]
The interlocking mechanism 15 is not limited to this. For example, as in the fifth embodiment shown in FIG. 5, a slope 20 is formed on the lower surface of the stopper member 13 that is inclined downward toward the front, and is recessed. 1a, a wedge piece 21 is disposed so as to be movable back and forth, and the actuator 14 attached to the front of the arrangement portion of the stopper member 13 is actuated by pulling the wedge piece 21 forward via a wire 22, and the wedge piece 21 via an inclination 20 The stopper member 13 may be tilted backward as shown in FIG.
[0022]
Further, as in the sixth embodiment shown in FIG. 6, the stopper member 13 is attached to the recess 1 a so as to be raised and lowered by the pivot 13 a at the front end, and the wire 23 having one end wound around the pivot 13 a is connected to the actuator via the guide pulley 24. 14, and the stopper member 13 may be erected as shown in FIG. 6B by pulling the wire 23 by the operation of the actuator 14.
[0023]
Moreover, although the said 1st thru | or 6th embodiment has prevented the heel part b of the passenger | crew's foot a who operates the pedal 5 from moving forward, the foot which does not operate the pedal 5, for example, an automatic vehicle In order to prevent the driver's left foot and passenger's foot from hitting the toe board 3 at the time of a collision, the floor portion on the left front of the driver seat and the floor portion on the front of the passenger seat protrude on the floor surface 2a at the time of the collision. A stopper member that receives the heel portion of the foot may be provided.
[0024]
【The invention's effect】
