工夫されていなかった。2. Description of the Related Art As shown in FIG. 24, a petal mechanism such as a brake petal or a clutch petal is disposed in a vehicle cabin. The petal mechanism portion includes a petal arm 27 having a base end side pivotally supported by the vehicle and having a petal tread plate 6f at a distal end side, a master cylinder 28 connected to an intermediate portion of the petal arm 27, and the like. The petal operation is performed by placing the lower limb 29 on the petal tread 6f as shown in the figure and applying a pedaling force to the petal tread 6f by the lower limb 29. When a large external force is applied to the front end side of the vehicle at the time of a vehicle collision or the like, the vehicle is deformed, and a large force acts on various parts of the occupant with this deformation. For this reason, various occupant safety devices are also employed in the prior art. On the other hand, the lower limb 2 directly on the petal tread 6f of the petal such as a brake petal
A large force is applied to the ankle 29a, particularly to the ankle 29a when the external force is applied, but this protective means has not been sufficiently devised in the past.

し下肢２９と足首２９ａに傷害を与える恐れがある。During normal operation, the brake petal is not operated except during the stopping operation of the vehicle, during the speed reduction, and during the slow running. On the other hand, when analyzing the movement of the occupant at the time of a vehicle collision or the like, if the occupant feels danger, the occupant performs an operation of pressing the brake petal and also depresses the petal to extremely increase the pressing force. Although an external force at the time of a collision or the like acts greatly on the petal tread, the external force acts on the lower limb 29 because the lower leg 29 of the occupant strongly steps on the petal tread. That is, a large external force acts on the lower limb 29. For this reason, especially the ankle 29a of the lower limb 29
(A portion indicated by a two-dot chain line circle in FIG. 24) may exert a large force to cause injury to the lower limb 29 and the ankle 29a.

However, in any case, the petal arm simply moves in the front-rear direction when the external force is applied. However, the petal treading force cannot be controlled to an arbitrary value, and in particular, the petal treading force cannot be freely controlled to a certain value or less. In addition, it does not directly protect the lower limbs, particularly the ankles, and the reliability of lower limb protection is not sufficient.

And the fitting portion on the base end side of the second petal arm is fitted on the distal end side of the first petal arm. During normal operation, both petal arms function as a petal arm having an integral structure. However, when a large external force is applied such as at the time of a vehicle collision, the fitting portion is completely or partially deformed, and the fitting of the second petal arm into the first petal arm is completely or partially released. As a result, an increase in the pedal effort can be avoided. Note that, by shifting the fitting portion and the petal tread, the deformation of the fitting portion when an external force acts is more easily and reliably performed. Further, by forming the engaging portion in the fitting portion and engaging the engaging portion with the engaging portion of the first petal arm, the deformation of the fitting portion can be performed more easily and reliably.

伝える。Next, the operation of the lower limb protection petal apparatus 1 according to the present embodiment will be described with reference to FIG. During normal operation, the first petal arm 2 and the second petal arm 3 are held in the engaged state shown in FIGS. 1 and 3 even if the pedaling force P acts on the petal tread plate 6. That is, the second petal arm 3 is fitted to the fitting portion main body 7 of the first petal arm 2, and the first petal arm 2 and the second petal arm 3 operate integrally. In this case, since the engagement engagement piece 9 riding on the engagement groove 4 is located at a position substantially coinciding with the front end of the fitting portion main body 7, almost no upward force acts on the engagement engagement piece 9 but on the platform 5 a of the engagement pedestal 5. The upward force Fa is applied to the engagement engaging claw 10
Acts. However, the engaging and engaging claw 10 has such a strength that it is not deformed by the force of Fa, so that it operates as an integrated structure of the first petal arm 2 and the second petal arm 3 as described above, and the pedaling force P is increased by the first force. Inform the petal arm 2 side.

ことによりこの最大踏力の値はコントロールされる。Next, when a large external force is applied, such as at the time of a vehicle collision, the pedaling force P increases, and the force of Fa increases accordingly. If this value exceeds the bending strength of the engagement engaging claw 10, The engagement engaging claw 10 starts to deform. Therefore, the fitting portion 7 of the second petal arm 3 starts to separate from the first petal arm 2, and the pedaling force P does not increase any more from the start of the deformation of the engagement engaging claw 10. That is, even if the external force becomes large, the petal treading force does not increase, and the force applied to the lower limb does not increase beyond a certain value. Therefore, the safety of the lower limb is maintained. Since the maximum value of the pedaling force P substantially corresponds to the strength of the engaging pawl 10, the value of the maximum pedaling force is controlled by appropriately setting the strength of the engaging pawl 10.

The first petal arm 2a of the lower limb protection petal device 1a has an engaging recess 11, which is one of the engaging portions, and engaging grooves 12, 12 formed on the right and left side surfaces on the distal end side. On the other hand, the second petal arm 3a having the petal tread 6a has a fitting portion main body 8a, which is one of the fitting portions 7a fitted into the engaging recess 11, and one of the engaging portions engaging with the engaging groove portion 12.
Is formed. The petal tread 6a is arranged at a position shifted by a dimension b from the right side surface of the first petal arm 2a in the drawing. Further, the distance between the engagement fixing claw 10a and the front end surface of the engagement concave portion 11 is set at a distance H. With the structure described above, the lateral force of F R = P · b / H acts on the engagement engaging claw 10a by the action of the pedaling force P, and the force of F R is equal to or less than the bending strength of the engagement engaging claw 10a. The first petal arm 2a and the second petal arm 3a operate as an integral petal arm. When F R exceeds a certain value, the engagement engaging claw 10a opens and the pedaling force P does not increase any more. As described above, substantially the same effects as those described above can be obtained.
