<Operation of First Embodiment>
Next, the operation of the leg protection structure according to the first embodiment of the present invention will be described with reference to FIGS. 3 and 4.
Just before the vehicle collides, the driver D puts the leg part D1 on the foot part 1a of the brake pedal 1 to step on the brake device and decelerates the vehicle, as shown in FIG.

  However, when the vehicle collides, as shown in FIG. 4, the panel 4 may be subjected to an impact force in the arrow Y direction from the back surface side to the vehicle interior side. Then, the panel 4 is deformed to the vehicle interior side by the impact force, and the leg protection structure A installed on the panel 4 is moved to the vehicle interior side to contact the pedal arm 1b and the foot step 1a. Let

  At this time, the pedal arm 1b is pressed by the soft material 52 when the impact absorbing portion 5 comes into contact with the pedal arm 1b, and is deformed so as to be recessed into the soft material 52 and the hard material 51, and the impact force is attenuated and transmitted. The foot part 1a is transmitted in a state where the impact force is absorbed and attenuated by being deformed so that the soft material 52 collides with the back surface and sinks.

In this way, although the impact force applied to the brake pedal 1 is attenuated, as shown in FIG. 4, a moment M (torsional moment) in the left-right direction is applied to the leg portion D1. For example, when a leftward moment M is applied, the leg portion D1 moves to the left on the stepped portion 1a and tilts toward the panel 4, and the side portion D2 presses the shock absorbing portion 5.
When the side part D2 is in contact with the shock absorbing part 5 in a state where the leg part D1 is inclined, the side part D2 is in contact so as to sink into the soft material 52 in the upper part where the inclined surface 51a of the hard material 51 is formed, Impact force is absorbed. The impact absorbing portion 5 receives and supports the impact force and the leg portion D1 by the support portion 5a because the impact force is a force in a direction substantially orthogonal to the inclined surface 51a. The impact can be attenuated by the lower soft material 53.

As a result, when the left moment M is applied in the event of a collision, the leg D1 of the driver D is buffered by the soft materials 52 and 53 and supported by the inclined surface 51a of the hard material 51. Since the movement to the vehicle outer side direction is suppressed and the moment M in the left direction is reduced, the vehicle is held at an appropriate position.
At this time, the soft material 52 is elastically deformed into a recessed state so as to fit well with the side portion D2, and the contact area with the side portion D2 is widened. The part D1 can be protected. Note that the leg protection structure A acts similarly when a moment M acts on the leg D1 in the right direction.

And a case body 63 that holds the support plate 61 and the cover body 62.

<Support plate>
The support plate 61 is a member that absorbs an impact by plastic deformation by an impact force, and is made of, for example, a buffer material made of a metal plate such as relatively soft iron or aluminum alloy. The support plate 61 is formed with curved convex portions 61 a whose central portions are in contact with the inner surface of the cover body 62, and hook-shaped supports that are formed at both ends of the convex portions 61 a and are fitted into the inner bottom of the case body 63. Part 61b. The support plate 61 only needs to be deformed to absorb the impact, and may be made of a synthetic resin that is elastically deformed. The support plate 61 corresponds to a “deformation absorbing portion” described in the claims.

<Cover body>
The cover body 62 is a plate-like member installed on the upper surface of the impact absorbing portion 6, and both end portions are fixed to the inner wall near the opening end of the case body 63, and a notch 62 a is formed at a substantially central portion. Yes.
The notch 62a is formed in the stepping operation direction Z of the brake pedal 1 where the pedal arm 1b is disposed, and is deformed so as to expand by contacting the pedal arm 1b in the event of a collision or the like. It is a part that absorbs impact. At this time, the pedal arm 1b is formed so as to bite into the notch 62a and the support plate 61 in the shock absorber 6 is plastically deformed. The cover body 62 corresponds to a “support portion” described in the claims.

<Case body>
The case body 63 is formed of, for example, elastic metal or synthetic resin, and the support plate 61 is accommodated in the inner bottom, and the cover body 62 arranged to be placed on the support plate 61 closes the opening. Is fixed to the inner wall.

<Operation of Second Embodiment>
Next, the operation of the leg protection structure according to the second embodiment of the present invention will be described with reference to FIGS. 5 and 6.

  When the vehicle collides, as shown in FIG. 6, the panel 4 may be subjected to an impact force in the arrow Y direction from the rear surface side to the vehicle interior side. If it does so, the panel 4 will deform | transform into the vehicle interior side with the impact force, will move the leg part protection structure B to the vehicle interior side, and will contact | abut to the pedal arm 1b.

  At this time, the pedal arm 1b is pressed to the vicinity of the notch 62a of the cover body 62 when the impact absorbing portion 6 contacts, and the notch 62a is broken and deformed, and the cover body 62 bites in. In the pedal arm 1b, the shock is absorbed by the deformation of the notch 62a. Further, the pedal arm 1b is deformed by pressing the convex portion 61a of the support plate 61, and the impact is absorbed.

Thus, the impact force applied to the brake pedal 1 is attenuated by the cover body 62 and the support plate 61, but a moment M in the left-right direction is applied to the leg portion D1. For example, when a left moment M is applied to the leg portion D1, the leg portion D1 moves leftward on the foot step portion 1a and tilts toward the panel 4, and the side portion D2 presses the impact absorbing portion 6.
When the leg part D1 is in contact with the shock absorbing part 6 with the leg part D1 tilted, the side part D2 is supported by the cover body 62 and moves in the left-right direction because the cover body 62 is in the vicinity of the foot step part 1a. This is suppressed, and the left moment M is reduced, so that it is held at an appropriate position. Note that the leg protection structure B acts similarly when a moment M acts on the leg D1 in the right direction.

The power transmission mechanism 8 includes the piston portion 7b, the first and second cylinder portions 10a and 10b, the fluid 81 such as oil and air filled in the flow path, and the piston portion provided in the second cylinder portion 10b. 9b mainly. The power transmission mechanism 8 is formed such that the area of the fluid pressing surface of the piston portion 9b is smaller than the area of the fluid pressing surface of the piston portion 7b. The movement is greater than the movement distance of the shock absorber 7.
The power transmission mechanism 8 has a function of absorbing a shock by causing the fluid to flow by pressing the pedal arm 1b and causing the shock absorber 7 to move at a reduced speed in the event of a collision. The power transmission mechanism 8 corresponds to a “deformation absorbing portion” described in the claims.

<Supporting part>
The support portion 9 is a member that supports the leg portion D1 when a moment M in the left-right direction is applied to the leg portion D1 at the time of a collision or the like, and is disposed on the left and right sides of the shock absorbing portion 7, respectively.
