The vehicle brake pedal device includes a pedal bracket fixed to a partition wall, a brake arm and a coupling arm assembled to the pedal bracket, a clevis and a movable plate assembled to the coupling arm, and a fixed member and a coupling bracket assembled to a vehicle body component. In the event of a front collision of the vehicle, the pedal bracket is moved backward, and the movable plate is brought into abutment against the fixed member to rotate. As a result, a push part of the movable plate is brought into abutment against the clevis, and a breakable part of the clevis is broken so that the clevis and the coupling arm are decoupled from each other. Then, the coupling arm is rotated forward with respect to the pedal bracket.

Provided is a vehicular operation pedal device having a fail-safe function to prevent backward movement of a step portion of an operation pedal mechanism at the time of a vehicle collision. A brake pedal device (1) includes a protrusion (90) which performs rotation restriction for preventing a rotating member (50) from rotating about a rotating shaft portion (14), and on which a restricting load (F2) acts by the rotation restriction. During the rotation restriction by the protrusion (90), a second load acts as the restricting load (F2) when a step portion (24) of an operation pedal mechanism (20) is fully stepped forward of a vehicle, and when the restricting load (F2) is greater than the second load, the rotation restriction is released due to deformation of the protrusion (90) by shearing or bending.

Embodiments described herein are directed to a pedal assembly. The pedal assembly includes a housing, a pedal arm, a retaining member, and a block. The pedal arm has an upper end. The upper end is pivotally coupled to the housing. The retaining member is slidably engaged within the housing. The retaining member has a first angled portion. A portion of the retaining member in communication with the upper end of the pedal arm. The block is slidably mounted within the housing and perpendicular to the first angled portion of the retaining member. The block has a second angled portion that is complimentary to the first angled portion. Upon an impact, the second angled portion slidably engages with the first angled portion, which causes the retaining member to move and release the upper end of the pedal arm from the housing.

Provided is a vehicle operation pedal device comprising: an operation pedal provided with a depressing part; a pair of upper support members anchored to a dash panel; a pair of lower support members anchored to the dash panel and also anchored to the pair of upper support members; an upper center support member bridging the pair of upper support members; and a connection hole for rotatably supporting, relative to the operation pedal, an operating rod protruding from the dash panel toward a vehicle rear side. The upper center support member comprises a sliding receiving part. The pair of upper support members comprise escape holes.

A redundant mechanical control system incorporates a jam override subsystem to enable a breakout or break-away feature of the redundant mechanical control system. The jam override subsystem includes a spring and detent system to apply an axial force to a portion of an interconnect. The interconnect mechanically links a first portion of the redundant mechanical control system with a second portion. When a failure occurs, rendering inoperable the first portion or the second portion of the redundant mechanical control system, the axial force of the spring and detent system is overridden by a compression or extension force of the operable portion of the redundant mechanical control system.
