Unlocking device for motor vehicle brake and/or clutch pedal.

A mechanism to unlock a brake and/or clutch pedal (31) in the event of a head-on collision. Two components (1 and 2) are connected to two different points (29 and 39) of the vehicle and in the event of a collision slide against each other, thereby releasing the lever or levers. This is achieved, in case of front collision, because the housings of the bushing bearing (25) of the pedal, come apart from each other.
