Pedal assembly supporting structure for automobile

摘要

In a supporting structure for a brake pedal assembly 8 pivotally mounted for rocking motion on the rear surface of a dash panel 1 of an automobile through a first bracket 2, a front portion of the first bracket 2 is fixed to the dash panel 1 and a rear-end upper portion thereof is coupled to a second bracket 5 fastened to an instrument panel member 7 as a car body member in a cabin so as to be disengageable by the application of a load of automobile collision above a predetermined level. The brake pedal assembly 8 is pivotally mounted for rocking motion to the first bracket 2. On the underside of the second bracket 5, an inclined guide surface 5a is provided which abuts against the upper end of the brake pedal assembly 8 when the coupling between the first and second brackets 2, 5 is disengaged in an automobile collision so that the first bracket 2 moves backward together with the brake pedal assembly 8. The inclined guide surface 5a guides the brake pedal assembly 8 in its downward movement through its abutment against the inclined guide surface 5a. This ensures to prevent the brake pedal assembly 8 from moving backward in an automobile collision while providing a simple and highly reliable structure.
