Brake pedal assembly
A pedal assembly mounted to a vehicle includes, a pedal arm having an upper portion and a lower portion and a striker bracket pivotally connected to the upper portion of the pedal arm where the striker bracket further removably connected to the lower portion of the pedal arm. A first positioned is defined before a collision where the striker bracket is connected to the lower portion of the pedal arm. A second positioned is defined after a collision where the striker bracket rotates away from the lower portion of the pedal arm.
1. A vehicle pedal assembly, comprising:
a support within an interior of the vehicle and defining a first pivot point;
a pedal arm pivotally secured to said support, said pedal arm including an upper portion and a lower portion;
a striker pivotally mounted about a second pivot point on said upper portion a spaced distance from said first pivot point, an edge of said striker contacting said support concurrent with an underside of said striker contacting an opposing upper edge of said lower portion during normal operation of said pedal arm;
said striker further having an irregular boomerang shape, with a narrowed and indented portion defining said contact edge with said first pivot point; and
upon an impact event exerted upon said striker, said striker being caused to displace about said second pivot point away from said support and said lower portion, allowing said lower portion to rotate about a third pivot point established with said upper portion.
2. The pedal assembly as described in claim 1 , said striker further comprising a pin slidable in an elongated slot configured in said upper portion to define a range of rotation of said striker about said second pivot point.
3. The pedal assembly as described in claim 2 , further comprising a shear pin extending between said upper portion and said striker during normal operation, said shear pin fracturing upon the impact event.
4. The pedal assembly as described in claim 1 , further comprising a push rod extending from said upper portion and defining a support location for said lower portion during normal operation, rotation of said lower portion being in a direction away from said push rod.
