Abstract: A device for the quick assembly and disassembly of an input rod (1) for operating a brake system and a brake pedal. A clasp (3) is secured to the input rod (1) connecting a spindle (4) fixed to the brake pedal. The clasp (3) has a guide yoke (31) which receives a retaining yoke (32) and blocking members (51,61) which maintain the retaining yoke (32) in a closed configuration with respect to the guide yoke (31). The blocking member comprise at least one lug (51) borne by the retaining yoke (32) which projects toward the guide yoke (31) and opening (61) in the guide yoke (31) which receives the lug (51) with the clasp (3) in moved to a closed configuration. On movement of the clasp (3) toward a closed configuration, parallel cheeks (325,326) of retaining yoke (31) which are squeezed together elastically expand when lug (51) enters opening (61) to lock the clasp (3) in the closed configuration.

Abstract: A pedal arrangement for a motor vehicle having a bulkhead (10) which forms a barrier between an engine compartment (C) and a passenger compartment (H) for a driver and passengers. The pedal arrangement includes a transverse brace (32) which is rigid in bending, a mount (12) for a pedal (14) which is secured to the bulkhead (10) on the passenger compartment (H) side of the bulkhead (10) and at least one rigid force-transmission element (30). The pedal (14) has a lever (16) with a first end articulated to the pedal mount (12) and a second end with an operating shoe (18) attached thereto. The force-transmission element (30) has a first end (28) articulated to the transverse brace (32) and a second end (34) which extends between the pedal mount (12 and lever (16).
