ABSTRACT:
Brake designed to be connected to a brake cable (15), comprising a ratchet plate (1, 2) fixed to the floor of the vehicle, a pawl (4) designed so as to interact with the ratchet plate (2), and a handgrip lever (6) equipped with a push-button (18) associated with the pawl; it comprises a cassette casing (5) mechanically integral with the lever, containing the ratchet plate (1, 2) and the pawl (4), articulated on the ratchet plate and on the end of the brake cable (15). The cassette (5) is formed from two end plates (5a) between which are arranged the ratchet plate (1) and the pawl (4), and which are fixed to the lever (6) Because the lever is split into a grip lever (6) and a cassette casing (5), it is possible to make only the latter from sheet metal so as to enable it to withstand forces, whilst the lever (6) can be made from plastic molded into various shapes depending upon the desired aesthetics. This arrangement reduces the weight and the cost price of the brake, and permits automatic assembly of its constituent parts, with the exception of the plastic lever (6).
