Incorporating a connection part (5) for the armrest which couples onto an attachment element (6) associated to upper horizontal tube (2), resiliently formed and fitted at the lower end thereof with an inwardly folding central extension (8) wherefrom emerges a hook (9) which may be released from opening (10) defined in attachment element (6), and is also fitted with a connection part (11) for the footrest that is formed by a slanting tubular portion (12) onto which fits the footrest (4) tube, a rear horizontal extension (13) deriving from it being provided with a vertical hole (14) on its opposite end that couples onto a stud (15) protruding from the front vertical tube (1), furthermore being fitted with an actuator (16) that exerts pressure over shank (17), which is made to move inside hole (14) and contacts stud (15), which descends vertically to dislodge the footrest (4). <IMAGE> |
