ABSTRACT:
An adjusting mechanism is adapted for use with a footrest mounted in front of a seat, and a fulcrum pin to facilitate pivotable fixing of the footrest. A fastening member adapted to be included in the footrest has a pair of elongated openings for the pin. A spring biased bushing is provided at a first end of each opening and is adapted for relative movement in the longitudinal direction of the openings toward a second end of each opening. First and second guiding and locking elements are included, respectively, in the fastening member and in a fastening element through which the pin extends. Pivoting the footrest is effected by shifting it in the longitudinal direction of the openings against the spring bias toward the fulcrum pin to release the guiding and locking elements. When the footrest has been pivoted to a desired locking position, the spring bias returns it to a position in which the bushings are at the first opening ends and the guiding and locking elements are engaged. The fastening element has two take-up recesses and a locking shoulder on a back wall of each recess. The fastening member has a shaft with a forked end that is received in the take-up recesses. Each leg of the forked end has a locking cam that cooperates with the corresponding locking shoulder.
