Abstract: An adjusting mechanism for a support element included in a seat and pivotable in the vertical plane. The mechanism comprises a fastening element (1) to be mounted on a seat or a separate body member and provided with a transverse through-hole (10) for a fulcrum pin facilitating the pivotable fixing of a support element (2), and a fastening member (3) included in the support element (2) and provided with a through-going opening (8) for said fulcrum pin. The opening (8) included in fastening member (3) is made elongated and one end thereof is provided with a bushing member (6) receiving said fulcrum pin and adapted for a relative movement in the longitudinal direction of opening (8) towards the other end of said opening (8). The opening (8) is further provided with a spring element (7) applying an impulsive force between bushing (6) and fastening member (3).
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.
