    摘要: A height adjustment mechanism is disclosed that includes a pedestal height variability mechanism. The pedestal height variability mechanism includes a first member and a biasing mechanism. The biasing mechanism is configured to hold the first member in a first position. The first member has a first end and a second end opposite the first end. The biasing mechanism has a first portion attached to the first member adjacent the first end of the first member. The biasing mechanism also has a second portion attached to the first member adjacent to the second end of the first member. Preferably, a second member is also provided that is moveably attached to the first member. The second member may be configured such that movement of the second member actuates height adjustment of a chair.

    摘要: A chair having a seat rotatably attached to a tilt spring portion of a tilt mechanism such that the tilt spring is activated by movement of the seat. A backrest and/or the seat can be rotatably connected to the tilt mechanism by parallel arm arrangements which permit the seat and backrest to tilt relative to each other. A tilt limiter can have a magnetic member which facilitates full movement of the tilt limiter between free and locked positions, and which creates an audible indication of full movement of the tilt limiter. The seat/backrest can be made from a flexible mesh material secured to a rigid overmolding which surrounds and is attached to an inner frame of the seat/backrest wherein an outer surface of the overmolding forms an outer surface of the seat/backrest frame and attachment of the overmolding causes the inner frame to stretch the mesh to a final condition.

    摘要: A chair tilt control mechanism for a pedestal base chair having a chair control housing mounted on the pedestal chair base and pivotally supporting a chair seat support member. A laterally movable front stop member retained within the chair control housing is movable and contacts the front flange of the chair seat support member and limits the pivotal movement of the chair seat support member to predetermined angular positions with respect to the chair control housing and the floor supporting the chair. Also disclosed is a lever member adapted to lock the chair seat support member in one or more predetermined angular positions. Also disclosed is a hollow plastic pivot pin for pivotally connecting a chair control housing to a chair seat support member.

    摘要: A tilt control mechanism that is mounted to the underside of a chair bottom, and permits the user or sitter to selectively control the chair height, as well as the degree of chair tilt. A tension adjustment mechanism is provided to permit the user to change the amount of spring tension exerted against the chair bottom when the chair is tilted back. Finally, a structural support is provided which interconnects the seat bottom with the tilt mechanism, and transmits downwardly-exerted weight to the mechanism. Each of these four mechanisms comprises a number of parts seated within a die cast enclosure or housing.
