Abstract: A chair, which has a cylinder for controlling the configuration of a chair or the seat height of a chair, is operated by a flexible cable. The flexible cable is attached to an adjustment member that is not fixedly attached to the cylinder, thereby permitting the cylinder to be replaced without replacing the adjustment member.

Abstract: An improved chair is disclosed. The chair includes: (i) a seat; (ii) a base portion connected to the bottom of the seat; (iv) an upwardly extending support frame connected to either the seat or the base; and (v) a backrest connected to the support frame by a number of fasteners. The fasteners include a resilient member located between the backrest and the support frame, such that the backrest is spaced apart from the support frame.

Abstract: A seating apparatus has a support element having an upright extending from a floor and a swing arm pivotably mounted to the upright about a generally vertical pivot axis. A work surface is secured to the upright above the swing arm, and a seat is mounted on the swing arm, the seat having a seat base upon which an occupant can be seated. The swing arm is pivotable between a stowed position wherein the seat base is tucked substantially underneath the work surface, and a deployed position wherein the seat base is substantially clear of the work surface. The seating apparatus is also provided with a flat coiled torsion spring for biasing the arm to the stowed position, the torsion spring having a first end fixed directly or indirectly to the upright and a second end fixed directly or indirectly to the swing arm.

Abstract: A backrest for use with a chair includes a support structure. The support structure has a rigid outer rim and flexible inner back support section. The support section consist of a number of generally parallel slats (vertically extending members) which seperately support parallel longitudinal sections of the person's back. Each slat produces a force against the person's back responsive to the weight placed on the slat by the person's back. As the person shifts positions, each slat moves to dynamically provide an increased or decreased force against the person's back, depending on whether the person is applying an increased or decreased force against the slat.

Abstract: A backrest for supporting a person's back having a front surface and a rear surface has a flexible support section having a fixed end which is mounted to a support structure and a free end which is displaceable vertically with respect to the fixed end, the support section is configured to be compressed and displaced forwardly when the free end is moved towards the fixed end. In one embodiment, an adjustment member is drivingly connected to the free end; and, a detent member for selectively receiving the adjustment member in one of a plurality of positions, the support member biasing the adjustment member into retaining engagement with the detent member due to the compression of the flexible support member by the displacement of the free end towards the fixed end. In another embodiment, a cam mounted off-center on a shafted controls the compression of the support structure.

Abstract: A molding station has a housing support and a housing. The housing has a generally horizontal axis, a plurality of mold cavity enclosures and a plurality of sides. The housing is rotatably mounted to the housing support about the generally horizontal axis. The mold cavity enclosures are circumferentially positioned about the axis in at least some of the sides. Each mold cavity enclosure defines at least one mold cavity.
