A seat recline mechanism for, and method of controlling motion of a first assembly relative to a second assembly within a seating assembly includes a mechanism having first and second bearings for attaching to the first assembly, and a hub for attaching to the second assembly. The hub includes first and second inclined surfaces, the second inclined surface being oppositely-facing relative to the first inclined surface. In use, the first bearing is arranged to act against the first inclined surface and the relative position of the first bearing with respect to the first inclined surface is adjustable; and the second bearing is arranged to act against the second inclined surface and the relative position of the second bearing with respect to the second inclined surface is adjustable. One or more such mechanisms are provided for the seating assembly.

The invention relates to a chair (10) having a base (40) and a support (20), articulated thereon, that is coupled to a seating surface (11) and supports the latter, the seating surface (11) being connected to the support (20) rotatably or pivotably around a rotation axis (30) between a sitting position and a raised position, and the support (20) comprising at least one receiving region (28, 29) for aligned abutment of a juxtaposed chair (10) of identical design. Provision is made in this context that in the raised position, the seating surface (11) is pivoted out of the receiving region (28, 29) of the support (20) and exposes it. The result is to create a chair (10) that, for storage, can be juxtaposed in space-saving fashion with chairs (10) of identical design.

A fixing device includes an encircling element having left and right lateral sides and an intermediate portion that is formed with a notch and that is bent to form two limiting apartments at two sides of the notch, each limiting apartment having left and right walls extending integrally and transversely from a longitudinal axis of the encircling element and a middle wall interconnecting the walls that define an opening accessible only from a direction that is the same direction, each of the left and right lateral sides is formed with a retainer stub; a sluice gate having two notches disposed on the retainer stubs for denying access into the apartments; and a locking member extending through a through hole in the sluice gate and the notch in the encircling element for preventing untimely disengagement of the sluice gate from the encircling element.

Beam mounted chair assemblies may include at least two standards supported on a floor, a beam secured to, and supported by, the standards, and a plurality of chair assemblies secured to, and supported by, the beam. Chair assemblies may be secured to a beam via associated chair brackets. Chair brackets may include chair seat pivots that pivotally secure a chair seat in proximity to a chair back such that the chair seat may pivot between an up and a down position. Chair brackets and standards may be secured to a beam such that the chair brackets and standards may be linearly positioned along a full length of the beam without interfering with one another. The beam mounted chair assemblies may include electrical power and/or data wiring and associated components.
