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.

The invention relates to an actuator assembly for an adjustable seating or lying furniture item, in particular for an adjustable bed or an adjustable comfortable armchair, comprising a spindle that can be activated by means of a drive for causing axial rotation, which is mounted in a stationary manner. The actuator assembly also comprises a sliding block mechanically coupled with the spindle, the sliding block can be moved parallel in relation to a longitudinal axis of the spindle when said spindle is activated. The actuator assembly also comprises a coupling element mounted in a manner allowing it to be moved in relation to the spindle with a first slotted guide, in which the sliding block is at least partially guided in such a way that the coupling element is shifted when the spindle is activated, in order to move a segment of the adjustable seating or lying furniture item that can be mechanically coupled with the coupling element. The invention further relates to an adjustable seating or lying furniture item.

The system according to the present disclosure is used to support a surgeon. It includes an operating chair and a restraining device for the surgeon. The restraining device has a harness system which comprises at least a first and a second restraining belt which are connected to at least a first and a second spaced-apart suspension point of a traction device, the traction device being configured to establish the distance between the suspension points. The system according to the present disclosure improves the wearing comfort of the restraining device for the surgeon, since it prevents the restraining harnesses of the harness system from constricting under tensile load, which can lead to unpleasant and undesirable pressure sensations in the upper body area of the surgeon.

The seated inversion table is provided having a support frame assembly, and a seat back assembly, and a seat cushion assembly tiltably mounted on the support frame assembly. The seat back assembly connects to the seat cushion assembly and connects to a rotating frame assembly through a lower connecting tube assembly. The rotating frame assembly is tiltably mounted on the seat cushion assembly and is adjustably mounted on a foot-clamping frame. With a front swinging rod of the seat cushion assembly tiltably mounted on the support frame assembly, a range of an inversion angle is restricted and thereby the seated inversion table may not over tilt.

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.

A virtual-reality navigation controller includes a base, a seat, a vertical support to support the seat on the base, and a rotatable connector between the seat and the vertical support to tilt the seat about a rotational center of the rotatable connector in response to directional forces exerted by a user seated on the seat. The virtual-reality navigation controller further includes a motion-detection controller to measure pitch corresponding to the tilt of the seat resulting from the directional forces.
