A seat with self-stowage capability is provided. The seat includes a seat pan lever which is rotatable between stowed and open positions, a fixed seat structure and an elastic assembly. The fixed seat structure includes an annulus. The elastic assembly includes a damper and an arc-spring disposable within the annulus to permit first rotations of the seat pan lever from the stowed position to the open positions and to urge second rotations of the seat pan lever from the open positions to the stowed position.

An improved virtual reality system comprises a chair 110 integrated with a pedestal 120, which contains a motion platform 150 and base 160. The chair 110 can be rotated continuously in the yaw axis by a stepper motor 230 and substantially in the pitch axis by an additional stepper motor 240 in coordination with the content of the VR display as directed by a chair controller located on the motion platform 150.

A beam seating assembly has a frame supporting a seating surface. A beam secures to a first support and extends in a longitudinal direction. A channel is located the beam free of the first support. The frame has a lower portion with a connector that is insertable into the channel transverse to the longitudinal direction and the connector, once inserted into the channel, is retained from removal out of the channel in a direction. The connector is insertable into a first portion of the channel and a second portion of the connector rotatable into a second portion of the channel and then slidable away from the first portion such that the first and second portions of the connector are retained within the channel but are slidable in the longitudinal direction until the connector is fixedly secured to the beam. The frame is made in certain aspects from a flat plate.

A tilting mechanism (1) for chairs includes a support frame (2), a structure (4) rotationally coupled to the support frame. An elastic system (80) is interposed between the support frame and the structure to counteract a reaction to the tilting of the structure from an at-rest position to a tilted position. An adjustment system (20) is capable of varying the reaction to the tilting. The elastic system (80) includes at least one elastic element (12) and a first and a second stop element (81, 82) fastened at respective longitudinal end portions of the elastic element, respectively. In the at-rest position, the first and second stop elements are in contact with each other, and the elastic element (12) is in a deformed configuration and generates a residual elastic force that is at least partially released on the first and second stop elements.

A vehicle seat hinge assembly includes a first pivoting member that defines a first axis and is coupled to a first bracket disposed on a vehicle floor. The hinge assembly also includes a second pivoting member that defines a second axis and is disposed on a seat. The first pivoting member is pivotable about the first axis between at least first and second positions. The second pivoting member is pivotable about the second axis between at least fixed and released positions.
