Storage of chairs when not in use, for instance in halls used by various groups, is a common problem which has been addressed by providing chairs that are stackable upon one another. Usually, this requires the chair to be composed of sloping legs and a sloping backrest, such that the seat of a lower chair can fit between the legs of an upper chair, and the backrest of the upper chair can rest on the backrest of the lower chair. It is desirable to be able to stack chairs with as small a vertical displacement as possible, usually limited by the depth of the seat, which is typically substantially horizontal. For instance, the base of an upper seat may sit (when stacked) on the upper portion of a lower seat. However, these chairs are usually mass produced and so designed to fit the average shape, which is not accommodating for a lot of people. The present invention provides a chair where seat 13 height, back 3 angle, seat 13 tilt and seat 13 roll are adjustable.

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 seatback assembly structured to at least partially support a seated individual on a wall, specifically but not exclusively, a pre-existing or newly constructed wall configured to facilitate one or more individuals to sit on an exposed portion thereof. The seatback assembly includes a back support orientation to and extending along the length of the wall and a connector assembly disposed in an operative position interconnecting the back support to the wall. The connector assembly includes at least one or a plurality of brackets, each including a base and a support segment and an anchor interconnecting each of the one or more brackets at least partially on the interior of and in stabilizing relation to the wall. A supporting orientation of the back support includes it connected to the wall in receiving, engageable relation to a seated individual.

The present invention relates to a feedback device and a method of providing thermal feedback using the same. A method for calibration of an intensity of a thermal feedback of a feedback device may comprise: outputting the thermal feedback in order from a weak intensity to a strong intensity among a plurality of intensities of the thermal feedback; obtaining a first user input; setting an intensity of the thermal feedback outputted at the time of the obtaining the first user input to a lowest intensity of the thermal feedback; obtaining a second user input; setting an intensity of the thermal feedback outputted at the time of the obtaining the second user input to a highest intensity of the thermal feedback; setting at least one intermediate intensity; and outputting the thermal feedback by using the lowest intensity, the highest intensity and the at least one intermediate intensity.

The invention provides a novel recliner chair suitable for a cinema, which relates to a chair used in a cinema, a conference hall and other public places, in particular to a chair mounted on stepped ground of the above occasions. An underframe and an electric recliner chair body fixed on the underframe are included. The underframe includes a horizontal frame and a vertical frame, and the horizontal frame and the vertical frame are arranged in a “T”-shaped manner. The recliner chair in the invention is suitable for the stepped ground, and is convenient to mount and firm to fix. And the floor area ratio per unit area may be improved, so that the designed accommodation number of people in the whole cinema becomes larger.

A chair can be configured for synchronized movement with visual content, such as a video game or movie, presented on a display. The chair can include a seat portion. A plurality of actuators can be operatively positioned to cause a movement of the seat portion. The actuators can include one or more shape memory material members. Each of the actuators being configured such that, when an activation input is provided to the one or more shape memory material members, the one or more shape memory material members change from a first configuration to a second configuration and cause the actuator to morph into an activated configuration. One or more processors operatively connected to selectively activate one or more of the actuators by causing the activation input to be provided to the one or more shape memory material members of at least one of the actuators.

Disclosed is a modular seat for aircraft. The system has a frame that is able to be interconnected with other frames laterally. Since each lateral frame has the same pivot points (when viewed from the side), the linked seats rotate together. The seats also include buckle lugs which enable a particular seat to be used on either side of the aircraft.

A seat connection mechanism having a bracket portion which is metal and includes a pivot area, an opening and a channel. A metal pin portion includes a pin and a stop portion, the pin rests in the pivot area such that the shelf portion inhibits movement of the pin portion along the pin's rotation axis, the pin configured to rotate within the pivot area about a rotation axis. The channel in the bracket portion arranged to pass adjacent and through an area of the center pivot, the channel arranged such that the stop portion of the pin portion are insertable into the channel through the opening at an insertion angle to allow the pin to rest in the pivot area and such that when the pin rotates within the center pivot, the stop portion of the pin portion moves within the bracket and the stop portion is configured to interact with the bracket at one or more predefined positions to stop rotation of the pin portion.
