In a building equipped with a plurality of motion-enabled chairs such as a movie theatre, the vibration of the motion-enabled chairs adds up and may damage the foundation of the building especially at the resonance frequency. The present application describes a system and method for controlling the resulting vibration by introducing an alteration such as a delay or an inversion in the motion signals sent to the motion-enabled chairs. This delay causes the vibration of some motion-enabled chairs to be de-phased from the vibration of the other motion-enabled chairs. Whereby, the intensity (magnitude) of the resulting vibration is reduced. Control of the motion-enabled chairs may be done centrally through a central controller, or locally at selected motion-enabled chairs.

Method and system for reducing vibration of motion-enabled chairs

The present document describes a vibro-kinetic seating kit for providing seating to a user at a seating location in a multi-seating environment comprising other seating locations and for rendering a vibro-kinetic effect to the user. The vibro-kinetic seating kit comprises an electronic display and a vibro-kinetic platform which comprises a seat portion associated with the seating location and for providing the seating to the user; and an actuation system mechanically connected to the seat portion for rendering the vibro-kinetic effect to the user. The electronic display associated to the vibro-kinetic platform is for receiving display data and for electronically showing visual information indicative of the display data which comprises an identification tag for the seating location relative to the other seating locations in the multi-seating environment.

The present document describes a link member for providing an interface between an actuator and a seat base. The link member has a translational degree of freedom and at least two rotational degrees of freedom. The link member comprises: a joint member having a spherical surface, the joint member for attachment to one of the actuator and the seat base; a housing for attachment to the other one of the actuator and the seat base; and a slider mounted on the spherical surface and within the housing. The slider is free to move in a direction of a translational plane within the housing thereby providing the translational degree of freedom. Furthermore, the slider is free to slide on the spherical surface and to pivot about a first axis and a second axis thereby providing the at least two rotational degrees of freedom.

Link member for motion-enabled movie theatre chair

The present document describes an actuated chair for inducing motion with respect to the ground as a function of motion signals synchronized with a video output of a feature length movie. The chair comprises a seat base, and an actuating base for receiving the motion signals. The actuating base comprises three link members, namely a first link member, a second link member and a third link member. Each link member has one translational degree of freedom and two rotational degrees of freedom. The first link member and the second link member are attached to the seat base closer to the rear edge than the third link member. The actuating base further comprises three linear actuators for inducing motion to the seat base. The actuators are fixed to the frame and each actuator is respectively connected to the seat base using a respective one of the three link members.
