The removable seats system comprises a number of vertically movable platforms that have a small horizontal gap between each two successive platforms, with the edges of the platforms being curved along the gap. Seat members are each associated to a corresponding platform and each comprises a row of seats and a seat supporting structure that carries the seat members. Each seat member is movable relative to the corresponding platform between an operative position in which the row of seats is located above the corresponding platform for allowing persons to sit on the row of seats, and a stored position in which the row of seats is located under the platform. The seat supporting structure comprises at least three discrete, spaced-apart seat support arms that, in the operative position of the seat member, extend through the gap between two successive platforms, with the seat support arms being disposed in non-linear relationship along the seat member.
The linear actuator comprises elongated first and second bands that cooperate to form an extractable and retractable column. Rotatable first and second band guide members respectively guide turns of the first and second bands into intertwined engagement. A power actuator causes rotation of the first and second band guide members such that the extractable and retractable column may be extracted or retracted. A base carries the power actuator, the first and second bands and the first and second band guide members. An anti-rotation mechanism comprises a first anti-rotation member attached to the base and a complementary second anti-rotation member attached to at least one of the first and second bands, with the first and second anti-rotation members engaging one another in the column to prevent rotation of the column relative to the base. The engagement of the first and second anti-rotation members is non-punctual about a periphery of the column.
F16H 25/12 - Gearings comprising primarily only cams, cam-followers and screw-and-nut mechanisms for interconverting rotary motion and reciprocating motion with reciprocation along the axis of rotation, e.g. gearings with helical grooves and automatic reversal
The linear actuator comprises upper and lower frame portions vertically movable relative to one another along a central axis, and first and second bands that intertwine to form an extractable and retractable column. The second band forms the wall of the vertical column, and it is the second band that is supported by a rotor that is rotatably carried by the lower frame portion, to reduce the mechanical stress on the first band.

The removable seats system comprises first and second platform members comprising respective first and second floor panels carried by respective first and second platform support and displacement mechanisms that support the first and second floor panels spacedly over ground and that allow selective relative vertical displacement of the first and second floor panels in horizontally adjacent respective first and second spaces. A seat member comprises a row of seats and a seat supporting structure supporting the row of seats. A transversal seat displacement mechanism allows the seat member to be displaced transversely towards and away from the first space. The seat member is movable between an operative position in which the seat supporting structure is carried by the first platform member and in which the row of seats is located above the first floor panel, and a concealed position in which the seat supporting structure is carried by the first platform member and in which the row of seats is located under the first floor panel. Displacing the seat member between its operative and concealed positions comprises transversally displacing the seat member with the transversal seat displacement mechanism from the first space towards the second space, engaging the seat member with the second platform member, vertically relatively displacing the first and second platform members such that the seat member is vertically displaced with respect to the first platform member, transversely displacing the seat member towards the first space, and releasing the seat member from the second platform member.

MULTIPURPOSE ROOM, CARRIAGE FOR USE IN A MULTIPURPOSE ROOM AND METHOD OF INSTALLING AND REMOVING SEAT MEMBERS ON AND FROM A FLOOR OF A MULTIPURPOSE ROOM
The multipurpose room comprises a floor, a number of seat members and a carriage capable of carrying the seat members and capable of displacement along the floor between a storage area and a multipurpose area. A guide element is mounted to the carriage. Guide members are provided in the multipurpose room, distinct from the carriage guide element and capable of cooperating with the carriage guide element for guiding the carriage in its movement at least in the multipurpose area. The seat members can be unloaded from the carriage to be installed on the floor in the multipurpose area and removed from the floor to be loaded on the carriage.
The removable seats system has a first vertically movable platform defining opposite upper and lower sides, a seat member comprising at least one seat and first and second complementary male-female engagement members respectively provided on the first platform and on the seat member.

The linear actuator (10) comprises an elongated first band (26) wound in helical form about a central axis (11) and an elongated second flat band (36) wound on itself with its turns substantially transversely parallel to the central axis (11). The first (26) and second (36) bands are capable of taking retracted and expanded positions whereby in the retracted position the bands (26, 36) are spaced from each other. First fastening means (34) and second fastening means (40, 42) are longitudinally disposed along the first (26) and second (36) bands respectively, whereby the second fastening means (40, 42) is capable of cooperating with the first fastening means (34) to releasably interlock the first (26) and second (36) bands. Spacer means space the turns of the first band (26). Drive means cause rotation of the first (26) and second (36) bands and the spacer means about the central axis (11). Guide means (37) guide the turns of the second band (36) towards the turns of the first band (26) to interlock the first (34) and second (40, 42) fastening means.
The linear actuator comprises an elongated first band wound in helical form about a central axis and capable of taking a retracted position and an extended position with its turns spaced from one another in the direction of the central axis, and first fasteners carried by the first band and longitudinally disposed therealong. The linear actuator also comprises an elongated second substantially flat band wound on itself, with its turns substantially transversely parallel to the central axis, and capable of taking a retracted, spiral position with its turns nested within one another and an extended position with its turns forming a helix around the central axis and generally equally radially spaced therefrom to form a telescopic column, the first and second bands, when in retracted position, in respective locations so as to clear each other. Second fasteners are carried by the second band and longitudinally disposed therealong, the second fasteners capable of cooperating with the first fasteners to releasably interlock the first and second bands. A spacer successively spaces the turns of the first band. A powered drive causes relative rotation on one hand of the first and second bands and on the other hand of the spacer about the central axis. Guide means guide the turns of the second band towards the turns of the first band to releasably interlock the first and second fasteners. A retaining member retains the first and second fasteners in interlocked fashion in the telescopic column.
A removable seats system includes a number of vertically movable platforms supported by a platform support and displacement device which engages the platforms and which positions the platforms in a horizontally successively spaced configuration defining a gap between each two successive platforms having selective independent vertical displacement of the platforms. The removable seats system further includes a number of seat elements each associated with a corresponding platform and each including: a row of seats including at least one seat; and a seat supporting structure carried by a platform and supporting the row of seats. Each one of the seat members is movable relative to its corresponding platform between an operative position in which the row of seats is located above its corresponding platform, and a concealed position in which the row of seats is located under a platform.
