In a seat-rotating device that enables a seat to be rotated on a base member, a rattle-suppressing member operating in association with a lock member, which switches between the locked state in which rotation of an annular rotating member supporting a seat frame is prevented and release of the locked state, is in close contact with both a support member and the annular rotating member when the lock member is at the locked position, and a gap is created between the support member and the annular rotating member when the lock member attains the lock release position. Accordingly, it is possible to prevent the seat from rattling when it is in a stationary state and to facilitate rotation by releasing the rattle-preventing state when the seat is rotating.

A moving and locking device for a vehicle seat includes: a lower frame mounted on a bottom surface of a seat cushion; a plurality of wheels disposed underneath the lower frame in such a manner that the plurality of wheels roll on a floor panel; and a vacuum adsorption device disposed inside the lower frame and configured to be adsorbed on the floor panel by vacuum force. The vehicle seat is configured to be moved to the desired position through the rolling motion of the plurality of wheels, and configured to be locked at the desired position through vacuum adsorption of the vacuum adsorption device on the floor panel.

A rotational device (10) for a vehicle seat includes a base element (20) and a seat part support (30) which can be rotated about a rotational axis (S) with respect to the base element (20). At least three rolling bearings (61, 62, 63) are provided to rotationally support the seat part support (30).

The present disclosure provides a swivel stop comprising a rotating member, a first boss coupled to the rotating member and a second boss coupled to the rotating member, and a second plate having a first interference surface and a second interference surface. An interference between the first boss and the first interference surface and the second boss and the second interference surface tends to limit the rotation of the rotating member with respect to the second plate. The swivel stop may further comprise a rail wherein the second plate is configured to translate along the rail.

The present disclosure provides a brake assembly for aircraft cabin fixtures. A brake assembly includes a carriage, a lever having a ramp, a shaft, and a pivot, wherein the lever is coupled to the pivot, wherein the shaft is coupled to the lever, and wherein the carriage is configured to ride along the ramp. A brake assembly may comprise a spring in communication with the lever. The shaft may comprise a first end and a brake plate coupled at the first end. The ramp may comprise a slot. A brake assembly may comprise an actuation lever coupled to the carriage.

A seat pedestal includes an open base upon which a plate assembly is mounted for translational movement upon the base. The plate assembly includes a bottom plate, a seat mount for supporting a seat, and a bearing means between the bottom plate and the seat mount to permit the seat mount to rotate. One lock releasably secures the plate assembly in the driving position and another, which is self-actuating, releases the seat mount so that it can rotate freely when it is in the resting position. A stop carried by the seat mount defines a range in which the seat may be rotated. At least one pair of interlocking members couples the seat mount with the bottom plate to transfer lateral loads born by the seat to the base. The bottom plate, the bearing means, and the seat mount have concentric openings through which wires may pass for accessories such as power/heated seats, headrests, and computer screens and related accoutrements.

A rotating device for a vehicle interior item is provided with latching means that is provided on a side of a base member having a rotation support part, and engagement means that is provided on a side of a rotating member supporting a vehicle interior item and being rotatably supported by the rotation support part, and can be switched between a state in which the engagement means engages with the latching means so as to suppress detachment of the rotating member from the base member and a state in which the engagement with the latching means is released when the rotating member attains the rotatable state, wherein the latching means and the engagement means are disposed further outside than the rotating member in plan view at least when the rotating member is in the non-rotating state. Accordingly, it is possible to suppress an increase in the height while suppressing detachment when the vehicle interior item is not rotating.

The invention relates to a vehicle seat with a lower part for arrangement on a body part of a commercial vehicle and an upper part for storing a seat part, wherein the vehicle seat has a rotational adjustment device, by means of which at least parts of the upper part are rotatable relative to the lower part about an axis in the height direction of the vehicle seat, wherein the rotational adjustment device comprises an electric motor for rotating a rotary plate unit which is rigidly connected to the upper part and is mounted so as to rotate relative to the lower part about the axis, wherein a driveshaft of the electric motor which mechanically interacts with the rotary plate unit is arranged parallel to the width direction of the vehicle seat, wherein, viewed in each case in the height direction of the vehicle seat, an extension of the electric motor and an extension of the rotary plate unit are arranged to be at least partially overlapping.

A swivel device for vehicle seats may rotate a seat mounted inside a vehicle at 180° or more and firmly fix the seat at a normal position before and after rotation. The swivel device includes: a base plate provided with a plurality of first locking members; a swivel plate disposed on the base plate to be rotated by a second motor; a rotary force transmission mechanism mounted on an output shaft of the second motor and the swivel plate to transmit a rotary force of the second motor to the swivel plate; an elevating plate provided with a plurality of second locking members separably coupled to the plurality of first locking members and formed on a lower surface of the elevating plate; and a first motor mounted on an upper surface of the elevating plate to transmit a rotary force to the lead screw.

A seat assembly includes a swivel mechanism for providing rotation of the seat assembly in an automotive vehicle. The swivel mechanism includes a first plate assembly coupled to a second plate assembly at a rolling-element bearing to facilitate axial rotation of one of the first and second plate assemblies relative to the other of the first and second plate assemblies. A lock plate slidably disposed on the second plate assembly selectively engages a lock pin extending from the first plate assembly for movement between a locked position in which the swivel mechanism cannot rotate and an unlocked position in which the swivel mechanism can freely rotate. Actuation of the lock plate between the locked position and the unlocked position actuates movement of a wedge between a cinched position to stabilize the swivel mechanism and an uncinched position to allow unimpeded rotation of the swivel mechanism.
