An aligned displacement of the upper rails relative to the lower rails displaces the seat shell in a straight line. A displacement of the first upper rail relative to the second upper rail rotates the seat shell about a vertical axis. An initial position is stored. The seat shell is moved in a straight line out of the initial position into a starting position. From the starting position the seat shell is rotated by a first angle into an intermediate position. The seat shell is moved in a straight line in the direction of travel into a first central position. The seat shell is rotated by a second angle into an end position. | 05-22-2014 |
20150035334 | VEHICLE SEAT - A vehicle seat having a seat shell, includes a first upper rail, which is arranged on the tunnel side and is movably guided in a first lower rail, and a second upper rail, which is arranged on the sill side and is movably guided in a second lower rail. The first upper rail can be displaced relative to the second upper rail, and due to that displacement the seat shell carries out a rotation about a vertically extending pivot axis. A main memory device is provided on the second upper rail, and at least one spring unit is provided, which acts upon the first upper rail relative to the second upper rail in the longitudinal direction. | 02-05-2015 |

20090140564 | SWIVEL CHAIR - A swivel chair includes a seat unit and a base unit. The seat unit includes a downwardly extending post. The base unit includes: a base member; a sleeve member that extends upwardly from the base member, that surrounds the post of the seat unit, and that has a top end portion; a bearing that is disposed fixedly in the sleeve member and that is sleeved on the post so as to couple rotatably the post to the sleeve member; a first positioning ring that is fixed in the top end portion of the sleeve member, that surrounds the post, and that forms an annular clearance with the post; and a second positioning ring that is sleeved fixedly on the post, that extends into the first positioning ring, and that is rotatable relative to the first positioning ring. | 06-04-2009 |
20100264711 | SWIVEL AND RECLINING CHAIR - A swivel and reclining chair has a base support, a base bowl mounted on the base support, and a seating bowl slidably disposed in and over the base bowl. A plurality of friction reduction features are disposed on the inside surface of the base bowl. The outer surface of the seating bowl is spherical in shape and rests on the friction reduction features. The seating bowl is larger in area than the base bowl, and can freely slide in two dimensions as well as rotate in a spherical surface. Optionally, a guard ring is disposed outside of the base bowl and is attached to the base bowl at their rims. | 10-21-2010 |
20110163586 | PORTABLE FOLDING CHAIR - A swivel chair including a swivel-mounting assembly having a lower plate, and an upper plate, and bearings for rotatably mounting the upper plate to the lower plate. The lower plate and the upper plate defining an annular gap therebetween cooperating with the interior of the swivel-mounting assembly. The improvement includes an annular gasket having a first portion that receives the bearings is positioned in-between the plates. The annular gasket further having a second portion depending from the first. The second portion includes upper and lower sections extending from the first portion and have an inside facing section being in partial surface-to-surface contact with the lower and upper plates. Thus, the annular gasket prevents foreign particles from entering into the interior of the swivel-mounting assembly. | 07-07-2011 |
20140217796 | UTILITY VEHICLE SEAT WITH A ROTATION ADJUSTMENT DEVICE OVERLOAD PROTECTION UNIT - The invention relates to a utility vehicle seat with a seat part, with a backrest part and with a seat substructure for arrangement on a bodywork part of a utility vehicle. The seat substructure includes a rotation adjustment device for rotating at least the seat part with respect to the bodywork part with a ball bearing unit, and with a rotating shell part which is rotatable with respect to a stationary shell part. The utility vehicle seat further includes a rotation adjustment device overload protection unit with support elements by means of which the rotating shell part and the stationary shell part are additionally capable of being supported with respect to each other when the carrying capacity of one of the circular ball tracks reaches or exceeds a critical deformation value. | 08-07-2014 |
