  • Patent number: 7387339
    Abstract: The invention relates to furniture, in particular to sitting devices and can be used as a work chair or therapeutic furniture. The aim of said invention is to develop a sitting device which would make it possible to efficiently relieve the backbone in a sitting posture taking into consideration individual morphological and functional asymmetries, thereby normalizing the work of other organs and systems of an organism, first and foremost the organs of the small pelvis, optimizing the “turtuosity” of the backbone associated with constitutional and geophysical factors.

  • Patent number: 7350865
    Abstract: A chair that has movable thigh levers to permit a shifting of body weight when seated and thereby relieve spinal discomfort and pressure points experienced when seated for long periods. A lever support rocker is provided to coordinate movement of the thigh levers. Downward pressure exerted by a user's thigh to lower a first thigh activated lever causes a rocking movement of the lever support rocker which results in an upwardly movement of a second thigh activated lever.

  • Patent number: 7350863
    Abstract: Work chair, comprising a seat, supported in a height-adjustable manner by a column on a foot, and an adjustable backrest, the seat, at least in part, having a substantially horizontal position, and the backrest promoting an upright position of the user's back, characterized in that the column (3) is composed of three parts (4, 5, 6) and as a result provides a two-stage adjustability for the seat height, in that the seat is divided into two parts (7, 8), in such a manner that a rear section (7) is fixed and always retains the substantially horizontal position, while a front section (8) is hinged with respect to the rear section, and in that the front section (8) is secured to the column (3) in a hinged manner (11) by a rod (9) secured to it in a hinged manner (10). The chair can be dimensioned in such a way that it allows an ergonomic working position to be adopted by virtually all users, irrespective of their corporal size, with the possibility of increasing the size of the workstation.

  • Patent number: 7341309
    Abstract: A seat bottom assembly for a passenger seat, includes a flexible component; and a structural support member underlying the flexible component. The support member is selectively moveable between a first, forward position in which the seat bottom has a nominal length in a longitudinal direction, and a second, rearward position in which a portion of the flexible component bends downward over the structural component such that at least a portion of the seat bottom assembly has an effective length less than the nominal length. The left and right sides of the seat bottom assembly may be independently varied in length.

  • Patent number: 7341233
    Abstract: In a chair having a base, a seat defining a fore-to-aft longitudinal axis, a seat back and a tilt control mechanism, a horizontal adjustment mechanism is provided for allowing fore-to-aft movement of the seat relative to the seat back. The mechanism includes a first plate adapted to be coupled to the seat; a second plate adapted to be coupled either directly to the base or to the tilt control mechanism, the second plate being slidably coupled to the first plate such that the two plates can move relative to one another along the longitudinal axis of the seat; an intermediate element positioned between the first and second plates for facilitating relative sliding movement therebetween, and a handle positioned between first and second plates that selectively positions the first plate in relation to the second plate.

  • Patent number: 7090303
    Abstract: A rehabilitation training and exercise chair where the user can sit comfortably for long periods of time is provided. The chair is comprised of a base having wheels and is coupled to a shaft on one end. The shaft is coupled to a seat on its top end. The seat has an adjustable inclination so the correct ergonomics may be realized for the pelvis and lower spine. A front support bar with an adjustable length is connected to the seat and can be pivoted back or forward. The front support bar has a cushioned front support which rests against a user's abdomen. Furthermore, abductor and adductor extensions are attached to the seat, and foot extensions attached to the base for isometric exercises.

  • Patent number: 6910736
    Abstract: The invention relates to a seat or seat back comprising of seat elements which are arranged to resiliently move with respect to each other and arranged to move with respect to a central axis, running centrally through the seat or seat back parallel to the spine of the occupant in a normally seated position, the first and second seat elements moving in opposite directions on either side of the central axis. The seat elements may rotate and are subject to a restoring force urging them to return them to their rest positions such that the user is able to move in a twisting position and the seat back or seat will also twist with the twisting movement of the user and provide support in the newly adopted position of the user. The seat elements could be formed from a single piece of resilient material.
