Definitions
- the invention relates to a seat with a central region and an adjoining outward adjoining edge region.
- the ischial tuberosities (tuber ischiadicum) usually pressed by a too soft seat in a hollow inward and pushed apart the pelvic blades as biomechanical countermovement, creating a slight kyphosis in the lumbar spine. This undesirable effect is called an “outflair”.
- the ischial tuberosities should be pushed outward from the surface of the seat to expose the intervertebral discs and prevent kyphosis, thus moving the pelvic blades inwards, thereby maintaining the physiologically correct lordosis position of the spine. This is called "inflair”.
- a seat body which has an increased number of transversely extending slots in the front seating area such that this forward area has greater flexibility than the remaining areas of the seat.
- the rigidity is increased by transverse to the seating direction arranged reinforcing ribs.
- each extending in the seat direction stabilizing elements are provided on the lateral edges of the seat plate, which consist of successively arranged in series blocks. Below the blocks, a support surface is formed, on which the blocks come to rest on bending down the seat.
- the blocks have a wedge-shaped gap towards the respective neighboring block, which closes when bending the free end of the seat plate down.
- this design does not produce the required softness while maintaining sufficient stability.
- the invention is therefore based on the object to provide a seat construction which avoids the physiologically adverse effects of conventional seats.
- the seat according to the invention with a central region and an adjoining edge region to the outside is characterized by a suspension, which has an increasing from the central region to the edge region towards yielding.
- a suspension which has an increasing from the central region to the edge region towards yielding.
- the seat has a suspension that provides a stronger central area relative to the edge region and thus prevents inward compression of the ischial tuberosities and impairment of the blood supply to the legs.
- Radially arranged spring arms extend from the fixed central region of the spring in the direction of the edge region, of which at least the forwardly pointing spring arms are formed increasingly softer radially outward. In this way, a stronger against the surrounding portions of the seat central area is made possible. Due to the softer design of the spring arms, the seat can give way, whereby any unfavorable pressure against the underside of the thighs is avoided.
- the front edge of the seat adapts to the body shape and the movement of the underside of the thighs.
- the spring arms are formed as an array of leaf springs, wherein the inwardly directed spring arms may be formed longer and wider than, for example, the laterally arranged. In order to achieve the increasing compliance to the edge region, preferably a plurality of leaf springs of different lengths can be arranged one above the other and thereby become shorter from top to bottom.
- the thickness of the individual spring arms can be designed individually and independently.
- the shape of the spring arms is also variable in any Welse, as long as the technical function is maintained.
- the suspension may be formed of a combination of elastomeric foam material of different nature. It is also possible that the foam material is supported by a spiral spring arrangement.
- the seat has at least one foam layer made of a translucent material, wherein light may shine through the foam in the region of thinner layers, the foam is not made transparent in the region of thicker layers. This conveys to the viewer that it is a seat with a compliant edge area.
- the foam layer improves the seating comfort.
- a comfort zone made of soft integral foam arranged in the edge region, or the seat may be completely foamed by soft integral foam substantially.
- the surface of the soft integral foam is preferably flocked by flocking.
- the comfort zone gives the occupant a pleasant sitting feeling in the edge area, so that the seat is indeed felt, but at no point uncomfortably presses against the thighs.
- the suspension is designed as a plate spring with radially outwardly decreasing spring force, whereby the advantages described above can also be achieved.
- the disc springs may also be slotted.
- a stabilizing element in a preferred embodiment, can be arranged as a rib arrangement with properties becoming stiffer as the bending increases. It is favorable that the rib arrangement can have at least one web, which is provided on the underside with several cuts.
- the incisions may be formed in various shapes and with different opening widths, with an inverted V-shaped configuration being preferred. Also, the opening width of the incisions may be made variable to the edge region, in order to adjust and limit the yielding movement in this way.
- the rib arrangement may also consist of a kind of dovetail engagement, the engagement becoming deeper as the deflection increases, until the corresponding mating surfaces abut one another and further deflection is prevented.
- a dovetail design of the rib members in both vertical and horizontal orientations causes central engagement of the rib sections and prevents unwanted lateral deflections of the spring arms.
- the stabilization is effected by a limiting element in the form of a loose band, which is arranged laterally between the spring arms or under the diaphragm spring.
- a limiting element in the form of a loose band, which is arranged laterally between the spring arms or under the diaphragm spring.
- the seat has a convexly curved seat support, which may be harder in the middle and softer towards the edge. This supports the more stable formation of the central area in relation to the edge area.
- the seat is arranged in a seating furniture construction, which has a base, preferably designed as a pillar or gas spring, and a foot part, wherein preferably the foot part has a joint which a pendulum movement of the seated person together with the seat and allows the undercarriage.
- the arrangement of the joint is also possible on different areas of the undercarriage. The higher the pivot point of the joint and thus located closer to the buttocks of the seated, the less favorable the lumbar spine is loaded. Therefore, in the preferred embodiment, the hinge is disposed on the foot part. With the base and seat tilting, the occupant needs to use at least one support leg to maintain balance. In this way, the lumbar spine stays straight in line with the base.
- a seat plate for receiving the seat can be arranged on the base frame.
- the seat plate may be formed with a receptacle for mounting on a component belonging to the substructure, in particular a gas spring.
- the spring arms can be injected in this embodiment, for example, in the foam and do not necessarily have to be in contact with the seat plate.
- the seat is individually adjustable in height.
- the height adjustment for example in a particularly long gas spring, the use is advantageously also possible as a standing seat.
- the subframe is designed as a telescopic column, which can be equipped with a lock.
- the height is also adaptable to different sized people.
- the column may comprise a spring, whereby the seat is resiliently received on the column. This can be advantageous, since in this way vertical rocking movements of the seated person are also made possible and the vertebral column is vertically loaded differently and consequently the surrounding muscles are trained.
- the spring on the base can also be used in all other versions, as far as this is technically possible.
- the base frame can be arranged on the foot part in a storage and with respect to a vertical axis in all directions can be tilted. In every possible tilt position, the column can be locked.
- the inclination is at least as far feasible that at any height of the seat, i. each possible length adjustment of the column, between the foremost point of the seat and the foremost point of the foot part, a vertical line is adjustable. This is for a sitting independent of the seat in equilibrium sitting, without falling forward, backward or in a lateral direction, advantageous.
- the joint may be formed in the foot as a pendulum joint with at least one rubber element to limit the pendulum width of the column and the seat.
- the rubber element can be biased by a mechanism, the mechanism offers different adjustment options of the bias. In this way, the different preferences with respect to the pendulum range or ease of commuting of the seated be taken into account. Also in this way the supporting force is influenced by the foot of the person sitting, i. with a large bias of the rubber element only a small or no support force is necessary.
- the foot part may comprise means for determining the inclination of the column and means for adjusting the bias, wherein the means are preferably formed by a self-adjusting screw with a handwheel.
- the occupant can advantageously make adjustments in a simple manner in accordance with his or her individual preferred and ergonomically correct setting with regard to the height, inclination and possible pendulum width of the seat.

If the sitter were sitting too far forward with the ischial tuberosities, he would slip over the edge area or would have to support himself much more with his feet.
- the front edge area thus forms a comfort zone, which is when sitting at the level of the thigh, but does not press against the underside of the thighs.
- the seat can be positioned by adjusting the inclination of the undercarriage so that the front edge of the seat can form a vertical line with the front edge of the foot part at any height adjustment of the undercarriage. In this way, one sits in equilibrium with slight support with the feet, whereby the physiological lordosis position of the spine is maintained.
- the underframe is mounted in the foot part such that the inclination is adjustable via an adjustment of the tilting device. Due to an articulated mounting by means of a rubber element and a predetermined pendulum width in all directions is also possible, which is limited by a stop in all directions.
