Description

The invention relates to a seat with a seat support for receiving and supporting a seat plate having at least a rear portion and a front portion, wherein the rear portion, which serves to receive the seat legs (os ischii) is located lower than the front portion, wherein the seat support supports the rear area.

State of the art

From the DE 10 2006 050 394 A1 is known a seat with a seat support and a seat plate arranged thereon, which has a planar shape. The entire seat is surrounded by a foam shell, except for the central lower area. This sheath is formed in the upper seating area as a thicker, upwardly curved seat cushion and also extends below the underside as a relatively thinner layer on the seat support.

The seat support is arranged on a height-adjustable column, which is inclined at an angle to the front and is articulated in a bearing within a foot part. The foot section has an opening at the top, within which the column can move in all directions. underside rubber feet are arranged on the foot part to prevent slippage of the foot part on a smooth surface.

In the construction described, it turned out in the everyday application as disadvantageous that the design of the seat is uncomfortably hard acting on the seat occupant. Consequently, this constantly changes its seating position. As a result, the user does not feel comfortable on such a seat and exchanges it for a conventional chair or armchair, without a seat construction which avoids the physiologically adverse effects of conventional seats.

Therefore, the invention has for its object to provide a seat which avoids the physiological disadvantages of ordinary seats, but at the same time ensures a comfortable, the ischial tuberos gentle sitting.

The object is achieved by a seat with the features of claim 1.

The seat according to the invention comprises a seat support for receiving and supporting a seat plate having at least a rear portion and a front portion, wherein the rear portion, which serves to receive the seat legs (os ischii), is arranged lower than the front portion, wherein the seat support supports the rearward area, and wherein the front portion of the seat panel is compliantly designed as a flexible zone free of direct supports.

By means of this embodiment, an optimized seat is created, which avoids the disadvantages mentioned above. The formation of two areas of different heights makes it easier for the seat occupant by means of his ischial tuberosities to easily change the sitting position.

To improve the leg blood flow, it is favorable to form a transition region with a substantially continuous course between the regions and a flexible zone on the seat plate in the front region. Thus, pain of an impressing in the leg seat edge can be avoided become.

Advantageously, the flexible zone is designed as a cantilever. This allows a simple, inexpensive but also safe construction, which allows movement of the front area.

To prevent seat damage, it is beneficial to limit the deflection of the flexible zone or the front part. For this purpose, at least one support strut may be formed on the seat plate or on the seat support substantially between the transition region and the flexible zone. In an advantageous embodiment of the support strut on the seat plate or on the seat support is configured so constructive that the seat plate or the seat support can be easily manufactured by means of injection molding.

Advantageously, an elastic material is arranged between the at least one support strut and the flexible zone. This not only relieves the support strut, but also serves as a kind of damping means to limit the movement, or to prevent a rewinding of the flexible zone to its rest position.

Thus, the forces acting on the support strut forces can be derived, it is convenient to support the strut on a seat panel and / or on the seat support. In this way, the construction is able to divert the forces introduced to a base on which the seat can be placed.

To increase the comfort of the flexible zone, it is advantageous if this has radially arranged lamellar arms, which are increasingly softer from the inside to the outside radially. In this way, at the periphery of the seat in the front area different sections can be created with various compression paths.

For the mechanical stability of the arrangement consisting of support strut and flexible zone, it is advantageous if the two substantially together form a V, which is open towards the edge region. Thus, a flexible arrangement created, which fulfills its task of jibing or forwarding, without being destroyed by larger forces.

To increase the mechanical strength, it is also advantageous if the seat plate, the seat support and the seat panel are connected to each other in the rear area. Through the connection, the acting forces can be passed from one area to the other, which distributes the total force acting on all parts. Consequently, the safety of the individual parts against breakage can be increased.

In a preferred embodiment, the seat panel has a handle, wherein the seat panel rests substantially form-fitting manner on the seat carrier, and the seat carrier has on the underside a hub with a cone receiver for a base frame. The positive engagement between seat support and seat cover again increases the mechanical stability. The handle is used for easy change of position of the seat or a seat assembly.

In a further advantageous embodiment, the seat can be arranged on a particular designed as a pillar base and a foot, wherein in the base frame and / or between the base and foot and / or in the foot part of an arrangement, in particular a pendulum joint is formed, the one Pendulum movement of the seated person allows. A seat with at least two areas of different heights is particularly suitable for an arrangement which is suitable for pendulum movements, since in positioning the ischial tuberosities in the region of a lower rear area in a simple manner pendulum movements can be performed. This is due to the intervention of Sitzhöcker in the lower area. This creates a secure contact between the ischial tuberosities and the seat.

Furthermore, it is advantageous if the pendulum joint on the upper side has a circular flange, a conical bearing and an arranged in the bottom region substantially rectangular plate with a recess, wherein between the flange and the plate, a rubber element is arranged. The pendulum joint can in this case be tiltable in all directions with respect to a vertical axis. The inclinability is made possible by the rubber element, wherein the rubber element can also be designed to limit the pendulum width of the column and the seat.

Furthermore, it is advantageous if the base frame designed as a pillar extends through the recess. This allows a support of the column on the ground.

It is advantageous if the lower frame formed as a column is a gas spring. Thus, a height adjustment of the seat can be achieved in a simple manner.

Preferably, the recess with clearance form-fitting to the column. Thus, a restriction of the pendulum can be made using the recess.

This restriction can also be formed only for certain directions by the recess is formed as a slot to give the pendulum motion in one direction.

For seat arrangements whose pendulum width is set too far, it is possible to arrange on the plate arranged in the bottom area a limiting element which limits the pendulum width of the column.

Advantageously, the limiting element has a recess with play positively to the column. Also, it may be provided with a recess formed as a slot to release the pendulum motion in one direction.

In a further advantageous embodiment, the foot part on the underside of the edge on a rubber strip. Thus, when exceeding the pendulum range and the associated tilting of the foot injury can be prevented because it is no longer possible for the foot, in certain positions slipping away, as is known in the art.

Due to the simple movement of the seat by means of the areas of different heights, it is advantageous if a device which restricts and / or impedes a pendulum movement of the seated person is formed on the foot part. In this way, a scare of seat occupants who do not expect a movement of a pendulum seat, can be prevented.

It is advantageous if the device is formed on the foot as a plate. Thus, the movement of the column of a swinging underframe can be limited in a simple way.

In an advantageous embodiment of the device, this has a recess in which the column, in particular as a gas spring, can be used.

To restrict the pendulum movement of the column, it is advantageous if the recess is formed positively to the column. In this way, the pendulum movement can be easily limited by designing the recess. Furthermore, this also makes it possible to limit already existing pendulum seat arrangements in their pendulum behavior.

For example, to allow a pendulum motion in a particular direction, it is convenient to form the recess as a slot. In this way, a pendulum movement can be released in a direction in which no unexpected tilting of the seat is to be expected.

To increase the operational capability of a pendulum seat this is conveniently provided on the underside of the edge of the foot part with a rubber strip.

In an advantageous embodiment of the seat plate, it is advantageous if it has at least one pad. The at least one pad can be arranged below and / or above the seat plate. Thus, on the one hand, a uniform shape for the seat can be created and, on the other hand, the seat can be pleasantly padded for the user.

In an advantageous embodiment, the pad is formed of a flexible foam and / or an integral foam. Due to the fact that both types of foam have different degrees of hardness, the user's desire for the different areas of the seat can be accommodated.

Advantageous embodiments and features will become apparent from the following description of exemplary embodiments, which are explained in conjunction with the drawings.

Detailed description of the embodiments illustrated in the figures

In Fig. 1a a seat 1 is shown in a sectional side view. The seat 1 consists for the most part of a cushion formed with foam 11,12, which is arranged both below and above a seat plate 3. The pads are with the seat plate 3 via fastening means such. As adhesives connected and lie flush against the seat plate 3.

The seat plate 3 has a curved course with two areas of different heights, in which a rear area 4, which serves to receive the seat legs, is arranged lower than a front area 5 for supporting the legs.

The formation of two areas of different heights makes it easier for the seat occupant by means of his ischial tuberosities to change the sitting position in a simple manner. This is easily achieved because the seat leg bumps are in a deep area such as the rear area 4 engaged by the shape of the seat with the different high areas and thus can interact. Consequently, it is ensured that the seat can follow small changes in the user pool. Characterized in that the front portion of the seat plate is designed to be flexible without direct supports, a resilience of the seat plate can be achieved in this area. This guarantees optimal blood supply to the legs in every sitting position so that falling asleep can be avoided.

The seat plate 3 is received by a seat support 2 and supported mechanically by means of support struts 7 ', 7 "in the transition area 6 and in the rear area., On the other hand, the front area 5 is designed to be free of direct supports as flexible zone 9 so that it can perform movements.

Due to the design of the flexible zone 9 as a cantilever, the one-sided deflectability of the front region 5 is supported on the edge region 10, wherein the deflection of the flexible zone or the front region is limited by a support strut 7. This is arranged substantially below the front region 5 of the seat plate 3 between the transition region 6 and the flexible zone 9. In this case, the support strut 7 extends obliquely forward in the direction of the edge region 10. Further, it is designed in one piece with the seat plate 3, whereby the seat plate 3 together with support strut 7 by means of injection molding can be made.

Although such a support strut 7 limits on the one hand the mobility of the front portion 4, on the other hand, a folding away is avoided, whereby the size of the seat is maintained and thus remains usable. By forming the support strut on the plate 3 or the carrier 2 assembly work can be saved and the assembly can be facilitated.

Between the support strut 7 and the front region 5 of the seat plate 3, an integral foam is arranged, which carries the spring movements of the flexible zone 9 on the support strut 7. The support strut 7 extends the forces from the spring movement on the seat panel 22, which limits the deflection of the strut or serves as a stop. The stop restricts the freedom of movement of the support strut 7 so that the spring travel can be adjusted via its positioning.

The support strut 7 and the flexible zone 9 substantially together form a V which is open towards the edge region 10. Thus, the support strut is able to rebound to not break off in the event of a seesaw of the seat occupant. The support strut 7 "further supports the strut 7 in order to further limit its deflectability and to increase the stability of the overall arrangement.

Centered below the seat 1, a hub 27 is arranged on the seat support 2 with a cone holder for a base. Within the hub 27 is a cone bushing 20, which provides the positive and frictional contact with a column 13 (not shown).

Below the cone bush 20, a conical cover 21 is arranged, the fastening screws, which connect the seat support 2 with the seat panel 22, covers.

In the transition 6 and in the rear area 4, the seat panel 22 is substantially positively against the seat support 2, wherein the seat support 2 via the support struts 7 ', 7 "is in contact with the seat plate 3.

The seat panel 22 has a handle 19, by means of which the seat can be easily transported to another location. Here, the handle 19 and the seat panel is connected not only as described above with the seat support 2, but also with the seat plate 3. Thus, all parts of the seat 1 in the rear region 4 are connected to each other. The forces acting on the seat by the handle or the user's weight can be dissipated to the bottom-mounted hub 27 with cone seating disposed on the seat support 2, which relays the forces to the underframe.

Fig. 1b shows the front area 5 and the flexible zone 9 in an upper view. Here, the zone 9 has radially arranged lamellar arms 8, which are increasingly softer from the inside to the outside. In the example shown, the lamellar arms are made the same width, but also different shapes and sizes are possible. By means of the lamellae 8 is - even with weight shift from one foot to another - an impressions of the seat plate edge in the leg prevented. This results in movements on the seat to a comfortable seating feeling that invites you to move while sitting. Furthermore, circulatory disorders of the legs in the various seating positions are safely avoided. In the case of attachment of the seat on a height-adjustable base this training is particularly for high seating positions of advantage, since a depression of the front portion is avoided with its edge region in the thigh bottom of the user.

Further shows Fig. 1b an alternative embodiment of the flexible zone 9 in the front region 5, wherein stabilizing elements are arranged on the underside of the lamellae. The stabilizing elements consist of individual ribs spaced by V-shaped cuts. In a deflection indicated by the arrow, the width of the incisions between the ribs is reduced until the opposite surfaces abut each other, so that further deflection of the lamella arms is prevented.

Alternatively, it is also possible that the incisions are formed in different shapes and with different opening widths, wherein different compliances can be realized and wherein an inverted V-shaped configuration is preferred.

Fig. 2 shows a sectional view from the front through the seat 1, wherein the trigger mechanism is shown for adjusting the seat height.

The triggering mechanism has a left button 23 and a right button 24, which act on a gas spring (not shown) via levers 23a, 24a to determine their height deflection. The gas spring is disposed in the cone bush 20 and thus firmly connected to the seat support 2 and to the hub.

The trigger mechanism is in this case arranged in given recesses within the seat support 2, wherein the individual components are arranged lying freely in their recesses.

Further shows Fig. 2 in that support webs 25 are inserted between seat plate 3 and seat cover 22.

Fig. 3 shows an exploded view of the seat, wherein the pad 11 is fixed by means of adhesive to the seat plate 3. The seat plate 3 is arranged after insertion of the lever 23a and 24a and the buttons 23 and 24 for triggering the gas spring on the seat support 2 and fixed by means of fastening screws. Subsequently, the structure consisting of pad 11, seat plate 3, seat support 2 with the associated mechanism (button and lever), connected to the seat panel 22 via screws. The connecting screws, which are attached to the seat cover, are concealed in the region of the cone bushing 20 from the conical cover 21. In this case, the conical diaphragm 21 has four lugs, which can snap into corresponding recesses on the seat panel.

Fig. 4 shows the assembled seat, consisting of the in Fig. 3 explained components from different perspectives, such as a front view A, a bottom view D and a top view C.

In Fig. 5 is an exploded view of the seat on a particular trained as a pillar base 13 and a foot part 14, wherein in the foot part 14, a pendulum joint 15 is formed, which allows a pendulum motion of a seated person.

The pillar 13 extends in the central region through the foot part 14 to a substantially rectangular plate 26. The plate 26 is provided with a recess 17 through which the pillar 13 extends. Here, the recess 17 is formed with play form fit to the column 13, so that the pendulum range or the pendulum of the column 13 is limited or completely limited.

Furthermore, a rubber strip 18 is on the underside of the edge to protect against slipping of the foot part 14 on a smooth surface.

In Fig. 6 the recess 17 is formed as a slot to release the pendulum motion in one direction. In this case, this recess is also designed with a form-fitting manner with play in order to lock the unwanted pendulum directions. Also possible is an attachment of a plate arranged in the bottom region on a pendulum in all directions seat as a limiting element, so that the pendulum width of the column 13 is limited. This recess may have a game form-fitting to the column. Furthermore, a recess as a slot is also possible here to release the pendulum motion in one direction.

The invention is not limited in its execution to the above-mentioned preferred embodiments. Rather, a number of variants is conceivable, which makes use of the solutions shown even in fundamentally different versions. For example, it is within the scope of the described invention to alter the shape of the plate or to supply the shape profile of seat support 2, seat plate 3 and / or seat cover 22 a different course.
