Abstract
The mounting for a seat (3) is suitable, in particular, for a chair, but also for stools, individual seats (3) on a bench or fixed seats (3). The mounting makes it possible for the seat (3) to swing resiliently in all directions or in defined directions, in accordance with changes in the user's posture. The seat (3) rests on an underframe on which a spring element (4) is arranged, said spring element being restrained in a casing (5,6) and being capable of moving elastically, in a horizontal plane, therein. The casing (5,6) is connected to the seat (3) or forms a part thereof. The spring element (4) is preferably arranged at the top of an axially extensible push rod of a pneumatic spring (2). The outer sleeve (43) of the spring element (4) is a rubber body, while the axial through-passage (45) of the spring element (4) has a preferably metallic core (44) around it. The specific advantages of the mounting result in improved seating comfort.
Description
- The present invention relates to a mounting for a seat, in particular a chair, but is also suitable for stools, individual seats on a bench or fixed seats in vehicles or, for example, in stadiums or parks. The invention specifically concerns a seat mounting which makes it possible for the seat to swing resiliently in all directions or in defined directions. Such seats follow the user's posture and, beyond the resilient mounting of the seat cushion, give the seat user a freer feeling of swinging action.
- Mountings for seats are known in a wide range of designs. For work chairs, in particular, the capacity for height adjustment and the resilient mounting of the backrest are standard nowadays (see, for example, WO 98/16140). Many chairs are equipped with a synchronizing mechanism, as a result of which a movement of the backrest is followed by a simultaneous, synchronous movement of the seat surface. The capacity for height adjustment is brought about mostly by a pneumatic spring, while, for the synchronizing mechanisms, use is made of helical springs, pneumatic springs, torsion rods or combinations thereof (e.g. U.S. Pat. No. 5,417,473;
EP 0 839 478 A1; WO 00/22961). WO 90/14031 discloses a mechanism in which the seat carrier is seated on a ball-and-socket joint, with the result that the seat can be rotated and inclined. The set rotary position and inclination can be arrested by means of a catch. In order to have resilient seat movement in the forward direction, use is also made of rubber bodies which are compressed between a fixed framework part and the moveable seat carrier as the load to which the front seat edge is subjected increases (see, for example, U.S. Pat. No. 3,863,982; U.S. Pat. No. 4,890,886). - The chair mechanisms which are relevant to the present invention make it possible for the seat to swing resiliently in all directions. Such chairs, stools and the like tend to move in the direction of the inclination or shift in the center of gravity of the user's body and extend the freedom of movement beyond the resilient mounting of the seat cushion, with the result that the seat user feels the swinging action. For this purpose, it has been practised for the central column of the seat to be divided horizontally and for a radially encircling rubber ring to be introduced (see CH 685 848; DE 43 01 734 A1) or for a planar rubber cushion to be arranged between the divided central column (see CH 678 388; U.S. Pat. No. 5,024,485). Either these designs barely provide the desired swinging effect or else the user has a certain feeling of instability and, in the case of deflection, immediately feels that it is harder to sense where the desired movement is going to stop.

FR 2 514 303 discloses, from the field of mechanical engineering, in particular of engine mounting, a vibration-absorbing arrangement in order to reduce the vibrations to which the framework is subjected. For this purpose, a damping element with a more or less insulating elastomer layer introduced therein is arranged between the vibration source and the framework side. Apart from the fact that this damping element, from a totally different field of expertise, has a quite different task—from mounting a seat—such a damping element is not suitable for mounting a swinging seat. - In view of the mountings for a seat with swinging freedom of movement not being fully effective up until now, the object of this invention is to propose such a mounting which is more effective and has an improved service life. It is also the aim here for it to be possible for the mounting to be efficiently mass-produced and instooled in different seats.
- The mounting for a seat which rests on an underframe has a spring element arranged on the underframe. The spring element is positioned in a casing and allows the casing to move elastically in the horizontal plane. The casing is connected to the seat or forms a part thereof.
- The following features constitute advantageous embodiments of the invention: the spring element is arranged at the top of an axial column of the underframe, preferably on an extensible, axially acting spring. The spring element is intended, in particular, for being arranged at the top of an axially extensible push rod of a pneumatic spring. The spring element has an elastic outer sleeve, e.g. a rubber body. The casing has a bottom, cup-like part in which the spring element is seated. The spring element and the casing have an axial through-passage. Alternatively, the casing, in which the spring element is seated, is a cup-like part which encases the spring element from above.
- The spring element comprises an inner, preferably metallic core and the elastic outer sleeve, which is arranged thereon. The core has an opening, preferably an axial through-passage, for accommodating the column. The radial, outer circumference of the outer sleeve of the spring element is preferably cylindrical or tapers conically in the upward direction or is essentially of cylindrical shape with a top and bottom reduction in diameter. The core is fixed to the outer sleeve.
- In a variant of the mounting, the spring element is restrained at the top by a top molding, which is connected to the casing arranged at the bottom, the seat being fastened on the top molding. In an alternative variant, the casing, which is positioned on the spring element from above, is fixed to the outer sleeve, it being possible for the casing to have a flange for connection to the seat.
- The axial through-passage preferably narrows conically. Provided in the top molding or in the casing, which is positioned on the spring element from above, coaxially with the pneumatic-spring-forming central column, is a through-opening for the purpose of actuating the triggering push rod of the pneumatic spring. In order to limit the moveability of the seat, the through-opening in the top molding or the casing, which is positioned on the spring element from above, has a defined geometry, e.g. a slot. The internal core of the spring element then has an extension which projects into the through-opening and is guided therein.
- The specific advantages of the mounting according to the invention are the result of the above set object being achieved, i.e. of the improvements for the user in terms of functioning and costs and of the design-related and cost-related effects for the manufacturer.

- A number of exemplary embodiments of the seat mounting according to the invention are described in detail hereinbelow with reference to the attached drawings.
- FIG. 1
- The chair comprises an
underframe 1, in this case a conventional star-shaped base, from the center of which acentral column 2 extends vertically. Thecentral column 2 may be an unalterable support or may contain an axially acting spring, e.g. a helical spring, a pneumatic spring or a combination thereof. Thecentral column 2 has positioned on it theseat 3—in this case in the form of a seat shell—in which the user sits. It would also be possible for the seat to be designed as a, for example, angled structure or as a stool top. - FIGS. 2A and 2B
- These figures illustrate the purpose of the invention schematically, namely to provide a mounting for a seat, including a chair, of which the seat allows a swinging movement in the horizontal plane, from a
rest position 0, in all directions R1 to RX, the maximum movement from therest position 0 being defined by the inclination angle α. For certain applications, the design can establish the possible directions R1 to RX—e.g. only laterally or from the front to the rear—as will be described at a later stage in the text. - FIG. 3
- The
underframe 1, thecentral column 2—typically a pneumatic spring—and a shell-like seat 3 are provided here. It is also possible to see a tubular pneumatic-spring covering 20 and a cylindrical push-rod extension 21. A triggeringlever 22 fitted beneath theseat 3 is provided for actuating thepneumatic spring 2. A first embodiment of the mounting comprises a first variant of aspring element 4, a bottom, cup-like casing 5 and atop molding 6, in this case in the form of a cover plate which is intended for fastening on the top side of the base of theseat 3. Finally, a seat-cushion panel 30, which covers thetop molding 6, is provided. Thespring element 4 is roughly cylindrical with reduced-diameter sections central section 42, anouter sleeve 43, acore 44 and an axial through-passage 45, the latter running through thecore 44. - FIG. 4A
- In the case of the first embodiment of the mounting, in the instooled state, the first variant of the
spring element 4 is accommodated, via thebottom section 41 and thecentral section 42, basically in a form-fitting manner by thecup part 50 of thecasing 5. Thetop section 40 is enclosed basically in a form-fitting manner by the shapedcollar 60 on the underside of thetop molding 6, said collar having complementary contours. Thespring element 4 is fitted, by way of its axial through-passage 45, on thepneumatic spring 2, which terminates conically at the top and has the push-rod extension 21 positioned axially on its triggeringpush rod 23, said extension projecting upward out of the axial through-passage 45, with the resuit that the triggeringlever 22 is located thereon. Provided in the plate-like molding 6, around the emerging push-rod extension 21, is acutout 61, which provides free space in all directions R1 to RX during swinging movement. Above thecup part 50, thecasing 5 has an outwardly oriented horizontal flange 51, on which theannular flange 62 of themolding 6, said flange projecting beyond the shapedcollar 60, rests and extends further outward by way of itsouter border 63. The shapedcollar 60 projects into thecup part 50. The flange 51 andannular flange 62, located thereon, are connected, e.g. screwed, to one another. Theouter border 63 is connected, e.g. likewise screwed, to the shell-like seat 3. Theseat shell 3 grips beneath thespring element 4, which is restrained between thecasing 5 and thetop molding 6. - FIG. 4B
- In the case of the
seat 3 being deflected from therest position 0 to the maximum possible inclination angle α, the elasticouter sleeve 43 of thespring element 4 is temporarily deformed in its restraint, as an increasing spring resistance develops. The deflection takes place by the action of force, namely by the user's weight shifting. - FIGS. 5A and 5B
- In the case of the first embodiment of the mounting, in contrast to the previous pair of figures, FIGS. 4A and 4B, use is made of a second variant of a
spring element 4. In this case, thecore 44 extends axially upward ascore continuation 440 and thus projects into thecutout 61. In the case of theseat 3 being deflected from therest position 0, thecore continuation 440 strikes against the border of thecutout 61 in the case of the maximum possible inclination angle α. The geometrical configuration of thecutout 61, in conjunction with the dimensions of thecore continuation 440, allows the maximum possible inclination angle α to be defined or movement directions to be determined, e.g. only to the side or only from the front to the rear. This can be achieved by a correspondingly slot-like cutout 61. It would also be possible for other, crosswise or diagonal movement patterns to be formed in such a way. - FIGS. 6A and 6B
- To complement the
central column 2—mostly the pneumatic spring—which terminates conically at the top, the axial through-passage 45 of thespring element 4 is likewise conical. In order to optimize the movement characteristics, it has been found to be advantageous for the core 44 in thespring element 4 to be widened as aradial bead 441 in the region of thecentral section 42. It is thus possible, in the case of a relatively high level of deflection from therest position 0, for material of the elasticouter sleeve 43 to be supported on theradial bead 441 and for a relatively high spring resistance to develop. In the case of the first variant of the spring element 4 (according to FIG. 6A), thecore 44 terminates with thetop section 40 of theouter sleeve 43. - The second variant of the spring element4 (according to FIG. 6B) with a
core continuation 440 is provided if the intention is to limit the swinging movement of theseat 3 to a maximum permissible inclination angle α or in accordance with a specific movement pattern. It would be possible for the elasticouter sleeve 43 to consist, for example, of a specifically suitable rubber mix, whereas thecore 44 is preferably metallic. - FIGS. 7A to9B
- A second embodiment of the seat mounting according to the invention is illustrated here. Once again, an
underframe 1, acentral column 2—preferably a pneumatic spring—aseat 3, thespring element 4, thebottom casing 5′ and atop molding 6′ are provided for this chair. The special feature here is that, rather than being formed by a separate plate, thetop molding 6′ is formed by a correspondingly contouredaperture 60′ in theseat carrier 6′. Theaperture 60′ encloses thetop section 40 of thespring element 4 in the same way as the shapedcollar 60. Thecutout 61′ is provided again in theseat carrier 6′. Thecasing 5′ is inserted into theaperture 60′ by way of its top border, is enclosed by theseat carrier 6′ and is connected to the latter, thespring element 4 being more or less encapsulated in the process. Thecutout 61′ provides the freedom of movement as deflection from therest position 0. - If use is made of the first variant of the spring element4 (according to FIG. 6A), as is the case with the arrangement in FIG. 9A, the moveability of the
seat 3 resting on thecentral column 2 is more or less unlimited. If use is made of the second variant of the spring element 4 (according to FIG. 6B) with thecore continuation 440, as the arrangement in FIG. 9B shows, it is possible to limit the movement as described above (see FIGS. 5A and 5B). - FIG. 10
- In the case of this third embodiment of the seat mounting, use is made of a third variant of a
spring element 4, which is likewise intended for fitting onto acentral column 2. The sheath-like core 44 has an axial through-passage 45 for accommodating the top end of thecentral column 2, preferably a pneumatic spring with a telescopically extensible lifting rod. It is advantageous if the axial through-passage 45, to complement the lifting rod, narrows conically upward. - The
core 44, consisting, for example, of steel, has anencircling shoulder surface 442, which is preferably produced by an outside cone with a diameter which tapers in an upwardly sloping manner. A conicalouter sleeve 43 made of elastic material, e.g. rubber, is arranged on theshoulder surface 442. Theouter sleeve 43 is enclosed by atop molding 600, with the result that the latter constitutes acasing 600 for theouter sleeve 43. In order to ensure optimum functioning, the core 44 should be fixed to theouter sleeve 43 and the latter should be fixed to thetop molding 600. Thespring element 4 is thus a three-part component, comprising thecore 44, theouter sleeve 43 and thetop molding 600. A seat fastened on thetop molding 600 can execute elastic movements in the horizontal plane by virtue of the elasticity of theouter sleeve 43, which is arranged between the core 44 and themolding 600. Provided in themolding 600, coaxially with the axial through-passage 45, is acutout 61″, which allows access for a triggeringlever 22 to the triggeringpush rod 23 of the pneumatic spring (see FIG. 4A). - FIGS. 11A and 11B
- In the case of the fourth embodiment of the seat mounting which is shown here, use is made of a fourth variant of a
spring element 4, which, once again, is fitted onto acentral column 2. Here too, the sheath-like core 44 has the preferably conical axial through-passage 45 for accommodating the top end of thecentral column 2. Once again, thecore 44 has theshoulder surface 442 encircling the outside, and the elasticouter sleeve 43, which in this case has a basically cylindrical outer circumference, is arranged on said shoulder surface. Themolding 600′, which covers over theouter sleeve 43 in a cup-like manner from above, is provided with aflange 601′ at the bottom. Thecore 44, theouter sleeve 43 and themolding 600′, which constitutes the casing, form thespring element 4. Fixed connections between the core 44,outer sleeve 43 andmolding 600′ are more or less imperative for the functioning. Aseat 3 fixed on themolding 600′, preferably on theflange 601′, can be moved elastically in the horizontal plane by virtue of the elasticity of theouter sleeve 43, as in the case of the previous designs. Thecutout 61″, once again, is provided above the axial through-passage 45 of themolding 600′ in order to provide access for a triggeringlever 22 to the triggeringpush rod 23 and/or a push-rod extension 21 of thecentral column 2, formed by the pneumatic spring.
