Definitions
- the invention relates to a seat, in particular a work seat, for example an office chair or driver's seat, with a seat support and a backrest support which is L-shaped in the side view, one leg of the backrest support engaging under the seat support and on the underside thereof with the latter Swivel axis is pivotally connected.
- a work seat for example an office chair or driver's seat
- a backrest support which is L-shaped in the side view, one leg of the backrest support engaging under the seat support and on the underside thereof with the latter Swivel axis is pivotally connected.
- Such a seat is known, for example, from European Patent 0 022 933.
- the inclination of the backrest is adjusted with the aid of a gas spring, which is effective between the leg reaching under the seat support and the seat foot.
- the gas spring must be opened using an operating lever.
- Travel seats for rail vehicles are also known in which the backrest support can be pivoted relative to the seat support about a pivot axis located at the rear end of the seat support in the manner of a folding knife.
- the backrest support is therefore not L-shaped in the side view, but rather consists only of one leg compared to the L-shaped backrest support.
- the seat support and the backrest support are guided in rails such that when the seat support moves forward, the backrest support folds in the direction of the horizontal extent until the seat becomes a lounger.
- the upper end of the backrest support moves vertically downward, so that at the end of the folding movement the seat support is moved forward by the length of the backrest support.
- Such a travel seat is known from German Patent 20 54 817.
- Such a travel seat is fundamentally not suitable as a work seat, for example as an office chair, because the forward movement of the seat carrier required to achieve a certain backrest inclination is too great.
- the inclination of the backrest or the back of the seat user is achieved only in that the seat user slides forward with the seat support by a correspondingly large amount. Applied to an office chair, this would result in the seat user moving the office chair backwards by a correspondingly large amount must move if he does not want to change the distance to a worktop.
- the office chair would have to be supported on the floor over a very large area so that it can take into account the large horizontal movement of the center of gravity when the backrest is tilted.
- the invention is based on the object of creating a seat which is also suitable as a work seat, in which the inclination of the backrest can be adjusted simply by changing the position of the seat user without manual actuation, and in which the backrest is nevertheless at any inclination, apart from possible upholstery , the seat user offers a rigid back support.
- a work seat is created, the backrest inclination of which automatically adjusts when the seat user moves a little forward or backward with the seat support, with the additional advantage of this comfortable adjustment possibility while at the same time rigidly supporting the back of the seat user that the pivot point about which the seat user rotates when adjusting the backrest inclination can be held largely stationary at chest or stomach height at a short distance from the seat user.
- the pivot axis between the seat support and the backrest support is so far apart from the rear end of the seat support that the pivot point between the upright leg of the backrest support forming the actual backrest and the seat support comes to lie in an area in which the pivot point of the back of the seat user is at one Change of Inclination of the back.
- the disadvantage is avoided that a shirt is removed from a seat user when he tilts the backrest part backwards and remains seated and leans with his back against the backrest.
- the inclination of the pair of rails is preferably adjustable.
- the path which the backrest support, in particular its uppermost end, travels during an inclination adjustment can of course be changed.
- the arrangement can be made such that in one adjustment of the pair of rails when the backrest is tilted, the uppermost end of the backrest extends backwards while the seat support moves forward (division of the tilt change into two opposite directions of movement), whereas in another setting of the pair of rails does not move the top end of the backrest support backwards when the incline of the backrest support is adjusted, but rather moves downwards along a vertical line, as is already known, for example, from German Patent 20 54 817.
- a seat By a simple measure, namely adjusting the inclination of the pair of rails, a seat can thus be created which can be used, for example, as a so-called row seat in passenger transport means such as the train, where the rows of seats are arranged one after the other and it is desirable that the pivot point about which the seat user rotates during an inclination adjustment practically does not change, but which, on the other hand, can also be used as a so-called compartment seat in passenger transport means such as the train, which is arranged on a wall of the compartment and the latter Then backrest can no longer swing out, as is also described in the aforementioned German patent 20 54 817.
- the leg which extends under the seat support is expediently guided in a further pair of rails at the point remote from the pivot axis.
- the seat support is also guided at a point remote from the common pivot axis of the seat support and backrest support.
- This guide preferably consists of a stationary support, which in a special embodiment is a rotatable roller on which the seat support rests with its end remote from the common pivot axis of the seat support and backrest support.
- Guide pins or, even better, guide rollers preferably engage in the two pairs of rails which guide the backrest support.
- FIG. 1 the construction principle of a seat according to the invention is shown schematically.
- An L-shaped backrest support 10 engages with its lower leg 10a under a seat support 12.
- a pivot axis 14 is provided below the seat support, about which the seat support 12 and the backrest support 10 can be pivoted relative to one another.
- the ends of the pivot axis 14 are, as shown schematically, in a stationary pair of rails 16 which runs downward in the horizontal viewing direction of the seat user.
- the solid lines represent the position of the backrest support and seat support in the upright position of the seat according to the invention, while the rest position of the seat according to the invention is shown in broken lines, i.e. the position with the greatest backrest angle. From this schematic drawing it is clear that to adjust the inclination of the backrest, the seat support 12 must be moved forward, which a person sitting on it can easily do, whereupon the backrest support 10 inevitably tends to swing backward as shown. The uppermost end of the backrest support 10 thus moves in the opposite direction compared to the foremost end of the seat support 12.
- the inclination movement of the backrest of the seat according to the invention is thus divided into two oppositely directed movements of the seat support and backrest support, which among other things allows a space-saving arrangement of such seats as row seats in means of passenger transportation such as airplanes and trains.
- the center of gravity hardly moves when the backrest inclination is divided by dividing the inclination movement into two oppositely directed movements, so that such a seat, if it is to be used, for example, as an office chair, does not have any overhanging cantilevers to support it Feet needed.
- FIGS. 2a and 2b Another advantage which is achieved by dividing the inclination movement of the backrest into two opposite directions of movement can be seen from a comparison of FIGS. 2a and 2b.
- Fig. 2a the adjustment of the backrest inclination is shown in a conventional seat, in which the inclination movement of the backrest is not divided into two oppositely directed movements of the seat support and backrest support.
- FIG. 2a this has the consequence that the seat user moves away from a worktop when the backrest inclination is adjusted.
- the fulcrum around which his torso moves thus moves with the backward movement of the backrest.
- the situation in the seat according to the invention which is shown in FIG. 2b, is fundamentally different.
- the backward movement of the backrest is, so to speak, compensated for by the forward movement of the seat support, so that the pivot point of the upper body of the seat user hardly moves when the backrest angle is adjusted and this remains at stomach level near his worktop.
- the location of the pivot point D and its path, which it describes when the backrest is adjusted, is, as the person skilled in the art recognizes, the course of the pairs of rails 16 and 20 in which the backrest support 10 is guided at two spaced apart locations (14 and 18) is set.
- the pivot point D is placed through a corresponding course of the pairs of rails 16 and 20 such that it lies close to the driver's arm joints when the driver is in normal posture, so that the driver makes an adjustment the seat angle does not have to tighten or stretch the arms, so it largely maintains the position to the steering wheel. So far, the driver's seat had to be adjusted lengthways to achieve this goal.
- the distance x of the pivot axis 14 shown in FIG. 1 from the rear end of the seat support has the result that the pivot point between the upright leg of the backrest support 10 and the seat support 12 comes to lie in an area in which the pivot point of the back of the seat user a change in the inclination of the back.
- the disadvantage is avoided that a shirt is removed from a seat user when he tilts the backrest part backwards and remains seated and leans with his back against the backrest.
- pairs of rails 16 and 20 which are formed separately from one another in FIG. 1 can also be in the form of a single continuous pair of rails, as can be readily seen without giving up the advantages mentioned above.
- the seat according to the invention can be designed as an office chair, as a driver's seat or for any other type of seat.
- the possibilities of variation are also very large for the person skilled in the art.
- the only thing of decisive importance in any seat construction according to the invention is that the ends of the pivot axis of the backrest support and seat support are guided in a pair of rails in order to adjust the inclination of the backrest and the legs reaching under the seat support are guided at a point remote from the pivot axis in such a way that during forward movement the free end of the other leg moves in the opposite direction and downwards.
- a railway seat constructed according to the invention which can be used both as a so-called row seat with several rows of seats arranged one behind the other and as a so-called compartment seat, which is placed as close as possible to a wall of a train compartment.
- the railway seat shown has a base frame 24 to be fastened to the floor (see FIG. 3), to which the two pairs of rails 16 and 20 (see FIG. 1) are fastened.
- the special feature here is that the pair of rails 16 can be pivoted about an axis 26 provided at its upper end, the lower end being guided in guide slots 30 by means of pins 28.
- the pair of rails 16 can be locked in the end positions which are reached at the two ends of the guide slots 30.
- the backrest support 10 can be inserted with the ends of its pivot axis 14 into the pair of rails 16, wherein at the same time the guide pins 18 of the lower leg 10a of the backrest support 10 engage in the pair of rails 20.
- the seat behaves as required by the invention, i.e. its backrest swings out to the rear when its seat is moved forward, as shown in FIGS. 4 and 5.
- the pair of rails 16 can be used as a so-called row seat.
- the pivot axis 14 is moved forward so far when the seat is moved forward that the backrest support in its upper region can no longer move backwards, but rather sinks along a vertical approximately downwards. This course of movement can be seen in FIGS. 6 and 7. With this setting of the pivot axis 16, the seat can then be used as a so-called compartment seat.
- the seat according to the invention can be used as a so-called row seat or as a so-called compartment seat by a simple technical measure.
