  • To adjust the headrest this is usually pivoted manually between the Einklappstellung and the Ausklappstellung. These positions and other positions of the headrest can be defined and supported by stops and / or a locking function of the swivel fitting.
  • Against this background, the task is to increase the comfort of the operation of the headrest.
  • The object is achieved by a sitting / lying furniture with the features of claim 1.
  • Advantageous developments of the invention are also described in the subclaims and the figures.
  • 1 and 2 show in a cross section the backrest and the headrest of an embodiment of a sitting / lying furniture according to the invention in the folded position ( 1 ) as well as in the Ausklappstellung ( 2 ) of the headrest.
  • 3 and 4 show in a cross section the backrest and the headrest of another embodiment of a sitting / lying furniture according to the invention in the folded position ( 3 ) as well as in the Ausklappstellung ( 4 ) of the headrest.
  • Both illustrated in the figures embodiments of a sitting / lying furniture according to the invention 11 each include a backrest 13 which is arranged substantially vertically, and a headrest arranged thereon 15 between a substantially horizontal orientation (Einklappstellung, 1 and 3 ) and a substantially vertical orientation (Ausklappstellung, 2 and 4 ) is pivotable.
  • The backrest 13 is essentially as a carrier, base part or hollow body 17 formed on at least one outer side (in the figures, the left outer side) a padding 19 having. On the hollow body 17 fixedly arranged is a swivel fitting 21 that has a connecting section 23 and a storage section 25 having, wherein the connecting portion 23 from the inside of the hollow body 17 protrudes and so the hollow body 17 with the storage section 25 combines. The storage section 25 is essentially as a bearing for a wave 27 the headrest 15 designed so that the headrest 15 about a pivot axis S passing through the shaft 27 is defined, pivotally mounted and the pivot fitting 21 with the backrest 13 connected is.
  • The headrest 15 is essentially a base plate 29 formed, which at least to one side a padding 31 having. The headrest 15 can be pivoted between the Einklappstellung and Ausklappstellung by an angular range, for example, between 70 ° and 120 °, preferably at least 90 °, so that a transition between a horizontal and a vertical position can be achieved. In particular, the angular difference between the Einklappstellung and Ausklappstellung as shown may be about 108 °, the headrest in the Ausklappstellung ( 2 and 4 ) is pivoted beyond the vertical.
  • In the embodiment according to the 1 and 2 includes the connecting portion 23 of the swivel fitting 21 two angled chrome rods, which at least in the Ausklappstellung ( 2 ) of the headrest 15 behind the headrest 15 visible from the backrest 13 out and in the headrest 15 extend into it (under the viewing angle shown in the figures, ie in the illustrated side view, one of the chrome bars is covered by the other). The chrome poles are deliberately designed as visible design elements and contribute to the appearance of the sitting / lying furniture.
  • The backrest 13 and the headrest 15 with their respective upholstery 19 . 31 are of respective separate references 33 respectively. 35 surrounded while the swivel fitting 21 at least with parts of the connecting portion 23 visible outside the backrest 13 and the headrest 15 and their references 33 respectively. 35 runs.
  • In contrast to this embodiment, in the embodiment according to the 3 and 4 the backrest 13 and the headrest 15 from a common reference 33 . 35 surrounded, with the respective upholstery 19 . 31 seamlessly blend into each other so that the backrest 13 , the swivel fitting 21 and the headrest 15 appear outwardly formed as one piece. In order to avoid in this embodiment that when unfolding the headrest 15 the reference 33 . 35 at the transition between the padding 19 the backrest 13 and the upholstery 31 the headrest 15 Folds, points the base plate 29 the headrest 15 a mechanics 37 on, by unfolding the headrest 15 to an extension of the base plate 29 So to an extension of the headrest 15 , leads, so that the reference 33 . 35 is streamlined.
  • In addition to the swivel fitting 21 , which is a simple axis of rotation for pivoting the headrest 15 is between the backrest 13 and the headrest 15 a motor fitting 39 for motorized pivoting of the headrest 15 intended. This engine fitting 39 includes a motor 41 that is attached to the backrest 13 is attached and an output element 43 that is from the engine 41 can be adjusted to a linear adjustment movement between an engagement position and a disengagement position. At the output element 43 it may be, for example, a reciprocating piston or a rotating spindle.
  • In addition, the engine fitting includes 39 a toggle assembly 45 about which the initial element 43 of the motor 41 with the headrest 15 is connected, so that an adjusting movement of the engine 41 to a pivoting movement of the headrest 15 can be derived. In this case, in the embodiments shown, the disengagement position in which the output element corresponds 43 maximum from the engine 41 protrudes, the Ausklappstellung the headrest 15 and corresponds to the engagement position in which the output element 43 minimal from the engine 41 protrudes, the Einklappstellung the headrest 15 , However, embodiments are also possible in which this relationship is just the opposite, ie the engagement position corresponds to the Ausklappstellung and the disengagement corresponds to the Einklappstellung.
  • The toggle lever assembly 45 includes at least one lever 47 and at least one drive lever 49 which are hinged together. The lever 47 is in each case about a deflection axis U pivotally mounted on the backrest 13 stored. For this purpose, in particular a mounting plate 51 inside the hollow body 17 the backrest 13 be provided. Furthermore, the respective reversing lever 47 an entrance section 53 with which the bellcrank 47 at the output element 43 of the motor 41 is articulated, and an output section 55 on, with the bellcrank 47 hinged with one end of the drive lever 49 connected is. With the opposite end of the integrally formed drive lever 49 again at a drive point 57 the headrest 15 hinged, which is spaced from the pivot axis S.
  • In this way, a motorized adjustment of the output element 43 of the motor 41 at the entrance section 53 of the reversing lever 47 be taken and to pivot the bellcrank 47 lead to its deflection axis U. As a result, the adjusting movement becomes a defined arcuate movement of the output section 55 diverted. The exit section 55 in turn, in this way, the drive lever 49 drive, so that the adjustment movement finally to the drive point 57 the headrest 15 is transmitted. Because the drive point 57 the headrest 15 from the pivot axis S to the headrest 15 is pivotally mounted, is spaced, which leads from the toggle lever assembly 45 on the drive point 57 transmitted adjusting movement of the output element 43 of the motor 41 thus to a pivoting of the headrest 15 ,
  • This basic mechanism is implemented in both embodiments shown in the figures. The specific kinematics results in each case from the suitably selected shape and arrangement of the deflection and drive lever 47 . 49 , By their interaction, the linear adjustment movement of the engine 41 insofar along particularly suitable courses within the sitting / lying furniture 11 to a pivoting movement of the headrest 15 are derived as the toggle assembly 45 particularly inconspicuous, especially invisible from the outside, possibly within the backrest 13 or the headrest 15 can be performed.
  • For attachment to the backrest 13 points the engine 41 a fixing section 59 on which he leans against. Advantageously, the attachment portion allows 59 an attachment of the engine 41 on the backrest 13 such that the engine 41 at least in a certain range pivotable about the attachment portion 59 on the backrest 13 is appropriate. Thus it is the linearly adjustable output element 43 of the motor 41 possible to deviate to some extent laterally to the linear adjustment direction. This is required by the fact that the input section 53 of the reversing lever 47 due to the pivotable mounting of the reversing lever 47 around the deflection axis U can not be adjusted purely linear, but is forcibly guided on a circular arc path.
  • Overall, form the attachment section 59 of the motor 41 , the deflection axis U of a respective reversing lever 47 and the pivot axis S of the swivel fitting 21 the fixed points for the positively driven transmission of the adjusting movement of the motor 41 over the toggle lever assembly 45 on the headrest 15 ,
  • In contrast to the embodiment of the 3 and 4 in which a single lever 47 is provided, comprises the toggle lever assembly 45 the embodiment according to the 1 and 2 two identical trained and oriented lever 47 whose output sections 55 at a distance from each other on the drive lever 49 are articulated, which corresponds to the distance of the respective deflection axes U. In this way, the two levers form 47 with the drive lever 49 a four-bar linkage, through which the drive lever 49 so It is forcibly guided that he merely changes his position, but not his orientation in space. In each case, the toggle lever assembly 45 the two levers 47 Aligned relative to each other substantially the same.
  • Furthermore, in the embodiment of the 1 and 2 in the Ausklappstellung the headrest 15 the exit sections 55 and the respective deflection axis U of the two lever 47 just arranged essentially on a line, eliminating the headrest 15 stabilized particularly well in this position. This contributes in particular to the fact that the drive lever 49 from the headrest 15 out oblong towards the backrest 13 extends and after a slight bend substantially along the said line.
  • The embodiment according to 3 and 4 on the other hand, only has one reversing lever 47 on. A stabilization of Ausklappstellung the headrest 15 is here also achieved in that the articulated lever assembly is formed in the manner of a toggle lever and the Ausklappstellung is achieved by overcoming a dead center. Furthermore, it is advantageous for the stabilization that in the Ausklappstellung the attachment portion 59 and the starting element 43 of the motor 41 , the entrance section 53 and the exit section 55 of the reversing lever 47 and the drive lever 49 with its two ends arranged substantially on a line. Furthermore, the toggle lever assembly 45 have a Selbstblockadefunktion, so that pivoting of the headrest 15 is blocked beyond a certain point, as for the in 4 Ausklappstellung shown is the case.
  • In the embodiment according to 3 and 4 in which the backrest 13 , the headrest 15 and the swivel fitting 21 from a common reference 33 . 35 surrounded, is the engine fitting 39 from the outside in any of the positions of the headrest 15 visible as it is completely within the reference 33 . 35 is arranged. These are in particular the drive lever 49 and at least one between the deflection axis U and the output portion 55 extending leg of the bellcrank 47 appropriately bent. Preferably, the engine fitting 39 by the reference 33 . 35 also not visible to the outside insofar as it has at least essentially no influence on the surface course of the cover 33 . 35 Has. In this way, the design of the embodiment according to 3 and 4 by providing the engine fitting 39 for comfortable motorized adjustment of the headrest 15 not impaired.
  • Although in the embodiment according to 1 and 2 the backrest 13 and the headrest 15 separate with separate padding 19 . 31 trained, however, allows close to the headrest 15 guided course of the drive lever 49 Also in this embodiment, at least substantially not visible from the outside arrangement of the drive lever 49 , For this purpose, the drive lever 49 completely or at least partially in the from the backrest 13 outstanding area of the reference 35 the headrest 15 or an additional cover or a suitable covering. Thus, only the pivot fitting runs 21 partially, namely with the formed as angled chrome rods connecting portion 23 , visible outside the headrest 15 and the backrest 13 , Thus, also in this embodiment, the design of the sitting / lying furniture 11 through the engine fitting 39 not affected in comparison to the appearance of a corresponding sitting / lying furniture without engine fitting.
  • In particular, the engine fitting is suitable 39 both in the embodiment according to 1 and 2 as well as in the embodiment according to 3 and 4 For optional or subsequent installation in a corresponding sitting / lying furniture 11 whose headrest 15 initially not motorized adjustable. Except for a possibly required provision of a suitable drive point 57 on the headrest 15 and a mounting plate 51 in the hollow body 17 the backrest 13 are thus advantageously no modifications, in particular no externally disturbing perceptible modifications of an existing sitting / lying furniture 11 to prepare for the installation of a motor fitting 39 required.
