Definitions

  • the invention relates to a backrest device for a piece of furniture that is suitable for sitting and/or lying down.
  • the invention also relates to a piece of seating and/or reclining furniture with such a backrest device and with a seating or reclining element.
  • Modern seating or reclining furniture occasionally provides adjustment options to increase comfort for the user.
  • the adjustment options affect, for example, the user's head or back.
  • the backrest device according to the invention aims in particular to provide the possibility of supporting the head and back of a user according to needs and still offer an attractive appearance.
  • the piece of seating and/or lying furniture can in particular be a piece of upholstered furniture, such as an armchair, a sofa, a couch, a chaise lounge or a chaise longue.
  • the backrest device accordingly includes upholstery elements.
  • the backrest device comprises a backrest and a headrest.
  • the headrest is adjustable relative to the backrest between a first (retracted) position and a second (extended) position. Specifically, this is the possibility of linear adjustment along a translation axis.
  • the headrest has an overlap section which always overlaps with part of the backrest, so that There is no gap between the backrest and the headrest when the headrest is in the first position, the second position and an intermediate position (between the first and second positions). This means that regardless of its position, the headrest always overlaps with part of the backrest. Depending on the position of the headrest, the area of overlap is larger or smaller when viewed along the translation axis.
  • the linear adjustment therefore enables the backrest device to be adapted to the user's body size. Since there is no gap between the headrest and the backrest in any position of the headrest, the appearance is harmonious and the modular structure is not emphasized.
  • the overlap section is flat and extends in a main extension plane.
  • the overlap section extends over the entire width of the headrest.
  • the overlap section always overlaps with a part of the backrest, at least in the viewing direction perpendicular to the main extension plane.
  • the overlapping section can be arranged with respect to the backrest in such a way that the overlapping section covers a part of the backrest (viewed from a viewing direction of the side facing a user).
  • the translation axis can lie in the main plane of extension of the overlapping section of the headrest.
  • the translation axis and the main extension plane can enclose an angle of less than 90°.
  • the translation axis can lie in the main extension plane of the overlap section. If the backrest device is arranged as intended, the translation axis can be aligned vertically.
  • a plurality of intermediate positions are provided between the first position and the second position along the translation axis, which can be adjusted by linearly adjusting the headrest relative to the backrest along the translation axis.
  • the headrest can be lockable or lockable in any of the first position, the second position and any intermediate positions.
  • the headrest can be pivotable about an axis of rotation.
  • the rotation axis can be directed essentially perpendicular to the translation axis and extend along the width of the headrest. The swivelability of the headrest makes it possible to adjust the inclination of the headrest relative to the backrest.
  • the inclination for the head or for the upper body and the head as a whole can be adjusted.
  • the linear adjustment takes place manually.
  • the headrest can be moved upwards in order to lock into one of the intermediate positions or into the second position.
  • at least one rack can be provided, which interacts with at least one gear.
  • the at least one rack is aligned parallel to the translation axis.
  • a locking fitting can be provided which enables locking in one of the positions mentioned
  • the backrest device can comprise a motor for linear adjustment of the headrest, the motor acting on the headrest via a carrier.
  • the carrier may comprise a first carrier part, which is firmly connected to the headrest, and a second carrier part, which is linearly displaceable by the motor.
  • the first carrier part and the second carrier part can be detachably connected to one another. This allows the two carrier parts to be moved independently of each other under certain circumstances.
  • the releasable connection can be such that the first support part and the headrest connected to it are displaceable with the second support part when the first support part and the second support part are connected to one another by means of the releasable connection, and that the first support part and the headrest connected to it connected headrest cannot be moved with the second carrier part if the first carrier part and the second carrier part are not connected to one another by means of the releasable connection.
  • This embodiment can prevent the headrest and the first support part from moving with the second support part and, for example, a user, when the motor is in operation, which is about to effect a linear adjustment of the second support part from the second position to the first position hold the headrest.
  • the detachable connection between the first carrier part and the second carrier part can comprise a magnetic connection.
  • the motor can be hidden, in particular arranged in a receptacle that is formed in the backrest.
  • Figure 1 shows a perspective view of a backrest device 100 and a section of a seat element 200, which together with the backrest device 100 forms a piece of seating furniture 1 in the form of a sofa.
  • the seat element 200 includes a seat 201.
  • the seat 201 is padded.
  • the backrest device 100 includes a backrest 110 and a headrest 120.
  • the backrest 110 and the headrest 120 are also padded.
  • the headrest 120 is linearly displaceable relative to the backrest 110 along a translation axis T between a first (retracted) position and a second (extended) position.
  • the headrest 120 can also assume and be locked in one of several positions between the first and second positions.
  • Figure 1 the headrest 120 is shown in the first position.
  • Figure 2 shows the backrest device 100 Figure 1 , however, the headrest 120 is in the second position.
  • the headrest 120 always overlaps (both in the first and in the second position) in an overlapping section 124 with the backrest 110.
  • the extent of the overlap varies with the position of the headrest 120.
  • the overlapping section 124 always extends (i.e regardless of the position of the headrest 120) over the entire width of the headrest 124.
  • the extent of the overlap varies with the position of the headrest 120 only along the translation axis T.
  • the headrest 120 can be pivoted about an axis of rotation R in order to adjust the angle between the headrest 120 and the backrest 110.
  • the rotation axis R extends substantially perpendicular to the translation axis T and along the width of the headrest 124.
  • Figs Figures 3 and 4 is the Headrest 120 pivoted about the axis of rotation R is shown, the rotation starting from the second position of the headrest 120 ( Figure 2 ) has been made.
  • the angle between the headrest 120 and the backrest 110 can vary between 0° and 40°. Several intermediate positions are provided.
  • the headrest 120 can be locked (latched) both in the intermediate positions and in the two outermost deflections.
  • the angle between adjacent positions is 4°.
  • eleven different inclinations of the headrest 120 can be adjusted by rotating it about the rotation axis R. Even if the angle between the headrest 120 and the backrest 110 varies, the headrest 120 always overlaps with the backrest 110 in an overlap section 124.
  • the backrest 110 and the headrest 120 each comprise a solid base body.
  • the base body of the backrest 110 defines a receptacle 113.
  • Two through openings 111 are incorporated into the base body of the backrest 110, each of which serves to receive a guide shaft 121 which is arranged on the headrest 120.
  • a plug-in sleeve 112 is arranged in each feed-through opening 111, which covers the corresponding feed-through opening 111 and offers defined sliding properties in relation to the guide shaft 121.
  • the plug-in sleeve 112 is connected to the feed-through opening 111 in a form-fitting manner, for example by a (spring-mounted) projection 1121 at one end and a projecting decorative cap 1122 at another end ( Figure 13 ).
  • the socket 112 is in detail Figure 14 shown.
  • Figure 15 shows a detailed representation of the guide shafts 121.
  • fittings 122 are arranged, which serve to fasten the respective guide shaft 121 to the headrest 120.
  • Each fitting 122 is attached to the respective guide shaft 121 via a joint 123.
  • the fitting 122 and the joint 123 are designed together as a locking fitting.
  • the translation mechanism 130 includes two racks 131, each of which interacts with a gear 132.
  • the racks 131 extend along the translation axis T. While the racks 131 are stationary, the gears 132 are adapted to extend along the racks 131 to move.
  • the racks 131 are arranged at a distance from one another and are connected to one another via a first cross strut 133.
  • the cross strut 133 is according to Figures 6 and 7 for example, arranged in an end region of the racks 131.
  • FIG. 6 shows the translation mechanism 130 corresponding to the first position of the headrest 120. That is, when the headrest 120 is retracted.
  • FIG. 7 shows the translation mechanism 130 corresponding to the second position of the headrest 120. That is, when the headrest 120 is extended. In this position, the second crossbar 134 is in its uppermost position.
  • the second crossbar 134 can assume a variety of positions between the top and bottom positions, and thus the headrest 120 can be locked (locked) at different heights.
  • the locking fitting 135 can comprise 23 locking positions.
  • the height difference between the top position of the second crossbar 134 and the bottom position of the second crossbar 134 can be 15 cm. Other height differences are also conceivable.
  • the headrest 120 In order to transfer the headrest 120 from a lower position to a higher position, it is sufficient to pull the headrest 120 upwards. In order to transfer the headrest 120 from a position further up to a position further down, the headrest 120 must first be brought into its second position (uppermost position of the second cross strut 134) in order to release the locking fitting 135 from its locking state, so that the headrest 120 can then move downwards into its first position (lowest position of the second crossbar 134).
  • the backrest device 100 can include a translation mechanism 140 for a motor-driven linear adjustment of the headrest 120.
  • This translation mechanism 140 is in its installed state in the base body of the backrest 110 Figure 8 shown.
  • Figure 9 shows the translation mechanism 140 Figure 8 alone.
  • the translation mechanism 140 includes a bracket 141 which is provided for fastening the translation mechanism 140 in the backrest 110.
  • a motor 143 is attached to the bracket 141 via a linear guide 142.
  • the linear guide 142 extends along the translation axis T.
  • the linear guide serves to guide a carrier 144, which in the embodiment of Figures 9 to 12 is designed in two parts.
  • the carrier 144 includes a first carrier part 1441, which is connected to a crossbar 145 to which the headrest is attached, and a second carrier part 1442, which is linearly displaceable by the motor 143.
  • the crossbar 145 extends transversely to the translation axis T and along the width of the headrest 124.
  • Figure 9 illustrates the translation mechanism 140 in a configuration that corresponds to the first position of the headrest 120.
  • Figure 10 shows the translation mechanism 140 Figure 9 without the bracket 141 and in a view rotated by 180 ° about the translation axis T.
  • Figure 11 shows the translation mechanism 140 Figure 10 , however, the configuration corresponds to that of the second position of the headrest 120.
  • the first and second carrier parts 1441, 1442 can be clearly seen.
  • the motor 143 drives the second carrier part 1442.
  • the first carrier part 1441 which is connected to the second carrier part 1442 via a releasable connection, moves together with the second carrier part 1442 ( Figures 10 and 11 ).
  • the movement of the second support part 1442 can be decoupled from that of the headrest 120 (connected to the first support part 1441 via the cross strut 145) by applying a force ( Figure 12 ).
  • the detachable connection is such that, on the one hand, the first carrier part 1441 and the headrest 120 connected to it are displaceable with the second carrier part 1442 when the first carrier part 1441 and the second carrier part 1442 are connected to one another by means of the detachable connection, and that on the other hand first carrier part 1441 and the headrest 120 connected to it cannot be displaced with the second carrier part 1442 if the first carrier part 1441 and the second carrier part 1442 are not connected to one another by means of the releasable connection.
  • the detachable connection By releasing the detachable connection, it is possible to prevent the headrest 120, the cross strut 145 and the first support part 1441 from coming into contact with the second support part when the motor 143 is in operation, which causes a linear adjustment of the second support part 1442 in the direction of the first position of the headrest 120 1442 move. This can, for example, prevent a user who is holding the headrest 120 from being caught by the lowering headrest 120 injured especially trapped.
  • the detachable connection therefore has the function of a pinch protection.
  • the detachable connection is designed, for example, as a magnetic connection.
  • the magnetic connection can be such that it releases with a counterforce of 9 kg, so that although the second carrier part 1442 can be adjusted linearly by the motor 142, the first carrier part 1441 does not move with the second carrier part 1442.
  • the translation mechanism 130, 140 is arranged in the receptacle 113 of the backrest 110.
