Definitions

  • the invention relates to seating furniture with a stand-up aid.
  • an armchair with a stand-up aid is that the armchair can be lifted and moved forward using a remote control or a control button, so that the owner can easily get up from the cushions.
  • This functionality is particularly gentle on the back, as no sudden effort is required when standing up.
  • this mechanism also makes it possible to sit down particularly gently and comfortably.
  • Such armchairs are often designed as so-called relaxation armchairs, which also offer the possibility of extending a footrest and tilting the backrest backwards.
  • Several actuators are often used to implement the various positions of the seating furniture. In order to reduce the electrical outlay, however, it has also been proposed that both the stand-up aid and the extension of the footrest and the actuation of the seat/backrest adjustment mechanism be carried out with just one actuator.
  • a corresponding armchair is known, for example, from DE 20 2019 100 213 U1 .
  • Activation of the actuator in a first direction activates the stand-up aid. If, on the other hand, the actuator is actuated in the second direction starting from the upright basic position, on the one hand the footrest is extended and the seat and the backrest are adjusted into a reclined position.
  • BE 1 018 255 A3 and DE 200 00 926 U1 make use of a reversable actuator to activate a stand-up aid, to activate the footrest and to position the seat into a first reclined position and a second reclined position.
  • US 9 241 855 B2 discloses a furniture member including a frame, a slide member, first and second bars, an axle, and first and second leg members.
  • the frame includes a chair portion movable relative to a base among nominal, reclined and lift positions.
  • the invention was based on the object of further improving the comfort of the seating furniture without having to provide additional actuators.
  • the object is achieved by a piece of seating furniture with the following features:
  • the base frame of the seating furniture has a first frame part and a second frame part that are hingedly connected to one another about a transverse axis, the tilting mechanism being designed for relative adjustment of the first and second frame parts around the transverse axis.
  • the seat-backrest adjustment mechanism has a stop element that blocks further rotation of the backrest relative to the seat between the reclined position and the tilted position, so that the angle between seat and backrest in the reclined position is the same as in the tilted position.
  • the upright basic position of the seating furniture is understood to mean a position in which the seat is oriented essentially horizontally, i.e. at an angle of 0° +/- 10° with respect to the horizontal.
  • the backrest is essentially vertical or aligned at an angle of 0° +/- 10° to the vertical.
  • a raised position is understood to mean a position in which at least the rear region of the seat is raised, so that a seat surface that is slightly inclined forward results.
  • the angle between the seat and the backrest can remain essentially unchanged between the upright basic position and the raised position.
  • the seat In the raised position, the seat essentially has an angle in the range of 25° +/- 20° with respect to the horizontal.
  • the reclined position of the seating furniture is characterized on the one hand by the extended footrest and a backrest that is inclined backwards.
  • the front region of the seat is preferably arranged somewhat higher than in the upright basic position. In the reclined position, there is in particular an increase in the angle between the seat and the back surface compared to the upright basic position.
  • An angle between the seat and the backrest in the reclined position of 120° +/- 20° is considered particularly pleasant.
  • the tilted position is primarily characterized in that the footrest is at a greater distance and the backrest is at a smaller distance from the standing surface.
  • the tilt position promotes blood circulation and the breakdown of fluid accumulations in the lower extremities. It can also optionally be provided that the distance between the footrest and the standing surface in the tilted position is approximately equal to or greater than the distance between the backrest and the standing surface, in order to further intensify this effect.
  • the actuator is designed as a linear actuator, which is coupled with a first end to the base frame and a second end to the seat.
  • the base frame can have a rotatably mounted shaft extending transversely to the seating furniture, the actuator being coupled with a first end to the shaft for rotating the same.
  • the shaft when the actuator is actuated in the first direction, the shaft is rotated as far as a first stop, which blocks further rotation of the shaft such that further actuation of the actuator in the first direction activates the stand-up aid for raising the seat and the backrest into the raised position.
  • a second stop connected to the seat or to the seat-backrest adjustment mechanism can be provided, which blocks further rotation of the shaft in the event of active contact with the shaft when the actuator is actuated in the second direction, whereby with a further actuation the adjustment of the seat and backrest in the inclined position is triggered.
  • the tilting mechanism has at least one lever linkage, one end of which is non-rotatably attached to the shaft and the other end of which is hingedly coupled to the second frame part of the base frame, with further actuation of the actuator in the second direction, starting from the reclined position, leading to rotation of the shaft and a resulting relative adjustment of the first and the second frame part about the transverse axis.
  • the at least one lever linkage can have a first actuating lever and a second actuating lever, the first actuating lever being non-rotatably attached at one end to the shaft that is rotatably mounted on the first frame part and being hingedly coupled at its other end to the second actuating lever, which in turn is hingedly connected to the second frame part of the base frame.
  • the first frame part can have two front supporting feet, two rear supporting feet and two rear standing rollers, the base frame being supported in the raised position, in the upright base position and in the reclined position on the front supporting feet and the rear supporting rollers of the first frame part L4.
  • the second frame part has front standing rollers which are used in the tilted position, in which the base frame is supported on the front standing rollers of the second frame part and the rear feet of the first frame part on the standing surface.
  • the rear supporting feet ensure that the seating furniture is held securely, while the front standing rollers roll on the standing surface during the tilting process, thus enabling the distance between the front standing rollers of the second frame part and the rear supporting feet of the first frame part to be shortened and thus the two frame parts to be adjusted relative to one another.
  • the base frame is supported in an intermediate position both on the front standing rollers of the second frame part and on the rear standing rollers of the first frame part, thereby enabling the seating furniture to be moved easily.
  • This intermediate position is expediently a position that can be approached separately by remote control or operating button, which can then be used when the seating furniture is to be adjusted in the room.
  • the standing rollers on the first frame part can also be omitted so that the base frame is supported in the raised position, in the upright base position and in the reclined position on the front and rear supporting feet of the first frame part and the base frame is in the tilted position on the front standing rollers of the second frame part and the rear supporting feet of the first frame part.
  • Fig. 1 shows a piece of seating furniture according to the invention in its upright basic position. Essentially only the mechanics are shown, so that in particular padding and side bolsters have been omitted to better explain the invention.
  • the seating furniture has a seat 1, a backrest 2 and a footrest 3. Furthermore, a base frame 4 is provided for supporting the seating furniture on a standing surface 5.
  • a stand-up aid 7 is activated for lifting the seat 1 and the backrest 2 from the upright basic position according to Fig. 1 to a raised position according to Fig. 2 .
  • a footrest adjustment mechanism 8 is activated for extending the footrest 3 into the position shown in Fig. 3 .
  • the front end of the seat 1 is also slightly raised.
  • a further actuation of the actuator 6 in the second direction activates a seat adjustment mechanism 91 and a backrest adjustment mechanism 92, whereby the seat 1 and the backrest 2 are adjusted into the reclined position shown in Fig. 4 .
  • a further actuation of the actuator 6 in the second direction causes the actuation of a tilting mechanism 10, whereby the seat 1 and backrest 2 are tilted into the tilted position shown in Fig. 5 .
  • the tilting mechanism 10 causes the footrest 3 to be raised and a headrest 21 integrated in or separate from the backrest 2 to be lowered with respect to the standing surface 5.
  • the base frame 4 is described in more detail below with reference to Fig. 4 , 5 and 6 . It consists essentially of a first frame part 41 and a second frame part 42, which are hingedly connected to one another around a transverse axis 43. The base frame 4 also has a fastening flange 44 which is fixedly arranged in a central region of the first frame part 41 and extends upward from the standing surface 5.
  • the first frame part 41 provides two front supporting feet 45, two rear supporting feet 46 and two rear standing rollers 47, the base frame 4 being supported in the raised position, in the upright basic position and in the reclined position on the front supporting feet 45 and the rear standing rollers 47 of the first frame part.
  • the second frame part 42 only has front standing rollers 48, which are only used during the tilting process, so that the base frame is supported in the tilted position according to Fig. 5 on the front standing rollers 48 of the second frame part 42 and the rear supporting feet 46 of the first frame part 41 on the standing area 5.
  • the rear standing rollers 47 of the first frame part 41 are therefore fastened between the front supporting feet 45 and the rear supporting feet 46 on the first frame part 41.
  • the rear supporting feet 46 define the pivot point about which the seating furniture tilts backwards during the tilting process.
  • the front standing rollers 48 of the second frame part 42 roll on the standing surface 5 during the tilting process.
  • the base frame 4 also has a swivel frame 49, which is shown in more detail in Fig. 7a to 8b . It essentially consists of two lateral swivel levers 491, 492 parallel to each other which are articulated at one end about a common hinge axis 497 on the mounting flange 44 of the first frame part 41. In a central area, the two swivel levers 491, 492 are connected to one another via a cross-member 494.
  • a shaft 493 extending transversely to the pivot levers 491, 492 is rotatably articulated, on which a coupling arm 495 is rotatably attached approximately in the middle.
  • the actuator 6 is designed as a linear motor with a nut 62 which can be linearly adjusted via a spindle 61.
  • a coupling eye 63 is provided, with which the actuator 6 is hingedly connected to the coupling arm 495 about a second hinge axis 498.
  • the nut 62 is coupled to the seat 1 via a connecting element 11.
  • each position of the seating furniture is defined by a characteristic distance between the coupling eyelet 63 or the second joint axis 498 and the nut 62.
  • the actuator 6 By actuating the actuator 6, the nut 62 can be moved along the spindle 61 to the respectively desired distance from the coupling eyelet 63, in which the chair assumes the position assigned to the distance.
  • the actuator rotates in the first direction of rotation, the distance between the coupling eyelet 63 and the nut 62 is shortened, while activation in the opposite second direction of rotation increases the distance.
  • the nut 62 In the upright basic position, the nut 62 is in a central position on the spindle 61, in which it is at a distance a 1 from the coupling eyelet 63. If the actuator 6 is actuated in a first direction (direction of rotation of the spindle 61), the nut 62 moves in the direction of the coupling eyelet 63 and thereby shortens the distance between the coupling eyelet 63 and nut 62. This in turn activates the stand-up aid so that the seat 1 and the backrest 2 move into the raised position according to Fig. 2 . In this position, the nut 62 is only a distance a 0 from the coupling eyelet 23.
  • connection of the nut 62 to the seat 1 via the connecting element 11 acts as an abutment, so that a tensile force in the direction of the arrow 499 ( Fig. 7a ) acts on the coupling arm 495 in the region of the coupling eyelet 63.
  • this tensile force causes the shaft 493 to rotate clockwise until two first actuating levers 101, which are non-rotatably connected to the shaft 493, come into contact with a first stop 500 and prevent further rotation of the shaft 493 ( Fig. 7a and 7b ).
  • the stand-up aid 7 is essentially formed by two lifting rods 71 and the swivel frame 49.
  • the two lifting rods 71 are likewise articulated at the lower end to the two lateral fastening flanges 44 of the base frame 4 so as to be pivotable about a third hinge axis 72.
  • the upper ends of the lifting rods 71 are each articulated to a lateral coupling element 12 about a fourth articulation axis 73.
  • the first coupling elements 12 are laterally firmly connected to the seat 1 or an associated seat frame.
  • a tensile force in the direction of the arrow 499 causes the lever linkage 71 and the swivel frame 49 to pivot about the third hinge axis 72 or the first hinge axis 497 until the shortest distance a 0 between coupling eyelet 63 and nut 62 according to Fig. 2 is reached.
  • the seat 1 and the backrest 2 are in a raised position compared to the upright basic position according to Fig. 1 , in which raised position the seat 1 and the backrest 2 are also equally tilted forward in order to facilitate standing up or sitting down. If the actuator 6, starting from the raised position according to Fig. 2 , is actuated in the second opposite direction, the seating furniture initially assumes the upright basic position according to Fig. 1 again.
  • a further actuation of the motor 6 in the second direction causes a further displacement of the nut 62 in the sense of an increase in the distance between the nut 62 and the coupling eyelet 63, which in turn initially actuates the footrest adjustment mechanism 8, causing the footrest 3 to extend.
  • the footrest adjustment mechanism is designed, for example, in the manner of a scissor mechanism.
  • the implementation of the footrest 3 with the aid of the footrest adjustment mechanism 8 is well known to those skilled in the art and is ultimately based on the fact that the seat 1 is at least moved backwards, the footrest adjustment mechanism 8 connected to the seat 1 or the seat adjustment mechanism 91 causing the footrest 3 to extend.
  • the angle between seat 1 and backrest 2 is hardly or not at all changed when the footrest 3 is extended.
  • the backrest 2 is coupled to the seat and the seat-adjusting mechanism 91 via a backrest adjustment mechanism 92.
  • spring elements 921 are provided which initially only extend the footrest 3 and do not yet adjust the backrest 2 relative to the seat 1 when the actuator is activated from the upright basic position according to Fig. 1 into the reclined position according to Fig. 4 . Only when the footrest 3 is extended and the actuator 6 is further actuated is the backrest 2 adjusted against the force of the spring elements 921, in that the angle between the seat 1 and the backrest 2 is increased by the backrest adjustment mechanism 92. In addition, the front region of the seat 1 can be raised.
  • the backrest adjustment mechanism has a stop element 922 ( Fig. 9 ), which blocks a further rotation of the backrest 2 relative to the seat 1 between the reclined position according to Fig. 4 and the tilted position according to Fig. 5 .
  • the stop element 922 now causes the actuator 6 to exert a compressive force on the coupling arm 495 in the direction of the arrow 501 so that the shaft 493 rotates counterclockwise in Fig. 8a .
  • the tilting mechanism 10 is triggered, which comprises the first actuating lever 101 and a second actuating lever 102, which are each present on either side of the seating furniture.
  • the two first actuating levers 101 are each connected non-rotatably to the shaft 493 of the swivel frame 49 at one end.
  • the second operating levers 102 are hingedly connected, which actuating levers are in turn hingedly connected at their other end to the second frame part 42, specifically at the end facing away from the front standing rollers 48.
  • a counterclockwise rotation of the shaft 493 then causes a relative adjustment of the first frame part 41 with respect to the second frame part 42 about the transverse axis 43, the two frame parts 41, 42 forming an X ( Fig. 5 ).
  • the first frame part 41 is supported on its rear supporting feet 46 on the standing surface 5 and form the tilting axis around which the seating furniture is tilted.
  • the front standing rollers 48 of the second frame part roll on the standing surface 5 during the tilting process in the sense of a shortening of the distance between the rear (stationary) supporting feet 46 and the front standing rollers 48.
  • the footrest 3, the seat 1 and the backrest 2 are tilted backwards as a unit during the tilting process, so that the footrest 3 is raised and the headrest 21 is lowered relative to the standing surface 5.
  • a second stop 13 can be provided on the seat 1 or on the seat adjustment mechanism 91 or at another suitable point ( Fig. 6 ), which blocks the rotation of the shaft 493 until the seating furniture has reached the reclined position shown in Fig. 4 .
