Problems solved by technology
[0003] Difficulties arise, however, if this known adjustment drive is used to adjust the kinematics of the bed, in particular the head part of a hospital bed.
The space available for the mechanism and for the drive head part is very limited, so that due to the space available it is not possible to use known adjustment drives with a relatively long construction
[0004] In order to avoid space problems in adjusting the head section relatively expensive short construction drivers have to be used

Embodiment Construction
[0039] Reference manual figure 1 with figure 2 , The known adjustment drive for adjusting the components of sitting and lying furniture includes: an electric drive motor 1; a rotatably mounted threaded spindle 2 driven by the drive motor 1; an adjusting nut 3, which is carried on the threaded spindle 2 and It is guided non-rotatably in the guide tube 4 and can be driven in the axial direction of the guide tube 4 by the rotation of the threaded spindle 2. A lifting pipe 5 is also provided, which is connected to the adjusting nut 3. A first pivotal connection device 6 in the form of a fork is provided at the free end of the lifting pipe 5, and the first pivotal connection device 6 can pass through the A hinge connector 7 is pivotally connected to the pivot fork 8 of the pivot shaft 9, such as from Figure 4 As can be seen.
[0040] In addition, a second pivoting connection device 10 in the form of a fork head is provided at the motor end of the adjustment drive. The second pivotin...

The invention relates to a drive for adjusting parts of seating and lying furniture, wherein a first furniture component is mounted in a movable manner relative to a second furniture component, comprising at least one spindle (2) which can be rotated by an electric drive motor (1), an adjusting nut (3) which sits on the spindle (2) and which is guided in a guide tube (4) in a rotationally fixed manner and can be driven by rotating the spindle (2) in the axial direction of the guide tube (4), a lifting tube (5) which is operatively connected to the adjusting nut (3), a first hinge device (6) which is arranged on the free end of the lifting tube (5) and which can be hinged to the first furniture component via a first hinge connection (7), and a second hinge device (10) which is provided on the opposite end of the adjusting drive and which can be secured to a stationary frame part (12) or to a second furniture component via a second hinge connection (11). Such a drive should also be usable even when only limited space is available. This is achieved in that an elongation element (13; 14) is provided on at least one of the two hinge devices (6; 10), said elongation element being rigidlyconnected to said hinge device, a respective joint half (15; 16) of the joint connection (7; 11) is arranged on the elongation element (13; 14), and the joint half (15; 16) sitting on the respectiveelongation element (13; 14) is offset in the direction of the central section (17) of the guide tube (4).
Description
Technical field [0001] The present invention relates to a driver for adjusting parts of sitting and lying furniture, wherein a first furniture component is movably installed relative to a second furniture component, and the driver includes: at least one spindle that can be rotated by an electric drive motor; adjustment A nut, which is carried on the main shaft and is non-rotatably guided in the guide tube and can be driven in the axial direction of the guide tube by the rotation of the main shaft; a lifting tube operatively connected to the adjustment nut; a first pivot A connecting device, which is arranged at the free end of the lifting pipe and can be pivotally connected to the first furniture member through a first hinge connector; a second pivotal connecting device, which is arranged at the opposite end of the adjustment drive and can be connected by a second hinge The connector is fixed to the stationary frame part or to the second furniture component.
