Definitions

  • the invention relates to an adjustment device for a seat or a couch, in particular for a bed, according to the generic features of the claim 1.
  • An adjustment device for tires is known (DE-GM-88 06 094.2; EP 372 032), which strives for such a device compared to previously known adjusting devices to be more compact and without laying cables or wiring easier to design to make assembly easier. It is proposed to arrange known linear drives in a box-shaped housing, where adjusting spindles with screwed adjusting nuts in guides of the housing are stored and for adjusting the housing longitudinal and / or transverse stiffening ribs are provided.
  • the electric motor is via a worm gear connected to the threaded spindle with adjusting nuts and the adjusting nut lies against an independent angle lever, the arm lengths of the length and determine the height of the housing.
  • the bell crank doesn't just take one considerable installation space, but builds the same height in the start and end positions, so that the overall height and length of the housing are undesirably large.
  • the housing is also set up to always drive two grate sections, so that a solution for a grate section is eliminated from the start.
  • the object of the invention is to make the adjustment drive even more compact as well as with the property of a single grate drive.
  • the object is achieved in that the electric motor via a gearbox to a rotating eccentric in a vertical plane located round disc with external teeth that the Washer is fixed to the outer frame so that the washer has external teeth engages in a larger ring with internal teeth, on the ring, the rod for transmitting the adjusting force to a grate section is attached.
  • This not only makes the adjustment drive compact, it also makes it the property also arises, the adjustment drive separately for only one of the grate sections to use. The further compactness arises from the resulting flat disc design.
  • the power transmission only takes place in the stroke direction of the grate section instead. Multiple grate sections can be used for different widths such small adjustment drives are used.
  • the electric motor parallel to Outer frame is connected to the eccentric by a bevel gear. This also saves space and increases the compactness.
  • Another economical design of the first stage of the drive also results in that the electric motor in the manner of a wiper motor for motor vehicles is executed.
  • the fixed support for the transmission of the torque is after a further training the invention in that the disc to the outer frame flexible on the outer frame using a rod-shaped torque arm is held.
  • the flexibility can now be designed such that the torque arm an elongated hole for the fastening element at the fastening point on the outer frame having.
  • the ring with the external toothing on which the torque arm is screwed on, the eccentric movement can be applied to the torque arm via the slot transmitted, which is free to absorb the eccentric movement.
  • the eccentric in the round disc by means of a Rolling or plain bearing is rotatably mounted.
  • the eccentric movement can be done without great resistance to be transferred.
  • the speed to be transmitted from the electric motor to the respective grate section which requires a significant slowdown, is accomplished that the reduction ratio from the reduction of the electric motor / Worm gear and external toothing / internal toothing is formed, the Internal teeth the larger diameter for the smaller external teeth having.
  • the drive is of electric motor and reduction gear, as a unit one or is assigned to two grate sections. This allows one or more grate sections can be equipped with single or double drives.
  • the arrangement can also be varied by for a narrow seat or the drives are mirrored on the inside of the outer frame are attached.
  • the adjustment device is for a seat 1 (e.g. an automobile seat) or a couch 1 primarily but for a bed 1, e.g. a hospital bed, provided and created (Figs. 1 and 2).
  • a seat 1 e.g. an automobile seat
  • a couch 1 primarily but for a bed 1, e.g. a hospital bed, provided and created (Figs. 1 and 2).
  • head and / or back grate sections 3 and leg grate sections 4 are arranged on an outer frame 2 with an inner side 2a and an opposite Inside 2b.
  • the head grate sections 3 and back grate sections 3 are by means of joints 5 and also the leg grate sections 4 connected by means of joints 5 and form an inner frame 6.
  • On the outer frame 2 is the inner frame 6 with its grate sections 3 and 4, which on both sides by means of cross bars Form composite, pivoted.
  • Rods 7 are fastened to the grate sections 3, 4 by means of a linkage 7a, which are connected at each end to a drive 8.
  • the drives 8 form together with an electric motor 10 and a reduction gear 11 a unit 9 which can be used in variations.
  • the electric motor 10 is connected to one via the gear 11a as a reduction gear 11 rotatably mounted eccentric 12 in the vertical plane to a round disk 13 fixed with external teeth 13a, between the gear 11a and a Base plate 11c spacers 11d determine the distance and this Fix screws 11e.
  • the reduction gear 11 can at this point consist of a standard worm gear 11b exist.
  • the disc 13 engages with the external toothing 13a in a ring 14 with a larger internal toothing 14a in diameter.
  • On the ring 14 is the rod 7 for transmitting the adjusting force to a grate section 3 or 4 attached.
  • the electric motor lying parallel to the outer frame 2 according to FIGS. 3A and 3B 10 is connected to the eccentric 12 via an angular drive 15.
  • the electric motor 10 can also be in the manner of a wiper motor for motor vehicles be executed. It is a DC motor with an input voltage of 24 volts or 42 volts.
  • the electric motor 10 with the angular drive 15 is directly on the Base plate 11c attached via spacers 11d and screws 11e.
  • Both the disc 13 and the ring 14 are flat and of exactly the same thickness slidably guided between a base plate 21 and the base plate 11c
  • the eccentric 12 is with coaxial shafts in the base plate 11c and in the Base plate 21 guided in rotation.
  • the eccentricity is between the shafts 12a, which is rotatably supported by means of a roller or slide bearing 19, which consists of a Needle bearings can exist.
  • the disc 13 is to the outer frame 2 by means of a rod-shaped torque arm 16 in an elongated hole 16a at a fastening point 17 for a fastening element 18 resiliently supported in the direction of the elongated hole 16a.
  • the reduction ratio from the reduction of the electric motor 10 and the standard worm gear 11b on the one hand and the external toothing 13a with the internal toothing 14a on the other hand is based on the larger diameter of the internal toothing 14a compared to the smaller diameter of the external toothing 13a.
  • the drive 8 is (Fig. 5 and 6), consisting of the electric motor 10 and the reduction gear 11 formed as a unit 9 and each a grate section 3 and 4th assigned.
  • drives 8, 8 are mirror images each arranged on the inside 2a of the outer frame 2.
  • the drives 8 mirror image on the two inner sides 2a and 2b of the outer frame 2 attached.
