  • Chassis frame with a central support plate to which all undercarriage elements are connected is therefore characteristic of the invention.
  • a further development of the invention provides that the bearing bracket for storage that can be swiveled around vertical axes of the front castors spaced from the central one Carrier plate on support arms firmly connected to this are arranged.
  • the support arms with the bearing bracket diverging from each other the central carrier plate in the direction of travel.
  • brackets for articulation Spring element can expediently be console plates act that are essentially rectangular extend from the carrier plate.
  • brackets for articulating a spring element on the one from the storage console for those around vertical axes pivotal positioning of the front castors Extend the side from the central carrier plate.
  • the carrier plate with an over their entire width-reaching profile tube in particular equip a rectangular tube, at the ends of each one of these consoles is connected.
  • chassis frame is a welded construction.
  • the chassis frame can also be detachable Recording for a seat and also with one in the access area operating console of a user be equipped.
  • the electric wheelchair illustrated in FIGS. 1 and 2 10 has a compact chassis frame 11, in the manner to be described below two rear drive wheels 12 and two front castors 13 are stored. On the chassis frame is in a seat 14 with no further interest here a backrest 15 is added and next to the seat 14, in the grip area of the user of the wheelchair 10 a control console that is also of no interest here 16. Finally, the front end is one Seat frame 17 connected to a height-adjustable footrest 18.
  • Chassis frame 11 has a central support plate 20, to the diverging forward in the direction of travel Support arms 21, 21 'are welded.
  • a bearing bracket 22 with bearing mounts 23, 23 'for the pivotable storage about vertical axes the front castors 13 arranged.
  • the two diverging support arms 21, 21 ' are through the continuously formed bearing bracket 22nd braced.
  • Support arms 21, 21 ' are with the support plate 20 on both Sides projecting journal 24, 24 'firmly connected and over the support arms 21, 21 'with the bearing bracket 22 for the front bearing, which can be pivoted about vertical axes Swivel castors 13 extend on both sides to the central one Carrier plate 20 connected console plates 25, 25 'continues, also with the foreheads one over the entire Width of the central support plate 20 reaching and ver with this firmly connected profile tube 26 are welded.
  • Any gear motor is supported by a spring element 34, 34 ', on the one hand on the upper side of the respective gear housing and on the other hand from the central carrier plate 20 of the chassis frame 11 according to that of the front Swivel castors 13 pioneering side extending console plates 25, 25 'are articulated.
  • the wheelchair 10 is also with a battery box 35 equipped in which suitable batteries 36 for Supply of the electric motors 33, 33 'of the drive wheels 12 acting geared motors 31, 31 'added are.
  • the battery box 35 is self-supporting and in a way of no interest to the central one Carrier plate 20 connected.
  • the battery box As shown in FIG. 2 in particular, 35 extends between through the rear drive wheels 12.
  • the chassis frame 11 of the wheelchair 10 according to the invention is characterized by its compact and within the Wheelchair space-saving design and large Stiffness.
  • chassis frame 11 Characteristic of the chassis frame 11 is the central one Carrier plate 12 spaced from the front Swivel casters 13 extend across the direction of travel in the wheelchair and on the the storage of the front castors 13 serving bracket 22 with the bearing mounts 23, 23 'connected via the support arms 21, 21' and the Swing 30, 30 'to guide the rear drive wheels 12 are articulated.
  • the compact design of the chassis frame 11 with the vertically running support plate 20 enables the easy accommodation of one to the Carrier plate connected battery box, the under the seat 14 and between the rear drive wheels 12 is recorded.
