Detailed description the preferred embodiment

1 to 6 show a motorized ambulance chair according to the invention. It consists of a body ( 1 ) and a seat unit ( 2 ). The body ( 1 ) has the shape of a cuboid with an interior ( 16 ). It contains two spaced-apart steerable front wheels ( 12 ), a hinged upper cover ( 17 ), a battery unit ( 14 ) with one or more batteries, one from the battery unit ( 14 ) Powered motor ( 13 ) for driving the front wheels ( 12 ), two retractable support wheels ( 15 ) behind the front wheels ( 12 ) under the battery ( 14 ), a recessed coupling ( 18 ) at the lower end of the back of the body ( 1 ), one with the battery unit ( 14 ) connected headlights ( 101 ) at a central location in the front of the body ( 1 ), two with the battery unit ( 14 ) connected indicator lights ( 100 ) in the side edges of the body front and a vertical support ( 19 ) above the coupling ( 18 ) on the body rear side with a semicircular cross-section, in which a T-shaped handlebar ( 11 ) with padded side handles ( 111 ) and a control unit (not shown) mounted in height displaceable and provided with resilient detents.

The seat unit ( 2 ) contains a rectangular footrest ( 21 ) with a coupling ( 211 ) which is releasable with the coupling ( 18 ) on the body ( 1 ), a rectangular rear base ( 22 ) whose front end is hinged to the footrest ( 21 ) and at the rear end an upwardly pointing short pipe section ( 221 ), two non-steerable rear wheels ( 24 ) below the base ( 22 ) and one of a seat ( 232 ) with one of them down vertically outgoing seat column ( 231 ) hinged in the pipe section ( 221 ) is attached and an obliquely down to the base ( 22 ) extending arm ( 233 ), existing seat ( 23 ). The arm ( 233 ) consists of an upper and a lower part, over which a sleeve ( 234 ) is pushed.

For use, the wheels are preferably designed as castors ( 15 ), the handlebar ( 11 ) is adjusted to the appropriate height and the driver takes on the seat ( 232 ) Space. To operate the vehicle serve the handles ( 111 ) and the control unit.

4 to 6 show how the motorized ambulance can be folded up for storage. By disconnecting the coupling ( 211 ) of the coupling ( 18 ) first be body ( 1 ) and seat part ( 2 ) separated from each other. After that, the support wheels ( 15 ) collapsed. Then the footrest ( 21 ) against the base ( 22 ) until it is parallel with this and the sleeve ( 234 ) of the arm ( 233 ) away. Then the pin, the seat column ( 231 ) with the pipe section ( 221 ) connects away so that seat pillar ( 231 ) and base ( 22 ) can be brought into a paralell running position. Then the pin is attached again. After the seat unit ( 2 ) as in 6 is folded, the cover ( 17 ) and the seat unit ( 2 ) in the interior ( 16 ) of the body ( 1 ) stowed (see 4 ). To save even more space, the handlebar ( 11 ) are inserted.
