a bus, an ambulance, an aircraft or a watercraft.

While moving a vehicle that has a wheelchair transported, it is necessary to fix the wheelchair in one position in the same. So far, especially in the device according to DE-OS 26 41 712, a wheelchair in a certain position in a vehicle by complementary hooks and crossbars at the front and rear of the wheelchair and corresponding ones Positions of the vehicle attached. A lock was added to keep these engaged Formations provided with each other. Guides are also provided to engage the parts concerned when the wheelchair is rolled into position in the vehicle. Nonetheless, this is The device is still relatively expensive and it is therefore the object of the invention to provide a simplification of the same.

The object is achieved according to the invention in that the securing means are laterally spaced from one another hook means disposed on the floor or wheelchair adjacent one end thereof; that Cross bars are provided on the wheelchair adjacent to one end thereof or on the floor, the cross bars fit into the hook means when the wheelchair is in the predetermined position to substantially prevent relative vertical movement between the wheelchair and the floor; that complementary locking elements on the floor and the wheelchair adjacent the other end thereof for disengagement of the hook means and to prevent the crossbars when they are connected to the wheelchair in the predetermined position are and also essentially vertical relative movements between the floor and the wheelchair on the other Prevent the end, with guide elements on the

chair and on the floor are provided to the locking elements and the hooks as well as the cross bars in mutual Intervention in bringing the wheelchair into the predetermined position on the floor.

By using complementary elements that both hold the wheelchair in place, the To prevent opening of the hook means and cross bar means, and also relative vertical movements between Floor and wheelchair prevent the need for additional, second complementary fasteners be bypassed on the floor and on the wheelchair, adjacent to its other end - this means a construction simplification compared to the prior art.

The complementary closing elements can have a loop or generally a "U" -shaped part, that extends downward from part of the wheelchair to provide an opening with which a clasp can come into engagement to keep the latter in the mouth of a lock.

The invention thus relates to a wheelchair that engages with one another in a vehicle Oncoming hooks and crossbars must be secured to the floor of the vehicle and one end of the wheelchair can, with closing elements applied to the other end of the wheelchair and the floor of this end of the wheelchair and hold the hooks and the cross bars in engagement with each other. The locking element, hook and crossbar, are engaged when the chair is rolled into the vehicle.

Further features and advantages of the invention emerge from the claims and from the following description, in which an embodiment is explained with reference to the drawing consisting of four figures. She shows:

Fig. 1 is a side view of a vehicle in which a wheelchair is arranged;

FIG. 2 is a view in the direction of arrow 2 in FIG. 1; FIG.

Fig. 3 is a perspective view of the in

Engaging coming lock elements, such as shown in Figure 2; and

4 is a perspective view of a hook of the vehicle.

In Fig. 1 of the drawing, a vehicle 10 is shown in which a wheelchair 11 is recorded. This vehicle 10 has a side door 12 and a rear door 13 which are formed in two parts and includes a lower portion that can be pivoted down to a ramp form on which the wheelchair can be moved into the vehicle.

The wheelchair has a tubular frame 14 that supports forms for the occupant, as well as for a pair of pneumatic tires 15 with a relatively large diameter, around an axis (16) at the rear end of the wheelchair are rotatable. At the front of the wheelchair, the frame has to be pivoted by castors a couple of wheels 17 with a relatively small diameter. A cross bar 18 extends across the wheelchair at the rear end thereof, and a tubular member extends from the cross bar 18 to an im

essentially horizontally supported plate 20 attached to the apex of a generally "V" -shaped lower frame is partly welded, the ends of which are connected to the main frame of the wheelchair.

The bottom of the vehicle 10 is _r, equipped with arranged in laterally spaced hooks 22, whose mouth openings facing the rear end of the vehicle located on a raised part _t of the are situated between the wheels of the wheelchair when the latter is in position, arranged . These hooks engage the crossbar 18 when the wheelchair is in the desired position in the vehicle and prevent relative movement in the vertical direction between the end of the wheelchair and the vehicle.

On the floor of the vehicle at the front end of the wheelchair is a lock 23 which details is shown in Figs. This lock points a base plate 24 which is attached to the vehicle floor by means of fasteners, which through Openings 25 go and which has a lock body 26, whose mouth opening 27 points to the rear »A clasp 28 enters with the mouth opening of the lock together and can come into engagement with a loop which is underneath the plate 20 of the wheelchair is attached to hold the loop 29 in the mouth of the lock when the clasp 28 extends through the loop 29. The mouth opening is conical to allow the clasp 29 to be inserted into it easier when the wheelchair is moved into the vehicle.

The lock 23 is of the self-opening type used on car doors,

and thus provides a high resistance to vertical and longitudinal movements of the front part of the wheelchair in the vehicle when the locking element of the wheelchair in the form of the loop 29 with the clasp has come into action. The crossbar at the end of the wheelchair becomes just as good as this attachment held in tight engagement with the hook 22, creating a high resistance of the entire wheelchair against Relative movements within the vehicle is guaranteed. This becomes without the use of any reached additional connectors on the wheelchair and the vehicle.

To allow separation of the wheelchair from the vehicle, the clasp 28 of the lock is by means of a flexible cable arrangement 30 of conventional design apparently, which by a button 31, which is on located on the dashboard of the vehicle.

There can be additional guide means to those that are formed by the conical jaws of the lock 23, be provided to bring the loop 29 of the wheelchair into engagement with the lock. Farther may have means of properly engaging the crossbar at the rear of the wheelchair the hook 22 of the vehicle may be provided.

The hooks 22 can be designed and arranged so that they the force with which the rear wheels of the The wheelchair engages the floor of the vehicle, reinforce it. This supports the in-position Keeping the wheelchair in the vehicle.
