The invention relates to a device for assistance the retraction and fixation of a cot having a collapsible chassis in a motor vehicle provided rails *

Carriages have an approximately 60 cm high chassis, the when driving the cot into a vehicle equipped with the appropriate rails, in particular an ambulance, must be folded.

This folding in of the ferry frame takes place in practice in such a way that the cot is driven against a cross member, the loading side in the lower area of the respective Vehicle is attached. At the moment of starting, the front part of the cot is already in the Vehicle, and the pressure exerted on the chassis by the approach to the crossbeam leads to its Legs can be folded down and the cot can be fully pushed into the vehicle, where appropriate Fixation of the stretcher, which is now in the folded state, is carried out.

It is not possible to attach a cross member that serves as a drive-in aid to all vehicles, and in particular to Passenger cars difficult because no disruptive parts can be attached below the vehicle floor. Used if you use the bumper of a passenger vehicle instead of an additional cross member, this leads in particular then, if this bumper is made of plastic, disruptive damage.

The object of the invention is to create a simply designed drive-in aid of the type specified at the beginning,

which on the one hand prevents damage to the respective vehicle And on the other hand it contributes to a particularly secure fixation of the cot in the vehicle.

\ This objective is according to the invention substantially

thereby at least at the loading end of the running rails a starting plate is pivotably mounted, which extends obliquely downwards in the pivoted-out position and bears against an external vehicle part and that at least one in the area of the free end of the starting plate Locking element is provided, which is in the pivoted, approximately vertical position of the starting plate with the cot can be locked.

The locking preferably engages over an end cross member the cot from above, which, in cooperation with the rear rollers of the folded chassis, results in immediate are located adjacent to the raised start-up plate, results in a particularly secure stretcher fixation that is achieved with minimal effort, since the approach plate is used twice.

The cot is preferably also held separately in its front area in the usual way.

Since the starting plate is preferably supported in its swiveled-out position on the bumper of the vehicle and in the An elastic protective covering can be provided in the support area, any impact damage is avoided.

Further advantageous embodiments of the invention are specified in subclaims.

The invention is described below with reference to Drawing explained in more detail; in the drawing shows:

Such a stretcher 6 is pushed so far into these rails that it is now necessary to fold in the chassis 9, which is seen ^{with rollers 8 vel Wu.}

To such an automatic retraction of the chassis without damage to the vehicle and in particular also without damage To enable a bumper 4 made of plastic, for example, a starting plate 2 is provided, which is pivotably articulated on the lower edge of the running rails 1 via hinges 3.

If the cot or the chassis 9 of the cot 6 hits this starting plate 2, the legs fold the chassis upwards, and the process of pushing it in

the now folded cot 6 in the vehicle can be completed- The rollers 8 of the cot arrive while doing this in the rails 1.

Fig. 2 shows the articulation of the starting plate 2 on the lower edge of the rails 1 via hinges 3 and the support this starting plate 2 in the pivoted position on the bumper 4.

In the area of the approach plate 2 that comes into contact with the bumper 4, a protective element, e.g. made of elastic material.

At the free end of the starting plate 2, a stiffening cross member 10 is provided, which is preferably from one to one Hollow body curved end portion of the starting plate is formed. This transverse reinforcement has a recess in the middle, in which a locking element 5 is attached in the form of a bolt. This bolt is conveniently in Locking direction biased by spring force.

3 shows the state with the cot retracted and the approach plate 2 pivoted up.

In this position, the locking bolt 5 engages over a transverse strut 7 of the cot 6 and the rollers 8 from above of the folded-in chassis 9 are located immediately adjacent to the starting plate 2. In this way, a flawless and secure fixation of the cot to the rear guaranteed. To the front is the cot in the front area held.

Since the Anfahrblecb 2 is dimensioned in its length so that on the one hand it ensures effective protection of the vehicle and on the other hand an attachment of the lock

in such a way that this lock enables an end cross member the cot can reach over from above, becomes a very simple and yet effective in its overall structure and especially with regard to the cot lock, the overall arrangement is stable.
