- 3 ICE PROTECTION FOR VEHICLE DOOR LOCKS

The invention relates to an anti-icing device for vehicle door locks .

I * / At outside temperatures around or below freezing point there is a risk that vehicle door locks will ice up, so that the associated key is no longer inserted or at least can no longer be rotated. To fix it this problem, various freezing point lowering liquids or sprays are known, their Effect is limited, however. In addition, electrically heated door locks are known, but represents this is a complex and expensive solution,

Λ The invention is therefore based on the object of a to create simple, inexpensive anti-icing protection that can be used for any type of vehicle.

The solution according to the invention consists in an anti-icing protection for. Vehicle door locks in the shape of an arched, a cap formed as a sealing lip, having a circumferential edge with a number of inside permanent magnets attached to the cap.

The open side of the cap becomes dome-shaped a door lock or a door handle with an integrated door lock and then sticks with the help of the permanent magnets on the vehicle door. In this way moisture is kept away from the door lock and it results at the same time a certain protection against the cold, so that. icing is ruled out under almost all conditions is.

The cap is preferably made of heat insulating

Material * The permanent magnets are on the back the sealing lip, which consists in particular of rubber / so that direct contact between the Permanent magnets and the vehicle door, which can damage the paintwork could not lead. The cap can also In addition to a waterproof outer layer, there is also a relatively thick inner foam insulating layer have, and the permanent magnets can in this Iso-1 ifirschich-fc in the area of the Russian side äeir DiGhtÜPPe a— be bedded.

The anti-icing device can have a circular shape to cover door locks or an elliptical shape to cover door handles with an integrated door lock.

Preferably four permanent magnets evenly distributed around the circumference are provided. These offer the possibility to fold the anti-icing protection up to the open side, if it is not needed. In this position it is held together by opposing permanent magnets so that a space-saving shape results.

Figure 4 is a bottom view of Figure

Figure 1 shows ein.Zylinder door lock 10, which is in a only indicated vehicle door 12 is mounted. about the door lock 10 is from the one at the top in FIG A cap 14 is placed on the outside of the door. The cap 14 consists essentially of a water-impermeable outer layer 16, for example a suitable one Plastic, and an inner insulating layer 18 for thermal insulation, for example made of a foam. the Cap is at her open. Edge bounded by a circumferential sealing lip 20, which is against the outer surface the vehicle door. On the back of the sealing lip 18 permanent magnets are in the foam of the insulating layer 22 embedded die.die cap 14 on the vehicle door 12 hold. According to Figure 2, there are four permanent magnets 22 provided at regular angular intervals.

25 In many vehicles, the door lock is integrated into a handle to open and close the door. FIG. 3 shows a door lock 30 which is inserted into a handle 32, which in turn is attached to a vehicle door 34 is attached. In. this case is the inventive Anti-icing protection designed as an elongated cap 36 with an essentially elliptical outline. The cap 36 consists, in turn, of an outer layer 38 and an insulating layer 40, which extends to the vehicle door through a circumferential Sealing lip 42 are complete .. On the back of the sealing lip 42 are located within the Material of the insulating layer 40 some permanent magnets 44. According to Figure 4, four permanent magnets are symmetrical Arrangement provided.
