Abstract

For a motor vehicle with at least one passenger seat which has attachment devices for a child'"'"'s safety seat that can be attached to it and at least one air bag in the region of the passenger seat, the invention proposes that at least one attachment device for the child'"'"'s safety seat be provided with a sensor for deactivating the air bag which reacts to the attachment of the child'"'"'s safety seat. This assures that during the transportation of the child in the child'"'"'s safety seat, the air bag in front of the child'"'"'s safety seat is deactivated.

Claims

1. A motor vehicle with at least one passenger seat which has seat belt-type attachment devices for a child'"'"'s safety seat to be secured thereon, the child safety seat having a supporting structure with fixably connected securing devices for connection to the seat belt-type attachment device, and the motor vehicle having at least one air bag in the region of the passenger seat, wherein at least one seat belt-type attachment device for the, child'"'"'s safety seat is provided with a sensor, which reacts to the attachment of the child'"'"'s safety seat, for deactivating the air bag.

2. A motor vehicle according to claim 1 wherein the sensor is constructed as a pulse generator to manufacture a signal acting on an air bag control to deactivate the air bag.

3. A motor vehicle according to claim 1 wherein the signal of the sensor deactivating the air bag is used to determine the connection of the child'"'"'s safety seat to the passenger seat.

4. A motor vehicle according to claim 1 wherein the seat belt-type attachment device is constructed to be a female receptacle click-in securing device.

5. A motor vehicle according to claim 1 wherein the seat belt-type attachment devices are arranged on both sides of the seat cushion of the passenger seat.

6. A motor vehicle according to claim 1 wherein the seat belt-type attachment devices are arranged in the area of a neck between a back rest of the passenger seat and a seat cushion of the passenger seat.

7. A motor vehicle according to claim 1 wherein the attachment devices are arranged on both sides of the passenger seat in the region of the back rest supports.

8. A motor vehicle according to claim 1 wherein the seat belt-type attachment devices also are utilized to provide seat belt lock receptacles for safety belts which are provided for the passenger seat when the child'"'"'s safety seat is not being used.

9. A motor vehicle according to claim 1 wherein the seat belt-type attachment devices are connected to a supporting structure of the passenger seat.

10. A motor vehicle according to claim 1 wherein the seat belt-type attachment devices are connected to a chassis of the motor vehicle.

11. A motor vehicle according to claim 1 wherein the child'"'"'s safety seat supporting structure has a rigid seat shell which has cushioning and belts for securing the child into a seating bowl fitted within the shell.

12. A motor vehicle according to claim 11 wherein the child'"'"'s safety seat securing devices are arranged on an end of the supporting structure facing away from a back rest of the child'"'"'s safety seat.

13. A motor vehicle according to claim, 11 wherein the child'"'"'s safety seat securing devices are additionally arranged on an end of the supporting structure facing away from a back rest of the child'"'"'s safety seat.

14. A motor vehicle according to claim 11 wherein the child'"'"'s safety seat supporting structure is constructed to be a supporting frame.

15. A motor vehicle according to claim 11 wherein the child'"'"'s safety seat securing devices are constructed to be in the form of plug-in tongues for a safety belt lock receptacle.

16. A motor vehicle according to claim 11 wherein the child'"'"'s safety seat supporting structure has a support bracket securely fixed to the same which is supported against a back rest of the passenger seat when the child'"'"'s safety seat is secured to the passenger seat.

17. A motor vehicle according to claim 16 wherein the child'"'"'s safety seat securing devices of the supporting structure receive catching devices provided with rollers, and the safety seat securing devices of the supporting structure have a catching device which receives a hand grip.
