Abstract

A protection system for a competition vehicle for a competition vehicle driver has shoulder belt parts provided with one shoulder air bag respectively which can be inflated within fractions of seconds and can be emptied again in an energy consuming manner. In the inflated condition, the shoulder air bags are supported on the driver'"'"'s shoulder regions and support a protective helmet from below against a lateral tilting.

Claims

1. Protection system for a driver of a competition vehicle having a safety belt arrangement which, relative to the driving direction of the competition vehicle, is anchored firmly to the vehicle at a distance behind a seat position of the driver and which has two shoulder belt parts which, in the worn condition, extend in the manner of suspenders along shoulder regions at both sides of a driver'"'"'s head equipped with a protective helmet,

wherein the shoulder belt parts are equipped with at least one shoulder air bag respectively which, in fractions of seconds, can be inflated and can be emptied again in an energy-consuming manner, each shoulder air bag having an oblong shape in the inflated condition with a maximal diameter which is approximately equal to a distance between a lower edge of the protective helmet and a corresponding shoulder region of the driver so that it supports the protective helmet against a lateral tilting.

2. Protection system according to claim 1, wherein each shoulder air bag is placed on the respective shoulder belt part by means of a holding device.

3. Protective system according to claim 1, wherein each shoulder air bag flanks the driver'"'"'s neck below the protective helmet in its inflated protective position such that a tilting of the protective helmet toward the side, the front or the rear is prevented.

4. Protection system according to claim 1, wherein the safety belt arrangement has a belt force limiting device which is firmly linked to the vehicle and which is functionally combined with an air bag installed in a steering wheel of the competition vehicle.

5. Protection system according to claim 1, wherein one gas generator respectively is provided for each shoulder air bag and is placed on the corresponding shoulder belt part.

6. Protection system according to claim 2, wherein each shoulder air bag flanks the driver'"'"'s neck below the protective helmet in its inflated protective position such that a tilting of the protective helmet toward the side, the front or the rear is prevented.

7. Protection system according to claim 3, wherein the safety belt arrangement has a belt force limiting device which is firmly linked to the vehicle and which is functionally combined with an air bag installed in a steering wheel of the competition vehicle.

8. Protection system according to claim 3, wherein the safety belt arrangement has a belt force limiting device which is firmly linked to the vehicle and which is functionally combined with an air bag installed in a steering wheel of the competition vehicle.

9. Protection system according to claim 6, wherein the safety belt arrangement has a belt force limiting device which is firmly linked to the vehicle and which is functionally combined with an air bag installed in a steering wheel of the competition vehicle.

10. Protection system according to claim 2, wherein one gas generator respectively is provided for each shoulder air bag and is placed on the corresponding shoulder belt part.

11. Protection system according to claim 3, wherein one gas generator respectively is provided for each shoulder air bag and is placed on the corresponding shoulder belt part.

12. Protection system according to claim 4, wherein one gas generator respectively is provided for each shoulder air bag and is placed on the corresponding shoulder belt part.

13. Protection system according to claim 6, wherein one gas generator respectively is provided for each shoulder air bag and is placed on the corresponding shoulder belt part.

14. A motor vehicle passenger protection system comprising:

a helmet,

a safety belt harness including shoulder straps,

and shoulder air bags arranged to have an expanded maximal dimension approximately equal to a distance between an abutment section on the helmet and a shoulder region of the passenger to thereby support the helmet against lateral tilting.

15. A protection system according to claim 14, comprising a shoulder air bag actuation system operably coupled to a vehicle steering wheel air bag actuation system.
