Abstract

A safety device for restraining and deflating an airbag. The safety device 10 is intended to be used by rescue personnel at vehicle accident scenes to prevent the risk of injury to rescue personnel and/or an accident victim from an inadvertent deployment of a vehicle'"'"'s driver'"'"'s side self-inflating restraint, commonly referred to, and referred to herein, as an airbag. The safety device 10 is securable to a conventional steering wheel 12 and provides a rigid barrier between the steering wheel 12 and a rescuer or accident victim. The safety device 10 includes a rigid, shield member 15, having a front 17 side and a back side 18. At least one cutting member 20 for rupturing the airbag upon deployment is disposed on the back side 18 of the shield member 15. A cage member 30 depends from the back side 18 of the shield member 15 and receives a first portion 32 of the steering wheel 12. The cage member 30 cooperates with a locking member 50, and is in spaced relation from the locking member 50 which receives a second portion of the steering wheel 12, in order to fix the safety device 10 to the steering wheel 12 in a positive locking manner.

Claims

1. A safety device for mounting on an automobile steering wheel for preventing injury caused by inadvertent deployment of an airbag, said safety device comprising:

a rigid, shield member, having a front side and a back side;

at least one cutting member carried by said back side of said shield member;

a cage member defining a steering wheel receptor depending from said back side of said shield member and receives a first portion of the steering wheel;

at least one brace member disposed on the back side of the shield member; and

a locking member carried by said shield member for receiving a second portion of the steering wheel and for fixing said safety device to the steering wheel in a positive locking manner, wherein said locking member cooperates with said cage member and is in spaced relation from said cage member.

2. The safety device of claim 1 wherein said shield member is sized to substantially cover a conventional steering wheel.

3. The safety device of claim 1 wherein said shield member is substantially planar.

4. The safety device of claim 1 wherein said safety device comprises a plurality of said cutting members carried by said back side of said shield member.

5. The safety device of claim 1 wherein said cutting members have a substantially triangular silhouette.

6. The safety device of claim 1 wherein said cage member is defined by an elongated cross bar supported in spaced relation from said shield member by leg members depending from said shield member.

7. The safety device of claim 6 wherein said leg members are substantially perpendicular to said shield member.

8. The safety device of claim 6 wherein said elongated cross bar, said leg members, and said brace member are constructed of square tubing and said cross bar is secured to said leg members as by welding.

9. The safety device of claim 6 wherein said cross bar, said leg members and said brace member are integral.

10. The safety device of claim 6 wherein said cross bar, said leg members and said brace member are cylindrical in cross section.

11. The safety device of claim 1 wherein said locking member is defined by at least two extensions that depend from said back side of said shield member, wherein said extensions are adapted to receive a securement member, and further wherein said extensions are disposed in close proximity to one another and are spaced apart so as to receive the second portion of the steering wheel there between, said securement member being adapted for locking the second portion of the steering wheel in a positive locking manner within the space defined by the extensions.

12. The safety device of claim 11 wherein said securement member is a bolt that is secured with a threaded nut.

13. A safety device for mounting on an automobile steering wheel for preventing injury caused by inadvertent deployment of an airbag, said safety device comprising:

a rigid, shield member, having a front side and a back side;

a plurality of cutting members carried by said back side of said shield member;

a cage member defining a steering wheel receptor depending from said back side of said shield member and receives a first portion of the steering wheel, wherein said cage member is defined by an elongated cross bar supported in spaced relation from said shield member by leg members depending from said shield member;

at least a pair of brace members disposed in spaced relation to one another on the back side of the shield member; and

a locking member carried by said shield member for receiving a second portion of the steering wheel and for fixing said safety device to the steering wheel in a positive locking manner, wherein said locking member cooperates with said cage member and is in spaced relation from said cage member.

14. The safety device of claim 13 wherein said shield member is substantially planar.

15. The safety device of claim 13 wherein said leg members are substantially perpendicular to said shield member.

16. The safety device of claim 13 wherein said elongated cross bar, said leg members, and said brace members are constructed of square tubing and said cross bar is secured to said leg members as by welding.

17. The safety device of claim 13 wherein said cross bar, said leg members and said brace members are integral.

18. The safety device of claim 13 wherein said cross bar, said leg members and said brace members are cylindrical in cross section.

19. The safety device of claim 13 wherein said locking member is defined by at least two extensions that depend from said back side of said shield member, wherein said extensions are adapted to receive a securement member, and further wherein said extensions are disposed in close proximity to one another and are spaced apart so as to receive the second portion of the steering wheel there between, said securement member being adapted for locking the second portion of the steering wheel in a positive locking manner within the space defined by the extensions.

20. The safety device of claim 19 wherein said securement member is a bolt that is secured with a threaded nut.
