Abstract

A safety system for a vehicle is disclosed. The system includes a means for pulling the steering wheel/column away from the driver in the event of a head-on collision, and an inflatable cushion which is mounted on the steering wheel. The pulling away of the steering wheel triggers the inflation of the cushion. Also disclosed is a similar safety system for the passenger side of the vehicle.

Claims

1. In an apparatus for enhancing the safety of a person in an automotive vehicle of the kind comprising a chassis having a portion deforming in a collision of a predetermined force, drive means mounted for movement relative to said chassis in response to the deformation, steering means mounted on a column extending in the direction of said person, elongate means connected to said chassis and said drive means for displacing said steering means in a direction away from said person in response to said movement, first inflatable means for providing protection between said person and said steering means in such collision, the improvement comprising:

means for inflating said inflatable means in response to the displacing of said steering means.

2. The apparatus of claim 1, wherein said means for inflating comprises inertia means moving in response to the displacement of said steering means from a first to a second position.

3. The apparatus of claim 2, wherein said means for inflating further comprises gas generating means actuated by an explosive charge, said inertia member when moving to its second position releasing firing means of said gas generating means.

4. The apparatus of claim 3, wherein said firing means comprises spring-loaded striker means separated from an ignition means cap when said inertia means is in its first position and movable to strike said detonation cap when said inertia means is in its second position.

5. The apparatus of claim 4, wherein said inertia means is mounted for movement along a path intersecting said striker means and said ignition means.

6. The apparatus of claim 5, wherein said inertia means is retained in its first position by frangible means.

7. The apparatus of claim 4, wherein said ignition means comprises detonation cap means.

8. The apparatus of claim 4, wherein said ignition means comprises electrical ignition means.

9. The apparatus of claim 1, comprising further inflatable means and said inflating means comprises means responsive to said movement of said drive means.

10. The apparatus of claim 9, wherein said inflating means comprises latch means operatively connected to said drive means by elongated means for movement from a first to a second position in response to said movement of said drive means, said latch means when in its first position retaining spring-biased striker means against movement and when in its second position releasing said striker means to move into engagement with ignition means.

11. The apparatus of claim 10, wherein said latch means is movable along a path intersecting said striker means and said ignition means.

12. The apparatus of claim 11, wherein said ignition means comprises detonating cap means.

13. The apparatus of claim 11, wherein said ignition means comprises electric ignition means.
