Abstract

A sensor mounting bracket for attachment to a vehicle including a mast configured to support a sensor at a first end, a base pivotably connected to the mast at a second end, a shock absorber attached between the mast and the base, wherein the base is attached to a vehicle and the shock absorber predisposes the mast to either a deployed position or a stowed position.

Claims

1. A sensor mounting bracket for attachment to a vehicle comprising:

a mast configured to support a sensor at a first end;

a base, pivotably connected to the mast at a second end;

a shock absorber, coupled between the mast and the base;

wherein, the base is attachable to a vehicle and the shock absorber predisposes the mast to either a deployed position or a stowed position.

2. The sensor mounting bracket of claim 1, further comprising a channel disposed between the mast and the base wherein the channel is attached to the base at a pivot point and the shock absorber is attached to the mast at one end and the channel at its other end.

3. The sensor mounting bracket of claim 2, further comprising a breakaway connection wherein the breakaway connection comprises fasteners connecting the base to the channel, wherein the fasteners are comprised of material which is weaker than material forming the base and channel.

4. The sensor mounting bracket of claim 3, wherein the mast can rotate about the pivot point when the breakaway connection is disengaged from the base or channel.

5. The sensor mounting bracket of claim 4, wherein the mast pivots from the deployed position to the stowed position if impacted while the vehicle or mast is traveling in a forward direction.

6. The sensor mounting bracket of claim 5, wherein the mast pivots from the deployed position to a recoverable position if impacted while the vehicle or mast is traveling in a rearward direction and the impact disengages the breakaway connection fastener from the base or channel.

7. The sensor mounting bracket of claim 6 further comprising a bumper disposed within the base wherein the bumper cooperates with the mast when in the stowed position.

8. A vehicle sensor mounting assembly comprising:

a mast adapted to support a sensor at one end;

a base adapted to attach to a vehicle,

a channel disposed within the base and connected to the base at a pivot point wherein the channel is pivotably attached to the mast at a second end;

a shock absorber connected to the mast at one end and the channel at the other end;

wherein the mast can be positioned in either a deployed position or stowed position and the shock absorber predisposes the mast to one of those positions.

9. The sensor mounting assembly of claim 8, comprising a breakaway connection wherein the breakaway connection comprises fasteners connecting the base to the channel, wherein the fasteners are comprised of material which is weaker than material forming the base and channel.

10. The sensor mounting assembly of claim 9, wherein the mast can rotate about the pivot point when the breakaway connection is disengaged from the base or channel.

11. The sensor mounting assembly of claim 10, wherein the mast pivots from the deployed position to the stowed position if impacted while the vehicle or mast is traveling in a forward direction.

12. The sensor mounting assembly of claim 11, wherein the mast pivots from the deployed position to a recoverable position if impacted while the vehicle or mast is traveling in a rearward direction and the impact disengages the breakaway connection fastener from the base or channel.

13. The sensor mounting assembly of claim 12 further comprising a bumper disposed within the base wherein the bumper cooperates with the mast when in the stowed position.

14. A vehicle mounted sensor bracket comprising:

a mast configured to receive a sensor at a first end;

a base configured to pivotably attach to the mast at a second end;

a shock absorber mounted to the mast at one end and the base at its other end;

wherein the base is configured to attach to a vehicle and the shock absorber predisposes the mast to either a deployed position or a stowed position.

15. The sensor bracket of claim 14, wherein the base further comprises a channel portion and a vehicle mount portion, wherein the channel portion is attached to the mast and to the vehicle mount portion at a pivot point and the shock absorber is mounted to the mast at one end and the channel portion at its other end.

16. The sensor bracket of claim 15, wherein the base further comprises a breakaway connection between the channel portion and the vehicle mount portion wherein the breakaway connection comprises fasteners connecting the channel portion to the vehicle mount portion, wherein the fasteners are comprised of material which is weaker than material forming the channel portion and the vehicle mount portion.

17. The sensor bracket of claim 16, wherein the mast rotates from the deployed position to the stowed position upon impact when the vehicle or mast is moving in a forward direction.

18. The sensor bracket of claim 17, wherein the mast rotates from a deployed position to a recoverable position when the breakaway connection is disengaged from the channel portion or the vehicle mount portion upon impact when the vehicle or mast is traveling in a rearward direction.

19. The sensor bracket of claim 18 further comprising a bumper disposed within the base adapted to cooperate with the mast when in the stowed position.
