Abstract

A pressure relief assembly includes a pressure relief device including a housing that defines at least one air passage chamber, and at least one flap secured within the air passage chamber(s). The pressure relief device is configured to securely couple to a component. A cover is secured to the pressure relief device. At least one impact-absorbing bumper is disposed between the pressure relief device and the cover. The impact-absorbing bumper(s) is configured to dampen impact energy and undesirable noise.

First claim

The invention claimed is:

1. A pressure relief assembly comprising:
a pressure relief device including a housing that defines at least one air passage chamber, and at least one flap secured within the at least one air passage chamber, wherein the pressure relief device is configured to securely couple to a component;
a cover secured to the pressure relief device, the cover having at least one securing coupler extending from a lower surface of the cover, wherein the at least one securing coupler has an exposed bottom edge; and
at least one impact-absorbing bumper disposed between the pressure relief device and the exposed bottom edge of the at least one securing coupler of the cover when the cover is secured to the pressure relief device, wherein the at least one impact-absorbing bumper is configured to dampen impact energy and reduce undesirable noise.

2. The pressure relief assembly of claim 1 , wherein the at least one impact-absorbing damper is formed on the pressure relief device.

3. The pressure relief assembly of claim 1 , wherein the at least one impact-absorbing bumper is formed of an elastomeric material.

4. The pressure relief assembly of claim 1 , wherein the pressure relief device comprises at least one retainer, wherein the cover is secured to the pressure relief device via the at least one securing coupler securing to the at least one retainer.

5. The pressure relief assembly of claim 4 , wherein the at least one impact-absorbing bumper is compressively sandwiched between the pressure relief device and the exposed bottom edge of the at least one securing coupler.

6. The pressure relief assembly of claim 4 , wherein at least a portion of the at least one impact-absorbing bumper extends from a rim of the pressure relief device.

7. The pressure relief assembly of claim 4 , wherein the at least one impact-absorbing bumper is within a retaining chamber of the at least one retainer.

8. The pressure relief assembly of claim 4 , wherein the at least one impact-absorbing bumper is outside of a retaining chamber of the at least one retainer.

9. The pressure relief assembly of claim 4 , wherein the at least one securing coupler is snapably secured to the at least one retainer.

10. The pressure relief assembly of claim 1 , wherein the at least one impact-absorbing bumper comprises a raised dampening body.

11. The pressure relief assembly of claim 10 , wherein the raised dampening body is a straight linear body.

12. The pressure relief assembly of claim 10 , wherein the raised dampening body is L-shaped.

13. The pressure relief assembly of claim 1 , wherein the pressure relief device comprises at least one forming hole, wherein the at least one forming hole is configured to allow forming material to pass therethrough to form the at least one impact-absorbing bumper.

14. A pressure relief assembly comprising:
a pressure relief device including a housing that defines air passage chambers, and flaps secured within the air passage chambers, wherein the pressure relief device is configured to securely couple to a component;
a cover that is configured to be secured to the pressure relief device, wherein the cover includes at least one securing coupler extending from a lower surface of the cover, and wherein the at least one securing coupler has an exposed bottom edge; and
impact-absorbing bumpers secured to a perimeter rim of the pressure relief device, wherein the impact-absorbing bumpers are compressed into the perimeter rim by the exposed bottom edge of the cover when the cover is secured to the pressure relief device, wherein the impact-absorbing bumpers are configured to dampen impact energy and reduce undesirable noise.

15. The pressure relief assembly of claim 14 , wherein the pressure relief device comprises at least one retainer, wherein the cover secures to the pressure relief device via the at least one securing coupler securing to the at least one retainer.

16. The pressure relief assembly of claim 15 , wherein the impact-absorbing bumpers are separate and distinct from a perimeter seal of the pressure relief device.

17. The pressure relief assembly of claim 15 , wherein two impact-absorbing bumpers are compressed between the exposed bottom edge and the perimeter rim of the pressure relief device when the cover is secured to the pressure relief device.

18. The pressure relief assembly of claim 15 , wherein the at least one securing coupler snapably secures to the at least one retainer.

19. The pressure relief assembly of claim 14 , wherein each of the impact-absorbing bumpers comprises a raised dampening body.

20. A pressure relief assembly comprising:
a pressure relief device including a housing that defines air passage chambers, and flaps secured within the air passage chambers, wherein the pressure relief device is configured to securely couple to a component;
a cover that is configured to be secured to the pressure relief device, wherein one of the pressure relief device or the cover comprises securing couplers, and the other of the pressure relief device or the cover comprises retainers, wherein the cover secures to the pressure relief device via the securing couplers snapably securing to the retainers; and
impact-absorbing bumpers including raised dampening bodies formed of an elastomeric material secured to a perimeter rim of the pressure relief device, wherein the impact-absorbing bumpers are compressed into the perimeter rim by the cover when the cover is secured to the pressure relief device, wherein the impact-absorbing bumpers are configured to dampen impact energy and reduce undesirable noise, wherein at least portions of the impact-absorbing bumpers are compressed between first portions of the securing couplers and second portions of the pressure relief device when the cover is secured to the pressure relief device, and wherein the securing couplers are connected to the lower surface of the cover at third portions that are opposite the first portions.
