Abstract

A breakaway cover for providing emergency access to a release mechanism for a life raft on a vehicle includes a housing configured to be attached the vehicle. The housing includes a recess wherein the release mechanism may be located. The recess is protected by a cover. The cover has a first end attached the housing and a second end retained to the housing but capable of being pulled free. The cover is configured to fracture along a series of slots proximate the first end when pulled by a user.

First claim

What is claimed is:

1. An apparatus for enabling emergency access to a release mechanism for a life raft on a vehicle, the apparatus comprising:
a housing configured for attachment to the vehicle, the housing including a recess configured to contain the release mechanism therein, the recess having a height and a width perpendicular to the height;
a cover configured for attachment to the housing, the cover including a perimeter, wherein the perimeter includes a notch, the cover further including a grip, the cover having a height that is greater than the height of the recess and a width that is greater than the width of the recess, a line of slots located proximate to a first end of said cover; and
a retainer including a head, a shaft, and a longitudinal axis, wherein a dimension of the retainer transverse to the longitudinal axis is larger at the head than at the shaft, the shaft being configured to be received at least partially within the notch and the head being configured to cover at least a portion of the perimeter;
wherein the cover is configured to deflect and rotate along the line of slots in response to a force being applied to the grip such that the perimeter of the cover slides from under the head of the retainer providing access to the recess of the housing.

2. The apparatus of claim 1 , wherein the cover includes one or more openings along a line extending from a first edge of the cover to a second edge of the cover.

3. The apparatus of claim 2 , wherein the cover is configured to fracture along the line of one or more openings when the force is applied to the grip.

4. The apparatus of claim 3 , further comprising an opening in the cover configured to receive a fastener therethrough, wherein the notch and the opening are located on opposing sides of the line of openings.

5. The apparatus of claim 4 , further comprising a spacer configured to receive the retainer therethrough, the spacer including an outer surface configured to be received within the notch, the spacer having a height that is greater than a depth of the cover.

6. The apparatus of claim 5 , further comprising a compressible pad adjacent the notch, wherein a combined uncompressed depth of the cover and the pad is greater than the height of the spacer.

7. The apparatus of claim 1 , wherein the housing includes a depression surrounding the recess, wherein the depression is configured to receive the cover therein.

8. The apparatus of claim 1 , wherein the grip comprises one of a hole, a knob, a bar, or a depression with a lip.

9. An apparatus for enabling emergency access to a release mechanism for a life raft on a vehicle, the apparatus comprising:
a housing configured for attachment to the vehicle via a plurality of attachment openings, the housing including a recess configured to contain the release mechanism therein;
a cover configured for attachment to the housing, the cover including a perimeter, the perimeter including two notches, the cover further including a grip, a plurality of slots located proximate to a first end of said cover; and
two retainers, each retainer including a head, a shaft, and a longitudinal axis, wherein a dimension of the fastener transverse to the longitudinal axis is larger at the head than at the shaft, the shaft of each of the retainers being configured to be received at least partially within one of the notches and the heads of the two retainers being configured to cover at least a portion of the perimeter;
wherein the cover is configured to deflect and rotate along the line of slots in response to a force being applied to the grip such that the perimeter of the cover slides from under the heads of the two retainers providing access to the recess of the housing.

10. The apparatus of claim 9 , further including two spacers, each spacer being configured to receive one of the two retainers therethrough, each spacer including an outer surface configured to be received within one of the two notches, each spacer having a height that is greater than a depth of the cover.

11. The apparatus of claim 10 , further comprising a compressible pad adjacent the notches, wherein a combined uncompressed depth of the cover and the pad is greater than the height of the spacers.

12. The apparatus of claim 11 , wherein the grip comprises one of a hole, a knob, a bar, or a depression with a lip.

13. The apparatus of claim 12 , wherein the cover includes a hinge about which the cover is configured to fracture.

14. The apparatus of claim 9 , wherein the housing includes a depression surrounding the recess, wherein the depression is configured to receive the cover therein.
