Abstract

The present application provides various examples that may include a hose and a system. The hose may include a hose body, where an end segment of the hose body may be foldable over a clamp seat area of the hose body. There may be an opening in the end segment sized and shaped to provide access to a clamp, so as to better hold the clamp in place, while still enabling access.

First claim

The invention claimed is:

1. A system comprising:
a flexible engine passage body through which gas flows;
a hose clamp positioned over a clamp seat area of the passage body and encircling the passage body and having a clamp adjustment mechanism to adjust a tightness of the clamp around the passage body; and
an end segment of the passage body, the end segment including an annular segment and the end segment folded over the clamp, the folded end segment further including an opening sized and shaped to provide access to the clamp adjustment mechanism,
the clamp adjustment mechanism projecting radially outwardly through the opening.

2. The system of claim 1 , wherein the flexible engine passage body is an extruded body.

3. The system of claim 1 , wherein the flexible engine passage body is one or more of:
a crankcase ventilation line;
an intake line; and
an exhaust line;
wherein the system further comprises a stiffening ring at a terminal end of the end segment.

4. The system of claim 1 , wherein the flexible engine passage body is folded along one or more fold lines, and wherein the one or more fold lines are living hinges.

5. The system of claim 1 , further comprising a circumferential retainer ring formed into the passage body disposed to contact the clamp to prevent movement of the clamp beyond a predetermined amount.

6. The system of claim 5 , wherein the retainer ring is discontinuous, or wherein the retainer ring is an annular concavity formed into the end segment.

7. The system of claim 5 , wherein the retainer ring is continuous around the circumference, the retainer ring being an annular concavity formed into the end segment.

8. The system of claim 1 , wherein the opening is a rectangular window having a continuous perimeter edge formed integrally with the end segment, the opening providing access to the clamp seat area, the clamp adjustment mechanism positioned in the clamp seat area.

9. The system of claim 1 , wherein the flexible engine passage body houses an intake air passage.

10. The system of claim 1 , wherein the end segment includes a circumferential retainer disposed to restrict movement of the clamp to within a predetermined amount, wherein the annular segment provides a radial offset of the end segment from the passage body.

11. The system of claim 1 , wherein the opening is a notch formed in the folded end segment.
