Abstract

A harness system for a patient transport apparatus. The harness system comprises one or more harness assemblies. Each harness assembly comprises a flexible restraint member formed of a coated fabric and comprising one or more joints in which stitches join sections of the coated fabric. Covers are attached to the coated fabric over the stitches to provide a barrier to outside contaminants and to ease cleaning of the flexible restraint member.

First claim

What is claimed is:

1. A harness assembly operable by a user for securing a patient to a patient transport apparatus, said harness assembly comprising:
a connector; and
a flexible restraint member coupled to said connector, said flexible restraint member comprising a fabric and a coating covering said fabric to protect said fabric from exposure to outside contaminants,
said flexible restraint member comprising stitches securing first and second sections of said fabric together at a joint and a covering disposed over said stitches and attached to said first and second sections to provide a barrier that protects said stitches from exposure to outside contaminants at said joint,
said flexible restraint member further comprising another joint securing adjacent sections of said fabric together.

2. The harness assembly of claim 1 , wherein said covering is sealed to said coating at said first and second sections.

3. The harness assembly of claim 2 , wherein said covering is heat sealed to said coating at said first and second sections.

4. The harness assembly of claim 2 , wherein said covering comprises urethane.

5. The harness assembly of claim 4 , wherein said coating comprises polyurethane.

6. The harness assembly of claim 2 , comprising adhesive located between said covering and said coating.

7. The harness assembly of claim 1 , wherein said covering comprises a first cover attached to said first section and a second cover attached to said second section.

8. The harness assembly of claim 1 , wherein said fabric comprises polyester webbing.

9. The harness assembly of claim 8 , wherein said fabric has a thickness of from 0.030 to 0.040 inches.

10. The harness assembly of claim 8 , wherein said fabric has a thickness of less than 0.047 inches.

11. The harness assembly of claim 10 , wherein said coating has a thickness of at least 0.005 inches.

12. The harness assembly of claim 11 , wherein said stitches are formed of nylon thread and are placed in a box X stitch pattern.

13. The harness assembly of claim 1 , wherein said coating and said covering have smooth outer surfaces to facilitate wiping of contaminants off said flexible restraint member.

14. The harness assembly of claim 1 , wherein said fabric and said coating have a combined thickness of from 0.038 to 0.047 inches.

15. The harness assembly of claim 1 , comprising a loop configured to engage said connector and secure said connector to said flexible restraint member.

16. The harness assembly of claim 15 , wherein said flexible restraint member further comprises second stitches securing third and fourth sections of said fabric together at a separate joint, separate from said other joints, and a second covering disposed over said second stitches and attached to said third and fourth sections of said fabric to provide a barrier that protects said second stitches from exposure to outside contaminants at said separate joint; and
wherein said separate joint is located to provide a connecting loop configured to facilitate coupling of the harness assembly to the patient transport apparatus.

17. The harness assembly of claim 15 , wherein said another joint secures a free end of said fabric to one of said adjacent sections of said fabric, said covering being heat sealed to said coating at said another joint such that said free end of said fabric is covered by at least one of said covering and said coating.

18. A harness system operable by a user for securing a patient to a patient transport apparatus, said harness system comprising:
a plurality of harness assemblies configured to be coupled to the patient transport apparatus, each of said harness assemblies comprising:
a connector; and
a flexible restraint member coupled to said connector, said flexible restraint member comprising a fabric and a coating covering said fabric to protect said fabric from exposure to outside contaminants,
said flexible restraint member comprising stitches securing first and second sections of said fabric together at a joint and a covering disposed over said stitches and attached to said first and second sections to provide a barrier that protects said stitches from exposure to outside contaminants at said joint,
said flexible restraint member further comprising another joint securing adjacent sections of said fabric together.

19. The harness system of claim 18 , wherein two of said plurality of harness assemblies comprise shoulder harness assemblies configured to be attached to the patient transport apparatus and crossed over a torso of the patient in an X-configuration.

20. The harness system of claim 19 , wherein said harness system is configured to meet the requirements of SAE technical standard J3027.
