Shoulder strap pad
View Patent ↗A shoulder strap pad for carrying a bag on the shoulder includes a load-bearing backing member attached to or integral with the shoulder strap and a resilient cushion attached to the lower side of the backing member. The lower surface of the cushion is covered by a non-abrasive material and is formed with a plurality of raised pads for contacting the shoulder and a lengthwise-extending padded collar region along the inner side thereof for protecting the exposed surfaces of the neck and/or shoulder against chafing.

an elongated resilient substrate having a lower surface, an upper surface, first and second ends, and inner and outer elongated edges extending between the first and second ends thereof, said substrate inner edge being convexly curved over at least the regions thereof adjacent to the first and second ends thereof and having a central collar region extending inwardly of said convexly curved regions thereof;
a non-abrasive material covering the lower surface of said substrate; and
said collar region of said substrate being turned up and back in the outer direction such that at least part of the lower surface of the collar region overlies the upper surface of the region of the substrate transversely adjacent to the collar region thereof and such that the non-abrasive material on the lower surface of the collar region forms the inner edge of the pad over the length of the collar region.
2. The shoulder strap pad of claim 1 , wherein said cushion is substantially coextensive with said backing member.
3. The shoulder strap pad of claim 1 , wherein the collar region of the substrate comprises:
a lengthwise-extending raised pad on the lower surface of the substrate; and
a lengthwise-extending groove separating said raised collar pad from the transversely adjacent portion of the substrate, said lengthwise-extending collar groove forming a fold line about which said substrate collar region is turned up and folded back over the adjacent substrate region such that the collar pad and the non-abrasive covering thereon form the inner edge of the shoulder strap pad over the length of the collar region.
4. The shoulder strap pad of claim 3 , wherein:
the inner edge of the backing member is attached to the inner edge of the substrate by an inverted seam; and
the outer edge of the backing member is attached to the outer edge of the substrate by a turned edge seam.
5. The shoulder strap pad of claim 1 , wherein the substrate is comprised of moldable synthetic material.
6. The shoulder strap pad of claim 5 , wherein the synthetic material is ethyl vinyl acetate foam.
7. The shoulder strap pad of claim 5 or 6 , wherein the non-abrasive material comprises a stretchable synthetic material adhered to the lower surface of the substrate.
8. The shoulder strap pad of claim 7 , wherein the non-abrasive material is comprised of nylon fabric.
9. The shoulder strap pad of claim 1 , further comprising:
a plurality of raised pads on the lower surface of the substrate and covered by the non-abrasive material;
said pads being spaced apart in the lengthwise direction by transversely extending grooves in the lower surface of the substrate.
10. The shoulder strap pad of claim 9 , further comprising non-slip material located on the lower external surfaces of the non-abrasive material covering said raised pads.
11. The shoulder strap pad of claim 9 , wherein there are at least four of said raised pads spaced apart in the lengthwise direction of the substrate.
12. The shoulder strap pad of claim 9 , further comprising at least one lengthwise extending groove in lower surface of the substrate, said at least one lengthwise groove separating said raised pads into a plurality of transversely spaced-apart pads.
13. The shoulder strap pad of claim 9 , wherein said raised pads extend across substantially the full transverse width of the shoulder pad.
14. The shoulder strap of claim 9 , wherein:
said raised pads and said transverse grooves are molded in the lower surface of the substrate; and
the non-abrasive material is adhered to the substrate prior to the molding of the substrate.
15. A shoulder strap for a bag comprising:
at least one load-bearing strap member adapted to be attached at one or both ends thereof to a bag; and
a shoulder strap pad attached to said at least one strap member, said shoulder strap pad comprising
an elongated load-bearing backing member having an upper surface, a lower surface, first and second ends, and inner and outer elongated edges extending between said first and second ends, said inner edge being convexly curved over at least the regions thereof adjacent to said first and second ends thereof; and
an elongated cushion attached to the lower surface of the backing member, said cushion comprising:
an elongated resilient substrate having a lower surface, an upper surface, first and second ends, and inner and outer elongated edges extending between the first and second ends thereof, said substrate inner edge being convexly curved over at least the regions thereof adjacent to the first and second ends thereof and having a central collar region extending inwardly of said convexly curved regions thereof;
a non-abrasive material covering the lower surface of said substrate; and
said collar region of said substrate being turned up and back in the outer direction such that at least part of the lower surface of the collar region overlies the upper surface of the region of the substrate transversely adjacent to the collar region thereof and such that the non-abrasive material on the lower surface of the collar region forms the inner edge of the pad over the length of the collar region.
16. The shoulder strap of claim 15 , comprising two said strap members, each attached at one end to an end of said shoulder strap pad and adapted to be attached at the other end thereof to a bag.
17. The shoulder strap of claim 14 , wherein said cushion is substantially coextensive with said backing member.
18. The shoulder strap of claim 15 , wherein the collar region of the substrate comprises:
a lengthwise-extending raised pad on the lower surface of the substrate; and
a lengthwise-extending groove separating said raised collar pad from the transversely adjacent portion of the substrate, said lengthwise-extending collar groove forming a fold line about which said substrate collar region is turned up and folded back over the adjacent substrate region such that the collar pad and the non-abrasive covering thereon form the inner edge of the shoulder strap pad over the length of the collar region.
19. The shoulder strap of claim 18 , wherein:
the inner edge of the backing member is attached to the inner edge of the substrate by an inverted seam; and
the outer edge of the backing member is attached to the outer edge of the substrate by a turned edge seam.
20. The shoulder strap of claim 15 , wherein said cushion further comprises:
a plurality of raised pads on the lower surface of the substrate and covered by the non-abrasive material;
said pads being spaced apart in the lengthwise direction by transversely extending groove in the lower surface of the substrate.
21. The shoulder strap of claim 20 , further comprising non-slip material located on the lower external surfaces of the non-abrasive material covering said raised pads.
22. The shoulder strap of claim 20 , wherein there are at least four of said raised pads spaced apart in the lengthwise direction of the substrate.
23. The shoulder strap of claim 20 , further comprising at least one lengthwise extending groove in lower surface of the substrate, said at least one lengthwise groove separating said raised pads into a plurality of transversely spaced-apart pads.
24. The shoulder strap of claim 20 , wherein said raised pads extend across substantially the full transverse width of the shoulder pad.
25. The shoulder strap of claim 20 , wherein:
said raised pads and said transverse grooves are molded in the lower surface of the substrate; and
the non-abrasive material is adhered to the substrate prior to the molding of the substrate.
26. The shoulder strap of claim 15 , wherein the substrate is comprised of moldable synthetic material.
27. The shoulder strap of claim 26 , wherein the synthetic material is ethyl vinyl acetate foam.
28. The shoulder strap of claim 26 or 27 , wherein the non-abrasive material comprises a stretchable synthetic material adhered to the lower surface of the substrate.
29. The shoulder strap of claim 28 , wherein the non-abrasive material is comprised of nylon fabric.
