Abstract

A water sport article is provided. The water sport article includes a joint formed between a first panel having a greater thickness than a second panel. The joint includes an overlapping interface between the first and second panels where one or more of adhesive bonding, blind stitching, and taping is used to attach the first and second panels at the overlapping interface.

First claim

The invention claimed is:

1. A wetsuit, comprising:
a joint formed between a first panel having a first thickness and a second panel having a second thickness, each of the first thickness and the second thickness being substantially uniform along an entire length of the respective first panel and second panel, the joint comprising:
an overlapping interface where surfaces of a first end of the first panel and a first end of the second panel are adjacent to one another, an edge of the first end of the first panel is offset from an edge of the first end of the second panel, the first thickness of the first panel is thicker than the second thickness of the second panel, and a thickness of the overlapping interface is greater than the first thickness and the second thickness;
wherein the first panel is attached to the second panel by adhesive bonding and blind stitching, the blind stitching placed while the overlapping interface is bent and including a plurality of blind stitches each having an arcuate concave cross-section extending entirely through the second thickness of the second panel, a layer of adhesive of the adhesive bonding, and to an end point disposed within the first panel, the end point extending away and inset from the edge of the first panel and offset in a direction away from the edge of the second panel.

2. The wetsuit of claim 1 , wherein the adhesive bonding seals the joint and wherein the sealing blocks water from flowing through the joint and maintains flexibility between the first panel and the second panel at the joint.

3. The wetsuit of claim 1 , wherein the joint is arranged in at least one of a chest region, an elbow region, and a knee region of the wetsuit corresponding to articulation of a user's body in an as-worn position.

4. The wetsuit of claim 1 , wherein the first panel is less flexible than the second panel of the joint.

5. The wetsuit of claim 1 , wherein the adhesive bonding seals the joint.

6. The wetsuit of claim 1 , where the first panel and the second panel include at least one of a natural rubber material and a synthetic rubber material.

7. The wetsuit of claim 1 , wherein each of the first panel and the second panel has a bent configuration, the first panel attached to the second panel via the plurality of blind stitches in the bent configuration of each of the first panel and the second panel.

8. The wetsuit of claim 7 , wherein stitching of the blind stitching includes a linear extension defined through an entirety of the second thickness of the second panel and partially defined through a portion of the first thickness of the first panel.

9. The wetsuit of claim 8 , wherein the bent configuration of the first panel and the second panel defines a bent joint of the joint, the linear extension of each of the plurality of blind stitches corresponding to a depth of the plurality of blind stitches relative to a radius of curvature of the bent joint.

10. The wetsuit of claim 1 , wherein a second end of the first panel is free from contact with a second end of the second panel.

11. The wetsuit of claim 1 , wherein the adhesive bonding includes adhesive disposed at discrete locations across a surface area of joint.
