Patent application #20120222191 titled "Sports garment with a seat pad, in particular for cycling" claims to have a unique method for attaching a padded section to a spandex cycling short. Here's claim 1 from the patent:
A skin-tight sports garment comprising at least a portion acting as trousers and a seat pad located in a crotch area of the garment, the seat pad comprising a front attachment region to the garment and a rear attachment region to the garment, a central portion of the seat pad being free from attachments to the garment and thus forming a loose bridge portion of the seat pad in the inner crotch area of the garment.
Having worn them myself, I know that padded sports garments have been around for years and there must be prior art for such.
What prior art addresses padded sports garments - particularly cycling shorts?
