  • Patent number: 4295227
    Abstract: A shoulder pad for football players comprising a left-hand member which fits over the left shoulder and a right-hand member which fits over the right shoulder. Each of the members is a relatively rigid member of generally inverted U-shape as viewed from the side and has a chestplate portion, a backplate portion and an arch integrally connecting the plate portions. Each member has padding on the inside thereof with the padding at the top of the arch comprising an inner portion beneath the arch and an outer portion extending laterally outwardly beyond the arch. The outer portion has front and back sections which are separate toward their outer ends for allowing the sections to spread apart on upward movement of the outer part of the shoulder. A cover pad overlies the separate outer ends of the front and back sections and is hinged to the inner portion of the arch padding for permitting the cover pad to swing upwardly on upward movement of the arm at the shoulder.

The arches are relatively narrow in relation to the width of the shoulders. Each of the members has padding on the inside thereof with the padding at the top of the arch extending laterally over the shoulder and having an inner portion generally beneath the arch and an outer portion covering the outer part of the shoulder.

  • Patent number: 4135252
    Abstract: A shoulder pad for football players comprising a chestplate portion, a backplate portion and a pair of arches integrally connecting the plate portions, the arches being laterally spaced to provide an opening for the neck of the wearer with the spacing such that the arches lie adjacent and relatively close to the neck. The arches and padding thereunder are relatively narrow in relation to the width of the shoulders so as to provide freedom for upward movement of the outer part of the shoulders without substantial interference from the arches. A pair of caps of relatively rigid material adapted to fit over the outer portion of the shoulders are flexibly connected to respective arches and have shoulder padding on the inside thereof separate from the arch padding for enabling the caps and the shoulder padding to move freely upwardly upon upward movement of the outer part of the shoulders.
