| 摘要 |
This invention relates to windshield wiper assemblies which include a wiping element and an articulated pressure-distributing superstructure operatively connected together so as to transmit and distribute the pressure received by the pressure-distributing superstructure from the wiper arm to spaced locations along the length of the wiping element. The pressure-distributing superstructure comprises at least one lower member having an inverted V-shaped cross section and an upper member also having an inverted V-shaped cross section. The upper member is rockably connected to the lower member by a pair of inturned tabs seated in a pair of notches in the lower member. The upper and lower members have, at least proximate the rockable connection of these members, congruent cross-sectional shapes and the top of the end of the upper member is disposed further outwardly than its bottom. The lower member has a recess in its top ridge immediately below the end of the upper member. |
