Abstract
A heavy-duty flat wiper blade assembly has a wiper element and an extruded metallic frame. The frame has a bottom channel with a slot traversing its length in which the wiper element is maintained. The wiper element extends through the slot and outwardly from the bottom channel to make contact with a surface to be wiped. The frame has a closed upper channel that may include a fluid inlet opening for receiving wiper fluid into the channel and a fluid outlet opening for discharging the wiper fluid from the upper channel onto a surface to be wiped.
Claims14
A flat wiper blade assembly, comprising:
- a resilient wiper element extending longitudinally and having a crown, a neck and a body;
- and
- an extruded rigid metallic frame extending longitudinally between opposite ends, said frame including an open bottom channel having a pair of laterally spaced side walls and a bottom wall, said bottom wall formed with a longitudinally extending slot, said crown of said wiper element being disposed in said bottom channel, said neck extending through said slot and said body extending below said frame;
- said frame including an upper channel having a partition wall separating said upper channel from said lower channel a pair of laterally spaced side walls of said upper channel extending upwardly from said partition wall, and a top wall extending between said side walls and spaced from said partition wall to enclose said upper channel, a side wall of said bottom channel including a locally mechanically deformed protuberance extending laterally inwardly into gripping engagement with said wiper element to secure said wiper element against longitudinal movement relative to said bottom channel.
