Test fixture for the aging of wiper blades in a laboratory

A test fixture for testing vehicle wiper blades in a laboratory, comprising:

• a frame including a pair of longitudinally extending side beams, a pair of transversely oriented end beams, and a center support beam extending between said end beams generally parallel to said side beams;
• first and second flexible plates being formable into respective curved configurations replicating automotive windshields;
• support members mounted on said side beams and said center support beam to engage said flexible plates to form said flexible plates into said curved configurations;
• and
• a plurality of mounting arms supported on said frame at one of said end beams and projecting over said flexible plates, said mounting arms being detachably connectable to a wiper blade for placement thereof in engagement with said flexible plates.

A test fixture for conducting laboratory testing of automotive wiper blades comprising:

• a frame including a pair of longitudinally extending side beams, a pair of transversely oriented end beams, and a center support beam extending between said end beams generally parallel to said side beams, each of said side beams and said center support beam having formed therein spaced apart apertures;
• support members mounted in selected said apertures on said side beams and said center support beam, said support members being arranged in opposing pairs with one of said opposing pair of support members being positioned on said center support beam;
• a first flexible plate mounted on said support members between said center support beam and one of said side beams, said first flexible plate being oriented in a curved configuration replicating an automotive windshield;
• a second flexible plate mounted on said support members between said center support beam and the other of said side beams, said second flexible plate also being oriented in a curved configuration;
• and
• a plurality of mounting arms supported on said frame at one of said end beams and projecting over said flexible plates, said mounting arms being detachably connectable to a wiper blade for placement thereof in engagement with said flexible plates.
