US Patent 10081227 Retractable vehicle sun shade with a magnetic latch

A retractable sun shade for a vehicle that rolls up into a housing at the base of the windshield. Magnets on the top edge of the shade latch with corresponding magnets mounted to the vehicle to hold the shade open when deployed. Vehicle magnets may for example be on a T-bar that is clamped to the rearview mirror arm. The housing may be held in position via tension bars on the left and right ends of the housing, which push outward against the sides of the vehicle to hold the housing in place. The system may be installed or removed without tools, adhesives, or fixtures. The system conforms to vehicles and windshields of different sizes and shapes. Deployment and retraction of the shade are rapid and simple.
