US Patent 10427551 Vehicle seat conversion apparatus and method

An assembly called an adapter base allows for replacement of an original equipment seat with a non-original equipment seat in a vehicle by reuse of original equipment seat legs with horizontally oriented fasteners to a non-original equipment seat configured for vertical oriented fasteners. The method involves removing the original seat to make the original equipment seat legs then available for attachment to an adapter base which allows for secure installation of non-original seats in various configurations.
