ABSTRACT:
A concealed quick attach and detach mechanism for releasably installing and automatically locking a seat against lateral movement on a vehicle of the type having spaced apart first and second cantilever supports which terminate in first and second laterally spaced free ends. The mechanism includes a seat pan having a housing that includes a concealed interior and an interior support axis and first and second spaced apart apertures in the pan housing aligned on the lateral support axis that open into the interior for slidably receiving the first and second supports therethrough, respectively, when the seat is installed on the vehicle. A deflectable first lock is provided in the seat pan interior in register with the support axis and laterally spaced from the first aperture. A biasing area is provided for normally maintaining the first lock in register with the support axis and for permitting the first lock to be deflected out of register with the support axis during attaching and detaching of the seat on the vehicle. A second lock is provided in the seat pan interior in register with the support axis and laterally spaced from the second aperture; and the first and second locks are spaced apart laterally from each other a distance that is substantially equal to the lateral spacing of the free ends of the cantilever supports on the vehicle on which the seat pan is to be mounted for automatic abutment against the free ends when the seat is installed to restrain the seat against lateral movement.
