Abstract
Abstract A vehicle seat that is folded and stowed in a recess in the floor of a vehicle. A rear portion of the seat has shiftable elements that are moved within channels formed in tracks. The shiftable elements may be rollers that move in box channel tracks. A front portion of the seat is supported by link arms that pivot as the seat is stowed in the recess. Locking pins on the link arms are received in a series of holes that permit fore and aft adjustment of the seat position.

Claim 1
Independent Claim
350 words
A seat mounted within a vehicle having a compartment that is converted between a passenger configuration and a cargo carrying configuration, the compartment having a floor that defines a recess and a right wheel housing and a left wheel housing on opposite sides of the floor, said seat comprising: a lower seat assembly having a front portion and a rear portion; a seat back assembly pivotally connected to the lower seat assembly; a right rail secured to the right wheel housing, said right rail defining a first channel; a left rail secured to the left wheel housing, said left rail defining a second channel; a right side shiftable element connected to the rear portion of the lower seat assembly and received in the first channel of the right rail for movement along the first channel; a left side shiftable element connected to the rear portion of the lower seat assembly and received in the second channel of the left rail for movement along the second channel; a right link arm pivotally connected on an upper end to the front portion of the lower seat assembly and pivotally connected to the floor; a left link arm pivotally connected on an upper end to the front portion of the lower seat assembly and pivotally connected to the floor; a right locking pin associated with the right link arm that selectively locks the right link arm to the right rail; a left locking pin associated with the left link arm that selectively locks the left link arm to the left rail; said seat being converted from the passenger configuration to the cargo carrying configuration by pivoting the seat back assembly onto the lower seat assembly, disengaging right and left locking pins from the right and left rails, respectively, shifting the lower seat assembly forward by moving the right and left side shiftable elements forward in the first and second channels, respectively, and pivoting the upper ends of the right and left link arms forward and downward until the lower seat assembly is received in the recess formed in the floor of the vehicle.
