Abstract
Abstract The present invention provides a convertible seat apparatus and method of utilizing the same for a vehicle seat having two major alternative positions. The seat can be converted to a compact forward generally vertical position utilizing the back of the upper seat member as a cargo barrier. The seat member can also be folded into a another alternative position to utilize the back of the seat as a floor extension within the vehicle. By the use of the present invention the seat back can serve both as a cargo barrier as well as a floor extension depending upon the configuration desired.

Claim 8
Dependent Claim
66 words
A vehicle convertible seat as described in claim 1 for utilization in a vehicle having at least two separate floor levels wherein said seat in its first horizontal position is on a first vehicle floor level and when said vehicle seat is displaced to said second horizontal position, said seat back provides an extension of said first vehicle floor level over said second vehicle floor level.
Claim 9
Dependent Claim
256 words
A vehicle convertible seat comprising in combination: an upper seat member having a back in a generally vertical orientation; a femur member adjacent said upper member extending forward in a general horizontal orientation; a first link with a forward end and a rearward end, said first link forward end being pivotally connected with said vehicle and said first link extending rearwardly from said pivotal connection with said vehicle; a second link pivotally connected with said first link adjacent said rearward end of said first link, said second link being pivotally connected with said femur member at an end of said second link opposite said second link pivotal connection with said first link; a third link having first and second ends and said third link first end being pivotably connected with said vehicle rearward of the pivotal connection of said forward end of said first link with said vehicle and said third link having means of pivotable connection with said femur member and said upper seat member and wherein said seat has a first horizontal position wherein said upper seat member mates with said femur seat member and said upper seat back is above said femur member and said seat being convertible to a first vertical position from said first horizontal position wherein said seat back is rearward of said femur member and said seat being convertible to a second horizontal position wherein said mated seat members are forwardly and lowerly displaced from said first horizontal position and wherein said seat back is above said femur member.
