Abstract
Abstract A folding seat, which becomes a semi-seat when folded, comprises a generally upright back member supported on a vehicle wall or floor, or both. Each back member has a recess in the lower portion thereof, and a folding seat member, having a projection on its under side, is hingedly mounted in the lower end of each recess. Each seat member swings between lowered, full seating position, and upswung, folded, semi-seating position. A lower back support member is carried by each seat member and rides within its associated back recess. When the seat member is swung down to full seating position the lower back support member associated therewith is moved thereby to close the recess flush with the back portion above the recess. Spring biasing means preferably urges each seat member toward folded position, or at least provides a counterbalancing effect.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
220 words
A folding seat for a transportation type vehicle comprising a generally upright back member, said back member comprising an upholstered, upper back supporting portion, and a recessed lower portion, a seat member hingedly mounted on the lower end of the back member for swinging movement about a horizontal axis between downswung position wherein the seat member extends at substantially right angles to the back member to provide a full seat, and upswung position wherein the free upper end of the seat member is seated in such recessed protion flush with the upper back portion, a projection shorter than the seat member extending substantially at right angles from the side of the seat member which is on the bottom thereof when the seat member is in its downswung, full seat position, and which is shaped to provide a semi-seat when the seat member is in its upswung position, and a lower back support member operatively connected to each seat member for movement in said recessed portion between a lowered, retracted position submerged within such recessed portion when the seat member is in its upswung position with its free end in flush seated position in the recessed portion, and a raised projected position substantially flush with the upper back supporting portion when the seat member is in its downswung, full seat position.
Claim 2
Dependent Claim
220 words
A folding seat for a transportation type vehicle comprising a generally upright back member, said back member comprising an upholstered, upper back supporting portion, and a recessed lower portion, a seat member hingedly mounted on the lower end of the back member for swinging movement about a horizontal axis between downswung position wherein the seat member extends at substantially right angles to the back member to provide a full seat, and upswung position wherein the free upper end of the seat member is seated in such recessed protion flush with the upper back portion, a projection shorter than the seat member extending substantially at right angles from the side of the seat member which is on the bottom thereof when the seat member is in its downswung, full seat position, and which is shaped to provide a semi-seat when the seat member is in its upswung position, and a lower back support member operatively connected to each seat member for movement in said recessed portion between a lowered, retracted position submerged within such recessed portion when the seat member is in its upswung position with its free end in flush seated position in the recessed portion, and a raised projected position substantially flush with the upper back supporting portion when the seat member is in its downswung, full seat position.
Claim 3
Dependent Claim
84 words
A folding seat as defined in claim 1 wherein a portion of the seat member is eccentric to its axis of pivotal movement, the lower back support member is hingedly connected to said eccentric portion to move the lower back support member slidably in such recess between its raised position closely adjacent the upper end of the recess with the seat member in its downswung, full seating position, and its lowered position, deeper within such recess, with the seat member is in upswung position.
Claim 4
Dependent Claim
84 words
A folding seat as defined in claim 2 wherein the portion of the seat back member defining the upper end portion of such recesses is curved, and forms a cam surface on which the upper end of the lower back support member rides and is moved thereby between its position substantially flush with the upper back portion above such recess with the seat member in its down-swung position, and its position deeper within said recess with the seat member in its upswung, folded position.
Claim 5
Dependent Claim
35 words
A folding seat as claimed in claim 1 wherein the seat member covers and conceals the recess and the lower back support member mounted therein when said seat member is in its upswung, semiseat-froming position.
Claim 6
Dependent Claim
32 words
A folding seat as claimed in claim 1 wherein spring means acing between the lower back Support member and a seat element biases the lower back support member toward the back member.
Claim 7
Dependent Claim
46 words
A folding seat as claimed in claim 5 wherein the spring means is mounted in biasing relation with the seat member and the lower back support member, and biases the lower back support member toward the back member and the seat member toward upswung, folded position.
Claim 8
Dependent Claim
42 words
A folding seat as claimed in claim 6 wherein the spring means is mounted in tension between a point on the recess side of each lower back support portion and a fixed seat back element at the lower end of such recess.
