Claim 14

The seat of claim 1 wherein the arm, the first leg and the second leg are substantially linear in geometry and fold in the same plane.

Claim 15

The seat of claim 1 further including means for holding the first and second legs positively in position to support the arm when the seat is erect.

Claim 16

The seat of claim 6 wherein the holding means includes a bar which extends between the first and second legs at locations thereon spaced from said arm.

Claim 17

The seat of claim 5 wherein the first and second ends of the arm member form acute angles with the horizontal extent of the arm member and wherein the first and second legs have ends which are angled to complement those angles when the seat is in the erect condition.

Claim 18

A seat which is foldable to assume either an erect sittable condition or a collapsed storable condition wherein the seat includes at least two folding frame members, each of which comprises: an arm having first and second ends and extending generally in a horizontal direction when the seat is in the erect condition, said ends of said arm being bevelled to define a surface which faces downwardly when the seat is in the erect condition; a first leg for supporting the first end of said arm when the seat is in the erect condition; means for pivoting one end of the first leg adjacent to the first end of the arm to extend the first leg from the arm at an angle thereto when the seat is in the erect condition and to fold the first leg to extend along the arm in close proximity thereto when the seat is in the collapsed condition, said end of said first leg being bevelled to define a surface which engages the surface defined by the associated bevelled end of the arm to support the arm when the seat is in the erect condition; a second leg for supporting the second end of said arm member when the seat is in the erect condition, said second leg having an end adjacent to said second end of said arm wherein said end of said second leg is bevelled to define a surface which engages the surface defined by the associated bevelled end of the arm to support the arm when the seat is in the erect condition; and a link member pivoted adjacent to the second end of the arm and secured to the second leg, wherein said link member extends from said arm and past said first leg when the seat is in the collapsed condition to fold said second leg to extend along said first leg in close proximity thereto and wherein the link member extends generally along said arm to project said second leg at an angle from said arm when the seat is in the erect condition.

Claim 19

A seat which is foldable to assume either an erect sittable condition or a collapsed storable condition wherein the seat includes at least two folding frame members, each of which comprises: an arm having first and second ends and extending generally in a horizontal direction when the seat is in the erect condition, said ends of said arm being bevelled to define a surface which faces downwardly when the seat is in the erect condition; a first leg for supporting the first end of said arm when the seat is in the erect condition; means for pivoting one end of the first leg adjacent to the first end of the arm to extend the first leg from the arm at an angle thereto when the seat is in the erect condition and to fold the first leg to extend along the arm in close proximity thereto when the seat is in the collapsed condition, said end of said first leg being bevelled to define a surface which engages the surface defined by the associated bevelled end of the arm to support the arm when the seat is in the erect condition; a second leg for supporting the second end of said arm member when the seat is in the erect condition, said second leg having an end adjacent to said second end of said arm wherein said end of said second leg is bevelled to define a surface which engages the surface defined by the associated bevelled end of the arm to support the arm when the seat is in the erect condition; and a link member pivoted adjacent to the second end of the arm and secured to the second leg, wherein said link member extends from said arm and past said first leg when the seat is in the collapsed condition to fold said second leg to extend along said first leg in close proximity thereto and wherein the link member extends generally along said arm to project said second leg at an angle from said arm when the seat is in the erect condition.
