Total Claims: 11
Claim 1
Independent Claim
181 words
A stroller comprising: two opposite side sections each having a pair of wheels at its lower end and an upper end portion by which a person manipulates the stroller; said sections being foldable longitudinally to a reduced length condition; means connecting said two sections for movement laterally toward and away from one another between collapsed positions in close proximity to one another and more widely laterally spaced positions of use; flexible material forming a seat extending between said two side sections, and forming also a seat back which can swing between a generally upright position for supporting the back of a sitting child and a downwardly and rearwardly swung more horizontal position for supporting a child lying more horizontally; two flexible opposite side panels connected to opposite edges of said seat back and extending upwardly therefrom to said two side sections respectively to retain a child leaning against the seat back in a plurality of different positions thereof; and means for supporting said seat back in said different positions with said side panels extending between the seat back and side sections.
Claim 2
Dependent Claim
181 words
A stroller comprising: two opposite side sections each having a pair of wheels at its lower end and an upper end portion by which a person manipulates the stroller; said sections being foldable longitudinally to a reduced length condition; means connecting said two sections for movement laterally toward and away from one another between collapsed positions in close proximity to one another and more widely laterally spaced positions of use; flexible material forming a seat extending between said two side sections, and forming also a seat back which can swing between a generally upright position for supporting the back of a sitting child and a downwardly and rearwardly swung more horizontal position for supporting a child lying more horizontally; two flexible opposite side panels connected to opposite edges of said seat back and extending upwardly therefrom to said two side sections respectively to retain a child leaning against the seat back in a plurality of different positions thereof; and means for supporting said seat back in said different positions with said side panels extending between the seat back and side sections.
Claim 3
Dependent Claim

A stroller as recited in claim 1, in which said supporting means include a plurality of fasteners secured to said side panels at spaced locations and detachably connectable to said side sections to support the seat back through the side panels in said different positions of the seat back.
Claim 5
Dependent Claim
56 words
A stroller as recited in claim 1, in which said supporting means include first connector elements attached to said side sections, and second connector elements attached to said side panels and detachably connectable to said first connector elements in a relation supporting the seat back through said side panels in different positions of the seat back.
