Removable seat attachment for a stroller
Embodiments include strollers having removable seats. An example stroller may include rear wheels, front wheels, and a frame including a handle portion, a rear wheel support portion, a front wheel support portion and a folding mechanism connecting the front wheel support portion and the handle portion in both an unfolded configuration and in a folded configuration. The frame may include a stroller seat support portion positioned at a first vertical position adjacent the handle portion, and a front seat attachment configured for attachment to the front wheel support portion at a second vertical position substantially lower than the first vertical position. The front seat attachment may be configured to support the front stroller seat substantially over the front wheels so that a center of gravity of the stroller system is between the front wheels and the rear wheels.
1. A stroller convertible from a single seat configuration to a double seat configuration without increasing its footprint, comprising:
two rear wheels;
only two front wheels;
a frame supported by the front and rear wheels and comprising a handle portion and left and right foldable support members extending from the handle portion towards a front end portion of the frame, the foldable support members extending in a parallel, spaced relationship and substantially within a plane that runs diagonally from the handle portion towards the front end portion of the frame;
a first seat releasably connected to the frame at a first vertical position that is closer to the handle portion than the front end portion, the first seat being connectable to the frame in either a forward or backward facing position to form the single seat configuration; and
wherein the frame receives an optional second seat assembly to form the double seat configuration, the second seat assembly comprising:
right and left seat attachments disposed along the right and left support members of the frame, respectively, at a second vertical position that is lower than the first vertical position, and wherein the second vertical position is closer to the front end portion than the handle portion; and
a second seat connectable to the right and left seat attachments in either a forward or backward facing position;
wherein the first seat and the second seat, when connected to the frame, are arranged in an inline descending configuration substantially along the plane of the frame.
