A device for transporting a child, particularly one that is provided with a collapsible seat. The seat is coupled to the obliquely upward extending first arms by means of connecting arms which can slide away from the undercarriage in the first arms. This sliding movement takes place automatically after sufficient downward rotation of the second arms.

A child stroller apparatus includes a first and a second leg portion, a handle frame having a side segment that is coupled with the first leg portion via a pivot connection, a child seat assembled on the first leg portion, the child seat being slidable along the first leg portion, and a linkage respectively connected with the side segment and the child seat, whereby a sliding movement of the child seat along the first leg portion is linked to a rotation of the handle frame relative to the first leg portion.

A system to transport infant children is provided. The system comprises a chassis having a frame; a pair of rear legs pivotally coupled to the frame at a rear leg pivoting axis; and a pair of front legs, each front leg pivotally coupled to a respective rear leg at a front leg pivoting axis, wherein the rear legs and the front legs are retracted and proximate the frame in a first transport condition, and wherein the rear legs and the front legs are deployable away from the frame to a second transport condition. The system may also comprise an infant car seat coupled to the chassis.

A convertible infant car seat and stroller assembly is provided, comprising: an infant car seat shell; and a chassis coupled to the infant car seat, comprising: a frame; a pair of rear legs pivotally coupled to the frame; and a pair of front legs, each front leg pivotally coupled to a respective rear leg, wherein the rear legs and the front legs are retracted and proximate the frame in a first transport condition usable as in infant car seat, and wherein the rear legs and the front legs are deployable away from the frame to a second transport condition usable as a stroller; wherein, in the second transport condition, the front legs and the rear legs are releasably secured to the chassis frame in the deployed position to prevent the front legs and the rear legs from pivoting.

A convertible stroller is provided that includes a shell configured to support an infant. A pair of rear legs are pivotally coupled to the shell and a pair of front legs are pivotally coupled to a respective rear leg. The rear legs and the front legs are retractable to a first transport condition, and deployable away from the shell to a second transport condition usable as a stroller. A front wheel may be coupled to each front leg that is rotatable about a horizontal axle in the second transport condition. Each front wheel has a post that acts as an axis of rotation in the second transport condition. A cam sleeve is provided that is movably disposed on each post. In a first position, the cam sleeve allows rotation about the axis of rotation, and in the second transport condition prevents rotation of the front wheel about the axis of rotation.

An infant transport system is provided, comprising: an infant car seat; and a chassis coupled to the infant car seat. The chassis comprises a frame; a pair of rear legs pivotally coupled to the frame; and a pair of front legs, where each front leg is pivotally coupled to a respective rear leg, and wherein the rear legs and the front legs are retracted and proximate the frame in a first transport condition, and wherein the rear legs and the front legs are deployable away from the frame to a second transport condition. In the first transport condition, the rear legs are releasably secured to the infant car seat and the front legs are releasably secured to the chassis.

A system to transport infant children usable as an integrated unit or with a universal tower attachment system is provided that includes a base configured to be secured to a portion of an automobile; a chassis releasably coupled to the base; and a shell. The shell includes a frame configured to support an infant; a carrying handle movably coupled to the frame at a hub; a first latch operable to selectively, releasably couple the shell to the chassis; and a second latch adjacent the hub to selectively, releasably couple the shell to the tower attachment system. The shell may be selectively coupled to the chassis or to the tower attachment system.

A child seat detachably installable on a child stroller apparatus includes a seat frame including a first and a second frame portion rotatable relative to each other for unfolding and collapsing the child seat, a side coupling part fixedly connected with the first frame portion and pivotally connected with the second frame portion, a tray connected pivotally with the side coupling part, a tray latch assembled with the side coupling part and operable to engage with the tray for locking the tray in a deployed position for use, and a linking member operatively connected with the tray latch and the second frame portion. A rotation of the second frame portion for collapsing the child seat causes the linking member to move for urging the tray latch to disengage from the tray.

A stroller includes a left side support frame; a right side support frame; and a connecting frame which connects the left and right side support frames together, and which defines a seat rest for a child; wheels rotatably connected to a front and rear of each support frame; at least one rear footboard connected to a rear end of the stroller; an adjustment assembly which rotatably connects the rear wheels to a rear of the support frames, between a first inward operative position and each rear footboard to a vertical position for use when a child is not standing on the at least one rear footboard and a second outward operative position and each rear footboard to a horizontal position which increases a footprint of the stroller for use when a child is standing on the at least one rear footboard.
