The present invention discloses a backrest angle adjusting mechanism including a first support, a second support, a locking member and a reset member. The first and second supports are pivotally connected to each other and are respectively connected to a backrest tube and a stroller frame, and multiple engaging stages are formed between the first and second supports. The locking member is slidably provided between the first and second support, and has a lock position and a release position. The locking member is engaged at any engaging stage when at the lock position; when the driving member moves, the locking member is driven to slide and depart from the engaging stage and becomes located at the release position, thereby implementing angle adjustment of the backrest tube. During a folding process of the stroller frame, automatic folding of the backrest tube can be achieved by folding the frame stroller or by a seat fabric pulling the backrest tube that then moves with the stroller frame, thereby better simplifying operations of angle adjustment of the backrest tube and folding of a baby stroller. The present invention further discloses a baby stroller having the backrest angle adjusting mechanism.

A handle assembly for an infant carrier is provided. The handle assembly allows the handle to be oriented in one of a plurality of positions, such as a stroller position, and infant carrier position and a car seat position. The handle assembly may include a locking mechanism allowing a handle extension to be extended only when the handle rotated to the stroller position. The handle assembly may also include a blocking mechanism that prevents the handle from rotating from the stroller position if the handle is extended.

A twice-foldable stroller including a frame main body which is configured to have right and left front-angle frames to support front wheels and a horizontal frame connected at a lower part between the right and left front-angle frames, right and left rear-angle frames to support rear wheels and connecting frames connected between the right and left rear-angle frames and the right and left front-angle frames, and vertical frames connected to the right and left connecting frames; seat frames; backrest frames; support frames; extension frames; canopy frames rotatably connected to the extension frames; and handles, each connected to the extension frames, wherein right and left central portions are rotatably connected to each other.

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.
