A cable-linked releasing handle lets one child seat latch mechanism detach from stroller and restraint base with simpler, more intuitive operation.

An eccentric hinge keeps child seat frame members aligned during folding, avoiding finger traps and bulky joints while staying compact.

A movable safety lock engages the button assembly to stop accidental folding of a stroller support frame during infant seat installation.

A trigger-actuated joint lets infant carrier supports fold compactly yet stay stable through selective protrusion-concave engagement.

A unified latch base and cable-linked handle simplify child seat release while keeping secure attachment to strollers and restraint bases.

A dual-latch rail mechanism and single release handle simplify secure child seat attachment to both bases and stroller frames.

A releasable base, chassis, and car seat with deployable legs enables quick switching between vehicle, carrier, and stroller use.

Releasable chassis and seat connections let fold-out legs switch an infant carrier between car seat, carrier, and stroller modes.

Releasable chassis legs let one infant seat switch between car seat, carrier, and stroller modes without complex assembly.

Deployable nesting legs and standardized release interfaces let one infant carrier switch smoothly between car seat, carrier, and stroller modes.

A quadrangular wagon adapter securely fits multiple infant car seats, easing vehicle-to-wagon transfer while freeing interior space for luggage.

A pivoting seat frame and folding hub let a stroller keep multiple seating modes while collapsing into a compact form for transport and storage.

A cam sleeve aligns stroller caster wheels during leg retraction, enabling compact car seat conversion without wheel misalignment.

A spring-biased receiver lets a wheel cover lock onto wheel posts without tools while preserving hub access, reducing parts, and improving aerodynamics.

A pivoting upper and lower seat frame lets a stroller keep multiple seating modes while folding into a compact package with larger wheels.

A pivoting upper and lower seat frame lets a full-feature stroller fold compactly without sacrificing multiple seating modes or terrain handling.

A two-step locking and pivoting seat frame folds vertically within the stroller frame boundary while preserving multiple seating modes.

Foam injection molding creates a lighter baby carrier main body while preserving strength and enabling secure connection to seats and strollers.

Stationary bottom connectors and telescopic struts let the trolley fold compactly while preserving base-frame strength and carrying capacity.

A linked latch and rotating handle frame let a multi-configuration stroller fold compactly while keeping the frame locked in use.

A linked latch and pivoting grip let a multi-configuration stroller frame fold smaller while keeping unfolding and locking reliable.

Multi-directional folding with telescopic rods and stationary bottom connectors cuts storage volume while preserving trolley strength and stability.

A nested pivotal joint lets the stroller front leg fold further toward the bottom pipe, cutting folded size for easier carrying and storage.

A non-circular pivot with groove, tapered sections, and a lock lets child conveyance hinges fold while preventing finger pinching.

An external transverse frame lock replaces wear-prone internal rods, simplifying foldable carriage pivot locking and reducing injury risk.

Rotating a transverse frame member replaces hidden wires or rods, simplifying the pivot lock and reducing wear, weight, and folding injury risk.
